摘要
详细研究了驾驶员 汽车闭环系统直线行驶稳定性问题。在线性范围内分析了驾驶员预瞄时间和轮胎刚度对临界车速的影响 ;在非线性领域内运用Hopf定理等非线性理论研究了当系统失去直线行驶稳定性后的特殊运动形式 ,并以某一国产汽车为例 ,验证了该车失去直线行驶稳定性后 ,将出现稳定的蛇行运动。
The straight driving stability of driver vehicle closed loop system is studied The effects of driver's foresee time and the stiffness of tire to critical velocity are analyzed in linear domain Using Hopf theorem,the traits of vehicle's motion are studied when the stability is lost in nonlinear domain Taking a domestic vehicle as an example,the results are validated that the vehicle will have a stable snaking motion when the straight driving stability is lost
