The invention relates to a device for automatically adjusting the headlight range of a motor vehicle, comprising at least vertically adjustment headlights comprising a control unit provided with a sensor device which is used to detect vehicle and/or ambient data and an evaluation and control device which is used to determine control data for controlling the at least vertically adjustable headlights. The sensor device is embodied as a non-predictable working sensor which is used to detect the vertical roadway curving.

Device and method for adjusting the headlight range of a motor vehicle

A system for automatic headlight leveling control in a motor vehicle has two level sensors which are offset in the longitudinal direction for measuring the vehicle body pitch angle in the form of a level difference. An electronic control unit determines a desired value for the headlight adjustment as a function of the first derivative of the directly measured or further processed level difference. In one embodiment of the invention, electronic control unit determines a static level difference and a dynamic level difference, and the desired value is determined as a function of the first derivative or the second derivative of the dynamic level difference.

Automatic headlight leveling system for motor vehicles

In a method for regulating the headlight range of a vehicle as a function of the load, the vehicle speed is also taken into account to increase or decrease the headlight range at high or low speed. With the vehicle at rest, the headlight range can be further reduced by contrast with a vehicle operating at a lower speed. The same applies to driving on a highway with a rough surface.

Method for regulating the range of the headlights of a vehicle according

A switching device for the lighting system of motor vehicles includes a rotary switch which can be adjusted in different rotating positions, and devices for wiring the connected electric light devices corresponding to the settings of the rotary switch. The rotary switch furnishes control signals in its rotating position which can be differentiated from one another. The control signals are guided to a decision logic. The lighting devices can be switched by load switches which can be controlled by the decision logic.
