Abstract
A brake-by-wire automotive braking system includes a master cylinder connected to a number of wheel cylinders, with the master cylinder being actuated by a brake pedal assembly operatively connected with a master cylinder force simulator simulating the resistive force/displacement characteristics of the master cylinder itself. An electronically controlled compliance device selectively immobilizes the master cylinder force simulator so that the resistive force provided by the simulator may be applied selectively to the brake pedal. This produces a transparency in the brake pedal's operational feel, notwithstanding the presence or absence of force provided by the master cylinder force simulator.
