Abstract
A device for detecting an operating pressure of a fluid pump for a motor vehicle includes: a rotational speed detector configured to detect a rotational speed of the fluid pump; a pump current detector configured to detect at least one current of the fluid pump; a memory configured to store a pump current/rotational speed performance map with at least one pressure reference point; and a pressure determining device configured to determine a fluid pressure that prevails in the fluid pump based on the detected rotational speed, the detected current and the stored pump current/rotational speed performance map.
