Abstract
An electric starter system for an internal combustion includes a pinion gear, a pinion solenoid coupled to the pinion gear, a starter motor that is selectively connectable to the flywheel of the engine via the pinion gear, and a controller in communication with the pinion solenoid and the starter motor. In response to an engine auto-stop signal, the controller is configured to translate the pinion gear into contact with the flywheel and the motor, and cause rotation of the engine crankshaft to a predetermined crank angle. In response to an engine auto-start signal, the controller is configured to command delivery of motor torque from the starter motor, through the pinion gear, and to the flywheel for a duration sufficient for starting the engine.
