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.
