The invention relates to a motor vehicle integrating a hybrid drive train comprising: a heat engine (Mt); one or more batteries (B); an electric motor (M/Ge) operating either as an engine using power available in the batteries (B), or as a generator to recharge said batteries; a device (Epi) coupling the heat engine (Mt), the electric motor (M/Ge) and the wheels (R) of the vehicle in order to combine the power of said engine, said motor and said wheels; a control unit (UC) monitoring the operation of the heat engine (Mt) and the electric motor (M/Ge), said system operating in hybrid mode or in "all electric" mode, characterised in that: the control unit (UC) is connected to a means (13) for entering a route to be travelled; the control unit (UC) monitors the heat engine (Mt) and the electric motor (M/Ge) according to the characteristics of the route entered, in order to distribute the power from said heat engine and said electric motor, so that the power available in the batteries (B) reaches a desirable discharge value at the end of said route.
