摘　　要：传统汽车电控单元对程序的烧写一般采用BDM调试接口实现,该方法不仅影响电控单元应用程序的开发效率,而且会给汽车电控单元后期的升级维护带来不便。使用嵌入式启动引导程序(即Bootloader),能够较好的解决上述问题。本文设计并实现了一种应用于汽车电控单元的基于CAN通信的Bootloader。通过实际应用和测试,结果表明该Bootloader能够正确引导程序运行,准确、方便地为控制器下载应用程序。The traditional automotive ECU usually uses BDM debug interface for programming, This method influences the efficiency of developing the ECU, and also makes it difficult for update and maintenance. Using the bootloader for ECU will solve these problems. This paper, presents the design and implementation of a bootloader for automotive ECU, which based on CAN communication. This bootloader is proved that it can boot correctly and program the ECU quickly, through the test and practical application.
