Abstract
Brake pedal feedback is important for drivers to judge the braking time. Electric vehicles replace hydraulic brake pedal with electronic brake pedal simulator. Such a simulator transmits brake signal with cables. Therefore, a new electronic brake pedal simulator is designed in this paper, which can allow the implementation of an arbitrary nonlinear pedal force characteristic with electromagnet and different combinations of spring. The brake pedal feedback generated by the pedal simulator was emulated with matlab/Simulink. Furthermore, the springs were optimized to determine the combination to make the feedback meet requirements suitable for drivers. The simulated results prove the excellent brake pedal characteristic with the optimal groups of springs.
