| 摘 要： | 针对汽车操纵逆动力学研究现状,考虑轮胎侧向力的非线性,建立了非线性二自由度汽车模型,在方向盘角阶跃输入情况下,利用径向基函数网络建立了非线性汽车在不同摩擦因数路面上高速行驶时,汽车方向盘转角与横摆角速度之间的非线性映射关系.方向盘角阶跃输入的识别与仿真结果表明,利用径向基网络识别方向盘角输入的方法是可行的,并且具有识别精度高、运算速度快等优点.

| Abstract: | Based on a brief review of the developing history of vehicle handling inverse dynamics, completely considering the cornering force of tires, the nonlinear vehicle model of two-degree-freedom was established with steering angle input. Using radial basis function neural networks, the nonlinear mapping relation between lateral angular velocity and steering angle input was founded with different friction coefficient at high velocity. The identification results of step steering angle input showed that the model is not only feasible, but also have high accuracy, good stability and better computational speed. |
