Abstract:
1. A hybrid vehicle, comprising: an internal combustion engine; an electric motor; an electric storage device providing and receiving electric power to and from the electric motor; an automatic transmission including a first input shaft, a second input shaft, and a coupling element which couples the first input shaft or the second input shaft selectively to an output shaft, wherein a driving force of the internal combustion engine is selectively transmitted to the first input shaft via a first clutch, the first input shaft is connected to the electric motor, the driving force of the internal combustion engine is selectively transmitted to the second input shaft via a second clutch, and a motive power output from the internal combustion engine and the electric motor is shifted and transmitted to the output shaft; a zone distinguishing element detecting a remaining capacity of the electric storage device, and distinguishes, on the basis of the detected remaining capacity, a standard zone, a discharge limited zone in which the remaining capacity is smaller than the standard zone, and a discharge prohibited zone in which the remaining capacity is smaller than the discharge limited zone; and an idling stop control element controlling charging of the electric storage device, wherein when an idling stop request is generated and the zone distinguished by the zone distinguishing element is the discharge limited zone or the discharge prohibited zone, the idling stop control element sets the first clutch to a connected state while maintaining driving of the internal combustion engine so as to rotate the first input shaft, and thereafter, when an idling stop release request is generated and the zone distinguished by the zone distinguishing element is the standard zone, the idling stop control element controls to start the vehicle while setting the internal combustion engine to a stopped state and the electric motor to a driving state, when an idling stop release request is generated and the zone distinguished by the zone distinguishing element is the discharge limited zone, the idling stop control element controls to start the vehicle by driving the electric motor while continuing driving of the internal combustion engine and maintaining the first clutch in an interrupted state, and when an idling stop release request is generated and the zone distinguished by the zone distinguishing element is the discharge prohibited zone, the idling stop control element control to start the vehicle by continuing driving of the internal combustion engine and setting the first clutch to the connected state.
