ABSTRACT:
A slip control apparatus is designed such that an output from the engine is rapidly reduced to a set limit value by a feed-forward control when a friction coefficient on pavement gets large and the engine output reduced to the set limit value is then returned to a set return value larger than the set limit value by the feed-forward control. After returning to the set return value, the engine output is subjected to feed-back control so as to turn a slip value of the driven wheel to a target value. The set limit and return values can be changed in accordance with the friction coefficient on pavement and a vehicle speed. The set limit and return values can be corrected in a direction in which they become larger when the slip value gets larger on account of the upshifting of the transmission.
