Abstract

A vehicle control system is provided which is used in a vehicle equipped with an engine as a drive power source and works to establish engagement of a pinion of a starter motor with a ring gear mounted on a rotational axis of the engine and then actuate the starter motor to start the engine. The vehicle control system executes a preset mode to move the pinion to achieve the engagement with the ring gear when the rotation speed of the engine has dropped below a given threshold value. The threshold value is determined as a function of speed of the vehicle, thereby alleviating a driver's perception about unwanted mechanical noise arising from impact the pinion on the ring gear upon the engagement therebetween.
