A drive device has an internal combustion engine connection configured for receiving driving power from an internal combustion engine and has an electric motor generator configured for outputting driving power to an electric motor generator connection. A coupling device is configured for coupling both the internal combustion engine connection and the electric motor generator connection to at least one power train connection that is configured for outputting driving power to a power train. The coupling device has a radially outer drive part and a coupling portion lying radially within the drive part, which coupling portion is configured for selectively connecting the drive part to the power train connection in a rotationally fixed manner. A power transmission portion is arranged on an outer circumferential surface on the radially outer drive part, which power transmission portion is configured for receiving driving power from the electric motor generator. Both the internal combustion engine connection and the electric motor generator connection are arranged concentrically to a main drive axis. The power transmission portion partially or fully covers the coupling portion in the longitudinal direction of the main drive axis. An electric motor axis, about which an electric motor shaft configured for outputting driving power from the electric motor generator is provided, which electric motor axis is arranged axially parallel to and radially spaced from the main drive axis.

Drive device of a hybrid drive

A method for operating a transmission of a vehicle, where the transmission couples a drive machine of the vehicle to a driven wheel of the vehicle and has different rotational speed transmission ratios. The method determines that a special load situation prevails or will prevail at the driven wheel of the vehicle. The method determines a shift time or a shift vehicle position, at which a load on the drive machine is less than or equal to a load threshold value. The method adapts the rotational speed transmission ratio of the transmission for the special load situation at the shift time or at the shift vehicle position.
