Abstract
A starting apparatus for an internal combustion engine comprises a starter/alternator assembly operatively coupled to the engine and capable of being operated in a starter mode for starting the engine and in a generator mode for generating electric power when driven by the engine. The starter/alternator assembly includes a starter/alternator machine drivingly connected to the engine, an inverter provided for controlling an output of the starter/alternator machine to selectively choose either the starting mode or the generation mode, and a starter/alternator speed sensor for monitoring a rotational speed of a rotor of the starter/alternator machine that is electrically connected to the starter/alternator inverter. A method of controlling the engine starting apparatus controls transition of the starter/alternator assembly from the starter mode to the generator mode in response to the rotational speed of the starter/alternator machine directly sensed by the starter/alternator speed sensor.
