Abstract

A drive system for a plug-in hybrid motor vehicle, having an internal combustion engine, an electric motor, a high-voltage source, in particular a high-voltage battery which has a minimum setpoint state of charge, a generator, a clutch, at least one transmission, at least one drive axle and a control unit, with the internal combustion engine being mechanically connected to at least one drive axle, with a first drive mode, “depleting mode”, and a second drive mode, “sustaining mode”, being provided in the control unit, with a third drive mode, “increasing mode”, which can be manually activated being provided, said third drive mode providing a load point increase at the internal combustion engine in such a way that the high-voltage source can be charged during driving and therefore the first drive mode can be activated.
