The paper presents testing results that serve the development of research methodology for steerability and stability of military special-purpose vehicles using the SR 60th control robot. Due to their high centre of mass and a large moment of inertia of their body, armoured vehicles pose a serious hazard during dynamic maneuvers. The phenomenon of oversteering is dangerous, which causes automatic reduction in turning radius and thus increases the lateral acceleration at the high-lying centre of mass usually leads to the vehicle rollover. In conditions of a limited tractive adhesion, any slight side impulse (side wind, a drive through a road rut) is enough to result in the vehicle sideslip. At high inertia, each response of any surprised driver is delayed. Therefore, the research studies on behaviour of special-purpose vehicles, including the military ones during road tests are particularly dangerous. The developed methodology allows mitigating the risk of using the steering robot and enables to obtain a very high research results repeatability, unattainable even for a very skilled test driver. The procedure developed hereto is used to accurately determine the safe driving velocity while making sudden maneuvers, and for vehicles steerability characteristics. It may become an excellent tool to verify simulation models.
