Specific embodiment
The utility model is directed to a kind of vehicle front lighting light intelligent control system, and solution manually adjusts existing for headlamp
It is cumbersome and there are problems that security risk.
Embodiment:
As shown in Figure 1, the vehicle front lighting light intelligent control system in the present embodiment includes: master controller, battery, preceding photograph
Lamp module, FM-CW radar sensor, starts switch circuit and reset circuit at photorelay；The circuit that starts switch is used for
Vehicle launch signal, triggering master controller work are inputted to master controller after vehicle igniting；The photorelay is for examining
It surveys the variation of external environment light intensity and inputs master controller；The FM-CW radar sensor for detect to always vehicle or with it is same
