[0018] File transfer method

[0019] The embodiment of the present application provides a file transfer method. Through this method, cross-terminal operation of applications between the mobile terminal and the vehicle terminal can be achieved, improving the user experience.

[0020] Figure 1 It is a flowchart of the file transfer method according to an embodiment of the present application. The file transfer method of this embodiment is applied to a mobile terminal. Among them, the mobile device corresponding to the mobile terminal can be a device such as a mobile phone or a tablet.

[0021] As Figure 1 shown, the file transfer method in this embodiment includes the following steps:

[0022] Step 101: Obtain the first window information of the mirror window of the target application on the mobile terminal on the vehicle terminal display screen.

[0023] In an implementable manner, stable communication links can be established between the mobile terminal and the vehicle terminal by using wireless communication technologies such as Wi-Fi and Bluetooth. The mirror data of the mobile terminal can be sent to the vehicle terminal through the near-field communication protocol between the mobile terminal and the vehicle terminal, such as the carlink protocol, so that the vehicle terminal can display the mirror window on the display screen according to the mirror data. Among them, the mirror data includes the mirror data of all contents of the mobile desktop, such as the mirror data of application programs in the desktop and the mirror data of application files included in the application program. As an example, all mirror data corresponding to the desktop of the mobile terminal can be sent to the vehicle terminal, and the same interface as the desktop of the mobile terminal can be displayed on the display screen of the vehicle terminal, such as displaying the photo album application, music application, etc., and all photos in the photo album application, all music in the music application, etc. data.

[0024] In an implementable embodiment, first window information of a mirror window of a target application on a mobile terminal on a vehicle-mounted display screen can be obtained. Among them, after all the contents of the desktop of the mobile terminal are displayed on the vehicle-mounted display screen, the application currently selected and opened on the vehicle-mounted display screen can be determined as the target application, the mirror window of the target application on the vehicle-mounted display screen can be determined, and the first window information of the mirror window can be determined. The first window information may include the size information of the window after the target application is opened on the vehicle-mounted display screen. By using the near-field communication protocol and only transmitting the mirror data of the mobile terminal to the vehicle end, the transmission delay can be reduced, the data transmission rate and stability can be improved, and at the same time, the vehicle end can display all the contents of the desktop of the mobile terminal, meeting the requirement of the vehicle end to view the application files of the mobile terminal and enhancing the user experience.

[0025] Step 102: Determine the position conversion relationship between the mirror window and the application window of the target application on the mobile terminal according to the first window information.

[0026] In an implementable embodiment, second window information corresponding to the application window of the target application on the mobile terminal can be obtained. The second window information may be the size information of the window after the target application is opened on the mobile terminal display screen.

[0027] In an implementable embodiment, the ratio of the size information of the first window in the first direction to the size information of the second window information in the first direction can be obtained, and the first scaling ratio of the target application in the first direction on the vehicle-mounted screen can be determined according to the ratio; the ratio of the size information of the first window in the second direction to the size information of the second window information in the second direction can be obtained, and the first scaling ratio of the target application in the second direction on the vehicle-mounted screen can be determined according to the ratio. The position conversion relationship can be determined according to the first ratio and the second ratio. Among them, the first direction may be the x-axis direction, and the second direction may be the y-axis direction. By obtaining the first window information, the scaling ratio of the target application between the vehicle-mounted display screen and the mobile terminal display screen can be accurately determined, so as to accurately determine the position conversion relationship between the vehicle-mounted display screen and the mobile terminal display screen, which is beneficial to realizing the accuracy of gesture operations and file dragging operations on the vehicle end and enhancing the user experience.

[0028] Step 103: Obtain the first position information.

[0029] In an implementable embodiment, the position of the selected target position on the vehicle-mounted display screen in the mirror window can be obtained, and the coordinates corresponding to the position can be determined as the first position information. By accurately obtaining the coordinate position of the target file on the vehicle-mounted display screen, the operation position of the user on the vehicle-mounted display screen can be accurately located.

[0030] Step 104: Convert the first location information into second location information according to the location conversion relationship.

[0031] In an implementable manner, second window information corresponding to an application window of a target application on a mobile terminal can be obtained. The second window information may be size information of the window after the target application is opened on the display screen of the mobile terminal.

[0032] In an implementable manner, a ratio of the size information of the first window in a first direction to the size information of the second window information in the first direction can be obtained, and a first scaling ratio of the target application in the first direction on the vehicle terminal screen can be determined according to the ratio; a ratio of the size information of the first window in a second direction to the size information of the second window information in the second direction can be obtained, and a first scaling ratio of the target application in the second direction on the vehicle terminal screen can be determined according to the ratio. The location conversion relationship can be determined according to the first ratio and the second ratio. Wherein, the first direction may be the x-axis direction, and the second direction may be the y-axis direction.

[0033] In an implementable manner, a value of the first location information in a first direction and a first scaling ratio of the location conversion relationship in the first direction can be obtained, and a value of the second location information in the first direction can be determined according to the value in the first direction and the first ratio. A value of the first location information in a second direction and a second scaling ratio of the location conversion relationship in the second direction can be obtained, and a value of the second location information in the second direction can be determined according to the value in the second direction and the second ratio. As an example, a value of the second location information in the first direction can be determined according to a ratio between the value in the first direction and the first ratio; a value of the second location information in the second direction can be determined according to a ratio between the value in the second direction and the second ratio.

[0034] In an implementable manner, the second location information can be determined according to the value in the first direction and the value in the second direction. Wherein, the first direction may be the x-axis direction, and the second direction may be the y-axis direction.

[0035] Through the first window information and the second window information, the location conversion relationship between the mobile terminal display screen and the vehicle terminal display screen can be accurately determined, so that the position of the target file selected in the vehicle terminal can be accurately corresponded to the position of the target file on the mobile terminal, and it can be applicable to different mobile terminals and vehicle terminals, with strong compatibility and versatility.

[0036] Step 105: Send the file data corresponding to the target file to the vehicle terminal according to the second location information.

[0037] In an implementable embodiment, after obtaining the second location information, the file information of the target file may be determined according to the second location information, and the file data corresponding to the target file may be obtained according to the file information. The file data is sent to the vehicle terminal through the near field communication protocol, and the vehicle terminal stores the file data or performs the next operation on the target file based on the file data. As an example, if the target file is an album application, the vehicle terminal sends the first location information of the target photo selected in the album application in the mirror window of the vehicle terminal display screen to the mobile terminal. The mobile terminal determines the second location information of the target photo in the mobile terminal according to the first location information and the location conversion relationship, determines the file information of the target photo according to the second location information, such as file encoding or file name, determines the storage location of the target photo according to the file information, and obtains the target data of the target photo from the storage location, and sends the target data to the vehicle terminal. After receiving the target data, the vehicle terminal stores the target data. By determining the target data corresponding to the target file according to the second location information, data transmission and content sharing between the mobile terminal and the vehicle terminal can be realized, the requirement of the user to view the application files on the mobile phone on the vehicle terminal can be met, and the user experience is improved.

[0038] Through the near field communication protocol, this application can make the content on the display screen of the vehicle terminal completely display the content on the display screen of the mobile terminal, realizing data sharing between the vehicle terminal and the mobile terminal; by determining the location conversion relationship between different positions on the display screen of the vehicle terminal and the display screen of the mobile terminal, when dragging or selecting a target file on the vehicle terminal display screen, the file data corresponding to the target file in the mobile terminal can be accurately located, so as to accurately and efficiently realize the requirement of viewing or configuring files on the vehicle terminal on the vehicle terminal, improving the user experience.

[0039] File transfer method

[0040] The embodiment of this application provides a file mutual transmission method. The file mutual transmission method of this embodiment is applied to the vehicle terminal, and the vehicle terminal may be the vehicle-mounted system in an intelligent connected vehicle.

[0041] Step 201: Send the first window information of the mirror window of the target application on the vehicle terminal display screen to the mobile terminal.

[0042] In an implementable embodiment, wireless communication technologies such as Wi-Fi and Bluetooth can be used to establish a stable communication link between the mobile terminal and the vehicle terminal. The mirror data of the mobile terminal can be sent to the vehicle terminal through a near-field communication protocol between the mobile terminal and the vehicle terminal, such as the carlink protocol. The vehicle terminal can display the mirror data of the mobile terminal, and the mirror data includes the desktop content of the mobile terminal, such as the mirror data of the application programs on the desktop and the mirror data of the application files within the application program. That is, the information of the desktop of the mobile terminal can be displayed on the vehicle terminal display screen. The vehicle terminal can also perform operations such as dragging on the application programs or application files included in the displayed desktop, such as the photos in the album. After the vehicle terminal selects a target application in the application program and opens it, the vehicle terminal can display the mirror window of the target application.

[0043] In an implementable embodiment, the first window information of the mirror window of the target application on the vehicle terminal can be obtained. Among them, the first window information can include the size information of the window after the target application is opened on the vehicle terminal display screen. Through the near-field communication protocol, the vehicle terminal can display the mirror data of the mobile terminal, which meets the requirement of the vehicle terminal to view the application files of the mobile terminal and improves the user experience.

[0044] Step 202: Obtain the first position information of the selected target file in the mirror window and send the first position information to the mobile terminal.

[0045] In an implementable embodiment, when the vehicle terminal operates on the target application and selects a target file in the target application, the first position information corresponding to the target file in the mirror window of the vehicle terminal can be obtained. The first position information can be the position information of the target file in the mirror window after it is opened on the mobile terminal display screen. The first position includes a value in the first direction and a value in the second direction. The first position information can be sent to the mobile terminal. Among them, the first direction can be the x-axis direction, and the second direction can be the y-axis direction.

[0046] By sending the first window information and the first position information to the mobile terminal, the scaling ratio of the target application between the vehicle terminal display screen and the mobile terminal display screen can be accurately determined, so as to accurately determine the position conversion relationship between the vehicle terminal display screen and the mobile terminal display screen, which is beneficial to the vehicle terminal accurately obtaining the file data corresponding to the target file and improving the user experience.

[0047] Step 203: Obtain the target data corresponding to the target file.

[0048] In one implementable manner, the mobile terminal converts the first location information into the second location information of the target file in the application window on the mobile terminal according to the location conversion relationship, and determines the target data based on the second location information. After obtaining the target data, the vehicle terminal can perform configuration operations based on the target data. As an example, if the obtained target file is a photo in the album, the vehicle terminal can set the wallpaper on the display screen of the vehicle terminal based on the photo after obtaining the target data. By determining the target data corresponding to the target file according to the second location information, data transmission and content sharing between the mobile terminal and the vehicle terminal can be realized, the requirement of the user to view the application files on the mobile phone on the vehicle terminal can be met, and the requirement of configuring the vehicle terminal based on the obtained application files can be met, improving the user experience.

The vehicle terminal obtains the mirror data of the mobile terminal through the private communication protocol and displays the desktop content corresponding to the mirror data on the display screen of the vehicle terminal.

[0051] In the vehicle terminal, operations of interface interaction on the display screen can be monitored, such as click, drag, etc. If the target application is selected, the first window information of the mirror window corresponding to the target application can be obtained and sent to the mobile terminal. Through the first window information and the second window information of the interface window of the target application on the mobile terminal of the mobile terminal, the location conversion relationship between different positions on the vehicle terminal display screen and the mobile terminal display screen is determined.

[0052] In the vehicle terminal, when the target file in the target application is clicked or dragged, the first coordinate information of the target file in the mirror window is obtained, and the first coordinate information is transmitted to the mobile terminal through the private communication protocol. And the file information corresponding to the target file in the interface window obtained by the mobile terminal for the first coordinate information and the location conversion relationship, such as file encoding or file name, can be used to determine the storage location of the file according to the file information of the target file, and the file data corresponding to the target file is obtained from the storage location and transmitted to the vehicle terminal through the private communication protocol. The vehicle terminal can perform corresponding settings based on the file data of the target file. For example, if the target file is a target photo, the desktop wallpaper of the vehicle terminal display screen or others can be set based on the photo.
