In this paper,the ABS dynamics model based on slip rate control was first built in MATLAB2023b/Simulink environment,and the vehicle braking process was simulated by fuzzy PID control and classical PID control.By comparing the vehicle speed and wheel speed curve,slip rate curve,braking deceleration curve and braking distance curve on dry road and wet road,the improvement of vehicle braking effect by fuzzy PID control is analyzed.The experiment results show that the braking distance of fuzzy PID control on dry road is reduced by 0.642m,and that on wet road is reduced by 1.55m.The braking distance of the fuzzy PID control on the disturbed dry road is reduced by 1.562m,and that on the disturbed wet road is reduced by 1.6m,which further proves the effectiveness of the fuzzy PID control.
