  • Method for operating at least one electric machine
    Patent number: 10778133
    Abstract: A method for operating at least one electric machine that is designed to drive a vehicle, in which a value is determined for at least one operating parameter of the vehicle, wherein a change is predicted for the torque of the at least one electric machine at a target time point from the value of the at least one operating parameter, wherein a current for a magnetization of the at least one electric machine prior to the target time point is set at a value, wherein the value of the current for the magnetization at the target time point is changed and adapted.

  • Method for operating an electric or hybrid vehicle with shiftable transmission and electric or hybrid vehicle
    Patent number: 10059329
    Abstract: At least one electric motor is employed for propelling an electric or hybrid vehicle with a shiftable transmission. Upon reaching a shift threshold, a shift operation is performed in the transmission of the vehicle, wherein a value specifying the shift threshold is varied depending on at least one parameter. As the at least one parameter, a speed is used, at which a power provided by the at least one electric motor for propelling the vehicle has a maximum.
