Abstract
A method for actuating a clutch with a clutch actuation system, wherein an axially moveably mounted first piston (4) arranged on a master-side is moved via an electric motor, and the movement thereof is transmitted via a hydraulic section (8) to a second piston (10) positioned on a slave-side, which second piston actuates the clutch (11), wherein a path change triggered by the movement is measured and evaluated. In a method, in which a path change can be immediately measured, the path change of the clutch (11) detected on the slave-side is converted into an acoustic signal, which is transmitted via the hydraulic section (8) to the master-side for evaluation.
Claims17
A method for actuating a clutch with a clutch actuation system, the method comprising:
- moving an axially moveably mounted first piston arranged on a master side using an electric motor;
- transmitting a movement of the first piston via a hydraulic section to a second piston positioned on a slave side;
- actuating the clutch with the second piston;
- measuring and evaluating a change in travel caused by the movement by converting the change in travel of the clutch detected on the slave side into an acoustic signal;
- and
- transmitting the acoustic signal via the hydraulic section to the master side for evaluation.
A clutch actuation system, comprising:
- a clutch actuator including an electric motor, a transmission connected to the electric motor, a first piston connected to the transmission and axially moveably mounted in a master cylinder of the clutch actuator, wherein the clutch actuator is positioned on a master side;
- a hydraulic section;
- a slave cylinder on a slave side, the slave cylinder including a second piston, and the second piston is connected to the clutch actuator via the hydraulic section, the second piston is configured to be in an operative connection with a clutch via a release bearing;
- a travel measuring device that outputs acoustic output signals arranged on the slave side, the travel measuring device being configured to detect a change in travel of the clutch and being connected via the transmission section that transmits the acoustic signals to a receiving device;
- and
- an evaluation device connected to the receiving device.
