Abstract
An electrical control unit, or ECU, for a vehicle actuation system is described. The electrical control unit determines a current consumption of a current controlled actuator and comprises an input to receive an input signal from the current controlled actuator, an adder to add a bias signal to the input signal, an amplifier to generate an amplified signal by amplifying the signal output by the adder, a subtractor to subtract a signal representative of the bias signal from the amplified signal, and a determining unit to determine the current consumption from the signal output by the subtractor.
