Abstract
A piston-cylinder unit (40) for hydraulic actuation of a clutch in a vehicle, including a piston (42), a cylinder (41) and a sealing element (43). The piston cylinder unit is fluidically linked to a fluid circuit (44), the piston (42) is axially displaceable in the cylinder, and the sealing element is arranged sealingly between the piston and the cylinder, characterized in that a sensor is arranged in or on the piston-cylinder unit, by which sensor a pressure can be measured in the interior of the piston-cylinder unit and/or in the fluidically linked fluid circuit. A method for operating the piston-cylinder unit is also provided.
