Headlamp follow-up control system and method based on steering wheel angle sensor

Abstract

A headlamp follow-up control system based on a steering wheel angle sensor comprises an ECU controller, and the ECU controller is connected with a rotating motor. The ECU controller is connected with the stepping motor; the ECU controller is connected with the steering wheel angle sensor; the ECU controller is connected with the vehicle body attitude sensor; the output ends of the rotating motor and the stepping motor are connected with the headlamp holder; the method of the headlamp follow-up control system comprises the following steps that (1) when a vehicle is detected to run and turn, the inclination angle of a vehicle body is detected through a vehicle body attitude sensor, an electric signal of a steering wheel angle sensor is connected into a follow-up lighting control ECU controller, and the ECU controller controls a rotating motor to adjust the left-right angle of a headlamp; (2) when the vehicle goes uphill, a vehicle body posture sensor converts the inclination angle of the vehicle body into an electric signal, the electric signal is converted into electric energy provided for a stepping motor at a vehicle lamp through an EMC controller, and the illumination angle of the lamp is changed; the lighting range of the vehicle is more comprehensive. The system is more intelligent.

Description

technical field [0001] The invention belongs to the technical field of automobile engineering, and in particular relates to a headlamp follow-up control system based on a steering wheel angle sensor and a method thereof. Background technique [0002] When a car is turning, especially on an urban road without street lights at night, it will affect the driver's judgment on pedestrians or other obstacles on the curve due to the range of exposure of the headlights, resulting in traffic accidents and life and property damage. loss. [0003] Therefore, in order to enable the driver to accurately and timely obtain the lighting information of the road ahead when driving in harsh environments or at night, it is required that the headlight lighting system can continuously adjust the light irradiation angle as the road condition information changes. Light follow-up steering system (Adaptive Front-ligjting System, referred to as AFS). [0004] However, if the headlights can only turn ...

AI Technical Summary

Problems solved by technology

When the vehicle is going downhill, when only the front wheels enter the slope, the light will be higher than the line of sight, resulting in short-distance and road light not being illuminated, making it impossible to judge the detailed conditions of the road surface

Another example: the vehicle body will incline to a certain extent when turning, and this phenomenon is particularly obvious on the slope, which causes certain deviations in the illumination range of the left and right headlights of the vehicle; especially for large trucks, the vehicle body when turning The inclination will be larger, which will cause a lot of trouble to the driver, and accidents will easily occur
