Problems solved by technology

[0003] However, when the vehicle encounters a congested road section or waits for a green light at an intersection, the headlights still maintain the normal driving light intensity, which often interferes with the vision of surrounding vehicles and pedestrians due to the strong light intensity, reducing their responsiveness. There are certain road safety hazards

Abstract

The invention provides a method and a device for controlling the illumination intensity of a vehicle light. The method includes: receiving a gear signal, the gear signal pointing to the current gear of the vehicle; when the gear signal points to the parking / starting gear or neutral gear, obtaining the vehicle speed of the vehicle; when the vehicle speed is less than When the preset value is set, the light intensity value of the headlight of the vehicle is reduced. The acquisition of the gear position and the vehicle speed by the present invention effectively determines the current driving environment of the vehicle (such as congested road sections, traffic light intersections). Reduce the light intensity value of the headlights of the vehicle according to the driving environment, reduce the interference of the headlights on the vision of surrounding vehicles and pedestrians due to the retained light intensity, ensure their response sensitivity when facing other vehicles suddenly starting, etc., and improve road safety.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for controlling the illumination intensity of vehicle lights. Background technique [0002] With the rapid development of science and technology, automobiles have become an indispensable means of transportation in people's lives. With the development of science and technology and people's needs, the technology on the car has also developed by leaps and bounds. Turning on or off the lights according to the driving environment can help the current vehicle to obtain a good driving vision on the one hand; on the other hand, it can be used as an identification mark for the current vehicle , for the surrounding vehicles to better understand the driving environment. Headlight is arranged on the front portion of vehicle, and it mainly plays illumination and signal effect. The light emitted by the headlights can illuminate the road conditions ahead of the vehicle...
