Abstract: A display device for a motor vehicle having an internal combustion engine for at least temporarily driving the motor vehicle, and for displaying operating-time-related data of the internal combustion engine. The display device is characterized in that the operating-time-related data are provided as portions of the operation of the motor vehicle with a switched-off internal combustion engine at entities (E, E?, E?, . . . ) occurring earlier on the route of the motor vehicle. The display device is configured to display these data in the manner of a histogram.

Abstract: The invention relates to a method for operating a drive train (1) comprising an internal combustion engine (2), an electric motor (10) and an automatic transmission (11), in which, during an operating state with the electric motor (10) switched on and the internal combustion engine (2) switched off, the internal combustion engine (2) is engaged by a transmission of torque to the internal combustion engine (2), used to accelerate the internal combustion engine (2), being coupled in time with a downshift operation in the automatic transmission (11).

Abstract: A method and a device for controlling a hybrid vehicle drive. The device contains a multiplicity of control parameter sets with different set point charge states for a high performance battery of the electric motor. The set point charge states are assigned to a respective operating mode of the vehicle. A definition device for defining a current operating mode of the vehicle, as a result of which a control parameter set which corresponds to the defined current operating mode of the vehicle can be used to control a charge mode of the high performance battery of the electric motor with a corresponding set point charge state.

Abstract: A drivetrain of a motor vehicle has an internal combustion engine, an electric motor, a transmission, and a torque converter with a converter bypass clutch. The drivetrain is controlled such that, during an electric operating mode in which the internal combustion engine is deactivated and the electric motor is activated, and/or during a recuperation operating mode in which the internal combustion engine is deactivated and the electric motor is operated as a generator, the converter bypass clutch is permanently closed, at least between shift processes of the transmission, in order to bypass the torque converter.

Abstract: A method and a device control a hybrid vehicle drive. The device contains a multiplicity of control parameter sets having different recovery torques for a conversion control device which sets a recovery torque of the electric motor in an overrun phase, which recovery torques are assigned a respective driving mode indicator. A definition device is provided for defining a current driving mode indicator, as a result of which a control parameter set corresponding to the defined current driving mode indicator can be used to control the conversion control device in an overrun phase of the hybrid vehicle drive.
