Abstract
A vehicle braking system includes a brake pedal, a master cylinder, a braking circuit with a wheel cylinder, a brake pressure generator for brake-by-wire braking, and a pedal feel simulator. In response to detecting impending wheel lock-up, a controller conducts an anti-lock braking routine during which the controller is programmed to create an artificial haptic feedback pulse to the brake pedal by opening a normally-open isolation valve between the master cylinder and the brake circuit to move a master cylinder piston until a compensation port opens.
