Performance Evaluation of Anti-lock Braking System Based on Information Entropy

车辆行驶环境复杂,防抱死制动系统工况多变,其制动性能易受多种不确定因素影响.对防抱死制动系统的性能评估可以衡量控制策略的有效性,也可以为反馈控制提供量化指标.为此,本文提出了一种基于信息熵理论的防抱死制动系统性能评估方法.首先对实际滑移率进行状态划分,进而以信息熵理论提出防抱死制动系统性能评估模型.最后应用实例对所提模型进行验证分析,结果表明,基于信息熵的防抱死制动系统模型能够有效量化系统制动性能水平.

The driving environment of the vehicle is complex,and the anti-lock braking system has various working conditions,and its braking performance is susceptible to various uncertain factors.The performance evaluation of the anti-lock braking system can measure the effectiveness of the control strategy and also provide quantitative indicators for feedback control.Aiming at this problem,this paper proposes a performance evaluation method for anti-lock braking system based on information entropy theory.Firstly,the actual slip ratio is divided into states,and then the performance evaluation model of anti-lock braking system is proposed by information entropy theory.Finally,the application example is used to verify the proposed model.The results show that the anti-lock braking system model based on information entropy can effectively quantify the system braking performance level.
