[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0027] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0028] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0029] The following explains the application scenarios of the communication method of the vehicle-mounted terminal provided in the embodiments of the present application.

[0030] Figure 1 This is a schematic diagram of the application scenario provided in the embodiment of this application, please refer to Figure 1 , the scenario may include: a mobile terminal 110 and a vehicle terminal 120 , wherein the mobile terminal 110 may be physically connected to the vehicle terminal 120 .

[0031] It should be noted that the mobile terminal 110 may include but is not limited to a mobile phone, a wearable device (such as a smart watch, a smart bracelet, smart glasses, etc.), a tablet computer, a laptop computer, a PC (Personal Computer), etc. The functions implemented by the method can be implemented by calling a program code by a processor in the mobile terminal. Of course, the program code can be stored in a computer storage medium. It can be seen that the mobile terminal at least includes a processor and a storage medium.

[0032] The vehicle-mounted terminal 120 may be a terminal device installed in the vehicle, for example, a vehicle computer or other vehicle-mounted entertainment equipment, which is not specifically limited here.

[0033] Optionally, the mobile terminal 110 may be physically connected to the vehicle-mounted terminal 120 , for example, via a Universal Serial Bus (USB).

[0034] It should be noted that in the actual implementation process, the mobile terminal 110 can communicate with the vehicle-mounted terminal 120 through a physical connection, and various functions can be realized through this communication method, such as: screen projection, file downloading, application transmission and other functions.

[0035] For example, the vehicle-mounted terminal 120 may have a display, and the mobile terminal 110 may enable the display of the vehicle-mounted terminal 120 to display content that can be played on the mobile terminal, such as video files, video calls, etc., through a physical connection, without specific limitation.

[0036] When the mobile terminal 110 establishes a physical connection with the vehicle-mounted terminal 120 , the mobile terminal 110 may adjust the configuration of the physical interface, for example, may set appropriate connection configuration parameters, so as to make the data transmitted by the physical connection more stable.

[0037] It should be noted that in the process of establishing a physical connection between the vehicle-mounted terminal 120 and the mobile terminal 110, due to the differences in materials, circuit structures, etc. of vehicle-mounted terminals produced by different manufacturers, this will lead to the physical interfaces of the vehicle-mounted terminals being non-uniform. The connection configuration parameters that need to be adapted when the same mobile terminal 110 establishes a physical connection with different vehicle-mounted terminals 120 are also different.

[0038] In the related art, the mobile terminal 110 may adopt fixed connection configuration parameters, which may not be applicable to different models of vehicle-mounted terminals 120, resulting in lower stability of data transmission; alternatively, the mobile terminal 110 may also adopt a method of continuously adjusting the connection configuration parameters to adapt to different vehicle-mounted terminals 120, which will cause the mobile terminal 110 to consume a lot of time to match the connection configuration parameters, thereby failing to quickly achieve stable communication between the mobile terminal 110 and the vehicle-mounted terminal 120.

[0039] In order to solve the above-mentioned problems existing in the related art, a communication method for a vehicle-mounted terminal is provided in an embodiment of the present application. The implementation process of the communication method for the vehicle-mounted terminal provided in the embodiment of the present application is explained below.

[0040] Figure 2 This is a flow chart of the communication method of the vehicle terminal provided in the embodiment of the present application, please refer to Figure 2 , a communication method of a vehicle terminal, comprising:

[0041] S210: Acquire identification information of the target vehicle-mounted terminal when physically connected to the target vehicle-mounted terminal.

[0042] It should be noted that the execution subject of the method may be the above-mentioned mobile terminal, and the target vehicle terminal may be a vehicle terminal that needs to establish a physical connection with the mobile terminal, for example, Figure 1 The vehicle terminal shown in .

[0043] Optionally, the mobile terminal may establish a physical connection with the target vehicle-mounted terminal, wherein the physical connection may be, for example, the USB connection explained above.

[0044] For example: the physical interface of the mobile terminal can be connected to the physical interface of the vehicle terminal through a physical connection, wherein the physical connection can be a USB connection and the physical interface can be a USB interface.

[0045] It should be noted that the identification information of the target vehicle-mounted terminal can be an identification recording the model of the target vehicle-mounted terminal. For example, vehicle-mounted terminals of the same model produced by the same manufacturer can have the same identification information; correspondingly, vehicle-mounted terminals produced by different manufacturers and vehicle-mounted terminals of different models have different corresponding identification information.

[0046] The model of the vehicle-mounted terminal may be a model defined by a manufacturer. For vehicle-mounted terminals of the same model, their hardware structure, software logic, etc. are the same, and the identification information of such vehicle-mounted terminals may be the same.

[0047] In one embodiment, after the target vehicle terminal establishes a physical connection with the mobile terminal, the mobile terminal can actively obtain the identification information of the target vehicle terminal, or the target vehicle terminal can actively send the identification information to the mobile terminal. There is no specific limitation here, and one of the transmission methods can be selected according to actual needs.

[0048] In one embodiment, obtaining identification information of the target vehicle-mounted terminal includes: obtaining identification information of the target vehicle-mounted terminal through a physical connection.

[0049] It should be noted that after the mobile terminal establishes a physical connection with the target vehicle terminal, the identification information of the target vehicle terminal can be obtained through the physical connection. For example, the identification information can be sent from the target vehicle terminal to the mobile terminal through a USB connection.

[0050] Optionally, in addition to establishing a physical connection between the mobile terminal and the target vehicle-mounted terminal, other wireless connections can also be established, such as: Bluetooth connection, WiFi connection, and other types of connection methods. In addition to allowing the mobile terminal to obtain the identification information of the target vehicle-mounted terminal through a physical connection, the mobile terminal can also obtain the identification information of the target vehicle-mounted terminal through other wireless connection methods.

[0051] S220: Communicate with the target vehicle-mounted terminal using the target connection configuration parameters corresponding to the identification information of the target vehicle-mounted terminal.

[0052] It should be noted that after the mobile terminal obtains the identification information of the target vehicle-mounted terminal, it can determine the target connection parameter corresponding to the identification information of the target vehicle-mounted terminal.

[0053] The target connection configuration parameters are used to characterize the communication quality of the physical connection.

[0054] Optionally, the target connection configuration parameters may include: receiving sensitivity, and / or signal strength of the transmission signal.

[0055] It should be noted that the receiving sensitivity may be, for example, the driving RX sensitivity (Rx Sensitivity), which may be an important parameter in the field of wireless communications, and represents the minimum signal strength that a receiver can identify without exceeding a certain bit error rate.

[0056] Optionally, receiving sensitivity is a key indicator for measuring the performance of wireless receiving equipment, which directly affects the performance and communication reliability of the communication system. By adjusting the receiving sensitivity, more stable data transmission can be achieved between the mobile terminal and the vehicle-mounted terminal.

[0057] In an embodiment, in addition to using the receiving sensitivity as the target connection configuration parameter, the signal strength of the transmission signal may also be used as the target connection configuration parameter.

[0058] For example: if the signal strength of the transmission signal is within the preset target range, stable signal transmission can be achieved; if the signal strength of the transmission signal exceeds the target range or does not reach the target range, problems such as packet loss may exist during the signal transmission process, resulting in unstable signal transmission.

[0059] In practical applications, receiving sensitivity may be used as the target connection configuration parameter, or the signal strength of the transmission signal may be used as the target connection configuration parameter, or both may be used as the target connection configuration parameter, without specific limitation herein.

[0060] It should be noted that the correspondence between the identification information of the target vehicle terminal and the target connection configuration parameters can be pre-stored in the mobile terminal. After obtaining the identification information of the target vehicle terminal, the target connection configuration parameters corresponding to the identification information of the target vehicle terminal can be determined based on the correspondence.

[0061] Optionally, the above correspondence relationship may be stored in the mobile terminal itself or in other devices. If it is stored in other devices, the mobile terminal may communicate with the other devices to obtain the correspondence relationship.

[0062] After determining the target connection configuration parameters corresponding to the identification information of the target vehicle-mounted terminal in the above manner, the mobile terminal can perform data transmission with the target vehicle-mounted terminal according to the target connection configuration parameters.

[0063] For example, the mobile terminal can configure the parameters of the physical interface according to the target connection configuration parameters, for example, adjusting the RX sensitivity of the physical interface, and then realizing data transmission between the mobile terminal and the target vehicle terminal under the RX sensitivity. Alternatively, adjusting the signal strength of the transmission signal of the physical interface, and then performing data transmission according to the adjusted signal strength.

[0064] In the communication method of the vehicle terminal provided in the embodiment of the present application, the identification information of the target vehicle terminal can be obtained when the target vehicle terminal is physically connected; the target connection configuration parameters corresponding to the identification information of the target vehicle terminal are used to communicate with the target vehicle terminal, wherein the target connection configuration parameters are used to characterize the communication quality of the physical connection, and the corresponding target connection configuration parameters can be determined by the identification information of the target vehicle terminal, so that the mobile terminal can communicate with the target vehicle terminal according to the target connection configuration parameters. In the process of message transmission between the mobile terminal and the vehicle terminal through the physical connection, the stability of the message transmission can be improved, and the target connection configuration parameters are determined according to the identification information of the target vehicle terminal, so that stable communication between the mobile terminal and the vehicle terminal can be achieved more quickly, and it can be adapted to different types of vehicle terminals.

[0065] It should be noted that, since the corresponding relationship between the identification information of the target vehicle terminal and the target connection configuration parameters can be pre-set in the mobile terminal or other devices that can communicate with the mobile terminal, the target connection configuration parameters required for the target vehicle terminal can be directly determined after the identification information of the target vehicle terminal is obtained. Therefore, the communication between the mobile terminal and the vehicle terminal can be achieved more quickly. In addition, according to the target connection configuration parameters, the communication between the mobile terminal and the vehicle terminal can be made more stable, so the stable communication between the mobile terminal and the vehicle terminal can be achieved more quickly. For different types of vehicle terminals, the corresponding identification information is also different, and correspondingly there are different target connection configuration parameters. In this way, different types of vehicle terminals can be adapted.

[0066] The following is an explanation of one feasible implementation process of determining the target connection configuration parameters in an embodiment of the present application.

[0067] Figure 3 For a logical diagram of determining target connection configuration parameters provided in an embodiment of the present application, please refer to Figure 3 Before communicating with the target vehicle-mounted terminal using the target connection configuration parameters corresponding to the identification information of the target vehicle-mounted terminal, the method further includes:

[0068] S310: Obtain a parameter configuration table.

[0069] It should be noted that the parameter configuration table may be a mapping table stored in the mobile terminal, and the mapping table may record at least one set of mapping relationships.

[0070] The parameter configuration table includes a mapping relationship between identification information of at least one vehicle-mounted terminal and preset connection configuration parameters.

[0071] It should be noted that the parameter configuration table may be a table pre-configured in the mobile terminal before leaving the factory, or may be a table sent to the mobile terminal by other devices after the mobile terminal leaves the factory, and no specific limitation is made here.

[0072] The table can be a fixed table or an updateable table. For example, for a fixed table, each set of mapping relationships is fixed; for an updateable table, each set of mapping relationships can be modified, and new mapping relationships can be added or some existing mapping relationships can be deleted.

[0073] The parameter configuration table may be shown in Table 1, for example:

[0074] Table 1

[0075] Identification information of vehicle terminal Connection configuration parameters Identification information 1 Connection configuration parameters 1 Identification information 2 Connection configuration parameters 2 … … Identification information Connection configuration parameter N

[0076] Please refer to Table 1. The parameter configuration table may have multiple groups of mapping relationships, and each group of mapping relationships includes identification information of an in-vehicle terminal and connection configuration parameters corresponding to the identification information of the in-vehicle terminal.

[0077] It should be noted that the parameter configuration table can be stored in the mobile terminal in the form of a table in the manner of Table 1 above, or it can be stored in the form of multiple scattered mapping relationships. There is no specific limitation here, and one of the storage methods can be selected according to actual needs.

[0078] In one embodiment, the above-mentioned mapping relationship may be connection configuration parameters determined during the testing of various types of vehicle-mounted terminals during the testing phase before leaving the factory. For each type of mobile terminal, when the mobile terminal is physically connected to a vehicle-mounted terminal with the same identification information, the corresponding connection configuration parameters in the mapping relationship may be used to realize physical communication between the two devices.

[0079] When the identification information of the target vehicle-mounted terminal exists in the parameter configuration table, S320: acquiring the target connection configuration parameters from the parameter configuration table.

[0080] It should be noted that after obtaining the identification information of the target vehicle terminal, it can be determined whether the identification information of the target vehicle terminal exists in the parameter configuration table. If so, the target connection configuration parameters can be determined from the parameter configuration table.

[0081] Among them, the target connection configuration parameters can be the connection configuration parameters corresponding to the identification information of the target vehicle terminal in the above parameter configuration table. For example: please refer to Table 1. If the identification information of the target vehicle terminal is identification information 2, then connection configuration parameter 2 is the target connection configuration parameter.

[0082] After the target connection configuration parameters are determined from the parameter configuration table in the above manner, the mobile terminal can communicate with the target vehicle-mounted terminal through a physical connection according to the target connection configuration parameters.

[0083] In the communication method of the vehicle terminal provided in the embodiment of the present application, a parameter configuration table can be obtained; when the identification information of the target vehicle terminal exists in the parameter configuration table, the target connection configuration parameters are obtained from the parameter configuration table. Among them, the target connection configuration parameters corresponding to the identification information of the target vehicle terminal can be determined more quickly and accurately through the parameter configuration table, so as to more quickly establish a stable physical connection with the target vehicle terminal based on the target connection configuration parameters, and realize data interaction of the physical connection.

[0084] It should be noted that the above embodiment explains the steps performed by the mobile terminal when the identification information of the target vehicle terminal exists in the parameter configuration table. In the actual implementation process, there may also be a situation where the identification information of the target vehicle terminal does not exist in the parameter configuration table. The steps performed by the mobile terminal in this case are explained below:

[0085] In one embodiment, the mobile terminal is in communication connection with the server, and when the identification information of the target vehicle-mounted terminal does not exist in the parameter configuration table, the method further includes:

[0086] S330: Send a parameter acquisition request to the server, so that the server sends the target connection configuration parameters corresponding to the identification information of the target vehicle terminal according to the parameter acquisition request.

[0087] It should be noted that the server may be a cloud server that performs data interaction with the mobile terminal. The server may store mapping relationships between identification information of multiple target vehicle-mounted terminals and target connection configuration parameters, and these mapping relationships are updateable.

[0088] For example, before a new type of vehicle-mounted terminal leaves the factory, the most suitable connection configuration parameters corresponding to the vehicle-mounted terminal can be determined by testing, and then a mapping relationship between the identification information of the vehicle-mounted terminal and its corresponding connection configuration parameters can be established on the server side.

[0089] It should be noted that the parameter configuration table can also be stored in the server side. Different from the parameter configuration table in the mobile terminal, there can be multiple parameter configuration tables in the server side. Each parameter configuration table can represent a parameter configuration table corresponding to a type of mobile terminal. There may be differences in the parameter configuration tables corresponding to different types of terminal devices. For example: for the same vehicle terminal, after the vehicle terminal establishes a physical connection with different types of mobile terminals, there may be certain differences in the connection configuration parameters used. The parameter configuration table of each type of mobile terminal can be recorded in the server side, that is, it can include multiple sets of mapping relationships for each type of mobile terminal.

[0090] Among them, the parameter configuration table stored in the server can be updated in real time. For example, the server can communicate with the test equipment of multiple vehicle terminal manufacturers. After obtaining the corresponding test data, the identification information of the vehicle terminal obtained from the test and the corresponding connection configuration parameters can be sent to the server, so that the server can update the corresponding parameter configuration table.

[0091] In one embodiment, if the identification information of the target vehicle terminal does not exist in the parameter configuration table of the mobile terminal, the target connection configuration parameters corresponding to the identification information of the target vehicle terminal can be obtained from the server. For example, a parameter acquisition request can be sent to the server to obtain the target connection configuration parameters.

[0092] The parameter acquisition request includes identification information of the target vehicle-mounted terminal.

[0093] After the mobile terminal sends the parameter acquisition request to the server, the server may query from multiple parameter configuration tables according to the identification information of the target vehicle-mounted terminal in the parameter acquisition request.

[0094] In one of the embodiments, the server can find multiple target connection configuration parameters corresponding to the identification information of the target vehicle-mounted terminal from multiple parameter configuration tables stored in itself, and send these target connection configuration parameters to the mobile terminal. These sent target connection configuration parameters can carry the type of mobile terminal corresponding to the parameter configuration table in which they are located. It has been explained above that each parameter configuration table in the server can be a parameter configuration table for a type of mobile terminal.

[0095] After the above-mentioned multiple target connection configuration parameters are sent to the mobile terminal, the mobile terminal may determine one of the target connection configuration parameters it needs according to its own type.

[0096] Alternatively, in another embodiment, the parameter acquisition request may also include identification information of the mobile terminal. After the server obtains the parameter acquisition request, it can first determine the parameter configuration table corresponding to the type of the mobile terminal from multiple parameter configuration tables based on the identification information of the mobile terminal, and then determine the target connection configuration parameters from the parameter configuration table based on the identification information of the target vehicle-mounted terminal, and send the target connection configuration parameters to the mobile terminal.

[0097] It should be noted that in the actual implementation process, both of the above implementation modes are acceptable, and the content included in the parameter acquisition request can be set according to actual needs.

[0098] In one embodiment, the server may send a separate target connection configuration parameter to the mobile terminal, or may send a corresponding parameter configuration table to the mobile terminal, so that the mobile terminal updates its own parameter configuration table to obtain the target connection configuration parameter.

[0099] In the communication method of the vehicle terminal provided in the embodiment of the present application, when the identification information of the target vehicle terminal does not exist in the parameter configuration table, a parameter acquisition request can be sent to the server, so that the server sends the target connection configuration parameter corresponding to the identification information of the target vehicle terminal according to the parameter acquisition request. Among them, when the target connection configuration parameter corresponding to the identification information of the target vehicle terminal does not exist in the mobile terminal, the target connection configuration parameter can be obtained from the server, so that the mobile terminal can determine the target connection configuration parameter in time, and realize stable communication with the vehicle terminal more efficiently and quickly.

[0100] In order to more clearly explain the data interaction between the server and the mobile terminal, the interaction process between the server and the mobile terminal provided in the embodiment of the present application is explained below.

[0101] Figure 4 This is a schematic diagram of one of the interactions between the server and the mobile terminal provided in the embodiment of the present application. Please refer to Figure 4 , the method comprising:

[0102] S410: When the identification information of the target vehicle-mounted terminal does not exist in the parameter configuration table, the mobile terminal sends a parameter acquisition request to the server.

[0103] S420: The server determines the target connection configuration parameters according to the parameter acquisition request.

[0104] S430: The server sends the target connection configuration parameters to the mobile terminal.

[0105] S440: The mobile terminal communicates with the target vehicle-mounted terminal according to the target connection configuration parameters.

[0106] Figure 4 The interaction process shown in is an implementation process in which the server provides the target connection configuration parameters to the mobile terminal.

[0107] It should be noted that, in addition to providing target connection configuration parameters, the server may also provide a parameter configuration table to the mobile terminal, thereby updating the parameter configuration table of the mobile terminal.

[0108] Figure 5 Another interactive diagram of the server and the mobile terminal provided in the embodiment of the present application is shown in FIG. Figure 5 , the method comprising:

[0109] S510: When the identification information of the target vehicle-mounted terminal does not exist in the parameter configuration table, the mobile terminal sends a parameter acquisition request to the server.

[0110] S520: The server determines an updated parameter configuration table according to the parameter acquisition request.

[0111] S530: The server sends the updated parameter configuration table to the mobile terminal.

[0112] S540: The mobile terminal determines the target connection configuration parameters according to the updated parameter configuration table, and communicates with the target vehicle-mounted terminal according to the target connection configuration parameters.

[0113] Figure 5 The interaction process shown in is an implementation process in which the server provides the mobile terminal with an updated parameter configuration table.

[0114] It should be noted that, in the above embodiment, the parameter configuration table of the mobile terminal can be updated, and can be updated according to the updated parameter configuration table sent by the server.

[0115] Multiple parameter configuration tables can be pre-stored in the server, and the corresponding parameter configuration table can be determined according to the identification of the mobile terminal. Since the parameter configuration table of the server is updated in real time, the parameter configuration table of the server is the latest parameter configuration table. The parameter configuration table can be sent to the mobile terminal as an updated parameter configuration table, and then the mobile terminal can implement the update of the parameter configuration table. After the update is completed, the mobile terminal can implement the update of the target connection configuration parameters according to the updated parameter configuration table transmitted by the server.

[0116] It should be noted that Figure 4 as well as Figure 5The steps of determining the target connection configuration parameters shown in the figure are all parameter acquisition requests actively initiated by the mobile terminal. In the actual implementation process, the server can also actively send an updated parameter configuration table to each mobile terminal at a preset time, thereby updating the parameter configuration table of the mobile terminal.

[0117] In one embodiment, the parameter configuration table is updated at a preset time interval.

[0118] For example: the server can send an updated parameter configuration table to each mobile terminal every 5 days, so that the parameter configuration table of the mobile terminal is updated in time, thereby increasing the possibility of determining the target connection configuration parameters from the parameter configuration table of the mobile terminal in the process of determining the target connection configuration parameters.

[0119] In an embodiment of the present application, by timely updating the parameter configuration table, such as updating the parameter configuration table at a preset time interval, the accuracy and comprehensiveness of the mapping relationship included in the parameter configuration table can be improved, thereby increasing the possibility of determining the target connection configuration parameters from the parameter configuration table of the mobile terminal.

[0120] In one embodiment, in order to update the parameter configuration table in each mobile terminal, a plurality of parameter configuration tables may be provided in the server.

[0121] Figure 6 This is a schematic diagram of multiple parameter configuration tables in the server provided in the embodiment of the present application, please refer to Figure 6 , Figure 6 The multiple parameter configuration tables shown in are all parameter configuration tables set in the server, and each parameter configuration table can be a parameter configuration table corresponding to a type of mobile terminal. For example, an Android phone can correspond to a parameter configuration table, an IOS phone can correspond to a parameter configuration table, an Android tablet can correspond to a parameter configuration table, etc. There is no specific limitation here, and different parameter configuration tables can be set according to different types of mobile terminals.

[0122] Different parameter configuration tables may have different mapping relationships. For example, the corresponding connection configuration parameters of the identification information of the same vehicle-mounted terminal may be different in different parameter configuration tables.

[0123] In the process of updating the parameter configuration table in each mobile terminal, one of the parameter configuration tables corresponding to the mobile terminal can be determined based on the mobile terminal identifier sent by the mobile terminal, and then the parameter configuration table can be sent to the mobile terminal for updating.

[0124] It should be noted that in the process of updating the parameter configuration table, if the server sends a new parameter configuration table, the parameter configuration table in the mobile terminal can be directly replaced to achieve the update of the parameter configuration table; if the server sends one or more groups of mapping relationships, the mobile terminal can add these mapping relationships to the parameter configuration table to achieve the update of the parameter configuration table.

[0125] Among them, in order to ensure the normal update of the parameter configuration table, a big data interface, a preloading interface and the like can be reserved to implement the update of the parameter configuration table. Among them, the big data interface is the interface for connecting to the server, and the preloading interface can be an interface for loading the mapping relationship sent by the server. The update of the parameter configuration table can be implemented through the above methods.

[0126] The following explains the implementation process of pre-configuration of the physical interface of the mobile terminal provided in the embodiment of the present application.

[0127] Figure 7 For a flow chart of pre-configuration of a physical interface provided in an embodiment of the present application, please refer to Figure 7 The mobile terminal establishes a physical connection with the target vehicle-mounted terminal through the physical interface. Before the physical connection with the target vehicle-mounted terminal, the method further includes:

[0128] S710: Obtain identification information of a pre-selected vehicle-mounted terminal through Bluetooth recognition.

[0129] It should be noted that, in addition to physical connection through a physical interface, the mobile terminal and the vehicle-mounted terminal may also communicate in a wireless connection manner, for example, via a Bluetooth connection.

[0130] Since Bluetooth connection is suitable for transmitting smaller amounts of data, it is not suitable for scenarios such as screen projection and file downloading, but it can be used to determine the identification information of the vehicle terminal in advance.

[0131] In actual application scenarios, after a user carries a mobile terminal into a vehicle, the mobile terminal can establish a Bluetooth communication connection with the vehicle-mounted terminal. In this case, the mobile terminal can first obtain identification information of the pre-selected vehicle-mounted terminal through Bluetooth recognition.

[0132] Among them, the pre-selected vehicle-mounted terminal can be one of the multiple vehicle-mounted terminals of the vehicle. There can be multiple vehicle-mounted terminals in the vehicle. The vehicle-mounted terminal that is physically connected to the mobile terminal is the above-mentioned target vehicle-mounted terminal. The pre-selected vehicle-mounted terminal can be any one of the multiple vehicle-mounted terminals, which can be the above-mentioned target vehicle-mounted terminal or other vehicle-mounted terminals. No specific restrictions are made here.

[0133] In one embodiment, the identification information of the vehicle-mounted terminal can be directly obtained through a Bluetooth connection, or the vehicle information can be obtained, and then the identification information of the vehicle-mounted terminal can be determined based on the vehicle information. In the actual implementation process, any one of the above two methods can be used to determine the identification information of the pre-selected vehicle-mounted terminal.

[0134] S720: Preconfigure the physical interface of the mobile terminal according to the connection configuration parameters corresponding to the identification information of the preselected vehicle-mounted terminal.

[0135] It should be noted that after the identification information of the pre-selected vehicle-mounted terminal is determined by Bluetooth recognition, the connection configuration parameters corresponding to the identification information of the pre-selected vehicle-mounted terminal can be determined according to the above parameter configuration table. The determination process can be performed according to Figure 3 According to the process shown in , the connection configuration parameters corresponding to the identification information of the pre-selected vehicle-mounted terminal can be obtained, and the physical interface of the mobile terminal can be pre-configured based on the connection configuration parameters.

[0136] Pre-configuration refers to configuring parameters of the physical interface before the physical interface establishes a communication connection. For example, the receiving sensitivity of the physical interface or the signal strength of the transmission signal can be adjusted, thereby realizing pre-configuration of the physical interface.

[0137] Optionally, the physical interface may be a USB interface of the mobile terminal.

[0138] In the communication method of the vehicle terminal provided in the embodiment of the present application, the identification information of the pre-selected vehicle terminal can be obtained through Bluetooth recognition; the physical interface of the mobile terminal is pre-configured according to the connection configuration parameters corresponding to the identification information of the pre-selected vehicle terminal. Among them, the connection configuration corresponding to the identification information of the pre-selected vehicle terminal can be determined through Bluetooth recognition to pre-configure the physical interface of the mobile terminal in advance, thereby more quickly establishing a physical connection between the mobile terminal and the vehicle terminal.

[0139] In one embodiment, the target connection configuration parameters corresponding to the identification information of the target vehicle terminal are used to communicate with the target vehicle terminal, including: when the identification information of the pre-selected vehicle terminal is the same as the identification information of the target vehicle terminal, communicating with the target vehicle terminal based on the pre-configured physical interface.

[0140] It should be noted that after the physical interface of the mobile terminal is preconfigured based on the connection configuration parameters corresponding to the identification information of the preselected vehicle terminal, if the mobile terminal establishes a physical connection with the vehicle terminal, it can be determined whether the identification information of the preselected vehicle terminal is the same as the identification information of the target vehicle terminal.

[0141] If they are the same, it can be determined that the pre-selected vehicle terminal is the target vehicle terminal, and the target vehicle terminal can be communicated directly through the pre-configured physical interface; if they are different, it can be determined that the pre-selected vehicle terminal is not the target vehicle terminal, and it is necessary to re-configure it according to Figure 2 According to the steps shown in , the physical interface is configured according to the target connection configuration parameters corresponding to the target vehicle terminal, thereby realizing communication.

[0142] In the communication method of the vehicle terminal provided in the embodiment of the present application, when the identification information of the pre-selected vehicle terminal is the same as the identification information of the target vehicle terminal, the communication with the target vehicle terminal can be based on the pre-configured physical interface. Wherein, when the identification information of the pre-selected vehicle terminal is the same as the identification information of the target vehicle terminal, it can be determined that the target vehicle terminal is the pre-selected vehicle terminal, and there is no need to re-determine the target connection configuration parameters. The pre-configured physical interface is the physical interface configured using the target connection configuration parameters, and the communication between the mobile terminal and the target vehicle terminal can be realized more quickly based on the pre-configured physical interface.

[0143] It should be noted that, since a vehicle may include multiple vehicle-mounted terminals, a pre-selected vehicle-mounted terminal may be selected from the multiple vehicle-mounted terminals.

[0144] In one embodiment, obtaining identification information of a preselected vehicle-mounted terminal through Bluetooth identification includes: obtaining identification information of at least one vehicle-mounted terminal through Bluetooth identification; and determining identification information of the preselected vehicle-mounted terminal from identification information of at least one vehicle-mounted terminal in response to a selection operation.

[0145] It should be noted that, since there may be multiple vehicle-mounted terminals in a vehicle, after the mobile terminal turns on Bluetooth identification, the identification information of the multiple vehicle-mounted terminals may be obtained.

[0146] The identification information of these vehicle-mounted terminals can be displayed on the display of the mobile terminal, wherein the identification information can be displayed, or the identification information can be converted into corresponding text, numbers, images and other content for display, without specific limitation here.

[0147] The following is an example to explain the content displayed in the selection interface of the mobile terminal provided in the embodiment of the present application.

[0148] Figure 8 For a schematic diagram of the interface for selecting a mobile terminal provided in the embodiment of the present application, please refer to Figure 8 , Figure 8 The display interface shown in is the content displayed on the display of the mobile terminal. In this display interface, multiple vehicle-mounted terminals recognized by Bluetooth can be displayed, such as Figure 8In-car entertainment equipment, car speakers and car navigation systems, etc.

[0149] For the above-mentioned multiple vehicle-mounted terminals, one can be determined as the above-mentioned pre-selected vehicle-mounted terminal. In response to the user's selection operation, the pre-selected vehicle-mounted terminal can be determined from multiple vehicle-mounted terminals, thereby realizing the determination of the identification information of the pre-selected vehicle-mounted terminal from the identification information of at least one vehicle-mounted terminal.

[0150] The identification information of the pre-selected vehicle-mounted terminal can be obtained in the above manner, and then the pre-configuration of the physical interface of the mobile terminal can be implemented based on the connection configuration parameters corresponding to the identification information of the pre-selected vehicle-mounted terminal.

[0151] In the communication method of the vehicle terminal provided in the embodiment of the present application, the identification information of at least one vehicle terminal can be obtained through Bluetooth recognition; in response to the selection operation, the identification information of the pre-selected vehicle terminal is determined from the identification information of at least one vehicle terminal. Among them, the pre-selected vehicle terminal can be quickly determined from multiple vehicle terminals by selection, so that the identification information of the pre-selected vehicle terminal can be obtained more efficiently and quickly.

[0152] It should be understood that, although the steps in the above-mentioned flowcharts are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the above-mentioned flowcharts may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the sub-steps or stages of other steps.
