Abstract (en)

[origin: WO2019025306A1] The invention relates chiefly to a method for compensating for acyclic behaviour of a motor vehicle heat engine (12), the heat engine (12) belonging to a powertrain (10), characterized in that the said method involves: – a step of measuring a physical parameter associated with the rotation of a crankshaft of the heat engine (12), the step of measuring the physical parameter being performed by means of a sensor (27, 27') located between the mechanical damper (20) and the heat engine (12), – a step of determining, from the measured physical parameter, a variation in torque associated with the acyclic behaviour of the heat engine (12), taking account of a transfer function caused by the mechanical damper (20), – a step of subtracting this variation in torque from a reference setpoint torque (Cref) of the rotary electric machine (17) in order to determine a control setpoint torque (Cref'), – a step (106) of operating the rotary electric machine (17) in order to obtain the control setpoint torque (Cref').
