The network 104 may include various connection types, such as wired, wireless communication links, or optical fiber cables, etc.

[0056] The user can use the first terminal device 101, the second terminal device 102 or the third terminal device 103 to interact with the server 105 through the network 104 to receive or send messages, etc. Various communication client applications can be installed on the first terminal device 101, the second terminal device 102, and the third terminal device 103, such as web browser applications, shopping applications, search applications, instant messaging tools, email clients, social platform software, etc.

[0057] The first terminal device 101, the second terminal device 102, and the third terminal device 103 can be various electronic devices with display screens and supporting web browsing, including but not limited to smart phones, tablet computers, e-book readers, MP3 players (Moving Picture Experts Group Audio Layer III), MP4 (Moving Picture Experts Group Audio Layer IV) players, laptop computers, desktop computers, etc.

[0058] The server 105 may be a server that provides various services, for example, a background server that provides support for pages displayed on the first terminal device 101 , the second terminal device 102 , and the third terminal device 103 .

[0059] It should be noted that the vehicle-mounted virtual personal assistant resource update method provided in the embodiment of the present invention is generally executed by a server / terminal device, and accordingly, the vehicle-mounted virtual personal assistant resource update device is generally arranged in the server / terminal device. The embodiment of the present invention is based on the Unity3d engine to update the action resources and decisions of the vehicle-mounted virtual personal assistant. Through the update of action resources and decisions, the VPA action performance is made more diverse. The car on which the embodiment of the present invention relies has an intelligent cockpit system of the Android system, which relies on cloud services to provide action resources and decision storage. The innovation of the embodiment of the present invention is that the update process is inside the VPA software. The embodiment of the present invention mainly solves the purpose of modifying the VPA action performance and action decision by updating the VPA action resources and decisions during the VPA startup process.

[0060] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0061] Embodiment 1

[0062] Continue to refer Figure 2 , shows a flow chart of an embodiment of a method for updating resources of a vehicle-mounted virtual personal assistant of the present invention. The method for updating resources of a vehicle-mounted virtual personal assistant comprises the following steps:

[0063] Step S1, obtaining in-vehicle virtual personal assistant resources.

[0064] In this embodiment, the vehicle-mounted virtual personal assistant resource update method is executed on the electronic device (eg Figure 1The server / terminal device shown in the figure can receive the in-vehicle virtual personal assistant resource update request through a wired connection or a wireless connection. It should be noted that the above wireless connection method may include but is not limited to 3G / 4G / 5G connection, WiFi connection, Bluetooth connection, WiMAXX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future.

[0065] The Unity3d engine is a real-time 3D development platform, mainly used to develop VPA action displays. Figure 3 Schematic diagram of the action controller used in the vehicle-mounted virtual personal assistant resource update method of the present invention. The action controller refers to a file created by the Unity3d engine. Figure 3 As shown, the square bar ① indicates that the action contains the reference of the action file, that is to say, the action controller file contains the reference relationship of these action files, and the corresponding actions can be found through the action controller; the pointing arrow ② indicates the transition and condition between actions, which means that, for example, when the current VPA is playing leisure actions, when the conditional instruction to play dance actions is reached, the difference calculation will be automatically performed during the switching to dance actions, so that the transition of VPA from leisure actions to dance actions is smoother. For example, 1000000, 1000001, 1000002, 1000003, etc. respectively represent leisure actions, dance actions, reading actions, listening to music actions, etc. The embodiment of the present invention is to handle the process of updating the VPA action controller file and the action files referenced by the square bar ① during the VPA startup process.

[0066] In this embodiment, step S1 may further include the following steps:

[0067] S11. Obtain VPA action files through 3DMax and Maya.

[0068] The VPA action file can be designed by the designer through 3DMax, Maya and other software, and the VPA action file can be obtained through 3DMax and Maya.

[0069] S12: Obtain a decision profile related to the VPA action.

[0070] The decision profile may be a decision for switching between various actions designed by the designer, that is, logic and conditions for action switching.

[0071] Step S2: Packaging the acquired in-vehicle virtual personal assistant resources.

[0072] In this embodiment, step S2 may further include the following steps:

[0073] S21. Label the acquired in-vehicle virtual personal assistant resources according to preset labeling rules.

[0074] Tagging refers to tagging files in a folder. You can tag files in a folder randomly, or you can customize tags for specific files in a folder. The packaging tool uses these tags to package files in order to filter out the files to be packaged during the packaging process.

[0075] The preset marking rule refers to the pre-set rules for labeling files in the folder. For example, if it is an action file, the action file will be labeled, and if it is a material file or an image file, it will be directly filtered out without labeling.

[0076] S22. Pack the labeled in-vehicle virtual personal assistant resources into a resource file.

[0077] Unity3d's AssetBundle is used to package resources. AssetBundle is an archive file that contains platform-specific non-code resources (such as models, textures, prefabs, audio clips, and even entire scenes) that can be loaded by Unity at runtime. AssetBundles can represent dependencies between each other; for example, a material in one AssetBundle can reference a texture in another AssetBundle. To improve the efficiency of transmission over the network, you can choose to compress the AssetBundle using a built-in algorithm based on the use case requirements (LZMA and LZ4). AssetBundles can be used for downloadable content (DLC), reduce the initial installation size, load resources optimized for the end-user platform, and reduce runtime memory pressure.

[0078] S23, encrypting the packaged resource files.

[0079] The packaged resource files can be encrypted using AES. The AES encryption process involves four operations, namely byte substitution, row shift, column confusion, and round key addition. The decryption process is the corresponding inverse operation. Since each operation is reversible, the plaintext can be restored by decrypting in the reverse order. The key for each round of encryption and decryption is expanded from the initial key.

[0080] S24, calculating the MD5 value of the encrypted resource file, and creating an MD5 file list corresponding to the file name and the MD5 value.

[0081] In order to quickly compare the differences between files, calculate the MD5 value of the encrypted resource file. Create an MD5 file list with the file name and MD5 value corresponding to it for use when the resource update system is updated.

[0082] Figure 4 FIG. 1 is a flowchart of a specific implementation of step S2 in the vehicle-mounted virtual personal assistant resource update method of the present invention. Figure 4 As shown, the process of packaging the acquired in-vehicle virtual personal assistant resources includes the following steps:

[0083] S201: Label the VPA action file and the decision configuration file.

[0084] S202: Determine whether there are old packaged resources. If yes, proceed to step S203; otherwise, proceed to step S204.

[0085] After packaging, the files will be stored in a specified folder. You only need to determine whether there are files in this folder. If there are files, they are old files left over from the last packaging and need to be deleted.

[0086] S203, deleting old packaged resources.

[0087] You can delete old packaged resources through the file deletion command File.Delete.

[0088] S204: Pack the files marked with the tag.

[0089] S205, encrypting the packaged file with AES.

[0090] AES is the Advanced Encryption Standard, also known as Rijndael encryption in cryptography. It is a block encryption standard adopted by the US federal government. This standard is used to replace the original DES and has been widely used around the world. At the same time, AES has become one of the most popular algorithms in symmetric key encryption. AES supports three key lengths: 128 bits, 192 bits, and 256 bits.

[0091] S206, calculating the MD5 value of the encrypted file, and creating an MD5 file list corresponding to the file name and the MD5 value.

[0092] Use WriteLine in StreamWriter to write the MD5 value corresponding to the file name into the Txt document file in the format of: file name | MD5 value.

[0093] Step S3: updating the packaged in-vehicle virtual personal assistant resources.

[0094] In this embodiment, step S3 may further include the following steps:

[0095] S31. Check the version number of the in-vehicle virtual personal assistant resource to determine whether the in-vehicle virtual personal assistant resource needs to be updated.

[0096] First, download the resource version number file. The version number file stores the maximum version number corresponding to each major version. Check these version number information with the version number in the software to see if the in-vehicle virtual personal assistant resources need to be updated. The resource version number file is created by the designer to record the version information of the VPA. For example, the first version can be 20230626001, and the next version will increase by one. If the version number in the version information of the VPA on the vehicle side is 20230626005, and the maximum version number in the version number file on the server already exists as 20230626006, it means that the resource file in the server is newer than the resource file in the VPA software, so it needs to be updated. Otherwise, it does not need to be updated, and the maximum version number in the server needs to be edited.

[0097] S32: If it is determined that the in-vehicle virtual personal assistant resources need to be updated, a list of updated files is created by comparison based on the MD5 file list.

[0098] First, determine whether there is an MD5 file list locally. If there is no file list locally, copy the MD5 file list and corresponding resource files in the software package to the local computer. If there is, proceed to the next step, download the latest MD5 file list from the cloud server, and then calculate the MD5 value of the server MD5 file list file just downloaded and compare it with the MD5 value of the file in the local MD5 file list. If the comparison results are consistent, it means that the resources in the cloud server and the local resources are consistent and do not need to be updated. If they are inconsistent, an update is required. At this time, compare the MD5 values ​​of the files in the MD5 file list downloaded from the cloud server with the MD5 values ​​of the files in the local MD5 file list, and check out the inconsistent files to form the updated file list.

[0099] S33. Download the in-vehicle virtual personal assistant resources that need to be updated according to the update file list.

[0100] The update file list obtained in step S32 is updated through the UnityWebRequest system. Figure 5 Schematic diagram of the UnityWebRequest architecture used in the vehicle-mounted virtual personal assistant resource update method of the present invention. Figure 5As shown, UnityWebRequest is a system for processing HTTP requests provided by Unity3d. UnityWebRequest is a system module provided by Unity3d. The UnityWebRequest ecosystem decomposes HTTP transactions into three different operations: first, providing data to the server; second, receiving data from the server, and third, HTTP flow control. The UploadHandler object handles the transmission of data to the server. The DownloadHandler object handles the reception, buffering, and post-processing of data received from the server. The UnityWebRequest object manages the other two objects and also handles HTTP flow control.

[0101] Figure 6 FIG. 1 is a flowchart of a specific implementation of step S3 in the vehicle-mounted virtual personal assistant resource update method of the present invention. Figure 6 As shown, the process of updating the packaged in-vehicle virtual personal assistant resources includes the following steps:

[0102] S301, determine whether there is a local MD5 value file list file, if not, go to step S302, if yes, go to step S303.

[0103] S302: Copy the MD5 file list file in the VPA software package and the files recorded in the MD5 file list to a local folder.

[0104] S303: Check the version number.

[0105] First, determine the first version, for example, it can be 20230626001, and the version numbers of subsequent versions are incremented by one. If the version number in the version information of the VPA on the vehicle side is 20230626005, and the maximum version number in the version number file on the server already exists as 20230626006, it means that the resource file in the server is newer than the resource file in the VPA software, so it needs to be updated. Otherwise, it does not need to be updated. The editing of the maximum version number in the server requires manual editing.

[0106] S304: Determine whether the file needs to be updated, if yes, proceed to step S305.

[0107] S305 , compare the MD5 values ​​of the local file and the remote MD5 file list file to obtain an updated file list.

[0108] The VPA software will have a local file MD5 file list file inside, and the server will also have an MD5 file list file. The MD5 file list file stores a large number of txt text files in the format of [file name | MD5 value]. The MD5 value is equivalent to the file ID, and its value is unique. By comparing the MD5 values ​​of the two text files to see if they are consistent, you can determine whether they need to be updated. If they are consistent, it means that the two text files are the same, and the contents are also the same, so there is no content to be updated. If they are inconsistent, there may be content that needs to be updated. At this time, the following steps are required to determine which specific content to update.

[0109] S306: Update and replace the file by updating the file list.

[0110] Updating files is done through UnityWebRequest, and the file is saved through File.WriteAllBytes. If the file exists, it will be overwritten.

[0111] Step S4: Load the updated in-vehicle virtual personal assistant resources.

[0112] It should be noted that updating refers to downloading server resource files to the local hard disk, and loading refers to loading resources from the local hard disk into the memory to replace the old in-vehicle virtual personal assistant resources.

[0113] In this embodiment, step S4 may further include the steps of:

[0114] S41. Combining the file names and local storage paths in the local MD5 file list into a file loading address list.

[0115] The absolute path of the resource storage obtained through Application.persistentDataPath and the file name recorded in the MD5 file list can be combined to get the absolute path of the specific file.

[0116] S42. When loading the VPA action controller file, a list of all dependent action file names is obtained according to the reference relationship.

[0117] The VPA action controller file is created by the Unity3d engine. The VPA action controller file contains references to all actions. By loading the VPA action controller file, you can find the names of all action files, and then use the MD5 file list to get the loading address and load the action file.

[0118] S43: Load the in-vehicle virtual personal assistant resources according to the action file name list and the file loading address list.

[0119] The addresses of all resources are known by combining the addresses in step S41, and then loaded through AssetBundle.LoadFromFile. AssetBundle is a Unity3d resource management tool.

[0120] Figure 7 FIG. 4 is a flowchart of a specific implementation of step S4 in the vehicle-mounted virtual personal assistant resource update method of the present invention. Figure 7 As shown, the process of loading the updated in-vehicle virtual personal assistant resource to replace the old in-vehicle virtual personal assistant resource includes the following steps:

[0121] S401. Synthesize a file loading address list according to the file names in the local MD5 file list and the local storage paths.

[0122] S402: Obtain a list of all action file names according to the reference relationship of the VPA action controller.

[0123] S403: Load the required files according to the action name list and the file loading address list.

[0124] S404, determine whether the loading is successful, if not, go to step S405, if yes, go to step S406.

[0125] Load via AssetBundle.LoadFromFile, AssetBundle.

[0126] LoadFromFile will record whether the loading is successful. AssetBundle is a Unity3d resource management tool.

[0127] S405, update the cloud service file (referring to the update file stored in the server. During the update process, a file may not be updated successfully due to some reasons. At this time, the loading will definitely prompt that the loading is unsuccessful. At this time, you can enter the update step to update the file locally) to the local.

[0128] It should be noted that cloud service files refer to update files stored in the server. During the update process, a file may not be updated successfully due to some reasons. At this time, the loading will definitely prompt that the loading failed. At this time, you can enter the update step to update the file locally.

[0129] S406: It is indicated that the file has been updated successfully.

[0130] In order to avoid the failure of loading the in-vehicle virtual personal assistant resources due to network failure or human factors, the loading can be attempted again after a loading failure. In some optional implementations of this embodiment, after step S43, the electronic device may further perform the following steps:

[0131] S5. Determine whether the loading of the in-vehicle virtual personal assistant resource is successful.

[0132] S6. If loading of the in-vehicle virtual personal assistant resource fails, attempt to reload it with a preset number of repeated loading times.

[0133] The preset number of repeated loading times can be set according to the current network busyness. If the network environment is complex, due to the problem of transmission bandwidth, the preset number of repeated loading times can be set higher, such as 4 to 6 times. If the network environment is simple, the probability of a successful loading in one time is relatively high, and the preset number of repeated loading times can be set lower, such as 1 to 3 times.

[0134] S7. If the reloading fails after reaching the preset number of repeated loading times, a loading failure message is prompted.

[0135] It should be emphasized that in order to further ensure the privacy and security of the above-mentioned in-vehicle virtual personal assistant resource information, the above-mentioned in-vehicle virtual personal assistant resource information can also be stored in a node of a blockchain.

[0136] The blockchain referred to in this invention is a new application mode of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. Blockchain is essentially a decentralized database, a string of data blocks generated by cryptographic methods. Each data block contains a batch of network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. Blockchain can include the underlying blockchain platform, platform product service layer, and application service layer.

[0137] The beneficial effects of implementing this embodiment are as follows: by first acquiring the vehicle-mounted virtual personal assistant resources, then packaging the acquired vehicle-mounted virtual personal assistant resources, then updating the packaged vehicle-mounted virtual personal assistant resources, and finally loading the updated vehicle-mounted virtual personal assistant resources to replace the old vehicle-mounted virtual personal assistant resources; the vehicle-mounted virtual personal assistant resources can be updated in a targeted manner to achieve the purpose of modifying the VPA action performance and action decision-making, which can provide users with a multi-dimensional and three-dimensional experience and adapt to the diversity of VPA changes; it can achieve a seamless upgrade, effectively improve user experience and satisfaction, and effectively reduce after-sales maintenance costs.

[0138] The present invention can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronic devices, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present invention can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform specific tasks or implement specific abstract data types.
