摘要
本文将精细积分算法推广应用到考虑轮胎非线性的驾驶员-汽车-道路闭环系统的运动微分方程组的求解。推广后的算法原则上可用来求在计算机精度范围内的精确解。以转向盘角阶跃为例进行了非线性的仿真计算,对汽车的动态运动特性进行了分析。
In this paper, the finer integration method in time domain is extended to the response simulation of driver-vehicle-road closed-loop system taking account of tire nonlinearity. The extended algorithm can accurately solve the differential equation of driver-vehicle road closed-loop system within the computer precision. A practical example for step input of steering angle is simulated, and the vehicle dynamic performance is analyzed.
