  • Method for operating a transmission device for a motor vehicle, and corresponding transmission device
    Patent number: 10288167
    Abstract: A method for operating a transmission device for a motor vehicle. A drive gear is selected from a drive gear set and set on a transmission and upon going above a rotational speed upper limit a drive gear with a larger gearing ratio and upon going below a rotational speed lower limit a drive gear with a smaller gearing ratio is selected from the drive gear set and set on the transmission. In a normal operating mode, the drive gear set corresponds to a normal operation drive gear set having a plurality of different drive gears, and the rotational speed upper limit corresponds to a normal operation rotational speed upper limit and the rotational speed lower limit corresponds to a normal operation rotational speed lower limit. In an alternative operating mode the drive gear set corresponds to an alternative operation drive gear set, having a smaller number of different drive gears than the normal operation drive gear set.

  • 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.
