SENSOR ZONE CLEANING SYSTEM

CROSS-REFERENCE TO RELATED PATENTS

[0001] This application claims the benefit of U.S. Provisional Application 63/521,559 filed June 16, 2023, the disclosure of which is incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

[0002] The present disclosure generally relates to cleaning system for a sensor. This cleaning system can be used to selectively clean a surface of a sensor and is suited for use in the field of vehicles.

BACKGROUND

[0003] Use of cameras and sensors on vehicles is increasing. Due to the impact of environmental elements to these cameras and sensors, associated camera and sensor systems can experience a loss in effectiveness. Mounted nozzles can be used to clean the surfaces or lenses of these systems. Self-driving and autonomous vehicles, for example, which are also increasing in popularity and production, typically require an even greater number of cameras and sensors for navigation and guidance, driving and safety, and internal performance as compared to more traditional vehicles. In order to optimize the cleaning process, conventional washer nozzles are typically uniquely arranged on each different type of vehicle, and with respect to each structure to be cleaned, in order to properly direct cleaning fluid spray onto a particular region of a surface. In order to keep cameras and sensors functioning, washer nozzles are typically arranged for a standard cleaning protocol, directing cleaning fluid spray onto a target surface for a certain period of time.

[0004] Unfortunately, conventional washer nozzles and related cleaning devices suffer from numerous drawbacks, including a lack of flexibility when cleaning debris off a targeted surface. For example, conventional washer nozzles and related cleaning devices utilize a single source nozzle activation protocol. Further, these conventional washer nozzles and related cleaning devices clean the entire sensor or surface thereof even if only one area needs to be cleaned which increases consumption of cleaning fluid.

[0005] The drawbacks set forth are especially limiting with respect to cleaning systems for sensors, particularly those associated with self-driving and/or autonomous vehicular systems, which often require more effective cleaning due to the impact of environmental elements to connected systems that can lose effectiveness and, if uncorrected, lead to impairment of normal system function and/or vehicle operation. In newer vehicle designs requiring a greater number of cameras and sensors, such as for self-driving or autonomous vehicles, the need for serviceability, space constraints, and weight constraints make conventional nozzle washer nozzles and related cleaning devices undesirable and impractical.

[0006] Considering the challenges above and the evolving strategies required to deal with the challenges, there remains a continued need for a cleaning system that can be used to clean a wide array of sensors and provide multiple optimized cleaning options based on particular cleaning needs. The cleaning system should be able to provide multiple spray pattern solutions (e.g. different spray types, time, and angles) to achieve cleaning objectives while optimize cleaning and cleaning fluid consumption based on a particular debris condition on a particular portion of the sensor surface. The cleaning system should be standardized with common components and modules that will be efficiently assembled and mounted to provide improved cleaning efficiency while managing cost.

The cleaning system provides selective activation of each spray nozzle or a portion of the plurality of spray nozzles with the at least one e-valve and/or fluid pump to tailor cleaning of the surface with two different spray patterns.

[0021 ] An embodiment of a method of cleaning a sensor with a cleaning system is also disclosed. The sensor has a surface comprising at least one zone. The cleaning system comprises a plurality of spray nozzles adapted to spray cleaning fluid onto the sensor. The cleaning system also comprises e-valves or fluid pumps in electronic communication with a body control module (“BCM”) of a vehicle. The e-valves or fluid pumps are adapted to deliver cleaning fluid from a fluid conduit to the one or more of the plurality of spray nozzles. The method comprising the steps of:

• detecting a debris deposit including but not limited to dirt, dust, mud, water, bug protein, ice, and frost on the surface of the sensor; • determining a response to clean the debris deposit; and

[0027] Advantageously, the cleaning system and method of cleaning the sensor allows for (1) cleaning of the sensor surface (general cleaning), (2) cleaning of zones on the sensor surface (zone cleaning), and (3) cleaning of target areas on the surface (precise target cleaning). As such, the cleaning system provides for efficient use of cleaning fluid because zones and/or target areas requiring cleaning can be cleaned separately as needed (as opposed to cleaning the whole sensor surface). Plus, the cleaning system provides numerous optimized cleaning options (e.g. cleaning protocols) based on cleaning needs. The cleaning options can include activation of the plurality of spray nozzles to provide multiple spray pattern solutions including spray patterns such as fan, jet, etc., at various attack angles.

DETAILED DESCRIPTION

[0049] A cleaning system for a sensor is disclosed. Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, various embodiments are illustrated and generally designated at 10, 210, and 410. Various embodiments of the cleaning system disclosed herein include a mounting bracket 12, 212, 412, a fluid conduit 14, 214, 414, a plurality of spray nozzles 16, 216, 416 and at least one electronic valve (“e-valve”) 18, 218 and/or fluid pump 418. The cleaning system 10 may be utilized for delivering cleaning fluid to a surface of any number of sensors or cameras on a vehicle or to another surface on the vehicle, such as a front windshield, a rear windshield, a headlight, or a headlamp. The term “cleaning fluid” encompasses fluid substances that are capable of flowing, including liquid, air, and mixtures thereof. While the cleaning system 10 is discussed below in connection with a sensor 20 or a camera surface, e.g., cleaning and maintaining a surface 22 such as a lens or a camera or a sensor on a vehicle, the cleaning system 10 and method disclosed herein is suitable for use in a wide range of other vehicular and non-vehicular industrial applications.

[0050] The making and using of the embodiments are discussed in detail below.

It should be understood, however, that the detailed description and specific examples, while indicating a particular manner of making and using the cleaning system, are intended for purposes of illustration only and are not intended to limit the scope of the connector. In the associated drawings, the same reference numerals will be used to refer to the same components. In the following description, various operating parameters and components are described for different constructed embodiments. These specific parameters and components are included as examples and are not meant to be limiting. [0051] It is noted that the components of the cleaning system 10 are schematically represented in Figures, and are not necessarily drawn to scale relative to each other or the vehicle. It is also noted that the number and location of the components of the fluid spray system can vary from the illustrated embodiment, and it will be understood by those skilled in the art that the fluid spray system can use different numbers of components and in different locations in accordance with the principles of the present disclosure. Further, the structural position of the various components as described, such as upper, lower, top, bottom, etc., is not absolute, but rather relative. These orientation expressions are appropriate when the various components are arranged as shown in the figures, but when the position of the various components in the figures is changed, these orientation expressions are also changed accordingly.

[0052] The cleaning system 10 provided is typically used in conjunction and fluid communication with a cleaning fluid reservoir for storing a cleaning fluid and a pump that pressurizes the cleaning fluid for delivery to the plurality of spray nozzles 16 and ultimately cleaning of a targeted surface or portion thereof. The cleaning system 10 is also typically used in conjunction with and is typically in electronic communication with a controller.

[0053] The cleaning system 10 is described herein for use with a vehicle. The vehicle typically includes the reservoir for storing a supply of the cleaning fluid and the pump that pressurizes the cleaning system 10 to allow for cleaning fluid delivery to a surface of the sensor 20. The pump can be integrated into the reservoir or situated at another location for conveying the cleaning fluid from the reservoir to the cleaning system, and more particularly to the fluid conduit 14 of the cleaning system 10.

[0054] The sensor 20 is typically mounted to the cleaning system. The cleaning system 10 is designed to work with and clean a wide array of different sensor types. As used herein, the term “sensor” can encompass any sensor aiding the vehicle's operator in viewing the vehicle's environment, including at least one camera or other optical sensor. The sensor 20 can be provided at various locations on the vehicle, such as at the front, side, or rear of the vehicle, including at a hood, cowl screen, wiper arm, bumper, spoiler, or center high-mounted stop lamp. The sensor 20 may accordingly be a headlamp (H/L) sensor, front sensor, or rear sensor (i.e. a backup camera), among others.

[0055] The sensor 20 defines a surface that can be further divided into two or more zones. That is, in a typical embodiment, the surface comprises at least two zones. The sensor 20 has a field of view degree, which refers to the extent of the observable area in degrees that the sensor 20 can capture at any given moment. The field of view degree can vary depending on the type and design of the sensor 20. For example, in cameras, the field of view degree is determined by factors like the focal length of the lens and the size of the camera sensor. Wide-angle lenses typically have a larger field of view degree, while telephoto lenses have a narrower field of view degree. Similarly, in applications like LiDAR (Light Detection and Ranging) or radar, the field of view degree is determined by the scanning mechanism and the sensor's design parameters. In some embodiments, the field of view degree is selected from a field of view degree of from 1 to 360°, 30 to 360°, or 45 to 360°. In one embodiment, the sensor 20 is a 180° sensor. In another embodiment, the sensor 20 is a 360° sensor.

[0056] The sensor 20 is in electronic communication with the controller, which is in vehicular applications often referred to as a body control module (“BCM”). The BCM is a centralized electronic control unit that manages various electrical functions within a vehicle. The BCM acts as a hub, connecting and controlling various systems such as lighting, power windows, door locks, climate control, and, in this example, the cleaning system 10 described herein. The BCM receives input from various sensors located throughout the vehicle, in this case, the sensor 20 of the subject cleaning system 10 that is being cleaned and maintained, and sends commands to the components of the cleaning system, e.g. the pumps, e-valves, etc. to perform specific functions. To this end, the BCM serves to coordinate selection, use, and operation of the multiple cleaning options provided with the cleaning system.

[0057] As set forth above, the cleaning system 10 comprises the mounting bracket, which is referred to numerically as 12 and 212 in the Figures. The mounting bracket 12 can comprise various structures (e.g. nozzle mounts, sensor mounts, etc.jfor coupling the components (e.g. the plurality of spray nozzles 16, fluid conduit 14 (including portions thereof), the e-valve(s) 18, the sensor 20, etc.). In some embodiments, the mounting bracket 12 can comprise a socket for receiving and holding one of the components. Other structures for receiving and holding the components on the mounting bracket 12 are possible. Multiple sockets, each for holding a different component, can be provided. Such structures can be adapted for removably retaining the components, or for non-removably retraining the components such as the nozzle mounts referred to below. In some embodiments, one or more of the components, or a portion of one or more of the components, may be integrally formed with the mounting bracket 12. In being integrally formed, the one or more of the plurality of spray nozzles 16, fluid conduit 14 (including portions thereof), the e-valve(s) 18, the sensor 20, etc., or a portion of the plurality of spray nozzles 16, fluid conduit 14 (including portions thereof), the e-valve(s) 18, the sensor 20, etc., can be integrated with or integral to the mounting bracket 12. Regardless of how the various components are coupleable with the mounting bracket 12, the mounting bracket 12 establishes mounted positions of the sensor 20 and the plurality of spray nozzles 16, and in their respective mounted positions, the plurality of spray nozzles 16 can be positioned to spray cleaning fluid onto the sensor 20.

[0058] In any embodiment of the mounting bracket 12 disposed herein, the mounting bracket 12 can be a single or multiple piece body made of a plastic material, and may be manufactured, for example, via injection molding or additive manufacturing, e.g. 3-D printing. In one example, the mounting bracket 12 is a plastic injection molded structure. In another example, the mounting bracket 12 is a 3D printed structure having multiple layers of plastic material deposited by an additive manufacturing machine. It is to be appreciated that other materials and manufacturing methods for the combination mounting bracket 12 are possible, including a metal bracket manufactured by stamping, casting, etc.

[0059] Retention members on the mounting bracket 12 and/or components (spray nozzles, e-valves, fluid lines, etc.) can aid in retaining the components on the mounting bracket 12 or otherwise coupling the components with the mounting bracket 12. Suitable retention members include fasteners (e.g. threaded fasteners such as bolts, screws, etc., push fasteners, clamp fasteners, etc.) connectors (e.g. quick connectors, threaded connectors/connections, snap-fit connectors, etc.), couplings (e.g. snap-fit couplings, male-female couplings, press-couplings, etc.) clamps, adhesives, and the like, as well as various combinations thereof.

[0060] The mounting bracket 12 comprises a retention point 26 connectable to a support member of the vehicle. In various embodiments, the mounting bracket 12 can be installed on the vehicle, with at least one of the retention point 26. The retention point 26 is connectable to a support member on the vehicle, such as on a chassis or frame of the vehicle. Various connection means can aid in connecting the mounting bracket 12 with the support member at the retention point 26. Suitable connection means include fasteners (e.g. threaded fasteners such as bolts, screws, etc., push fasteners, clamp fasteners, etc.), connectors (e.g. quick connectors, threaded connectors/connections, snap-fit connectors, etc.), couplings (e.g. snap-fit couplings, male-female couplings, press-couplings, etc.) clamps, adhesives, and the like, as well as various combinations thereof. The retention point 26 and connection means can be configured to mount the mounting bracket fixedly or adjustably 12 on the support member of the vehicle.

[0061] The mounting bracket 12 can mount at least the sensor 20. In a typical embodiment, the mounting bracket 12 at least partially defines a sensor socket that receive the sensor, which is referred to numerically as 28, 228, 248 in the Figures. In the embodiments illustrated in the Figures, the mounting bracket 12 includes a plurality of walls and three of the retention point 26. Each of the three retention point 26 include one or more fastening orifices, which can be used to fasten, e.g. couple with a bolt or other coupling element, the mounting bracket 12 to the vehicle. Further, the plurality of walls defines the sensor socket. In the embodiments illustrated, the sensor socket is defined, at least in part defined, by four walls. In the embodiments illustrated, a first and a second wall define mounting orifices which can be used in conjunction with a fastener to couple or mount the sensor 20 to the bracket. In most embodiments, the mounting bracket 12 can mount the fluid conduit 14, the plurality of spray nozzles 16, and/or the at least one e-valve 18 and/or fluid pump.

[0062] In various embodiments, the sensor socket is typically shaped to accommodate sensors of different size and shape. In the embodiments illustrated in the Figures, the sensor socket has a rectangular profile defined by the four walls. However, it should be appreciated that the sensor socket could have a circular profile defined by one continuous wall or even a different shape as would be required for various sensor types and brands. [0063] In a preferred embodiment, the mounting bracket 12, 212 further comprises a plurality of nozzle mounts, each nozzle mount adapted to retainably receive each of the plurality of spray nozzles. As such, the mounting bracket can be referred to as a “combination” bracket because the mounting bracket mounts to the vehicle and also allows for the spray nozzles and the sensor to be attached or coupled thereto. The plurality of nozzle mounts (or nozzle module mounts in some embodiments) are adapted to retainably receive different types of spray nozzles. Some embodiments of the mounting bracket include a nozzle bracket that is integral with the mounting bracket. Some embodiments of the mounting bracket include the nozzle bracket, which is referred to numerically as 24 and 224 in the Figures. In some embodiments, the nozzle bracket is integrated with the mounting bracket. In some such embodiments, the nozzle bracket is simply a part of, or portion of, the mounting bracket. In other embodiments, the nozzle bracket can be formed as separate portion and then coupled with a main portion to complete the mounting bracket. In such embodiments, the nozzle bracket can be coupled to the mounting bracket, the sensor, and/or the vehicle.

[0064] In some embodiments, the nozzle bracket 24, 224 includes a plurality of nozzle mounts. As described above, the nozzle bracket is typically part of the mounting bracket can also be coupled to the sensor. Each of the nozzle mounts are adapted to retainably receive different types of spray nozzles or nozzle modules. In some embodiments, the nozzle mounts utilize a nozzle socket and a snap-lock element, such as a snap-lock web, can be provided at any suitable location on the spray nozzle and/or the e-valve. In such embodiments, the snap-lock element is provided on the valve body and is engageable with a snap-lock receiver to retain the spray nozzle (an e-valve in some embodiments) in the mounted position on the nozzle bracket. In various embodiments, the nozzle mounts can comprise fasteners (e.g. threaded fasteners such as bolts, screws, etc., push fasteners, clamp fasteners, etc.), connectors (e.g. quick connectors, threaded connectors/connections, snap-fit connectors, etc.), couplings (e.g. snap-fit couplings, male-female couplings, press-couplings, etc.) clamps, adhesives, and the like, as well as various combinations thereof.

[0065] The cleaning system 10 includes the plurality of spray nozzles, which is referred to numerically as 16 and 216, 416 in the Figures. In various embodiments, the cleaning system 10 includes 2, 3, 4, 5, 6, 7, 8, 9, or 10 spray nozzles. In various embodiments, each spray nozzle is in fluid communication with a dedicated e-valve or fluid pump.

[0066] In some embodiments, a particular nozzle(s) and e-valve can be referred to as a nozzle module. In many embodiments, the cleaning system 10 includes at least two of a nozzle module, each nozzle module comprising at least one nozzle and at least one of the at least one e-valve 18 and/or fluid pump. In various embodiments, the cleaning system 10 includes 2, 3, 4, 5, 6, 7, 8, 9, or 10 nozzle modules. Accordingly, the cleaning system 10 can comprise 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 nozzle mounts on the mounting bracket 12 or the nozzle bracket 24, with each nozzle mount being adapted to retainably receive different types of nozzle modules.

[0067] In some embodiments, the cleaning system 10 comprises at least one nozzle module including one of the plurality of spray nozzles 16 and one of the at least one e-valve 18 and/or fluid pump. The cleaning system 10 in Figure 1 is an example of such an embodiment as Figure 1 includes seven nozzle modules with each nozzle module including a nozzle and an e-valve. In the embodiment of Figure 1 , the cleaning system 10 includes 7 of the nozzle module. In some embodiments, the nozzle bracket 24 comprises a plurality of nozzle mounts, and each nozzle mount is adapted to mount or retainably receive each of the at least two of the nozzle modules. In the embodiment illustrated in the Figure 1 , the nozzle bracket 24, which is part of the mounting bracket 12 comprises seven nozzle mounts.

[0068] In some embodiments, the cleaning system 10 comprises at least one nozzle module including two of the plurality of spray nozzles 16 and one of the at least one e-valve 18 and/or fluid pump. For example, the cleaning system 10 can comprise 1, 2, 3, 4, or more nozzle modules, with each nozzle module including two nozzles and an e-valve 18 (or pump). An example nozzle module could include two nozzle modules with each nozzle module including two spray nozzles and an e-valve. Another example nozzle module could include three spray nozzles and an e-valve 18.

[0069] In some embodiments, a ratio of the plurality of spray nozzles 16 to the at least one electric valve 18 and/or fluid pump is 1 : 1. In Figure 1 , each spray nozzle is coupled with an e-valve 18. In other embodiments, a ratio of the plurality of spray nozzles 16 to the at least one electric valve and/or fluid pump is greater than 1:1. For example, the embodiment of Figure 2 includes seven spray nozzles and five e-valves (including two manifold e-valves). [0070] In some embodiments, the nozzle mount can be an opening or a notch that is defined by the mounting bracket 12 or nozzle bracket 24. In other embodiments, the nozzle mount is a coupling element shaped to mount a spray nozzle or a nozzle module. In most embodiments, the nozzle mount is generic and can accommodate various types of spray nozzles and various types of nozzle modules.

[0071] The cleaning system 10 includes the fluid conduit 14. The fluid conduit 14 forms a fluid passageway which provides pressurized cleaning fluid to the water to the plurality of spray nozzles 16. As such, the fluid conduit 14 is in fluidic communication with the plurality of valves and the plurality of spray nozzles 16, and also in fluid communication with a source of a pressurized cleaning fluid. In one embodiment, the fluid conduit 14 comprises at least one quick connect coupling 30 connecting the fluid conduit 14 to the source of the pressurized cleaning fluid. Advantageously, in many embodiments, the fluid conduit 14 comprises a single source supply inlet configured to provide cleaning fluid to the plurality of spray nozzles 16.

[0072] As is illustrated, the fluid conduit 14 can comprise one or more segments. The one or more segments can be rigid or flexible. In some embodiments, the segments comprise a first and a second end, with each end of the segment comprising a coupler. In the embodiment of Figure 1, the fluid conduit 14 comprises a first segment including the supply inlet including the quick connect coupling 30 for efficient coupling to a supply line (not illustrated), a second segment having a 90° turn and extending between two side nozzle modules and three upper nozzle modules, and a third segment having a 90° turn and including another quick coupler 34 and extending between the three upper nozzle modules and two additional side nozzle modules. Advantageously, the quick connect coupling 30 functions as (is) a single source supply inlet that provides cleaning fluid to the plurality of spray nozzles 16.

[0073] In the embodiment of Figure 2, the fluid conduit 214 comprises a first segment 214a including the supply inlet including the quick coupler 230 for efficient coupling to the supply line 232. The fluid conduit 214 is in fluid communication with the e-valves and seven spray nozzles. The first and fifth manifold valve each feed two spray nozzles, whereas the second, third, and fourth manifold valves each feed a single spray nozzle. The fluid conduit 214 also includes a plurality of flexible segments that provide cleaning fluid to each of the plurality of spray nozzles 216. Advantageously, the quick coupler 230 functions as (is) a single source supply inlet that provides cleaning fluid to the plurality of spray nozzles 216.

[0074] The cleaning system 10 includes the at least one e- valve and/or fluid pump. The e-valve or fluid pump can be electronically controlled to selectively allow ingress of cleaning fluid into the spray nozzle. In most embodiments, the cleaning system 10 is connected to a power source, which provides electricity to power the e- valve or fluid pump. In a typical embodiment, the BCM is the power source or power supply. In some embodiments, the mounting bracket 12 includes at least one power connection, the power connection being connectable to the power source. The sensor and/or at least one e-valve and/or fluid pump can be electrically coupled with the power connection to be supplied with power from the power source. In one embodiment, the power connection can be an electrical socket and can be connected with a suitable plug and conductor in operative electrical connection with the power source. In another embodiment, the power connection can be an electrical plug connectable with a suitable socket and conductor. In another alternative embodiment, one or more of the components (e.g. sensor, e-valve, and/or fluid pump) can have an individual power connection.

[0075] An e-valve or fluid pump activates each or a portion of the plurality of spray nozzles. In the embodiment of Figure 1, activation of the spray nozzles occurs via direct mounted e- valves and the spray nozzles (nozzle modules). In the embodiment of Figure 2, activation of the spray nozzles occurs via remote mounted e-valves, which are in fluid communication with the spray nozzles. In the embodiment of Figure 3, fluid pumps eliminate the need for e-valves, and activation occurs via one or more fluid pumps.

[0076] In the embodiment illustrated in Figure 1, the cleaning system 10 includes seven e-valves, one e-valve 18 for each spray nozzle 16. The e-valve 18 is a control device used manage the flow of cleaning fluid to one or more of the spray nozzles 16. While not limited in design for purposes of the subject cleaning system, the e-valve 18 integrates electronic components with valve mechanisms to enable precise control, monitoring, and delivery of the cleaning fluid to the spray nozzle(s) and ultimately the surface of the sensor 20. The e-valve 18 can comprise a valve body, actuator, sensors, and electronic control unit (“ECU”). The actuator, powered by electricity, regulates the valve's opening and closing, allowing for accurate flow adjustment. In some embodiments, sensors provide real-time data on parameters like pressure, temperature, and flow rate, facilitating automated control and feedback mechanisms. In some embodiments, the ECU processes sensor inputs and executes control algorithms to optimize valve performance based on preset parameters or external commands. To this end the ECU improves cleaning system 10 efficiency, reduces manual intervention, and enables remote operation and monitoring through connectivity options including direct electronic (wired) connections, Wi-Fi or industrial network connections, and other connections that allow communication between the BCM and the at least one e- valve 18.

[0077] In a typical embodiment, the e-valve 18 is a solenoid valve. Solenoid valves use an electromagnetic coil to actuate a plunger, which opens or closes the solenoid valve. Of course, the cleaning system 10 is not limited to a particular configuration of e-valve 18 and non-limiting examples of types of the valve body include proportional valves, motorized valves, electrically actuated ball valves, electrically actuated butterfly valves, electrically actuated gate valves, and electrically actuated diaphragm valves.

[0078] The cleaning system 10 includes a plurality of spray nozzles 16 adapted to spray cleaning fluid onto the surface of the sensor 20. The at least one e-valve 18 and/or fluid pump is in electronic communication with the BCM, in fluid communication with the fluid conduit 14, and adapted to deliver cleaning fluid from the fluid conduit 14 to one or more of the plurality of spray nozzles 16. The cleaning system 10 provides selective activation of each spray nozzle 16 or a portion of the plurality of spray nozzles 16 with the at least one e-valve 18 and/or fluid pump to tailor cleaning of a specific zone on the surface in response to instructions from the BCM.

[0079] Each of the plurality of spray nozzles 16 can be different and in many embodiments of the cleaning system 10 are selected to provide efficient, optimized cleaning for a particular sensor and under particular conditions. The nozzle bracket 24 allows for efficient construction of the cleaning system 10 with and use of various combinations of spray nozzles 16. As is explained herein, each of the plurality of spray nozzles 16 can provide a different spray pattern with allows for numerous cleaning options during different cleaning protocols. The spray patterns herein, whether wide- angle, narrow-angle or another, refer to the distribution of liquid emitted from each of the plurality of spray nozzles 16. Generally, a wide-angle spray pattern disperses liquid over a broader area of the surface 22, e.g. with a spray angle greater than 90 degrees and produces smaller droplets due to the higher dispersion. In some embodiments, a wide-angle spray pattern can be defined as having has a spray angle of from about 60 to about 160°, or about 90 to about 140°. Generally, a narrow-angle spray pattern focuses liquid into a more concentrated area (e.g. a zone or a target area) of the sensor surface, e.g. with a spray angle less than 90 degrees. In some embodiments, a narrowangle spray pattern can be defined as having has a spray angle of from about 0 to about 90°, or from about 0 to about 40°.

[0080] Generally, the plurality of spray nozzles 16 are aimed to optimize the spray pattern in specific zones of the sensor, to provide effective and efficient cleaning of the sensor surface. For example, in one embodiment, an emitting area of the sensor may not be as important and has one optimized spray nozzle aimed at or dedicated to that area. However, a receiving area of the sensor may be more important and could have two optimized spray nozzles aimed at or dedicated to that “target area” on the surface 22 of the sensor 20.

[0081] In some embodiments, the one or more of the plurality of spray nozzles 16 is selected from but not limited to: a static fan spray nozzle; a jet spray nozzle comprising a jet-producing outlet configured to produce a static jet spray pattern; an oscillating fan spray nozzle configured to produce an oscillating fan spray pattern; a combination spray nozzle configured to produce a fan jet and a point jet spray pattern; and a blended jet spray nozzle configured to produce a blended jet spray pattern.

[0082] In some embodiments, one or more of the plurality of spray nozzles 16 is a static fan spray pattern nozzle comprising a fan-producing outlet configured to produce a static fan spray pattern. If included, the static fan spray pattern nozzle is designed to produce a wide-angle spray pattern. In many embodiments, a static fan spray nozzle features a flat orifice with precision-engineered slots or holes that emit a fan-shaped spray pattern through which the cleaning fluid passes through. This design allows for efficient coverage of a broad area, making it ideal for dispersing cleaning fluid over the surface 22 of the sensor 20 as cleaning fluid is uniformly distributed to optimize cleaning fluid distribution.

[0083] In some embodiments, one or more of the plurality of spray nozzles 16 is the oscillating fan spray nozzle. The oscillating fan spray nozzle is designed to create a wide and even spray pattern by oscillating or rotating. In many embodiments, the oscillating fan spray nozzle is equipped with a mechanism that causes them to move back and forth or rotate while spraying to distribute the cleaning fluid evenly over the surface or a portion of the surface. The oscillating fan spray nozzle typically produces, a wide spray pattern, an adjustable range an area, and an even cleaning fluid distribution.

[0084] In some embodiments, one or more of the plurality of spray nozzles 16 is a jet spray nozzle. If included, the jet spray nozzle is used to create a high-velocity stream of cleaning fluid. The design of the jet spray nozzle allows conversion of the potential energy of the pressurized cleaning fluid into kinetic energy, resulting in a concentrated and forceful stream. Which can be used to specifically target debris on the surface or even clean a particularly important portion or “target area” of the surface. If used, various types of jet spray nozzle can be used, including, but not limited to a flat fan nozzle, a full cone nozzle, a hollow cone nozzle, a solid stream nozzle, an air atomizing nozzle, and a rotating nozzle.

[0085] In some embodiments, one or more of the plurality of spray nozzles 16 is a combination spray nozzle configured to produce a fan jet and a point jet spray pattern. The combination nozzle allows a switch between different spray patterns according to specific needs without having to change the entire nozzle assembly. The combination spray nozzle produces both a wide, flat spray that covers a larger area and a concentrated stream of cleaning fluid aimed at a specific point or area. In a typical embodiment, the combination spray nozzle is equipped with a switching mechanism involving adjusting the internal components of the nozzle or using an external control mechanism. In some embodiments, the combination nozzle allows for adjustment of spray angle, flow rate, and spray intensity for each spray pattern.

[0086] In some embodiments, one or more of the plurality of spray nozzles 16 is a blended jet spray nozzle. The blended jet spray nozzle is designed to mix and disperse two or more cleaning fluids into a single spray. This mixing can involve different liquids or a liquid and a gas. The blended jet spray nozzle ensures that the cleaning fluids are blended together before being expelled as a fine, uniform spray. In a typical embodiment, the blended jet spray nozzle comprises internal components that facilitate the thorough mixing of the cleaning fluids and produce a consistent and uniform spray pattern to achieve precise cleaning fluid coverage and distribution. The blended jet spray nozzle can come in various designs and include different spray patterns (e.g., flat fan, full cone, hollow cone) and flow rates.

[0087] In some embodiments, one or more of the plurality of spray nozzles 16 is a dual layer spray nozzle. The dual layer spray nozzle produces two distinct layers or patterns of spray. In some embodiments, the dual layer spray nozzle provides precise control over the spray, good surface coverage, and reduced drift of cleaning fluid.

[0088] In some embodiments, one or more of the plurality of spray nozzles is a dual fluid spray nozzle configured to spray two types of fluid. In many such embodiments a secondary fluid conduit or supply line is required.

[0089] In some embodiments, one or more of the plurality of spray nozzles 16 includes: a heatable nozzle assembly configured to heat a body of the heatable spray nozzle to produce heated fluid in a desired spray pattern; a telescopic nozzle assembly; and/or a dual layer spray nozzle assembly. Heated, telescopic, and dual layer nozzle assemblies may be compatible with different types of nozzles, such as spray described above. For example, the static fan spray nozzle; the jet spray nozzle; the oscillating fan spray nozzle; and the combination spray nozzle can have a heated, telescopic, and/or dual layer nozzle assembly.

[0090] In one embodiment, one or more of the plurality of spray nozzles 16 is a heatable spray nozzle assembly configured to heat the cleaning fluid to spray heated cleaning fluid in a desired spray pattern. In a typical embodiment, the heated spray nozzle comprises a heating element to warm the cleaning fluid before it is sprayed. In some embodiments, one or more of the plurality of spray nozzles is a telescopic nozzle assembly. The telescopic nozzle assembly allows for adjustable length or extension. The telescopic nozzle allows for variance of the distance between the nozzle outlet and the surface. In many embodiments, the telescopic nozzle comprises multiple sections that can slide into one another, similar to a telescope, which allows the length of the nozzle to be adjusted. By extending or retracting the sections, a distance between the nozzle and the surface or debris target on the surface can be changed or adjusted. This adjustability enables changes in spray coverage and intensity. It should be appreciated that the nozzles described herein can, in certain embodiments, have a telescopic nozzle assembly.

With continued reference to Figure 4, nozzle B is proximally (centrally) positioned and utilizes a less-aggressive wide angle to clean the entire surface. In this example, spray nozzle B is positioned for light, general cleaning. Accordingly, in a non-limiting example, spray nozzle B could be the static fan spray nozzle or the oscillating fan spray nozzle.

[00105] Referring now to Figure 18, a method of cleaning a sensor with a cleaning system is also disclosed at 1800. The method can utilize any of the embodiments of the cleaning system described above. The sensor has a surface comprising at least one zone. The cleaning system comprises a plurality of spray nozzles adapted to spray cleaning fluid onto the sensor. The cleaning system also comprises e-valves or fluid pumps in electronic communication with a body control module (“BCM”). The e-valves or fluid pumps are adapted to deliver cleaning fluid from a fluid conduit to the one or more of the plurality of spray nozzles. The method comprising the steps of:

- 2 - • detecting a debris deposit including but not limited to dirt, dust, mud, water, bug protein, ice, and frost on the surface of the sensor 1802;

• determining a response to clean the debris deposit 1804; and

• selectively activating one or more of the plurality of spray nozzles in accordance with the response to spray the surface and remove the debris deposit 1806.

[00106] The first step of the method disclosed includes detection or identification of the debris deposit. In a typical embodiment, the sensor, which is in electronic communication with the BCM, detects the presence and position of the debris deposit on the surface. In turn, the BCM can activate a response, or a cleaning protocol based on the position of the debris deposit. To this end, in one embodiment, the method further comprises the step of determining a location of the debris deposit or a zone or zones on the sensor that the debris deposit is located in.

[00107] For example, a debris deposit could be detected in the first zone. In turn, the step of determining a response could include election of a first response protocol including the sequential activation of nozzle A and nozzle B to remove the debris deposit. As another example, a debris deposit could be detected on the first target area. In turn, the step of determining a response could include election of a first response protocol including the sequential activation of nozzle A and nozzle B to remove the debris deposit.

[00108] In one embodiment, the method further comprises the step of determining whether or not the debris deposit was removed during the step of activating one or more of the plurality of spray nozzles and, if not, determining an additional response to clean the debris deposit and selectively activating one or more of the plurality of spray nozzles in accordance with the additional response to remove the debris deposit. In the current example, if the debris deposit is not removed via the response, an additional response could be the sequential activation of nozzle module D, nozzle module A, and nozzle module B. As such, the additional response could be the sequential activation of nozzle module D, nozzle module A, and Nozzle Module B to make sure the deposit is finally removed. In one embodiment, such as the embodiment of this example, the additional response is with a different spray pattern (and a different response protocol). [00109] In one embodiment of the method, a specific portion of the plurality of spray nozzles is positioned to selectively clean each of at least one zone and the step of selectively activating is further defined as activating the specific portion of the plurality of spray nozzles positioned to clean the zone or zones the debris deposit is located on. In the example at hand, the first response involves selective application of nozzles A and B (a portion being two of the seven nozzles) to clean the debris deposit. In the subject example, the additional response involves selective activation of nozzle module D, nozzle module A, and Nozzle Module B to clean the debris deposit (a portion being three of the seven nozzles). In a typical embodiment, a cleaning protocol including the activation of particular spray nozzles for a particular amount of time, in a particular order could be determined by a vehicle manufacturer, integrator, or sensor manufacturer. Various cleaning protocols that would be needed to for cleaning certain zones or target areas on the sensor could be determined by and saved in a location such as the BCM as determined by the vehicle manufacturer, integrator, or sensor manufacturer.

[00110] In one embodiment, the step of selectively activating one or more of the plurality of spray nozzles in accordance with the response to remove the debris deposit includes spraying the zone the debris deposit is located in with two different spray patterns or two different spray nozzles. In the subject example, the first response involves selective application of nozzles A and B (two different spray patterns) to clean the debris deposit and the additional response involves selective activation of nozzle module D, nozzle module A, and Nozzle Module B to clean the debris deposit (three different spray patterns).

[00111] Of course, in some embodiments of the method, the method comprises the step of detecting a debris deposit, determining a response to clean the debris deposit, and selectively activating one or more of the plurality of spray nozzles in accordance with the response to spray the surface and remove the debris deposit with a single spray nozzle. For example, a debris deposit could be detected in the first target area of the first zone and the response could include election and activation of nozzle module D to remove the debris deposit. This response being an efficient and minimizing cleaning fluid and power use. The cleaning system is flexible, which provides a method that allows a user to tailor a response to a particular zone or target area with a wide array of response options. To this end, it should be appreciated that the method is not limited to the examples described above.
