摘要
An apparatus for controlling a slip speed of a lock-up clutch interposed between an engine and an automatic transmission of a motor vehicle, the apparatus including a slip control device for effecting a deceleration slip control of the lock-up clutch during vehicle deceleration for controlling the slip speed of the clutch, a detector for detecting a currently established position of the transmission, or an operation of a vehicle braking system or an air conditioner, and a control terminating device for substantially terminating the deceleration slip control of the clutch when the speed of the transmission input shaft has been lowered to a threshold value which is determined depending upon the speed ratio of the currently established position of the transmission, or whether the braking system or air conditioner is in operation or not.
