The invention relates to a method for checking a parameter correlating with a pressure in a pressure-dependent fluid-conveying system (10). The fluid-conveying system (10) comprises a current-controlled electric motor, which is controlled by the motor control device, and a fluid pump that is driven by the electric motor. The method comprises the step of determining of a rotary speed of the electric motor. Usually, an electric motor current is determined in a further step. A pressure value is calculated as a function of the rotary speed and the current. The calculated value is compared with the parameter. The invention further relates to a control device and a fluid-conveying system (10). |
