Abstract
In a hydraulic circuit for a vehicle including an electric pump power steering system (EHPS), a hydraulic pressure supply system including a cylinder to store a second hydraulic pressure while a vehicle is traveling and supply the stored second hydraulic pressure to a clutch circuit as a third hydraulic pressure when being supplied with hydraulic pressure after storing the second hydraulic pressure. The hydraulic circuit also includes a connecting path to connect, at the start of the vehicle, the cylinder and the EHPS system to allow a first hydraulic pressure to be supplied to the cylinder by drive of a motor. It is therefore possible to reduce electric power consumed during idling stop mode and shorten a recovery time from the idling stop mode.
