Dynamics Modeling and Characteristics Analysis of Distributed Drive Electric Vehicles

Abstract

Due to the short transmission chain, compact structure, and the feature of quick and accurate torque generation, distributed drive electric vehicle (DDEV) has attracted many researchers from academia and industry. The significantly redundant execution characteristic of four independently driven in-wheel motors also provides more potential to guarantee the vehicle dynamics performance. Moreover, the unique torque vector control of DDEV generates the direct yaw moment control mode. It has been proven to be effective to modify the vehicle steering characteristics. Through a reasonable torque vector allocation strategy, the energy-saving can also be realized. This chapter will introduce the distributed drive electric vehicle from the viewpoint of the dynamics modeling, stability performance analysis, and energy-saving strategy.
