ABSTRACT:
A lock-up clutch slip control system for controlling a lock-up clutch, which is arranged in parallel with a hydraulic power transmission for connecting a prime mover and a speed change unit, selectively into a slip state. It is decided whether or not a slip control of changing the lock-up clutch from a complete apply state to a slip state is to be executed according to the operation of lowering the output of the prime mover. The output of said prime mover is changed to suppress the output fluctuation of the prime mover when it is decided that the slip control of the lock-up clutch is to be executed.
