Abstract

An apparatus for controlling a fluid pump for a motor vehicle includes: a first controller configured to actuate an electric prime mover of the fluid pump by impressing at least one motor current with an adapted current intensity and an adapted waveform; and a second controller configured to detect a rotational speed of the electric prime mover and to apply an adapted voltage to the electric prime mover on the basis of the detected rotational speed.
