<p><P>PROBLEM TO BE SOLVED: To provide a hydraulic control device capable of controlling generation of a shock when engaging a lock-up clutch. <P>SOLUTION: This hydraulic control device includes a fluid transmitting device 3 for transmitting power by using kinetic energy of a fluid between a first rotary member 8 and a second rotary member 9, a lock-up clutch 11 for transmitting power to the friction force between the first rotary member 8 and the second rotary member 9, a selector valve 26 for controlling engagement/release of the lock-up clutch 11, and a control hydraulic pressure generating device 41 for outputting the control hydraulic pressure for controlling operation of the selector valve 26 by adjusting the pressure of the oil to be input. Switching devices 49 and 50 are provided to warm the oil to be input to the control hydraulic pressure generating device 41 if the temperature of the oil to be input to the control hydraulic pressure generating device 41 is below a predetermined temperature, and not to warm the temperature of the oil to be input to the control hydraulic pressure generating device 41 if the temperature of the oil to be input to the control hydraulic pressure generating device 41 exceeds a predetermined temperature. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
