Embodiment Construction

[0029] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.

[0030] Such as figure 2 As shown, the present invention provides a method for automatically adjusting car lights, including the following steps:

[0031] (1) A G sensor is installed inside the dimming control unit, and the dimming control unit collects and analyzes the axial acceleration and angular velocity data of the vehicle obtained by the G sensor;

[0032] (2) The dimming control unit obtains vehicle information through the body bus, that is, the vehicle speed, gear, accelerator pedal position, and brake pedal position, and identifies the state of the vehicle according to the vehicle information;

[0033] (3) The dimming control unit calculates the current head angle of t...

Abstract

The invention relates to the technical field of automatic adjustment of automobile headlamp low beams and discloses an automobile lamplight automatic adjusting method and system. The automobile lamplight automatic adjusting method includes the following steps that a light adjustment control unit acquires and analyzes axial accelerated speed and angular speed data obtained by a G sensor installed in the light adjustment control unit; the light adjustment control unit obtains automobile information through an automobile body bus and recognizes the state of an automobile; the light adjustment control unit calculates the current automobile head inclination angle of the automobile according to the axial accelerated speed data; and according to the state of the automobile, the light adjustment control unit controls a light adjustment execution mechanism to adjust the irradiation distance of headlamps according to the automobile head inclination angle and selectively according to the angularspeed data. Light adjustment accuracy is high, no external equipment is needed, the cost of the whole system is reduced, the risk that the whole system fails due to the severe use environment of an automobile chassis is avoided, and the maintenance problem of a height sensor is solved.

Description

Technical field [0001] The invention relates to the technical field of automatic adjustment of low beams of automobile headlights, and in particular to a method and system for automatic adjustment of automobile lights. Background technique [0002] The law stipulates that when the brightness of the headlight of the car exceeds 2000lm, a light adjustment device must be installed, through which the adjustment of the low light distance can be realized, and the high low light may cause dazzling to the driver of the vehicle in front. There are two existing dimming methods. One is manual dimming. By installing a dimming button on the front panel of the driver, the driver controls the low beam adjustment within a certain range. This method has low cost, but requires the driver to participate in dimming, and the lights cannot be adjusted according to road conditions during the driving of the car, and the dimming effect is poor. Another dimming method is automatic dimming. A height senso...
