Headlight swiveling device for vehicle, has control unit, which determines desired swiveling angle based on angular yaw rate, steering wheel angle, vehicle speed and actual light width

摘要

The swiveling device has a control unit (1) for receiving, as inputs, values of angular yaw rate r, steering wheel angle (LRW), vehicle speed (v) and actual light width (LW), and outputting a desired swiveling angle (SW). The swiveling angle then controls an adjusting device (2) for swiveling a headlight (3) accordingly. The desired swiveling angle (SW) in the region of a discrete limit vehicle speed (vgrenz) is derived from a rate of steering wheel angle to swiveling angle (SWLRW) and a rate of angular yaw rate to swiveling angle (SWr) using a mathematical equation: SW=SWLRW + SWr.
