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 an illumination intensity control method and device of a vehicle lamp. The method comprises the following steps: receiving a gear signal, wherein the gear signal is directed toa gear in which a vehicle is currently located; acquiring a vehicle speed of the vehicle when the gear signal is directed to a parking/starting gear or neutral gear; and lowering an illumination intensity value of headlamps of the vehicle when the vehicle speed is less than a preset value. According to the illumination intensity control method and device provided by the invention, by acquiring thegear position and the vehicle speed, the driving environment (such as a traffic jam section and a traffic light intersection) where the vehicle is currently located can be effectively determined. Theillumination intensity value of the headlamps of the vehicle is lowered according to the driving environment, thereby reducing the vision interference of the headlamps to surrounding vehicles and pedestrians due to the retained illumination intensity, ensuring the reaction sensitivity of a driver when other vehicles suddenly start and other situations occur, and improving the 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...
