Headlamp beam angle adjustment device according to the Bishop vehicle detection

摘要

The subject innovation provides for the adjustment device according to the irradiation of the headlamp Bishop vehicle detection for adjusting downward the irradiation angle of the headlight by sensing the proximity state of another vehicle in the Bishop of dark ambient light condition.; Accordingly, the subject innovation is an ultrasonic transmission processing section (6,8) for transmitting side to the other vehicle that Bishop ultrasound signals having a bath book portion (2,4) to the light level around the vehicle detects a dark condition, the value of the predetermined pulses, Bishop ultrasonic receiving processing 10 and 12, wherein the ultrasonic bath illustrated book chapters from one of the ambient light sensing a dark state by the (2,4) state receives the ultrasonic signal reflected from the other vehicles to detect the distance difference hagoseo recognize the proximity state of the vehicle on the basis Bishop detection value of the distance difference of the other vehicle to Bishop on after the transmission of the ultrasonic signal transmission processing part (6, 8) are detected through the ultrasonic wave reception processing unit 10, 12 headlight ( by the operation of the control unit 14 performs control for downward adjustment of 22 and 24), the controller (irradiation which is driven under the control of 14) each adjusting driver 16 and the beam angle adjustment drive (16) survey of the headlight (22, 24) And the actuator includes a (18, 20) for performing an operation for adjusting the downlink is characterized in that configured.
