The main trend in designs of modern automobiles is a widespread use of mechatronic modules and systems. These modules are built as a symbiosis of electric, electronic and hydraulic components, united by means of the control system and intended to fulfill particular targeted functions. In the article results of a comprehensive theoretical and experimental study aimed at creating a drive and a control system of a wheel module intended to be used with the steering and spring systems of an automobile and a mobile robot have been considered. Also the basic principles of the a complex of mechatronic drives of the wheel module (CMD WM) and technical requirements for the components of the complex as a mechatronic module of the system of active safety of the automobile and mobile robot have been formulated.

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.

The modular designing principle is generally recognized in the automotive industry. However, the issue of building a wheel open-link locomotion module (OLLM) as a combination of steering (wheel turning), springing, traction drive and braking systems is not properly developed yet. An automated control system (ACS) is needed to able to unite and coordinate all the vehicle systems intended to manage the wheel. The automated control system intended to manage the steering and wheel springing parameters is a combination of an information and power channels, through which the wheel is electro-hydraulically driven, and the steering, springing and braking systems are controlled. The number of such channels in a wheeled mover of the vehicle or mobile robot is defined by the wheel type (driving, driven, steered or non-steered wheel). The plurality of such channels forms a complex of automated control systems of the wheeled mover.
