路面车辆推荐操作规程SAEJ1939-01用于公路设备的控制及通信网络推荐操作规程
本系列SAE推荐操作规程是由卡车及客车电子电气委员会所属的卡车及客车控制及通信小组委员会制定的。该小组委员会的目标是针对电控单元的需求、设计和使用，提交信息报告、制定推荐操作规程。这些电控单元在汽车部件之间传递着电子信号和控制信息。本规程的使用不限于卡车和客车应用，其对于其他的应用也可以提供直接的支持，正如已在建筑及农业设备和固定式的动力系统。
本推荐操作规程的最终目标是形成工业标准，因此可能为适应实际应用和技术进步作出经常性的调整。
本推荐操作规程中描述的控制局域网（Controller Area Network，CAN）协议是博世公司（Robert Bosch GmbH，Bosch）的知识产权。博世将给予所有要生产或设计控制局域网电控单元的企业一个证书。只有包含了控制局域网协议的集成芯片或软件的制造商需要办理版权证书的手续，对控制局域网协议的使用并不需要申请证书。有关证书授权的信息和典型应用可以在下述地址获得：

本推荐操作规程的制定是作为在J1708、J1587和J1922推荐操作规程中所完成工作的延续。但J1939系列的推荐操作规程相比上述早期文件提供了更高的性能。
