Claim Text:
1. A hydraulic pressure supply system for supplying hydraulic pressure to a hydraulic clutch which connects and disconnects between an internal combustion engine that is installed on a vehicle as a motive power source and is stopped when predetermined stop conditions are satisfied and restarted when predetermined restart conditions are satisfied, by a starter device that is not used as a motive power source of the vehicle, and drive wheels of the vehicle, wherein the stop conditions include a condition that a speed of the vehicle is not higher than a predetermined stop vehicle speed which is larger than 0, the hydraulic pressure supply system comprising: a first hydraulic pressure supply device that uses the engine as a motive power source, and supplies hydraulic pressure to the clutch; a second hydraulic pressure supply device that supplies hydraulic pressure to the clutch by being driven by a motive power source other than the engine; detection means for detecting at least one of the speed of the vehicle and a rotational difference parameter indicative of a difference in rotational speed between an output shaft of the clutch and an input shaft of the clutch; and hydraulic pressure control means for controlling clutch supply hydraulic pressure which is hydraulic pressure supplied to the clutch, according to at least one of the vehicle speed and the rotational difference parameter, by said detection means, when the restart conditions of the engine have been satisfied.
