Abstract
A method for clutch control for wet clutches includes the following steps: determining whether a viscosity of clutch fluid lies above a predetermine threshold value; when the determined viscosity is above the predetermined threshold value: adaptation of the clutch/gear control with respect to clutch/gear control for routine operation in such a manner that additional clutch energy will be transmitted to the clutch fluid and that the clutch fluid is heated by the additional energy; and checking to see whether the viscosity of the clutch fluid during the altered clutch control operation is above the threshold value and, if that threshold value is not reached, return to clutch/gear control for routine operation.
Claims9
A method for clutch control of wet clutches, comprising the following steps:
- (a) determining whether a viscosity of clutch fluid lies above a predetermined threshold value;
- (b) when the viscosity determined under step (a) is above the predetermined threshold value, adapting clutch/gear control with respect to clutch/gear control for routine operation in such a fashion that additional clutch energy is transmitted to the clutch fluid and that the clutch fluid is heated by the additional energy;
- and,
- (c) (after step (b)):
- checking to see whether the viscosity of the clutch fluid is still above the threshold value and, if the threshold value is not reached, return to clutch/gear control for routine operation.
