Patent ID: 8506454

Claim:
A fluid pressure control device for an automatic transmission that is mounted on a vehicle including a motor capable of intermittent operation and that transfers power from the motor to an axle side with a speed of the power changed via a friction engagement element actuated by a fluid pressure, comprising: a first pump actuated by the power from the motor; a pressure regulator that regulates a discharge pressure from the first pump; a second pump actuated by supply of electric power; a switcher actuated by a signal pressure generated on the basis of a fluid pressure regulated by the pressure regulator, the switcher opening a first path, which extends from the pressure regulator to a fluid pressure chamber of a friction engagement element for starting, and blocking a second path, which extends from the second pump to the fluid pressure chamber of the friction engagement element for starting, when the signal pressure is equal to or more than a set pressure, and the switcher blocking the first path and opening the second path when the signal pressure is less than the set pressure; a fluid supply unit that supplies the fluid pressure regulated by the pressure regulator to a destination different from the fluid pressure chamber of the friction engagement element for starting; and a control section that controls the second pump so as to be actuated and controls the fluid supply unit so as to supply the fluid pressure regulated by the pressure regulator to the destination when the motor which has been in operation is stopped.
