The fuel consumption of autobuses is significantly influenced by the different losses, such as air resistance, tyre rolling resistance of tire and other losses (bearing losses, losses in the drive, gearbox, etc.). The main goal of my current research is to work out indirect methods of measurement via experiments carried out with Mercedes-Benz REFORM 501 autobus to define rolling resistance, one of the most decisive losses. During the evaluating of measurements, I used a special method because the power values were determined based on the power characteristic curve of OM 936/260 kW engine of the bus. During my calculations, I considered the losses due to rolling resistance and air resistance and other losses due to the use of additional auxiliaries furthermore, the losses in the drive elements of the vehicle (3% of the used engine power) were considered as constant. Later on, the defined values will serve as input data for modelling the vehicle energetics calculations.
