[0037] With the development of the Internet, the Internet of Vehicles has also been rapidly popularized and widely used in vehicles. It effectively connects various data devices and provides vehicles with reliable basic data service connection and interaction capabilities. Mobile terminals, as high-frequency devices used by users when they are out of the vehicle environment, have also brought great convenience to users. Whether it is the Internet of Vehicles or mobile terminals, users mainly use audio, video, map navigation and other related functions. After getting in the car, users often continue to operate through mobile terminals in the vehicle environment because they are accustomed to the operation of mobile terminals, which brings certain risks to driving safety.

[0038] In order to solve the problems of the prior art, the embodiments of the present application provide a data synchronization method, device, equipment, medium and product.

[0039] first, Figure 1 A framework diagram of a data synchronization system applicable to an embodiment of the present application is shown.

[0040] like Figure 1 As shown, the data synchronization system 100 may include: a vehicle-mounted terminal 101 and a mobile terminal 102 .

[0041] The vehicle-mounted terminal 101 can be a carrier applied to a vehicle and has information processing and computing functions. The vehicle-mounted terminal 101 also has good vehicle network data communication capabilities.

[0042] The mobile terminal 102 may be a computer device used on the move, and its mobility is mainly reflected in its mobile communication capability and portable size. By way of example, it includes but is not limited to a smart phone, a laptop computer, a tablet computer, a smart bracelet, etc.

[0043] A trusted digital key connection channel can be established between the vehicle-mounted terminal 101 and the mobile terminal 102 through wireless communication methods such as Bluetooth for sending, receiving and transmitting information and signals. The wireless communication method is not limited to Bluetooth and is not specifically limited in this embodiment.

[0044] The following is an introduction to the data synchronization method provided in the embodiment of the present application.

[0045] Figure 2 200 is a flow chart of a data synchronization method provided by an embodiment of the present application. Figure 1 The data synchronization system shown.

[0046] like Figure 2 As shown, a data synchronization method may include the following steps S201 to S208.

[0047] S201, the vehicle terminal obtains location information of the mobile terminal when the mobile terminal executes the target service and is in communication connection with the vehicle terminal;

[0048] S202, when the vehicle terminal recognizes that the mobile terminal is located in the vehicle according to the location information, the vehicle terminal sends a synchronization request to the mobile terminal, where the synchronization request is used to request the vehicle terminal to synchronously execute the target service;

[0049] S203, the mobile terminal obtains synchronization information of the target service in response to the synchronization request;

[0050] S204, the mobile terminal sends the synchronization information to the vehicle terminal;

[0051] S205, the vehicle terminal obtains the service data of the target service according to the synchronization information;

[0052] S206: The vehicle-mounted terminal synchronously executes the target service according to the service data.

[0053] In the data synchronization method of the embodiment of the present application, the vehicle terminal can obtain the location information of the mobile terminal when the mobile terminal executes the target service and is connected to the vehicle terminal for communication, and send a synchronization request to the mobile terminal when the mobile terminal is identified as being in the vehicle based on the location information. The synchronization request is used to request the vehicle terminal to synchronously execute the target service; the mobile terminal responds to the synchronization request, obtains the synchronization information of the target service and sends the information to the vehicle terminal; the vehicle terminal then obtains the service data of the target service based on the synchronization information, and synchronously executes the target service. In this way, in the embodiment of the present application, when the mobile terminal executes the target service, the synchronization request can be triggered based on the location information of the mobile terminal, so as to realize the synchronous execution of the target service in the vehicle terminal, avoid the situation where the mobile terminal continues to operate in the vehicle environment, and thus improve the safety of driving.

[0054] In S201, the target service may be a service being executed by the mobile terminal, and may include, for example, an audio and video service and a navigation service. The audio and video service refers to a service for playing audio and / or video content provided by the mobile terminal. The navigation service refers to services such as positioning, route planning, and real-time navigation provided by the mobile terminal.

[0055] The above-mentioned vehicle-mounted terminal is communicatively connected with the vehicle-mounted terminal. Exemplarily, the vehicle-mounted terminal and the vehicle-mounted terminal can be communicatively connected based on the above-mentioned trusted digital key connection channel.

[0056] The above-mentioned acquisition of the location information of the mobile terminal may be, for example, that the vehicle-mounted terminal uses ultra-wideband (UWB) technology to accurately measure the distance and angle between the vehicle and the mobile terminal, thereby determining the location of the mobile terminal.

[0057] In S202, the synchronization request may be used to request the vehicle-mounted terminal to synchronously execute the target service.

[0058] When the vehicle-mounted terminal identifies that the mobile terminal is located in the vehicle based on the location information, the vehicle-mounted terminal sends a synchronization request to the mobile terminal. For example, when the vehicle-mounted terminal identifies that the mobile terminal is located in the vehicle based on the location information, the vehicle-mounted terminal sends a synchronization request to the mobile terminal based on the trusted digital key connection channel.

[0059] In S203, the synchronization information may be information involved in data synchronization operations in order to ensure data consistency and real-time performance between the vehicle-mounted terminal and the mobile terminal. For example, when the target service is an audio-visual service, the synchronization information may include data information of a third-party music player, such as account information, random / loop mode set by the player, playlist, current song ID, music name, singer name, play status, current song play time, current song total play time, etc. When the target service is a navigation service, the synchronization information may include data information of a third-party map, such as account information, departure point, destination, current location, etc.

[0060] The mobile terminal obtains the synchronization information of the target service in response to the synchronization request. For example, the mobile terminal directly obtains the synchronization information of the target service in response to the synchronization request. Alternatively, the synchronization request may include location information, and the mobile terminal obtains the synchronization information of the target service only when it recognizes that the mobile terminal is located in the vehicle according to the location information in response to the synchronization request.

[0061] In S204, the mobile terminal sends the synchronization information to the vehicle terminal. For example, the mobile terminal may send the synchronization information to the vehicle terminal based on the trusted digital key connection channel.

[0062] In S205, the business data may refer to data generated in a specific business scenario and used to support business operations. For example, when the target business includes an audio and video business, the business data includes audio and video data, and when the target business includes a navigation business, the business data includes navigation data.

[0063] The vehicle terminal obtains the service data of the target service according to the synchronization information. For example, the vehicle terminal may log in to the vehicle terminal according to the account information in the data information of the third-party music player, and obtain the real-time audio stream data of the breakpoint from the relevant online music server through the Internet of Vehicles based on other information in the data information of the third-party music player. Alternatively, the vehicle terminal may log in to the vehicle terminal according to the account information in the data information of the third-party map, and request the corresponding navigation data from the third-party online map server through the Internet of Vehicles based on other information in the data information of the third-party map.

[0064] In S206, the vehicle terminal synchronously executes the target service according to the service data. For example, when the capacity of the audio and video data is greater than the preset capacity threshold, the vehicle terminal sends a preparation signal to the mobile terminal, so that the mobile terminal responds to the preparation signal, stops executing the audio and video service, and generates stop information, the stop information includes the stop playback time; the vehicle terminal receives the stop information sent by the mobile terminal; the vehicle terminal starts playing the audio and video data from the stop playback time. Alternatively, the vehicle terminal synchronously executes the navigation service according to the navigation data and generates a stop signal; the vehicle terminal sends a stop signal to the mobile terminal, so that the mobile terminal responds to the stop signal and stops executing the navigation service.

[0065] In some embodiments, the synchronization request may include location information, and the above S203 may specifically include:

[0066] The mobile terminal responds to the synchronization request and acquires synchronization information of the target service when it is identified according to the location information that the mobile terminal is located in the vehicle.

[0067] In an embodiment of the present application, the mobile terminal responds to the synchronization request and obtains the synchronization information of the target service only when it is identified that the mobile terminal is located in the vehicle based on the location information. This ensures that the data synchronization of the mobile terminal is switched to the vehicle-mounted terminal only when the user enters the vehicle. That is, the vehicle-mounted terminal will not frequently attempt to synchronize data, thereby reducing interference with the user's mobile terminal.

[0068] In some embodiments, when the target service includes an audio and video service, the service data includes audio and video data, and S206 may specifically include:

[0069] When the capacity of the audio and video data is greater than a preset capacity threshold, the vehicle terminal sends a preparation signal to the mobile terminal;

[0070] The mobile terminal stops executing the audio and video service in response to the preparation signal and generates stop information, wherein the stop information includes a stop playback time;

[0071] The mobile terminal sends the stop information to the vehicle terminal;

[0072] The vehicle terminal starts playing the audio and video data from the time when the playback was stopped.

[0073] The situation that the capacity of the audio and video data is greater than the preset capacity threshold means that the condition that the online music is about to start playing can be met. Among them, the preset capacity threshold can be set according to the actual needs of the user and is not specifically limited here.

[0074] The vehicle terminal sends a preparation signal to the mobile terminal. For example, the vehicle terminal may send a preparation signal to the mobile terminal based on the trusted digital key connection channel. Alternatively, the vehicle terminal may initiate an audio switching request to the internal audio and video manager. After determining the legitimacy of the authorized device and the compliance of the audio source switching, the audio and video manager switches to the corresponding audio and prepares to start playing. The vehicle terminal then sends a preparation signal to the mobile terminal through the digital key connection channel to notify the vehicle terminal that the audio data is ready to start playing.

[0075] The above-mentioned stop information may include stop success feedback and stop playing time. Among them, stop success feedback may refer to the confirmation information given to the vehicle terminal by the music player or device of the mobile terminal confirming that the stop operation has been successfully executed after the vehicle terminal sends a preparation signal. Stop playing time refers to the time point when the music player or device in the vehicle terminal stops playing music.

[0076] The mobile terminal sends the stop information to the vehicle-mounted terminal. Exemplarily, the mobile terminal may send the stop information to the vehicle-mounted terminal based on the trusted digital key connection channel.

[0077] In an embodiment of the present application, when the above-mentioned target service includes an audio and video service and the service data includes audio and video data, the vehicle-mounted terminal sends a ready signal to the mobile terminal when the capacity of the audio and video data is greater than a preset capacity threshold. The mobile terminal responds to the ready signal, stops executing the audio and video service and generates a stop message, and then sends the stop message to the vehicle-mounted terminal. The stop message includes a stop playback time, so that the vehicle-mounted terminal can start playing the audio and video data from the stop playback time, thereby realizing the synchronous execution of the audio and video service on the vehicle-mounted terminal, and the mobile terminal can stop executing the audio and video service without affecting the power consumption of the mobile terminal.

[0078] In some embodiments, when the target service includes a navigation service, the service data includes navigation data, and S206 may specifically include:

[0079] The vehicle terminal synchronously executes the navigation service according to the navigation data and generates a stop signal;

[0080] The vehicle-mounted terminal sends a stop signal to the mobile terminal;

[0081] The mobile terminal stops executing the navigation service in response to the stop signal.

[0082] The above stop signal is used to instruct the mobile terminal to stop executing the navigation service.

[0083] The vehicle terminal synchronously executes navigation services according to the navigation data and generates a stop signal. Exemplarily, the vehicle terminal performs functions such as map loading and navigation prompts according to the navigation data and the current position and generates a stop signal.

[0084] The vehicle-mounted terminal sends a stop signal to the mobile terminal. Exemplarily, the vehicle-mounted terminal may send a stop signal to the mobile terminal based on the trusted digital key connection channel.

[0085] In an embodiment of the present application, when the above-mentioned target service includes a navigation service and the service data includes navigation data, the vehicle-mounted terminal synchronously executes the navigation service according to the navigation data, and generates a stop signal and sends it to the mobile terminal, so that the mobile terminal responds to the stop signal and stops executing the navigation service, thereby realizing the synchronous execution of the navigation service on the vehicle-mounted terminal, and the mobile terminal can stop executing the navigation service without affecting the power consumption of the mobile terminal.

[0086] As an implementation of the present application, in order to reliably achieve data synchronization, before the above S202, the above method may further include:

[0087] The mobile terminal sends a registration request to the vehicle terminal, the registration request includes a first key, and the registration request is used to request the vehicle terminal to register a digital key;

[0088] The vehicle-mounted terminal receives the registration request sent by the mobile terminal;

[0089] The vehicle terminal decrypts the first key in response to the registration request to obtain a first verification result, where the first verification result is used to indicate whether the first key is correct;

[0090] The vehicle terminal generates a second key when the first verification result indicates that the first key is correct;

[0091] The second key sent by the vehicle-mounted terminal to the mobile terminal;

[0092] The mobile terminal decrypts the second key to obtain a second verification result, where the second verification result is used to indicate whether the second key is correct;

[0093] When the second verification result indicates that the second key is correct, the mobile terminal establishes a communication connection channel with the vehicle-mounted terminal;

[0094] The vehicle-mounted terminal generates a digital key for the mobile terminal and sends it to the mobile terminal based on the communication connection channel.

[0095] The above S202 may specifically include: the vehicle-mounted terminal sends a synchronization request to the mobile terminal based on the communication connection channel.

[0096] The above S204 may specifically include: the mobile terminal sends the synchronization information to the vehicle-mounted terminal based on the communication connection channel.

[0097] The above registration request can be used to request the vehicle terminal to register the digital key.

[0098] The vehicle terminal decrypts the first key by using the same decryption algorithm as that in the mobile terminal. The mobile terminal decrypts the second key in the same way, which is not repeated here. The first key and the second key can be different keys.

[0099] In an embodiment of the present application, a communication connection channel between the mobile terminal and the vehicle-mounted terminal can be securely established through two-way key verification between the vehicle-mounted terminal and the mobile terminal, and the vehicle-mounted terminal sends the generated digital key based on this communication connection channel. Finally, the mobile terminal and the vehicle-mounted terminal can reliably synchronize data based on this digital key connection channel.

[0100] In order to facilitate the understanding of the data synchronization method in the embodiment of the present application, the actual application process of this data synchronization method is described as follows:

[0101] This application provides a method for triggering synchronization of audio or map data based on the location information of a mobile phone digital key. When a user enters a vehicle, the entire vehicle terminal synchronizes the relevant data to the vehicle terminal for seamless playback based on the location information of the mobile terminal provided by the digital key function, and the music playback information and map navigation information provided by the mobile terminal. Figure 3 As shown in the structural diagram, the vehicle side includes a digital key subsystem, a vehicle networking subsystem, an in-vehicle entertainment system, etc. These three systems are divided based on their functions. Specifically, they may be three different hardware ECUs or integrated into at least one hardware ECU.

[0102] 1. Automatic synchronization of multimedia audio data (similar to the online video synchronization method):

[0103] (1) The mobile terminal and the vehicle establish a trusted digital key connection channel.

[0104] (2) When the vehicle determines that the mobile terminal is located in the vehicle and the vehicle power mode meets certain conditions (for example, it is in the ON position), the vehicle sends a request instruction (equivalent to the above-mentioned synchronization request) containing location information (equivalent to the above-mentioned location information) to the mobile terminal based on its digital key channel with the mobile terminal.

[0105] (3) After the Internet of Vehicles application of the mobile terminal receives the corresponding request instruction, it determines that the location meets the conditions and starts to obtain the data information of the third-party music player (such as account information, random / loop mode set by the player, playlist, current song ID, music name, singer name, play status, current song play time, current song total play time, etc.) (equivalent to the above-mentioned synchronization information) and transmits it to the vehicle end (when the mobile terminal app is not logged in, it mainly obtains the information of the currently playing music).

[0106] (4) The vehicle detects that the Internet of Vehicles has good data communication capabilities, and the corresponding third-party music player is logged in to the in-vehicle entertainment system. The vehicle obtains the real-time audio stream data (equivalent to the business data of the above-mentioned target business) of the breakpoint from the relevant online music server through the Internet of Vehicles. (If there are restrictions on the login device ID for the third-party audio player, then the method of associating the relevant hardware ID of the vehicle ECU with the hardware ID of the mobile terminal can be used)

[0107] (5) When the in-vehicle entertainment system has obtained a certain amount of audio data (which can meet the conditions for online music to start playing) through the Internet of Vehicles system, it initiates an audio switching request to its internal audio and video manager. After determining the legitimacy of the authorized device and the compliance of the audio source switching, the audio and video manager switches to the corresponding audio and prepares to start playing.

[0108] (6) The in-vehicle entertainment system notifies the mobile terminal through the digital key system (equivalent to the above-mentioned preparation signal) that the audio data on the in-vehicle side is ready to start playing. After receiving the notification, the mobile terminal stops playing the audio on the mobile terminal and feeds back a message of successful stop (equivalent to the above-mentioned stop information) to the vehicle side.

[0109] (7) After the vehicle-side in-vehicle entertainment system receives the notification from the mobile terminal (including the time point of stopping playback, i.e., the above-mentioned stop playback time), it immediately starts to continue playing the corresponding online audio data on the vehicle side.

[0110] 2. Automatic synchronization of navigation data:

[0111] (1) The digital key system of the mobile terminal and the vehicle establishes a trusted digital key connection channel.

[0112] (2) When the digital key system of the vehicle determines that the mobile terminal is located in the vehicle and the vehicle power mode meets certain conditions (for example, it is in the ON position), the vehicle sends a request instruction containing location information to the mobile terminal based on its digital key security channel with the mobile terminal.

[0113] (3) After receiving the corresponding request, the Internet of Vehicles application of the mobile terminal determines that the location meets the conditions, starts to obtain the data information of the third-party map being navigated (such as account information, departure point, destination, current location, etc.) (equivalent to the above-mentioned synchronization information), and transmits it to the vehicle end (the corresponding data is forwarded to the in-vehicle entertainment system via the digital key system)

[0114] (4) The in-vehicle entertainment system detects that the Internet of Vehicles has good data communication capabilities, and the corresponding third-party map application is logged in to the in-vehicle entertainment system on the vehicle side.

[0115] (5) The vehicle uses the relevant data provided by the mobile terminal to request the corresponding navigation data (equivalent to the business data of the above-mentioned target business) from the third-party online map server through the Internet of Vehicles, and performs functions such as map loading and navigation prompts in combination with the current location.

[0116] (6) The in-vehicle entertainment system notifies the mobile terminal through the digital key system (equivalent to the above-mentioned stop signal), and the mobile terminal's Internet of Vehicles application stops the navigation route planning of the third-party map application.

[0117] It should be noted that the data synchronization method can be set to automatic synchronization or authorized synchronization on the in-car entertainment system. For authorized synchronization, the user needs to confirm on the in-car entertainment system, and then the corresponding audio, video and map playback will be completely switched to the in-car entertainment system. The specific confirmation method can be manual confirmation through the button of the in-car entertainment system or voice command confirmation. In particular, for some mobile phones that support simultaneous navigation and music playback, the car side obtains online data of the two types of services, and the in-car entertainment system integrates the two types of data on the car side.

[0118] In the embodiment of the present application, the music or navigation functions can be switched to the vehicle side seamlessly and smoothly based on the automatic triggering of the mobile terminal location and other conditions, and based on a reliable and secure channel. In addition, only a small amount of breakpoint data is synchronized, and after the data synchronization is successful, the mobile phone side can exit the work, and the music or navigation and other related functions do not affect the power consumption of the mobile terminal.

[0119] Based on the data synchronization method provided in the above embodiment, the present application also provides a specific implementation of the data synchronization device. Please refer to the following embodiment.

[0120] like Figure 4As shown, a data synchronization device 400 provided in an embodiment of the present application is applied to a vehicle-mounted terminal. The device 400 may include the following modules: a first acquisition module 401, a first sending module 402, a first receiving module 403, a second acquisition module 404 and a synchronization execution module 405.

[0121] The first acquisition module 401 is used to acquire the location information of the mobile terminal when the mobile terminal executes the target service and is in communication connection with the vehicle terminal;

[0122] The first sending module 402 is used to send a synchronization request to the mobile terminal when it is identified according to the location information that the mobile terminal is located in the vehicle, wherein the synchronization request is used to request the vehicle-mounted terminal to synchronously execute the target service, so that the mobile terminal responds to the synchronization request and obtains synchronization information of the target service;

[0123] The first receiving module 403 is used to receive synchronization information sent by the mobile terminal;
