摘要
根据ABS制动试验台的测量记录的制动管路压力变化数据,对Jetta-GTX轿车制动管路的压力增减变化特性进行了建模,通过对模型曲线和试验曲线的对比表明,利用最小二乘曲线拟合法直接识别得到模型的参数,从而可以较好地拟合ABS系统制动轮缸的压力变化。
With the help of the recorded data in brake line measured pressure of ABS test bench, it builds the brake line pressure changing model. During the model forming process, it uses the least squares method to identify parameters of mathematical model. The results show that the identified parameters can fit the experimental pressure changing line quite well.
