Abstract

A device for the dynamic adjustment of the position of headlamps (8) of a vehicle as a function of the relative position of the wheels to the vehicle body is shown and described. The device has two sensors (1, 2) for the delivery of signals corresponding to the relative position and has actuating members (7) connected to the headlamps (8). The actuating members (7) can be controlled by a control device (6) and the control device (6) is supplied with the position signal, it being possible to eliminate undesired frequencies of the position signal by means of a low-pass filter (4). In order to make possible pleasant night driving in vehicles under all driving conditions and irrespective of the state of the road, the filter (4) has filter elements (11 to 14) via which a variable characteristic of the frequency separation is ensured as a function of the amplitude of the position signals of the sensors (1, 2). <IMAGE>
