Abstract
Method for control of a multi-phase, reversible, rotating electrical machine, called alternator/starter, for a motor vehicle with a heat engine capable of operating either as an electrical generator—alternator mode—or as an electric motor, especially in order to start the heat engine, characterised in that, during operation in electric-motor mode, the said machine is driven according to two modes corresponding to different speed/torque characteristic curves, namely a first mode, called starter mode, making it possible to drive the heat engine of the vehicle in order to start it with high torques for low speeds, while the second mode, called auxiliary-motor mode, makes it possible to drive at least one power-consumer unit, such as an accessory, and/or the heat engine, at higher speeds and lower torques than those of the first mode.
