Abstract:
The disclosure relates to a method for controlling a first electric motor (M1) and a second electric motor (M2) of a wheel drive module, wherein the wheel drive module comprises a wheel (R) and a speed modulation gearbox (G), and wherein the wheel (R) is drivable about a wheel axis (A) jointly by the first and the second electric motors (M1, M2) by means of the speed modulation gearbox (G) and steerable about a steering axis (L) which is orthogonal to the wheel axis (A), wherein electrical control signals for controlling the first and second electric motors (M1, M2) are determined from wheel reference values which characterize the driving and/or the steering of the wheel (R).
