Abstract

The invention provides an OTA upgrading method and device, and relates to the technical field of automobile software upgrading. The method comprises the following steps: testing to-be-upgraded target software to obtain a test result; obtaining an upgrade package of the target software according to the test result; according to the upgrade package of the target software, determining a function type to which the target software belongs; and according to the function type to which the target software belongs, determining a corresponding upgrading mode to carry out OTA upgrading on the target software. According to the scheme, testing personnel allocation can be reduced, testing vehicle resources are saved, the testing period is shortened, then the software release period is accelerated, and the usability and reliability of software are improved.

Description

technical field [0001] The invention relates to the technical field of automobile software upgrade, in particular to an OTA upgrade method and device. Background technique [0002] With the communication and interaction between smart devices and smart cars, the integration and version update of multiple data sources in the Internet of Vehicles has become a problem that car manufacturers and related standards departments need to solve. It is crucial to consider how to use advanced OTA (Over-the-Air Technology, over-the-air technology) to update the electronic controller's software during the entire vehicle life cycle. [0003] With the rapid development of new energy vehicles and the continuous updating of software versions, the traditional electronic and electrical architecture has a large number of ECUs (electronic control units) with scattered functions, complex in-vehicle communication networks, frequent and necessary ECU software upgrades, and a long time for comprehensi...
