Abstract
The technique of the present invention reduces or even omits potential shocks and vibrations arising due to the coupling action of a coupling mechanism at the time of starting an internal combustion engine, and ensures a quick restart of the internal combustion engine. In a vehicle with an idling stop control apparatus of the present invention mounted thereon, a control unit inputs an inverted phase current Eon, which is determined according to the energy absorbing state of a transmission belt, into an auxiliary machinery driving electric motor, so as to brake rotations of the auxiliary machinery driving electric motor. After the input of the inverted phase current Eon into the auxiliary machinery driving electric motor, the control unit couples an electromagnetic clutch to link a crankshaft of the internal combustion engine with the auxiliary machinery driving electric motor. The value of the inverted phase current Eon is varied according to the energy absorbing state of the transmission belt. The braking force of the auxiliary machinery driving electric motor is thus varied according to the energy absorbing state of the transmission belt.
