PROBLEM TO BE SOLVED: To provide an oil pressure control system which can supply oil pressure without deteriorating the fuel efficiency.SOLUTION: An oil pressure control system includes a first connection/break mechanism 1 transmitting the rotation of a drive shaft 11 to a pump shaft 51, and a second connection/break mechanism 2 transmitting the rotation of an input shaft 12 to the pump shaft 51. The second connection/break mechanism 2 includes a speed increase mechanism 62 which increases the rotation speed of the input shaft 12 and transmits the rotation to the pump shaft 51. When the rotation speed of the drive shaft 11 is larger than that of the input shaft 12, the second connection/break mechanism 2 transmits the rotation of the input shaft to the pump shaft 51. |
