Abstract:
A method is provided for operating a motor vehicle drive train having an internal combustion engine, an electric motor and an electrical energy storage. An actual charge state of the electrical energy storage is detected and compared with an established setpoint charge state to determine one of several operating modes for the drive train. The setpoint charge state is determined as a function of an instantaneous driving state of the motor vehicle so that conclusions can be drawn about imminent deceleration, imminent acceleration or imminent cruise control, instantaneous transmission data and/or instantaneous hybrid drive data. Range boundaries and/or range extents of operating modes are shifted as a function of the setpoint charge state.
