Abstract
A brake pedal assembly for a vehicle equipped with an electronic or “brake-by-wire” braking system includes a brake pedal feel emulator which mimics or emulates the pedal feel of a conventional hydraulic braking system. The brake pedal feel emulator includes a single cantilever spring which reacts against a shaped surface and is mounted such that the free end thereof applies a force to the brake pedal which varies as the point at which the spring diverges from the shaped surface changes in response to movement of the brake pedal. The free length of the spring is therefor varied as the pedal is depressed as a function of the shape of the shaped surface, so the force applied to the pedal may be designed to vary to emulate the feel of a conventional braking system.
