Embodiment Construction

[0026] As mentioned above, in the prior art, the OTA upgrade can be completed with the help of Wifi wireless network, mobile phone mobile network or vehicle mobile network, which is equivalent to completing the upgrade with the help of wireless network in the air. In a specific implementation applied to the vehicle domain controller In the mode, the server may send an update request to the vehicle-mounted domain controller to notify the version of the software to be updated, and then the vehicle-mounted domain controller accesses the server to download the software package of the software to be updated, and then adopts the software to be updated Software package for OTA upgrade.

[0027] The inventor of the present invention has found through research that if the data package to be downloaded for the upgrade is not large, we can directly use the mobile network to upgrade, but if it is necessary to download a relatively large upgrade package, it needs to consume more traffic. Ho...

Abstract

The invention discloses a method and a device for upgrading software by a vehicle-mounted domain controller OTA, a storage medium and a terminal. The method comprises the following steps: determiningthat software upgrading needs to be carried out, and determining a version of to-be-updated software; mounting a compiling operation system, selecting environment parameters, and loading a compiling hardware environment, the environment parameters being stored in hardware of the vehicle-mounted domain controller; determining the version of the current software according to the compiling operationsystem; determining and downloading a difference code between the code of the to-be-updated software and the code of the current software, wherein the data volume of the difference code is smaller than that of the software package of the to-be-updated software; in the compiling hardware environment, generating a differentiated executable file by adopting the compiling operation system and the difference code; and upgrading the software by adopting the differentiated executable file OTA. According to the scheme, the downloaded data volume can be far smaller than that in the prior art, consumedflow is remarkably reduced, and the use cost of a user is effectively reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device, a storage medium, and a terminal for OTA software upgrade of a vehicle-mounted domain controller. Background technique [0002] For a system that provides services through the Internet, when a problem that needs to be corrected is found during system operation, such as a bug that needs to be corrected, it needs to be repaired in time to ensure the quality of service. [0003] In the existing space download technology (Over-the-Air Technology, OTA), OTA is a technology for remote management of SIM card data and applications through the air interface of mobile communication. The air interface can use 4G LTE, 5G, 6G, WAP, GPRS, CDMA1X, short message technology, etc. The application of OTA technology enables mobile communication not only to provide voice and data services, but also to provide new service downloads. This kind of online upgrade without ...
