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

[0045] AB partitioning is to divide the storage space of ECU into two independent areas, namely area A and area B. These 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] Area A and Area B store different software versions respectively, which differ in content. This difference allows the ECU to selectively load and execute the software version in one of the areas during operation. If the currently running software version (such as Area A) has a problem or needs to be updated, the ECU can switch to the software version in another area (such as Area B) to continue running. This provides fault recovery capabilities to ensure that the normal operation of the vehicle is not affected. Through the AB partition, the ECU can achieve seamless software upgrades. During the upgrade process, the new software version can be downloaded and stored in an unused area (such as Area B), and then switched to the new version at the appropriate time.

[0047] Differential upgrade is to compare the differences between the new and old 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, namely a differential packet. After receiving the differential packet, the ECU stores it in an unused area, namely area B. When restoring the version, it needs to be restored based on the old version of the software in partition A. This process may involve operations such as replacing, modifying or adding files. After applying the differential package, the version is verified. After the verification passes, the ECU can switch to the new version of the software, that is, switch to area B. It is usually carried out at an appropriate time such as when the vehicle is turned off, restarted or in a specific maintenance cycle. 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 the AB partition is performed during the normal operation of the vehicle, a senseless upgrade cannot be achieved.

[0048] For ease of understanding, the system to which this application is applicable is first described. The software upgrade method provided in this application can be applied to Figure 1The electronic controller shown. The electronic controller 100 includes an internal memory 111 and an external memory 112 added outside the internal memory 111. The internal memory 111 is a partitioned memory, including an active partition 111-1 and an inactive partition 111-2. The active partition 111-1 is equivalent to the A partition, and the inactive partition 111-2 is equivalent to the B partition. 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. 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. The software type includes the current version of the software. When the upgrade mode of the software to be upgraded is differential upgrade, the latest version of the software is generated according to the differential package and the current version of the software. The external memory 112, the active partition 111-1 and the inactive partition 111-2 are used to store any version of the software to be upgraded during the upgrade 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, including the latest version of the software. The electronic controller 100 is used to copy the latest version of the 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 types in the external memory 112 and the active partition 111-1 according to the running status of the latest version of the software in the active partition 111-1, so as to facilitate the next software upgrade.

[0049] In such Figure 2 In the system architecture shown, the vehicle 200 includes an on-board terminal 210 , and the electronic controller 100 may be disposed in the on-board terminal 210 , wherein the on-board terminal 110 may be, but is not limited to, various personal computers and laptop computers connected to the vehicle.

[0050] Figure 3 A flowchart of a software upgrade method provided in an embodiment of the present application, the method can be performed as follows Figure 1 The electronic controller 100 shown in FIG. Figure 3 As shown, the method may include 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 software to be upgraded may be vehicle-related software, 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 used. When differential upgrade is used, differential package is obtained by differential calculation based on the current version and target version of the vehicle in advance. The calculation process of differential package is to generate file snapshots of the current version and target version, determine the difference by comparing the files of the two versions, use file snapshots for comparison, identify the difference and generate differential package.

[0053] After the electronic controller receives the differential package of the software to be upgraded, it will perform differential upgrade on the software to be upgraded, save the differential package to the external memory, the software type in the external memory is consistent with the software type in the active partition, and the latest version of the software is restored based on the differential package and the current version of the software. Saving the differential package to the external memory can ensure that when restoring the latest version of the software, the software of the active partition and the inactive partition are different, and differential upgrade can be performed based on the current version of the software in the active partition.

[0054] S320: Determine an upgrade method for the software to be upgraded according to the activated partition and the software type of the software to be upgraded in the external memory.

[0055] The software type may include the current version software and the latest version software. The current version software is an older version software than the latest version software. The upgrade methods include 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 software to be upgraded, differential upgrade cannot be performed, and full upgrade can be performed.

[0056] S330: When the upgrade mode of the software to be upgraded is differential upgrade, the latest version of the software is generated in the external memory according to the differential package and the current version of the software.

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

[0058] The boot file contains the necessary information and instructions for starting the operating system, such as the file address of the storage software package. It is mainly responsible for loading the operating system, ensuring that the system can boot correctly, and determining the system partition.

[0059] When performing a differential upgrade, first copy the latest version of the software in the external storage to the inactive partition, then switch the partition pointed to by the boot file, complete the switch between the active partition and the inactive partition, and update the software type of the active partition to the latest version of the software to achieve a differential upgrade.

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

[0061] After the software to be upgraded is upgraded, the latest version of the software may not run normally, and its running status will affect the next software upgrade. To ensure that each software upgrade can proceed normally, the software type in the external storage and the active partition needs to be determined according to the running status of the latest version of the software. If the software type in the external storage and the active partition cannot accurately complete the software upgrade, the software type needs to be adjusted.

[0062] By adding an external memory outside the internal memory of the electronic controller to store the same version of software as the activated partition, the hardware cost is low. While ensuring that the differential upgrade process can be carried out seamlessly, it also ensures that the inactive partition can provide rollback protection for the active partition, thereby improving the user experience of remote upgrades.

[0063] As a feasible method, the upgrade method of the software to be upgraded is determined according to the software types of the software to be upgraded in the activated partition and the external memory, including:

[0064] When the software types of the software to be upgraded contained in the activation partition and the external memory are the same, determining that the upgrade mode of the software to be upgraded is differential upgrade;

[0065] When the software types of the software to be upgraded contained in the active partition and the external memory are different, it is determined that the upgrade mode of the software to be upgraded is full upgrade.

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

[0067] When the software types of the software to be upgraded contained in the activation partition and the external memory are different, it indicates that there is no old version of the software matching the differential package in the external memory, and differential upgrade cannot be performed, and the upgrade method of the software to be upgraded is determined to be a full upgrade. By judging whether the software types of the software to be upgraded contained in the activation partition and the external memory are the same, the upgrade method of the software to be upgraded is determined, which can ensure that the software types of the software to be upgraded contained in the activation partition and the external memory are the same when the next differential upgrade is performed. Especially when performing a software version rollback, the software versions of the external memory and the activation partition must be synchronized, and this process takes time. In order to avoid incomplete synchronization before the next differential upgrade, differential upgrade is performed only when the software versions of the external memory and the activation partition are the same.

[0068] As an achievable method, based on the boot file of the internal memory, the latest version of the software in the external memory is switched from the inactive partition to the active partition, including:

[0069] Copy the latest version of the software in the external storage to the inactive partition;

[0070] According to the boot file of the internal memory, the software types of the software to be upgraded in the inactive partition and the active partition are switched, so as to switch the latest version of the software in the external memory to the active partition.

[0071] Since the software running in the active partition can be stopped according to user needs, and the software not running in the inactive partition can be started according to user needs, the switching between the active partition and the inactive partition can be achieved through the corresponding boot file in the internal memory. In other words, the software that is stopped in the active partition can be divided into the inactive partition, and the software that is started in the inactive partition can be divided into the active partition.

[0072] The current version of the software in the differential package and the external memory is restored to the latest version of the software and the installation is completed. After the external memory is flashed, the latest version of the software is copied to the inactive partition. At this time, the latest version of the software is the software that is not running, and the current version of the software is the running software. According to the boot file of the internal memory, the software type of the software to be upgraded in the inactive partition and the active partition is switched to achieve software upgrade or rollback in the inactive partition and the active partition.

[0073] Specifically, according to the file address of the software in the boot file of the internal memory, the latest version of the software in the inactive partition is switched to the active partition, and the current version of the software in the active partition is switched to the inactive partition. After the electronic controller restarts, the software update is completed. After the rollback occurs, the electronic controller needs to copy the software of the active partition to the external memory to facilitate the next differential upgrade.

[0074] As an achievable method, the software types in the external storage and the active partition are determined according to the running status of the latest version of the software in the active partition, including:

[0075] If the latest version of the software running in the activated partition is abnormal, the software type in the activated partition and the external storage device will be restored from the latest version of the software to the current version of the software.

[0076] If the latest version of the software runs abnormally in the activated partition, it means that the software cannot be used as the old version for the next software upgrade. The software type in the activated partition and the external storage device will be restored from the latest version of the software to the current version of the software.

[0077] Specifically, the current version of the software in the inactive partition is rolled back with the latest version of the software in the active partition, so that the latest version of the software in the active partition is restored to the current version of the software, and the current version of the software in the active partition is synchronized to the external memory, so that the latest version of the software in the external memory is restored to the current version of the software. At this time, the software in the active partition and the external memory are the same version, which is convenient for the next differential upgrade, and the inactive partition is the previous version, which is convenient for software rollback.

[0078] As an achievable method, the software types in the external storage and the active partition are determined according to the running status of the latest version of the software in the active partition, including:

[0079] If the latest version of the software runs normally in the active partition, make sure that the software types in the external storage and the active partition are the latest version of the software.

[0080] If the latest version of the software runs normally in the activated partition, it indicates that this version of the software can be used as the old version of the software for the next software upgrade. The latest version of the software is retained in the external storage and the activated partition for the next differential upgrade.

[0081] It should be understood that although Figure 3 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in the application, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 3 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed 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 part of the sub-steps or stages of other steps.

[0085] The generating module 430 is used to generate the latest version of the software in the external memory according to the differential package and the current version of the software when the upgrade mode of the software to be upgraded is differential upgrade;

[0086] A switching module 440, for switching the latest version of the software in the external memory from the inactive partition to the active partition based on the boot file of the internal memory;

[0087] The determination module 420 is further used to determine the software types in the external memory and the active partition according to the running status of the latest version of the software in the active partition, so as to facilitate the next software upgrade.

[0088] As an achievable method, determination module 420 is specifically used to determine that the upgrade method of the software to be upgraded is a differential upgrade when the software types of the software to be upgraded contained in the activated partition and the external memory are the same; when the software types of the software to be upgraded contained in the activated partition and the external memory are different, determine that the upgrade method of the software to be upgraded is a full upgrade.

[0089] As an implementable method, the switching module 440 is specifically used to: copy the latest version of the software in the external memory to the inactive partition; according to the boot file of the internal memory, switch the software type of the software to be upgraded in the inactive partition and the active partition to switch the latest version of the software in the external memory to the active partition.

[0090] As an implementable manner, the switching module 440 is specifically used to: switch the latest version of software in the inactive partition to the active partition according to the boot file in the internal memory; switch the current version of software in the active partition to the inactive partition.

[0093] As an implementable manner, the determination module 420 is further specifically used to: if the activation partition runs the latest version of the software normally, determine that the software types in the external memory and the activation partition are both the latest version of the software.
