Efect of Tire Model on Operation of Antilock Brake System of Vehicle

Tire of vehicle as the single contact point of vehicle to ground and also the common component of brake, suspension, steering and transmission systems play a great role in safety of passengers, stability and vehicle control. The goal of this research is to study and analyze effect of tire different models on designing controller of antilock brake system and ultimately whole operation of vehicle. In this research first of all, tire different models were introduced and vehicle and brake system was modeled. Then a fuzzy logic controller of ABS was designed and finally this modeling and designing were simulated in Matlab/simulink software. Result of the research shows that in each tire model according to slip of tire, the estimated friction value by tire model, effects on stopping time, stopping distance and decrease of wheels speed.
