Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0018] In related technologies, a vehicle system may include multiple hosts. In order to enable each host to use Wi-Fi related functions, a Wi-Fi communication module is usually set in each host. In this way, the hardware cost of the vehicle system is relatively high.

[0019] To this end, an embodiment of the present application provides a vehicle-mounted system for reducing the hardware cost of the vehicle-mounted system.

[0020] Figure 1 This is a schematic diagram of the structure of the vehicle system provided by some embodiments of the present application. Figure 1 As shown, in some embodiments of the present application, the vehicle system 100 includes: First host 110; The second host 120 is communicatively connected to the first host 110; The first host 110 is provided with a Wi-Fi communication module, and the second host 120 is used to perform Wi-Fi data interaction with an external Wi-Fi device through the Wi-Fi communication module of the first host 110 .

[0021] The first host 110 and the second host 120 are in-vehicle hosts. The first host 110 and the second host 120 can be connected to different screens, and different screens can be used by different groups of people. For example, the first host 110 can be connected to the front screen of the vehicle, and the front screen of the vehicle can be used by the front-seat passengers of the vehicle. The second host 120 can be connected to the rear screen of the vehicle, and the rear screen of the vehicle can be used by the rear-seat passengers of the vehicle.

[0022] The Wi-Fi communication module is a hardware component for performing Wi-Fi wireless communication with an external Wi-Fi device, which may include: a Wi-Fi chip and peripheral components of the Wi-Fi chip. The first host 110 is a host provided with a Wi-Fi communication module, which may be one. The second host 120 is a host not provided with a Wi-Fi communication module, which may be one or more. In the case where there are multiple second hosts 120, each second host 120 is communicatively connected to the first host 110. The second host 120 is communicatively connected to the first host 110, including but not limited to: the second host 120 is communicatively connected to the first host 110 via a wired cable; the second host 120 is communicatively connected to the first host 110 via wireless communication.

[0023] An external Wi-Fi device is a Wi-Fi device outside of the vehicle system 100, such as a Wi-Fi hotspot device, a user's mobile phone, a tablet device, etc. There can be one or more external Wi-Fi devices. The types of the multiple external Wi-Fi devices can be different. The external Wi-Fi devices can be directly or indirectly connected to the first host 110 in the vehicle system 100. For example, one external Wi-Fi device can be a Wi-Fi hotspot device, such as a router, which can be directly connected to the first host 110, while another external Wi-Fi device can be a user's mobile phone, which can be indirectly connected to the first host 110 via a Wi-Fi hotspot device. Specifically, the connection with the first host 110 can be connected to the Wi-Fi communication module in the first host 110 via Wi-Fi wireless communication. For example, a Wi-Fi hotspot device can be connected to the Wi-Fi communication module in the first host 110 via Wi-Fi wireless communication, and a mobile phone device can be connected to the Wi-Fi communication module in the first host 110 of the vehicle system 100 via a Wi-Fi hotspot device via Wi-Fi wireless communication.

[0024] In the above embodiment, the second host 120 is communicatively connected with the first host 110, and the first host 110 is provided with a Wi-Fi communication module. The second host 120 performs Wi-Fi data interaction with an external Wi-Fi device through the Wi-Fi communication module of the first host 110. The second host 120 may not be provided with a Wi-Fi communication module, and the hardware cost of the vehicle system can be reduced.

[0025] In the above embodiment, the second host 120 exchanges Wi-Fi data with the external Wi-Fi device through the Wi-Fi communication module of the first host 110. The second host 120 does not need to be provided with a Wi-Fi communication module. The first host 110 can act as a relay node between the second host 120 and the external Wi-Fi device, forwarding data between the second host 120 and the external Wi-Fi device.

[0026] Among them, the current Wi-Fi data frame can be a data frame of a Wi-Fi-based application, and the Wi-Fi-based application is an application implemented based on Wi-Fi wireless communication technology, including but not limited to: Wi-Fi-based screen projection application, Wi-Fi-based Bluetooth phone application, Wi-Fi-based vehicle control application, Wi-Fi-based data sharing application, etc.

[0027] The current Wi-Fi data frame can be sent by any of the following: the host screen of the first host, the second host, or an external Wi-Fi device.

[0028] In some embodiments, the current Wi-Fi data frame may be sent by a host screen of the first host.

[0029] Specifically, the host screen of the first host 110 can send a current Wi-Fi data frame to the first host based on a Wi-Fi application operation performed by a user on the screen. The first host 110 can receive the current Wi-Fi data frame sent by the host screen of the first host. The destination node identifier corresponding to the current Wi-Fi data in the current Wi-Fi data frame sent by the first host screen can be the first host identifier, the destination second host identifier, or the destination external Wi-Fi device identifier. If the destination node identifier corresponding to the current Wi-Fi data is the first host identifier, the first host 110 can process the current Wi-Fi data locally. If the destination node identifier corresponding to the current Wi-Fi data is the destination second host identifier, the first host 110 can forward the current Wi-Fi data to the destination second host based on the destination second host identifier corresponding to the current Wi-Fi data. If the destination node identifier corresponding to the current Wi-Fi data is the destination external Wi-Fi device identifier, the first host 110 can forward the current Wi-Fi data to the destination external Wi-Fi device based on the destination external Wi-Fi device identifier corresponding to the current Wi-Fi data.

[0030] In some implementations, the current Wi-Fi data frame may be sent by the second host 120 .

[0031] Specifically, the second host 120 can send the current Wi-Fi data frame to the first host 110 based on the Wi-Fi application operation performed by the user on the host screen of the second host. The first host 110 can receive the current Wi-Fi data frame sent by the second host 120. The destination node identifier corresponding to the current Wi-Fi data in the current Wi-Fi data frame sent by the second host 120 can be the first host identifier or the destination external Wi-Fi device identifier. In the case where the destination node identifier corresponding to the current Wi-Fi data is the first host identifier, the first host 110 can process the current Wi-Fi data on the first host. In the case where the destination node identifier corresponding to the current Wi-Fi data is the destination external Wi-Fi device identifier, the first host 110 can forward the current Wi-Fi data to the destination external Wi-Fi device according to the destination external Wi-Fi device identifier corresponding to the current Wi-Fi data.

[0032] In some embodiments, the current Wi-Fi data frame may be sent by an external Wi-Fi device.

[0033] Specifically, the external Wi-Fi device can send the current Wi-Fi data frame to the first host 110 based on the Wi-Fi application operation performed by the user on the device. The first host 110 can receive the current Wi-Fi data frame sent by the external Wi-Fi device. The destination node identifier corresponding to the current Wi-Fi data in the current Wi-Fi data frame sent by the external Wi-Fi device can be the first host identifier or the destination second host identifier. In the case where the destination node identifier corresponding to the current Wi-Fi data is the first host identifier, the first host 110 can process the current Wi-Fi data on the first host. In the case where the destination node identifier corresponding to the current Wi-Fi data is the destination second host identifier, the first host 110 can forward the current Wi-Fi data to the destination second host according to the destination second host identifier corresponding to the current Wi-Fi data.

[0034] In the above embodiment, the first host receives the current Wi-Fi data frame sent by the host screen of the first host, the second host, or the external Wi-Fi device, and processes the current Wi-Fi data accordingly based on the destination node identifier corresponding to the current Wi-Fi data in the current Wi-Fi data frame. This allows the user to perform Wi-Fi application operations at any location, such as the host screen of the first host, the host screen of the second host, or the external Wi-Fi device. The location where the user performs Wi-Fi application operations is not limited to a specific location, thereby improving the convenience of the user's Wi-Fi operations.

[0035] In the above embodiment, the destination node identifier corresponding to the current Wi-Fi data is used to identify the destination node of the current Wi-Fi data, which can be obtained in an appropriate manner.

[0036] In some embodiments, the current Wi-Fi data frame is a target format Wi-Fi data frame, and the target format Wi-Fi data frame encapsulates the current Wi-Fi data and a destination node identifier corresponding to the current Wi-Fi data.

[0037] When the current Wi-Fi data frame is a target format Wi-Fi data frame, the first host 110 obtains the current Wi-Fi data and the destination node identifier corresponding to the current Wi-Fi data based on the current Wi-Fi data frame, which may be: The target format Wi-Fi data frame is parsed to obtain current Wi-Fi data and a destination node identifier corresponding to the current Wi-Fi data in the target format Wi-Fi data frame.

[0038] The target format Wi-Fi data frame is a Wi-Fi data frame encapsulating a destination node identifier corresponding to current Wi-Fi data. Figure 2Schematic diagram of the frame structure of Wi-Fi data frame provided in some embodiments of the present application. For example, see Figure 2 , the target format data frame may include: Frame control field Frame Control, destination node identification field FLAG and frame body data Frame Body.

[0039] The Frame Control field is used to control the transmission of the data frame at the TCP / IP layer. It can be, for example, the TCP / IP address of the data frame. The Destination Node Identification field FLAG is used to identify the destination node of the data frame. It can be, for example, the destination host identifier of the data frame or the destination external Wi-Fi device identifier of the data frame. The Frame Body Data is the actual data transmitted in the data frame, that is, the Wi-Fi data frame.

[0040] When the current Wi-Fi data frame is a target format Wi-Fi data frame, the destination node identifier corresponding to the current Wi-Fi data in the current Wi-Fi data frame can be the field value of the destination node identifier field in the current Wi-Fi data frame, that is, the aforementioned FLAG field value, and the current Wi-Fi data in the current Wi-Fi data frame can be the data in the aforementioned frame body data FrameBody. The first host 110 can parse the target format Wi-Fi data frame, remove the Frame Control field in the target format Wi-Fi data frame, obtain the field value of the destination node identifier field FLAG in the target format Wi-Fi data frame and the data in the Frame Body data, thereby obtaining the current Wi-Fi data in the target format Wi-Fi data frame and the destination node identifier corresponding to the current Wi-Fi data.

[0041] In the above embodiment, the target format Wi-Fi data frame may be generated and sent by the second host or the external Wi-Fi device.

[0042] In some embodiments, the second host 120 or external Wi-Fi device is used to: Encapsulating the current Wi-Fi data based on the destination node identifier corresponding to the current Wi-Fi data to obtain the target format Wi-Fi data frame; The target format Wi-Fi data frame is sent to the first host.

[0043] Exemplarily, the current Wi-Fi data frame may be a first Wi-Fi data frame. The first Wi-Fi data frame may be a target format data frame sent by the second host 120. The first Wi-Fi data frame may encapsulate the first Wi-Fi data and a destination node identifier corresponding to the first Wi-Fi data. The first Wi-Fi data may be a data frame that the second host 120 needs to send to an external Wi-Fi device.

[0044] In the above case, the second host 120 is used to: Based on the destination external Wi-Fi device identifier corresponding to the first Wi-Fi data, the first Wi-Fi data is encapsulated to obtain a first Wi-Fi data frame; wherein the destination external Wi-Fi device identifier corresponding to the first Wi-Fi data can be determined according to the destination Wi-Fi device customized by the user; Send the first Wi-Fi data frame to the first host.

[0045] The first host 110 is used for: Receive a first Wi-Fi data frame sent by the second host 120; wherein the first Wi-Fi data frame encapsulates the first Wi-Fi data and the destination external Wi-Fi device identifier corresponding to the first Wi-Fi data; The first Wi-Fi data frame is parsed to obtain the first Wi-Fi data and a destination external Wi-Fi device identifier corresponding to the first Wi-Fi data.

[0046] Exemplarily, the current Wi-Fi data frame may be a second Wi-Fi data frame. The second Wi-Fi data frame may be a target format data frame sent by the external Wi-Fi device. The second Wi-Fi data frame may encapsulate second Wi-Fi data and a destination node identifier corresponding to the second Wi-Fi data. The second Wi-Fi data may be data that the external Wi-Fi device needs to send to the second host 120, and the destination node identifier corresponding to the second Wi-Fi data may be a destination second host identifier.

[0047] In the above scenario, the external Wi-Fi device is used to: The second Wi-Fi data frame is encapsulated based on the destination second host identifier corresponding to the second Wi-Fi data to obtain a second Wi-Fi data frame; the destination node identifier corresponding to the second Wi-Fi data can be determined according to the destination second host specified by the user; The second Wi-Fi data frame is sent to the first host 110 .

[0048] The first host 110 is used for: Receiving, through the Wi-Fi communication module, a second Wi-Fi data frame sent by an external Wi-Fi device; wherein the second Wi-Fi data frame encapsulates the second Wi-Fi data and a destination second host identifier corresponding to the second Wi-Fi data; The second Wi-Fi data frame is parsed to obtain second Wi-Fi data in the second Wi-Fi data frame and a destination second host identifier corresponding to the second Wi-Fi data.

[0049] In the above embodiment, the current Wi-Fi data frame is a target-format Wi-Fi data frame. The second host and the external Wi-Fi device are configured to encapsulate the current Wi-Fi data and the destination node identifier corresponding to the current Wi-Fi data into a target-format Wi-Fi data frame and forward it to the first host. The first host is configured to receive the target-format Wi-Fi data frame, parse the target-format Wi-Fi data frame, and obtain the current Wi-Fi data and the destination node identifier corresponding to the current Wi-Fi data in the target-format Wi-Fi data frame. This allows the user to customize the destination node of the current Wi-Fi data, thereby meeting the different Wi-Fi function requirements of different users and improving the user experience.

[0050] Furthermore, in the above embodiment, the second host and the external Wi-Fi device further encapsulate the Wi-Fi data frame based on the destination node identifier corresponding to the Wi-Fi data to obtain a target format Wi-Fi data frame, and send the target format Wi-Fi data frame to the first host. This also facilitates the first host to perform unified processing on the target format Wi-Fi data frame, reduces processing complexity, and improves the maintainability, scalability, and reliability of the processing.

[0051] In the above embodiment, the current Wi-Fi data frame is a target format Wi-Fi data frame. In some embodiments, the current Wi-Fi data frame may also be a non-target format Wi-Fi data frame, which may encapsulate the current Wi-Fi data but does not encapsulate the destination node identifier corresponding to the current Wi-Fi data.

[0052] In the case where the current Wi-Fi data is non-target format Wi-Fi data, the first host 110 obtains the current Wi-Fi data and the destination node identifier corresponding to the current Wi-Fi data based on the current Wi-Fi data frame, which may be: Parsing the non-target format Wi-Fi data frame to obtain current Wi-Fi data in the non-target format Wi-Fi data frame; Based on the Wi-Fi application to which the current Wi-Fi data belongs, a destination node identifier corresponding to the current Wi-Fi data is determined.

[0053] Wherein, based on the Wi-Fi application to which the current Wi-Fi data belongs, a destination node identifier corresponding to the current Wi-Fi data may be determined by using an appropriate method.

[0054] Exemplarily, the identifier of the node corresponding to the Wi-Fi application to which the current Wi-Fi data belongs may be determined based on the correspondence between the Wi-Fi application and the node, and the node identifier corresponding to the Wi-Fi application may be determined as the destination node identifier corresponding to the current Wi-Fi data.

[0055] The node corresponding to the Wi-Fi application is the node to which the Wi-Fi application belongs, such as the node running the Wi-Fi application, and the node may be, for example, the first host, the second host, or an external Wi-Fi device. In other words, the destination node corresponding to the current Wi-Fi data may be the first host, the second host, or the external Wi-Fi device to which the Wi-Fi application to which the current Wi-Fi data belongs belongs.

[0056] In the above embodiment, the non-target format Wi-Fi data frame may be generated and sent by the second host 120 , or may be generated and sent by an external Wi-Fi device.

[0057] In some embodiments, the second host 120 or external Wi-Fi device is used to: Encapsulate current Wi-Fi data into non-target format Wi-Fi data frames; The non-target format Wi-Fi data frame is sent to the first host.

[0058] For example, the current Wi-Fi data frame may be a third Wi-Fi data frame. The third Wi-Fi data frame may be a non-target format Wi-Fi data frame sent by the second host 120, which may encapsulate the third Wi-Fi data but does not encapsulate the destination node identifier corresponding to the third Wi-Fi data. The third Wi-Fi data may be data that the second host 120 needs to send to the external Wi-Fi device. The destination node identifier corresponding to the third Wi-Fi data may be an external Wi-Fi device identifier.

[0059] In the above case, The second host 120 is used for: encapsulating the third Wi-Fi data into a third Wi-Fi data frame; Send the third Wi-Fi data frame to the second host.

[0060] The first host 110 is used for: receiving a third Wi-Fi data frame sent by the second host 120; wherein the third Wi-Fi data frame encapsulates third Wi-Fi data; Parsing the third Wi-Fi data frame to obtain third Wi-Fi data; A destination external Wi-Fi device identifier corresponding to the third Wi-Fi data is determined based on the Wi-Fi application to which the third Wi-Fi data belongs.

[0061] Exemplarily, the current Wi-Fi data frame may be a fourth Wi-Fi data frame. The fourth Wi-Fi data frame may be a non-target format Wi-Fi data frame sent by the external Wi-Fi device, which may encapsulate the fourth Wi-Fi data but does not encapsulate the destination node identifier corresponding to the fourth Wi-Fi data. The fourth Wi-Fi data may be data that the external Wi-Fi device needs to send to the second host, and the destination node identifier corresponding to the fourth data may be the second host identifier.

[0062] In the above scenario, the external Wi-Fi device is used to: encapsulating the fourth Wi-Fi data into a fourth Wi-Fi data frame; Send the fourth Wi-Fi data frame to the first host.

[0063] The first host 110 is used for: receiving, through the Wi-Fi communication module, a fourth Wi-Fi data frame sent by an external Wi-Fi device; wherein the fourth Wi-Fi data frame encapsulates fourth Wi-Fi data; Parsing the fourth Wi-Fi data frame to obtain fourth Wi-Fi data; A destination second host identifier corresponding to the fourth Wi-Fi data is determined based on the Wi-Fi application to which the fourth Wi-Fi data belongs.

[0075] The current Wi-Fi data frame may be a target format data frame sent by the second host 120, or a non-target format data frame sent by the second host. The first host 110 may receive the current Wi-Fi data frame sent by the second host and, based on the current Wi-Fi data frame, obtain the current Wi-Fi data and the destination node identifier corresponding to the current Wi-Fi data. If the destination node identifier corresponding to the current Wi-Fi data is the identifier of the first host, the current Wi-Fi data is processed locally on the first host.

[0076] In some embodiments, when the current Wi-Fi data frame is a data frame sent by an external Wi-Fi device, the destination node identifier corresponding to the current Wi-Fi data includes: a first host identifier; In the above case, based on the destination node identifier corresponding to the current Wi-Fi data, processing the current Wi-Fi data includes: The current Wi-Fi data is processed on the first host.

[0077] The current Wi-Fi data frame may be a target format data frame sent by an external Wi-Fi device, or a non-target format data frame sent by an external Wi-Fi device. The first host 110 may receive the current Wi-Fi data frame sent by the external Wi-Fi device via a Wi-Fi communication module, and obtain the current Wi-Fi data and the destination node identifier corresponding to the current Wi-Fi data based on the current Wi-Fi data frame. If the destination node identifier corresponding to the current Wi-Fi data is the first host identifier, the first host 110 may process the current Wi-Fi data locally.

[0078] In the above embodiment, the first host processes the current Wi-Fi data based on the destination node identifier corresponding to the current Wi-Fi data. The destination node identifier corresponding to the current Wi-Fi data can be dynamically changed.

[0079] In some embodiments, the first host 110 is configured to: Receive the destination node change instruction of the current Wi-Fi data; According to the destination node change instruction, the destination node identifier of the current Wi-Fi data is changed.

[0080] The destination node change instruction of the current Wi-Fi data may be sent by any of the following according to the user's destination node change operation: the host screen of the first host, the second host, or an external Wi-Fi device.

[0081] Specifically, the destination node change instruction of the current Wi-Fi data can be generated by the host screen of the first host 110 according to the destination node change operation performed by the user on the host screen and sent to the first host 110; it can also be generated by the host screen of the second host 120 according to the destination node change operation performed by the user on the host screen and sent to the second host 120, and then sent by the second host 120 to the first host 110; it can also be generated by an external Wi-Fi device according to the destination node change operation performed by the user on the external Wi-Fi device and sent to the first host 110.

[0082] In the above embodiment, the user is allowed to change the destination node of the current Wi-Fi data at any one of the first host, the second host, and the external Wi-Fi device, thereby improving the convenience of user operation.

[0083] In the above embodiment, the user who performs the destination node change operation does not necessarily need to be the same, and the object of the user operation does not necessarily need to be the same.

[0084] For example, video application A can be installed on second host 1, and video application B can be installed on second host 2. A first user can use external Wi-Fi device 1, such as the first user's mobile phone, to cast video 1 to video application A on second host 1. In response to the first user's casting operation, external Wi-Fi device 1 can obtain the current Wi-Fi data of video 1, encapsulate the current Wi-Fi data of video 1 based on the identifier of second host 1, generate a current Wi-Fi data frame for video 1, and send the current Wi-Fi data frame to the first host. The destination second host identifier corresponding to the current Wi-Fi data in the current Wi-Fi data frame is the identifier of second host 1. The first host can receive the current Wi-Fi data frame via a Wi-Fi communication module, parse the current Wi-Fi data frame, obtain the current Wi-Fi data of video 1 and the identifier of second host 1, and forward the current Wi-Fi data of video 1 to second host 1. Video application A on second host 1 can perform video playback processing based on the current Wi-Fi data of video 1. Based on this video playback processing, the host screen of second host 1 can play video 1.

[0085] If the first user wants to cast video 1 to video application B on second host 2, the first user can perform a destination node change operation on the first host for video 1. In response to the destination node change operation, the first host can change the destination node identifier of the current Wi-Fi data of video 1 from the identifier of second host 1 to the identifier of second host 2. Based on the changed identifier, the first host can forward the current Wi-Fi data of video 1 to second host 2. Video application B on second host 2 can perform video playback processing based on the current Wi-Fi data of video 1. Based on this video playback processing, the host screen of second host 2 can continue to play video 1.

[0086] In the above embodiment, the first host changes the destination node identifier of the current Wi-Fi data according to the destination node change instruction of the current Wi-Fi data, so as to facilitate reuse of subsequent processing of the current Wi-Fi data based on the destination node identifier corresponding to the current Wi-Fi data, thereby reducing processing complexity.

The vehicle-mounted system provided in the embodiments of the present application is further described in conjunction with the interaction process of the vehicle-mounted system.

[0088] In some embodiments of the present application, an external Wi-Fi device can send Wi-Fi data to a second host through the Wi-Fi communication module of the first host in the vehicle system. Figure 3 As shown in the figure, the interaction process of the vehicle system includes: S101: An external Wi-Fi device generates a current Wi-Fi data frame and sends the current Wi-Fi data frame to a first host.

[0089] Among them, when the user specifies the destination node of the current Wi-Fi data, the second host can obtain the destination node identifier of the current Wi-Fi data frame, encapsulate the current Wi-Fi data frame based on the destination node identifier of the current Wi-Fi data frame, and generate the current Wi-Fi data frame in the target format.

[0090] In the case that the user does not specify the destination node of the current Wi-Fi data, the second host may encapsulate the current Wi-Fi data to generate a current Wi-Fi data frame in a non-target format.

[0091] S102: The first host receives a current Wi-Fi data frame sent by an external Wi-Fi device through a Wi-Fi communication module, and obtains current Wi-Fi data and a destination node identifier corresponding to the current Wi-Fi data based on the current Wi-Fi data frame.

[0092] When the current Wi-Fi data frame is a target format data frame, the current Wi-Fi data and the destination node identifier corresponding to the current Wi-Fi data are encapsulated in the current Wi-Fi data frame. The first host can parse the current Wi-Fi data frame to obtain the current Wi-Fi data and the destination node identifier corresponding to the current Wi-Fi data in the current Wi-Fi data frame.

[0093] If the current Wi-Fi data frame is a non-target format data frame, the current Wi-Fi data frame encapsulates the current Wi-Fi data but does not encapsulate the destination node identifier corresponding to the current Wi-Fi data. The first host may parse the current Wi-Fi data frame to obtain the current Wi-Fi data and determine the destination node identifier corresponding to the current Wi-Fi data based on the Wi-Fi application to which the current Wi-Fi data belongs.

[0094] S103: When the destination node identifier corresponding to the current Wi-Fi data is the second host identifier, the first host forwards the current Wi-Fi data to the destination second host based on the destination second host identifier corresponding to the current Wi-Fi data.

[0095] When the destination node identifier corresponding to the current Wi-Fi data is the first host identifier, the first host may process the current Wi-Fi data locally.

[0096] When the destination node identifier corresponding to the current Wi-Fi data is an external Wi-Fi device identifier, the first host may forward the current Wi-Fi data to the destination external Wi-Fi device based on the destination external Wi-Fi device identifier corresponding to the current Wi-Fi data.

[0097] S104: The destination second host processes the current Wi-Fi data.

[0098] During the above process, the user can dynamically change the destination node of the current Wi-Fi data as needed. The user can change the destination node of the current Wi-Fi data on the host screen of the first host, the host screen of the second host, or the external Wi-Fi device, so that the host screen of the first host, the host screen of the second host, or the external Wi-Fi device sends the destination node change instruction of the current Wi-Fi data to the first host.

[0099] When the user performs the above-mentioned target node change operation on the current Wi-Fi data, the above-mentioned process further includes: S105 : The first host receives a destination node change instruction for the current Wi-Fi data, and changes a second destination node for the current Wi-Fi data according to the destination node change instruction for the current Wi-Fi data.

[0100] When a user changes the target node of the current Wi-Fi data on the host screen of the first host, the host screen of the first host may send a target node change instruction for the current Wi-Fi data to the first host. The first host may receive the target node change instruction for the current Wi-Fi data sent by the host screen of the first host.

[0101] When a user changes the target node of the current Wi-Fi data on the host screen of the second host, the host screen of the second host may send a target node change instruction for the current Wi-Fi data to the second host, and the second host may send the target node change instruction for the current Wi-Fi data to the first host. The first host may receive the target node change instruction for the current Wi-Fi data sent by the second host.

[0102] When a user changes the destination node of current Wi-Fi data on the external Wi-Fi device, the external Wi-Fi device may send a destination node change instruction for the current Wi-Fi data to the first host. The first host may receive the destination node change instruction for the current Wi-Fi data sent by the external Wi-Fi device.

[0103] In the case where the destination node identifier corresponding to the current Wi-Fi data is changed, in process S103 , the first host may perform processing based on the changed destination node identifier corresponding to the previous Wi-Fi data.

[0104] Specifically, when the changed destination node identifier corresponding to the current Wi-Fi data is the second host identifier, the first host may forward the current Wi-Fi data to the changed destination second host based on the destination second host identifier currently corresponding to the current Wi-Fi data; when the changed destination node identifier corresponding to the current Wi-Fi data is the first host identifier, the first host may process the current Wi-Fi data locally; when the changed destination node identifier corresponding to the current Wi-Fi data is the external Wi-Fi identifier, the first host may forward the current Wi-Fi data to the destination external Wi-Fi device based on the destination external Wi-Fi identifier currently corresponding to the current Wi-Fi data.

[0105] In some implementations of this application, the second host can send Wi-Fi data to the external Wi-Fi device through the Wi-Fi communication module of the first host in the vehicle system. In the above case, the interaction process of the vehicle system includes: S201: The second host generates a current Wi-Fi data frame and sends the current Wi-Fi data frame to the first host.

[0106] Among them, when the user specifies the destination node of the current Wi-Fi data, the second host can obtain the destination node identifier of the current Wi-Fi data frame, encapsulate the current Wi-Fi data frame based on the destination node identifier of the current Wi-Fi data frame, and generate the current Wi-Fi data frame in the target format.

[0107] In the case that the user does not specify the destination node of the current Wi-Fi data, the second host may encapsulate the current Wi-Fi data to generate a current Wi-Fi data frame in a non-target format.

[0108] S202: The first host obtains current Wi-Fi data and a destination node identifier corresponding to the current Wi-Fi data based on the current Wi-Fi data frame.

The first host can parse the current Wi-Fi data frame to obtain the current Wi-Fi data and the destination node identifier corresponding to the current Wi-Fi data in the current Wi-Fi data frame.

[0110] If the current Wi-Fi data frame is a non-target format data frame, the current Wi-Fi data frame encapsulates the current Wi-Fi data but does not include a destination node identifier corresponding to the current Wi-Fi data. The first host may parse the current Wi-Fi data frame to obtain the current Wi-Fi data and determine the destination node identifier corresponding to the current Wi-Fi data based on the Wi-Fi application to which the current Wi-Fi data belongs.

[0111] S203: When the destination node identifier corresponding to the current Wi-Fi data is an external Wi-Fi device identifier, the first host forwards the current Wi-Fi data to the destination external Wi-Fi device based on the destination external Wi-Fi device identifier corresponding to the current Wi-Fi data.

[0112] The first host may directly forward the current Wi-Fi data to the destination external Wi-Fi device, or may encapsulate the current Wi-Fi data based on the destination node identifier corresponding to the current Wi-Fi data and forward the encapsulated data to the destination external Wi-Fi device.

[0113] When the destination node identifier corresponding to the current Wi-Fi data is the first host identifier, the first host may process the current Wi-Fi data locally.

[0114] When the destination node identifier corresponding to the current Wi-Fi data is the second host identifier, the first host may forward the current Wi-Fi data to the destination second host based on the destination second host identifier corresponding to the current Wi-Fi data.

[0115] S204: The destination external Wi-Fi device processes the current Wi-Fi device.

[0116] During the above process, the user can change the destination node of the current Wi-Fi data on the host screen of the first host, the host screen of the second host, or the external Wi-Fi device, thereby causing the host screen of the first host, the host screen of the second host, or the external Wi-Fi device to send a destination node change instruction for the current Wi-Fi data to the first host. The first host can receive the destination node change instruction for the current Wi-Fi data and change the destination node identifier corresponding to the current data according to the destination node change instruction for the current data.

[0117] When the user changes the target node of the current Wi-Fi data, the above process also includes the following processing: S205 : The first host receives a destination node change instruction for the current Wi-Fi data, and changes a second destination node for the current Wi-Fi data according to the destination node change instruction for the current Wi-Fi data.

[0118] When a user changes the target node of the current Wi-Fi data on the host screen of the first host, the host screen of the first host may send a target node change instruction for the current Wi-Fi data to the first host. The first host may receive the target node change instruction for the current Wi-Fi data sent by the host screen of the first host.

[0121] In the case where the destination node identifier corresponding to the current Wi-Fi data is changed, in process S203 , the first host may perform processing based on the changed destination node identifier corresponding to the previous Wi-Fi data.

[0122] Specifically, when the changed destination node identifier corresponding to the current Wi-Fi data is the second host identifier, the first host may forward the current Wi-Fi data to the changed destination second host based on the destination second host identifier currently corresponding to the current Wi-Fi data; when the changed destination node identifier corresponding to the current Wi-Fi data is the first host identifier, the first host may process the current Wi-Fi data locally; when the changed destination node identifier corresponding to the current Wi-Fi data is the external Wi-Fi identifier, the first host may forward the current Wi-Fi data to the destination external Wi-Fi device based on the destination external Wi-Fi identifier currently corresponding to the current Wi-Fi data.
