[0054] Figure 6 FIG. 1 is a flow chart of a first embodiment of a method for controlling a car entertainment device according to the present invention.

[0055] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0056] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0057] The embodiment of the present invention provides a car entertainment device control system, referring to Figure 1 , Figure 1 This is a structural diagram of a first embodiment of a car entertainment device control system according to the present invention.

[0058] In this embodiment, the car central control screen control system includes: a host 10, a passenger controller 20, and a passenger display screen 30;

[0059] It is understandable that the host 10 can be a controller installed inside the car, which can be used to receive signals sent by the central control controller and the co-pilot controller 20, and control the entertainment equipment inside the car according to the signals, such as playing music, opening the roof, starting navigation, automatic driving, etc.

[0060] It should be understood that the automobile entertainment equipment control system also includes a central control controller 40 and a central control display screen; among them, the passenger controller 20 can receive relevant signals from the passenger display screen 30, and perform simple operations according to the relevant signals of the passenger display screen 30 or send corresponding signals to the host 10. Correspondingly, the central control controller can receive relevant signals from the passenger display screen 30, and perform simple operations according to the relevant signals of the passenger display screen 30 or send corresponding signals to the host 10.

[0061] It should be noted that this embodiment is carried out when there are two or three screens in the car. In the case of further expansion, the co-pilot controller 20 and the co-pilot display screen 30 can be any one of the other associated display screens / controllers except the central control controller 40 / central control display screen.

[0062] The passenger controller 20 is used to determine whether the passenger control mode is currently activated according to the pressing signal, and send a trigger signal to the host 10 when the passenger control mode is activated;

[0063] It can be understood that the press signal can be understood as the signal collected when the user operates on the co-pilot screen. It can be further understood that the press signal can include the position of the signal when it is pressed on the screen, and can also include the pressure value when the screen is pressed.

[0064] It is understandable that the trigger signal is a pre-set signal sent to the host 10 when the co-pilot control mode is started, so that the host 10 knows that the co-pilot control mode has been started when receiving the signal and performs relevant operations in the co-pilot control mode.

[0065] In a specific implementation, the user clicks hard on the central control icon on the co-pilot display screen 30. At this time, the position where the user clicks the screen is obtained, and it is determined that the position where the user clicks the screen is consistent with the position of the central control icon on the co-pilot display screen 30, and the pressure value when clicking the screen is greater than the false touch threshold, then the co-pilot operation mode is started and a trigger signal is sent to the host 10.

[0066] It is worth noting that setting the false touch threshold here can prevent users from accidentally making false operations when performing screen operations to a limited extent.

[0067] The host 10 is used to receive the trigger signal and transmit the central control display screen to the passenger display screen 30 after receiving the trigger signal;

[0068] It is understandable that the trigger signal can be a protocol signal between the passenger controller 20 and the host 10. When the protocol signal is received, the central control display screen is transmitted to the passenger display screen 30.

[0069] It should be understood that the central control display screen can be a screen displayed on the central control display screen that can be used to operate the car entertainment equipment.

[0070] The passenger controller 20 is used to receive and display the central control display screen, obtain touch signals on the passenger display screen 30, and control the car entertainment equipment according to the touch signals.

[0071] It is understandable that the host 10 sends the central control display screen to the passenger display screen 30 for display, and the passenger display screen 30 displays the screen originally on the central control display screen. The user can select the entertainment device he wants to control based on the central control display screen displayed on the passenger display screen 30 at this time.

[0072] In this embodiment, when the buttonless central control screen is damaged and cannot be operated, the passenger control mode is entered through the passenger touch screen to realize control of various entertainment functions of the car without affecting the use of the car's central control, improving the user experience and vehicle driving safety factor, and solving the problem that the touch screen is prone to accidental loss of control during the use of the central control screen, thereby making the entire car entertainment function unusable and seriously affecting the car driving experience.

[0073] The embodiment of the present invention provides a car entertainment device control system, referring to Figure 2 , Figure 2 This is a structural diagram of a second embodiment of a car entertainment device control system according to the present invention.

[0074] In this embodiment, the automobile central control screen control system further includes a central control controller 40 and a central control display screen 50; the central control controller 40 also includes a central control touch chip;

[0075] It is understandable that the central control touch chip can be a part of the central control controller 40. The central control touch chip can identify the signal generated by the user touching the screen when using the central control display screen 50, and identify the position and pressure value of the user touching the central control display screen 50 based on the signal.

[0076] The passenger controller 20 is further configured to, upon receiving a pressing signal, determine whether the pressing signal is a signal of a preset pressing position, and if the pressing signal is a signal of the preset pressing position, activate the passenger control mode;

[0077] It should be understood that when the user uses the passenger display screen 30, he or she may not necessarily want to start the passenger control mode, but may also want to use some entertainment functions on the passenger display screen 30, such as singing, listening to music, opening and closing windows, adjusting the air conditioning vents, etc.

[0078] To further illustrate, there may be multiple preset pressing positions. When the user presses multiple preset positions simultaneously with a certain pressure, the pressing signal at this time is determined to be a pressing signal of the preset position.

[0079] In specific implementation, the preset positions can be the upper left and upper right, lower left and lower right places of the co-pilot display screen. When the user presses and holds the upper left and upper right, lower left and lower right places of the co-pilot with both hands respectively, after five seconds, the co-pilot will pop up a message box asking whether to control the central control touch. After clicking to confirm, the co-pilot control mode is started.

[0080] The host 10 is configured to send a power-off signal to the central controller 40 upon receiving a trigger signal;

[0081] It is understandable that the power-off signal may be a protocol signal between the host 10 and the central controller 40 . When the host 10 receives the trigger signal, it sends the power-off signal to the central controller 40 .

[0082] The central control controller 40 is used to disconnect the central control display screen 50 from the central control touch chip when receiving a power-off signal.

[0083] It is understandable that when the central control controller 40 receives the power-off signal, it controls the central control touch chip to no longer receive the signal sent by the central control display screen 50. Simply put, after the central control controller 40 receives the power-off signal, the user presses the central control display screen 50 at this time, and the entertainment equipment in the car will not generate corresponding operations.

[0084] It should be noted that starting the co-pilot control mode is not only for controlling through the co-pilot display screen 30 when the central control screen is completely unusable, but also for giving the passenger control of the vehicle entertainment equipment. It can also be used to avoid accidental touch of the central control and the co-pilot control conflict when the central control display screen 50 is damaged but can still receive touch screen signals.

[0085] It should be emphasized that the passenger controller 20 is also used to lock the central control display screen to the passenger display screen 30 when receiving and displaying the central control display screen;

[0086] It is determined whether the touch signal is a preset signal. If the touch signal is a preset signal, the central control display screen is not displayed on the passenger display screen 30.

[0087] When the passenger controller 20 receives the central control display screen, the central control display screen is fixed in the passenger display screen 30 to prevent the user from making confusing operations on the two control systems of the passenger display screen and the central control display screen 50 during operation. For example, if it is not fixed, it is possible to control music through the passenger display screen and control the air conditioning through the central control screen. The two sets of control strategies are transmitted in the passenger controller 20 at the same time, which can easily lead to the scrapping of the control system and system confusion.

[0088] This embodiment determines whether to enter the passenger control mode by obtaining the operator signal generated by the user when pressing the passenger display screen 30. At the same time, when entering the passenger control mode, the control ability of the central control display screen 50 over the car entertainment equipment is disconnected to avoid conflicts between the passenger control and the central control. The central control screen is fixed when displayed on the passenger display to avoid conflicts between the two control systems in the passenger controller 20. The vehicle entertainment equipment can be controlled more flexibly and accurately in the passenger display screen 30.

[0089] The embodiment of the present invention provides a car entertainment device control system, referring to Figure 3 , Figure 3 This is a structural diagram of a third embodiment of a car entertainment device control system according to the present invention.

[0090] In this embodiment, the co-pilot controller 20 further includes a co-pilot deserializer 21;

[0091] It is understandable that each display screen has a corresponding display screen, and the display screen of each display screen may have different clarity, different size, etc.

[0092] The host 10 is further configured to obtain the size of the passenger display screen 30 and compress the image of the central control display screen 50 according to the size of the passenger display screen 30 to obtain a compressed central control image;

[0093] It should be understood that when the size of the passenger display screen 30 is smaller than the size of the central control display screen 50, the image of the central control display screen 50 is compressed according to the size of the passenger display screen 30 and then sent to the passenger controller 20; when the size of the passenger display screen 30 is larger than the size of the central control display screen 50, the size of the central control display screen 50 is enlarged according to the size of the passenger display screen to obtain an enlarged central control image.

[0094] The host 10 is further configured to send the compressed central control screen to the passenger deserializer 21 via a low-voltage differential signal;

[0095] It is understandable that the low voltage differential signal may be an LVDS (Low Voltage Differential Signaling) signal (including a video signal and a communication signal).

[0096] The passenger deserializer 21 is configured to receive the low voltage differential signal, convert the low voltage differential signal into a bus communication signal, and send the bus communication signal to the passenger display screen 30 for display.

[0097] In the specific implementation, please refer to Figure 4 In the figure, the co-pilot controller 20 also includes a co-pilot host 22; and wherein, the central control controller 40 also includes a central control host 42 and a central control deserializer 41, wherein the host 10 also includes a host 10 central control serializer and a host 10 co-pilot serializer; further, it should be noted that the host 10 sends a video signal to the central control controller 40 / co-pilot controller 20 through the host 10 central control serializer / host 10 co-pilot serializer with a main line communication signal, wherein the video signal can be a MIPI_DSI (Mobile Industry Processor Interface-Digital Systems Information, MIPI-DSI is a serial interface used for display technology) video signal.

[0098] It should be noted that the MIPI_DSI video signal is transmitted between the host 10 and the host 10 co-pilot serializer / host 10 central control serializer through bus signals; the host 10 co-pilot serializer / host 10 central control serializer and the corresponding deserializer communicate through LVDS signals; the co-pilot deserializer 21 / central control deserializer 41 and the co-pilot host 22 / central control host 42 communicate through bus signals; the co-pilot host 22 and the central control host 42 also communicate through bus signals.

[0099] In this embodiment, when the passenger control mode is started, the central control display screen is adjusted according to the size of the passenger display screen 30 to obtain a screen suitable for the size of the passenger display screen 30, and the screen is sent to the passenger controller 20 through a low-voltage differential signal. The passenger controller 20 then sends the screen to the passenger display screen 30 through a bus signal, so that the passenger display screen 30 can display the central control display interface more appropriately and fittingly.

[0100] The embodiment of the present invention provides a car entertainment device control system, referring to Figure 5 , Figure 5 This is a structural diagram of a fourth embodiment of a car entertainment device control system according to the present invention.

[0101] In this embodiment, the passenger controller 20 further includes a passenger touch chip 23 .

[0102] The passenger touch chip 23 is used to obtain a touch signal of the passenger display screen 30 , obtain user control information according to the touch signal, and send the user control information to the central control controller 40 .

[0103] It is understandable that the touch signal may refer to a signal collected on the passenger passenger display screen 30 when the user touches the passenger passenger display screen 30 while using the passenger passenger display screen 30 .

[0104] It should be understood that the user may generate many touch signals when using the passenger display screen 30, but not all touch signals are valid. There may be signals generated by the user's unintentional touch, or there may be signals generated by other objects touching the passenger display screen 30.

[0105] It should be noted that the position and pressure value corresponding to the touch signal are matched with the display screen in the passenger display screen 30, and the user control information is obtained according to the matching result.

[0106] In a specific implementation, a plane rectangular coordinate system is established with the lower left corner of the co-pilot display screen as the origin. At this time, the co-pilot display screen is displayed on the co-pilot display screen, where the square formed by the upper left corner (2, 2) and the origin as the diagonal represents navigation. When the user uses the co-pilot display screen 30, the coordinates of the user when touching the co-pilot display screen 30 are obtained. When the touch coordinates are (1, 1), the user control information can be identified as navigation.

[0107] The central controller 40 is further configured to send the user control information to the host 10 upon receiving the user control information.

[0108] It is understandable that the user control information can be simply understood as the operation object that the user wants to perform on the passenger display screen 30; for example, turning on navigation, turning on music, opening the car window, entering settings, entering panoramic mode, etc.

[0109] The host 10 is further configured to receive the user control information and send a corresponding control screen to the passenger controller 20 according to the user control information.

[0110] It should be noted that the touch control in a normal car screen only controls one set of screens. Controlling the central control display content through the passenger screen can control the touch function of the central control screen by forwarding the passenger screen touch information to the controller of the central control screen.

[0111] It should be emphasized that the co-pilot controller 20 is also used to display control icons on the co-pilot display screen 30, so that the user can select in-vehicle entertainment options through the control icons; the control icons displayed on the co-pilot display screen can be dots similar to mouse arrows. When the co-pilot screen is slid and touched by a hand, the dots on the central control screen will move accordingly. After moving the dots to the corresponding position, click the co-pilot screen hard, and a synchronous click will appear at the central control dot position, allowing the central control to enter the corresponding interface and control the corresponding function.

[0112] The passenger seat touch chip 23 is also used to obtain the touch position and touch pressure of the current touch signal, and determine whether the touch position is consistent with the position of the control icon; if the touch position is consistent with the position of the control icon, it is determined whether the touch pressure meets the pressure condition; if the touch pressure meets the pressure condition, user control information is obtained according to the touch signal, and the user control information is sent to the central control host 42.

[0113] It's worth emphasizing that the central control unit 40 forwards the received passenger's touch information to the host 10. The host 10 then enters the corresponding screen and adjusts various in-vehicle functions based on the touch information transmitted by the central control unit 40. Finally, clicking the "X" in the upper right corner of the passenger's screen exits the passenger's control central control touch mode, which is a specific exit method.

[0114] Synchronously, when the co-pilot enters the central control touch mode, the host 10 will lock the screen transmitted to the co-pilot and will not change with the co-pilot's touch clicks. At the same time, the host 10 will configure the registers of the co-pilot controller 20 through the serializer-deserializer, allowing the co-pilot controller 20 to send the touch information collected by the co-pilot touch chip 23 to the central control controller 40 through the bus.

[0115] It should be noted that when the co-pilot has completed the control function of the central control entertainment device, or when the central control display screen 50 resumes normal use, it is necessary to exit the co-pilot control mode from the co-pilot display screen 30.

[0116] At this time, the passenger controller 20 obtains the touch signal on the passenger display screen 30. Simply put, in the passenger display screen 30, pressing different positions generates different signals, including a signal to start the passenger control mode, a signal to exit the passenger control mode, and a control signal to start / shut down various entertainment devices.

[0117] This embodiment sends the control signal collected by the passenger display screen 30 to the central control controller 40, and then transmits it to the central control display screen on the passenger display screen 30 through the host 10 of the central control controller 40. Under a set of control logic, the car entertainment equipment can be controlled by using the central control display screen through the passenger display screen 30, and the central control display screen is locked on the passenger display screen 30 in the passenger control mode, and the passenger control mode can be flexibly entered / exited. When the central control display screen 50 cannot be used, the car entertainment equipment can be controlled in a timely and flexible manner, thereby effectively improving the user experience and vehicle driving safety factor.

[0118] Reference Figure 6 , Figure 6 FIG. 1 is a flow chart of a first embodiment of a method for controlling a car entertainment device according to the present invention.

[0119] like Figure 6 As shown, the car entertainment device control method proposed in the embodiment of the present invention includes:

[0120] Step S10: The passenger controller determines whether the passenger control mode is currently activated according to the pressing signal, and sends a trigger signal to the host when the passenger control mode is activated;

[0121] Step S20: the host receives the trigger signal, and after receiving the trigger signal, transmits the central control display screen to the passenger display screen;

[0122] Step S30: The passenger controller receives and displays the central control display screen, obtains the touch signal on the passenger display screen, and controls the car entertainment equipment according to the touch signal.

[0123] In this embodiment, when the buttonless central control screen is damaged and cannot be operated, the passenger control mode is entered through the passenger touch screen to realize control of various entertainment functions of the car without affecting the use of the car's central control, improving the user experience and vehicle driving safety factor, and solving the problem that the touch screen is prone to accidental loss of control during the use of the central control screen, thereby making the entire car entertainment function unusable and seriously affecting the car driving experience.

[0124] In one embodiment, the automobile entertainment device control method further includes: when the co-pilot controller receives a press signal, it determines whether the press signal is a signal of a preset press position; if the press signal is a signal of a preset press position, the co-pilot control mode is started; when the co-pilot control mode is started, a trigger signal is sent to the host.

[0125] In one embodiment, the method for controlling a car entertainment device further includes: the host receiving the trigger signal, and after receiving the trigger signal, transmitting the central control display screen to the passenger display screen, including:

[0126] The host obtains the size of the co-pilot display screen, and compresses the image of the central control display screen according to the size of the co-pilot display screen to obtain a compressed central control image;

[0127] The host sends the compressed central control screen to the passenger deserializer via a low-voltage differential signal;

[0128] The co-pilot deserializer receives the low voltage differential signal, converts the low voltage differential signal into a bus communication signal, and sends the bus communication signal to the co-pilot display screen for display;

[0129] The host receives the trigger signal, and after receiving the trigger signal, transmits the central control display screen to the co-pilot display screen, further comprising:
