Description
Technical field
The invention belongs to automotive field, relate to a kind of according to car body obliqueness signal and turn signal automatically about, the intelligent illuminating system of automobile headlight of left and right adjusting headlamp.
Background technology
Along with the continuous progress of automotive engineering, automotive safety more and more receives publicity.At present the headlamp of automobile all is fixing fore both sides, the light of headlight can not about, about regulate automatically, have potential safety hazard.When vehicle under steam acceleration, deceleration and parking handling goods, up and down during passenger etc., the capital is caused the variation of the forward and backward axle of vehicle load and is changed the body gesture of vehicle, and the irradiation of headlight height can not change adjusting automatically according to this, the road surface radiation response of headlamp will be influenced, even can send a car to cause to the opposite and dazzle the eyes, influence traffic safety.When automobile was kept straight on night, light can also be radiated on the road surface of direction of advance, and good sight line can be arranged, but when walking to detour, light but departs from direction of advance, causes the driver not see the road surface situation, also can influence traffic safety.
Summary of the invention
The invention discloses a kind of intelligent illuminating system of automobile headlight, comprising self-checking device can regulate the illuminator level of headlamp automatically according to the variation of car body load-carrying, avoid causing and dazzle the eyes to the opposite vehicle; Simultaneously can also be according to wheel steering angle and GES, turn to when travelling at vehicle body, automatically adjust the left rotation and right rotation angle of dipped headlights, the light of headlamp is impinged upon on the road surface of driver's needs, for the driver provides good road lighting effect, produce the shortcoming at illumination dead angle when having remedied turning driving, make the driver grasp the place ahead road conditions in advance, improved the active safety of driving.
Specifically describe the technical scheme of intelligent illuminating system of automobile headlight below.
A kind of headlamp intelligent illuminating system comprises headlamp and automaton, and wherein headlamp comprises light source, speculum and lamp body; Automaton comprises vehicle speed sensor, overall height sensor, rotation direction sensor, control module ECU, stepper motor and the axle that fascinates; Stepper motor connects the axle that fascinates, and the axle that fascinates is connected on the speculum, about the action of stepper motor makes the optical axis of speculum change to do by the axle that fascinates, left and right adjusting.
The overall height sensor is arranged on the fore suspension and rear suspension of vehicle, the signal of collection vehicle load change, the signal of gathering is passed to control module ECU, ECU carries out data to be handled, when the changing value of judging signal during greater than setting value, send control command, drive headlamp by stepper motor and do upper and lower automatic adjusting.
Vehicle speed sensor is gathered GES, when vehicle speed sensor collects the speed of a motor vehicle greater than setting value, be arranged in the steering angle signal of the rotation direction sensor collection steering wheel on the steering column, steering angle signal and GES are passed to control module, control module carries out data to be handled, when the changing value of signal during greater than setting value, send control command, drive headlamp by stepper motor and do left and right automatic adjusting.
The present invention can in time regulate headlamp automatically according to the variation of vehicle attitude and steering angle, has reasonable in designly, be quick on the draw, and precise control, anti-interference, stable and reliable for performance, environmental suitability is strong, uses advantages such as easy to maintenance.
