A method of determining clutch parameters at the initial start of operation of a friction clutch in a motor vehicle comprising the steps of: in a first phase, moving the clutch from an open state into a closed state and into an open state again at a predetermined constant slip of the clutch and determining and storing the position of the clutch during the movement when predetermined clutch torque thresholds are reached; in a second phase, in a first step, determining a touch point, a position hysteresis, and a torque hysteresis from the determined positions; determining a preliminary friction coefficient; determining preliminary form factors; determining a final friction coefficient; and determining final form factors. |

1. A method of determining clutch parameters at an initial start of operation of a friction clutch in a motor vehicle comprising the steps of:
in a first phase:
moving, using a control unit, the clutch from an open state into a closed state and into the open state again at a predetermined constant slip of the clutch; anddetermining and storing, using the control unit, a position of the clutch during the movement when predetermined clutch torque thresholds are reached; in a second phase, in a first step, determining, using the control unit, a touch point, a position hysteresis, and a torque hysteresis from the determined position; determining, using the control unit, a preliminary friction coefficient; determining, using the control unit, preliminary form factors; determining, using the control unit, a final friction coefficient; and, determining, using the control unit, final form factors. |
