摘　　要：Boot Loader功能在汽车电子设备开发过程中已经普遍应用,但对于气囊控制单元,此功能仍未普及,但随着市场和消费者对整车安全性的重视逐渐增加,各主机厂对安全零部件的掌控也越来越细化,对气囊控制单元的要求也不再满足于点爆气囊及安全带,因此便产生了多种不同版本的软件,而实现不同软件版本的切换,就需要通过Boot Loader功能来完成。文章介绍了通过Boot Loader实现使用外部测试工具通过诊断服务手段对汽车气囊控制单元更新应用软件功能,具体内容涵盖了在执行Boot Loader功能时所涉及的相关的操作环境及编程步骤。Boot Loader function in the automotive electronic equipment has been widely used in the development process,but for airbag control unit,this function has not been popular,but as the market and consumers increase gradually to the attention of the vehicle safety,to the safety parts in various forms of control is becoming more and more refined,the requirement of the airbag control unit is no longer satisfied with triggering air bags and safety belts,so that it produced a variety of different versions of the software,and realize the different software version of the switch,you need to pass Boot Loader functions to complete.This document gives an overview about the Boot Loader provides the capability of exchanging the application software of the airbag control unit via external tester tools by means of diagnostic services.The specific content covers the relevant operating environment and programming steps involved in executing the Boot Loader function.
