Kashkanov V. Perfection of method determination of traction factor for investigation mechanisms of road and traffic accidents

A research object is a process of the urgent braking of car without blocking of wheels. The article of research is a error determination lowering of traction factor during conducting of motor-vehicle examination. Researches methods of collection, choice and analysis of information were used, theory of unclear plurals, integral calculation, and mathematical design. Scientific novelty of the got results. First quantitative and high-quality character of influencing of type and state of travelling coverage, type and state of tires, loading, is complex taken into account on a wheel and rates of car movement, equipped ABS, on the use of couplings qualities of its wheels with a supporting surface at the urgent braking. Practical importance of the got results: the offered method enables to determine, more exactly than present methods, coefficient of rolling friction wheels of car, equipped the ABS, with travelling coverage on the basis information of protocol of road and traffic accidents, without the use of the special equipment or conducting of travelling tests. They can be used in the future methods of examination of road and traffic accidents with participation of cars, equipped ABS. Performances of this thesis got introduction in the research expert-criminality's center of MVS of Ukraine in the area of Vinnytsya. Sphere of the use: in the research expert-criminality's departments during investigation mechanisms of road and traffic accidents; in research organizations what are engaged in the study of couplings qualities of wheels with a supporting surface in the process of braking of cars.
