When angle raises up or moves down, ALS meeting adjust automatically optical axis angles, it is to avoid to beam irradiation position when optical axis raises up or be downward-sloping
Influence.Summarizing its effect is exactly:Light is servo-actuated up and down with the change of centre of gravity of vehicle, keeps horizontal irradiation.
Current optical axis automatic adjustment system ALS operation principles are：One height sensor is respectively installed on antero posterior axis,
Automobile accelerates to perceive the difference in height of antero posterior axis during with slowing down, or start climb and fall.Headlamp is controlled with the signal of its difference in height
Optical axis just.Such optical axis automatic adjustment system has a defect, automobile will be gone up a slope or descending could not sensed in advance,
So cannot be to optical axis adjust automatically.Preferable optical axis automatic adjustment system should adjust upward headlamp automatically in fast upward slope
Irradiating angle, the road conditions on slope are seen in advance.Automatically the irradiating angle of headlamp is adjusted when being pushed up to slope downwards, it is to avoid under lamp
It is black.
Current headlight follow-up steering AFS operation principles are：Produced according to velocity sensor and steering wheel angle sensor
Raw GES and steering wheel angle signal, constantly carry out left and right dynamic regulation to headlight, adapt to current steering angle, keep
Light direction is consistent with the current driving direction of automobile, to ensure to provide road ahead optimal illumination and driver is provided most
Good visibility.Such headlight follow-up steering also has a defect, to automobile will enter bend could not sensed in advance, it is necessary to
After automobile enters bend, start steering wheel rotation, steering wheel angle signal could be produced by steering wheel angle sensor, so that
Headlight follow-up steering is controlled by control system.Namely car first turns, and lamp just turns.Preferable headlight slave steering system should
Should be when bend be entered soon, energy sensed in advance accordingly adjusts the left and right irradiating angle of headlamp in advance, sees on bend in advance
Road conditions.
