Patent ID: 8205697

Claim:
Control method for a hybrid vehicle comprising: a combustion drivetrain comprising a front wheel axle unit, a heat engine coupled by a coupling member to a gearbox intended to transmit vehicle traction power for various gearbox reduction ratios through a front transmission to the front wheel axle unit, and at least one front electric machine coupled to the heat engine, used at least for restarting it, an electric drivetrain comprising a rear wheel axle unit, and at least one rear electric machine mechanically coupled to the rear wheel axle unit through a rear transmission, at least one electrical power network connecting the rear electric machine to electrical energy storage means, a control means for controlling the combustion drivetrain, the electric drivetrain, and the electrical energy storage means, for taking all the vehicle life scenarios into account, wherein the combustion drivetrain, the electric drivetrain, and the energy storage means are controlled via the control means in order to transmit power provided by the combustion drivetrain to the electric drivetrain, via the road on which the vehicle is traveling, for recharging the energy storage means, and the method comprises, when the vehicle is in motion and being driven by the heat engine, controlling the rear electric machine so as to draw part of the vehicle's traction power, supplied by the vehicle heat engine, through the rear wheel axle unit of the vehicle, while maintaining the speed and/or acceleration of the vehicle.
