Abstract
A method and a device for actuating a motor vehicle clutch device (4). A control device (12) automatically influence the frictional power of the clutch device (4) in accordance with predetermined criteria (19) by varying the continuously variable ratio of a vehicle transmission (2).
Claims7
A method for actuating a clutch device and controlling frictional power of the clutch device in a motor vehicle and affecting the frictional power and a temperature of the clutch device and the clutch device being housed within a power train containing a continuously variable ratio transmission, the method comprising the steps of:
- adjusting a continuously variable ratio of the transmission so that a maximum rotational speed difference between an input side and an output side of the clutch device is not exceeded;
- and
- controlling the continuously variable ratio of the transmission so that a rotational speed difference between the input side and the output side of the clutch device corresponds to one of a fixed nominal value, a variable nominal value or a nominal value range.
