Abstract:
1. A vehicle brake system, the system comprising: a wheel brake; a brake pedal; a master cylinder coupled to the brake pedal and configured to increase a pressure of a brake fluid in the brake system based on a user depressing the brake pedal; a first valve having an open position in which the brake fluid flows through the valve and a closed position where the brake fluid is prevented from flowing through the valve; a second valve having an open position in which the brake fluid flows through the valve and a closed position where the brake fluid is prevented from flowing through the valve; a pump configured to pump the brake fluid through the first valve to the wheel brake and to draw the brake fluid from the wheel brake through the second valve; a pressure sensor configured to sense a pressure of the brake fluid in the brake system; a volume manipulation device configured to cause a change in a capacity of the vehicle brake system; and a controller configured to receive an indication of the pressure of the brake fluid from the pressure sensor, to operate the first and second valves, the pump, and the volume manipulation device during a controlled braking event.
