ABSTRACT:
A lock-up clutch control during a gear shifting is disclosed. A ratio of an input revolution speed of an automatic transmission to an output revolution speed thereof is used to determine whether the gear shifting is in progress. If this is the case, the lock-up clutch is released. A timer is provided which starts measuring time after occurrence of a command for such gear shifting. If the length of time becomes greater than a predetermined value, the lock-up clutch is released.
