Development of a measurement method to determine rolling resistance

Abstract

Nowadays, car manufacturers tend to produce cars of low consumption to comply with stricter and stricter environmental protection standards. Fuel consumption can only be reduced by decreasing losses emerging during vehicle operation. This is corroborated by the fact that due to the terminal capacity of batteries of electric cars, manufacturers aim to reduce losses to enhance their range of operation. The main goal of our current research is to work out indirect methods of measurement to define rolling resistance, one of the most decisive losses. Later on, the values defined will serve as input data to model vehicle energetics calculations. During our experiments, measurements were carried out with both summer and winter tires. During the evaluation losses of the engine, rolling resistance and air resistance were all considered, while losses from the driving components of the vehicle were ignored.
