Description

The invention relates to the automotive industry, namely to lighting systems for predominantly intelligent automatic "unmanned" vehicles, which increase the safety of their movement both in traffic conditions in conjunction with vehicles controlled by drivers, and in conditions of possible proximity to people or animals. The invention can be used for the delivery of goods in hard-to-reach places and (or) in off-road conditions in places where people may not expect the appearance of moving objects - in fields, forests, mountains, and not be prepared for the potential danger of being in the path of a moving unmanned vehicle , especially during the dark time of the day, such as a moonless and starless night. The lighting system can also be used on public roads, both in addition to the traditional lighting system, containing position, running lights and dipped and main beam headlights, or independently, subject to prior approval. Also, the lighting system can be used on trailers.

A lighting system for an autonomous working machine Honda3E-D18 is known, which is an autonomous mobile platform suitable for various purposes by selecting appropriate attachments, equipped with low power low-power running lights (https://global.honda/innovation/CES/2019/autonomouswork_vehicle. html).

However, such a system gives an insufficient idea of the dimensions of the machine in the absence of additional lighting.

A known system for lighting and viewing the path and the surrounding area in front of the vehicle, containing an infrared light source made using a repetitively pulsed semiconductor emitter, a display, a video camera installed in conjunction with an image intensifier tube, an electronic gating system and an automated range scanning unit, coupled with an electronic strobe system (Utility model patent RU 89039, B60Q 1/20, 11/27/2009).

The lighting system ensures safe driving of vehicles and reduces the likelihood of accidents in conditions of limited atmospheric transparency (fog, rain, snow, etc.), especially in low light conditions (dark hours), but does not make the vehicle more visible to other road users.

A headlight system for a vehicle is also known, comprising right and left headlight units and a control device. This system of headlights allows for the possibility of horizontal rotation relative to each other of the optical axes of the headlight units, which ensures good visibility of the road lying in front of the vehicle and at the same time effectively prevents dazzling of other road users (Patent for invention RU 2475382 B60Q 1/14, 29.10.2009) .

However, such a headlight system has the complexity of the device.

There is also known a lighting system for the outer area of a vehicle, comprising photoluminescent parts located on the rear spoiler of the vehicle, and a light source. Photoluminescent parts illuminate various areas around the vehicle, thereby improving the quality of local lighting 145, 08/03/2017).

The disadvantage of such a lighting system for a vehicle is the insufficient visibility of the vehicle, due to the fact that the road surface located under the vehicle is illuminated, which makes this vehicle poorly visible from afar.

The closest analogue is a vehicle lighting system containing a light source directed to the downward-facing lower part of the vehicle surface, containing a door section additionally covered with photoluminescent material (Patent for invention RU 2675768, B60Q 3/00, 02.07.2014).

However, such a lighting system provides inadequate illumination of the vehicle, especially while it is in motion.

The problem to which the invention is directed is the creation of a lighting system for an unmanned vehicle, which makes it more visible in the dark or fog and other atmospheric phenomena that impair visibility in the absence of other lighting, while not blinding people and (or) animals. forward light, and increasing the safety of the unmanned vehicle.

The technical result is to increase the visibility of an unmanned vehicle by illuminating the surface of its body.

The problem is solved and the technical result is achieved due to the fact that in the lighting system of an unmanned vehicle that includes at least one light source directed to the outer surface of the vehicle body, the light source is placed on a console mounted on the vehicle body and protruding beyond its dimensions in front side, and is directed to the front side of the body, mainly to its upper part. In the preferred embodiment, the light source is made in the form of a LED lamp with a directed semi-wide light intensity curve, the console is placed on the longitudinal axis of the vehicle, and the length of the console with the light source on it is 0.15-0.20 of the vehicle width. Alternatively, in the preferred embodiment, the light source can be made in the form of an LED lamp with a directed wide light intensity curve, the console is placed on the longitudinal axis of the vehicle, and the length of the console with the light source on it, respectively, is 0.07-0.10 of the vehicle width . The lighting system of the unmanned vehicle may include a second light source mounted on the second console, while the consoles are located on opposite sides of the longitudinal axis of the vehicle body, offset to the sides of the vehicle body and the light source is directed mainly to the same half of the front side of the body . In this case, the consoles can be shifted to the sides of the vehicle body, and the light source is placed at the corner between the front and side sides of the vehicle body with the possibility of directing the light source both to the front side and partially to the adjacent side of the vehicle body. . To do this, the light source must be placed at the angle between the front and side sides of the body with a gap that is 0.05-0.1 of the longitudinal dimension of the light source. The light source can be made extended and placed parallel to the surface of the front side of the body. The console of the lighting system of the unmanned vehicle can be made in the form of a bracket fixed on the front side of the body. Also, the console of the lighting system of an unmanned vehicle can be made in the form of a beam fixed on the roof of the body.

Placing the light source on a console mounted on the vehicle body and protruding beyond its dimensions to the front side, and directing it to the front side of the body, mainly to its upper part, makes it possible to illuminate its front side in the direction of travel, from which the vehicle carries the greatest potential danger to others, and its most visible, upper part. Placing the light source against the top of the front side of its body and directing the light to its upper part is most advisable, since the upper part of the body surface is visible from a greater distance than the lower one, which can be obstructed by uneven terrain, bushes, grass, and the vehicle becomes visible on greater distance. Placing the light source on the console allows you to move it away from the illuminated surface and illuminate the maximum surface area. The location of the console in the front of the body at the same time allows you to position it without going beyond the side clearance of the vehicle. Implementation of the light source in the form of an LED lamp with a directional semi-wide luminous intensity curve installed on a console located on the longitudinal axis of the vehicle, the length of which with the light source on it is 0.15-0.20 of the width of the vehicle, with a directional wide flux obtained light illuminating the entire front side of the body. It is also possible to obtain a directed wide stream of light illuminating the entire front side of the body by making the light source in the form of an LED lamp with a directed wide light intensity curve, the console is placed on the longitudinal axis of the vehicle, and the length of the console with the light source on it, respectively, is 0.07- 0.10 of the vehicle width. Supplying the lighting system of an unmanned vehicle with a second light source mounted on the second console, with the consoles located on opposite sides of the longitudinal axis of the vehicle body, with an offset to the sides of the vehicle body and the direction of the light source mainly on one half of the side of the body, allows you to emphasize side dimension of the vehicle. Placing the light source at the corner between the front and side sides of the vehicle body with the possibility of directing the light source both to the front side of the direction of the light source both to the front side and partially to the side side of the vehicle body adjoining it will better convey the volume of the vehicle, including including the longitudinal dimension of a moving vehicle, which helps to improve its visibility. Placement of the light source at the corner between the front and side sides of the body with a minimum gap, which is 0.05-0.1 of the longitudinal dimension of the light source, allows you to illuminate both sides of the body at the same time, but at the same time slightly protrude beyond the dimensions of the vehicle. The implementation of the light source extended and placed parallel to the surface of the front side of the body contributes to a better perception of its dimensions. Implementation of the console of the lighting system of an unmanned vehicle in the form of a bracket fixed on the front side of the body or in the form of a beam fixed on the roof of the body - variants of its execution.

Как вариант в предпочтительном варианте источник света 1 может быть выполнен в виде светодиодной лампы с направленной широкой кривой силы света, консоль 2 размещена на продольной оси транспортного средства, а длина

консоли 2 с источником света на ней соответственно составляет 0,07-0,10 от ширины В транспортного средства. Система освещения беспилотного транспортного средства может включать второй источник света 1, установленный на второй консоли 2, при этом консоли 2 расположены по разные стороны от продольной оси кузова транспортного средства, со смещением к краям 5 передней стороны 4 кузова 3 транспортного средства и направлением источника света 1 преимущественно на одну половину передней стороны 4 кузова 3 (Фиг. 4, 5, 6). Источник света 1 может быть размещен на углу между передней и боковой сторонами кузова транспортного средства с возможностью направления источника света 1 как на переднюю сторону 4, так и частично на граничащую с ней боковую сторону 6 кузова 3 транспортного средства (Фиг. 7-11). Для этого источник света должен быть размещен на углу между передней 4 и боковой 6 сторонами кузова 3 с зазором, который составляет 0,05-0,1 от продольного габарита источника света 1. Источник света 1 может быть выполнен протяженным, ориентированы вертикально и размещенным на консолях 2 по краям передней стороны 4 кузова 3 беспилотного транспортного средства параллельно поверхности передней стороны 4 кузова 3 (Фиг. 7-11). Консоль 2 системы освещения беспилотного транспортного средства может быть выполнена в виде кронштейна, закрепленного на передней стороне 4 кузова 3. (Фиг. 4, 5, 6). Также консоль 2 системы освещения беспилотного транспортного средства может быть выполнена в виде балки, закрепленной на крыше 7 кузова 3 (Фиг. 1, 2, 3, 7-11). Оборудованное системой освещения транспортное средство оснащают автоматизированной системой навигационного контроля и управления транспортом, например, с использованием спутниковой системы навигации ГЛОНАСС/GPS и участие в его движении водителя не предусмотрено. Транспортное средство содержит двигатель, систему его запуска и соединенную с системой запуска систему освещения. Система освещения может быть оснащена датчиком света, реагирующим на достаточное внешнее освещение, например, на яркий солнечный свет.The lighting system of the unmanned vehicle includes at least one light source 1 placed on the console 2 mounted on the body 3 of the vehicle. (Fig. 1, 2, 3). The console 2 protrudes from the dimensions of the vehicle in the front side, and the light source 1 is directed to the front side 4 of the body 3 back, mainly on its upper part. Since the directional light sources 1 are directed backwards, their back side is directed forward. In a preferred embodiment, the light source 1 is in the form of a LED lamp with a directional semi-broad luminous intensity curve. In this case, the console 2 is placed on the longitudinal axis of the vehicle, and the length

console 2 with light source 1 on it is 0.15-0.20 of the width B of the vehicle. Alternatively, in the preferred embodiment, the light source 1 can be made in the form of a LED lamp with a directed wide light intensity curve, the console 2 is placed on the longitudinal axis of the vehicle, and the length

console 2 with a light source on it, respectively, is 0.07-0.10 of the width B of the vehicle. The lighting system of the unmanned vehicle may include a second light source 1 mounted on the second console 2, while the consoles 2 are located on opposite sides of the longitudinal axis of the vehicle body, offset to the edges 5 of the front side 4 of the vehicle body 3 and the direction of the light source 1 mainly on one half of the front side 4 of the body 3 (Fig. 4, 5, 6). The light source 1 can be placed at the corner between the front and side sides of the vehicle body with the possibility of directing the light source 1 both to the front side 4 and partially to the side side 6 of the vehicle body 3 adjacent to it (Fig. 7-11). To do this, the light source must be placed at the angle between the front 4 and side 6 sides of the body 3 with a gap that is 0.05-0.1 of the longitudinal dimension of the light source 1. The light source 1 can be made extended, oriented vertically and placed on consoles 2 along the edges of the front side 4 of the body 3 of the unmanned vehicle parallel to the surface of the front side 4 of the body 3 (Fig. 7-11). The console 2 of the unmanned vehicle lighting system can be made in the form of a bracket fixed on the front side 4 of the body 3. (Fig. 4, 5, 6). Also, the console 2 of the lighting system of the unmanned vehicle can be made in the form of a beam fixed on the roof 7 of the body 3 (Fig. 1, 2, 3, 7-11). A vehicle equipped with a lighting system is equipped with an automated navigation control and transport management system, for example, using the GLONASS/GPS satellite navigation system, and the driver is not involved in its movement. The vehicle contains an engine, its start-up system and a lighting system connected to the start-up system. The lighting system can be equipped with a light sensor that reacts to sufficient ambient light, such as bright sunlight.

из геометрических соображений должна составлятьThe lighting system of an unmanned vehicle works as follows. The vehicle moves under the control of an automated navigation control and transport management system, for example, using the GLONASS/GPS satellite navigation system, without the participation of the driver in its control. Therefore, it is not necessary to equip the vehicle with headlights to illuminate the road in front of it for better visibility of the road from the cab. However, the vehicle designation function remains necessary. An unmanned vehicle should be clearly visible on the road at night and in dark areas (for example, under unlit flyovers, bridges) so as not to pose a danger to other vehicles and possible pedestrians in its path due to its invisibility. The light source 1, placed on the console 2, mounted on the body 3 of the vehicle opposite its front side 4 and directed at it, illuminates this front side 4 of the body 3, from which the vehicle carries the greatest potential danger to those who find themselves in the zone of its movement and in close proximity to people and animals. Since there is no driver in the vehicle, he will not be blinded by his own headlights directed to the front part 4 of the body 3, where the windshield is located on manned vehicles. Fixing the console 3 with the light source 1 on the front side 4 of the body 2 or the roof 6 of the unmanned vehicle ensures the preservation of the side clearance of the vehicle. The direction of the light source 1, mainly on its upper part of the front side of the surface 4 of the body 3 provides maximum visibility of the luminous front side of the vehicle body, since the upper part of the body is visible at a greater distance than the lower one, which, moreover, can be covered by vehicles moving in front, as well as, for example, grass when driving off-road. Since the directional light sources 1 are directed backwards and their backs are directed forward, the light source is less prone to pollution, and therefore, the process of reducing the light flux over time will be slowed down. Dirt deposited on the front side of the body will have little effect on the luminosity of the body surface, since this layer of dirt will then glow with reflected light. Placing the light source 1 on the console 2, mounted on the body 3 of the vehicle and protruding beyond its dimensions in the front side, allows you to move it away from the illuminated surface and illuminate it with a stream of light with minimum angles of incidence, thereby ensuring the maximum reflected stream of light with a maximum coefficient reflection, the value of which, in the general case, depends on the angle of incidence. At an angle of divergence of light intensity α to provide illumination of the front surface of the vehicle body over its entire width B, the length of the console

from geometrical considerations should be

Технические требования и методы определения) длина консоли должна составлятьIn the case of a light source in the form of an LED lamp with a directional semi-wide light intensity curve (Technical characteristics of LED light sources, https://system-pe.fosite.ru/wiki), having a divergence angle of light intensity within α=70°, the length of the console 2

or with a vehicle width B not exceeding 2.55 m (GOST 33987-2016 Wheeled vehicles. Masses and dimensions. Technical requirements and methods of determination), the length of the console must be

часть светового потока от источника света будет направлена мимо кузова и не будет его освещать.At

part of the front side of the body surface will not be illuminated. At

part of the light flux from the light source will be directed past the body and will not illuminate it.

Similarly, when the light source 1 is made in the form of an LED lamp with a directed wide light intensity curve (α=80°), the length of the console 2 with the light source on it, placed on the longitudinal axis of the vehicle, respectively, is

Or with vehicle width B not exceeding 2.55 m

The inclusion in the lighting system of the unmanned vehicle of the second light source 1, mounted on the second console 2, located on opposite sides of the longitudinal axis of the vehicle body allows you to direct the light sources each to one half of the front surface of the vehicle body, allows you to emphasize the side dimension of the vehicle. Placing the light source 1 at the corner between the front and side sides of the body allows you to direct the light source 1 on the console 3 both to the front 2 and side 5 sides and illuminate the side of the body with the same light source as the front (Fig. 7-11 ). Illumination of the side surface, which has a large area, will better convey the volume of the vehicle, including its longitudinal dimension, which helps to improve its visibility on the bends of the trajectory. The minimum gap δ, which is 0.05-0.1 of the longitudinal dimension of the light source b, allows you to simultaneously illuminate two sides of the body, but at the same time not lean against the surface of the body and slightly protrude beyond the dimensions of the vehicle. The implementation of the light source 1 extended and placed parallel to the surface of the front side of the body 3 allows you to more evenly illuminate a large area of the front side of the body 3 and makes the vehicle even more visible. Maintenance of the lamp is carried out from the rear side of the light source 1, access to which is completely free. A computer simulation of the operation of the proposed lighting system for an unmanned vehicle has been carried out. In FIG. Figure 12 shows the results of modeling the illumination of an unmanned vehicle with a frontal cross-sectional area B * H = 500 * 600 mm with two extended LED lamps with a brightness of 1000 lm, lamp power - 5 W, placed on console 2 with a minimum gap δ, which is 0.05-0 ,1 from the longitudinal dimension of the light source b. Execution of the console 2 of the lighting system of an unmanned vehicle in the form of a bracket (Fig. 4, 5, 6) fixed on the front side 4 of the body 3 or in the form of a beam fixed on the roof 6 of the body 3 - variants of its execution (Fig. 1, 2, 3). Lighting is turned on automatically when the engine is started, and turned off when the engine is stopped. If the lighting system is equipped with a light sensor that reacts to sufficient ambient light, the lighting system may not turn on in bright daylight conditions.

The use of this invention improves the safety of an unmanned vehicle by increasing its visibility in the dark or fog and other atmospheric phenomena that impair visibility. The use of the proposed lighting system for an unmanned vehicle makes it possible to illuminate a large area of the vehicle (its entire front side in the direction of travel), which makes it clearly visible and gives the greatest idea of its shape and size, and thereby increase the safety of the unmanned vehicle for by increasing its visibility in the dark or fog and other atmospheric phenomena that impair visibility. However, this lighting system does not produce forward light, which eliminates glare to pedestrians and pets and wildlife. A vehicle lighting system that differs from the traditional one used in both manned and unmanned vehicles on the roads will also help bystanders to appreciate that an unmanned vehicle is in front of him.

The lighting system for an unmanned vehicle was developed at the technical proposal stage.
