Abstract

In-wheel motor driven vehicles are powered directly by in-wheel motors installed inside the wheel which provide independent control of the driving and electrical braking torque. This paper presents a torque vectoring control system (TVCS) to improve the coupling and complex matching of the in-wheel motors. This system is independent of other systems in the vehicle and, thus, is a power assembly for electric vehicles. The paper describes the TVCS network topology and the software and hardware architecture of the torque vectoring controller. An in-wheel motor driven vehicle was built equipped with TVCS with the single-lane change test showing that the TVCS can effectively lower communication load rates and facilitate integration of the in-wheel motors. The test vehicle provides the basic system functions in a test platform for development and optimization of the torque vectoring control algorithm.
