Abstract
The results of the analysis of changes in the controllability of vehicles when driving on ultra-low pressure tires on public roads are presented. The presence of a significant influence on the reaction of a wheeled vehicle of the frequency of the control action has been proved. Such an in-dicator of the change in controllability as the delay in the angular velocity of rotation of the wheeled vehicle from the control action is proposed. The results of mathematical modeling of the effect of the parameters of ultra-low pressure wheels on the directional controllability of all-terrain vehicles are obtained. The data provided made it possible to identify the safest tire stiffness parameters (and hence the amount of air pressure) the vehicle, affecting its active safety, as well as determine the limits of their permissible modification. It has been established that in the entire range of changes in the parameters of ultra-low pressure tires, the speed of all-terrain vehicles on public roads should not exceed 50 km/h.
