Abstract

In a motor vehicle comprising a main electronic control unit (E), an airbag electronic control unit (E1), and a braking-system electronic control unit (E2), the direction of emission of a headlight unit is controlled by said main control unit (E) on the basis of a calculation of the value of the pitch angle (PitchAngle) of the motor vehicle, defined as inclination of the longitudinal axis (X) of the motor vehicle with respect to the road (6). This calculation is made exclusively on the basis of the values of the longitudinal acceleration (Long) of the motor vehicle, of the speed (V) of the motor vehicle, and of the angle of slope (Slope) of the road. The information on the value of the longitudinal acceleration (Long) of the motor vehicle is supplied by the airbag control unit (E1), whereas the information on the values of the speed of the motor vehicle (V) and of the angle of slope (Slope) of the road is supplied by the control unit of the motor-vehicle braking system (E2).
