Currently, developers of multi-wheeled vehicles (MWV) show growing interest in an electro-mechanical drive in the «motor-axis»implementation. However, in designing such types of traction electric drive (TED) the problems arise, mainly, from a lack of creating experience and of ready algorithmic solutions to control the traction motors. Methods for implementing the individual TED cannot be used because of the cross-axle differential available in the leading axle drive, which does not enable the input torque control of each wheel singly. The paper offers a law to control a traction electric drive of MWV leading axles that includes the law to control the traction and braking torques on the leading axles as well as algorithms of anti-lock brake and traction control systems.Simulation methods of mathematical modeling have proven efficiency and effectiveness of the proposed control law, when performing MWV maneuvers. Research results can be useful for companies in automotive industry, which, first of all, deal with design and manufacturing of special multi-wheeled vehicles of various classes and purposes, as well as for institutions, which develop control systems for wheeled transport equipment.
