Classification: CPC B  G | IPC B  G

Claim 6:
7. The method according to claim 1, wherein the motor vehicle is equipped with an automatic dynamic lighting range regulating device, which includes at least one electronic control unit that is intended to determine an instantaneous pitch angle of the motor vehicle in response to received data of sensors and to control the vehicle headlamp system in such a way that a predetermined lighting direction angle with respect to a roadway plane is adjusted, and wherein the method further comprises the steps of:
when the roadway anomaly is detected, transmitting results of the step of detecting the roadway anomaly in relation to ranges and at least one quantity from among a vertical dimension (hi) of the roadway, a gradient (gradx;i) of the roadway in the forward driving direction, and an instantaneous speed (vmom) of the motor vehicle to an electronic control unit;
in response to a previous calibration and the transmitted results, calculating an expected time variation of the pitch angle of a body of the motor vehicle when driving over the roadway anomaly; and
controlling, as a function of driving over the roadway anomaly by the motor vehicle, the lighting range regulating device in order to compensate for a deviation of a lighting direction angle from a predetermined lighting direction angle with respect to a roadway plane during a pitch movement of the body of the motor vehicle according to signals from sensors including a pitch angle determination sensor.
