Problems solved by technology

However, if there are some problems during the upgrade process, such as sudden power failure of the device, removal of the mobile device, damage to the mobile device, system failure, etc., resulting in an upgrade failure, the instrument panel cannot be restarted to work normally, and needs to be returned to the factory for processing
It brings inconvenience to users, and there will be certain security risks at the same time.

Abstract

The invention relates to the field of vehicle control, in particular to a vehicle instrument panel upgrading system and method. An instrument panel hard disk is subjected to partition backup, so thata complete instrument panel system file is obtained; under the condition that, in an instrument panel system upgrading process, instrument panel upgrading fails due to one or more factors of power failure of an instrument panel, pullout of a mobile device, damage of the mobile device and a system fault, the instrument panel is powered on again, and an instrument panel system can be restored to a system before upgrading according to the system file summarized by backup partitions in the instrument panel hard disk, so that the normal operation of the instrument panel system is ensured, the repair work of the instrument panel is reduced, and the user experience is improved. In addition, after the state of the instrument panel system before upgrading is restored, if the mobile device is recognized and an upgrading file is scanned, the instrument panel system can continue to be upgraded; and compared with the prior art, the upgrading system is more convenient and reliable.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a vehicle instrument panel upgrading system and an upgrading method thereof. Background technique [0002] The car dashboard software architecture includes uboot files, operating system kernel files, QT car dashboard applications, MCU applications, DTB files and rootfs file systems. [0003] The uboot file is a part of the linux operating system. It is the first to initialize the IMX6 processor hardware and start the operating system kernel file. [0004] The operating system kernel file is an essential core module of the linux operating system. It is used to build the operating system, initialize various services and driver modules of the linux operating system, ensure the stable operation of the system, and mount the rootfs file system. [0005] The rootfs file system is a file system used to ensure the environment required for storing QT car dashboard applications and ensuring ...
