Device for the automatic adjustment of the position of the headlights on a motor vehicle
First Claim
1. A device for the automatic adjustment of a position of at least one headlight of a motor vehicle in relation to a bodywork by pivoting around at least one axis which is essentially parallel to a road surface, said device comprisingat least one actuator having a motor capable of pivoting said headlight;
- initialization means for adjusting the motor back to a nominal position;
adjustment means for monitoring progress of said initialization means, said adjustment means being accessible from outside the actuator and connected to a warning device;
at least one sensor integral with said motor vehicle; and
at least one electronic control system adapted to control the actuator with aid of information provided by the sensor, the electronic control system-being fixed to or implanted in the actuator.

Abstract
The aim of the invention is a device for the automatic adjustment of the position of at least one headlight of a motor vehicle in relation to the bodywork by pivoting around at least one axis which is essentially parallel to the road surface, the said device comprising at least one actuator capable of making the said headlight(s) pivot, at least one sensor integral with the vehicle, and more particularly fixed to the chassis close to one of the vehicle wheels, and at least one electronic system to control the actuator with the aid of information provided by the sensor(s). The said electronic control system, or at least the essential part of its components, is fixed to or implanted in the actuator.
