A tire () rolls on a surface (). A method () for providing maximum traction coefficient between the tire () and the surface () include steps for detecting a momentary slip of the tire () on the surface (); detecting a momentary traction coefficient; forming a tuple () from the slip and the current traction coefficient; choosing a characteristic curve () from a number of predetermined characteristic curves () on the basis of the tuple (), whereby each characteristic curve () describes a traction behavior of the tire () or a corresponding characteristic pitch; determining the maximum traction coefficient on the basis of the selected characteristic curves (); and thus providing the maximum traction coefficient.

Determining a maximum frictional-connection coefficient

A method for estimating a probability distribution of the maximum coefficient of friction (&#x3bc;) at a current and/or future waypoint (s, s*) of a vehicle. According to the method, a first probability distribution (WV) for the maximum coefficient of friction (&#x3bc;) at the waypoint (s) of the vehicle is determined by a Bayesian network from a first data set, which is, or was determined, for one, in particular current, waypoint (s) of the vehicle and which characterizes the maximum coefficient of friction (&#x3bc;) at the waypoint (s) of the vehicle.

A method for actuating a continuously variable clutch such that the torque to be transmitted by the clutch is continuously adjusted either electromechanically via an electromotive drive, hydraulically via a pressure actuator, or electromagnetically via an electromagnetic actuator. The torque transmitted by the clutch is adjusted by utilizing a position-dependent clutch torque specification.
