Abstract
A vehicle brake system. The system includes a wheel brake, a brake pedal, a master cylinder, a first valve, a second valve, a pump, a pressure sensor, a pressure controlling device, and a controller. The master cylinder increases a pressure of a brake fluid in the brake system based on a user depressing the brake pedal. The pump pumps 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. The pressure sensor senses a pressure of the brake fluid in the brake system. The pressure controlling device reduces a pressure of the brake fluid at the master cylinder. The controller operates the first and second valves, the pump, and the pressure controlling device during a controlled braking event.
