Abstract: This article discusses some mechanical problems which occur by using hub-motors and individual wheel steering on road vehicles. Several multi-body dynamic simulations have been done in order to illustrate the high reaction forces in the steering actuator. This paper is not about an individual steering or control per se but aims to analyse the different forces in a given steering system for different steering scenarios.

Keywords: vehicle dynamics; simulation; hub motors; individual wheel steering; multibody dynamics; reaction forces; steering actuators; steering scenarios; vehicle control; X-by-wire cornering modules.
