[0020] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and in detail below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in the field based on the embodiments in the embodiments of the present disclosure should fall within the scope of protection of the embodiments of the present disclosure.

[0021] The specific implementation of the embodiments of the present disclosure will be further described below with reference to the accompanying drawings.

[0022] Figure 1The system architecture 100 is suitable for implementing the method or device for data chain transmission of each embodiment of the present disclosure. As shown in the figure, the present embodiment can realize the chain propagation of vehicle-side data packets through the self-organized networks 102a and 102b between vehicles. For example, vehicle 104a can be used as a data providing node to provide vehicle-side data download services to each data requesting node (for example, vehicle 104b, vehicle 104c, and vehicle 104d) through the self-organized network 102a. Among them, after completing the task of downloading vehicle-side data, vehicle 104b can be converted from a data requesting node to a data providing node, and continue to provide vehicle data download services to each data requesting node (for example, vehicle 104e and vehicle 104f) through the self-organized network 102b. Through the data chain propagation method between vehicles, the dependence of the vehicle-side data download operation on the content distribution network (CDN) and the network traffic consumed by executing data transmission can be significantly reduced.

[0023] In some embodiments, vehicles can establish ad hoc network connections through on-board TBOX, Wi-Fi and other communication modules to form a local communication network between vehicles.

[0024] Based on the above system architecture 100, each embodiment of the present disclosure provides a vehicle-side data chain propagation method, which is described below through each embodiment.

[0025] Vehicle-side data chain transmission method

[0026] Figure 2 The processing flow of the vehicle-side data chain propagation method of the exemplary embodiment of the present disclosure mainly includes the following steps:

[0027] Step 202: In response to the vehicle's request to download the vehicle-side data packet, identify the vehicle as a data requesting node for the vehicle-side data packet.

[0028] In some embodiments, the vehicle-side data packet may be an upgrade software package of the vehicle; or, in the case where the upgrade software package of the vehicle is divided into multiple sub-data packages, the vehicle-side data packet may be any sub-data package in the upgrade software package.

[0029] Exemplarily, according to the download request of the vehicle 104b corresponding to the vehicle-side data packet A, the vehicle 104b may be identified as a data requesting node of the vehicle-side data packet A.

[0030] Step 204 : Search for each data providing node of the vehicle-side data packet within the communication range of the vehicle, detect the communication parameters between the vehicle and each data providing node, and determine one of the data providing nodes as the target data providing node.

[0031] In some embodiments, each surrounding vehicle that can establish a communication connection with the vehicle and each downloadable data packet of each surrounding vehicle can be searched within the communication range of the vehicle, and the identification information of the vehicle-side data packet is matched with the identification information of each downloadable data packet, and each surrounding vehicle containing the vehicle-side data packet is determined as each data providing node of the vehicle-side data packet. For example, if the various downloadable data provided by vehicle 104a include vehicle-side data packet A, vehicle 104a is the data providing node of vehicle-side data packet A.

[0032] In some embodiments, the communication parameters between the vehicle and each data providing node can be detected, and the communication quality of the vehicle corresponding to each data providing node can be evaluated based on the given communication requirements of the vehicle-side data packet and the communication parameters between the vehicle and each data providing node. Based on the communication quality scores of the vehicle corresponding to each data providing node, a data providing node with the highest communication quality score is determined as the target data providing node.

[0033] In some embodiments, the communication parameter includes signal strength. Exemplarily, the data requesting node may allocate more request weights (or request points) to data providing nodes with stronger signal strengths according to the signal strengths of the data providing nodes, and determine the communication quality scores of the data providing nodes based on the request weights (or request points) of the data providing nodes.

[0034] Step 206: Download the vehicle-side data packet from the target data providing node, and in response to the detection result of the completion of the download of the vehicle-side data packet, update the vehicle identifier to the data providing node of the vehicle-side data packet.

[0035] For example, reference Figure 1 , vehicle 104b can download the vehicle-side data packet A from vehicle 104a, and when it is detected that vehicle 104b has completed downloading the vehicle-side data packet A, the identification of vehicle 104b can be updated from the data request node of the vehicle-side data packet A to the data providing node of the vehicle-side data packet A, so as to continue to propagate the vehicle-side data packet A to other vehicles, thereby achieving a chain propagation effect of the vehicle-side data packet A.

[0036] In some embodiments, if the vehicle 104b encounters a transmission failure or data error during the process of downloading the vehicle-side data packet A from the vehicle 104a, the vehicle 104b will retransmit or verify according to the preset exception handling strategy. In addition, end-to-end encryption technology can be used to protect data security during the entire transmission process, and the identity of the vehicles involved in the transmission can be authenticated to prevent unauthorized access. Since the above technologies are all common knowledge in the field, this application will not elaborate on their specific implementation solutions.

[0037] Figure 3The processing flow of the vehicle-side data chain propagation method according to another exemplary embodiment of the present disclosure mainly includes the following steps:

[0038] Step 302: determine the identification information corresponding to each vehicle-side data packet downloaded in the vehicle.

[0039] In some embodiments, the vehicle may perform the following steps: Figure 2 The vehicle-side data chain transmission method shown in FIG. 1 downloads each vehicle-side data packet from other vehicles. Figure 1 In the example shown, vehicle 104b may download a vehicle-side data packet from vehicle 104a via self-organizing network 102a, and vehicle 104f may download a vehicle-side data packet from vehicle 104b via self-organizing network 102b.

[0040] In other embodiments, the vehicle may also download the vehicle-side data package from the cloud server through traditional OTA technology. Figure 1 , the vehicle 104a can download the vehicle-side data packet through the content distribution network 106. In other embodiments, when a vehicle (e.g., any one of the vehicles 104b to 104f) cannot download the vehicle-side data packet from other vehicles through the self-assembled network, the vehicle-side data packet can also be directly downloaded through the content distribution network 106.

[0041] In some embodiments, the vehicle-side data packet may be an upgrade software package of the vehicle; or, in the case where the upgrade software package of the vehicle is divided into multiple sub-data packages, the vehicle-side data packet may be any sub-data package in the upgrade software package.

[0042] Step 304: broadcast the vehicle's identification information and the identification information corresponding to each vehicle-side data packet within the vehicle's communication range.

[0043] In some embodiments, after the vehicle is started, the self-organizing network module can be initialized through the on-board TBOX or Wi-Fi, searching and connecting to surrounding vehicles to form a self-organizing network, and broadcasting the vehicle's identification information and the identification information of each vehicle-side data packet that can be downloaded by surrounding vehicles to surrounding vehicles through the self-organizing network.

[0044] Step 306: In response to each download request from each data requesting node, detect each signal strength of each data requesting node, and identify each vehicle-side data packet requested to be downloaded by each data requesting node.

[0045] For example, when vehicle 104a receives download requests from vehicles 104b, 104c, and 104d (data requesting nodes) through self-assembled network 102a, it can detect the signal strength of vehicles 104b, 104c, and 104d, and identify the vehicle-side data packets requested to be downloaded from vehicles 104b, 104c, and 104d.

[0046] Step 308: Determine at least one target data requesting node among the data requesting nodes.

[0047] In some embodiments, when the vehicle-side data packets requested to be downloaded by each data requesting node are the same, each data requesting node may be screened according to signal strength to determine at least one target data requesting node among the data requesting nodes.

[0048] In some embodiments, when the vehicle-side data packets requested to be downloaded by each data requesting node are different, the target data requesting node among the data requesting nodes may be determined in the following manner:

[0049] Based on the file size of each vehicle-side data packet and the signal strength between the vehicle and each data request node, the connection priority of each data request node is evaluated. According to the connection priority of each data request node and the maximum number of connection nodes of the vehicle, at least one of the data request nodes is determined as the target data request node.

[0050] In some embodiments, the signal strength weights of each data request node can be determined based on the file size of each vehicle-side data packet of each data request node, and the transmission scores of each data request node can be calculated based on the signal strengths between the vehicle and each data request node and the signal strength weights of each data request node. Then, based on the transmission scores of each data request node, the connection priorities of each data request node can be determined.

[0051] Specifically, the larger the file size of the vehicle-side data packet, the higher the requirement for signal strength. By scoring the signal strength of all potential data request nodes and combining the file size of the vehicle-side data packet as a weight, the comprehensive score of each data request node is calculated and the target data request node is screened based on it, which can improve the stability and reliability of file transmission.

[0052] In this embodiment, the connection relationship between the data providing node and the data requesting node can be "one-to-one" or "one-to-many". At least one of the data requesting nodes can be determined as the target data requesting node based on the maximum number of connected nodes of the vehicle and the connection priority of each data requesting node. For example, if the maximum number of connected nodes of the vehicle is 2, the two data requesting nodes with the highest connection priority can be determined as the target data requesting nodes.

[0053] Step 310: Transmit corresponding vehicle-side data packets to each target data requesting node.

[0054] To summarize, the present application performs data transmission between vehicles through self-organizing network technology between vehicles, which can achieve an exponential propagation effect, improve the download efficiency and rapid distribution of vehicle-side data, reduce the vehicle's dependence on cellular networks, and reduce data transmission costs.

[0055] Furthermore, the embodiment of the present application can further improve the efficiency of inter-vehicle self-organizing network transmission by detecting the communication quality between vehicles, and provide stability and reliability of vehicle-side data download. In addition, the dynamic adjustment strategy of the vehicle self-organizing network technology can be adaptively adjusted according to actual traffic conditions and vehicle distribution to adapt to different network conditions and vehicle density.

[0056] Figure 4 The following is a process flow chart of a vehicle-side software upgrade method according to an exemplary embodiment of the present disclosure. As shown in the figure, this embodiment mainly includes the following steps:

[0057] Step 402: Determine each sub-data package included in the vehicle-side software upgrade package.

[0058] In some embodiments, the version number of the software upgrade package to be upgraded on the vehicle side (for example, version 1.1) and the sub-data packages contained in the software upgrade package can be determined based on the baseline model of the vehicle side and the version number of the software upgrade package currently installed on the vehicle side (for example, version 1.0).

[0059] Step 404: Download each sub-data package in the upgrade software package from one or more data providing nodes to obtain a software upgrade package.

[0060] In this embodiment, the following can be used: Figure 2 The vehicle-side data chain propagation method embodiment shown downloads each sub-data package in the upgrade software package from one or more data providing nodes.

[0061] In some embodiments, reference Figure 1 , vehicle 104f can download all sub-data packets in the software upgrade package from vehicle 104b (data providing node); or, vehicle 104f can download a part of the sub-data packets in the software upgrade package from vehicle 104b (data providing node A), and download another part of the sub-data packets in the software upgrade package from vehicle 104c (data providing node B), and so on, until all sub-data packets in the software upgrade package are downloaded.

[0062] In this embodiment, after the vehicle 104f has downloaded all the sub-data packages in the upgrade software package, the complete upgrade software package can be obtained by splicing the sub-data packages.

[0063] Step 406: Use the software upgrade package to upgrade the vehicle-side software.

[0064] To sum up, the vehicle-side software upgrade method of this embodiment can realize segmented transmission of software upgrade packages to support more efficient data transmission and error recovery.

[0065] In addition, since different versions of software upgrade packages may share the same sub-data package, the vehicle-side software upgrade method of this embodiment provides a compatibility solution for propagating upgrade packages across vehicle models and brands to achieve a wider range of application scenarios.
