In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0057] Please refer to Figure 1 , which shows a flow chart of a method for data feedback provided by an embodiment of the present application. The method for data feedback is applied to an autonomous driving vehicle and may specifically include:

[0058] Step 101: Obtain a transmission data volume threshold corresponding to the data to be processed.

[0059] Step 102: Based on the transmission data amount threshold, obtain a plurality of first data slices corresponding to the data to be processed.

[0060] Step 103: Transmit each first data slice to the server to determine a first response status of the server corresponding to each first data slice.

[0061] Step 104: Determine a corresponding slice adjustment strategy based on the first response.

[0062] Step 105: Based on the corresponding slice adjustment strategy and the transmission data amount threshold, the slice size of the untransmitted data is adjusted to obtain a plurality of different adjusted data slices.

[0063] Step 106: Transmit multiple different adjusted data slices to the server.

[0064] At this point, a plurality of different adjusted data slices are transmitted to the server until the transmission of the data to be processed is completed, that is, the data to be processed is transmitted as a whole to the server.

[0065] It should be noted that the data to be processed may be a file data package, which may include but is not limited to data communicated between various modules of the vehicle, perception data of the vehicle, behavior decisions of the vehicle, and the like.

[0066] It should be noted that the first response situation may include multiple different response situations. Each response situation may have a corresponding slice adjustment strategy.

[0067] It should be noted that the untransmitted data may be data that has not been uploaded to the server. The untransmitted data may include data that has not been successfully uploaded and data that has not been processed for transmission.

[0068] It should be noted that part or all of the execution subject of steps 101 to 106 may be an application located in the local terminal, or may also be a functional unit such as a plug-in or software development kit (SDK) set in the application located in the local terminal, or may also be a processing engine located in a network-side server, or may also be a distributed system located on the network side, for example, a processing engine or distributed system in a data processing platform on the network side, etc. This embodiment does not specifically limit this.

[0069] It is understandable that the application may be a local program (nativeApp) installed on the local terminal, or may be a webpage program (webApp) of a browser on the local terminal, which is not limited in this embodiment.

[0070] In this way, by obtaining a transmission data volume threshold corresponding to the data to be processed, multiple first data slices corresponding to the data to be processed can be obtained based on the transmission data volume threshold, and each first data slice can be transmitted to the server to determine the first response status of the server corresponding to each first data slice, and the corresponding slice adjustment strategy can be determined based on the first response status, and the slice size of the untransmitted data can be adjusted based on the corresponding slice adjustment strategy and the transmission data volume threshold to obtain multiple different adjusted data slices, and the multiple different adjusted data slices can be transmitted to the server. Since the slice size of each data transmission can be dynamically adjusted based on the response status to detect the boundary of the current network situation, it is possible to ensure that the data is effectively returned while not blocking the network, thereby optimizing the reliability of data return.

[0071] Optionally, in a possible implementation of this embodiment, in step 102, the first slice size corresponding to the data to be processed can be determined based on the transmission data volume threshold, and then the data to be processed can be segmented based on the first slice size to obtain multiple first data slices.

[0072] In this implementation, the data transmission volume threshold may be determined based on the data transmission volume range obtained by the vehicle end sending an upload data request to the server end. The data transmission volume threshold may be a boundary threshold of the data transmission volume that the server end can receive each time.

[0073] In a specific implementation process of this implementation method, first, the autonomous driving vehicle can send an upload data request to the server. Secondly, the server determines the range of the amount of transmission data that can be received each time based on the upload data request. Thirdly, the server returns the range of the amount of transmission data to the autonomous driving vehicle. Thirdly, the autonomous driving vehicle can determine the threshold of the amount of transmission data based on the current network status and the range of the amount of transmission data.

[0074] In this way, the data to be processed can be segmented by the transmission data volume threshold to obtain multiple first data slices, so that the reliability of the subsequent transmission of the multiple first data slices to the server can be further guaranteed, thereby ensuring the reliability of data return.

[0075] Optionally, in a possible implementation of this embodiment, in step 104, in response to the first response situation being a response timeout, it can be determined that the corresponding slice adjustment strategy is the first adjustment strategy. Further, in step 105, the slice size of the untransmitted data can be adjusted based on the first adjustment strategy and the transmission data amount threshold to obtain multiple different adjusted data slices.

[0076] In a specific implementation process of this implementation method, first, based on the preset coefficient and the first slice size, the second slice size is calculated. Secondly, the untransmitted data can be segmented based on the second slice size to obtain multiple second data slices. Thirdly, each second data slice is transmitted to the server to determine the second response status corresponding to each second data slice. Thirdly, in response to the second response status being a normal response, the size of each corresponding second data slice is increased based on the transmission data volume threshold and the preset data volume value to obtain multiple increased second data slices.

[0077] In this implementation, the second slice size is determined according to the product of a preset coefficient and the first slice size. Preferably, the preset coefficient may be a value less than 1 and greater than 0, for example, the preset coefficient may be 0.5. The second slice size may be half of the first slice size. The first slice size may be the size of the first data slice when the first response situation is a response timeout situation.

[0078] In this implementation, the preset data volume value can be determined according to the actual vehicle-side network conditions. Preferably, the preset data volume value can be 1 kilobyte (kb).

[0079] In a specific implementation process of this implementation method, first, it can be determined whether the response of the server exceeds the preset first time length to determine whether the first response situation is a response timeout. Secondly, when the first response situation is a response timeout, the untransmitted data can be segmented based on the second slice size to obtain multiple second data slices. Thirdly, each second data slice is transmitted to the server to determine the second response situation corresponding to each second data slice. Thirdly, in response to the second response situation being a normal response, the size of each corresponding second data slice is increased based on the transmission data volume threshold and the preset data volume value to obtain multiple increased second data slices.

[0080] In a specific implementation process, the preset first duration may be determined by an actual business scenario. For example, the preset duration may be 1 minute.

[0081] In another specific implementation process of this implementation method, for any second data slice, in response to the second response condition being a normal response, the size of the corresponding second data slice can be increased by a preset data amount value to obtain an increased second data slice. The increased second data slice is transmitted to the server to determine that the second response condition of the size of the increased second data slice is a normal response, and the size of the increased second data slice can be further increased by a preset data amount value to obtain a new increased second data slice, and the above steps are executed repeatedly until the size of the latest increased second data slice reaches the transmission data amount threshold. When the size of the latest increased second data slice is the transmission data amount threshold, the untransmitted data can be sliced ​​according to the size of the latest increased second data slice to obtain multiple new data slices, and each untransmitted new data slice is uploaded to the server based on the preset second duration.

[0082] In this implementation, the preset second duration can be determined according to actual business requirements. For example, the preset second duration can be 3 minutes to 5 minutes. In this way, the stability of data transmission can be guaranteed.

[0083] Exemplarily, when the network deteriorates, for example, the interval for receiving a response increases, resulting in a response timeout, the size of the data slice to be sent can be adjusted to half of the transmission data volume threshold or the temporary upper bound and then continue to be sent. Each time a response is successfully received, the slice size is increased by 1KB until the slice size reaches the transmission data volume threshold or the temporary upper bound. Here, the temporary upper bound can be the data size value of the data slice for which the response timeout occurs.

[0084] In this way, when the first response situation is a response timeout, that is, when the network status deteriorates, the size of the slice sent each time can be dynamically adjusted based on the response situation and the corresponding adjustment strategy, and the boundary of the current network situation can be detected to realize data backhaul without blocking the network.

[0085] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementation to implement the data return method of this embodiment. For a detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0086] Optionally, in a possible implementation of this embodiment, in step 104, specifically in response to the first response situation being a non-response, the corresponding slice adjustment strategy can be determined to be a second adjustment strategy. Further, in step 105, the slice size of the non-transmitted data can be adjusted based on the second adjustment strategy and the transmission data volume threshold to obtain multiple different adjusted data slices.

[0087] In a specific implementation process of this implementation method, first, the untransmitted data can be segmented based on a preset third slice size to obtain multiple third data slices. Secondly, the third data slice can be transmitted to the server to determine the third response of the server corresponding to the third data slice. Thirdly, in response to the third response being normal, the size of each corresponding third data slice is increased based on a preset data volume value and the transmission data volume threshold to obtain multiple increased third data slices.

[0088] In this implementation, the preset third slice size may be determined based on the minimum amount of data that can be transmitted. For example, the preset third slice size may be 1 kb.

[0089] Exemplarily, when the network is unavailable, that is, the first response is no response, the size of the data slice in the current network unavailable situation is set as a temporary upper limit, the untransmitted data is segmented and processed to obtain multiple 1KB data slices, and a 1KB data slice is sent to the server. If the response from the server is normal, the data slice corresponding to the data that has not been successfully transmitted can be increased to a 2KB data slice, and then the 2KB data slice is sent to the server to obtain a response, and the cycle is executed until the size of the data slice reaches the transmission data volume threshold. Again, according to the size of the transmission data volume threshold, upload the untransmitted data until all the data to be processed is transmitted to the server.

[0090] In this way, when the first response situation is no response, that is, the network is unavailable, the size of the slice sent each time can be dynamically adjusted based on the response situation and the corresponding adjustment strategy to detect the boundary of the current network situation to realize data backhaul without blocking the network.

[0091] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementation to implement the data return method of this embodiment. For a detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0092] Optionally, in a possible implementation of this embodiment, in step 104, in response to the first response condition being a normal response, the untransmitted first data slice and the transmission data range corresponding to the untransmitted first data slice are obtained, and then based on the transmission data range corresponding to the untransmitted first data slice, the untransmitted first data slice is transmitted to the server.

[0093] In this implementation, after the vehicle side transmits the data to be processed to the server side, the server side assembles the received data based on a preset assembly strategy and stores the assembled data.

[0094] In a specific implementation process of this implementation method, first, after receiving the data slice, the server can use the crc32 check algorithm to verify the received data slice. Secondly, if the verification is successful, a normal response message can be returned to the vehicle. Thirdly, if the verification fails, an abnormal response message can be returned to the vehicle, and then the vehicle can adjust the data slice according to actual business needs and send the adjusted data slice again.

[0095] In this way, the reliability and security of the transmitted data can be guaranteed by verifying the data slices.

[0096] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementation to implement the data return method of this embodiment. For a detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0104] Optionally, in a possible implementation of this embodiment, the first adjustment unit 205 is used to calculate the second slice size based on a preset coefficient and the first slice size; based on the second slice size, segment the untransmitted data to obtain multiple second data slices; transmit each second data slice to the server to determine the second response status corresponding to each second data slice; in response to the second response status being a normal response, increase the size of each corresponding second data slice based on the transmission data volume threshold and the preset data volume value to obtain multiple increased second data slices.

[0107] In this embodiment, the first acquisition unit can obtain a transmission data volume threshold corresponding to the data to be processed, and then the first acquisition unit can obtain multiple first data slices corresponding to the data to be processed based on the transmission data volume threshold. The first transmission unit transmits each first data slice to the server to determine the first response status of the server corresponding to each first data slice.

The first adjustment unit adjusts the slice size of the untransmitted data based on the corresponding slice adjustment strategy and the transmission data volume threshold to obtain multiple different adjusted data slices, so that the second transmission unit can transmit the multiple different adjusted data slices to the server. Since the slice size of each data transmission can be dynamically adjusted based on the response status to detect the boundary of the current network situation, it is possible to ensure that the data is effectively returned while not blocking the network, thereby optimizing the reliability of data return.
