<p><P>PROBLEM TO BE SOLVED: To reduce flow-rate consumption to the minimum during non-use of a linear solenoid valve used for controlling engagement of a friction engagement element while securing responsiveness of the linear solenoid valve. <P>SOLUTION: In linear solenoid setting processing, a linear solenoid mode switching means 506 switches the non-use linear solenoid valve in the hydraulic control apparatus 6 from a normal hydraulic control mode to a consumption current reducing mode, when an oil temperature TATF of hydraulic fluid obtained by an oil temperature obtaining means 502 is a prescribed oil temperature or higher, and when a speed Ne of an engine 1 obtained by an engine speed obtaining means 503 is a prescribed speed or less. As such, by switching a current value supplied to the target non-use linear solenoid valve by the linear solenoid mode switching means 506, a pressure-adjusted state is attained in which the flow-rate consumption of the linear solenoid valve is reduced to the minimum, and deterioration of control hydraulic pressure can be suppressed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
