Abstract
When a traveling state is in an engagement range of a lock-up clutch, an ECU executes a program including a step of executing slip control if preconditions are satisfied and learning start conditions are satisfied, a step of updating a learning value if an output value is not greater than an FF control value+α or not smaller than the FF control value+β, and a step of engaging the lock-up clutch.
