A motor vehicle having a drive train and a motor unit which can be coupled to the drive train, and at least one electric machine. A freewheel mode is activated to increase the energy efficiency so that the motor vehicle is neither powered nor decelerated by the motor unit, thus allowing the wheels of the motor vehicle to essentially roll freely. In the freewheel mode, the electric machine is operated as a motor which introduces a freewheel mode pull torque to the drive train.

Method for controlling the operation of a motor vehicle

A method and an apparatus for controlling the hybrid drive of a motor vehicle having the following components: internal combustion engine (VKM), manual transmission (SG), at least one electrical machine (Em), at least one clutch (K) and an energy storage device (ES), and at least one driven axle (HA; VA) are intended to provide maximum efficiency and service life of the components. To this end, a decision is made about which operating modes (AMK) are possible on the basis of a driver input (FW) and operating state, a division is made about which gears (G) are available for the possible operating modes (AMK), so that a larger number of modes (AMGK) are available for selection, operating points which correspond to the driver input are determined for all these modes (AMGK), taking into account the operating state and system state (SZA), the modes (AMGK) are assessed and the mode (AMGK*) which is assessed as being most expedient is selected.
