摘要：【中文】本发明提供了一种车辆识别码刷写方法和车辆识别码刷写系统。其中，车辆识别码刷写方法包括通过手持终端获取汽车底盘的车辆识别码及与车辆识别码相匹配的车载终端码；通过手持终端将车辆识别码与车载终端码进行绑定并生成数据包，上传至生产过程执行管理系统；通过生产过程执行管理系统将数据包中的车辆识别码传输至与数据包对应的车载终端中进行存储；通过车载终端将车辆识别码刷写至发动机电子控制器中。通过本发明的技术方案，可利用生产过程中已在使用的设备和系统对车辆识别码进行传输和刷写，简化了现有操作环节，提高了刷写效率和准确性，有利于降低成本。 【EN】The invention provides a vehicle identification code flashing method and a vehicle identification code flashing system. The vehicle identification code flashing method comprises the steps that a vehicle identification code of an automobile chassis and a vehicle-mounted terminal code matched with the vehicle identification code are obtained through a handheld terminal; binding the vehicle identification code and the vehicle-mounted terminal code through the handheld terminal, generating a data packet, and uploading the data packet to a production process execution management system; transmitting the vehicle identification code in the data packet to a vehicle-mounted terminal corresponding to the data packet for storage through a production process execution management system; and the vehicle identification code is written into the electronic engine controller through the vehicle-mounted terminal. According to the technical scheme, the vehicle identification code can be transmitted and flashed by using equipment and a system which are used in the production process, the existing operation link is simplified, the flashing efficiency and accuracy are improved, and the cost is reduced.
