Vehicle terminal and firmware function perfecting method thereof

Abstract

The invention provides a vehicle terminal and a firmware function perfecting method thereof. The vehicle terminal sends current firmware information to a mobile terminal in a short-distance communication mode, receives a data packet corresponding to the current firmware information fed back by the mobile terminal, and then performs updating according to the data packet sent by the mobile terminal, so that the data packet can be acquired from the mobile terminal in the short-distance communication mode and updating can be performed in the absence of an external memory, and then the updating efficiency is improved. The data packet is acquired from a server by the mobile terminal via the following steps: the mobile terminal sends the firmware information to the server, the server judges a firmware version to update according to the firmware information, the server sends a data packet corresponding to the firmware version to the mobile terminal, and the mobile terminal decompresses and verifies the data packet. The mobile terminal plays a role of transferring in the process that the vehicle terminal acquires the data packet, verifies the data packet, and sends the data packet passing the verification to the vehicle terminal, so that the updating security is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle-mounted terminals. Specifically, the present invention relates to a method for improving firmware functions of a vehicle-mounted terminal and the vehicle-mounted terminal. Background technique [0002] Vehicle-mounted terminals, such as driving recorders, smart rearview mirrors, vehicle-mounted navigators, etc., usually have their operating systems. In its operating system, it includes various firmware, such as Camera, WiFi, Bluetooth and other firmware. Since the vehicle-mounted terminal is usually left on the car, when these vehicle-mounted terminals need to update the firmware, it is usually necessary to use an external memory such as a U disk to connect to the vehicle-mounted terminal, and the vehicle-mounted terminal reads the update file in the external memory to update the firmware. In this firmware update method, the update file first needs to be placed in the external memory, and...

AI Technical Summary

Problems solved by technology

In this firmware update method, the update file first needs to be placed in the external memory, and then the external memory is connected to the vehicle terminal, and the vehicle terminal reads the update file to update. The process is complicated, wastes time, and is inefficient.

[0003] In addition, if the vehicle-mounted terminal is updated, if power failure occurs, the update file is damaged, etc., the firmware update will fail, which may cause some applications of the vehicle-mounted terminal to be abnormal or even fail to start the system normally. At this time, it is impossible to return to the firmware and system before the update.

If the system cannot be started normally, the update cannot be continued. It can only be sent to the product maintenance point or the manufacturer for re-erasing the firmware, which will affect the use

[0004] Therefore, the traditional vehicle terminal has the problems of poor update efficiency and poor security
