Abstract
An engine starter system includes a starter including a multi-phase brushless electric motor and an electronic commutator assembly. A controller includes an instruction set that is executable in response to a command to execute an engine starting event. Operation includes determining a desired starting profile, controlling the starter to engage a rotatable member of the engine, and monitoring the rotational speed of the electric motor via a rotor position sensing circuit. The starter inverter is dynamically controlled to control the electric motor to spin the rotatable member of the internal combustion engine responsive to the desired starting profile, including dynamically controlling the starter inverter to control the electric motor to control the spin of the engine responsive to the desired starting profile to prevent occurrence of an engine speed flare event during the engine starting event.
