Abstract (en)
[origin: WO2019081182A1] Method for monitoring the start time of a powertrain heat engine (GMP) of a hybrid vehicle during the transition from a current electrical drive train state, wherein an electrical machine alone provides traction to the vehicle, to a target hybrid drive chain state, wherein the traction of the vehicle is ensured simultaneously by at least one heat engine and one electrical machine, characterised in that: - the force to be achieved by the GMP (FORC_PWT_REQ) is determined, - the force gain (FORC_TRAC_DIF) that the electrical machine is not able to develop in order to achieve the entire force (FORC_PWT_REQ) of the GMP on the current ratio is determined, - the force deviation (FORC_TRAC_DIF) is compared to a reference force gain (FORC_DIF_ALLOW).
