The user interface 1003 can include a display, an input unit such as a keyboard, and can also include a standard wired interface and a wireless interface. The network interface 1004 can optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wi-Fi) interface). The memory 1005 can be a high-speed random access memory (RAM) memory or a stable non-volatile memory (NVM), such as a disk memory. The memory 1005 can also be a storage device independent of the aforementioned processor 1001.
[0051] Those skilled in the art can understand that Figure 1 the structure shown in the above description does not constitute a limitation on the vehicle rear-row display screen control device, and can include more or fewer components than those shown, or combine certain components, or different component arrangements.
[0052] As shown in Figure 1 , the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a vehicle rear-row display screen control program.
[0053] In the vehicle rear-row display screen control device shown in Figure 1 , the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the vehicle rear-row display screen control device of the present application can be arranged in the vehicle rear-row display screen control device, and the vehicle rear-row display screen control device calls the vehicle rear-row display screen control program stored in the memory 1005 through the processor 1001, and executes the vehicle rear-row display screen control method provided by the embodiment of the present application.
[0054] The embodiment of the present application provides a vehicle rear-row display screen control method, which refers to Figure 2 , Figure 2A flowchart of a first embodiment of a vehicle rear row display screen control method.
[0055] In this embodiment, the vehicle rear row display screen control method comprises the following steps:
[0056] Step S10: When the rear row display screen inputs a correct management password, the mode of the rear row display screen is switched to a management mode.
[0057] It can be understood that the vehicle has front row display screens and a rear row display screen, and each front row display screen corresponds to a front row control interface and a front row control, and the rear row display screen corresponds to a rear row control interface and a rear row control.
[0058] It can be understood that the management password can be characters, fingerprints, faces, voices, etc. When the management password input by the user is verified by the entertainment host and is consistent with the preset management password, it is determined that the management password input by the user is a correct management password.
[0059] It should be understood that the execution subject of this embodiment is an entertainment host, which is respectively connected with the front row display screen and the rear row display screen, and can include a system on chip (SOC), a front row serializer, and a rear row serializer. The SOC outputs two-way high-definition video signals into the serializer, and simultaneously communicates with the front row / rear row serializer through an inter-integrated circuit (IIC). The serializer outputs low-voltage differential signaling (LVDS) through a wire harness and is respectively connected to the front row display screen and the rear row display screen.
[0060] It should be noted that the rear row display screen can have two modes: one is a normal mode, in which the user can use all functions of the rear row control interface of the rear row display screen; and the other is a management mode, in which the user actively inputs a correct management password from the rear row display screen, and the mode of the rear row display screen is switched from the normal mode to the management mode. The front row display screen can also have two modes: one is a normal mode, in which the front row display screen is always in the normal mode when the rear row display screen does not enter the management mode, and the vehicle driver can control the functions in the front row control interface through the front row display screen; and the other is a lock mode, in which the front row display screen is passively switched to the lock mode when the rear row display screen is switched to the management mode, and the driver cannot control the vehicle from the front row display screen.
[0061] It is emphasized that if the user inputs a wrong or no management password on the rear display screen, the front display screen and the rear display screen can display different contents respectively, and the entertainment host respectively acquires the touch signals on the front display screen and the touch signals on the rear display screen. The front media resource and the rear media resource are obtained according to the touch signals on the front display screen and the touch signals on the rear display screen, and the front media resource and the rear media resource are transmitted back to the corresponding display screen for display.
[0062] It is noted that the front touch control chip or the rear touch control chip collects the coordinate point when the user touches the front display screen or the rear display screen, determines the corresponding media resource of the coordinate point in the central control interface, and sends the media resource to the serializer through the Inter-Integrated Circuit (IIC).
[0063] It is further emphasized that the vehicle interior includes the entertainment host part and the front central control and the rear central control, and the specific reference can be made to Figure 3 The entertainment host includes a System on Chip (SOC), a front serializer and a rear serializer; the front central control part includes a front deserializer, a Microcontroller Unit (MCU) and a front touch control chip; and the rear central control includes a rear deserializer and a rear touch control chip.
[0064] When the rear is not in the management mode, the user clicks or touches the front display screen / rear display screen, the front touch control chip / rear touch control chip collects the signal of the user clicking on the display screen, converts the signal into an IIC signal internally and transmits the IIC signal to the MCU, the MCU analyzes the touch control chip IIC signal, transmits the signal to the front / rear deserializer through another ICC on the MCU, the deserializer transmits the corresponding touch signal to the entertainment host according to the LVDS signal link, and the entertainment host transmits the picture clicked into the front display screen / rear display screen after receiving the corresponding touch signal.
[0065] It is further emphasized that the front row media resource and the rear row media resource obtained according to the touch signal on the front row display screen and the touch signal on the rear row display screen can be obtained according to the coordinate position of the touch signal on the display screen and the matching of the central control interface, so as to confirm which multimedia resource in the central control interface the touch signal corresponds to. For example, when in the normal mode, the upper left corner of the front row central control interface is the navigation block, the lower left corner is the contact block, the middle is the music block, the upper right is the Bluetooth block, and the lower right is the other block. When the coordinate of the touch signal is detected to be in the middle, it is identified that the user starts the music block, and the entertainment host feeds back the interface corresponding to the music block to the front row display screen or directly plays the corresponding music media resource.
[0066] It is emphasized that in the normal mode, the front row display screen and the rear row display screen can respectively display, and the front row and the rear row can more flexibly realize the corresponding functions, and display different pictures without affecting each other.
[0067] Step S20: When the rear row display screen of the vehicle is in the management mode, a locking signal is sent to the front row display screen of the vehicle, so that the front row display screen is in the locking mode.
[0068] It can be understood that the locking signal includes a front row display screen power-off signal and a front row display screen touch chip power-off signal.
[0069] It should be noted that when the rear row display screen of the vehicle is in the management mode, the entertainment host sends the front row display screen power-off signal and the front row display screen touch chip power-off signal to the front row display screen. The front row central control will close the power supply of the touch chip according to the pre-set protocol, so that the front row central control screen touch is invalid, the front row central control backlight power supply is closed, and the front row central control screen is black, so as to achieve the front row display screen in the locking mode. The pre-set protocol can be understood as the relationship between the closing signal and the closing of the front row display screen power supply, or the relationship between the power-off signal and the closing of the front row display screen touch chip power supply.
[0070] It is emphasized that after the entertainment host receives the correct management password input by the rear row display screen, the front row central control screen backlight power supply and the front row central control screen touch chip power-off signal are transmitted to the front row serializer through IIC. The front row serializer transmits the LVDS signal to the deserializer, the deserializer converts the ICC signal to the MCU, the MCU reads the ICC information, and according to the pre-set protocol, the power supply of the touch chip is closed, so that the front row central control screen touch is invalid, the front row central control backlight power supply is closed, and the front row central control screen is black, and the locking mode is entered.
[0071] In a specific implementation, when the user in the back row wants to dial the phone of a contact through the front row central control, the user can input a management password in the back row display screen, and the back row display screen enters a management mode. The back row display screen can display the front row central control interface. At this time, the user can select multimedia resources in the front row central control interface through the back row display screen.
[0072] When the back row display screen of the vehicle is in the management mode, a lock signal is sent to the front row display screen of the vehicle, so that the front row display screen is in a lock mode.
[0073] Step S30: The front row central control interface is sent to the back row display screen. According to the selection of the user in the back row display screen, a trigger signal is obtained.
[0074] It can be understood that the trigger signal can be a signal generated when the user touches the front row central control interface and sent to the entertainment host to obtain.
[0075] For example, the entertainment host sends the front row central control interface to the back row display screen. The user in the back row selects a navigation interface from the back row display screen. The signal generated when the user selects the navigation interface is sent to the entertainment host through the back row display screen to obtain the trigger signal.
[0076] It should be understood that the size, model and display ratio of the front row display screen and the back row display screen can be different.
[0077] It should be noted that when the front row display screen is in the lock mode, in order to make it more convenient for the user in the back row to use the front row central control interface in the back row display screen, the front row central control interface can be adjusted according to the size, model and display ratio of the back row display screen before being sent to the back row display screen, so as to be more consistent with the size, model and display ratio of the back row display screen.
[0078] The front row central control interface is adjusted according to the display ratio of the back row display screen to obtain an adjusted front row central control interface.
[0079] It should be noted that the display ratio of the front row display screen and the back row display screen is adjusted, so that the front row central control interface in the back row display screen is more consistent with the use habit of the user in the back row, improves the user experience, and only one set of UI interface is used at this time, reducing the host computing amount.
[0080] It should be noted that the user in the back row of the vehicle listens to music in the back row display screen, but at this time, a part of work needs to be connected with Bluetooth for processing. The user in the back row can input a management password to make the back row display screen enter a management mode. After receiving the front row central control interface, the user can select a Bluetooth control block in the front row central control interface in the back row display screen.
[0081] Step S40: determining a target media resource according to the trigger signal, and sending the target media resource to the front-row display screen to make the front-row display screen display the target media resource.
[0082] It can be understood that the target media resource can be content that the user wants to display on the display screen, can be content of an APP (navigation, Bluetooth, etc.), can be an audio segment (music, radio, etc.), can be a video segment (vehicle body monitoring video, etc.), or can be an image (management image, etc.).
[0083] It can be understood that the rear-row control interface includes an exit casting button; the exit casting button can be used to cast content that the rear-row user wants to display in the front-row control interface to the front-row display screen in the management mode, and if casting is stopped, the exit casting button can be clicked to stop casting the media resource to the front-row display screen.
[0084] It is worth noting that when the rear-row display screen enters the management mode, the entertainment host only needs to use one set of human-computer interaction interface, which to some extent simplifies the data operation amount of the entertainment host.
[0085] It is emphasized that when the exit casting button is started, the rear-row display screen switches from the front-row control interface to the rear-row control interface and continuously sends the target media resource to the front-row display screen; a touch signal of the user on the rear-row control interface is collected, and a corresponding media resource is sent to the rear-row display screen according to the touch signal.
[0086] It is further emphasized that continuously sending the target media resource to the front-row display screen can be understood as that when the exit casting button is started, after the rear-row display screen switches from the front-row control interface to the rear-row control interface, the front-row display screen still continuously displays the media resource transmitted to the front-row display screen. For example, the rear-row display screen enters the management mode, receives the front-row control interface, selects a navigation application from the front-row control interface, and transmits the image of the navigation application to the front-row display screen; if other applications such as music and Bluetooth are to be transmitted to the front-row display screen, the selection can continue, and if the transmission is not to continue, the exit transmission button can be pressed; after the exit transmission button is started, the operation of the rear-row user on the rear-row display screen will no longer be transmitted to the front-row display screen, and the front-row display screen can continuously display the content of the navigation and will not exit; if the rear-row user exits the management mode, the front-row display screen will no longer continuously display the media resource.
[0087] In a specific implementation, the APP image (map navigation, etc.) to be displayed by the front-row control is output by the rear-row screen by clicking the transmission button on the rear-row display screen; when there is no next time of clicking the suspended transmission button, the various operations of the user on the rear-row display screen will not be cast to the front-row display screen, and the entertainment host will always cast the image on the APP to the front-row display screen.
[0088] It should be noted that after the rear row enters the management mode, the front row only displays the content specified by the rear row user, and the rear row can perform other operations, and only the rear row display screen displays the privacy protection of the user.
[0089] The embodiment makes the front row display screen enter the lock mode while the rear row display screen enters the management mode, and determines the display content of the front row display screen through the rear row display screen, so that the rear row passenger can control the entertainment operation of the whole vehicle, controls the display content of the front and rear rows of the vehicle, and improves the overall control feeling of the user on the vehicle.
[0090] Reference Figure 4 , Figure 4 The flowchart of the second embodiment of the vehicle rear row display screen control method of the application is shown.
[0091] Based on the above-mentioned first embodiment, the vehicle rear row display screen control method of the embodiment further comprises the following steps after step S40:
[0092] Step S50: acquiring real-time images collected by the vehicle rear camera, identifying the real-time images, and sending the real-time images to the rear row display screen for display.
[0093] It can be understood that the vehicle rear camera can be on the left side or the right side, or there can be real-time images collected by left and right cameras at the same time. If there are real-time images collected by left and right cameras at the same time, the real-time images of the left and right cameras will be displayed on the rear row display screen at the same time.
[0094] It should be understood that acquiring real-time images collected by the vehicle rear camera can be in the scene where the vehicle stops driving and waits for the passengers in the vehicle to get off. When the vehicle stops driving, the real-time images of the camera are acquired.
[0095] It should be noted that the real-time images collected by the camera are identified by the entertainment host, in order to identify whether there are pedestrians and vehicles and other obstacles behind the vehicle.
[0096] It should be further noted that the real-time images are sent to the rear row display screen at the same time as the identification of the real-time images by the entertainment host. The rear row user can determine whether the door can be opened and whether there is a safety hazard through the real-time images displayed on the rear row display screen.
[0097] Step S60: when it is identified that there are obstacles in the real-time images, the door is locked.
[0098] It can be understood that the identification of whether there are obstacles in the real-time images by the entertainment host can be to avoid accidents caused by sudden opening of the door in the presence of obstacles.
[0099] It should be understood that when no obstacle is identified in the real-time image, the door will not be locked, and the user can directly open the door.
[0100] Step S70: When the unlocking condition is met, the door is unlocked, wherein the unlocking condition at least includes receiving an internal unlocking signal or receiving an external unlocking signal.
[0101] It should be noted that when the entertainment host receives an internal unlocking signal or an external unlocking signal, it is determined that the unlocking condition is met, and the door can be unlocked.
[0102] It should be noted that the driver manually starts the door opening button to unlock the door, and the signal generated by the door opening button is an internal unlocking signal, and the door is unlocked.
[0103] When the obstacle in the image is identified to disappear or there is no obstacle, an internal unlocking signal can be obtained, and the door is unlocked.
[0104] When the user triggers the door opening button in the rear display screen, an internal unlocking signal is generated, and the door is unlocked.
[0105] When the electronic door is opened from the outside, an external unlocking signal is generated, and the door is unlocked. It can be understood that when the vehicle is stopped and someone needs to get on the vehicle, but the situation of continuously detecting obstacles behind the vehicle is avoided, if someone wants to open the door from the outside, an external unlocking signal will be generated.
[0106] The embodiment of the present application displays the real-time image of the rear side collected by the camera on the rear display screen, so that the rear user can determine whether the door can be opened to leave the vehicle, and intelligently identifies whether there are objects such as vehicle pedestrians in the image. If there are objects, the rear door is locked, and the user can also be unlocked and opened by a plurality of internal unlocking signals and external unlocking signals, thereby avoiding the situation that the rear user does not pay attention and opens the door to cause accidental injury.
[0107] In addition, the embodiment of the present application also provides a storage medium, and the storage medium stores a vehicle rear display screen control program. When the vehicle rear display screen control program is executed by a processor, the steps of the vehicle rear display screen control method described above are implemented.
[0108] Reference Figure 5 , Figure 5 is a structure block diagram of the first embodiment of the vehicle rear display screen control device of the present application.
