Patent ID: 8589016

Claim:
A motor vehicle control device for a motor vehicle having a motor vehicle voltage source connected in a vehicle electrical system and an actuator, the control device comprising: a controller forming a component of a control loop for controlling an electric current of the actuator, wherein a voltage of the vehicle electrical system voltage is applied to the actuator; a correction unit connected in a forward path of the control loop between said controller and a downstream actuating element of the control loop, said correction unit causing a correction factor proportional to a reciprocal of an instantaneous vehicle electrical system voltage to be applied to an actuating signal output by said controller; a voltage measuring device for measuring the vehicle electrical system voltage between the vehicle voltage source and the correction unit, said voltage measuring device having an input; and a lowpass filter preceding said input of said voltage measuring device, said lowpass filter configured to filter out disturbance frequencies of the vehicle electrical system voltage above a PWM frequency of a PWM generator disposed downstream of said correction unit in the controller circuit and used for controlling the actuating element by way of pulse width modulation signals.
