Abstract

The invention discloses an IVI system firmware updating method and device based on mobile storage equipment. The method comprises the steps that updating information carried in an updating file mark in the mobile storage equipment is obtained; an IVI system reads updating environment information which comprises the serial number of the mobile storage equipment, the file list of updating files in the mobile storage equipment and the UUID of the IVI system; and when the updating environment information and the corresponding updating information carried in the updating file mark are matched, IVI system firmware updating is started. The updating file mark is set, related updating information of the UUID of the IVI system, the file list and the serial number of the mobile storage equipment is recorded in the updating file mark, when the read updating environment information and the recorded updating information are matched, updating is started, full-course information verifying during a whole updating process is guaranteed, controllability and safety of the whole updating process are guaranteed, and an updating source and an updating purpose are accurate.

Description

Technical field [0001] The present invention relates to the field of software technology, and 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 Infotaiment, in-vehicle entertainment information system) in-vehicle entertainment information system is generally upgraded through mobile storage devices (including but not limited to U disk / SD card / TF card), which will upgrade the installation package and upgrade the logo file. It is placed in the root directory of the mobile storage device. During the startup of the in-vehicle entertainment information 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 car entertainment system mainly has the following shortcomi...
