Claims8
An automobile headlamp system, comprising:
- a headlamp rotatable about a yaw axis;
- and
- a controller adapted to control a rotary movement of the headlamp, wherein the controller ascertains that the automobile is in an unstable driving situation during which a deviation occurs between steering lock and actual direction of travel of the automobile, and, in response to ascertaining that the automobile is in the unstable driving situation, the controller controls the rotary movement of the headlamp to reset the headlamp to a zero angle position during the unstable driving situation, wherein the zero angle position is straight ahead in a longitudinal direction of the automobile.
Dependencies are inferred from the claim text.
