摘要本文主要研究内容是汽车检测线制动工位测控系统的研制。GB7258—2007《机动车运行安全技术条件》中对汽车制动系统提出了主要技术条件,规定了台式检验制动性能的检测项目及相关标准。根据要求设计了总体方案，根据检测实际环境和技术要求具体设计了系统硬件和软件。首先，在确立了对汽车制动性能参量检测及控制的总体方案后，根据各个参量的特点设计了硬件检测电路。第二部分对软、硬件的可靠性设计、抗干扰措施等方面进行了研究。第三部分研究了本系统所采用的数据处理方法。包括FIR数字滤波算法。最后一部分对制动力测控系统进行了系统调试和性能试验，用前面提到的数据处理方法处理实验数据结果达到预期要求。关键词：汽车制动性测控检测系统抗干扰数字滤波FIRABSTRACTThisthesisdesignsautomobilebrakingperformanceinspectingandcontrolsystem.Someprimarytechnicalqualificationofautomobilebrakinghasbeenbroughtforwardin
