A method for controlling the torque available during the ratio changes of a drive train consisting of a heat engine (Mth) connected to a first input shaft (4) of a gearbox (1) that can transmit the torque of same to the wheels at different transmission ratios, a first electric machine (ME) connected to a second input shaft thereof, and a second electric machine (2) connected alternately to the first or second input shaft of the gearbox, characterised in that, during the changes in the transmission ratio of the heat engine (Mth), the second electric machine (2) operates in regenerative mode and transmits all of the electric power of same to the first electric machine (ME) that uses it to compensate for the reduction in torque at the driven wheel resulting from the temporary decoupling of the heat engine during the change in ratio of same.
A method for controlling the torque available during the gear shifts of a powertrain made up of a combustion engine (CE) connected to a first input shaft (4) of a gearbox which can transmit its torque to the wheels at different transmission ratios, of a first electric machine (EM) connected to a second input shaft (6) of this gearbox, and of a second electric machine (HSG) connected alternately to the first or to the second input shaft of the box,
