ABSTRACT:
A control system for distributing braking forces applied to left and right wheels in an automotive vehicle, comprises two fluid pressure control valves, normally controlling a left-wheel brake fluid pressure distribution between front and rear-left wheels and a right-wheel brake fluid pressure distribution between front and rear-right wheels such that a rear-wheel brake fluid pressure is less than a front-wheel brake fluid pressure in a range above a respective critical fluid pressure at which the brake fluid pressure distribution between front and rear wheels is essentially varied, a lateral acceleration sensor for monitoring a degree of turn of the vehicle, and a set of reversible motors and return springs employed in each fluid pressure control valve for varying the respective critical fluid pressures independently of each other depending on the degree of turning such that the critical fluid pressure of the outer-wheel side is set at a higher level than the critical fluid pressure of the inner-wheel side.
