Description

Technical Field

[0001] The present invention relates to the field of automobile V2X interactive control, and in particular to a high beam intelligent interactive control system and method. Background Art

[0002] At present, the high beam of a vehicle is mainly controlled by the owner to turn it on or off independently. A few vehicles can control the high beam to turn it on or off according to the brightness of the surrounding environment. The high beam is controlled independently by the owner, and can only flash its own high beam to remind the driver. It cannot remind the vehicle behind, and the vehicle condition operates independently. A vehicle with automatic high beam can only automatically turn off its own high beam due to the influence of the ambient light. It can only detect the surrounding light environment, with low detection sensitivity, and cannot detect whether the vehicle in front is disturbed. There is no warning or forced control of rear light pollution and forward light pollution, and the vehicles cannot be connected and controlled. Summary of the invention

[0003] The technical problem to be solved by the present invention is to measure the influence of high beam lights on vehicles, exchange information between the front and rear vehicles, and intelligently control the high beam lights.

[0004] The present invention provides a high beam intelligent interactive control system, comprising: Light sensor, used to detect the intensity and duration of light exposure to other vehicles: V2X module, used to receive signals from light sensors and communicate the signals with other vehicles; A CAN transceiver, used to receive instructions from the V2X module and control the high beam of the vehicle through the CAN bus; The central control module is used to receive the instruction from the V2X module and display the request of turning off the high beam of the vehicle.

[0005] Furthermore, the other vehicles include a front vehicle, a rear vehicle and an oncoming vehicle relative to the vehicle.

[0006] Furthermore, the V2X module is used to send instructions to the central control module, and the central control displays a notification, where the notification is to remind the user to turn off the high beam.

[0007] Furthermore, when the light sensor receives a large amount of strong light, it determines the level of the strong light and transmits the level of the strong light to the V2X module of the vehicle.

[0008] Furthermore, the light sensor digitizes the received light intensity through an analog-to-digital converter, and the light intensity levels 0-10 correspond to different parameters. The corresponding parameters are encoded in a format supported by V2X and transmitted to the V2X module.

[0009] Furthermore, there is a common protocol stack between the V2X modules, which previously used a fixed wireless format for data connection and sharing.

[0010] Furthermore, the V2X module is directly connected to the central control, and V2X transmits the received data to the central control, which analyzes the data and prompts the user on the screen if it exceeds a threshold.

[0011] Furthermore, the V2X module is connected to the CAN transceiver. Through the interface protocol, the MCU on the V2X module converts the instruction group packet to turn off the high beam into a CAN signal and sends it to the CAN transceiver. The CAN transceiver receives this information and transmits it to the high beam of the vehicle.

[0012] The present invention provides a method, including the above system, the front vehicle, the rear vehicle or the oncoming vehicle all have the same or similar device, S10, the V2X module of the current vehicle transmits the received strong light level information to the V2X module of the following vehicle via V2X wireless mode, and the V2X module of the following vehicle A sends this information to the central control screen of the following vehicle again, and the central control screen of the following vehicle performs threshold judgment; S20: if the vehicle is not over the limit, no action is taken; if the vehicle is over the limit, the rear vehicle screen prompts the rear vehicle owner to manually turn off the high beam. If the rear vehicle owner turns off the high beam, this process ends; S30, if the owner of the rear vehicle still does not turn off the high beam, the central control screen of the rear vehicle continues to determine whether its prompt has timed out. If the owner still does not turn off the high beam after the timeout, the central control screen of the rear vehicle will send a command to forcefully turn off the high beam to the CAN transceiver of the rear vehicle. The CAN transceiver of the rear vehicle will send the command to turn off the high beam to the CAN bus of the rear vehicle, so that the rear vehicle can turn off the high beam.

[0013] The present invention adds a photosensitive system to the vehicle. The affected vehicle uses a photosensitive processor to intelligently identify the brightness of the high beam and record the duration of the impact. Through the V2X interactive system, the affected vehicle and the vehicle turning on the high beam increase the information interaction between vehicles by introducing V2X technology. The intelligent control system, if the vehicle turning on the high beam continues to affect the affected vehicle, the control system can perform intelligent control of the vehicle's high beam by receiving the impact level, impact duration, etc. transmitted by the affected vehicle. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 It is a system structure diagram of the present invention; Figure 2 is a flow chart of the method of the present invention. Specific implementation methods

[0017] The following describes several preferred embodiments of the present invention with reference to the drawings in the specification, so that the technical content is clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

[0018] The specific implementation methods of the present invention are as follows: Example 1 Figure 1 As shown: A high beam intelligent interactive control system, comprising: Light sensor, used to detect the intensity and duration of light exposure to other vehicles: V2X module, used to receive signals from light sensors and communicate the signals with other vehicles; CAN transceiver, used to receive instructions from the V2X module and control the vehicle's high beam through the CAN bus; The central control module is used to receive instructions from the V2X module and display the vehicle's request to turn off the high beam.

[0019] Other vehicles include the vehicle in front, behind, and oncoming vehicles relative to the vehicle.

[0020] The V2X module is used to send instructions to the central control module, which displays notifications to remind users to turn off the high beam.

[0021] When the light sensor receives a large amount of strong light, it judges the level of the strong light and transmits the level of the strong light to the V2X module of the vehicle.

[0022] The light sensor digitizes the intensity of the received light source through an analog-to-digital converter. The light intensity levels of 0-10 correspond to different parameters. The corresponding parameters are encoded in the format supported by V2X and passed to the V2X module.

[0023] There is a common protocol stack between V2X modules, which previously used a fixed wireless format for data connection and sharing.

[0024] The V2X module is directly connected to the central control system. V2X transmits the received data to the central control system, which analyzes the data and prompts the user on the screen if the data exceeds the threshold.

[0025] The V2X module is connected to the CAN transceiver. Through the interface protocol, the MCU on the V2X module converts the instruction group packet to turn off the high beam into a CAN signal and sends it to the CAN transceiver. The CAN transceiver receives this information and passes it to the high beam of the vehicle. The CAN transceiver interacts with the CAN bus of the vehicle.

[0026] Example 2 Figure 2 As shown: When the strong light from the rear vehicle hits the front vehicle, the V2X module of the front vehicle will transmit the received strong light level information to the V2X module of the rear vehicle via V2X wireless method. The V2X module of the rear vehicle A will send this information to the central control screen of the rear vehicle again, and the central control screen of the rear vehicle will make a threshold judgment. If it does not exceed the standard, no processing will be done. If it does exceed the standard, the owner of the rear vehicle will be prompted on the rear vehicle screen to manually turn off the high beam. If the owner of the rear vehicle turns off the high beam, this process ends. If the owner of the rear vehicle still does not turn off the high beam, the central control screen of the rear vehicle will continue to judge whether its prompt has timed out. If the owner still does not turn off the high beam after the timeout, the central control screen of the rear vehicle will send a command to force the high beam to be turned off to the CAN transceiver of the rear vehicle, and the CAN transceiver of the rear vehicle will send the command to turn off the high beam to the CAN bus of the rear vehicle, so that the rear vehicle will turn off the high beam.

[0027] When the strong light of the oncoming vehicle hits the vehicle in front, the V2X module of the vehicle in front will transmit the received strong light level information to the V2X module of the oncoming vehicle via V2X wireless method. The V2X module of the oncoming vehicle A will send this information to the central control screen of the oncoming vehicle again, and the central control screen of the oncoming vehicle will make a threshold judgment. If it does not exceed the standard, no processing will be done. If it does exceed the standard, the owner of the oncoming vehicle will be prompted on the screen of the oncoming vehicle to manually turn off the high beam. If the owner of the oncoming vehicle turns off the high beam, this process ends. If the owner of the oncoming vehicle still does not turn off the high beam, the central control screen of the oncoming vehicle will continue to judge whether its prompt has timed out. If the owner of the oncoming vehicle still does not turn off the high beam after the timeout, the central control screen of the oncoming vehicle will send the command to force the high beam to be turned off to the CAN transceiver of the oncoming vehicle. The CAN transceiver of the oncoming vehicle will send the command to turn off the high beam to the CAN bus of the oncoming vehicle, so that the oncoming vehicle will turn off the high beam.

[0028] The present invention adds a photosensitive system to the vehicle. The affected vehicle uses a photosensitive processor to intelligently identify the brightness of the high beam and record the duration of the impact. Through the V2X interactive system, the affected vehicle and the vehicle turning on the high beam increase the information interaction between vehicles by introducing V2X technology. The intelligent control system, if the vehicle turning on the high beam continues to affect the affected vehicle, the control system can perform intelligent control of the vehicle's high beam by receiving the impact level, impact duration, etc. transmitted by the affected vehicle.

[0029] The preferred specific embodiments of the present invention are described in detail above. It should be understood that ordinary technicians in the field can make many modifications and changes based on the concept of the present invention without creative work.
