Effective delivery of indivisible bulky and heavy loads whose weight can reach hundreds tons is of particular importance for development of various sectors of economy and support of defense capability. Special road trains provide open road transportation and off-road haulage of this kind of goods, but in difficult traffic environment their using capabilities are significantly restricted by a lack of the road-ability. For a road train to reach the better road-ability is possible by increasing the number of drive wheels. This can be achieved through the use of an activetrailer as its part. The effectiveness of using this drive may be estimated through comparison of the road train road-ability with the turned on and turned off passive and active semitrailer in different road environment. A mathematical model of the dynamics of the two-link semitrailer truck was created to solve the problem of comparing dynamic characteristics of the road trains with the passive and active semitrailer. The developed mathematical model of the four-axle tractor and three-axle semitrailer was implemented in the MATLAB® Simulink. It was revealed that in some traffic environments it is advisable to disable the semitrailer drive. A drive control algorithm of semitrailer wheels based on the analysis of the forces in the coupling device was proposed. Data from the sensors installed in the pin of the coupling device serve as a primary source of information for the control system. Test runs enabled us to define control limits for the drive control system. The article considers three cases to use the power of traction motors of the semitrailer in a predetermined range. A number of numerical experiments have been conducted to define dynamic qualities of the road trains in different cases of using semitrailer power. The analysis of results allowed us to draw conclusion that using a system of the semitrailer drive to be connected enables increasing efficiency of the road train when moving in difficult road environment
