Abstract
A vehicle braking system includes a brake pedal, a master cylinder, and an electronically-controlled booster having an input member and an output member adapted to provide an input force to the master cylinder that combines a driver-supplied input force and a boost force provided by the electronically-controlled booster. A wheel cylinder is fluidly coupled to an outlet of the master cylinder and operable to provide a wheel braking force proportional to the input force to the master cylinder. A pump is operable to pump fluid toward the wheel cylinder to provide an assisting wheel braking force. A controller is programmed to trigger a hydraulic braking assist routine in which the pump is activated to provide the assisting wheel braking force. The controller is programmed to reduce the boost force provided by the electronically-controlled booster during the hydraulic braking assist routine.
