Abstract

This paper proposes a system to enhance rollover propensity for micro-scale electric vehicle by using Direct Yaw-moment Control (DYC). The system is composed of a feedforward yaw-moment controller and a longitudinal force distribution controller. The yaw-moment controller is a desired roll angle following controller. And the yaw-moment control input is calculated from the feedforward control law with respect to front steering angle based on 3-DOF linear vehicle model. Consequently, the vehicle is controlled by DYC with driving force distribution of the in-wheel motors. Finally, the effectiveness of the proposed control system to enhance rollover resistance is verified by simulation and experimental study by using micro-scale electric vehicle under condition of dynamic steering input.
