ABSTRACT:
A starting system and a method for starting an automotive internal combustion engine, the method and apparatus being capable of improving the starting ability of the engine. The starting system includes a starter motor, a means for measuring a crankshaft angle of the engine, and a control means which controls the entire system. The system is initiated by a start command being input thereto. The system, i.e., the control means, then preliminarily drives the starter motor in a reverse direction in a predetermined relation to the start command so that a load torque on the starter motor is reduced. Then, the control means of the system determines whether the reverse rotation of the starter motor has attained a predetermined value. Then, the starter motor is driven in a forward direction when the reverse rotation has attained the predetermined value.
