Abstract
In a slip control system for a vehicle a slip ratio of driving wheels of the vehicle is detected, and the slip of the driving wheels is controlled to converge on a predetermined target slip ratio when the slip ratio of the driving wheels exceeds a predetermined threshold slip ratio. When the vehicle is running a rough road, the threshold slip ratio is increased. The running condition of the vehicle is detected and increase of the threshold slip ratio is inhibited depending on the running condition of the vehicle.
