Description

Technical Field

[0001] This invention relates to the field of vehicle software upgrade technology, and more specifically, to a method for remotely upgrading autonomous driving software for tractor-trailers. Background Technology

[0002] With the improvement of people's living standards, vehicles have become an indispensable means of transportation. Vehicles include various hardware devices, such as control and navigation systems, which contain software programs. To ensure normal vehicle operation, the software of these hardware devices needs to be upgraded. Furthermore, OTA (Over-The-Air) functionality for mobile vehicles refers to over-the-air download technology, enabling remote software management through mobile communication interfaces. OTA not only provides a more convenient way to upgrade vehicles but also allows consumers to experience a more intelligent and convenient experience. OTA upgrades can be divided into firmware upgrades and software upgrades. With the rapid development of new energy vehicles in recent years, OTA has brought even more convenient vehicle upgrades. However, existing OTA upgrades require the mobile vehicle to be driven to a fixed location for software upgrades, and all functional modules of the mobile vehicle need to be activated during the upgrade, reducing the convenience of software upgrades and increasing energy consumption. In addition, the above upgrade methods require a dedicated person to manually operate a computer to copy firmware, select files, update, verify, and record modules one by one, resulting in low efficiency. In addition, in the above upgrade method, all software updates, verifications and recording operations are done manually. Due to the influence of personnel quality, ability and work status, problems such as incorrect upgrade versions, incorrect upgrades, and omissions are prone to occur, resulting in a high error rate.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides a method for remotely upgrading the autonomous driving software of a tractor, which has the following beneficial effects:

[0023] This invention provides a vehicle software upgrade method, apparatus, device, and storage medium. It receives a flashing request from an onboard gateway via a System-on-a-Chip (SoC) to determine if the vehicle's current state meets the software upgrade conditions. If the current state meets the conditions, the software upgrade package is obtained through multiple diagnostic services on the SoC via inter-process communication (IPC). Furthermore, this invention acquires vehicle status data in real time and calculates an upgrade status evaluation coefficient based on this data. The upgrade status evaluation coefficient and a preset threshold are used to determine whether to issue a warning. Warnings are issued to the user when the network is poor or the battery is low, solving the problem of upgrade interruption or failure due to poor network or low battery. This allows for automatic software upgrades, eliminating unnecessary manual operation time. Personnel can perform other tasks during the automatic upgrade process, improving not only the efficiency of software upgrades but also indirectly increasing the production line's cycle time.
