Abstract:
An idling stop control apparatus mounted on a vehicle, wherein auxiliary machinery is driven by means of either one of an internal combustion engine and an electric motor, and an output shaft of said internal combustion engine and an output shaft of said electric motor are linked with each other via a coupling mechanism that is coupled to connect said internal combustion engine with said electric motor and is released to disconnect said internal combustion engine from said electric motor, said coupling mechanism being released and said auxiliary machinery being driven by means of said electric motor via a transmission belt while said internal combustion engine is at a stop, said idling stop control apparatus comprising:a decision unit that determines whether a driving stop condition or a driving restart condition of said internal combustion engine is fulfilled; a braking load specification unit that, when the driving restart condition of said internal combustion engine is fulfilled, specifies a braking load to be applied to said electric motor, in order to reduce electric motor velocity or number of revolutions of said electric motor according to a kinetic energy absorbing state of said transmission belt; a drive stand-by unit that, when the driving restart condition of said internal combustion engine is fulfilled and said coupling mechanism is released, causes said output shaft of said internal combustion engine to be coupled with said output shaft of said electric motor via said coupling mechanism after application of the specified braking load to said electric motor; and an internal combustion engine operation control unit that executes a series of processing to restart operation of said internal combustion engine after said internal combustion engine is coupled with said electric motor via said coupling mechanism.
