A lockup clutch control apparatus includes a power unit, an automatic transmission, a torque converter, a lockup clutch, an input shaft connected to the power unit, a first output shaft for transmitting the driving force to the automatic transmission; and a second output shaft for transmitting the driving force from the automatic transmission. When a power unit rotation speed or a first output shaft rotation speed becomes equal to, or lower than a first rotation speed, the lockup pressure supplied to the lockup clutch is controlled at a first pressure reduction speed to a target reduced pressure value which is obtained within a range at which the lockup pressure can be controlled. When the lockup pressure becomes the target reduced pressure value, the lockup pressure is reduced at a second pressure reduction speed, which is lower than the first pressure reduction speed, until the lockup clutch starts slipping. |
