Device for triggering a lighting device in a motor vehicle

摘要

A device for triggering a lighting device of a motor vehicle has a control arrangement (10) which generates at least one pulse width modulated control signal (16) for at least one switching means (18) via which at least one lighting device (20) may be supplied with electric power. The control arrangement (10) receives a measure of the power supply voltage (UB) supplied at least to the lighting device (20) in order to influence the control signal (16) as a function of the power supply voltage (UB). The control arrangement (10) determines the control signal (16) as a function of at least one additional operating parameter (v)-in addition to the power supply voltage (UB)-of the motor vehicle.
