    摘要: If it is determined that an engine has been started, an engine coolant temperature is detected. If the engine coolant temperature is equal to or lower than a threshold value, the catalyst quick warm-up control is started to retard ignition timing, and a signal indicating a command to increase an operate angle is transmitted to a VVLA controller. When a VVT hydraulic pressure is increased to a predetermined value, a signal indicating a command to decrease the operate angle is transmitted to the VVLA controller, and a signal indicating a command to advance open timing of an intake valve is transmitted to a VVT controller so that the open timing of the intake valve is not changed. If the engine coolant temperature is equal to or higher than a threshold value, the catalyst quick warm-up control ends, and the ignition timing is returned to normal timing.

    摘要: 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.
