Abstract:
1. Method for controlling a clutch unit for a drive train of a motor vehicle, the clutch unit including a wet friction clutch for controllable transmission of a torque from an input element to an output element of the clutch unit; oil for cooling the friction clutch; and an actuator for actuating the friction clutch; the method comprising the following steps: ascertaining a temperature of the oil and wherein the oil temperature ascertained is offset with a heat input that corresponds to the power dissipation produced in the friction clutch; adapting, as a function of the ascertained temperature, a characteristic curve of the friction clutch that describes the dependence of a clutch torque on an actuator control variable; and controlling the clutch unit in accordance with the characteristic curve by means of the actuator.
