摘要

Improving the stability and safety is of great significance for thein-wheel electric vehicle. There are many studies only concentrating on activefront steering (AFS) control or direct yaw-moment control (DYC). However,When the in-wheel electric vehicle is under extreme conditions, AFS or DYCalone is not effective. In this paper, an integrated controller of AFS and DYCis proposed. Firstly, the ideal values of yaw rate and sideslip angle can be cal-culated based on the two-degree-of-freedom vehicle model. Secondly, the AFScontroller is obtained according to the backstepping-based fast terminal slidingmode (FTSM). Then, the DYC controller which consists of the upper controllerand the lower controller is constructed. The upper controller is developed viathe integral-based second-order sliding mode (SOSM). The appropriate torqueis outputted to each wheel by the lower controller. Finally, the simulation re-sults show that the actual yaw rate and sideslip angle can approach the idealones as closely as possible under the proposed integrated controller.
