Claim Text:
1. A method for controlling recharging of a traction battery on a hybrid transmission for a motor vehicle including a heat engine and at least one electrical machine, wherein the at least one electrical machine includes a first electrical machine used as a sole motor-driven power source up to a speed threshold, the method comprising: transmitting, below the speed threshold and when an accelerator pedal of the motor vehicle is pressed, torque to wheels of the motor vehicle via only the first electrical machine and igniting the heat engine without contributing to pull of the motor vehicle; and recharging, below the speed threshold and when the accelerator pedal is not pressed, the traction battery via the first electrical machine while the wheels are decoupled from the heat engine and from the first electrical machine, wherein the speed threshold is a threshold of engagement of the heat engine such that the heat engine does not contribute to the pull of the motor vehicle as long as a speed of the vehicle is below the speed threshold.
