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 or regulated as a function of the temperature of the clutch.
Claims14
A method for operating a clutch (3) between an internal combustion engine (1) and at least one driven wheel (8, 9) of a vehicle, a torque being transmitted between the internal combustion engine (1) and the driven wheel (8, 9) by pressing the clutch (3) together via an application force or an application pressure (p),
- wherein the application force or the application pressure (p) is controlled or regulated as a function of the temperature of the clutch (3), in particular using a temperature model (78).
The method according to one of the preceding claims,
- wherein the application force or the application pressure (p) is regulated as a function of the difference between the clutch slip and the setpoint clutch slip, in particular when the temperature of the clutch (3), the temperature of a friction surface of the clutch (3) or the temperature of the oil used to lubricate or cool the clutch (3) is less than or equal to the threshold value.
The method according to one of the preceding claims,
- wherein the application force or the application pressure (p) is regulated by an inverse clutch model which calculates the application force or the application pressure (p) as a function of the torque transmitted via the clutch (3).
A device for operating a clutch (3) between an internal combustion engine (1) and at least one driven wheel (8, 9) of a vehicle, in particular according to a method according to one of the preceding claims, a torque being transmitted between the internal combustion engine (1) and the driven wheel (8, 9) by pressing the clutch (3) together via an application force or an application pressure (p),
- wherein a pressure regulator (21) is provided to control or regulate the application force or the application pressure (p) as a function of the temperature of the clutch (3), the temperature of a friction surface of the clutch (3) or the temperature of the oil used to lubricate or cool the clutch (3).
