Abstract：[Objective]To solve the problem of no direct mechanical or hydraulic connection between the brake actuator and the brake pedal in an electronic mechanical braking system,leading to no feedback of road feel,a brake pedal feeling simulator was proposed based on magnetorheological dampers.[Methods]Ansys/Maxwell and Matlab/Simulink were used as the platform.The structural design of the sinking brake pedal feeling simulator,the structural design of magnetorheological damper,magnetic circuit analysis and electromagnetic simulation were carried out respectively,and the simulation analysis of traditional proportional-integral-derivative(PID)and fuzzy adaptive PID control under different working conditions of the whole system was compared.[Results]The simulation results show that the brake pedal feeling simulator can track the characteristic curve of the traditional pedal well under different working conditions and has wide applicability.Compared with the traditional PID control effect,the fuzzy adaptive PID control has higher control precision and smaller control error,and has good application prospects.
