The invention relates to an OTA upgrading system and method for a vehicle-mounted infotainment system. The OTA upgrading system comprises an OTA assembly and the vehicle-mounted infotainment system. A DO/IP protocol stack module of the OTA component is used for realizing interaction of a diagnosis upgrading instruction; the SOME/IP packaging library module of the OTA component is used for realizing HMI interaction and an independent downloading instruction; a DO/IP protocol stack module of the vehicle-mounted infotainment system is used for performing diagnosis instruction interaction when the vehicle-mounted infotainment system is upgraded; the SOME/IP packaging library module of the vehicle-mounted information entertainment system is used for realizing HMI interaction and independent downloading instructions, and can interact with the SOME/IP packaging library of the OTA Master module of the OTA component. According to the method, the vehicle-mounted information entertainment system can be independently downloaded, and the OTA component in the upper computer T-Box controls the self-upgrading of the vehicle-mounted information entertainment system by calling the DO/IP service; and the upgrading mode does not occupy the T-Box memory.
本发明涉及一种车载信息娱乐系统的OTA升级系统及方法,包括OTA组件和车载信息娱乐系统;OTA组件的DO/IP协议栈模块用于实现诊断升级指令的交互;OTA组件的SOME/IP封装库模块用于实现HMI交互和独立下载指令;车载信息娱乐系统的DO/IP协议栈模块用于在车载信息娱乐系统升级时进行诊断指令的交互;车载信息娱乐系统的SOME/IP封装库模块用于实现HMI交互和独立下载指令,可与OTA组件的OTA Master模块的SOME/IP封装库进行交互。本发明使车载信息娱乐系统可独立下载,上位机T‑Box中的OTA组件通过调用DO/IP服务控制车载信息娱乐系统的自升级;升级方式不占用T‑Box内存。
