US Patent 9616861 Pedal assembly for electronic braking system

An electrical-mechanical brake apparatus includes a bracket and a pedal arm supported by the bracket. The bracket has a cam surface. An arm extends from the pivot arm to a follower. As the pedal arm moves toward the bracket, the follower moves along the cam surface, compressing the cam bias for simulating the feel of a purely mechanical brake system. In certain embodiments, the earn body rotates while in others the cam follower rotates.
