  • Publication number: 20210188328
    Abstract: A drive system for a vehicle includes a plurality of electric traction motors, each mechanically coupled to at least one drive wheel to generate traction. At least one traction power converter is connected on an AC voltage side to at least one electric traction motor to supply the electric traction motor with electric power. A traction control unit for controlling at least one traction power converter is provided and is designed to control the at least one traction power converter while the vehicle is moving based on electrical output alternating quantities of the at least one traction power converter. A rotational movement of the at least one drive wheel of the vehicle during standstill of the vehicle is not detected by a separate detection unit based on the output alternating quantities.
