method of assisting gear shifting in a gearbox of a powertrain provided with a heat engine (1) coupled to the gearbox (4) by an input clutch (6) which, when disengaged, interrupts the transmission of torque from the engine (1) to the gearbox (4) during gear shifting, and an assisting electric machine (3) of which the torque is exerted on a shaft permanently coupled to the crankshaft (2) of the heat engine, according to which the electric machine is used to control the rotational speed of the heat engine before the clutch is engaged in the new engaged speed, characterised in that the electric machine (3) is controlled such that the rotational speed of the heat engine (1) reaches a target speed based on the type of shift engaged. |
