Abstract

A method for restarting an engine of a vehicle includes stopping the vehicle and holding the vehicle stationary, reducing engine speed, increasing a rate of reduction of engine speed, if engine speed is less than a reference speed when a desired restart of the engine is indicated, and initiating an engine restart when engine speed is substantially zero.
