Abstract
A starting control unit integrally includes a current suppression resistor connected in series with an output contact of an electromagnetic shift relay provided on a starter motor, a short-circuiting relay that short-circuits the current suppression resistor with a short-circuiting contact thereof, and a timer circuit that closes the short-circuiting contact at a predetermined time instant when a starting current decreases in response to the operation of a starting command switch. An excitation coil of the short-circuiting relay is supplied with electric power directly from a vehicle battery by way of one of the terminals of the current suppression resistor, a reverse connection protection device, and a driving transistor, excluding the starting command switch. A suppression starting current for the starter motor flows in the current suppression resistor during the time period obtained by adding a delay setting time Tof the timer circuit and a tfrom a time instant when the excitation coil is de-energized to a time instant when the short-circuiting contact is returned to be closed.
