Abstract

A method for determining state values of a wheel (R) of a wheel drive module that includes the wheel (R), a speed modulation gearbox (G), a first electric motor (M1) and a second electric motor (M2), as well as at least one first sensor (S1) for sensing state values of the first electric motor (M1), at least one second sensor (S2) for sensing state values of the second electric motor (M2), wherein additional state value sources of the electric motors (M1, M2) and/or the wheel (R) are provided and the sensed state values are compared with each other in order to compensate for and to recognize errors in the sensing of the state values so that actual state values of the wheel (R) are determined from the individual sensed state values.
