制动器电子控制模块(制动器 ECM)

制动器电子控制模块(制动器 ECM)位于驾驶室前方仪表板下面。 制动器电子控制模块(制动器 ECM)是制动电控系统中的主要部件。 制动器 ECM 控制自动缓速器控制(ARC)和牵引力控制系统(TCS)的功能。 制动器 ECM 采用多个输入信号和输出信号。 制动器 ECM 从不同输入部件接收信息。 制动器 ECM 利用这些信息来确定是否应该为 ARC 接合行车和减速制动器或未 TCS 接合停车和辅助制动器。 然后,输出部件启动,以施加 ARC 或 TCS。 制动器 ECM 的输入和输出与机器线束相连。

有关 ARC 或 TCS 系统的更多信息,请参考本维修手册中的系统操作, "制动器阀(后行车制动器、缓速器控制、牵引力控制)"。

CAT 数据链路 用于与机器上的其它电子控制模块进行通信。 CAT 数据链路具有双向通信能力。 双向数据链路使 ECM 能够接收信息和发送信息。 CAT 数据链路 可实现与其它电子控制装置共享信息。 Cat 数据链路用来与以下系统共享信息:

  • 发动机电子控制模块

  • 动力传动系电子控制模块

  • 路况分析电子控制模块

  • 重要信息管理系统
