Patent ID: 8251034

Claim:
A method for controlling a starting system for an engine of a motor vehicle having a pre-spun starter for selective meshing with and starting of the engine, and a controller for controlling the starting of the engine, the method comprising: sensing of a rotational speed of the pre-spun starter; sensing of a rotational speed of the engine; determining whether the sensed speeds of the pre-spun starter and of the engine are within a pre-determined speed difference; regulating the rotational speed of the pre-spun starter to substantially synchronize the rotational speed of the pre-spun starter with the rotational speed of the engine if the sensed speeds of the pre-spun starter and of the engine are not within the pre-determined speed difference; engaging the pre-spun starter with the engine; and applying torque by the pre-spun starter to the engine for starting the engine.
