The embodiment of the invention provides an upgrading method of a vehicle-mounted domain controller, the domain controller, a vehicle and a program product, the domain controller comprises an SoC and an MCU, the method is applied to the MCU, and the method comprises the steps that under the condition that a pre-upgrading notification for the domain controller is received, pre-upgrading processing is executed in a default session; the pre-upgrading notification is sent by the SoC based on the domain controller upgrading request; the domain controller upgrading request is sent to the SoC by an upgrading request direction; and executing a preset recovery process in a default session when an upgrade completion notification for the domain controller sent by the SoC is received. The SoC responds to an upgrade request of the domain controller to enter a programming session, and the MCU completes pre-upgrade processing of the domain controller in a default session, so that the working modes between the domain controller and other vehicle-mounted modules are aligned. For the whole vehicle upgrading process, the domain controller enters a programming session in the pre-upgrading stage. For the domain controller, the MCU executes preparatory work of a pre-upgrade stage in a default session, thereby realizing upgrade compatibility.
本申请实施例提供车载域控制器的升级方法、域控制器、车辆及程序产品,域控制器包括SoC与MCU,方法应用于MCU,包括:在接收针对域控制器的预升级通知的情况下,在默认会话中执行预升级处理;预升级通知是SoC基于域控制器升级请求发送的;域控制器升级请求是升级请求方向SoC发送的;在接收SoC发送的针对所述域控制器的升级完成通知的情况下,在默认会话中执行预设的恢复处理。由SoC响应域控制器升级请求进入编程会话,由MCU在默认会话中完成域控制器的预升级处理,从而拉齐了域控制器与其他车载模块之间的工作模式。对于整车升级流程,域控制器在预升级阶段进入了编程会话。对于域控制器是由MCU在默认会话中执行预升级阶段的准备工作,由此实现了升级兼容。
