    摘要: Various brake control systems and methods are provided herein. In one implementation, a brake pressure control system having a shutoff valve (24) in a hydraulic conduit (26, 30) between a pressure origination source (16, 18) and a wheel brake (20), the shutoff valve selectively isolates the pressure origination source from the brake responsive to an indication that a wheel associated with the brake meets a skid condition, and an actuator assembly (28) comprising an actuator (34) that regulates fluid brake pressure after the shutoff valve isolates the pressure origination source from the brake. The actuator assembly operates independently of the shutoff valve and is coupled to the hydraulic conduit between the shutoff valve and the brake. The actuator assembly also effects displacement of the actuator for increasing and decreasing brake pressure. A controller (44) determines if the skid condition has been reached and controls the shutoff valve and the actuator assembly based upon the skid condition.
