Problems solved by technology

[0006] However, human eyes are also very sensitive to weak light in a dim environment (night), and are slow to respond to strong light even in a particularly bright environment (daytime), so if the vehicle lighting device is in the daytime and If the same brightness is used at night, the eyes will feel tired easily at night and the visibility will be reduced during the day

Abstract

The invention provides a method for controlling headlamp of automobile, which comprises the following steps: (1) sensing the external illuminance of the vehicle; (2) sensing starting state of vehicle braking system; (3) if the vehicle braking system is detected to be started, illuminating by a first lamp according to the predetermined brightness based on the brightness sensed in the first step; (4) sensing the vehicle braking state; (5) sensing the distance between the vehicle and the rear vehicle; (6) judging the stopping state of the vehicle, and the brightness of the first lamp is adjusted to the first brightness for illumination after a preset time, if the distance is in the range of the predetermined distance.

Description

technical field [0001] The invention relates to a control method of a vehicle lighting device, in particular to a control method of a vehicle lighting device that adjusts the brightness of the lighting device in consideration of conditions such as light and shade outside the vehicle, weather and the like. Background technique [0002] A car is a vehicle that transmits the power generated by its own engine to the wheels to transport passengers or goods on the road. A car is mainly divided into a body that forms the appearance and a chassis that organically connects various devices. The chassis includes the main devices such as the automobile engine, transmission device, steering device, shock absorber device and brake device as the driving force. [0003] The engine is the driving force behind the movement of the car. Most automobile engines are four-stroke internal combustion engines. The four-stroke internal combustion engine completes a working cycle by four strokes of ...
