AI Technical Summary

Technical Problem

During the OTA mass upgrade process, it is impossible to fuse in time, resulting in failure of subsequent vehicles upgrades, resulting in wasting time. If too many parts involving car safety fail, it will also cause greater losses.

Method used

The threshold-based fuseable OTA upgrade method is adopted, and the system intelligently monitors the upgrade status, automatically fuses, and avoids safety accidents by setting threshold parameters and fuse conditions.

Benefits of technology

Automatic fuse is achieved, avoiding time waste and potential security risks caused by the failure of upgrades. The free control system fuse is achieved by reasonably adjusting the threshold, which is extremely scalable.

Abstract

Disclosed in the present invention is a fusible vehicle-end OTA upgrade method based on a threshold, comprising the following steps: configuring a task threshold, setting a fusing condition, and issuing an upgrade task; obtaining version information of a vehicle, and matching an upgrade task for the vehicle; executing the upgrade task of the vehicle, and reporting an upgrade status of the vehicle; comparing the reported upgrade status of the vehicle with the task threshold; and terminating the upgrade task when the task threshold reaches the fusing condition. By setting the threshold parameter and the fusing condition, a system can intelligently monitor the upgrade status, thereby realizing automatic fusing and avoiding safety accidents. By properly adjusting the threshold, the fusing of the system can be freely controlled, making the method extremely expansible.
