Abstract

The invention generally relates to a method for compensating for aperiodic behavior in a heat engine (12) of a motor vehicle, the method comprising: - the step of measuring the angular position of a shaft (17.3) or rotor (17.2) using a sensor (27) , the sensor is installed between the mechanical damper (20) and the gearbox (13), where the rotor (17.2) of the rotating electrical machine (17) is arranged, ‑ according to the measured angle of the shaft (17.3) or the rotor (17.2) position, step of determining the torque change related to the aperiodic behavior of the heat engine, - according to the sign of this torque change, subtracting this torque change / this torque change from the reference torque setpoint (Cref) of the rotating electrical machine (17) Variations are added to the reference torque setpoint (Cref) of the rotating electrical machine (17) to determine the control torque setpoint (Cref'), ‑steps of controlling the rotating electrical machine (17) to obtain the control torque setpoint .

Description

technical field [0001] The present invention relates to a method of compensating for irregularities in a heat engine by rotating electrical machines. Background technique [0002] The traction chain of a motor vehicle includes, in a known manner, a heat engine, which is coupled to a gearbox via a clutch. The gearbox is mechanically connected to the wheels via a differential. Typically, the crankshaft of a heat engine is connected to a mechanical damper, which in turn is connected to a clutch to transfer energy to the wheels through a gearbox. [0003] In addition, rotating electric machines can be implanted in the traction chain to improve the energy balance of the vehicle. The electric machine can be operated in motor mode to ensure traction of the vehicle alone or in combination with the heat engine in order to ensure assisted traction. The electric machine may also operate in a generator mode to provide energy to the vehicle's battery and / or grid-connected loads. [0...
