Abstract: In this paper, a heavy-duty commercial vehicle is taken as an object, and an intelligent vehicle load system based on SAE J1939 is developed.The system through the CAN bus real-time engine EMS sharing the actual torque, friction torque, accelerator pedal, speed and other data, according to the principle of vehicle dynamics calculation of vehicle load, according to the discrete correction strategy and compensation strategy for data display and modification, vehicle load information sent to the instrument interface and car Networking Background through the CAN bus.The system provides reference for the driver's self inspection and vehicle load supervision departments, and has some significance for reducing the overloading of vehicles. It can also help the fleet management to confirm whether the driver is pulling or unloading the goods without permission.

前言
现有的商用车称重系统需要在工作人员安排下到具体地点使用相应的称重系统完成，无法满足及时称重的需要，对于货物的装卸，监管部门想要实时的掌握车毁状态，则需要在车上家装加号装车辆载重系统，而传统的车辆智能载重主

要是通过增加载重传感器进行数据采集、数据处理、分析，该方案需额外增加控制器成本高，易损坏、易被人为破坏，增加零部件及线束隐患点；同时不同车型需重新布置，通用性差：随着汽车电子技术的发展，为了提高信号的利用率及资源共享，传统控制方式已远远不能满是这种需求。CAN总线和基于它的总线通信标准提供了解决上述间题的途径。本文基于当前车辆载重系统管理的现实需求，利用汽车动力学
