Abstract
The invention relates to a method for adjusting a friction coefficient of an automated clutch, wherein a current friction coefficient (RK) is determined by a comparison with a moment of the internal combustion engine during a slipping phase of the clutch. In a method, in which the adaptation over the entire operation of the motor vehicle is possible, the current friction coefficient (RK) is pilot-controlled to a long-term friction coefficient (RL) in a non-slipping phase of the clutch and/or in the event of a torque signal that cannot be monitored.

A method for adapting a friction value of an automated clutch, the method comprising:
- (i) determining a current friction value (RK) by comparison with a torque of an internal combustion engine during a slipping phase of the clutch, and
- (ii) pilot controlling the current friction value (RK) to a long-term friction value (RL) during at least one of the following phases:
- (1) a non-slipping phase of the clutch, or
- (2) a non-monitoring phase of a torque signal.
A method for adapting a friction value of an automated clutch, the method comprising:
- (i) pre-setting a long-term friction value that is constant;
- (ii) determining a current friction value based on a comparative torque value during a slippage phase of the clutch, and
- (iii) adapting the current friction value to the long-term friction value during a constant driving operation and at least one of the following phases:
- (1) a non-slipping phase of the clutch, or
- (2) a non-monitoring phase of a torque signal.
