ABSTRACT:
An engine starting apparatus comprises a starter/alternator assembly operatively coupled to the engine and is 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 an electronic controller provided for controlling the starter/alternator assembly. The starting apparatus further comprises an engine speed sensor for monitoring a rotational speed of the engine that is electrically connected to the electronic controller. 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 engine directly sensed by the engine speed sensor.
