For example, the interface data, picture data and the like involved in the present application are obtained under sufficient authorization.

[0062] The embodiment of the present application provides a vehicle-mounted display system, referring to Figure 1 The system comprises a controller 10, a central control machine 20, a rear-row display screen 30 and a terminal 40, wherein the rear-row display screen 30 is a display screen installed in the rear row.

[0063] The controller 10 is provided with a first input interface 101, a second input interface 102 and a first output interface 103.

[0064] The first input interface 101 is electrically connected with the central control machine 20, the second input interface 102 is electrically connected with the terminal 40, and the first output interface 103 is electrically connected with the rear-row display screen 30.

[0065] The central control machine 20 is used for displaying a first interface through a central control display screen.

[0066] The terminal 40 is used for displaying a control interface, wherein the control interface comprises a first display source option corresponding to the central control machine 20; and the terminal 40 is used for sending a first control instruction to the controller 10 in response to a selection operation on the first display source option.

[0067] The controller 10 is used for acquiring interface data of the first interface based on the first control instruction, and controlling the rear-row display screen 30 to display the first interface based on the interface data of the first interface.

[0068] In the embodiment of the present application, the controller 10 is provided with the first input interface 101 and the second input interface 102. The first input interface 101 is electrically connected with the central control machine 20, and the second input interface 102 is electrically connected with the terminal 40. The types of the first input interface 101 and the second input interface 102 can be set and changed according to needs, and no specific limitation is made to this. For example, the first input interface 101 is an LVDS (Low Voltage Differential Signaling) interface, and the second input interface 102 is an HDMI (High Definition Multimedia Interface) interface.

[0069] The controller 10 is also provided with the first output interface 103, and the first output interface 103 is electrically connected with the rear-row display screen 30. The type of the first output interface 103 can also be set and changed according to needs, and no specific limitation is made to this. For example, the first output interface 103 is an HDMI interface.

[0070] The terminal 40 can be a terminal used by a driver, a terminal used by a front passenger, or a terminal used by a rear passenger, and is not specifically limited. When the terminal 40 is a terminal used by a driver, the driver can control the content displayed by the rear display screen 30 through the terminal 40. When the terminal 40 is a terminal used by a front passenger, the front passenger can control the content displayed by the rear display screen 30 through the terminal 40. When the terminal 40 is a terminal used by a rear passenger, the rear passenger can control the content displayed by the rear display screen 30 through the terminal 40.

[0071] In the embodiment of the present application, the terminal 40 is installed with a target application. In response to detecting a login operation of logging into the target application, the terminal 40 displays a control interface, and the control interface includes a first display source option corresponding to the center console 20. In response to a selection operation on the first display source option, a first control instruction is sent to the controller 10.

[0072] The controller 10 includes a conversion module and a control module. The conversion module is mainly used to process the input data signal, and format converts the input data signal into a display format corresponding to the rear display screen 30 and outputs it. The control module is mainly used to interact with other devices, such as the terminal 40 and the center console 20, receive instructions or send requests, see Figure 2 .

[0073] Correspondingly, the controller 10 receives the first control instruction through the control module, sends an interface acquisition request to the center console 20, the center console 20 receives the interface acquisition request, acquires the interface data of the first interface, and sends the interface data of the first interface to the control module, so that the controller 10 acquires the interface data of the first interface. After the controller 10 acquires the interface data of the first interface through the control module, the control module sends the interface data of the first interface to the conversion module, the conversion module converts and processes the interface data of the first interface, and then outputs the converted and processed interface data of the first interface to the rear display screen 30. The rear display screen 30 renders the interface data of the first interface, so as to display the first interface.

[0074] If the first interface is an interface with audio, continuing to refer to Figure 1 The system further includes a sound equipment 50, and the controller 10 plays the corresponding audio through the sound equipment 50, so as to meet the needs of the rear passengers.

[0075] Correspondingly, the controller 10 is also provided with a second output interface 104, and the second output interface 104 is electrically connected with the sound equipment 50.

[0076] The controller 10 is also used to control the sound equipment 50 to play the audio corresponding to the first interface based on the interface data of the first interface.

[0077] The audio device is an in-vehicle audio device. In the embodiments of the present application, in addition to playing audio through the in-vehicle audio device, the audio device can also be separately arranged or audio can be played through a Bluetooth audio device, a headset or other means, and no specific limitation is made in this regard.

[0078] In the embodiments of the present application, the first interface can display a plurality of vehicle-mounted function options, one vehicle-mounted function option corresponding to one vehicle-mounted function, and the rear passengers can start the corresponding vehicle-mounted function by triggering the vehicle-mounted function option. Correspondingly, the central control machine 20 is further configured to send a starting request to the controller 10 in response to detecting the triggering operation of any vehicle-mounted function option.

[0079] The controller 10 is further configured to start the vehicle-mounted function corresponding to the vehicle-mounted function option based on the starting request.

[0080] The vehicle-mounted function can be an air conditioning function, a navigation function or other functions, and no specific limitation is made in this regard. Of course, for any vehicle-mounted function, the rear passengers can also adjust the vehicle-mounted function through the rear display screen 30 after the vehicle-mounted function is started. For example, when the vehicle-mounted function is an air conditioning function, the rear passengers can adjust the temperature and air volume of the air conditioner through the rear display screen 30.

[0081] In the embodiments of the present application, when the rear passengers want to watch the first interface displayed on the central control display screen or operate the first interface, the interaction among the terminal 40, the controller 10 and the central control machine 20 can be used to achieve this, thereby meeting the needs of the rear passengers.

[0082] It should be noted that before the rear display screen 30 displays the first interface, the user can first turn on the screen of the rear display screen 30 or set the picture function of the rear display screen 30 through the terminal 40.

[0083] For example, the rear passengers turn on the screen of the rear display screen 30 through the terminal 40. Correspondingly, the terminal 40 displays a control interface, the control interface including a function setting option corresponding to the rear display screen 30, the terminal 40 displays a function setting interface in response to the triggering operation of the function setting option, the function setting interface including a screen on-off option, the terminal 40 sends an on instruction to the controller 10 in response to the triggering operation of the screen on-off option, and the controller 10 receives the on instruction and controls the rear display screen 30 to turn on.

[0084] Similarly, the rear passengers can also turn off the screen of the rear display screen 30 through the terminal 40. The terminal 40 sends a close instruction to the controller 10 in response to the re-triggering operation of the screen on-off option, and the controller 10 receives the close instruction and controls the rear display screen 30 to turn off.

[0085] For example, the rear passenger sets the picture function of the rear display screen 30 through the terminal 40. Correspondingly, the function setting interface further includes a plurality of picture setting options, such as a resolution setting option, a display parameter setting option, a brightness setting option, a contrast setting option, and other setting options. In response to a triggering operation on any picture setting option, the terminal 40 acquires a setting parameter corresponding to the picture setting option, and then sends a setting instruction to the controller 10, where the setting instruction carries the setting parameter. The controller 10 receives the setting instruction, and controls the picture function of the rear display screen 30 based on the setting parameter.

[0086] In the embodiments of the present application, after the controller 10 controls the rear display screen 30 to display the first interface, turn on or off the screen, set the picture function, or perform other operations, the controller 10 can feed back to the terminal 40, so as to facilitate the rear passenger to understand the state of the rear display screen 30. Correspondingly, the controller 10 is further configured to acquire the running state of the rear display screen 30, and send the running state to the terminal 40;

[0087] The terminal 40 is further configured to display the running state.

[0088] For example, after the controller 10 successfully turns on the screen of the rear display screen 30, the controller 10 can send a notification message to the terminal 40, and the terminal 40 displays the notification message, such as “the screen has been successfully turned on”, so as to facilitate the rear passenger to perform subsequent operations.

[0089] It should be noted that the target application can also be installed on the central control machine 20, so that the front passenger or the driver can also control the rear display screen 30 to display the first interface. The process is as follows: the central control machine 20 displays the first interface through the central control display screen, the target application is installed on the central control machine 20, in response to detecting a login operation of logging into the target application through the central control display screen, a control interface is displayed through the central control display screen, the control interface includes a first display source option corresponding to the central control machine 20; in response to detecting a selection operation on the first display source option through the central control display screen, a second control instruction is sent to the controller 10, and the second control instruction carries the interface data of the first interface. The controller 10 receives the second control instruction, controls the rear display screen 30 to render the interface data of the first interface, so as to control the rear display screen 30 to display the first interface.

[0090] The process of the controller 10 controlling the rear display screen 30 to display the first interface based on the second control instruction is the same as the process of the controller 10 controlling the rear display screen 30 to display the first interface based on the first control instruction, which will not be described here.

[0091] The above is described by taking the example that the central control machine 20 controls the rear-row display screen 30 to display the first interface in response to the operation of the front-row passenger. In the embodiment of the present application, the central control machine 20 can also automatically control the rear-row display screen 30 to display the first interface. The process is as follows: the system further includes: a third camera, which is arranged in the vehicle and is used to capture a face image of the rear-row passenger and send the face image to the central control machine 20;

[0092] The central control machine 20 is further configured to determine a region where a line of sight of the rear-row passenger is located based on the face image, acquire interface data of the first interface if the region where the line of sight is located is the region where the central control display screen is located, and send the interface data of the first interface to the controller 10.

[0093] The controller 10 is further configured to control the rear-row display screen 30 to display the first interface based on the interface data of the first interface.

[0094] In this implementation manner, the third camera can capture the face image of the rear-row passenger in real time or periodically, and then send the face image to the central control machine 20. The central control machine 20 identifies the face image to determine the region where the line of sight of the rear-row passenger is located. If the region where the line of sight is located is the region where the central control display screen is located, it indicates that the rear-row passenger wants to watch the first interface displayed by the central control display screen. In this case, the central control machine 20 sends the interface data of the first interface to the controller 10, so that the controller 10 controls the rear-row display screen 30 to display the first interface.

[0095] In a possible implementation manner, after determining that the region where the line of sight of the rear-row passenger is located is the region where the central control display screen is located, the central control machine 20 determines a time length during which the line of sight of the rear-row passenger falls in the region where the central control display screen is located. If the time length is greater than a first preset time length, the central control machine 20 sends the interface data of the first interface to the controller 10.

[0096] In another possible implementation manner, after determining that the region where the line of sight of the rear-row passenger is located is the region where the central control display screen is located, the central control machine 20 determines a number of times that the line of sight of the rear-row passenger falls in the region where the central control display screen is located within a second preset time length. If the number of times is greater than a preset number of times, the central control machine 20 sends the interface data of the first interface to the controller 10.

[0097] In another possible implementation manner, after determining that the region where the line of sight of the rear-row passenger is located is the region where the central control display screen is located, the central control machine 20 determines a time length during which the line of sight of the rear-row passenger falls in the region where the central control display screen is located and a number of times that the line of sight of the rear-row passenger falls in the region where the central control display screen is located within a second preset time length. If the time length is greater than a first preset time length or the number of times is greater than a preset number of times, the central control machine 20 sends the interface data of the first interface to the controller 10.

[0098] In the embodiment of the present application, the central control car machine 20 can control the rear-row display screen 30 to automatically display the first interface according to whether the area where the line of sight of the rear-row passenger is located is the area where the central control display screen is located, without manual operation of the rear-row passenger, thereby improving the experience of the rear-row passenger.

[0099] It should be noted that, if the rear-row display screen 30 does not display other interfaces or pictures before displaying the first interface, the rear-row display screen 30 can directly display the first interface. If the rear-row display screen 30 displays other interfaces or pictures before displaying the first interface, the rear-row display screen 30 switches from the other interfaces or pictures to the first interface. For example, the rear-row display screen 30 currently displays a third interface, and the controller 10 controls the rear-row display screen 30 to switch from the third interface to the first interface after obtaining the interface data of the first interface.

[0100] Among them, the controller 10 can control the rear-row display screen 30 to directly switch, or display a prompt message through the rear-row display screen 30 before switching to prompt the rear-row passenger, thereby improving the experience of the rear-row passenger. For example, the rear-row display screen 30 displays a message "Switching to the interface displayed by the central control display screen soon". Or display a message box through the rear-row display screen 30 before switching to prompt the rear-row passenger to confirm whether to switch, thereby avoiding false triggering. For example, the rear-row display screen 30 displays a message box "Do you want to switch to the interface displayed by the central control display screen", and displays "Yes" and "No" options, and switches from the third interface to the first interface when it is detected that the "Yes" option is triggered. And when it is detected that the "No" option is triggered, the first interface is still displayed.

[0101] In the embodiment of the present application, the user can also control the rear-row display screen 30 to display the picture in front of the vehicle through the terminal 40, thereby facilitating the rear-row passenger to understand the situation in front of the vehicle, and also can guide the driver. At the same time, for the rear-row passenger who is prone to car sickness, the rapidly changing picture in front can be seen, and the speed can be felt, which has a certain relieving effect on car sickness, which is also the reason why people prone to car sickness do not get car sickness when they drive themselves.

[0102] Correspondingly, continuing to refer to Figure 1 The system further includes: a first camera 60, and the controller 10 is further provided with a third input interface 105, and the third input interface 105 is electrically connected with the first camera 60;

[0103] The control interface further includes: a second display source option corresponding to the first camera 60;

[0104] The first camera 60 is used for shooting a first picture in front of the vehicle;

[0105] The terminal 40 is further used for sending a second control instruction to the controller 10 in response to a selection operation on the second display source option;

[0106] The controller 10 is further configured to acquire picture data of the first picture based on the second control instruction, and control the rear display screen 30 to display the first picture based on the picture data of the first picture.

[0107] In this implementation, the first camera 60 is used to capture the first picture in real time or periodically. When the rear passenger wants to view the situation in front of the vehicle, the second display source option can be selected. Correspondingly, the terminal 40 detects the selection operation on the second display source option and sends a second control instruction to the controller 10. The controller 10 receives the second control instruction and sends a first picture acquisition request to the first camera 60. The first camera 60 receives the first picture acquisition request and sends picture data of the first picture to the controller 10. The controller 10 receives the picture data of the first picture and controls the rear display screen 30 to render the picture data of the first picture, thereby controlling the rear display screen 30 to display the first picture.

[0108] It should be noted that if the rear display screen 30 does not display other interfaces or pictures before displaying the first picture, the rear display screen 30 can directly display the first picture. If the rear display screen 30 displays other interfaces or pictures before displaying the first picture, the rear display screen 30 switches from the other interfaces or pictures to the first picture.

[0109] The controller 10 can control the rear display screen 30 to directly switch or display a prompt message on the rear display screen 30 to prompt the rear passenger before switching, thereby improving the experience of the rear passenger. For example, the rear display screen 30 displays a message “Switching to the picture in front of the vehicle soon”. Or, a message box is displayed on the rear display screen 30 before switching to prompt the rear passenger to confirm whether to switch, thereby avoiding accidental triggering. For example, the rear display screen 30 displays a message box “Do you want to switch to the picture in front of the vehicle” and displays “Yes” and “No” options. When the “Yes” option is triggered, the first picture is switched to. When the “No” option is triggered, the current interface or picture is still displayed.

[0110] The positions and the number of the first cameras 60 can be set and changed as needed, and no specific limitation is made. In addition, the type of the third input interface 105 can be set and changed as needed, for example, the third input interface 105 is an LVDS interface.

[0111] In the embodiments of the present application, the user can also cast the content displayed on the screen of the terminal 40 to the rear display screen 30, so that the rear passenger can operate the terminal 40 through the rear display screen 30. Correspondingly, the control interface further includes a third display source option corresponding to the terminal 40.

[0112] The terminal 40 is further configured to send a third control instruction to the controller 10 in response to the selection operation on the third display source option, the third control instruction carrying interface data of a second interface currently displayed by the terminal 40.

[0113] The controller 10 is further configured to control the rear display screen 30 to display the second interface based on the interface data of the second interface.
