Abstract In the vehicles development also developed a variety of control systems. However, in their development it is necessary to have a mathematical model of the control object, that is, the vehicle model for the study of electronic control systems. Mathematical modeling is the most effective and promising method of studying the control object behavior. It is possible to carry out vehicle mathematical modeling and its components with sufficient high accuracy and compliance with its real prototype. But there are cases that it is not possible to simulate in detail some phenomena of the control object. In order to verify the accuracy of the compiled model, model verification of the developed vehicle is carried out. The basis used the KIA Sorento. It has AWD based on front wheel drive. This vehicle, equipped with measuring and recording devices, which carried out on the roads of the testing ground (FSUE “NAMI”). The work focuses on modelling the simulation of transmission units in the vehicle. The systems of equations of the engine, gearbox, transfer case, main gears and elastic drive shafts are written. Races on curvilinear trajectories were carried out. It also presents results comparison of the real vehicle movement and the results carried out from modeling in MATLAB&Simulink. The accuracy of the developed mathematical model and admissibility in further application in the development of control systems are proved.
