Abstract

It is known that tyre characteristics are changed by the tyre temperature. This paper shows that the tyre temperature influences the tyre cornering characteristics such as tyre cornering stiffness and RRC and so on, and confirms this finding by calculating how the tyre temperature changes vehicle characteristics. In addition, the tyre temperature was measured on public roads and the vehicle characteristics in general driving conditions were estimated.

KEYWORDS – tyre temperature, tyre cornering force, rolling resistance coefficient, vehicle dynamics, objective evaluation
