Automatic vehicle illumination control system and control method

Abstract

The invention discloses an automatic vehicle illumination control system and a control method. The automatic vehicle illumination control system comprises a headlamp controlled by a horizontal drive motor and a vertical drive motor, wherein both the horizontal drive motor and the vertical drive motor are controlled by a control module ECU; the control module ECU is connected with a vehicle speed sensor, a steering wheel angle sensor, a front-wheel vehicle body height sensor and a rear-wheel vehicle body height sensor; the horizontal drive motor and the vertical drive motor are adopted simultaneously, calculation is performed by the control module ECU according to multiple parameters including a brake distance, a vehicle speed, a steering wheel angle, front vehicle body height and rear vehicle body height, comprehensive and accurate control of the headlamp is realized, the accident rate during night driving is reduced greatly, and the driving safety is improved obviously; the system is simple in structure, convenient to mount and low in cost, the sensors have comprehensive functions although only a few sensors are adopted, and the requirements for the headlamp during driving at a curve and on a slope at night can be completely met.

Description

【Technical field】 [0001] The invention belongs to the field of automotive electronic intelligent control, in particular to a vehicle lighting automatic control system and a control method. 【Background technique】 [0002] As the most important active safety equipment in automobiles, the automotive headlamp lighting system has gradually become the focus of research and attention on its improvement and innovative design. [0003] In actual use, the illumination range of the ordinary headlights installed on the car is fixed. When driving on a curve at night, the lighting angle cannot be adjusted, and a "blind spot" often appears on the inside of the curve, and the driver's sight is imprisoned by the headlight beam. Within the straight line range, this is very dangerous for the car to drive on the curve at night, which greatly affects the safety of driving at night. According to statistics, although the traffic volume at night is less than 20% of the traffic volume during the da...

Problems solved by technology

[0005] At present, there are still some deficiencies in the research on the AFS system of automobiles. Most of the researches simply determine the deflection angle of the headlights according to the vehicle speed and steering wheel angle parameters, and the description of the movement characteristics of the headlights is not complete; and Some studies only calculate the horizontal rotation angle of the headlight, and then drive the motor to reach the specified position, so that the headlight cannot rotate vertically when the car goes up and downhill, so that the role of the AFS system cannot be fully utilized
