汽车防抱制动过程仿真计算模型及其参数的系统辨识

Identification of Automotive Anti-lock Braking System

本文根据系统辨识理论和防抱制动装置工作原理,建立汽车制动ARMA模型和防抱制动装置仿真计算模型,并根据防抱制动试验中获得的数据对所建模型的参数进行辨识。最后的仿真计算结果与试验值吻合良好,表明系统辨识方法是分析汽车防抱制动过程的有效手段。

In this paper, an ARMA-model for Vehicle braking and a simulation model of ABS were set up, based on the theory of system identification and the working principle of ABS. And the parameters of the models were identified from the results of the anti-lock braking test. The simulation results with the models were well supported by experimental ones. It is indicated that system identification is an effective method for analysing the anti-lock braking process.
