An electric vehicle includes an electric motor, a power storage device, a control device, and a refrigerant circuit. The refrigerant circuit includes a compressor, an outdoor heat exchanger, a first indoor heat exchanger, a first expansion valve, a second expansion valve, and a second indoor heat exchanger. The control device repeats an operation of performing the other of a first operation and a second operation after performing one thereof when a remaining capacity of a power storage device is equal to or larger than a predetermined value. In the first operation, the first expansion valve is not decompressed and the second expansion valve is decompressed. In the second operation, the first expansion valve is decompressed and the second expansion valve is not decompressed.

Electric vehicle

A stop control system for a vehicle is provided, which is capable of stably performing cranking for restarting an internal combustion engine and positively preventing the vehicle from moving by properly increasing a braking force of the vehicle, during an idle stop. In the stop control system for a vehicle according to the present invention, the engineis cranked by the starter motorusing the power supplied from the battery, when restart conditions are satisfied (stepin FIG.). Further, the stop control system includes a hydraulic pumpdriven by the power supplied from the battery, for increasing the braking force of the vehicle V. During a stop of the vehicle V, it is determined whether or not the braking force of the vehicle V needs to be increased (FIG.), and the hydraulic pumpis controlled according to a determination result. Further, in a case where it is determined that the braking force of the vehicle V needs to be increased, the operation of the hydraulic pumpis inhibited for a predetermined time period during cranking (stepsin FIG.).

Stop control system for vehicle

A stop control system for a vehicle, which is capable of positively preventing movement of a vehicle by positively increasing a braking force of the vehicle during an idle stop. In the stop control system for a vehicle of the present invention, the engineis cranked by a starter motorusing power supplied from the batterywhen restart conditions are satisfied during an idle stop (stepin FIG.). Further, the stop control system includes a hydraulic pumpdriven by power supplied from the battery, for increasing the braking force of the vehicle V. During a stop of the vehicle V, when it is determined that the braking force of the vehicle V needs to be increased (F_BFREQ=1), the hydraulic pumpis activated. Further, if the restart conditions are satisfied during operation of the hydraulic pump, the cranking is inhibited to continue the operation of the hydraulic pump(stepstoin FIG.).
