It is developed a mathematical model of the braking system of a car equipped with ABS by means of MATLAB SIMULINK. The results, which allow visually explore the basic physical processes associated with the exploration and development of existing and new control algorithms of ABS, are received. The article deals with a pneumatic braking system under the control of ABS, which is most common and installed on buses and trucks. Its modeling is performed on a graphical interface of MATLAB SIMULINK, and is essentially a means of visual programming. This work allows us to estimate the correct approach to the study of the dynamic and technical parameters of the ABS and achieve clarity of the processes occurring during operation of the ABS. The study found that this model in the first approximation can be used as the primary outcome correct approach to mathematical modeling of the ABS. The obtained results are important for the further improvement of the primary model, namely, accounting for additional factors that affect the correct operation of the brakes of the car (road condition, accuracy of the sensors, dynamics of the car traffic, wheel drift during turn, etc.).
