摘要:
In a traction control system for motor vehicles, a plurality of threshold values which are higher than the vehicle speed (equal to the non-driving wheel speed) are set up; the wheel speed as increasing or decreasing is compared with the above-mentioned plurality of threshold values to effect buildup or reduction of the brake fluid pressure; and holding of the brake fluid pressure is effected on the basis of a variation in the acceleration/deceleration of the driving wheel; in the case where the holding control mode in which the brake fluid pressure is held, persists for a predetermined time period or longer when the driving wheel speed is higher than a specific one of the above-mentioned plurality of threshold values, the holding control mode is switched to buildup control mode.
