detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The mobile terminal in the embodiment of the present invention may include a smart phone (such as an Android mobile phone, an iOS mobile phone, a Windows Phone mobile phone, etc.), a tablet computer, a palmtop computer, a notebook computer, a mobile Internet device (MID, Mobile Internet Devices), or a wearable device. It has a camera and an accelerometer for taking pictures and video calls, as well as detecting car speed and direction changes. The above mobile terminal is only an example, not an exhaustive one, including but not limited to the above mobile terminal.

The vehicle-mounted terminal in the embodiment of the present invention may be a central control navigation terminal integrated in the automobile, or may be a terminal external to the automobile, and can control the lighting, the horn, the steering wheel, the brake and the throttle of the automobile.

The terms "first", "second" and "third" and the like in the specification and claims of the present invention and the above drawings are used to distinguish different objects, and are not intended to describe a specific order. Furthermore, the terms "comprises" and "comprising" and "comprising" are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or alternatively Other steps or units inherent to these processes, methods, products or equipment.

1 is a schematic flowchart of a prompting method based on a mobile terminal according to an embodiment of the present invention. In this embodiment, the method includes the following steps:

S101. The mobile terminal initiates a connection request to the in-vehicle terminal, and establishes a connection with the in-vehicle terminal.

Optionally, the mobile terminal and the vehicle terminal can be connected through a USB cable or through the blue Wireless connection such as teeth, wifi or NFC. After the connection, the two can perform control commands and data transmission.

S102: The mobile terminal initiates a connection request to the projection device, and establishes a connection with the projection device. When the user inputs a synchronization display function on command on the mobile terminal, the front camera of the mobile terminal is started; and the user's eye is collected. And generating, in real time, an analog pattern output corresponding to the acquired eye image to the projection device and projecting to the rear windshield of the automobile, the simulation pattern including upper and lower eyelids and coix seed and the upper and lower eyelids following the eyelid of the user, The mobile terminal receives the steering information sent by the vehicle-mounted terminal and correspondingly controls the position of the image of the scorpion projected by the projection device in the simulation pattern when the user changes the steering wheel to a certain angle.

Specifically, the communication means between the currently driving cars is very limited, and can only be simply expressed by the lights and the horns. Not only the content expressed is very limited, but also the timeliness is poor, and the occurrence of traffic accidents is often a momentary event. Before the accident, the cars around the problem vehicle were often unpredictable. For example, if the car does not change the turn signal and suddenly changes lanes, can the car predict in advance? Is the front brake in the normal braking or an emergency in front of the front? After the car unconsciously hit the high beam to interfere with the front car, how to inform the car in the front car? Is the front car tired driving? Demands such as these are not reflected in real time by lights and speakers.

Therefore, in the embodiment, the user's eye image can be captured by the camera of the mobile terminal and a corresponding analog image can be generated and projected onto the rear windshield of the automobile through the projection device. It is recognized by the driver of the following vehicle and can greatly improve the safety performance of the running vehicle. The reason is: human eye changes can transmit a lot of useful information, combined with the driving scene, when the driver wants to turn and change lanes, the pupil of the eye will subconsciously move in the direction to be turned; when the driver is driving fatigue At the time, the eyelids must be enlarged and reduced intermittently. If it is particularly tired, it will maintain a state of micro-closed; the current side has an unexpected situation, the eyes will suddenly enlarge, and the distance between the eyelids will be significantly widened. These eye movements are all human subconscious reactions, so the driver may forget to turn the turn signal, but will not forget to turn the pupil, the accuracy is very high. Moreover, the change of the eye often precedes the change of the action, which can help the surrounding drivers to make judgments in advance and greatly improve the safety factor. In addition, the information of the eyes is often read in an instant, so the information transmission of the eyes is more efficient and direct than the words and pictures. Secondly, the present invention does not require the driver to distract attention to perform any action, and also ensures the safety of the driver itself.

Optionally, the mobile terminal may further receive voice data input by the user, and convert the voice data into text information and send the information to the projection device for text information projection.

The eye information can let the following vehicle real-time information about the driver of the car, but the driver of the car should actively remind the car, and the eyes alone still have certain limitations. For example, if the driver's eye-opening light interferes with the driver's driving, the driver of the car can say "Please turn off the high beam, thank you!", let the voice be converted into text and projected to the rear windshield. I know my mistakes and adjust the lights to improve the safety factor of the car.

Optionally, before converting the voice data into text information and transmitting the text information to the projection device for text information projection, the method further includes:

Extracting keywords in the voice data, and calling a preset statement according to the keyword to send to the projection device for text information projection.

This step is a further improvement of text projection. Because, if the driver of the car is not good at words, converting the original words into text and projecting it to the rear windshield will easily irritate the car and cause unnecessary consequences. Therefore, the voice input by the driver can be processed correspondingly, the keywords are extracted from the utterances, and then the preset civilized terms are matched and projected. Still use the reminder to turn off the flash as an example. The driver of the car may be irritated by the high beam of the rear car, and the vocabulary containing the high beam and the insulting character is included. The mobile terminal recognizes the keyword "high beam" and calls the civilized language "Please turn off the high beam. Light, thank you!" Then send it to the projection device to project out, which can not only accurately remind, but also improve the possibility of the rear driver to close the high beam.

S103. When the user inputs a pre-collision function on command on the mobile terminal, start the rear camera of the mobile terminal to monitor the vehicle in front of the user's car; if the distance between the user's car and the vehicle in front is monitored is less than the first When a preset threshold is used, the user is reminded to pay attention to the following distance; if the distance between the user's car and the preceding vehicle is less than the second preset threshold, the first brake command is sent to the vehicle-mounted terminal to notify the The vehicle terminal presses the brake of the preset depth; if it is monitored that the distance between the user's car and the vehicle in front is less than a third preset threshold and the third preset threshold is close to the minimum braking distance of the user's car at the current speed, then Sending a second brake command to the vehicle-mounted terminal to notify the vehicle-mounted terminal to step on the brake.

The third preset threshold <the second preset threshold <the first preset threshold.

Ranging through the camera of the mobile terminal, and prompting the user to control the distance with the car, at a small distance Direct control of the brakes, so as to avoid rear-end collisions, and through the mobile terminal, without increasing the cost of the car.

S104, when the user travels for more than a preset time or when the user inputs an anti-fatigue driving function on command on the mobile terminal, the front camera of the mobile terminal is activated to capture a facial expression of the user; if the current facial expression of the user Matching the expression in the pre-stored fatigue driving expression library, the user is reminded to stop the parking and initiate a video request to the preset terminal so that the user of the preset terminal can view the current facial expression of the user; if the user reminds the mobile terminal After the parking break is still not stopped, the acceleration changes in the left, right and front directions of the user's car are further detected. When the acceleration change amount in the three directions reaches the preset change amount, the The vehicle terminal sends a brake command to notify the vehicle terminal to step on the brake and turn on the danger alarm flash; and dials the preset terminal so that the user of the preset terminal acquires the current physical fatigue condition of the user.

The user's facial expression is captured by the front camera of the mobile terminal, and combined with the preset expression database to determine whether the user is in a fatigue driving state, thereby reminding the user to stop and rest. Therefore, the traffic accident caused by the fatigue driving can be avoided, and the safety of driving is improved. By notifying the third party and controlling the brakes, it is possible to ensure that the fatigued user continues to drive and further ensure the safety of driving.

Alternatively, since a plurality of car users in a home may use one car, or the user lends the car to other friends, the mobile terminal initiates a connection request to the in-vehicle terminal to establish a connection with the in-vehicle terminal. ,Also includes:

Determine the user's identity based on the password entered by the user;

If the current user is different from the user identity of the last time the car was used, the driving data of the user is read according to the determined user identity, and the driving data is stored or uploaded to the cloud server for storage by the mobile terminal; the driving data includes a seat. Adjust data, mirror adjustment data and music type preference data;

The read driving data is transmitted to the in-vehicle terminal to cause the in-vehicle terminal to adjust the seat and the rear view mirror, and to load a corresponding type of music.

Optionally, the password comprises a fingerprint password, an iris password, a digital password or a gesture password.

Through the user identity confirmation, the relevant driving parameters can be adaptively adjusted, and the user can save the data after adjusting once for the next direct use, which is very convenient.

In this embodiment, by connecting the mobile terminal and the vehicle-mounted terminal to form an intelligent driving system, the vehicle with low configuration and simple function can use the camera, the sensor and the processor on the mobile terminal. Function, to achieve the purpose of intelligent driving of the car; by capturing the user's eye image, and projecting the corresponding analog pattern to the rear windshield of the car through the projection device, the rear car can more accurately know the intent and state of the car user. Improve the safety of driving; by detecting the distance from the preceding vehicle and controlling the brakes, pre-crash can be realized to avoid the occurrence of rear-end collisions; by detecting the user's expression and the acceleration of the car, it can be determined whether the user is driving fatigue, and then can be reminded The user stops and even stops the parking and sends the user's situation to the third party, avoiding the accident caused by the fatigue driving, and greatly improving the safety of the driving of the car; by implementing the above functions through the cooperation of the mobile terminal and the vehicle terminal, the cost of the automobile can be greatly reduced.
