A transmission for a bicycle includes at least four shift elements, one input shaft (), a first planetary gear set (PS) which is operatively connected to the input shaft (), and a second planetary gear set (PS). A carrier of the first planetary gear set is rotationally fixed to a carrier of the second planetary gear set (PS).

A transmission (G) includes an input shaft (GW), an output shaft (GW), an electric machine (EM), a plurality of planetary gear sets (P-PP-P), and gear-implementing shift elements (S-SS-S). Via engagement of a first of the gear-implementing shift elements (SS), which is a force-locking shift element having a variable torque transmission capacity, the input shaft (GW) and an element (EE) of one of the planetary gear sets (PP) can be brought into a fixed rotational speed relationship with respect to each other. Another element (EEE) of one of the planetary gear sets (PPP) is permanently connected to a rotor (R) of the electric machine (EM). By engaging an auxiliary shift element (ZS,ZSa,ZSb), which is a form-locking shift element, the rotor (R) and the input shaft (GW) can be brought into a fixed rotational speed relationship with respect to each other.

Transmission for a motor vehicle, drive train and method for operating a transmission

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.
