[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, 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.

[0040] Please refer to Figure 1, which is a schematic diagram of the framework of remote vehicle upgrade in the relevant technology. For batch upgrades of vehicles operating in an environment with poor mobile communication network quality, the success rate of batch upgrades is low because the connection between some vehicle terminals and the cloud platform may be unstable. At the same time, since batch upgrades require the cloud platform to upgrade each vehicle terminal separately, the efficiency is low; since the cloud platform needs to repeatedly transmit the same upgrade file to each vehicle terminal, the resource consumption is large; since batch upgrades require each vehicle terminal to maintain a connection with the cloud platform before upgrading, there are great limitations.

[0041] Based on this, an embodiment of the present application provides a vehicle remote upgrade method, which can be applied in an application environment as shown in Figure 2. Among them, the target vehicle end 102 communicates with the cloud platform 104 through the network. The data storage system can store the data that the cloud platform 104 needs to process. The data storage system can be integrated on the cloud platform 104 or other network servers. The target vehicle end 102 communicates with the associated non-target vehicle end 106 through a local area network communication link. Among them, the target vehicle end 102 and the non-target vehicle end 106 can be but are not limited to engineering vehicles such as new energy mining vehicles, high-speed machines, and excavators. The cloud platform 104 can be implemented based on an independent physical server, or it can be implemented based on a server cluster or distributed system composed of multiple physical servers or a cloud server that provides cloud computing services. The cloud platform 104 can be a cloud OTA platform.

[0042] In an exemplary embodiment, as shown in FIG3 , a vehicle remote upgrade method is provided, which is described by taking the method applied to the target vehicle terminal 102 in FIG2 as an example, and includes the following steps S202 to S206 . Among them:

[0043] Step S202, based on the mobile communication network, receiving the upgrade file sent by the cloud platform to the target vehicle end; the signal quality of the mobile communication network between the target vehicle end and the cloud platform is higher than the signal quality of the mobile communication network between the associated non-target vehicle end and the cloud platform.

[0044] Among them, the association relationship between multiple vehicle terminals can be determined by grouping multiple vehicle terminals based on the cloud platform, and the target vehicle terminal and the associated non-target vehicle terminal belong to the same group. In one possible implementation, the vehicle terminals used to operate in the same operating area can be divided into the same group. The target vehicle terminal can be the vehicle terminal with the best quality of signal transmission between the cloud platform and the same group, or the target vehicle terminal can also be the vehicle terminal with the quality of signal transmission between the cloud platform and the same group higher than the preset signal quality threshold. It can be understood that the number of target vehicle terminals in the same group can be one or more.

[0045] Exemplarily, the cloud platform can compare the signal quality of the mobile communication network between multiple vehicle terminals, determine the target vehicle terminal with better signal quality from each group of associated vehicle terminals, and based on the mobile communication network, only transmit the upgrade file to the determined target vehicle terminal.

[0046] Step S204: establishing a local area network communication link between the target vehicle end and the associated non-target vehicle end.

[0047] Exemplarily, the target vehicle end 102 can automatically establish a local area network in response to the completion of the upgrade file transmission, and wait for the non-target vehicle end to connect to the local area network, thereby forming a local area network communication link between the target vehicle end 102 and the non-target vehicle end. The local area network can be a wireless local area network (such as Wi-Fi) or a wired local area network (such as Ethernet).

[0048] Step S206: sending the upgrade file to the associated non-target vehicle terminal based on the local area network communication link, so that the associated non-target vehicle terminal upgrades itself based on the upgrade file.

[0049] In one possible implementation, the target vehicle end 102 may send the upgrade file to the associated non-target vehicle end in a broadcast manner based on the local area network communication link. In another possible implementation, the target vehicle end 102 may obtain the communication address of the associated non-target vehicle end based on the local area network communication link, and send the upgrade file to the associated non-target vehicle end in a unicast manner.

[0050] In the above-mentioned vehicle remote upgrade method, by comparing the signal quality of the mobile communication network between multiple vehicle terminals, the target vehicle terminal with better signal quality among the associated vehicle terminals is determined, and the upgrade file is transmitted to the target vehicle terminal, which can improve the success rate of the upgrade file transmission and reduce the amount of resources consumed in the entire transmission process; after receiving the upgrade file, the target vehicle terminal forwards the upgrade file to other vehicle terminals based on the establishment of a local area network, so that as long as some vehicle terminals can be connected to the cloud platform, other vehicle terminals can automatically network and upgrade in the local area network. Therefore, when multiple vehicle sections are operating in an environment with poor mobile communication network quality, the success rate of batch upgrades is improved.

[0051] In an exemplary embodiment, as shown in FIG4 , the vehicle remote upgrade method may further include:

[0052] Step S201, sending its own location information to the cloud platform so that the cloud platform can determine the association relationship between multiple vehicle terminals based on the location information of multiple vehicle terminals; the distance between the associated vehicle terminals is less than or equal to the first communication distance, and the first communication distance represents the communication distance corresponding to the local area network communication link.

[0053] The first communication distance may be the communication distance that any of the associated vehicle terminals can achieve based on the local area network communication link. In a possible implementation, the cloud platform may perform Euclidean clustering on the location information of multiple vehicle terminals to determine the association relationship between vehicle terminals of the same category; when the distance between the associated vehicle terminals is less than or equal to the first communication distance, the association relationship is determined to be effective; when the distance between the associated vehicle terminals is greater than the first communication distance, the vehicle terminals of the same category are grouped again.

[0054] In this embodiment, by determining the association relationship between vehicle terminals based on real-time location information and ensuring that the associated vehicle terminals can communicate based on a local area network communication link, the flexibility and efficiency of the target vehicle terminal forwarding upgrade files to non-target vehicles can be improved.

[0055] In an exemplary embodiment, as shown in FIG5 , the above step S206 may include:

[0056] Step S2061, sending the upgrade file to the broadcast address of the local area network communication link, so that the associated non-target vehicle terminal receives the upgrade file based on monitoring the broadcast address.

[0057] For example, the target vehicle end 102 can encapsulate the upgrade file into a data packet based on the UDP (User Datagram Protocol) protocol and send it to a specific broadcast address on the local area network communication link. The non-target vehicle end on the local area network communication link can monitor the broadcast address, receive the data packet and extract the upgrade file therein. Optionally, the target vehicle end 102 can send the upgrade file based on the broadcast function of the local area network itself.

[0058] In this embodiment, by forwarding the upgrade file to non-target vehicles in a broadcasting manner, the target vehicle does not need to establish connections with the non-target vehicles one by one, thereby reducing the waiting time of the non-target vehicles and further improving the efficiency of the target vehicle in forwarding the upgrade file to the non-target vehicle.

[0059] In an exemplary embodiment, please continue to refer to FIG. 5 , the above-mentioned vehicle remote upgrade method may further include:

[0060] Step S205, assigning respective unique identification information to each non-target vehicle terminal that joins the local area network communication link; the unique identification information is used by the target vehicle terminal to send the upgrade file to the corresponding non-target vehicle terminal based on the unique identification information.

[0061] Exemplarily, please refer to FIG6 , the unique identification information of the non-target vehicle terminal may be a number (including 1, 2 to n1 and 1, 2 to n2 in FIG6 ). The target vehicle terminal 102 may reallocate the unique identification information to each non-target vehicle terminal in response to multiple non-target vehicle terminals being connected to the local area network of the target vehicle terminal 102 , so that the target vehicle terminal 102 may accurately identify and manage each non-target vehicle terminal (e.g., broadcast address allocation, status monitoring, troubleshooting, etc.). Furthermore, the target vehicle terminal 102 may forward the upgrade file to the non-target vehicle with the unique identification information in a broadcast manner, thereby realizing effective management and upgrade of the newly added non-target vehicle terminals.

[0062] In an exemplary embodiment, as shown in FIG7 , the vehicle remote upgrade method may further include:

[0063] Step S2081, based on the local area network communication link, receiving the upgrade execution result replied by the associated non-target vehicle end.

[0064] Exemplarily, the upgrade execution result may include whether the upgrade is successful, log information, or an error code, etc.

[0065] Step S2082: uploading the upgrade execution result to the cloud platform based on the mobile communication network, so that the cloud platform can analyze the upgrade execution result.

[0066] For example, after collecting the upgrade execution results of all associated non-target vehicles, the target vehicle end 102 can upload these results to the cloud platform through the mobile communication network. After receiving these data, the cloud platform will analyze and process them to evaluate the success rate of the entire batch upgrade process, identify possible problem areas, and provide guidance for subsequent operations.

[0067] Optionally, for the vehicle ends that failed to upgrade, the cloud platform can again determine the association relationship between these vehicle ends based on the location information of these vehicle ends, and then send the upgrade file to the target vehicle ends that have been determined again based on the mobile communication network.

[0068] Further, please continue to refer to FIG. 7 , the above vehicle remote upgrade method may also include:

[0069] Step S207, sending the communication address of the target vehicle end to the associated non-target vehicle end, so that the associated non-target vehicle end replies with its own upgrade execution result based on the communication address of the target vehicle end.

[0070] For example, after the upgrade file is transmitted, the target vehicle end 102 can send its communication address (for example, IP address and port number) to the non-target vehicle end that has received the upgrade file. Then, the non-target vehicle end directly transmits its own upgrade execution result to the target vehicle end 102 in a unicast manner, ensuring that each non-target vehicle end can quickly and accurately feedback the upgrade execution result, so as to facilitate timely discovery of problems and take corresponding treatment measures.

[0071] To summarize, in the above-mentioned vehicle remote upgrade method, by comparing the signal quality of the mobile communication network between multiple vehicle terminals, the target vehicle terminal with better signal quality among the associated vehicle terminals is determined, and the upgrade file is transmitted to the target vehicle terminal, which can improve the success rate of the upgrade file transmission and reduce the amount of resources consumed in the entire transmission process; after receiving the upgrade file, the target vehicle terminal forwards the upgrade file to other vehicle terminals based on the establishment of a local area network, so that as long as some vehicle terminals can be connected to the cloud platform, other vehicle terminals can automatically network and upgrade in the local area network. Therefore, when multiple vehicle sections are operating in an environment with poor mobile communication network quality, the success rate of batch upgrades is improved.
