BACKGROUND: The development of aerospace machinery leads to the need for transportation of increasingly large-sized indivisible cargo by ground vehicles. At the same time, taking into account the peculiarities of the transported cargo, a number of special requirements including maneuverability are imposed on vehicles.

AIMS: Defining the magnitude of the semitrailer path offset relative to the truck path.

METHODS: The solution of the system of ordinary differential equations is performed using the MATLAB/Simulink software implementing the Runge-Kutta-Felberg method of the fourth-fifth orders.

RESULTS: The comparative graph of the values of the normal and ideal jack-knifing angles has been obtained.

CONCLUSIONS: The developed mathematical models and calculation software make it possible to assess the maneuverability of newly developed prototypes quite quickly and accurately.
