The anti-lock brake system (ABS) is a safety feature for automobiles that regulates brake pressure and delivers predictable braking in the majority of circumstances by monitoring wheel lock-up. It necessitates the creation of a robust control system due to the unknown uncertainties on the braking system induced by altering the vehicle model dynamics and road conditions. To progressively decrease the automobile accidents caused by abrupt braking and will achieve the best brake performance. The mathematical model was developed considering vehicle speed, and slip ratio between the tire and the road conditions and simulation was done for Super Urban Vehicle of the ABS using Fuzzy logic controller and CarSim software in MATLAB/Simulink are the main objectives of this study. With the assistance of the fuzzy logic control approach and the MATLAB/Simulink software, a quarter-vehicle dynamic model was developed to simulate under a variety of road circumstances, such as wet and dry conditions, and at different speeds. Finally, it was determined that the braking distance was decreased and the vehicle stability was maintained during the simulation process by comparing the results of the simulation performed using the CarSim software connected to MATLAB/Simulink and the performance of the built controller.
