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 bearing mechanism for a transverse leaf spring can be fitted in the area of a vehicle axle and has a holding device for holding the transverse leaf spring and a connecting device via for connecting the holding device to the vehicle. The holding and connecting devices and the transverse spring are designed such that when the transverse spring is in its installed position a cross-sectional plane of the transverse spring, that extends in the vertical and longitudinal directions of the vehicle, can pivot in the area of the mounting fixture during jouncing and rebound of the transverse spring, about a rotational axis that extends in the longitudinal direction. The holding and connecting devices, in the area of the mounting fixture, are designed such that the rotational axis of the cross-sectional plane of the transverse spring is vertically spaced from the neutral fiber of the transverse spring.

An axle for a motor vehicle comprises at least a transverse leaf spring () attached directly, or via an auxiliary support frame, to a body () of the motor vehicle by two first mountings (), two control arms () and two wheel carriers (). In each case, an end of the transverse leaf spring () facing toward a respective wheel () of the motor vehicle is rigidly connected to one of the two control arms (), and both of the two control arms () are each orientated substantially in the longitudinal direction of the motor vehicle. Each of the control arms () is connected by a second mounting () directly, or via an auxiliary support frame, to the body () and also connected, by at least one third mounting (), to one of the wheel carriers ().

Axle for a motor vehicle

A semi-trailing arm axle for a motor vehicle which comprises a semi-trailing arm () for each wheel () of the axle. Each semi-trailing arm () is flexible about the vertical axis and is mounted to the body or on a support frame by at least one mounting (). Each wheel () of the axle is connected to its respective flexible semi-trailing arm () by way of at least one wheel bearing (), and the flexible semi-trailing arm () is the sole wheel-guiding element.

The bearing mechanism comprises an outer bearing shell and insertion devices which have at least some regions encompassed by the outer bearing shell, and which each comprise layered elements having different stiffness. When assembled, the insertion devices are disposed between the outer bearing shell and the leaf spring. The leaf spring has a recess into which sections of the insertion devices engage. The recesses are located on opposed top and bottom surfaces of the leaf spring, with respect to a vertical axis of the vehicle. In the mounted state of the leaf spring, the recesses are delimited by top and bottom edge regions that are formed between top, bottom and lateral surfaces, in the longitudinal direction of the vehicle.
