Abstract
A method and device for operating a clutch between an internal combustion engine and at least one driven wheel of a vehicle, a torque being transmitted between the internal combustion engine and the driven wheel by pressing the clutch together via an application force or an application pressure, and the application force or the application pressure being controlled as a function of a clutch slip in the clutch when the torque is transmitted between the internal combustion engine and the driven wheel and a setpoint clutch slip.
Claims7
A method for operating a clutch between an internal combustion engine and at least one driven wheel of a vehicle, comprising:
- transmitting a torque between the internal combustion engine and the at least one driven wheel by pressing the clutch together in accordance with one of an application force and an application pressure;
- and
- given a setpoint clutch slip, and when the torque is transmitted between the internal combustion engine and the at least one driven wheel, regulating the one of the application force and the application pressure as a function of a clutch slip in the clutch;
- and
- regulating the one of the application force and the application pressure by an inverse clutch model that calculates the one of the application force and the application pressure as a function of the torque transmitted by the clutch.
A device for operating a clutch between an internal combustion engine and at least one driven wheel of a vehicle, comprising:
- an arrangement for transmitting a torque between the internal combustion engine and the at least one driven wheel by pressing the clutch together in accordance with one of an application force and an application pressure;
- a slip controller for regulating the one of the application force and the application pressure as a function of a clutch slip in the clutch, when the torque is transmitted between the internal combustion engine and the at least one driven wheel, and given a setpoint clutch slip, wherein:
- the slip controller includes an inverse clutch model to calculate the one of the application force and the application pressure as a function of the torque transmitted by the clutch.
