The control system comprises a combination switch, a ballast, a relay, a vehicle body controller, an electromagnetic valve and a light barrier driven by a motor, wherein one end of the combination switch is grounded and the other end of the combination switch is connected with the input end of the vehicle body controller; a first output port OUT1 of the vehicle body controller is connected with one end of a relay coil J1; a second output port OUT2 of the vehicle body controller is connected with one end of an electromagnetic valve coil J2; the other end of the relay coil J1 and the other end of the electromagnetic valve coil J2 are connected with a +12V power supply; a ballast loop is formed by a relay switch K1, the ballast and the supply power; and an electromagnetic valve loop is formed by an electromagnetic valve switch K2 and the motor. In the control method, the overtaking is controlled by adopting the vehicle body controller; if a vehicle is overtaken when a low beam lamp is not turned on, the charging time of the ballast can be ensured; and if the vehicle is overtaken when the low beam lamp is turned on, the charge-discharge of the ballast can be avoided, so that the service life of the ballast is prolonged.
Description
Technical field
The present invention relates to technical field of automotive electronics, be specifically related to a kind of overtake other vehicles control system and control method of the xenon front lamp based on far and near light one.
Background technology
Fast development along with the modern automobile technology; Increasing automobile selects for use xenon headlight as headlight; Because xenon headlight is in the advantage of aspects such as Illumination intensity; The use of xenon lamp has become a development tendency, and xenon headlight can be designed as the headlight of far and near light one, not only can save the arrangement space of headlight; And in the American-European statutory standard of up-to-date issue, also there are the regulation of forcing to arrange driving lamp, the xenon front lamp of so far and near light one must become the main flow design of the coming years.Yet lighting of xenon front lamp needs tens kilovolts high pressure, needs to introduce barretter.The groundwork of barretter is exactly to obtain high trigger voltage through discharging and recharging, and starts successfully back steady current.
For the xenon front lamp of far and near light one, when night travel was overtaken other vehicles, head light need carry out stroboscopic; The existing mode of overtaking other vehicles (as shown in Figure 3) is by combined switch SW direct control relay L1, thus direct control barretter H1 break-make, to reach the purpose of head light flicker; Yet the starting current curve according to barretter (is a kind of damped oscillation mode, in the time of 250ms, reaches current maxima, descend then; Be tending towards constant current), if do not control the make-and-break time of barretter, barretter will discharge under the situation of underfill electricity; Cause barretter internal circuit electric capacity to discharge and recharge unusually, greatly shorten the service life of barretter.
Summary of the invention
Overtake other vehicles control system and the control method that the purpose of this invention is to provide a kind of xenon front lamp based on far and near light one with the make-and-break time of control barretter, avoid shorten the service life of barretter.
The control system of overtaking other vehicles of the xenon front lamp based on far and near light one of the present invention; Comprise combined switch, barretter and relay, also comprise the baffle of car body controller, electromagnetic valve and driven by motor, an end ground connection of combined switch; The other end is connected with the input end of car body controller; The first delivery port OUT1 of car body controller is connected with the end of relay coil J1, and the second delivery port OUT2 is connected with the end of electromagnetic valve coil J2, another termination+12V power supply of the other end of relay coil J1 and electromagnetic valve coil J2; Relay switch K1 and barretter, power supply are formed the barretter loop, and electromagnetic valve switch K2 and motor are formed the electromagnetic valve loop.
Adopt the overtake other vehicles method of control of the control system of overtaking other vehicles of described xenon front lamp based on far and near light one to be: car body controller obtains dimmer control SW1 and the state of distance light switch SW 2 in the combined switch, analyzes and do following processing:
A: SW1 is not closed when dimmer control, and passing light is not opened, when car body controller receives the operation signal of distance light switch SW 2; Car body controller control relay K switch 1 is connected the barretter loop; Country beam is lighted, and breaks off the barretter loop after the car body controller delay adjustments value, and country beam extinguishes; Flicker through country beam realizes overtaking other vehicles, and the frequency of country beam flicker is smaller or equal to the operating frequency of distance light switch SW 2;
B: as dimmer control SW1 closure, passing light is opened, and the barretter loop has been in conducting state; When car body controller received the operation signal of distance light switch SW 2, conducting state was kept in car body controller control barretter loop, and control electromagnetic valve K switch 2 is connected the electromagnetic valve loop; The driven by motor baffle rotates; Baffle is reflected into distance light with dipped beam, switches through nearly distance light and realizes overtaking other vehicles, and the frequency that nearly distance light switches is identical with the operating frequency of distance light switch SW 2.
Further, SW1 is not closed at dimmer control, 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 said setting value, the frequency of car body controller control country beam flicker is identical with setpoint frequency;
If continuous handling interval greater than equaling said 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, said setting value is 1.2-1.6 a times that barretter starts time length, and said setpoint frequency is the inverse of setting value.
Further, said setting value is 400ms.
The present invention adopts car body controller that break-make is carried out in barretter loop and electromagnetic valve loop and controls and realize overtaking other vehicles; When passing light is not opened; The loop conducting of car body controller control barretter; Go forward side by side and just break off the barretter loop behind the line delay, the flicker through country beam realizes overtaking other vehicles, and has guaranteed the charging duration of barretter; When passing light was opened, conducting state was kept in car body controller control barretter loop, and the conducting of control electromagnetic valve loop, and the driven by motor baffle rotates, and switches through nearly distance light and realizes overtaking other vehicles, and has avoided discharging and recharging of barretter; Thereby prolonged the service life of barretter.
