Provided is an oil pressure supply device for a vehicle, with which oil pressure can be supplied quickly to a drive transmission device when an internal combustion engine is restarted after automatic stopping of the engine, and with which the service life of an accumulator for supplying the oil pressure to the drive transmission device can be extended. This oil pressure supply device is equipped with: an oil pump which has the internal combustion engine as a drive power source, and is connected to the drive transmission device via an oil passage, thereby supplying oil pressure to the drive transmission device to operate the drive transmission device; an accumulator connected to the oil passage and capable of accumulating oil pressure; and a switching valve, which is capable of connecting the accumulator and the oil passage by opening during operation of the internal combustion engine, and is capable of blocking the connection by closing during automatic stopping of the internal combustion engine. When it is determined that the internal combustion engine has been stopped manually by turning off the vehicle's ignition switch (step 1: No), a control for use during manual stopping is executed to open the switching valve (step 8). |
