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.

An electro-hydraulic servo system makes the basis for a mechatronic locomotion module (LM) and for a complex comprising an LM and an undercarriage of a vehicle. The servo system of the wheel module/LM complex is a combination of the information and power channels of the electro-hydraulic wheel drive within the steering system. A combination of the servo systems makes up a complex of servo systems of the steering system of the multi axis wheel mover of the vehicle. Theoretical and experimental studies of the functioning all-wheel steering were aimed on substantiation the rational algorithmic maintenance of the automatic control system. The results of the study allowed formulating the basic principles of designing and calculating the functionality algorithms for the steering system of the complex of mechatronic modules of the multi-axis vehicle.
