Embodiment 1

[0046] OTA is the development trend of automobile software update, and it is more and more valued by the majority of manufacturers. However, because software update has a certain probability of failure, in order to prevent the failure of software flashing and cause the vehicle controller ECU to fail to work, the target usually adopts a backup In the current backup scheme, two partitions are generally set up: the work area and the backup area. When the software needs to be updated, the current software work area and the backup area are updated with a new version. After the update of the backup area is completed, the working software jumps to the backup area , the original workspace is converted to the backup area, so if the update of the backup area fails, the workspace can still work normally. However, this solution requires a lot of storage space in the backup area, as well as equipment costs.

[0047] Such as figure 1 As shown, an embodiment of this specification provides a...

Abstract

The invention discloses a software upgrading method, device, equipment and storage medium. The method comprises: dividing the software working area into at least two working areas; receiving software upgrading instructions, downloading the upgrading package to the backup area, and performing verification Work; according to the software upgrade instruction, determine the original work partition where the software to be upgraded is located, and use the backup area as a new work partition to enter the working state, and the original work partition is used as a new backup area. The preset capacity of the backup area can be reduced, thereby reducing storage space requirements and saving costs.

Description

technical field [0001] The invention relates to the technical field of software upgrading, in particular to a software upgrading method, system, equipment and storage medium. Background technique [0002] In recent years, with the rapid development of Internet technology, all walks of life have undergone changes, and new changes have also appeared in the automobile industry. Intelligent and networked automobiles have become a new development direction. Compared with traditional automobiles, the intelligent vehicle-mounted system of automobiles can automatically upgrade the vehicle-mounted software and systems, including the upgrade of the vehicle controller (ECU) of each control unit in the vehicle, such as the vehicle controller, body control module, motor controller, battery management system, etc. When the in-vehicle system needs to update various software, firmware or ECU in the car due to function increase or Bug repair, the intelligent in-vehicle system can upgrade th...
