The invention relates to a diagnosis refreshing system and method for a main node of a vehicle-mounted system. The diagnostic refresh system of the main node of the vehicle-mounted system comprises a first core on which a first operating system runs, and the first core comprises a remote refresh module for generating remote refresh request data; a diagnostic record port (DLC) for generating DLC refresh request data and/or diagnostic request data; and a second core on which a second operating system runs, and which includes a data processing module for processing remote refresh request data and/or DLC refresh request data and/or diagnostic request data. The method for refreshing the main node of the vehicle-mounted system comprises the following steps of: receiving DLC (Data Link Control) refreshing request data from a diagnosis record port and/or remote refreshing request data from a remote refreshing module in a first core; processing the DLC refreshing request data and the remote refreshing request data; and sending the processed remote refresh request data to an operating system interface module in the first core.
本发明涉及车载系统主节点的诊断刷新系统及方法。车载系统主节点的诊断刷新系统包括:第一核,在第一核上运行有第一操作系统,并且第一核包括用于产生远程刷新请求数据的远程刷新模块;诊断记录口DLC,其用于产生DLC刷新请求数据和/或诊断请求数据;以及第二核,在第二核上运行有第二操作系统,并且第二核包括用于处理远程刷新请求数据和/或DLC刷新请求数据和/或诊断请求数据的数据处理模块。车载系统主节点的刷新方法包括以下步骤:接收来自诊断记录口的DLC刷新请求数据和/或来自第一核中的远程刷新模块的远程刷新请求数据;对DLC刷新请求数据和远程刷新请求数据进行处理;以及将处理后的远程刷新请求数据发送至第一核中的操作系统接口模块。
