Abstract
A wheel slip control system is provided which includes a drive wheel speed detection device for detecting the speed of drive wheels driven by an internal combustion engine, a follower speed detection device for detecting the speed of follower wheels, a rotation difference computing device for computing the ratio of a detected value of the drive wheel speed detection device to a detected value of the follower speed detection device if the absolute change rate of the detection value of the drive wheel speed detection device is less than a fixed value, a drive wheel speed correction device for correcting a detected value of the drive wheel speed detection device using the wheel speed ratio computed by the rotation difference computing device, a slip determination device for determining if a slip is occurring by comparing the value of drive wheel speed corrected by the drive wheel speed correction device with the detected value of the follower speed detection device and an output power control for controlling the output power of the internal combustion engine according to the determination of the slip determination means.
