Dependence of braking vehicle characteristics on environmental conditions

Abstract

The main purpose of the work is to confirm influence of operating conditions at low temperatures on change in braking characteristics of cars. The factors influencing the result of braking are determined, cars from the general set of all vehicles operated in Ulan-Ude are selected, taking into account certain conditions. A test method is proposed that makes it possible to obtain functional dependences of the specific braking force on ambient temperature during storage of the vehicle, and also the functional dependences of the specific braking force on storage temperature under operating conditions in Ulan-Ude are obtained. The insignificant influence of air humidity on results of the braking process in conditions of Ulan-Ude was revealed. The correlation of the value of specific braking force from the ambient temperature was estimated, the statistical indices obtained indicate a high correlation between the compared values. The tasks of further studies that need to be performed to determine most complete picture of the influence of ambient temperature and air humidity on parameters of the functioning of brake system a vehicle were determined.

Extreme environmental temperatures and motorcycle crashes: a time-series analysis

“…Vehicle performance could be influenced by weather characteristics. Brake pads' performance could be affected by high temperatures due to brake fade and by cold temperatures because of the increase in the risk of brake sticking (Krasnoshtanov et al 2018). Moreover, temperatures could influence human behavior and cognitive performance (Taylor et al 2016).…”
