Intelligent illuminating system of automobile headlight

Abstract

The invention discloses an intelligent illumination system for automotive headlamp, which comprises a headlamp and an automatic control device, wherein the headlamp includes a light source, a reflector and a lamp body; the automatic control device comprises a speed sensor, a vehicle height sensor, a steering sensor, a control unit, a step motor and a tilting shaft; the step motor is connected with the tilting shaft; the tilting shaft is connected with the reflector; and the action of the step motor makes the optical axis of the reflector adjusted in vertical and horizontal direction through the tilting shaft. The intelligent illumination system of the invention can automatically adjust the headlamp in time according to the change in posture and steering angle of a vehicle, and has the advantages of reasonable design, sensitive response, accurate control, high interference resistance, stable and reliable performance, high environment adaptability, convenient use and maintenance, etc.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to an intelligent lighting system for headlights of automobiles that automatically adjusts headlights up and down, left and right according to vehicle body inclination angle signals and steering signals. Background technique [0002] With the continuous advancement of automobile technology, automobile safety has attracted more and more attention. At present, the headlights of automobiles are all fixed on both sides of the front, and the light of the headlights cannot be adjusted up and down, left and right automatically, and there is a potential safety hazard. When the vehicle accelerates, decelerates, parks, loads and unloads goods, gets on and off passengers, etc., it will cause changes in the front and rear axle loads of the vehicle and change the body posture of the vehicle, and the irradiation height of the headlights cannot be automatically adjusted according to this change. It will ...

AI Technical Summary

Problems solved by technology

At present, the headlights of automobiles are fixed on both sides of the front. The lights of the headlights cannot be automatically adjusted up and down, left and right, and there are potential safety hazards.

When the vehicle accelerates, decelerates, parks, loads and unloads goods, gets on and off passengers, etc., it will cause changes in the front and rear axle loads of the vehicle and change the body posture of the vehicle, and the irradiation height of the headlights cannot be automatically adjusted according to this change. It will affect the road illumination effect of headlights, and even cause glare to oncoming vehicles, affecting driving safety

When the car is going straight at night, the light can still shine on the road in the direction of travel, which can have a good line of sight, but when driving on a curved road, the light deviates from the direction of travel, causing the driver to be unable to see the road clearly, which will also affect driving safety.
