Description

A software upgrade method, system, device and storage medium

technical field

The present invention relates to the technical field of software upgrade, and in particular, to a software upgrade method, system, device and storage medium.

Background technique

In recent years, with the rapid development of Internet technology, changes have taken place in all walks of life, and new changes have also occurred in the automotive industry. Vehicle intelligence and networking have become a new development direction. Compared with the traditional car, the car intelligent car system can realize the automatic upgrade of the on-board software and on-board system on 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 Controllers, battery management systems, etc. When the in-vehicle system needs to update various software, firmware or car ECUs on the car due to increased functions or bug fixes, the intelligent in-vehicle system can upgrade the software, firmware or ECU on the car through the network.

Most of the upgrades of traditional in-vehicle systems need to be upgraded in 4S stores, which greatly reduces the convenience of in-vehicle system upgrades, and at the same time greatly increases the upgrade costs for users and drivers. The intelligent in-vehicle system adopts the method of wireless upgrade, that is, Over-the-air programming (Over-the-air programming, abbreviated OTA) upgrade. The intelligent in-vehicle system can automatically download the upgrade package from the cloud server directly through the network to the vehicle terminal for local upgrade, which can increase the convenience of the system and reduce the upgrade cost, which is also in line with the development trend of automobile intelligence and networking.

OTA is the development trend of automotive software update, which will gradually become popular, but software update has a certain probability of failure. In order to prevent the ECU from not working due to the failure of flashing, the backup scheme is currently used. Generally, two partitions are set in the current backup scheme. : Work area and backup area. When the software needs to be updated, the current software work area and backup area will be updated with a new version. After the backup area is updated, the working software will jump to the backup area, and the original work area will be turned into the backup area. The zone update fails, the workspace still works fine. However, this scheme has great requirements on the storage space of the backup area, and has great requirements on the equipment cost.

Example 1

OTA is the development trend of automotive software update, which 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 ECU of the vehicle controller to not work, the target usually uses backup. Scheme, the current backup scheme generally sets two partitions: 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 backup area is updated, the working software jumps to the backup area. , the original work area is converted into a backup area, so if the update of the backup area fails, the work area can still work normally. However, this scheme has great requirements on the storage space of the backup area, and has great requirements on the equipment cost.

As shown in FIG. 1, an embodiment of this specification provides a software upgrade method, and the specific steps are as follows:

Divide the software work area into at least two work partitions;

Receive software upgrade instructions, download the upgrade package to the backup area, and perform verification work;

According to the software upgrade instruction, the original working partition where the software to be upgraded is located is determined, and the backup area is used as a new working partition to enter a working state, and the original working partition is used as a new backup area.

As for the number of working partitions, it needs to be allocated according to the state of the software, so the number of working partitions can be two, three or even more. It should be noted that the state information of the software includes one or more of software type, software size, and software usage frequency. Of course, other factors must be considered according to the actual situation. Among them, the number and size of working partitions can be adjusted, and the possibility of hardware limitations is not excluded.

It should be noted that the capacity of the working partitions is the same. Only in this way, when the software is upgraded and backed up, any working partition can meet the capacity requirements of the backup area. Therefore, in the initial state, the capacity of the backup area is not less than that of the working partition. The capacity of the partition, in particular, in order to better reflect the requirement for reducing storage space, the capacity of the backup area is equal to the capacity of the working partition.

In order to better illustrate the method provided in this embodiment, as shown in FIG. 2 , the working area is divided into three working partitions A1, A2 and A3, and B is the backup area. As shown in FIG. 3 , the flow of the method provided in this example is shown in FIG. 3 . In the figure, A1, A2 and A3 are the current working software. When the system detects that the software needs to be updated, it will download the upgrade package to the backup area B, and verify it in the backup area B, so that the backup area B meets the requirements of the upgrade software. Work environment, and then use A2, A3 and B as a new software work area, and A1 is converted into a new backup area, the above is a software upgrade workflow.

The software upgrade method provided by this embodiment can reduce the preset capacity of the backup area by setting multiple working partitions, thereby reducing the storage space requirement and saving the cost.
