Abstract: A method operates a motor vehicle having a hybrid drive with a first drive machine and a second drive machine, the first drive machine being an internal combustion engine and the second drive machine being an electric machine, operation of at least one of the drive machines requiring an adaptation in which the internal combustion engine is started. The method includes the use of a navigation device to identify at least one of a present position, a direction of travel or a travel route. An adaptation with a start of the internal combustion engine is postponed or eliminated based on at least one of present position data, present direction of travel data, present route data, predicted position data, predicted direction of travel data or predicted route data.

Abstract: A method for carrying out a boosting mode of a drive unit (3), having at least one internal combustion engine (1) and at least one electric machine (2), of a vehicle (10), in which, in order to prepare the boosting mode, the internal combustion engine (1) is adjusted to an operating state with an increased acceleration potential, and in order to charge an energy accumulator (4) the electric machine (2) is adjusted to a generator mode. When a power demand which is increased compared to the current operating state of the drive unit (3) is present, the charging process is interrupted and at the same time the electric machine (2) is activated in order to increase the driving power of the drive unit (3), wherein the increased acceleration potential which is kept in reserve by the internal combustion engine (1) is utilized.

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.
