Further, at dimmer control, SW1 is not closed, and passing light is not opened, when car body controller receives the operation signal of distance light switch SW 2 continuously:
If the time gap of continuous handling is less than described setting value, the frequency of car body controller control country beam flicker is identical with setpoint frequency;
If continuous handling interval greater than equaling described setting value, the frequency of car body controller control country beam flicker is identical with the operating frequency of distance light switch SW 2.
Further, described setting value is 1.2-1.6 times that barretter starts time length, the inverse that described setpoint frequency is setting value.
Further, described setting value is 400ms.
The present invention adopts car body controller to carry out break-make control to barretter loop and Electromagnetic Valve Circuit and realizes and overtaking other vehicles, in the time that passing light is not opened, the loop conducting of car body controller control barretter, go forward side by side after line delay and just disconnect barretter loop, realize and overtaking other vehicles by the flicker of country beam, guaranteed the charging duration of barretter; In the time that passing light is opened, car body controller control barretter loop maintains conducting state, and controls Electromagnetic Valve Circuit conducting, and driven by motor baffle rotates, and switches to realize overtake other vehicles by nearly distance light, has avoided discharging and recharging of barretter; Thereby extend the service life of barretter.
