Embodiment Construction

[0011] The present invention will be described in further detail in conjunction with the following, so that those skilled in the art can implement it with reference to the description.

[0012] In the method for controlling OTA rollback of the on-board controller of the present invention, a startup storage unit and a backup storage unit for storing the controller program executed by the on-board controller are set. And when the vehicle leaves the factory, only the controller program that can be executed by the on-board controller is stored in the startup storage unit, and the controller program is not stored in the backup storage unit. In this way, before the vehicle performs the initial OTA upgrade, the on-board The controller controls the vehicle by executing the controller program stored in the boot storage unit at the factory.

[0013] In the subsequent OTA upgrade process, the data obtained through OTA is used to upgrade the current controller program in the startup stora...

Abstract

The invention discloses a control method for OTA rollback of a vehicle-mounted controller. The control method comprises the following steps: setting a start storage unit and a backup storage unit which are used for storing controller programs executed by the vehicle-mounted controller; if the current controller program stored in the starting storage unit can be executed by the vehicle-mounted controller, the vehicle-mounted controller executes the current controller program and compresses and stores the controller program of the previous version of the current controller program in the backup storage unit; if the current controller program stored in the starting storage unit cannot be executed by the vehicle-mounted controller, the controller program of the previous version of the current controller program stored in the backup storage unit is decompressed and rolled back to be executed by the vehicle-mounted controller. According to the OTA rollback control method for the vehicle-mounted controller, it can be ensured that the vehicle-mounted controller can always obtain the controller program capable of being executed so as to ensure normal running of the vehicle.

Description

technical field [0001] The present invention relates to a control method, in particular to a control method for OTA (OvertheAirTechnology, over-the-air technology) rollback of a vehicle-mounted controller. Background technique [0002] At present, some vehicles are equipped with an on-board controller OTA upgrade function to obtain the latest controller program, and use the updated controller program to control the vehicle. [0003] However, there is also the possibility of failure when using OTA upgrades. If the OTA upgrade fails, there will be no programs that can run in the on-board controller, and the on-board controller will not work. The loss of the function of the on-board controller will affect the comfort of the vehicle when it is slight, and cause the vehicle to be unable to drive when it is serious. Contents of the invention [0004] Aiming at the disadvantages of the prior art, the present invention provides a method for controlling OTA rollback of a vehicle-...
