[0002] With the development of science and technology, in order to fully meet the needs of users, car companies have successively developed a large number of control functions for improving the user's driving environment. In the existing technology, one controller corresponds to one control function. When more and more control functions appear, the number of on-board display devices for displaying control functions and controllers for managing control functions also increases accordingly. Each controller needs to establish an independent communication line with the on-board display device, which increases the number of wiring harness interfaces in the vehicle. In addition, too many display screens easily cause users to be troubled by too much information and too much information, which is not conducive to the user's driving safety. The above design not only increases the design and development cost, but is also not conducive to later maintenance, causing unnecessary economic and energy losses to car companies, and to a certain extent, it is not conducive to the user's car experience. Summary of the invention

[0003] The main purpose of the present invention is to provide a method, device and computer-readable storage medium for centralized display control of multi-functional applications, aiming to solve the technical problems of unnecessary increase in design costs and difficulty in subsequent maintenance by automobile companies due to too many control functions.

[0004] To achieve the above object, the present invention provides a method for centralized display control of multifunctional applications, the method for centralized display control of multifunctional applications comprising the following steps:

[0006] After the functional signal is converted into a display image via the instrument host, the display image is received based on the LVDS interface;

[0007] The display image is displayed in a display area specified by the vehicle-mounted display device.

[0011] Optionally, after the step of obtaining the sub-controller corresponding to the operation signal, the method further includes:

[0012] Based on the main controller, a data transmission channel with the corresponding sub-controller is opened.

[0013] Optionally, after the step of sending the operation signal to the corresponding sub-controller, the method further includes:

[0014] The vehicle information corresponding to the operation signal is obtained through the corresponding sub-controller, and the vehicle information is converted into a signal source and output to the main controller as a functional signal.

[0015] Optionally, the step of converting the function signal into a display image via an instrument host and then receiving the display image based on an LVDS interface includes:

[0016] parsing the function signal based on the instrument host, and adding a position layout signal to the display image after converting the function signal into a display image through the instrument host;

[0017] The display image to which the position layout signal is added is received based on the LVDS interface.

[0018] Optionally, after the step of receiving the display image to which the position layout signal is added based on the LVDS interface, the method further includes:

[0019] Determining whether there is an original display image in the display area corresponding to the position layout signal based on the position layout signal;

[0020] If the display area corresponding to the position layout signal has an original display image, prompting the current user through a voice module whether to change the display image;

[0021] If the original display image does not exist in the display area corresponding to the position layout signal, the step of displaying the display image in the display area specified by the vehicle-mounted display device is performed.

[0022] Optionally, after the step of prompting the current user whether to change the displayed image through the voice module, the method further includes:

[0023] If the voice module recognizes that the current user confirms to change the display image, the original display image is stored in the pre-stored database, and then the step of displaying the display image in the display area specified by the vehicle-mounted display device is performed;

[0024] If it is recognized based on the voice module that the current user does not want to change the displayed image, no operation is performed on the original displayed image.

[0025] Optionally, after the step of displaying the display image in a designated display area, the method further comprises:

[0026] Prompt the current user through the voice module that the control function has been loaded, and identify whether the current user uploads a confirmation signal to confirm the current displayed image within the preset notification time;

[0031] The present invention realizes the effect of integrating the input and output lines of the sub-controllers by having the main controller receive the functional signals of other sub-controllers, thereby avoiding the problem of numerous vehicle wiring harness interfaces and increased design and development costs caused by the need for each sub-controller to establish an independent communication line with the display screen. By having the instrument host uniformly manage the generation of display images on the vehicle display device, it is avoided that different display image generation requires different generation modules, thereby avoiding unnecessary development costs. By displaying the display images corresponding to all functional signals on one vehicle display device, it is avoided that the vehicle development cost increases due to the need to arrange multiple vehicle display devices. At the same time, multiple vehicle display devices are prone to the problem of too complicated information reception during user driving, which is not conducive to driving safety and effective communication of vehicle information. Under the condition of numerous control functions, it is possible to reduce the design cost and ensure the stability of the vehicle display device, which also improves the user's car experience to a certain extent.

[0038] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0039] The main solution of the embodiment of the present invention is: by adding a main controller to integrate numerous sub-controllers and integrate the development of vehicle-mounted display devices, the vehicle only needs to install one vehicle-mounted display device to realize the display image of functional signals, so that multiple different display images can be displayed in the same area of ​​the vehicle-mounted device, so that the information integration of the vehicle-mounted display device is high, and efficient communication of vehicle information is achieved.

[0040] In the prior art, each sub-controller needs to establish a separate communication line with the on-board display device, which not only makes the vehicle's wiring harness interfaces numerous, but also increases the number of on-board display devices, thereby increasing the cost of early design and development for automobile companies. At the same time, too many on-board display devices are not conducive to the effective transmission of vehicle information.

[0041] The present invention provides a solution, which enables automobile manufacturers to realize efficient display and control of vehicle-mounted multifunctional applications by only installing a single vehicle-mounted display device on the vehicle, effectively reducing the initial design and development costs of the automobile manufacturers. At the same time, a single vehicle-mounted display device can display different information in a centralized manner, avoiding the situation where the vehicle information is too dispersed, efficiently conveying the vehicle information, and ensuring the driving safety of users.

[0042] like Figure 1 As shown, Figure 1 It is a schematic diagram of the terminal structure of the hardware operating environment involved in the embodiment of the present invention.

The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0045] Optionally, the multifunctional application centralized display control device may also include a camera, an RF (Radio Frequency) circuit, a sensor, an audio circuit, a WiFi module, and the like.

Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display screen according to the brightness of the ambient light, and the proximity sensor may turn off the display screen and / or backlight when the mobile terminal is moved to the ear. As a type of motion sensor, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile terminal (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; of course, the mobile terminal can also be equipped with other sensors such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., which will not be repeated here.

[0060] The step of receiving the display image based on the LVDS interface after converting the function signal into the display image via the instrument host comprises: parsing the function signal based on the instrument host, and adding a position layout signal to the display image after converting the function signal into the display image via the instrument host;

[0061] The display image to which the position layout signal is added is received based on the LVDS interface.

[0070] After the step of displaying the display image in the designated display area, the voice module prompts the current user that the control function has been loaded, and identifies whether the current user has uploaded a confirmation signal for confirming the current display image within a preset notification time;

[0071] If the current user uploads a confirmation signal for confirming the currently displayed image within the preset notification time, no operation is performed on the data transmission channel of the corresponding sub-controller;

[0072] If the current user does not upload a confirmation signal to confirm the currently displayed image within the preset notification time, the main controller is controlled to close the data transmission channel with the corresponding sub-controller.

[0073] Reference Figure 2 An embodiment of the present invention provides a method for centralized display control of multifunctional applications, the method for centralized display control of multifunctional applications comprising:

[0074] Step S10, based on the main controller receiving a function signal sent by the sub-controller to open the data transmission channel;

[0075] It should be noted that the executor of this application is the vehicle-mounted display device.

[0076] The main controller is used not only to receive and transmit information, similar to the function of an information transfer station, but also to parse the received operation signals to determine which sub-controller to start the data transmission and communication.

[0077] Among them, there is only one main controller, which is used to integrate the functions of other sub-controllers, and there are several sub-controllers. In order to avoid the situation where too many vehicle wiring harness interfaces are caused by too many sub-controllers, which is not conducive to later maintenance, this application only realizes the management and connection of several sub-controllers by adding one main controller, thereby realizing the unification of vehicle wiring harness interfaces.

[0078] By receiving the function signal from the sub-controller that has opened the data transmission channel based on the main controller, the normal operation of the vehicle-mounted display device is achieved and the interference of other invalid function signals can be avoided.

[0079] Different sub-controllers are used to generate functional signals of different control functions, thereby realizing the display of vehicle information.

[0080] Step S20, converting the function signal into a display image via the instrument host, and receiving the display image based on the LVDS interface;

[0081] The instrument host is mainly used for the generation of display images. For example, the reversing image information, panoramic image information, control function icons, etc. on the vehicle display device are all generated based on the instrument host. The unified generation of display images through the instrument host can avoid the problem of excessive load on the vehicle display device caused by the addition of different display image modules, and the workload of early development and installation is too cumbersome.

[0082] Transmitting the generated display image to the on-board display device via the LVDS (Low Voltage Differential Signaling) interface can effectively reduce the high power consumption caused by electromagnetic interference during the transmission process and avoid unnecessary waste of vehicle performance resources.

[0083] Step S30: displaying the display image in a display area specified by the vehicle-mounted display device.

[0084] After the vehicle-mounted display device receives the display image, the display image converted by the function signals generated by different sub-controllers is displayed in different areas on the vehicle-mounted display device. Therefore, the received display image needs to be displayed in the designated display area to avoid a chaotic display area that causes the user to be unable to effectively receive vehicle information, thereby affecting the user's viewing experience when using the vehicle-mounted display device.

[0085] It should be noted that the vehicle-mounted display device also integrates the UI (User Interface Design, human-computer interaction) interface, making the implementation of operating functions more unified and efficient.

[0086] Optionally, after the step of displaying the display image in the designated display area in step S30, the method further includes:

[0087] Step A1, prompting the current user through the voice module that the control function has been loaded, and identifying whether the current user uploads a confirmation signal to confirm the current display image within a preset notification time;

[0088] After the display image is displayed in the display area corresponding to the vehicle-mounted display device, the vehicle-mounted display device will transmit the loaded signal to the voice module, so that the voice module can promptly prompt the user that the control function has been loaded, thereby avoiding the situation where the user fails to view the important vehicle information in time and misses it.

[0089] After the notification is completed through the voice module, the calculation of the notification duration is started, and it is identified whether the current user uploads a confirmation signal confirming the currently displayed image within the preset notification upload.

[0090] The confirmation signal may be a voice, an operation on a vehicle-mounted display device, or an operation to control the relevant control functions of the vehicle, etc. Any behavior that can be determined as the user's approval of the currently displayed control function is classified as a confirmation signal.

[0091] Step A2: if the current user uploads a confirmation signal for confirming the current displayed image within the preset notification time, no operation is performed on the data transmission channel of the corresponding sub-controller;

[0092] If it is recognized that the current user has uploaded a confirmation signal to determine the currently displayed image within the preset notification time, the main controller is controlled to maintain the connection with the data transmission channel of the sub-controller corresponding to the control function, so as to avoid the closure of the data transmission channel causing the display image to be updated untimely, and thus resulting in discontinuity in the displayed vehicle information.

[0093] Step A3: If the current user does not upload a confirmation signal to confirm the currently displayed image within a preset notification time, the main controller is controlled to close the data transmission channel with the corresponding sub-controller.

[0094] If it is identified that the current user has not uploaded confirmation information confirming the currently displayed image within the preset notification time, it means that the current user does not need the vehicle information shown in the currently displayed image. Therefore, in order to avoid the situation where other important display images cannot be displayed in time due to too many open data transmission channels, the main controller needs to be controlled to close the data transmission channel of the sub-controller corresponding to the confirmation signal that has not been uploaded.

[0095] In this embodiment, the integration of multiple sub-controllers is achieved by adding a main controller, the unification of the vehicle wiring harness interface is achieved, and the conversion of the display image is achieved based on the instrument host, so as to avoid the problems of excessive load on the vehicle display device caused by the addition of different display image modules and the excessive workload of the early development and installation. By displaying the corresponding display image in the display area corresponding to the vehicle display device, the confusion of the display area caused by the disordered display layout is avoided, and the design cost is reduced in the case of numerous control functions, and the stability of the vehicle display device is guaranteed, which also improves the user experience of the car to a certain extent.

[0096] Further, see Figure 3 An embodiment of the present invention provides a method for centralized display control of multifunctional applications. Based on the embodiment shown in step S10 above, before the step of receiving the function signal sent by the sub-controller specified by the current user based on the main controller, the method further includes:

[0097] Step S11, receiving an operation signal uploaded by the current user based on the main controller;

[0098] It should be noted that the operation signal can be uploaded by the user through operating the on-board display device, such as the operation signal displaying the vehicle status uploaded by the user by clicking the control function that displays the vehicle status, etc. At the same time, the operation signal can also be automatically activated by the user controlling the vehicle, such as the operation signal displaying the reversing image that is automatically activated when the user controls the vehicle to reverse, etc. It can also be an operation signal uploaded by the user through voice, and so on. This realizes the timely reception of different types of operation signals and the feedback of corresponding display images, avoiding the situation where a single operation signal reception method cannot fully meet user needs.

[0099] Step S12: After parsing the operation signal, obtain the sub-controller corresponding to the operation signal, and send the operation signal to the corresponding sub-controller.

[0100] After parsing the received operation signal, the sub-controller corresponding to the operation signal can be obtained, and then the operation signal can be sent to the corresponding sub-controller to achieve timely generation of functional signals.

[0101] Optionally, after the step of obtaining the sub-controller corresponding to the operation signal in step S12, the method further includes:

[0102] Step B: based on the main controller, open a data transmission channel with the corresponding sub-controller.

[0103] After parsing the operation signal and obtaining the corresponding sub-controller, it is also necessary to open the data transmission channel between the main controller and the sub-controller to achieve timely sending of the operation signal and timely receiving of the function signal.

[0104] Optionally, after the step of sending the operation signal to the corresponding sub-controller in step S12, the method further includes:

[0105] Step C, obtaining the vehicle information corresponding to the operation signal through the corresponding sub-controller, and converting the vehicle information into a signal source as a functional signal and outputting it to the main controller.

[0106] In this embodiment, by enriching the methods of receiving operation signals, the reception barriers caused by a single method of receiving operation signals are avoided, so that user needs cannot be fully met. By sending the operation signals to the corresponding sub-controllers, the timely generation of function signals is achieved.

[0107] Further, see Figure 4 An embodiment of the present invention provides a method for centralized display control of multifunctional applications. Based on the embodiment shown in step S20 above, the step of converting the function signal into a display image via the instrument host and then receiving the display image based on the LVDS interface includes:

[0108] Step S21, parsing the function signal based on the instrument host, and after converting the function signal into a display image through the instrument host, adding a position layout signal to the display image;

[0109] Step S22, refer to Figure 5 , receiving the display image to which the position layout signal is added based on the LVDS interface.

[0110] After receiving the function signal, the instrument host not only converts the function signal into a display image, but also needs to parse the function signal to obtain the position coordinates of the display area of ​​the display image on the vehicle display device, so as to realize the orderly display of the display image.

[0111] The position layout signal refers to the position coordinates of the display area. Figure 5 As shown, the display area of ​​the display images of vehicle driving and vehicle faults at position coordinate 1, the display areas of the display images of ADAS (Advanced Driving Assistance System) intelligent driving faults and status at position coordinate 2 and position coordinate 3, the display area of ​​the display image of ADAS intelligent driving status vehicle model information at position coordinate 4, the display area of ​​the display image of vehicle driving information at position coordinate 5, the display area of ​​the display image of vehicle status information at position coordinate 6, and the display area of ​​the display image of panoramic images, reversing images, and vehicle entertainment systems at position coordinate 7.

[0112] Optionally, after the step of receiving the display image to which the position layout signal is added based on the LVDS interface in step S22, the method further includes:

[0113] Step D1, judging whether there is an original display image in the display area corresponding to the position layout signal based on the position layout signal;

[0114] It is determined by the received position layout signal whether the original display image already exists at the position coordinates of the position layout signal, so as to avoid the situation where the original display is suddenly replaced, thereby causing a poor user experience.

[0115] Step D2, if the display area corresponding to the position layout signal has an original display image, prompting the current user through a voice module whether to change the display image;

[0116] If it is detected that the original display image exists at the position coordinates corresponding to the position layout signal, the vehicle-mounted display device needs to prompt the user through the voice module that there is a display image in the display area, and then guide the user to determine whether to change the display image.

[0117] Step D3: If the original display image does not exist in the display area corresponding to the position layout signal, the step of displaying the display image in the display area specified by the vehicle-mounted display device is performed.

[0118] If it is detected that the original display image does not exist at the position coordinates corresponding to the position layout signal, the received display image is directly displayed in the display area corresponding to the vehicle-mounted display device.

[0119] Optionally, after the step of prompting the current user whether to change the displayed image through the voice module in step D2, the method further includes:

[0120] Step E1, if the voice module recognizes that the current user confirms to change the display image, the original display image is stored in the pre-stored database, and then the step of displaying the display image in the display area specified by the vehicle display device is performed;

[0121] Step E2: If it is recognized based on the voice module that the current user does not want to change the displayed image, no operation is performed on the original displayed image.

[0122] In this embodiment, a position layout signal is added to the display image so that the display image can be displayed in the corresponding display area, thereby realizing an orderly layout of the vehicle-mounted display device and further improving the user's viewing experience. By judging whether the original display image already exists at the position coordinates corresponding to the position layout signal, the situation in which the original display is suddenly replaced, thereby causing a poor user experience, can be avoided. By judging whether the user confirms the operation of replacing the display image, the situation in which the original display image is suddenly replaced by the current important display image, thereby causing a poor user experience, can be avoided.
