Embodiment 1

[0047] OTA is the development trend of automobile software update, and it is more and more valued by the majority of manufacturers. However, due to the certain failure probability of software update, in order to prevent the failure of software flashing and cause the vehicle controller ECU to fail to work, the target usually adopts 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.

[0048] Such as figure 1 As shown, an embodiment of this specification provides a met...

Abstract

The invention discloses a software upgrading method and device, equipment and a storage medium. The method comprises: dividing a software working area into at least two working subareas; receiving a software upgrading instruction, downloading the upgrading package to a backup area, and performing verification work; according to the software upgrading instruction, determining the original working partition where the to-be-upgraded software is located, taking the backup area as a new working partition to enter the working state, and taking the original working partition as a new backup area. Byarranging the multiple working partitions, the preset capacity of the backup area can be reduced, so that the storage space requirement is reduced, and the cost is saved.

Description

technical field [0001] The present invention relates to the field of software upgrade technology, in particular to a software upgrade method, device, 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 cars, the smart car system can automatically upgrade the on-board software and on-board systems of the car, including the upgrade of the vehicle controller (ECU) of each control unit on the car, 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 the software, firmware or EC...
