搭建汽车操纵稳定性和平顺性仿真中常用的魔术轮胎和dugoff轮胎，整理到一个simulink文件中，两种轮胎的模型均已和carsim中的仿真结果进行对比和验证，精度较高。(The magic tire and Dugoff tire commonly used in vehicle handling stability and ride comfort simulation are built and sorted into a Simulink file. The two tire models have been compared and validated with the simulation results in Carsim, and the accuracy is high.)

用于复杂背景下的背景提取，比如高速公路等等，效果非常好(background extract background extract)
