[0038] Furthermore, embodiments of the present invention also provide an electronic device, comprising:

[0039] A computer program for executing the NR-V2X-based cooperative vehicle lighting control method as described above;

[0040] Memory for storing the computer program;

[0041] A processor for running the computer program.

[0042] To illustrate more specifically the embodiments of the present invention: When driving at night, it is common to encounter vehicles in the opposite lane turning on their high beams, causing excessive brightness in the driver's eyes and making it impossible to see the road conditions in front of the vehicle. Even after passing the oncoming vehicle, there is still a brief period of difficulty in seeing the road, which seriously affects driving safety.

[0043] Statistics show that 40% of traffic accidents are caused by high beams at night. Therefore, avoiding the misuse of high beams at night can greatly reduce driving safety hazards.

[0044] In existing technologies, the common method to reduce the misuse of high beams by oncoming vehicles is to have the driver flash their lights or honk their horn to remind the other vehicle to turn off its high beams. As people's awareness of driving safety has improved, most drivers are able to turn off their high beams in time to reduce the impact on other vehicles. However, many drivers still do not turn off their high beams in time, which still poses a significant safety hazard.

[0045] The technical solution involved in this invention uses NR-V2X to enable the vehicle to initiate a request for the other vehicle to turn off its high beams when it is interfered with by the high beams of an oncoming vehicle by continuously flashing its high beams. After receiving the request, the oncoming vehicle turns off its high beams according to the actual situation. After the oncoming vehicle confirms that the interference has been resolved, it automatically restores the high beams.

[0046] It should be noted that V2X and NR-V2X, V2X stands for Vehicle-to-Everything, which includes vehicle-to-vehicle (V2V) communication.

[0047] NR-V2X is used in various communication scenarios, including Vehicle-to-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P), and Vehicle-to-Network (V2N). Based on 5G's New Radio access technology, NR-V2X adds unicast and multicast features compared to the single broadcast function of LTE V2X, offering advantages such as lower latency and higher reliability.

[0048] GNSS refers to the Global Navigation Satellite System, which includes GPS, GLONASS, GALILEO, and BDS. GNSS positioning utilizes observations such as pseudorange, ephemeris, and satellite launch times from a set of satellites, while also requiring knowledge of the user's clock bias. A GNSS is a space-based radio navigation and positioning system that can provide users with all-weather 3D coordinates, velocity, and time information at any location on the Earth's surface or in near-Earth space.

[0049] The BCM (Body Control Module) coordinates the operation of different functions within the vehicle via CAN signals. These include door locks, alarm audible control, interior and exterior lighting, safety functions, windshield wipers, turn indicators, and power management.

[0050] In the implementation of this technical solution, both the main vehicle and the oncoming vehicle need to have the VBOX hardware device shown in the figure above, and support the control application of cooperative high beams.

[0051] The working principle of the main vehicle end is as follows:

[0052] (1) When the main vehicle encounters headlight interference from oncoming vehicles at night, it performs continuous flashing operation. The BCM sends the high beam switch status through the CAN bus.

[0053] (2) The VBOX of the main vehicle detects the headlight switch status through the CAN bus and determines that the headlight is continuously flashing. It also determines whether it is nighttime. If it is nighttime, it initiates the application of switching high beams to oncoming vehicles.

[0054] (3) Obtain information about oncoming vehicles by parsing the BSM (Basic Safety Message) broadcast to all vehicles on the road, and initiate a V2X connection request with the oncoming vehicles.

[0055] (4) After establishing a V2X unicast connection with the oncoming V2X vehicle, obtain the on / off status of the oncoming vehicle's high beams, and when the oncoming vehicle's high beams are on, initiate a request message for the oncoming vehicle to turn off its headlights.

[0056] The working principle of the opposing vehicles is as follows:

[0057] (1) After the vehicle receives the connection request from the master vehicle, it completes the V2X connection.

[0058] (2) VBOX receives the V2X request from the main vehicle to turn off the high beams.

[0059] (3) VBOX determines that the main vehicle is an oncoming vehicle based on the BSM message of the main vehicle and that its own high beams are on. It then sends a signal to turn off the high beams on the CAN bus. The BCM module receives the CAN message to turn off the high beams and executes the action of turning off the high beams.

[0060] (4) The VBOX determines whether the main vehicle has completed the high beam turn-off based on the BSM message of the main vehicle. If the high beam turn-off has been completed and the VBOX has performed the action of turning off the high beam, it sends a CAN message to the CAN bus to turn on the high beam. The BCM module receives the CAN message to turn on the high beam, performs the operation to turn on the high beam, and restores the high beam status.

[0061] In summary, the main inventive points of the technical solutions involved in the embodiments of the present invention are the system principle and hardware prototype for implementing cooperative high beam control, as well as the business process for implementing cooperative high beam control. With the cooperative high beam control device and method, the technical solutions involved in the embodiments of the present invention can automatically turn off the high beams of oncoming vehicles upon request from the driver, thereby reducing visual interference to the driver of the driver vehicle from the high beams of oncoming vehicles and reducing the probability of traffic accidents involving the driver vehicle. Compared with the prior art, this invention has significant technical progress.
