Abstract
An electronically controlled vehicular hydraulic brake system provides anti-lock braking, traction control, and/or vehicle stability control. The system includes a hydraulic control unit (HCU) containing pumps, valves, and other components in fluid communication with wheel brakes. Performance of the braking system can be improved by systems and methods according to this invention. A preferred system for improving braking performance according to the present invention includes a passive precharge system having a precharge manifold.
