[0026] As mentioned above, with the development of the new energy vehicle field, cars have added functions such as intelligent navigation systems, intelligent entertainment systems, and 360° panoramic images. The dash cam installed in the car can record the video images and sounds during driving, and the recorded video images and sounds can be used to record the external scenery of the vehicle and determine the responsibility for traffic accidents. At present, the video images and sounds recorded by the dash cam can only be viewed from the car computer. However, when viewing the video images and sounds recorded by the dash cam from the car computer, users cannot save the required video images and sounds such as the external scenery of the vehicle, and the user experience of viewing the video images through the car computer is poor.

[0027] An embodiment of the present application provides a data transmission method, in which the vehicle side responds to a near field communication request sent by the mobile side, establishes a near field communication channel with the mobile side, receives a data transmission request sent by the mobile side through the near field communication, and transmits target data to the mobile side through the near field communication according to the data transmission request, so that the vehicle side transmits data to the mobile side through the near field communication, thereby enabling the mobile side to obtain the video images and sounds of the driving process saved by the vehicle side. Compared with the prior art, the user can selectively save the video images and sounds of the driving process saved by the vehicle side, and can view the video images and sounds that need to be saved at any time through the mobile side after obtaining them on the mobile side, thereby improving the user experience.

[0028] The data transmission method provided by the present application is described below by way of examples.

[0029] Figure 1 is a flow chart of a data transmission method provided in an embodiment of the present application, and the data transmission method is applied to a vehicle side, such as Figure 1 As shown, the data transmission method includes the following steps 101 to 103:

[0030] Step 101: In response to a near field communication request sent by a mobile terminal, establish a near field communication channel with the mobile terminal.

[0031] The vehicle side turns on the local area network, responds to the access of the mobile side, and establishes a local area network connection with the mobile side. For example, the vehicle side turns on the WIFI hotspot, and the mobile side searches for and connects to the WIFI hotspot turned on by the vehicle side. The vehicle side and the mobile side are connected through the WIFI hotspot, so that the vehicle side and the mobile side are located in the same local area network. The vehicle side receives and responds to the near field communication (NFC) request sent by the mobile side, and establishes a near field communication channel with the mobile side, wherein the near field communication channel can be used for data transmission.

[0032] Step 102: Receive a data transmission request sent by a mobile terminal via near field communication.

[0033] The vehicle end receives a data transmission request sent by the mobile end through near field communication, wherein the data transmission request indicates target data that needs to be transmitted from the vehicle end to the mobile end.

[0034] Step 103: According to the data transmission request, the target data is transmitted to the mobile terminal through near field communication.

[0035] After receiving the data transmission request, the vehicle determines the target data to be transmitted to the mobile terminal according to the data transmission request, and transmits the target data to the mobile terminal through the established near field communication channel by means of near field communication.

[0036] In an embodiment of the present application, the vehicle side responds to a near-field communication request sent by the mobile side, establishes a near-field communication channel with the mobile side, receives a data transmission request sent by the mobile side through near-field communication, and transmits target data to the mobile side through near-field communication according to the data transmission request, thereby realizing data transmission from the vehicle side to the mobile side through near-field communication, thereby enabling the mobile side to obtain the video images and sounds of the driving process saved by the vehicle side. Compared with the prior art, the user can selectively save the video images and sounds of the driving process saved by the vehicle side, and can view the video images and sounds that need to be saved on the mobile side at any time through the mobile side, thereby improving the user experience.

[0037] In one possible implementation, when establishing a near field communication channel with a mobile terminal in response to a near field communication request sent by the mobile terminal, the near field communication request sent by the mobile terminal can be received, and the mobile terminal can be authenticated through near field communication based on the near field communication request. If the authentication is successful, a near field communication channel is established with the mobile terminal.

[0038] The vehicle side receives the near-field communication request sent by the mobile side, and performs identity authentication on the mobile side through near-field communication according to the near-field communication request. If the identity authentication is successful, a near-field communication channel is established with the mobile side. If the identity authentication is not successful, a near-field communication channel is not established with the mobile side. In one example, after the vehicle side receives the near-field communication request sent by the mobile side, it verifies through near-field communication whether the same owner account and the same vehicle VIN code are logged in on the vehicle side and the mobile side driving recorder app. If the same owner account and the same vehicle VIN code are logged in on the vehicle side and the mobile side driving recorder app, the identity authentication is successful, and a near-field communication channel is established between the vehicle side and the mobile side.

[0039] In an embodiment of the present application, the vehicle end receives a near-field communication request sent by the mobile end, and authenticates the mobile end through near-field communication based on the near-field communication request. If the authentication is successful, a near-field communication channel is established with the mobile end. This allows data transmission through near-field communication when the authentication is successful, thereby ensuring the security of data transmission.

[0040] In one possible implementation, when transmitting target data to a mobile terminal via near field communication, if the near field communication channel is interrupted, the transmitted target data is recorded. When the near field communication channel is re-established, the target data to be transmitted is transmitted to the mobile terminal via near field communication, wherein the target data to be transmitted is the target data that has not been transmitted.

[0041] When transmitting target data to the mobile terminal through near-field communication, if the near-field communication channel for transmitting the target data is interrupted, for example, the user actively triggers to pause data transmission, network failure or terminal device failure causes data transmission interruption, etc., the vehicle end will record the transmitted target data, that is, the information of the sub-data stream in the target data sub-data stream that the vehicle end has transmitted to the mobile terminal. When the near-field communication channel is re-established, the vehicle end transmits the sub-data stream in the target data sub-data stream that has not been transmitted to the mobile terminal to the mobile terminal through near-field communication based on the information of the sub-data stream in the target data sub-data stream that the vehicle end has transmitted to the mobile terminal, that is, the remaining sub-data stream to be transmitted after the sub-data breakpoint where the transmission of the vehicle end to the mobile terminal is interrupted. For example: the target data is divided into four sub-data streams, and the near-field communication channel is interrupted when transmitting the third sub-data stream. When the near-field communication channel is re-established, the vehicle end continues to transmit the third sub-data stream and the fourth sub-data stream to the mobile terminal through near-field communication from the position where the transmission of the third sub-data stream is interrupted.

[0042] In an embodiment of the present application, if the near-field communication channel is interrupted, the transmitted target data is recorded. When the near-field communication channel is re-established, the target data to be transmitted is transmitted to the mobile terminal via near-field communication, thereby enabling the target data to be transmitted from the location where the data transmission was interrupted to continue. When the target data transmission is interrupted, there is no need to re-perform complete data transmission, thereby improving the efficiency of data transmission.

[0043] Figure 2 is a flow chart of another data transmission method provided in an embodiment of the present application, and the data transmission method is applied to a mobile terminal, such as Figure 2 As shown, the data transmission method includes the following steps 201 to 203:

[0044] Step 201: Send a near field communication request to the vehicle.

[0045] The mobile terminal accesses the LAN opened by the vehicle terminal and establishes a LAN connection with the vehicle terminal. For example, the vehicle terminal opens a WIFI hotspot, and the mobile terminal searches for and connects to the WIFI hotspot opened by the vehicle terminal. Then, the vehicle terminal and the mobile terminal are connected through the WIFI hotspot, so that the vehicle terminal and the mobile terminal are in the same LAN, and the mobile terminal sends a near-field communication request to the vehicle terminal.

[0046] Step 202: After establishing a near field communication channel with the vehicle end, a data transmission request is sent to the vehicle end via near field communication.

[0047] After establishing a near field communication channel with the vehicle end, the mobile end sends a data transmission request to the vehicle end through near field communication, wherein the data transmission request indicates target data that needs to be transmitted from the vehicle end to the mobile end.

[0048] Step 203: Receive the target data transmitted by the vehicle end in response to the data transmission request.

[0049] The mobile terminal receives several sub-data streams of the target data transmitted by the vehicle terminal in response to the data transmission request through the near field communication channel, and saves the sub-data streams to the directory specified by the mobile terminal. Before obtaining the sub-data stream from the vehicle terminal each time, it determines whether the download has been completed. If the download has not been completed, it continues to obtain the sub-data stream transmitted by the vehicle terminal. If the download is completed, a notification of data transmission completion is sent to the vehicle terminal, so that the vehicle terminal stops the data transmission task. The target data transmitted by the vehicle terminal in response to the data transmission request received by the mobile terminal can be saved in the storage space of the mobile terminal so that it can be viewed at any time through the mobile terminal.

[0050] In an embodiment of the present application, the mobile terminal sends a near-field communication request to the vehicle terminal. After establishing a near-field communication channel with the vehicle terminal, the mobile terminal sends a data transmission request to the vehicle terminal via near-field communication, and receives the target data transmitted by the vehicle terminal in response to the data transmission request, so that the mobile terminal receives the data transmitted by the vehicle terminal via near-field communication, thereby enabling the mobile terminal to view the video images and sounds of the driving process saved by the vehicle terminal on the mobile terminal. Compared with the prior art, the user can selectively save the video images and sounds of the driving process saved by the vehicle terminal, and can view the video images and sounds that need to be saved on the mobile terminal at any time through the mobile terminal, thereby improving the user experience.

[0051] In one possible implementation, after establishing a near-field communication channel with the vehicle-end, when sending a data transmission request to the vehicle-end through near-field communication, after establishing a near-field communication channel with the vehicle-end, a data query request can be sent to the vehicle-end through near-field communication, and a data list sent by the vehicle-end in response to the data query request can be received, and according to the data list, a data transmission request corresponding to the target data can be sent to the vehicle-end through near-field communication.

[0052] After the mobile terminal establishes a near-field communication channel with the vehicle terminal, it sends a data query request to the vehicle terminal through the near-field communication, wherein the data query request includes at least one of querying the type of data stored on the vehicle terminal, querying the data content contained in a certain data type stored on the vehicle terminal, and querying the data content stored on a specific date on the vehicle terminal. The mobile terminal receives the data list sent by the vehicle terminal in response to the data query request, determines the target data requested to be transmitted by the vehicle terminal in the data list, and sends a data transmission request corresponding to the target data to the vehicle terminal through the near-field communication. For example, the mobile terminal sends a request to view pictures stored in the past week to the vehicle terminal through the near-field communication. The mobile terminal receives a list of 50 pictures stored in the past week sent by the vehicle terminal, and can select 20 pictures that need to be downloaded to the mobile terminal, and sends a data transmission request for transmitting the 20 pictures to the vehicle terminal.

[0053] In an embodiment of the present application, after establishing a near-field communication channel with the vehicle end, a data query request is sent to the vehicle end via near-field communication, and a data list sent by the vehicle end in response to the data query request is received. According to the data list, a data transmission request corresponding to the target data is sent to the vehicle end via near-field communication. This allows the mobile end to view the data locally stored on the vehicle end, thereby enabling the mobile end to select the target data that needs to be transmitted from the vehicle end to the mobile end, allowing the user to save the data recorded by the vehicle's driving recorder as needed.

[0054] In a possible implementation, the data transmission method may also receive a data sharing request sent by the vehicle end, and receive the target data sent by the vehicle end through near field communication according to the data sharing request.

[0055] The vehicle end can also actively share data with the mobile end. Specifically, the mobile end receives the data sharing request sent by the vehicle end, obtains the target data information indicated by the data sharing request, and receives the target data sent by the vehicle end through near-field communication. In one example, after receiving the data sharing request, the mobile end can detect whether the target data exists in the storage space of the mobile end. If the target data does not exist in the storage space of the mobile end, a data transmission request is sent to the vehicle end, and the target data sent by the vehicle end in response to the data transmission request is received through near-field communication. If the target data exists in the storage space of the mobile end, a notification that the data exists is sent to the vehicle end.

[0056] In an embodiment of the present application, a data sharing request sent by the vehicle side is received, and according to the data sharing request, the target data sent by the vehicle side is received through near-field communication. The target data sent by the vehicle side in response to the data transmission request is received through near-field communication. This allows the mobile side to receive the target data actively shared from the vehicle side, and when the target data exists in the storage space of the mobile side, a notification that the data exists can be sent to the vehicle side, thereby avoiding the transmission of duplicate data.

[0057] In one possible implementation, when receiving the target data transmitted by the vehicle end in response to the data transmission request, the occupied space of the sub-data stream transmitted by the vehicle end in response to the data transmission request can be obtained, wherein the target data includes at least one sub-data stream, and the remaining space capacity is obtained. If the occupied space of the sub-data stream is less than or equal to the remaining space capacity, the sub-data stream is received; if the occupied space of the sub-data stream is greater than the remaining space capacity, an insufficient space signal is sent to the vehicle end to cause the vehicle end to stop transmitting the target data.

[0058] When the vehicle receives a data transmission request sent by the mobile terminal through near-field communication, the target data can be divided into several sub-data streams, and several sub-data streams are sent to the mobile terminal through near-field communication to transmit the target data. In one example, the vehicle sends a binary sub-data stream of 512K in size to the mobile terminal each time through near-field communication.

[0059] The mobile terminal obtains the occupied space of the sub-data stream transmitted by the vehicle terminal in response to the data transmission request and the remaining space capacity of the sub-data stream that can be obtained in the storage space of the mobile terminal. If the occupied space of the sub-data stream is less than or equal to the remaining space capacity, the mobile terminal receives the sub-data stream of the target data transmitted by the vehicle terminal. For example, if the size of the sub-data stream is 512kb and the remaining space of the mobile terminal is 1024kb, the sub-data stream transmitted by the vehicle terminal is received. If the occupied space of the sub-data stream is greater than the remaining space capacity, the mobile terminal does not receive the sub-data stream transmitted by the vehicle terminal, and sends an insufficient space signal to the vehicle terminal to stop the vehicle terminal from transmitting the target data. For example, if the size of the sub-data stream is 512kb and the remaining space of the mobile terminal is 256kb, the sub-data stream transmitted by the vehicle terminal is not received, and an insufficient space signal is sent to the vehicle terminal to stop the vehicle terminal from transmitting the target data.

[0060] In an embodiment of the present application, the occupied space of the sub-data stream transmitted by the vehicle end in response to a data transmission request is obtained, wherein the target data includes at least one sub-data stream, and the remaining space capacity is obtained. If the occupied space of the sub-data stream is less than or equal to the remaining space capacity, the sub-data stream is received. If the occupied space of the sub-data stream is greater than the remaining space capacity, an insufficient space signal is sent to the vehicle end to stop transmitting the target data. This realizes notifying the vehicle end to stop data transmission when the remaining space on the mobile end is insufficient, thereby avoiding abnormalities caused by data transmission failure.

[0067] In one possible implementation, the transmission unit 303 may also record the transmitted target data if the near-field communication channel is interrupted, and when the near-field communication channel is re-established, transmit the target data to be transmitted to the mobile terminal via near-field communication, wherein the target data to be transmitted is the target data that has not been transmitted.

[0074] In a possible implementation, the data transmission device 400 may also receive a data sharing request sent by the vehicle end; and receive the target data sent by the vehicle end through near field communication according to the data sharing request.

[0075] In a possible implementation, the acquisition unit 403 can also obtain the occupied space of the sub-data stream transmitted by the vehicle end in response to the data transmission request, wherein the target data includes at least one sub-data stream; obtain the remaining space capacity; if the occupied space of the sub-data stream is less than or equal to the remaining space capacity, receive the sub-data stream; if the occupied space of the sub-data stream is greater than the remaining space capacity, send an insufficient space signal to the vehicle end to cause the vehicle end to stop transmitting the target data.
