Abstract
An apparatus for controlling a lock-up clutch for direct connection of an engine and an automatic transmission of a motor vehicle, the apparatus including a slip control device for selectively placing said lock-up clutch in one of a fully released state, a fully engaged state, and a partially engaged state, an uphill road detecting device for detecting that a road on which the motor vehicle is running is an uphill road; and a slip control inhibiting device for inhibiting the slip control device from placing the lock-up clutch in the fully or partially engaged state, if the uphill road is detected by the uphill road detecting device, so that undesirable repeated switching of the clutch between the fully released state and the fully or partially engaged state during uphill road running of the vehicle is prevented.
