Abstract

The invention discloses a vehicle-mounted controller OTA upgrading method, which comprises the following steps that: a vehicle-mounted OTA terminal upgrades after acquiring upgrading information from an OTA platform, issues the upgrading information to a controller to be upgraded, and executes a first security policy based on data backup when upgrading fails; after the to-be-upgraded controller receives the to-be-upgraded information, the to-be-upgraded controller executes an upgrading process, executes a second security policy based on dual redundancy after upgrading fails, and feeds back an upgrading result to the vehicle-mounted OTA terminal; and the vehicle-mounted OTA terminal reports the upgrading result of the vehicle-mounted OTA terminal and the upgrading result of the controller to be upgraded to the OTA platform. According to the OTA upgrading method for the vehicle-mounted controller, efficient and safe data backup in the upgrading process is achieved through the first safety strategy and the second safety strategy, the upgrading success rate is increased, the reliability and stability of OTA upgrading of the vehicle-mounted controller can be improved, and the vehicle-mounted controller can still ensure that the vehicle can be normally started and run when upgrading fails.

Description

technical field [0001] The invention relates to the technical field of automotive software upgrades, in particular to an OTA (Over the Air) upgrade method for a vehicle-mounted controller. Background technique [0002] With the advancement of the new four modernizations of automobiles, namely "electrification, networking, intelligence, and sharing", its electronic procedures are getting higher and higher, and the cost of automotive electronics is gradually increasing in the cost of the whole vehicle. New energy vehicles are more obvious than traditional vehicles. Improve a lot. [0003] "Software-defined cars" has become the development trend of cars, and the complexity of car software has also increased significantly. It is difficult to give users the best experience through 4S upgrades for repairing software faults and updating personalized customization requirements. Therefore, many car companies have established their own OTA upgrade platforms and upgrade methods. The c...
