[0023] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] The present application provides a remote upgrade device for an intelligent networked vehicle, which includes: an upgrade service platform 1, an intelligent vehicle networking module 2, and an intelligent vehicle module to be upgraded 3.

[0025] The upgrade service platform 1 communicates with the smart car networking module 2 via a local area network; the upgrade service platform 1 is used to configure upgrade packages, select smart cars to be upgraded, and prompt upgrade status.

[0026] The smart car networking module 2 and the smart car upgrade module 3 are arranged on the smart car to be upgraded.

[0027] The smart car networking module 2 serves as an external communication interface of the smart car, receives the upgrade package, and sends the upgrade package to the smart car module to be upgraded 3.

[0028] The smart car upgrade module 3 is used to execute the upgrade instructions according to the upgrade package and feedback the upgrade results; during the upgrade process, the smart connected car remote upgrade device supports differential upgrade, breakpoint resumption and software rollback after upgrade failure.

[0029] In an exemplary embodiment, the upgrade service platform 1 specifically includes:

[0030] The first judgment unit is used to judge whether the smart car to be upgraded needs to be upgraded according to the current software version of the smart car to be upgraded corresponding to the upgrade package and the version information in the software library.

[0031] The difference calculation unit is used to perform a difference calculation between the upgrade package and the original version upgrade package corresponding to the current software version to generate a difference upgrade package.

[0032] The block division unit is used to divide the differential upgrade package into blocks.

[0033] The second judgment unit is used to parse the unreceived upgrade package information sent by the intelligent vehicle networking module 2 to determine whether breakpoint resumption is required.

[0034] The breakpoint resume unit is used to calculate the transmission breakpoint, encrypt the remaining differential upgrade package of the block transmission, and send it to the intelligent vehicle networking module 2.

[0035] The differential upgrade package sending module is used to encrypt the differential upgrade package and send it completely to the smart car networking module 2.

[0036] A visual interactive interface is used to display upgrade information; the upgrade information includes selecting the drone to be upgraded, selecting the upgrade package, the upgrade status, and the upgrade result information.

[0037] In an exemplary embodiment, the difference calculation unit specifically includes:

[0038] The comparison subunit is used to decompress the upgrade package, compare the upgrade package with the original version upgrade package one by one, and determine whether the files are consistent; wherein the files are the upgrade package and the original version upgrade package.

[0039] The first difference patch generating subunit is used for, when the files are inconsistent and the files are text files, performing process difference processing on the upgrade package and the original version upgrade package by a diff difference method to generate a difference patch.

[0040] The second difference patch generating subunit is used for converting the binary file into ASCII encoding representation using the binascii module in the Python standard library when the files are inconsistent and the files are binary files, and then performing process difference processing on the ASCII encoding representation through the diff difference method to generate a difference patch.

[0041] The differential software package generating subunit is used to generate a differential software package according to one or more differential patches.

[0042] In an exemplary embodiment, the intelligent vehicle networking module 2 specifically includes:

[0043] The checking unit is used to check whether there is an unaccepted upgrade package according to the upgrade instruction, and if so, send information about unaccepted upgrade package to the upgrade service platform 1.

[0044] A decryption unit is used to download and decrypt the differential upgrade package.

[0045] The verification unit is used to perform integrity verification on the upgrade package.

[0046] The reporting unit is used to report the success or failure information of the upgrade package download to the upgrade service platform 1.

[0047] The parsing unit is used to parse the upgrade package and send the upgrade package to the smart car upgrade module 3.

[0048] The sending unit is used to send all reception and upgrade result information to the upgrade service platform 1.

[0049] In an exemplary embodiment, the smart car upgrade module 3 specifically includes:

[0050] The verification unit is used to perform integrity verification on the upgrade package.

[0051] The reception failure information sending unit is used to send the reception failure information to the intelligent vehicle networking module 2.

[0052] The upgrade attempt unit is used to attempt an upgrade according to the upgrade package and determine whether the upgrade is successful.

[0053] Rollback unit, used to roll back to the previous software version.

[0054] The sending unit is used to send all receiving and upgrading result information to the intelligent vehicle networking module 2.

[0055] Online upgrades for existing vehicles are mostly upgrades of released versions, which can basically run directly without the need for a failure rollback function. However, there are often many problems with the software in the testing phase, so designing a failure rollback function can effectively improve testing efficiency.

[0056] The execution steps of each module in the actual application of this application are as follows:

[0057] The power supply system of the smart car to be upgraded is started to enable the smart car networking module 2 and the smart car to-be-upgraded module 3 of the smart car to be upgraded to enter a working state.

[0058] The power supply system of the upgrade service platform 1 is started to put the upgrade service platform 1 into working state.

[0059] The upgrade service platform 1 has a software management function, and the upgrade package can be added to the software library of the upgrade service platform 1 by selecting a local file, and the upgrade service platform 1 automatically identifies its corresponding software and version.

[0060] Start the visual interactive interface of the upgrade service platform 1.

[0061] If a new upgrade package is needed, select the upgrade package in the interactive interface to update the upgrade package to the software library of the upgrade service platform 1.

[0062] Select the smart car to be upgraded, and control the upgrade service platform 1 to communicate with the smart car networking module 2.

[0063] An upgrade package is selected, and the upgrade package and upgrade instructions are sent to the smart car networking module 2 through the upgrade service platform 1.

[0064] After receiving the upgrade package information, the smart car networking module 2 sends the current software version of the smart car corresponding to the upgrade package to the upgrade service platform 1.

[0065] The upgrade service platform 1 compares the software versions based on the current software version of the smart car and the version information in the software library to determine whether an upgrade is required.

[0066] If so, the upgrade service platform 1 performs differential calculation on the upgrade package and the software package corresponding to the current software version of the smart car to generate a differential upgrade package. In the differential calculation, the upgrade package is first completely decompressed locally, and it is compared one by one with the original version upgrade package. If the files are consistent, there is no need to transfer them; if the files are inconsistent and the files are text files, such as py, sh, txt and other file formats, they are differentiated by the diff differential method. Diff is a file-level comparison tool that can find the differences between the file contents of two versions and generate differential patches; if the files are inconsistent and the files are binary files, the binascii module in the python standard library is used to convert the binary files into ASCII encoding representation, and then diff is used to compare and generate differential patches. Finally, a differential upgrade package consisting of multiple differential patches is generated.

[0067] If not, the visual interactive interface will prompt that no upgrade is required.

[0068] After receiving the upgrade instruction, the intelligent vehicle networking module 2 will also check whether there is a corresponding upgrade package that has not been received and send information that the upgrade package has not been received to the upgrade service platform 1. If not, it will send information that there is no upgrade package.

[0069] The upgrade service platform 1 analyzes the information of the unreceived upgrade package to determine whether it needs to be resumed. The judgment process is as follows: the unreceived upgrade package information includes the file name and the current size. The upgrade service platform 1 compares the size with the size of the complete upgrade package. If the size is the same, no transmission is required; if it is smaller than the complete upgrade package, it needs to be resumed.

[0070] If yes, the upgrade service platform 1 calculates the transmission breakpoint, and encrypts the remaining differential upgrade package for block transmission and sends it to the intelligent vehicle networking module 2. Furthermore, the files are transmitted in blocks, but the breakpoint is not necessarily after a complete transmission block, so it is necessary to calculate the end position of the last complete transmission block according to the file size and the transmission block size, and continue to transmit backward from this position.

[0071] If not, the upgrade service platform 1 encrypts the complete differential upgrade package and sends it to the intelligent vehicle networking module 2. Furthermore, all upgrades should transmit differential upgrade packages. If breakpoint resuming is required, the remaining differential upgrade packages are transmitted. If breakpoint resuming is not required and complete transmission is required, the complete differential upgrade package is transmitted.

[0072] The intelligent vehicle networking module 2 downloads the remaining differential upgrade package or the complete differential upgrade package, decrypts it and stores it in the intelligent vehicle networking module 2.

[0073] The intelligent car networking module 2 performs an integrity check on the upgrade package to determine whether the upgrade package is complete. The verification process is as follows: When the differential upgrade package is transmitted, an md5 verification file will be attached. The intelligent car networking module 2 only needs to perform md5 calculation on the received differential upgrade package and compare it with the verification file. If they are the same, the upgrade package is complete. If they are different, the upgrade package is damaged.

[0074] If not, the intelligent vehicle networking module 2 reports the upgrade package download failure information to the upgrade service platform 1.

[0075] If so, the smart car networking module 2 parses the upgrade package information to obtain the smart car to be upgraded module 3 to be upgraded. Further, the upgrade package should contain relevant information of the smart car to be upgraded module 3 to be upgraded, mainly including the address (IP) and update path of the smart car to be upgraded module 3, and the smart car networking module 2 automatically parses the information.

[0076] The intelligent vehicle networking module 2 is connected and communicated with the intelligent vehicle to-be-upgraded module 3 .

[0077] The intelligent vehicle networking module 2 sends an upgrade package to the intelligent vehicle module to be upgraded 3 .

[0078] After receiving the upgrade package, the smart car upgrade module 3 performs an upgrade package integrity check to determine whether the upgrade package is complete.

[0079] If not, a reception failure message is sent to the smart car networking module 2.

[0080] The smart car upgrade module 3 attempts to upgrade the corresponding software and determines whether the upgrade is successful.

[0081] If not, roll back the corresponding software to the previous version.

[0082] The smart car to-be-upgraded module 3 sends all the receiving and upgrading result information to the smart car networking module 2 .

[0083] The intelligent vehicle networking module 2 sends all reception and upgrade result information to the upgrade service platform 1 .

[0084] Based on all the received and upgraded result information, the upgrade service platform 1 analyzes the upgrade status and displays it on a visual interactive interface.

[0085] The embodiment of the present application provides a remote upgrade method for an intelligent network-connected vehicle, which is executed by a computer device, and can be executed by a computer device such as a terminal or a server alone, or can be executed by a terminal and a server together. In the embodiment of the present application, Figure 2 As shown, the method includes the following steps.

[0086] S201: Communicate with the smart car networking module 2 through the local area network via the upgrade service platform 1; the upgrade service platform 1 is used to configure the upgrade package, select the smart car to be upgraded, and prompt the upgrade status.

[0087] S202: Using the smart car networking module 2 as an external communication interface of the smart car, receiving the upgrade package, and sending the upgrade package to the smart car module to be upgraded 3; the smart car networking module 2 and the smart car module to be upgraded 3 are arranged on the smart car to be upgraded.

[0088] S203: Execute the upgrade command according to the upgrade package through the smart car upgrade module 3, and feedback the upgrade result; during the upgrade process, the smart connected car remote upgrade device supports differential upgrade, breakpoint resumption and software rollback after upgrade failure.

[0089] In an exemplary embodiment, the upgrade process of the differential upgrade specifically includes:

[0090] Decompress the upgrade package, and compare the upgrade package with the original version upgrade package one by one to determine whether the files are consistent; wherein the files are the upgrade package and the original version upgrade package.

[0091] When the files are inconsistent and the files are text files, the upgrade package and the original version upgrade package are differentially processed by a diff difference method to generate a differential patch.

[0092] When the files are inconsistent and the files are binary files, the binascii module in the Python standard library is used to convert the binary files into ASCII encoding representation, and then the ASCII encoding representation is differentially processed by the diff difference method to generate a difference patch.

[0093] A differential software package is generated based on one or more differential patches.

[0094] Advantage 1: It does not rely on cloud service platforms and is simple and fast to set up.

[0095] The existing online upgrade solutions for commercial vehicles generally require a 4G / 5G module on the vehicle, and the manufacturer builds a cloud server, and the two communicate to complete the online upgrade. This application is equivalent to a lightweight online upgrade solution, which only requires the module to be able to connect to the local area network (the smart car module to be upgraded is generally connected to the smart car networking module through the local area network, and the smart car networking module only needs to be connected to an Ethernet cable or a wireless network card), and the upgrade service platform module can be a laptop computer, which is equivalent to the role of a cloud server. The main advantage of the online upgrade method of this application is that it is simple to deploy, which simplifies the purchase and development costs of 4G / 5G modules and cloud service platforms. At the same time, it is basically implemented using the python built-in library, and the environment is quickly built during deployment.

[0096] Advantage 2: Strong portability and easy layout.

[0097] This application has low requirements for equipment and is easy to deploy on different types of smart cars. The upgrade service platform module supports both Windows and Linux systems. The smart car networking module and the smart car upgrade module only need a local area network interface. Therefore, this application has strong portability and is suitable for wide application in smart cars in special scenarios.

[0098] Advantage 3: The upgrade method has high redundancy.

[0099] This application supports breakpoint resuming and version rollback after upgrade failure during the upgrade process. Breakpoint resuming can effectively solve the communication interruption problem that may exist during the upgrade package transmission process; version rollback after upgrade failure plays an important role in the software testing stage, which can not only avoid software errors causing problems in the whole vehicle, but also simplify the software testing process.
