Abstract
A lock-up clutch controller includes a lock-up clutch and one or more processors. The lock-up clutch is configured to directly couple an engine to an automatic transmission without via a torque converter interposed between the engine and the automatic transmission. The one or more processors are configured to control engagement and disengagement of the lock-up clutch. The one or more processors are configured to, in the middle of the engagement of the lock-up clutch, set a lower limit value of engine torque based on engagement torque of the lock-up clutch, and control the engine to inhibit the engine torque from falling below the lower limit value.
