Method for checking correct filling of e.g. hydraulic clutch operating system with pressurizing medium in motor vehicle, involves ensuring correct filling of system when pressure gradient is larger than given pressure gradient level

The method involves providing a sensor (5) for detecting pressure in a cylinder (4), and providing another sensor (6) for detecting position of an actuator (3) along an actuator path. Maximum pressure gradient of a position-pressure-curve in a predetermined range of a curve is determined, and correc...

Beschreibung
Zusammenfassung:	The method involves providing a sensor (5) for detecting pressure in a cylinder (4), and providing another sensor (6) for detecting position of an actuator (3) along an actuator path. Maximum pressure gradient of a position-pressure-curve in a predetermined range of a curve is determined, and correct filling of a hydraulic clutch operating system (1) with pressurizing medium (7) is ensured when the determined pressure gradient is larger than a given pressure gradient threshold level. The operating system is ventilated by a control device (2) during incorrect filling of the operating system. An independent claim is also included for a hydraulic operating system.
