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.
