Abstract

The invention belongs to the technical field of automobile electronics and mainly solves the problem of how to achieve the best lighting effect when a vehicle travels on a bend. A multi-information fusion self-adaptive headlamp system comprises a switch signal sensor, a steering wheel angle sensor, a vehicle speed sensor, a vehicle-mounted GPS, a high-accuracy map, a vehicle-mounted power source,a drive motor position correction module, a self-adaptive headlamp controller, a vehicle lamp reset mechanical structure, a right lamp motor drive module, a right lamp drive motor, a left lamp motor drive module, a left lamp drive motor, a detection protection module and a fault warning module. The system mainly has the two beneficial effects that firstly, the influence caused by the road condition and the curvature change difference on a vehicle lamp steering model can be avoided; and secondly, through judgment of the vehicle advancing direction and establishment of the vehicle lamp steeringmodel, vehicle lamps are controlled to steer through the stepping motors, the best effect of vehicle lamp bend lighting is achieved, and a good lighting environment is better provided for a driver.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and in particular relates to an adaptive headlight system which integrates GPS and high-precision map information. Background technique [0002] With the rapid development of automobile technology, road traffic presents a trend of high speed, non-professional drivers and dense traffic flow. Frequent traffic accidents, heavy casualties and huge property losses make automobile safety a social problem. Statistics show that more than 80% of traffic accidents occur in darkness and bad weather, about 70% of car-people collisions occur at night, and the death rate of car accidents at night exceeds 40%. The adaptive headlight system consists of a speed sensor installed on the vehicle body, a steering wheel angle sensor, an inclination sensor, an electronic control unit and an execution system. The sensor is used to collect the running state of the vehicle. The electronic control unit cal...
