Abstract:
A hydraulic circuit (30) for a vehicle equipped with an EHPS system (10) and an oil pressure supply system (20), wherein the oil pressure supply system (20) is equipped with a cylinder (32), which stores oil at a second oil pressure P2 while a vehicle (1) is travelling, and which supplies the stored second oil pressure P2 to a clutch circuit (27) as a third oil pressure P3 when oil pressure is supplied while the second oil pressure P2 is being stored. In addition, a connecting line that connects the cylinder (32) and the EHPS system (10) is provided to enable a first oil pressure P1 to be supplied to the cylinder (32) when the vehicle is started and a motor (12) is driven. Thus, it is possible to reduce the amount of power consumed during idling stop, and to reduce the amount of time required to recover from idling stop.
