Embodiment Construction

[0038] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0039] Such as figure 1 As shown, the present invention discloses an adaptive automobile headlamp, comprising a headlamp body, a headlamp horizontal steering motor, a headlamp vertical steering motor, a photosensitive sensor, an infrared distance sensor, a steering wheel angle sensor, and a vehicle yaw Angular velocity sensor, vehicle height sensor at the front wheel, vehicle vertical velocity sensor at the front wheel and ECU control module;

[0040] The body height sensor at the front wheel is used to collect the vertical height of the connection between the chassis and the front wheel axle relative to the center of gravity of the car, and the vehicle body vertical speed sensor at the front wheel is used to collect the vertical height of the connection between the chassis and the front wheel axle. speed;

[0041] The photosensitive sensor, the ...

Abstract

The invention discloses an adaptive automobile headlamp and a control method thereof. The adaptive automobile headlamp comprises a headlamp body, a headlamp horizontal steering motor, a headlamp vertical steering motor, a photosensitive sensor, an infrared distance sensor, a steering wheel rotation angle sensor, an automobile yaw angular velocity sensor, a vehicle body height sensor at a front wheel, a front wheel vertical velocity sensor and an ECU (Electronic Control Unit) control module. During work, the ECU control module controls automatic turn-on and turn-off of the headlamp according to the photosensitive sensor, controls automatic switching of high beam and low beam according to a signal of the infrared distance sensor and drives the headlamp horizontal steering motor and the headlamp vertical steering motor according to signals of the steering wheel rotation angle sensor, the automobile yaw angular velocity sensor, the vehicle body height sensor at the front wheel and the front wheel vertical velocity sensor, so that the headlamp irradiates in the special direction when an automobile turns around and climbs or gets down a slope. According to the invention, the blind spot vision of drivers under complex road conditions can be reduced and even eliminated.

Description

technical field [0001] The invention relates to the field of intelligent control of automobile electrical and electronic lighting systems, in particular to an adaptive automobile headlight and a control method thereof. Background technique [0002] With the steady growth of my country's car ownership and the gradual improvement of urban and rural road traffic networks, cars have become more and more popular as a convenient and fast means of transportation, and rely on computer intelligent control technology, especially modern integrated control such as single-chip microcomputers. Cars are also developing in a more intelligent, humane, and safer direction. [0003] Along with the popularization of automobiles, safety accidents are also more and more frequent. Among them, driving safety accidents at night are far more than during the day. The light cannot be switched in time, and the blind area of ​​vision is serious when turning and going up and down slopes. [0004] How to ...
