Headlight optical axis control device , headlight optical axis control system and test methods

摘要

When performing an operation test of the headlight optical axis control system comprising a headlight optical axis control device 1 and the optical axis adjusting mechanism 11, the tester swings the vehicle body 10 in a specific rocking pattern . An equivalent specific artificial oscillating pattern, using a substantially continuous tilt angle of the vehicle body 10 detected by the inclination angle sensor 2 of the radio wave type, swing pattern detection unit 3 detects, optical axis control section 4 since switching the control from slow travel optical axis control of the response to the agile test optical axis control of the response, it is possible to perform the operation test easily.
