Rolling Resistance for a Vehicle when Driving Up and Down a Road Gradient
Paper in proceeding, 2026

Abstract: The rolling resistance of a vehicle is important, e.g., for range estimation. The question addressed is how total rolling resistance of a vehicle changes going up or down a hill, with everything else being the same. The basic idea in this paper is that rolling resistance of tires come from energy losses due to tire deformation repeated each wheel revolution. Going uphill requires more driving torque than driving on horizontal road, thus more deformation, more losses, and more rolling resistance. Going downhill is opposite, it requires less driving torque than horizontal road, and thus less deformation, less losses, and less rolling resistance. Based on model discussions, conjectures are made, and an experimental investigation method is proposed. Also based on model discussions, the first question is whether the rolling resistance decreases with per milles going uphill, if the inclination is in the order of percents, or if it increases with percents. An experimental program is suggested and initiated.
