The article presents results of comprehensive theoretical and experimental studies aimed at creation of traction-and-transport vehicles (TTVs) - trucks and tractors of the future, which meet the modern requirements for their active and environmental safety. The concept is based on the original complex mathematical model (CMM), which allows simulating various interaction schemes of all TTV systems, including those accounting for the contact (tribological) interaction of the wheel with the rolling surface. The CMM was used to study the work of all the subsystems of TTVs equipped with electric transmission, all-wheel steering and electro-hydraulic servo system of wheel turning, as well as with the wheel-springing system and the onboard information-and-control system. Besides, the CMM and its individual units were used as simulators for programming the functionality algorithms of all these subsystems and their relationships with each other.

The article enumerates the main problems encountered in creating main traction-transport vehicle (TTV) units as mechatronic systems. The authors review the results of theoretical and experimental studies of creating TTVs - automobiles of the future based on mechatronic systems. The analysis of the results shows that TTV progress is only possible based on a broad introduction of mechatronic modules into vehicle designs. This significantly increases the role of electronics and control systems. The paper shows that TTVs with mechatronic systems cannot be unambiguously described mathematically based on the existing theory of applied mechanics. A theory describing the laws governing the functioning both of individual TTV systems with their interrelationships and of the object as a whole should be developed.

The aim of this paper is to present the main principles of building the traction electric drive (TED) of the wheels of a heavy-duty road commercial vehicle.A high importance is given to the complex nature of designing and summing up the practical experience of making particular designs of the traction electric drive; as well as to the involved terms and definitions. The design of the AC TED with asynchronous motors and an AC generator looks most promising and having the best price/quality ratio.

In the coming half-century, the global transport industry is expected to be affected by two technological revolutions - the first will start upon admission of autonomous vehicles to public roads, while the second will finalize a complete removal of manned vehicles away from them. As a result of the above revolutionary shocks, several major changes are anticipated: the modification of whole paradigm of ground vehicles; introduction of new business models in the transport sector, as well as new vehicle ownership forms; transition to technologies of collective and cooperative management and synchronized parrying the dangerous traffic collisions.
