Abstract
A starter control system is comprised of a starter motor, a control circuit for controlling the starter motor to rotate at a preliminary rotation speed that is high enough to engage a pinion with an engine for a predetermined time and low enough to suppress a harsh noise caused when the pinion engages the engine and, thereafter, at a normal rotation speed that is high enough to start the engine, and a control circuit for changing the preliminary rotation speed according to an engine temperature. The starter control system is effective to reduce noises that are caused when the engine is started by an economy-run system.
