【 摘 要 】

The research topic relevance is determined by the global significance level of traffic safety improvement. The purpose of the work is to create mathematical model and software for the active vehicle safety experimental intelligent system. To solve this problem, methods of indirect vehicle state variables measurements were used. As a mathematical model, we used a system of equations for the wheels rotation speed on a bend. For estimating the parameters of the mass center and the wheels motion, standard wheel speed sensors and algorithms for processing the measurement data are used. The task of angular drift velocity determining based on wheels rotation frequency measurements is ill-posed and additional conditions are introduced to solve it. To predict the wheel drift and car rollover, extrapolate algorithms are used. These phenomena are prevented by the certain brake formation that limit the object speed at the predicted boundaries level. The research novelty is to create algorithms for an experimental system that provides the solution to the wheel drift and rollover prevention problem in a minimal configuration of technical means.
