Abstract
Driving assistance device for a motor vehicle, including at least one emitter of radiation toward the front of the vehicle, a receiver of part of this radiation reflected by a target vehicle, and control and calculation means for influencing the acceleration and braking of the following vehicle in accordance with information coming from the unit comprising the emitter and the receiver and in accordance with data pertaining to the following vehicle. At least the emitter is mounted so as to be rotatable in terms of the azimuth and means for driving the emitter in rotation are provided in order to modify the azimuth of the beam of the emitter in accordance with the curvature of the road. This beam advantageously turns by the same angle as that of the beam of an adaptive lighting system.
