METHOD AND DEVICE FOR MONITORING THE USE OF DRIVING MACHINES OF A HYBRID VEHICLE IN COMPLEMENT OF THE THERMAL MOTOR, ACCORDING TO THEIR EFFICIENCY

摘要

The invention relates to a device (DC) for controlling the use of torque produced by a heat engine (MT), coupled to a gearbox (BV), and at least two prime movers (MM1-MM2) of a power train of a hybrid vehicle (V), according to a torque required depending on the driver's willingness to act. Said device (DC) is arranged, when the torque supplied at the output of the gearbox (BV) and resulting from a maximum torque produced by the heat engine (MT) is less than the torque required at a given moment, so as to determine the efficiency generated by the prime movers (MM1-MM2) at said given moment, then to command the use of at least part of the torque produced by the prime mover generating the highest determined efficiency in addition to the maximum torque produced by the heat engine (MT) in order to obtain the required torque.
