The invention relates to two methods for operating a motor vehicle driven by an internal combustion engine (VM) and by two electric machines (E1, E2). The motor vehicle has a transmission (G) with two power paths (LP1, LP2) that can be controlled independently of one another. Each power path (LP1, LP2) is coupled via a planetary gear system (P1, P2) to one of the electric machines (E1, E2) and to the input shaft (KW) of the transmission (G) and can be coupled to the output shaft (AW) of the transmission (G) via selectable multiplications (1, 2, 3, 4, 5, 6, R). The aim of the invention is to achieve a more efficient operation of the motor vehicle. To this end, the invention provides, in order to reduce gyratory mechanical power flow between both power paths (LP1, LP2), particularly during boost operation or when recuperating braking energy, the multiplication combination (1, 2, 3, 4, 5, 6, R) is modified or the engine speed is reduced or only one electric machine (E1, E2) is used as a generator. A comfortable operation is additionally achieved in that during the electrical starting, the internal combustion engine (VM) is simultaneously switched on. |
