说明：  通过状态空间方法建立了线性二自由度的车辆模型，然后通过转换，将状态空间转换成传递函数的形式，能看到速度变化后，质心侧偏角和横摆角速度的变化趋势。(The vehicle model with linear two degrees of freedom is established by the state space method, and then the state space is transformed into the form of transfer function through transformation. After the speed changes, the change trend of the sideslip angle and the yaw rate of the center of mass can be seen.)

说明：  自动随机优化超声波感器位置，达到信号测量最优(Optimal sensor location)

用于进行声压转换的matlab文件，声压数据来源于ansys软件的计算后导出来的。(Used for sound pressure to convert matlab file, sound pressure data from the calculation software ansys guide out.)
