PROBLEM TO BE SOLVED: To allow backward travelling even when an abnormality occurs in a shift position sensor, in a hydraulic control device generating line pressure by using hydraulic pressure of any one of a plurality of pressure regulating valves as signal pressure.SOLUTION: When it is determined that an abnormality occurs in a shift position sensor, and in a state where lock-up should be released (in steps S150, S170), a solenoid valve S1 is controlled to generate solenoid pressure Ps1 as selector signal pressure to a C2/B3 selector valve (S180), a C2 linear solenoid valve SLC2 is controlled to output C2 solenoid pressure Pslc2 (S190, S200), and at least the C2 solenoid pressure Pslc2 is supplied to a primary regulator valve 51 through a shuttle valve 54 as signal pressure, so that line pressure PL can be generated by the primary regulator valve 51. |
