摘要
在变速箱控制器(TCU)控制软件的设计和研发过程中,为了快速、便捷地对控制器软件进行软件升级,参照整车厂的诊断规范和软件升级规范要求,基于UDSon CAN协议设计了一种Bootloader方案,并对该方案进行多次测试和验证。结果表明:该Bootloader方案实现了基于CAN总线的IAP在线升级,完全符合统一诊断规范要求,整个刷新流程快速稳定,拓展性极高。
In the process of design and development of transmission controller(TCU) control software, in order to upgrade the controller software quickly and conveniently, a Bootloader scheme was designed based on UDSon CAN protocol according to the diagnostic specifications and software upgrade specifications of the vehicle manufacturer, and the scheme was tested and verified for many times. The results show that the Bootloader solution realizes the online upgrade of IAP based on CAN bus, it meets the requirements of unified diagnostic specifications,the entire refresh process is fast, stable and highly expandable.
