Abstract: Taking the single wheel vehicle model as the research object, the mathematical model of the auto-mobile ABS system is established under the Simulink environment. The overall model of the ABS system is established by using the logic control strategy with the slip ratio as the main reference value. The simulation results are compared with those without ABS. The results show that the ABS system can significantly im-prove the braking performance of the vehicle and thus improve the safety factor of the vehicle during braking.
