对下线检测线采集所得的数据采用数据分组处理的方法进行分析，然后基于Matlab／Simulink 运用状态空间模型框图对车辆模型进行仿真，通过侧向位移Y的响应曲线分析验证上述方法拟合得到的结果。在模型计算时先求侧向速度，再求侧向位移、跑偏量，能够较准确地揭示出驶入角对跑偏量的内在影响，同时较真实地反映汽车本身的动力学特征；仿真结果与上述结论一致，说明在行驶跑偏自动检测线环节所假设的车辆模型具有较高的仿真精度。

The data with noise collected from automatic vehicle inspection were analyzed by group method of date handling ( GMDH) method.And then the test vehicle was simulated via state-space model diagram Based on Matlab/Simulink, to verify the above fitting results by GMDH through response cure graph of the vehicle model's lateral displacement -Y.While calculat-ing, the lateral velocity was obtained firstly;then wandering test values indirectly, thus making for revealing the inherent relation-ship between them easier and embodying dynamic characteristics, compared to calculation wandering test values on the conven-tionally assumed shape of driving trace directly.The simulated result agrees well with above conclusions.It demonstrates that the proposed vehicle model can provide high simulation accuracy in noisy automatic vehicle inspection and the relevant solution pro-vides for a general thinking mind when dealing with the alike.
