Abstract
A motor vehicle monitoring apparatus has a controller as a component of a control loop for controlling the electric current of an actuator. The vehicle power supply system voltage of a motor vehicle voltage source is applied to the actuator. A correction unit is provided in the forward path of the control loop between the controller and a subordinate actuator element of the control loop and applies the actuation signal output by the controller with a correction factor which is proportional to the reciprocal value of the instantaneous vehicle power supply system voltage.
