Providing a control device for controlling a vehicle oil supply device to reduce a period while a mechanical oil pump and an electric oil pump are driven in an overlapping manner in the vehicle oil supply device including the mechanical oil pump and the electric oil pump. The electric oil pump control means 84 drives the electric oil pump 32 during stop of the mechanical oil pump 30 and stops the electric oil pump 32 based on a load increase ofthe electric oil pump 32 after the start of driving of the stopped mechanical oil pump 30. Since the oil from the electric oil pump 32 is held back via the check valve 56 by the mechanical oil pump output oil pressure Pmop, a rise in output oil pressure of the mechanical oil pump 30 is directly reflected by a load increase of the electric oil pump 32. Therefore, while a shortage of oil supply such as a temporary drop in oil pressure is suppressed in the hydraulic control circuit 20, the pump overlap drive period can be made shorter. |
