Abstract:
A device for automatic correction of the orientation of at least one motor-vehicle headlamp upon attitude variations of the motor vehicle, including:an emitter projecting, onto the ground in front of the vehicle, two light spots which are spaced apart in a direction parallel to the longitudinal axis of the vehicle, a sensor of the illumination of the light spots comprising an objective forming images of the two light spots on a surface and supplying an output signal for each of the light spots, processing means suitable for deriving a control signal from the output signal from the sensor, and an actuator controlled by the control signal and able to alter an elevation orientation of a reflector of the headlamp, wherein the control signal for the actuator is derived by the processing means from a linear function of the output signals supplied by the sensor for each image of each light spot.
