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 generatoralternator modeor 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.
