Makarov V. Scientific basis for improving the car's course steady motion.

Theoretical generalizations of scientific hypotheses and methods permitting to form the car's course steady motion while projecting automobile transport facilities and tyres as well as car's maintenance to solve an important practical task aimed at improving the car's safety have been suggested. Mathematical models for determining indices for the car's course steady motion as well as for analyzing mentioned indices to forecast the course steady motion for a running car have been given. Methods for diagnosing and forecasting the car's course steady motion have been suggested. Scientific significance has resulted in generalizing existed scientific hypotheses and creating modern conceptual principles, models and methods to determine parameters for the car's course steady motion considering variable elastic tyre rate. Main research results have been applied in manufacturing, educational process and scientific research. Key words: car, course steady motion, elastic wheel, variable tyre rate, motion equation, resistance coefficient.
