The invention discloses a vehicle domain controller upgrading method and device, a storage medium and electronic equipment. The method comprises the steps that a main chip in the vehicle domain controller downloads an upgrading data packet used for upgrading the vehicle domain controller, and the vehicle domain controller is a multi-core heterogeneous controller provided with a plurality of chips including the main chip; the upgrading data packet comprises upgrading mirror image data used for respectively upgrading each sub-chip in a plurality of sub-chips connected with the main chip; in response to an upgrade operation on the vehicle domain controller, the main chip identifies upgrade mirror image data corresponding to each sub-chip based on a mirror image classification mark carried in the upgrade data packet to obtain a plurality of pieces of upgrade mirror image data; the main chip sends the multiple pieces of upgrading mirror image data to the corresponding sub-chips, and the sub-chips conduct asynchronous parallel upgrading through the upgrading mirror image data of the sub-chips. The technical problem that the upgrading efficiency of the vehicle domain controller is low is solved.
本申请公开了一种车辆域控制器的升级方法和装置、存储介质及电子设备。其中,该方法包括:车辆域控制器中的主芯片下载用于升级车辆域控制器的升级数据包,其中,车辆域控制器为配置有包含主芯片在内的多个芯片的多核异构控制器,升级数据包中包括用于对与主芯片连接的多个子芯片中的各个子芯片分别进行升级的升级镜像数据;响应于对车辆域控制器的升级操作,主芯片基于升级数据包中携带的镜像分类标记,识别出与每个子芯片各自对应的升级镜像数据,得到多个升级镜像数据;主芯片将多个升级镜像数据分别发送给对应的子芯片,其中,各个子芯片将利用各自的升级镜像数据进行异步并行升级。本申请解决了车辆域控制器的升级效率较低的技术问题。
