An anti-lock brake system having an electronic control responsive to wheel speed sensors associated with each wheel of the vehicle. The electronic control generates a pedal inhibit signal activating a hydraulic cylinder to inhibit further depression of the brake foot pedal in response to detecting at least one of the wheels approaching a locked state. The electronic control will also generate brake pressure control signals activating an anti-lock brake actuator connected between the brake foot pedal and the input to the vacuum power booster of the brake system. The anti-lock brake actuator, in response to the brake pressure control signals, will maintain a maximum friction between the wheels of the vehicle and the road surface.

A best effort single channel anti-lock brake system for an automotive vehicle having a foot pedal, a master brake cylinder responsive to the depression of the foot pedal to provide pressurized brake fluid proportional to the pressure applied to said foot pedal and a brake actuator associated with each wheel of the vehicle, said anti-lock brake system comprising: at least one wheel speed sensor associated with at least one of the wheels of the vehicle, said at least one wheel speed sensor generating a wheel speed signal having a value indicative of the rotational speed of said at least one wheel; an electronic control having logic means for detecting when said at least one wheel is approaching a locked state to initiate an anti-lock mode of operation in response to said wheel speed signal, said electronic control further comprising means for generating a foot pedal inhibit signal and cyclic brake pressure control signals in response to said logic means being in said anti-lock mode of operation; means connected between the foot pedal and a stationary member of the vehicle for inhibiting further depression of the foot pedal in response to said foot pedal inhibit signal; and means independent of said means for inhibiting connected between the foot pedal and the master cylinder for cyclically controlling the brake fluid pressure applied to the brake actuators by the master cylinder in response to said cyclic brake pressure control signals, said cyclically controlled brake fluid pressure selected to maintain a maximum friction between the wheels of said vehicle and the road surface being engaged by said wheels.
