Abstract: 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 (Emi), at least one clutch (Kj) 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 (Gj) 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.

Abstract: With a method and a device for controlling the hybrid drive of a motor vehicle, having the components: internal combustion engine (ICE), shift transmission (ST), at least one electric machine (EMi), at least one clutch (Cj) and an energy store (ES), and at least one driven axle (RA; FA), it is sought to obtain the maximum efficiency and service life of the components. For this purpose, it is decided which operating modes (AMK) are possible on the basis of the driver demand (DD) and of the operating state, for the possible operating modes (AMK), it is decided which transmission gears (Gj) are possible, such that a greater number of modes (AMGK) are available for selection, for all of said modes (AMGK), operating points corresponding to the driver demand are determined taking into consideration the operating state and system state (SSA), the modes (AMGK) are evaluated, and the mode (AMGK*) that is evaluated as being the most favorable is selected.
