Abstract: This paper describes a methodical aspect for tyre rolling resistance force measuring and calculating during driving at constant speed, which has been developed at the Institute of Automobiles in Kragujevac in cooperation with faculty of Mechanical Engineering, Kragujevac. The main goal of this paper is to observe the influence of tyre pressure on a vehicle|s dissipative energy, that is, fuel consumption. Besides the influence on fuel economy, tyre pressure is also of significant importance for vehicle stability during cornering and braking, hence tyre pressure might be considered as a multiple risk factor. To measure the vehicle|s speed, the DATRON measuring system has been used, while for data acquisition and calculation of rolling resistance force and corresponding power a portable computer and software developed in the Institute of Automobiles was used. Fuel consumption was measured through a series of tests, performed at several different tyre pressures.

Keywords: ADVISOR; advanced vehicle simulator; fuel consumption; rolling resistance; energy saving; vehicle tyres; fuel consumption; simulation; resistance force measurement; tyre pressure; dissipative energy; fuel economy; vehicle systems modelling.
