Active Roll Control Induced Tyre Wear in Electric Vehicles

Abstract

This study investigates the effects of active roll control on tyre wear in electric vehicles. The increased mass due to the installed batteries and the resulting higher vertical and lateral forces during dynamic manoeuvres contribute significantly to tyre wear in electric vehicles. In this study, advanced mathematical modelling is used to investigate these effects in a high-fidelity simulation environment. A series of open-loop and closed-loop tests were used to analyse the distribution of tyre forces and the resulting wear patterns. The results suggest that active roll control can significantly increase load-induced tyre wear, particularly on the outer wheel where the forces are most pronounced. This work provides insights into the challenges that engineers will have to solve when developing new platforms for electric vehicles.
