电动汽车整车控制器BootLoader功能开发

传统的电动汽车整车控制器开发中,对程序的烧写是通过BDM调试接口实现的,该方法不仅在控制器应用程序开发阶段会影响开发效率,而且会给后期整车控制器升级维护造成极大的不便.通过嵌入式系统引导加载程序(即BootLoader)对解决上述问题具有较强的实际意义.本文提出了整车控制器开发中BootLoader功能实现的整套设计与解决方案,并将该方案应用到实车运行中.最后,通过实际应用的测试与分析,结果表明该功能具有极高的可行性与有效性.

Development of BootLoader in Vehicle Control Unit of an Electric Vehicle

The method of downloading program through BDM debugging interface is usually used in the development of vehicle control unit of the electric vehicles in the past , which may not only decrease the efficiency of developing the controller during the development phase , but also be inconvenient to upgrade and maintain the vehicle control unit if there are some bugs found during the operation phase .It may be a considerably practical significance to solve the problem by inviting the function of BootLoader based on embedded system .A complete set of processing solution was provided for the function in the development of vehicle control unit , and made a-vailable in the running test .It was improved to have the excellent practicability and effectiveness by the testing and analysis in operation .
