A universal modeling method is provided for a motor vehicle, the universal modeling method including: providing an input signal set, the input signal set comprising those signals of respective sensors of the motor vehicle which can be relevant for the control of devices of the motor vehicle; selecting a set of modeling signals from the input signal set as a function of a system architecture of the motor vehicle; and determining an output signal set by way of a time-discrete selective state space model modeling function taking into account the set of modeling signals. In this case, the output signal set functions as a signal set for controlling corresponding actuators of the devices of the motor vehicle.

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.

A method and controller are provided for controlling a power train of a vehicle having a number of modes of operation. A first controller is provided for controlling of a first function of the vehicle. At least one second controller is provided for controlling of a second function of the vehicle. The first controller and the at least one second controller are combined in a joint controller having a state observer and a number of controlling entities. The joint controller is operated by a set of formal controlling parameters assigned to the controlling entities. Actual parameters of the set of formal controlling parameters are switched according to a current mode of the number of modes of operation.
