Abstract (en)

[origin: FR2770808A1] The invention concerns a motor vehicle with dual engine system comprising an electric engine and a heat engine, wherein a central management unit executes a first task (1200) including the determination of a torque which each engine must provide to supply an engine torque in conformity with the torque requested by the driver, and wherein the heat engine can be stopped. The invention is characterised, at least for some operating modes, the central unit executes a second task (1100) during which the decision to stop or to start the heat engine is taken, and the first and second tasks are executed in parallel, the execution frequency of the second task being less frequently operated than the first.
