Abstract
A traction control system comprising a slip control circuit connected between a slip detector circuit and a hydraulic brake control mechanism. Normally, the slip control circuit acts to cause the brake control mechanism to controllably actuate brakes on vehicle wheels so as to maintain the slip rates of the wheels less than a predetermined limit. The slip control circuit is disabled, however, by a wheel liftoff detector circuit as the latter detects, when the vehicle is rounding a curve, the lifting of the inside wheels off the road surface. At the same time the wheel liftoff detector circuit causes a decrease in engine power through reduction of throttle opening, thereby minimizing the danger of vehicle turnover.
