<p>An adaptive braking system in which the speed of each wheel on an axle is independently sensed but the braking pressure of both axle wheels is controlled during adaptive braking by a single brake pressure modulator. The speed of each wheel is sensed by an individual wheel speed sensor which in turn feeds an individual control logic circuit for its respective wheel. A control logic circuit normally generates signals for attenuating and subsequently restoring brake pressure on the wheel whose wheel speed sensor is feeding it. In the present invention, the control logic circuits are connected to a brake pressure modulator through a gating circuit so that brake pressure on both wheels is attenuated only if both control logic circuits generate signals to attenuate brake pressure and brake pressure is subsequently restored only if both control logic circuits require that brake pressure be restored. The gating circuit also permits the wheel having the highest speed to control adaptive braking in case the ratio of the speed of the low speed wheel with respect to the speed of the high speed wheel drops below a predetermined level.</p> |
