Description

Technical Field

[0001] The embodiments of the present invention relate to the field of chip technology, and specifically to an OTA upgrade method, system, device, and storage medium for a controller. Background Art

[0002] With the continuous development of computer communication technology and semiconductor technology, various existing electronic devices are becoming more and more complex. These electronic devices often integrate multiple chips, and generally require firmware upgrades to fix problems and add new functions. In related technologies, over-the-air technology (OTA) is usually used to upgrade firmware. OTA is a method of transmitting and upgrading firmware through an air wireless network, that is, OTA is a remote upgrade method. Specifically, using OTA to remotely upgrade the chip on the device can refer to downloading the upgraded firmware from the server through the communication module and transmitting the upgraded firmware to the chip to complete the chip upgrade process.

[0003] In the existing technology, the OTA upgrade method for the on-board computer (Electronic Control Unit, abbreviated as ECU) is mainly divided into two methods. Method 1: For ECUs without a file system, the OTA server transmits the upgrade package directly to the ECU without compression. The ECU flashes one frame for each frame transmitted. Method 2: For ECUs with a file system, when creating the OTA package, all files are packaged and compressed into a single package, such as a zip file. The OTA server needs to pass the entire compressed package to the ECU before the ECU can start decompressing and installing it.

[0004] Currently, ECUs usually contain multiple control chips, such as MCUs and SoCs. If the download is not compressed, the download package will be extremely large, and multiple chips in the ECU cannot be installed in parallel. If a compressed package is used for download, the entire upgrade package must be downloaded before decompression and upgrading can begin. Installation cannot be performed while downloading, resulting in low overall installation efficiency. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present invention provides an OTA upgrade method, system, device and storage medium for a controller, which is used to solve the problem in the prior art that when upgrading the control chip, the entire upgrade package needs to be downloaded before decompression and upgrading can begin, and installation cannot be performed while downloading, resulting in low overall installation efficiency.

DETAILED DESCRIPTION

[0024] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0025] Example 1: Figure 1 FIG1 shows a flow chart of a first embodiment of an OTA upgrade method for a controller of the present invention, which is executed by the controller. Figure 1 As shown, the method includes the following steps: Step 110: Download a continuous data stream, wherein the data stream includes a plurality of sequentially arranged upgrade data packets and at least one header file information describing each upgrade data packet.

[0026] The above-mentioned data stream can be continuous data or a large file package. During the download process, the data is downloaded in a preset data order. The package format can be uncompressed. During the download process, parsing and data separation can be performed using a preset protocol. This transmission in the form of a continuous data stream can not only improve transmission efficiency, but also avoid the problem of waiting for the entire large compressed package to be downloaded. The downloaded continuous data stream includes multiple upgrade data packets and at least one header file information corresponding to the multiple upgrade data packets. The header file information describes the data information within the multiple upgrade data packets. During the data stream download process, the system reads the header file information downloaded in real time. Through the header file information, it can be obtained how many bytes in the data stream belong to the same upgrade data packet. For example, through the header file information, it can be determined how many bytes in the data stream belong to the first upgrade data packet and how many bytes belong to the second upgrade data packet.

[0027] The data stream may originate from a data source such as a server or a data storage terminal, and may be downloaded from the server or data storage terminal via a wired or wireless method.

[0028] Step 120: Read the header file information in the data stream, and separate the upgrade data packets from the data stream in sequence according to the header file information.

[0029] The process involves reading header information from a data stream and sequentially separating multiple upgrade data packets from the data stream, so that each upgrade data packet corresponds to a different upgrade object. For example, from a downloaded data stream, data information belonging to the same upgrade data packet is obtained using header information, and this data information corresponds to a single upgrade object.

[0030] It should be noted that based on the parsed header information, the system can accurately separate the individual update packets from the data stream. This process is dynamic, meaning that as the data stream continues to download, the system can begin separating and processing received packets without having to wait for the entire data stream to download.

[0031] Step 130: Establish a multi-thread task to perform an upgrade operation on the upgrade object corresponding to the currently separated upgrade data packet until all upgrade data packets in the data stream are completely separated.

[0032] The separated update packets perform the upgrade operation on the corresponding update objects until all update packets in the data stream are separated. This means that multiple update packets perform the upgrade operation on multiple update objects one by one. For example, after the first update packet is separated from the data stream and downloaded, a multi-threaded task is started to install the update packet, performing the upgrade operation on the update object, while simultaneously downloading the second update packet.

[0033] As you can see, once an update package has been successfully separated and downloaded, the system immediately starts a new thread to handle the update operation for that package. This multi-threaded approach allows multiple update operations to proceed in parallel, fully utilizing the multi-core capabilities of modern processors and improving update efficiency.

[0034] The above method downloads a continuous data stream, which includes multiple upgrade data packets arranged in sequence and at least one header file information describing each upgrade data packet. During the process of downloading the data stream, the multiple upgrade data packets are separated in real time by reading the header file information. Once an upgrade data packet is successfully separated and downloaded, the system immediately starts a new thread to process the upgrade operation of the upgrade data packet, and continues to separate another upgrade data packet. In this way, the download and installation of the upgrade data packets are carried out simultaneously, thereby improving the upgrade efficiency.

[0035] In some embodiments, each data packet number corresponds to a header file information; the header file information is arranged before the corresponding upgrade data packet. Figure 2 As shown, for example, the downloaded data stream contains three upgrade data packets, including upgrade data packet 1, upgrade data packet 2, and upgrade data packet 3. The arrangement order is: header file information 1, upgrade data packet 1, header file information 2, upgrade data packet 2, header file information 3, and upgrade data packet 3.

[0036] In this embodiment, by configuring independent header information for each update packet, the boundaries of each update packet can be accurately identified and located, facilitating subsequent separation operations. Placing the header information before the corresponding update packet enables the system to pre-read the header information and obtain key information about the update packet, preparing for subsequent separation and processing. This allows for efficient identification, location, and separation of multiple update packets within a data stream.

[0037] It should be noted that this arrangement can be implemented in a variety of ways. For example, the header information can be placed immediately before its corresponding upgrade data packet. In other embodiments, all header information can be placed at the beginning of the data stream and arranged in the order of the upgrade data packets. Preferably, the header information is placed immediately before its corresponding upgrade data packet to facilitate subsequent expansion of the data stream.

[0038] In some embodiments, the arrangement order of the multiple upgrade data packages is determined by the installation time of the upgrade data packages, and the priority of the arrangement order is positively correlated with the installation time.

[0039] In this embodiment, the installation duration of an upgrade data packet determines its placement within multiple upgrade data packets, and the priority of placement is positively correlated with the installation duration. For example, data packets with longer installation durations are placed first, allowing longer-running upgrade tasks to begin first, thereby improving parallel processing efficiency. This sorting method maximizes parallel processing capabilities, reduces overall upgrade time, and improves OTA upgrade efficiency.

[0040] In some embodiments, the upgrade data package includes a first data package arranged in front and a second data package arranged in the back, and the installation time of the first data package is longer than that of the second data package.

[0041] In this embodiment, the data packet with a longer installation time, i.e., the first data packet, is placed in front, and the data packet with a shorter installation time, i.e., the second data packet, is placed in the back. This sorting method helps to solve the impact of differences in the installation time of upgrade data packets on the OTA upgrade efficiency.

[0042] It should be noted that the above-mentioned first data packet and second data packet do not limit the number of data packets in the data stream. They can be understood as at least two upgrade data packets contained in the data stream, which can be arranged according to the above-mentioned rules, thereby effectively shortening the upgrade time.

[0043] As you can see, because upgrade packages that require longer installation times are queued at the front, multithreaded tasks can begin processing these complex upgrade packages earlier, while upgrade packages that require shorter installation times can be processed quickly later. This combination not only optimizes parallel processing efficiency but also improves overall resource utilization.

[0044] Please refer to Figure 3 , Figure 3 An example of an implementation process of an upgrade operation is given. The data stream contains multiple upgrade data packets, which upgrade different upgrade objects respectively. The download and installation are performed simultaneously through multi-threaded tasks. Specifically, during the download process, upgrade data packet 1, upgrade data packet 2, upgrade data packet 3, and upgrade data packet 4 are downloaded in sequence. Among them, the installation time of upgrade data packet 1 is relatively long. After the download of upgrade data packet 1 is completed, the controller establishes a new multi-threaded task 1 to perform an upgrade operation on upgrade data packet 1, and continues to download upgrade data packet 2 at the same time; after the download of upgrade data packet 2 is completed, the controller establishes a new multi-threaded task 2 to perform an upgrade operation on upgrade data packet 2, and continues to download upgrade data packet 3 at the same time; after the download of upgrade data packet 3 is completed, the controller establishes a new multi-threaded task 3 to perform an upgrade operation on upgrade data packet 3, and continues to download upgrade data packet 4 at the same time, until the upgrade operation is completed for all upgrade data packets.

[0045] This arrangement significantly improves upgrade efficiency. For example, if 1. System Upgrade Package 1 (estimated installation time: 10 minutes), 2. System Upgrade Package 2 (estimated installation time: 5 minutes), 3. System Upgrade Package 3 (estimated installation time: 3 minutes), and 4. System Upgrade Package 4 (estimated installation time: 2 minutes) are being installed simultaneously, the other three System Upgrade Packages 3 (a total of 10 minutes) can be processed in parallel. Assuming the system can handle all three tasks simultaneously, even including download time, the entire upgrade process can be completed in just over 10 minutes, rather than the 20 minutes required for a sequential installation plus the additional download time.

[0046] In some embodiments, the header file information includes upgrade duration information corresponding to the installation duration of the upgrade data package.

[0047] In this embodiment, by including the installation duration information for each upgrade data package in the header file information, the system can determine the estimated installation time for each upgrade data package before the upgrade begins. Using this information, the system can rationally arrange the processing order of each upgrade data package, for example, prioritizing packages with longer installation times. This improves overall upgrade efficiency, reduces idle time during the upgrade process, and makes the entire upgrade process more compact and efficient.

[0048] In some embodiments, the upgrade duration information is responsive to one or more of the data size, data type, upgrade object, and estimated duration data of the upgrade data packet.

[0049] In this embodiment, the upgrade duration of an upgrade data packet is determined based on one or more of the following: data size, data type, upgrade target, and estimated duration data. Specifically, the upgrade duration information can be determined based on one or more factors. By considering one or more of these factors, the system can more accurately estimate the time required for the upgrade. The advantage of this method lies in its flexibility and adaptability. Depending on the actual situation, the most relevant factors can be selected to estimate the upgrade time, thereby improving the accuracy of the sequential arrangement of multiple upgrade data packets.

[0050] For example, for an upgrade data package, the system will comprehensively consider its data size (such as 50MB) and data type (such as firmware upgrade). Based on this information, the system can estimate a more accurate upgrade duration (such as 15 minutes). This upgrade duration allows the system to better plan the arrangement order.

[0051] In some embodiments, the header file information includes data type information and data size information corresponding to the upgrade data packet.

[0052] In this embodiment, if Figure 4 As shown, the data type information represents the type of the upgrade data packet, and the data size information represents the size of the upgrade data packet. The system can obtain the data type and data size of the upgrade data packet through the header file information. In this way, the key data features can be obtained before the upgrade, thereby determining the arrangement order of multiple upgrade data packets.

[0053] Please combine Figure 5 , Figure 5 A flow chart of the sub-steps in step 120 of the OTA upgrade method for the controller of the present invention is shown.

[0054] In step 120, the header information in the data stream is read, and the upgrade data packet is separated from the data stream according to the header information, including the following sub-steps: Step 121: Read the data stream and identify the header file information in the data stream.

[0055] The starting position of each upgrade data packet is accurately located by identifying the header information in the data stream. The header information represents the key information of the upgrade data packet, such as the file size and file type of the upgrade data packet.

[0056] Step 122: Determine the data size of the upgrade data packet corresponding to the header file information according to the header file information.

[0057] The data size of the upgrade data packet corresponding to the identified header information is determined based on the identified header information. This step can be implemented in a variety of ways. For example, the header information may directly include a field for the data packet size, or the size may be calculated using a predefined algorithm based on other information in the header file. Accurately obtaining the data packet size determines the amount of data to be downloaded and separated.

[0058] Step 123: Calculate the download volume of the data stream starting from the header file information; when the download volume of the data stream is the same as the data size of the upgrade data packet; separate the data stream downloaded in the current stage to form an independent upgrade data packet.

[0059] Calculating the download volume of the data stream starting from the header file information can be achieved by monitoring the download progress of the data stream in real time. For example, a counter can be used to record the number of bytes downloaded, or the size change of the data stream buffer can be used to track the download progress. When the calculated download volume of the data stream is the same as the data size of the previously determined upgrade data packet, the data stream downloaded in the current stage is separated to form independent upgrade data packets. This step ensures that the separated data packets are complete, without data loss or redundant data.

[0060] In this embodiment, the header information in the data stream is identified, the data size of the upgrade data packet corresponding to the header information is obtained, the download volume of the data stream starting from the header information is calculated, and the download volume is compared with the data size of the upgrade data packet. If the download volume and the data size of the upgrade data packet are the same, the downloaded data stream is separated into independent upgrade data packets, thereby achieving the separation of the upgrade data packets. This method avoids the problem of having to download the entire data stream before parsing, thereby improving data processing efficiency.

[0061] Please combine Figure 6 , Figure 6 A flow chart of the sub-steps in step 130 of the OTA upgrade method for the controller of the present invention is shown.

[0062] In step 130, a multi-threaded task is established to perform an upgrade operation on the upgrade object corresponding to the currently separated upgrade data package, including the following sub-steps: Step 131: Create a new multi-threaded task; Step 132: Parse the currently separated upgrade data packet to determine the upgrade object; Step 133: performing an upgrade operation on the upgrade object according to the parsed upgrade data packet; Step 134: Determine whether the upgrade operation is completed. If the upgrade operation is completed, close the multi-threaded task.

[0063] The upgrade object is a chip and / or SOC.

[0064] In this embodiment, by establishing a multi-threaded task to parse and upgrade the currently separated upgrade data packets, multiple upgrade objects can be upgraded in parallel during the controller OTA upgrade process, thereby improving overall upgrade efficiency. The upgrade objects are upgraded based on the parsed upgrade data packets, ensuring the accuracy of the upgrade operation. The upgrade operation is then determined to be complete. If so, the corresponding thread task is closed, achieving efficient resource utilization.

[0065] For example, a thread is established to parse the first data packet and perform an upgrade operation on the first upgrade object, while continuing to download the second data packet. After the download is completed, another thread is created to parse the second data packet and perform an upgrade operation on the second upgrade object. After all upgrade objects have been upgraded, it is determined whether the upgrade operation is completed. If completed, the corresponding thread task is closed.

[0066] In some embodiments, establishing a multi-threaded task to perform an upgrade operation on the upgrade object corresponding to the currently separated upgrade data packet until all upgrade data packets in the data stream are completely separated further includes: Check whether the upgrade operation of all upgrade objects is completed; If the upgrade operation is completed for all upgrade objects, the upgrade flag is reported; otherwise, the flag indicating that the upgrade operation is not completed is reported.

[0067] For example, after each upgrade object is upgraded, the corresponding flag is set to the completed state, or the completion counter is incremented by 1. When the flags of all upgrade objects are in the completed state, or the completion counter is equal to the total number of upgrade objects, it can be determined that all upgrade operations are completed.

[0068] Example 2: like Figure 7 As shown, Figure 7 The schematic diagram of the control system of the present invention is a control system, comprising at least one functional chip module 10 and an upgrade module 20.

[0069] Among them, the function chip module 10 is used to execute preset functions; the upgrade module 20 is used to execute the steps of the above-mentioned controller OTA upgrade method to perform OTA upgrade operations on at least one function chip module 10.

[0070] In some embodiments, the functional chip module 10 may be used to perform assisted driving functions, assisted parking functions, cabin control functions, etc.

[0071] The upgrade module 20 is specifically configured to perform the following method steps: Downloading a continuous data stream, wherein the data stream includes a plurality of sequentially arranged upgrade data packets and at least one header file information describing each upgrade data packet; Read the header file information in the data stream, and separate the upgrade data packets from the data stream in sequence according to the header file information; A multi-threaded task is established to perform an upgrade operation on the upgrade object corresponding to the currently separated upgrade data packet until all upgrade data packets in the data stream are completely separated.

[0072] In some embodiments, the upgrade module 20 includes: a communication module 21 , a parsing module 22 and an execution module 23 .

[0073] Among them, the communication module 21 is used to download a continuous data stream, where the data stream can come from a remote OTA server; the parsing module 22 is used to read the header file information in the data stream and separate the upgrade data packet from the data stream according to the header file information; the execution module 23 is used to establish a multi-threaded task to perform an upgrade operation on the upgrade object corresponding to the currently separated upgrade data packet until all upgrade data packets in the data stream are separated.

[0074] It should be noted that the upgrade module 20 can be dedicated to upgrading the functional chip module or can also be used to upgrade the functional chip module. For example, the upgrade module can be the main control chip of the driving domain controller, which is also used to implement the intelligent assisted driving function when not performing the OTA upgrade operation of this application.

[0075] The above system downloads a continuous data stream, which includes multiple upgrade data packets arranged in sequence and at least one header file information describing each upgrade data packet. During the process of downloading the data stream, the system reads the header file information to achieve real-time separation of multiple upgrade data packets. Once an upgrade data packet is successfully separated and downloaded, the system immediately starts a new thread to process the upgrade operation of the upgrade data packet, and continues to separate another upgrade data packet. In this way, the download and installation of the upgrade data packet are carried out simultaneously, thereby improving the upgrade efficiency.

[0076] Example 3: Figure 8 The schematic diagram of the structure of an embodiment of the OTA upgrade device of the present invention is shown. The specific embodiment of the present invention does not limit the specific implementation of the OTA upgrade device.

[0077] like Figure 5 As shown, an OTA upgrade device may include: a processor (processor) 801, a communication interface (Communications Interface) 802, a memory (memory) 803, and a communication bus 804.

[0078] Processor 801, communication interface 802, and memory 803 communicate with each other via communication bus 804. Communication interface 802 is used to communicate with other devices, such as an OTA server or other server network elements. Processor 801 is used to execute program 810, which, when executed, implements the steps of the controller OTA upgrade method described above to perform an OTA upgrade operation on a preset upgrade target.

[0079] Specifically, the program 810 may include program code including computer-executable instructions.

[0080] Specifically, processor 801 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement embodiments of the present invention. The one or more processors included in the OTA upgrade device may be processors of the same type, such as one or more CPUs, or processors of different types, such as one or more CPUs and one or more ASICs.

[0081] The memory 803 is used to store the program 810. The memory 803 may include a high-speed RAM memory, or may also include a non-volatile memory (non-volatile memory), such as at least one disk memory.

[0082] Program 810 may be specifically called by processor 801 to enable the OTA upgrade device to perform the following operations: Downloading a continuous data stream, wherein the data stream includes a plurality of sequentially arranged upgrade data packets and at least one header file information describing each upgrade data packet; Read the header file information in the data stream, and separate the upgrade data packets from the data stream in sequence according to the header file information; A multi-threaded task is established to perform an upgrade operation on the upgrade object corresponding to the currently separated upgrade data packet until all upgrade data packets in the data stream are completely separated.

[0083] The above data flow is consistent with the data flow in Example 1. For details, please refer to the description in Example 1, which will not be repeated in this embodiment.

[0084] In an optional implementation, the program 810 is called by the processor 801 to enable the OTA upgrade device to execute the specific sub-steps of step 120 and step 130 in Example 1.

[0085] The above device downloads a continuous data stream, which includes multiple upgrade data packets arranged in sequence and at least one header file information describing each upgrade data packet. During the process of downloading the data stream, the multiple upgrade data packets are separated in real time by reading the header file information. Once an upgrade data packet is successfully separated and downloaded, the system immediately starts a new thread to process the upgrade operation of the upgrade data packet, and continues to separate another upgrade data packet. In this way, the download and installation of the upgrade data packet are carried out simultaneously, thereby improving the upgrade efficiency.

[0086] Example 4: An embodiment of the present invention provides a computer-readable storage medium storing at least one executable instruction. When the executable instruction runs on an OTA upgrade device, the OTA upgrade device executes the OTA upgrade method of the controller in any of the above method embodiments.

[0087] The executable instructions can be used to enable the OTA upgrade device to perform the following operations: Downloading a continuous data stream, wherein the data stream includes a plurality of sequentially arranged upgrade data packets and at least one header file information describing each upgrade data packet; Read the header file information in the data stream, and separate the upgrade data packets from the data stream in sequence according to the header file information; A multi-threaded task is established to perform an upgrade operation on the upgrade object corresponding to the currently separated upgrade data packet until all upgrade data packets in the data stream are completely separated.

[0088] By downloading a continuous data stream, which includes multiple upgrade data packets arranged in sequence and at least one header file information describing each upgrade data packet, the system can realize real-time separation of multiple upgrade data packets by reading the header file information during the data stream download process. Once an upgrade data packet is successfully separated and downloaded, the system immediately starts a new thread to process the upgrade operation of the upgrade data packet, and continues to separate another upgrade data packet. In this way, the download and installation of the upgrade data packet are realized simultaneously, thereby improving the upgrade efficiency.
