[0044] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0045] The AB partition is to divide the storage space of the ECU into two independent areas, i.e. A area and B area. The two areas are physically or logically isolated to ensure the independence and security of data. Each area can store a complete software version and can run independently when needed.

[0046] A and B zones store different software versions, which differ in content. This difference allows the ECU to selectively load and execute the software version of one of the zones at runtime. If the currently running software version (e.g. A zone) has problems or needs to be updated, the ECU can switch to the software version of the other zone (e.g. B zone) to continue running. This provides the ability of fault recovery, ensuring the normal operation of the vehicle is not affected. Through AB partitioning, the ECU can achieve seamless software upgrades. During the upgrade process, the new software version can be downloaded and stored in the unused zone (e.g. B zone), and then switched to the new version for running at the appropriate time.

[0047] The differential upgrade is to compare the differences between the old and new versions, and only transmit and update the changed part of the data to the target device. It is based on a differential algorithm that can accurately identify the differences between the two versions and generate a data packet containing these differences, i.e. a differential packet. After the ECU receives the differential packet, it is stored in the unused zone, i.e. B zone. The version restoration needs to be based on the old version software of A partition, and this process may involve file replacement, modification or addition, etc. After applying the differential packet, version verification is performed, and after verification, the ECU can switch to the new version software for running, i.e. switch to B zone. Usually, it is done at the appropriate time such as vehicle shutdown, restart or specific maintenance period, and the switching process needs to ensure the stability and reliability of the system to avoid affecting the normal operation of the vehicle. If the differential upgrade of AB partitioning is performed during the normal operation of the vehicle, it cannot achieve no-sense upgrade.

[0048] For ease of understanding, first describe the system to which the present application is applicable. The software upgrade method provided by the present application can be applied to, for example Figure 1As shown in the electronic controller, wherein the electronic controller 100 comprises an internal memory 111 and an external memory 112 added outside the internal memory 111, the internal memory 111 is a partitioned memory, comprising an active partition 111-1 and an inactive partition 111-2, the active partition 111-1 corresponds to the A partition, and the inactive partition 111-2 corresponds to the B partition, and the external memory 112 can be an external flash. The electronic controller 100 is used to save the differential package to the external memory when receiving the differential package of the software to be upgraded, determine the upgrading mode of the software to be upgraded according to the software type of the software to be upgraded in the active partition and the external memory, the software type comprises the current version software, and when the upgrading mode of the software to be upgraded is differential upgrading, generate the latest version software according to the differential package and the current version software. The external memory 112, the active partition 111-1 and the inactive partition 111-2 are used to store any version software of the software to be upgraded in the upgrading process, wherein the active partition 111-1 is mainly used to store the software running in the system, and the inactive partition 111-2 is mainly used to store the software not running in the system, which comprises the latest version software. The electronic controller 100 is used to copy the latest version software in the external memory 112 to the active partition 111-1 according to the boot file of the internal memory 111 and the inactive partition 111-2, and determine the software type in the external memory 112 and the active partition 111-1 according to the running state of the latest version software in the active partition 111-1, so as to facilitate the next software upgrading.

[0049] In the system architecture as shown in the figure, Figure 2 In the system architecture as shown in the figure, the vehicle 200 comprises a vehicle terminal 210, and the electronic controller 100 can be arranged in the vehicle terminal 210, wherein the vehicle terminal 210 can be, but is not limited to, various personal computers, notebook computers connected with the vehicle.

[0050] Figure 3 A flowchart of a software upgrading method provided by the embodiment of the application, which can be executed by the electronic controller 100 as shown in the figure. Figure 1 As shown in the figure, the method can comprise the following steps: Figure 3 As shown in the figure, the method can comprise the following steps:

[0051] S310, in response to the electronic controller receiving the differential package of the software to be upgraded, saving the differential package to the external memory.

[0052] The to-be-upgraded software can be software related to the vehicle, for example, software related to the cockpit and intelligent driving. When it is determined that the software needs to be upgraded, full upgrade and differential upgrade can be adopted. When differential upgrade is adopted, a differential package is obtained by performing differential calculation according to the current version and the target version of the vehicle in advance. The calculation process of the differential package is to generate file snapshots of the current version and the target version, to determine the differential part by comparing the files of the two versions, to identify the differential part by using the file snapshots, and to generate the differential package.

[0053] After the electronic controller receives the differential package of the to-be-upgraded software, the to-be-upgraded software is differentially upgraded, the differential package is saved to the external storage, the software type in the external storage is consistent with the software type in the active partition, and the latest version software is restored based on the differential package and the current version software. Saving the differential package to the external storage can ensure that the latest version software is restored, that is, the software in the active partition and the non-active partition is different, and that the current version software in the active partition can be differentially upgraded.

[0054] S320, according to the software type of the to-be-upgraded software in the active partition and the external storage, determining the upgrade mode of the to-be-upgraded software.

[0055] The software type can include the current version software and the latest version software, and the current version software is an old version software compared with the latest version software. The upgrade mode includes differential upgrade and full upgrade. Since the generation of the latest version software needs to be based on the current version software and the differential package, if the software types in the active partition and the external storage are different versions of the to-be-upgraded software, differential upgrade cannot be performed, and full upgrade can be performed.

[0056] S330, when the upgrade mode of the to-be-upgraded software is differential upgrade, generating the latest version software in the external storage according to the differential package and the current version software.

[0057] S340, based on the boot file of the internal storage, switching the latest version software in the external storage from the non-active partition to the active partition.

[0058] The boot file contains necessary information and instructions for starting the operating system, such as the file address of the software package, and is mainly responsible for loading the operating system to ensure that the system can correctly perform the boot process and can determine the system partition.

[0059] When differential upgrade is performed, the latest version software in the external storage is first copied to the non-active partition, and then the partition pointed to by the boot file is switched, the switching between the active partition and the non-active partition is completed, the software type of the active partition is updated to the latest version software, and differential upgrade is realized.

[0060] S350, according to the running state of the latest version software in the active partition, determining the software type in the external memory and the active partition, so as to facilitate the next software upgrade.

[0061] After the software to be upgraded completes the upgrade, the latest version software may not run normally, and the running state thereof affects the next software upgrade. In order to ensure that each software upgrade can be performed normally, the software type in the external memory and the active partition needs to be determined according to the running state of the latest version software. If the software type in the external memory and the active partition cannot accurately complete the software upgrade, the software type needs to be adjusted.

[0062] By additionally arranging the external memory outside the internal memory of the electronic controller to store the same version software as the active partition, the hardware cost is low, and in the meanwhile, it ensures that the differential upgrade process can be performed without sensing and ensures that the non-active partition can provide rollback protection for the active partition, thereby improving the user experience of remote upgrade.

[0063] As an implementable manner, according to the software type of the software to be upgraded in the active partition and the external memory, the upgrade mode of the software to be upgraded is determined, comprising:

[0064] When the software type of the software to be upgraded in the active partition and the external memory is the same, the upgrade mode of the software to be upgraded is determined as differential upgrade.

[0065] When the software type of the software to be upgraded in the active partition and the external memory is different, the upgrade mode of the software to be upgraded is determined as full upgrade.

[0066] When the software type of the software to be upgraded in the active partition and the external memory is the same, it indicates that the old version software matching the differential package exists in the external memory, and differential upgrade can be performed, and the upgrade mode of the software to be upgraded is determined as differential upgrade.

[0067] When the software type of the software to be upgraded in the active partition and the external memory is different, it indicates that the old version software matching the differential package does not exist in the external memory, and differential upgrade cannot be performed, and the upgrade mode of the software to be upgraded is determined as full upgrade. By judging whether the software type of the software to be upgraded in the active partition and the external memory is the same, the upgrade mode of the software to be upgraded can be determined, so as to ensure that the software type of the software to be upgraded in the active partition and the external memory is the same when the next differential upgrade is performed. Especially when the software version is rolled back, the software versions of the external memory and the active partition need to be synchronized, and this process needs time. In order to avoid that the synchronization is not completed before the next differential upgrade, the differential upgrade is performed only when the software versions of the external memory and the active partition are the same.

[0068] As an implementable manner, based on the boot file of the internal memory, the latest version software in the external memory is switched from the non-activated partition to the activated partition, including:

[0069] copying the latest version software in the external memory to the non-activated partition;

[0070] switching the software types of the software to be upgraded in the activated partition and the non-activated partition according to the boot file of the internal memory, so as to switch the latest version software in the external memory to the activated partition.

[0071] Since the software running in the activated partition can be stopped according to user demand, and the software not running in the non-activated partition can be started according to user demand, the switching of the activated partition and the non-activated partition can be realized through the corresponding boot file of the internal memory, that is, the software stopped running in the activated partition can be divided to the non-activated partition, and the software started running in the non-activated partition can be divided to the activated partition.

[0072] restoring the differential package and the current version software in the external memory to the latest version software, and completing installation. After the external memory is written, the latest version software is copied to the non-activated partition. At this time, the latest version software is the software not running, and the current version software is the software running. According to the boot file of the internal memory, the software types of the software to be upgraded in the activated partition and the non-activated partition are switched, so as to realize the software upgrade or rollback in the activated partition and the non-activated partition.

[0073] Specifically, according to the file address of the software in the boot file of the internal memory, the latest version software in the non-activated partition is switched to the activated partition, and the current version software in the activated partition is switched to the non-activated partition. After the electronic controller is restarted, the software completes updating. When rollback occurs, the electronic controller needs to copy the software in the activated partition to the external memory, so as to facilitate the differential upgrade next time.

[0074] As an implementable manner, according to the running state of the latest version software in the activated partition, the software types in the external memory and the activated partition are determined, including:

[0075] If the activated partition runs the latest version software abnormally, the software types in the activated partition and the external memory are restored from the latest version software to the current version software.

[0076] If the activated partition runs the latest version software abnormally, it indicates that the software of this version cannot be used as the old version software for next software upgrade. The software types in the activated partition and the external memory are restored from the latest version software to the current version software.

[0077] Specifically, the current version of the software in the inactive partition and the latest version of the software in the active partition are rolled back, so that the latest version of the software in the active partition is restored to the current version. The current version of the software in the active partition is then synchronized to the external storage, so that the latest version of the software in the external storage is restored to the current version. At this point, the software in the active partition and the external storage is the same version, which facilitates the next differential upgrade, while the inactive partition contains the previous version, which facilitates software rollback.

[0078] As one feasible approach, the software types in the external storage and the active partition are determined based on the running status of the latest version of the software within the active partition, including:

[0079] If the latest version of the software runs normally on the active partition, it confirms that both the external storage and the software in the active partition are the latest versions.

[0080] If the latest version of the software runs normally on the active partition, it means that this version of the software can be used as the old version for the next software upgrade. The latest version of the software is kept in the external storage and the active partition to facilitate the next differential upgrade.

[0081] It should be understood that, although Figure 3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated in this application, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Furthermore, Figure 3 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0093] As an implementable manner, the determining module 420 is further specifically configured to determine that the software type in the external storage and the software type in the active partition are both the latest version software if the activation of the partition running the latest version software is normal.
