Abstract
This paper is about a project of a heavy multipurpose all-wheel drive vehicle. To ensure highest road safety and mobility requirements mathematical analysis and simulation is the one of the most important thing. The vehicle’s transmission enables dependent on road conditions torque distribution through axes and wheels. The system of torque distribution uses individual motors for every wheel getting power from both the dieselelectric unit and batteries or separately according to control program. The vehicle uses a 4- axis chassis which provides the highest level of the off-road ability. Mathematical model enables calculating and simulation of vehicle systems and units in all needed modes of motion. The article examines model structure and principles of operation. The work is highly important. Mathematical analysis reduces time and financial expenditures for vehicle development and testing.
