    Abstract: A method of modeling initial temperatures of a dry DCT includes reactivating a controller after a time lapse between first and second clock times representing an offline period. The last known temperatures of a first component and a second component are read and a first temperature difference therebetween is calculated. The method calculates a stop time and a start time on a predefined exponential function from the calculated temperature difference. A first conductive heat transfer between the first and second components is calculated by integrating the predefined exponential function between the stop time and the start time. Based upon the calculated first conductive heat transfer, a first conductive temperature change between the first and second components is calculated. A starting temperature of the first component is calculated from first conductive temperature change, and a control action on the dry DCT is executed based upon the calculated starting temperature.

    Abstract: A method for approximately determining the torque actually transmitted by a clutch of a drive train of a vehicle, includes the steps of: setting a closed state of the clutch and transmitting a torque by way of the drive train, providing a state space model showing the drive train, particularly a Kalman filter, determining a torque which can theoretically be transmitted or is transmitted by the clutch in the closed state, and approximately determining the torque actually transmitted by the clutch, by adding the theoretically transmittable or transmitted torque and a disturbance torque determined by calculation, wherein the disturbance torque is determined on the basis of the state space model and actual rotational speeds of individual drive train components and/or of actual torques transmitted by individual drive train components.
