<P>PROBLEM TO BE SOLVED: To further properly suppress the simultaneous engagement of a plurality of hydraulic frictional engaging elements which are not simultaneously engaged with one another in a normal time. <P>SOLUTION: This hydraulic control device 50 cuts off the supply of C2-solenoid pressure Pslc2 to a brake B3 when the brake B3 is not engaged without supplying the C2-solenoid pressure Pslc2 from a C2-linear solenoid valve SLC2 to the brake B3 which is not simultaneously engaged with a brake B1 in a normal time, supplies line pressure PL to a B3-switching valve 70 as signal pressure for forming a cut-off discharge state capable of discharging hydraulic pressure from the brake B3, and supplies modulator pressure Pmod of lower pressure than the line pressure PL to the B3 switching valve 70 as signal pressure for forming a communicating state capable of supplying the C2-solenoid pressure Pslc2 to the brake B3 when engaging the brake B3 by supplying the C2-solenoid pressure Pslc2 to the brake B3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
