驾驶员对汽车行驶方向稳定性影响的分析方法

在驾驶员一汽车闭环系统操纵动力学模型基础上，将驾驶员参数变化范围用区间数表示，用直接优化法对非对称区间矩阵特征值问题进行求解，从系统与控制理论角度定量地揭示了驾驶员对汽车行驶方向稳定性的影响。分析结果表明，汽车行驶方向稳定性的区间分析方法可以应用于使车适合于人的汽车操纵动力学设计。

Analysis Method of Driver Effects on Vehicle Directional Stability

A new vehicle directional stability analysis method was presented based on the research of driver qualification effects on vehicle directional stability by using the eigenvalue problems of unsymmetrical interval matrices. Driver qualification effects on vehicle directional stability were simulated by using interval value. Based on the vehicle handling dynamics model of drive-vehicle closed-loop system considering driver qualification with steering angle input, the paper quantitatively revealed driver qualification effects on directional stability from the point of system and control theory of view. A direct optimization method was presented for solving eigenvalue problem of unsymmetrical interval matrices. The directional stability analysis results show that the present method can direct the design of vehicle in order that it is more suitable to men.
