Technical Examples

A braking system including a pre-charge with a plurality of pumps disposed in parallel with respect to one another. The pumps can direct pressurized brake fluid to the brakes during a controlled braking maneuver. The pumps operate with offset operating cycles such that a first pump is drawing fluid while a second pump is pushing fluid to the brakes. The invention provides an embodiment having three pumps operated in parallel, wherein the pumps define operating cycles offset 120 degrees from one another. The invention also provides a separate master cylinder reservoir feed circuit to improve response of the system, especially cold weather response.
