Pedal assembly for electronic braking system
First Claim
1. 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.

Abstract
An electrical-mechanical brake apparatus includes a bracket (20) and a pedal arm (40) supported by the bracket (20). One of the bracket (20) and the pedal arm (40) presents a cam body (72). The other of the other of the pedal arm (40) and the bracket (20) presents a cam follower (64). One of the cam body (72) and the cam follower (64) is rotatable. A cam bias (86) interconnects the rotatable one of the cam body (72) and the cam follower (64) to one of the bracket (20) and the pedal arm (40). As the pedal arm (40) moves toward the bracket (20), the cam follower (64) moves along the cam body (72), compressing the cam bias (86) for simulating the feel of a purely mechanical brake system. In certain embodiments, the bracket (20) presents the cam body (72) while in other embodiments the pedal arm (40) presents the cam body. In certain embodiments, the cam body (72) rotates while in others the cam follower (64) rotates.
