Adjustable brake pedal system

摘要

A brake pedal assembly for a brake-by-wire system or vehicle having a traction battery. The brake pedal assembly has both a pedal feel simulator and an adjustable brake pedal. The pedal feel simulator has a fixed cam surface and a moving cam follower that provides increased resistance that simulates that of an actual brake system as the brake pedal arm is depressed. The brake pedal assembly has a pivotal adjustment subassembly that the cam follower may extend from. The adjustment subassembly may also have a brake pedal arm adjustably connected to and extending therefrom. The adjustment subassembly provides a consistent path of rotation per brake pedal depress allowing for the cam follower to have substantially consistent movement across the fixed cam surface, providing substantially consistent pedal feel feedback, regardless of where the brake pedal has been adjusted to within a vehicle foot-well.
