Abstract

The invention discloses a method and a device for upgrading IVI system firmware based on a mobile storage device. The method includes: obtaining the upgrade information carried in the upgrade file mark in the mobile storage device; the IVI system reads the upgrade environment information, and the upgrade environment information includes: the serial number of the mobile storage device, the file name of the upgrade file in the mobile storage device list and the UUID of the IVI system; when the upgrade environment information matches the corresponding upgrade information carried in the upgrade file flag, the IVI system firmware starts to upgrade. Set the upgrade file flag, record the upgrade information related to the UUID of the IVI system, the file list and the serial number of the mobile storage device in the upgrade file flag, when the read upgrade environment information matches the recorded upgrade information, start the upgrade, Ensure the verification of the whole process information during the entire upgrade process, ensure that the entire upgrade process is controllable and safe, and the source and purpose of the upgrade are accurate.

Description

technical field [0001] The invention relates to the technical field of software, in particular to a method and device for upgrading IVI system firmware based on a mobile storage device. Background technique [0002] The existing IVI (In Vehicles Infotainment, in-vehicle entertainment information system) in-vehicle entertainment information system generally upgrades the system through mobile storage devices (including but not limited to U disk / SD card / TF card), and the installation package and logo file will be upgraded soon. It is placed under the root directory of the mobile storage device. During the start-up process of the vehicle infotainment system, it is detected that there is an upgrade logo file on the mobile storage device, and the upgrade installation package with the specified name is read according to the agreement to perform the upgrade operation. [0003] The system upgrade method of the existing vehicle entertainment system mainly has the following deficiencie...
