Mathematical model of an electric car to diagnose its traction qualities on a chassis dynamometer

The paper outlines the developed mathematical model of an electric vehicle to control its traction and dynamic qualities on a chassis dynamometer. The purpose of the work is to expand the capabilities of diagnostics and analytical determination of electric vehicle dynamics parameters. The developed mathematical model includes descriptions of the following processes: the operation of the electric motor, torsional vibrations in the transmission of an electric car and the chassis dynamometer, the processes of tires interaction with the circular-shaped surfaces of the chassis dynamometer
