Because an EOP starts operating from when a decrease in discharge flow rate of an MOP is predicted or detected, a PL actual pressure that should be obtained with a PL command pressure set to a value for a required transmission torque is more easily maintained even when the discharge flow rate of the MOP becomes insufficient. After a lapse of a predetermined period of time from the start of operation of the EOP, the PL command pressure is temporarily set to a value higher than the value for the required transmission torque, and a regulator valve is controlled to operate to close a drain port. Therefore, the operation of the EOP in a high PL actual pressure is reduced, and a delay in response of a pressure regulating operation of the regulator valve in the process of reduction of the discharge flow rate of the MOP is reduced.
