Automatic control of air pressure in tires as a factor of safety improvement of wheeled vehicle operation in agricultural sector

The article is devoted to the problem of automatic modes of tire pressure regulation in transport vehicles used generally in agriculture where there are a lot of roads performing in very bad condition with mud. Almost all kind of wheeled vehicles could be fitted with air pressure regulation systems. Limits of tire pressure usually regulated by manufacturer so any kind of engineering modifications of tire systems should work in that limits strictly bordered by manufacturer of vehicle and tires. The presented article contains engineering based and practical orientated way to improve drive safety and operator working conditions. Each type of road has such characteristics as safety speed, angle of rollover etc. The authors propose mathematical model of regulation process on the basis of the above mentioned factors of road and vehicle functioning. In the process of modern construction of vehicles the way of module upgrades of existing vehicles becomes more and more popular. In this regard the authors try to propose one of the compromise universal solution for the problem of automatic tire pressure control and regulation. (paper)
