Result when automobile is calculated having driven on uphill way, then generation downwards regulation headlight light so that headlight light
Recover the light height regulating command of the height to automobile normal running when in smooth road conditions, upper and lower dimming unit 400 receives
And in response to the light height regulating command, enable to travel on the automobile headlamp light on uphill way and effectively illuminate upward trend
Section.When Po Lu sections are descending section, before automobile reaches descending section, control unit 300 is according to being calculated down
The gradient angle and automobile in slope section generate apart from the distance in descending section and adjust headlight light downwards to reduce headlight light
The light height regulating command of height, upper and lower dimming unit 400 receive and respond to the light height regulating command, reduce headlight
The height of light, so as to dazzling, the guarantee driving safety of opposite upward slope vehicle for preventing from headlight light from causing travelling in opposite directions；Work as control
Automobile is calculated according to the result of processing unit 200 in unit 300 processed when having driven on descending section, then generation is upward
Headlight light is adjusted so that the light that headlight light recovers height when in smooth road conditions to automobile normal running is highly adjusted
Instruction, upper and lower dimming unit 400 receives and responds to the light height regulating command, makes the automobile that travels on descending section big
Lamp light can effectively illuminate descending section.
Further, in the present embodiment, the output end of control unit 300 is used in running car to apart from domatic road conditions
Start to descend dimming unit 400 to send light height regulating command upwards during the pre-determined distance of Po Lu sections, i.e. when control unit 300
It is calculated when the distance between automobile and Po Lu sections are a pre-determined distance according to the result of processing unit 200 and is just started
Dimming unit 400 carries out dynamic regulation to the height of headlight light up and down for control.The pre-determined distance makes the Po Lu roads of domatic road conditions
Section is within the illumination range region of headlight light, and the spacing distance between Po Lu sections and automobile is that driver leaves foot
Enough reaction actuation times.Preferably, the pre-determined distance is not less than 50m.
Further, the laser radar 100 in the present embodiment enters to the road surface in vehicle front 50m-200m preset range
Row scanning.When road gradient situation is domatic road conditions, the output end of control unit 300 is in running car to apart from domatic road conditions
Po Lu sections 50m pre-determined distance when start to send light height regulating command to headlight.
Based on the above-mentioned automobile light-modulating system based on laser radar detection road surface climb and fall, the present embodiment additionally provides one kind
Automobile light-modulating method based on laser radar detection road surface climb and fall.As shown in figure 1, the automobile light-modulating method of the present embodiment includes

Automobile is calculated according to the result of processing unit 200 in unit 300 when having driven on uphill way, then generates to downward
Section headlight light is so that the light that headlight light recovers height when in smooth road conditions to automobile normal running is highly adjusted and referred to
Order.When Po Lu sections are descending section, before automobile reaches descending section, control unit 300 is according to being calculated down
The gradient angle and automobile in slope section generate apart from the distance in descending section and adjust headlight light downwards to reduce headlight light
The light height regulating command of height；Gone when automobile is calculated according to the result of processing unit 200 in control unit 300
When sailing on descending section, then generation is adjusted up headlight light so that headlight light recovers to automobile normal running in smooth road
The light height regulating command of height when in condition.
Preferably, control unit 300 running car to apart from the Po Lu sections pre-determined distance of domatic road conditions when start to
Upper and lower dimming unit 400 sends light height regulating command.I.e. control unit 300 is according to the result meter of processing unit 200
The distance between Po Lu sections of automobile and domatic road conditions are calculated, when the automobile that control unit 300 is calculated and domatic road conditions
When the distance between Po Lu sections reach the pre-determined distance, control unit 300 starts to descend dimming unit 400 to send light upwards
Height regulating command, highly to carry out dynamic regulation to headlight light.Preferably, the pre-determined distance is not less than 50m.The present embodiment
In, the pre-determined distance is set to 50m.
Step S4, upper and lower dimming unit 400 receives light height regulating command, and is adjusted in response to the regulating command of light height
