Abstract
A fluid pressure control device including a first pump actuated by power from a motor; a pressure regulator that regulates a discharge pressure from the first pump; a second pump actuated by electric power; a switcher opening a first path extending from the pressure regulator to a fluid pressure chamber of a friction engagement element, and blocking a second path extending from the second pump to the fluid pressure chamber of the friction engagement element, when the signal pressure is equal to or more than a set pressure, and the switcher blocking the first and opening the second paths when the signal pressure is less than the set pressure; and a control that controls the second pump and the fluid supply unit to supply the fluid regulated by the pressure regulator to a destination different from the fluid pressure chamber of the friction engagement element when the motor is stopped.
