The invention provides a distributed driving electric vehicle stability control system and method based on a phase plane, and the method comprises the steps: inputting real-time parameters of a vehicle into a stability judgment unit, building a two-degree-of-freedom vehicle analysis model in the stability judgment unit, drawing a side slip angle-yaw velocity phase plane graph under all working conditions, and calculating the stability of the vehicle; a curve type stability domain and rhombus stability domain boundary parameter database is established, the number n of intersection points of a ray extending in any direction with a vehicle driving state point as a starting point, the stability domain boundary and a phase plane graph frame serves as a criterion, and the accuracy of vehicle stability judgment is effectively improved.

    本发明提供了基于相平面的分布式驱动电动汽车稳定性控制系统及方法,将车辆实时参数输入稳定性判断单元,在稳定性判断单元中建立二自由度车辆分析模型,绘制全工况下质心侧偏角‑横摆角速度相平面图,建立曲线型稳定域和菱形稳定域边界参数数据库,以车辆行驶状态点为起点沿任意方向延伸的射线与稳定域边界和相平面图边框的交点个数n作为判据,有效提高了车辆稳定性判断的准确度。
