Patent ID: 8474348

Claim:
An electrical-mechanical brake apparatus for simulating the feel of a purely mechanical brake system including; a bracket and a pedal arm movably supported by said bracket, a position sensor for detecting depression of said pedal arm, one of said bracket and said pedal arm presenting a cam body, the other of said bracket and said pedal arm presenting a cam follower, a cam bias interconnecting one of said cam body and said cam follower to one of said bracket and said pedal arm to bias said cam follower and said cam body against each other, one of said cam body and said cam follower being rotatable and said cam bias interconnects the rotatable one of said cam body and said cam follower to one of said bracket and said pedal arm, the cam body having a rest position portion, a first depression surface with a first radius of curvature, and a second depression surface with a second radius of curvature less than the first radius of curvature wherein the amount of force required for depression increases as said cam follower moves sequentially upwards from the rest position to the first depression surface to the second depression surface for simulating the feel of a purely mechanical brake system.
