| 摘 要： | 通过车辆七自由度模型和Uni-tire轮胎模型,对车辆质心侧偏角相图稳定区域边界进行研究,得到边界随车速及路面摩擦因数变化的关系. 建立了基于质心侧偏角相图稳定区域的车辆电子稳定性控制系统控制方法. 通过与基于理想横摆角速度的控制方法进行比较,文中确定的质心侧偏角稳定区域边界能够对车辆稳定性控制效果进行评价,也能够对车辆轨迹进行跟随.

| Abstract: | Based on seven freedom vehicle model and uni-tire model, the stable zone boundary of side-slip angle phasigram was acquired. The relation of boundary with vehicle velocity and road friction coefficient was obtained. The side-slip angle phasigram stable zone boundary was applied in electronic stability control (ESC) system. The simulation was carried out under veDYNA/Simulink environment. Compared with control logic based on ideal yaw rate, the stable zone boundary method could follow the ideal trajectory obviously better. The acquired stable zone could also provide a means of evaluation in vehicle stability research. |
