Abstract：To improve the braking comfort, the brake pedal feel was simulated by pedal stroke simulator with the consideration of brake pedal feel as core part of brake-by-wire system and direct-relationship to driving comfort and safe travel performance of vehicle. The brake-by-wire system with pedal stroke simulator was analyzed and compared with the traditional braking system. The pedal stroke simulator model was established by AMESim software, and a single neuron adaptive intelligent PID control strategy of pedal stroke simulator was designed by MATLAB/Simulink software. The basic parameters of bench test of traditional vehicle braking system was set to be simulated for validation. The simulation results show that the pedal stroke simulator and the control strategy can meet the performance requirements of traditional braking system with improved braking comfort.
