Description

Technical Field

[0001] The present invention belongs to the technical field of smart cockpits, and in particular, the present invention relates to a vehicle-mounted multi-screen linkage system, a use method and a vehicle. Background Art

[0002] In the existing car machine intelligent cockpit, the screen has developed from a single screen to multiple screens. The current car screens are generally equipped with 4 to 12 screens. The interface content or display content between screens only considers the migration between the main screen device and the secondary screen device, the content migration between the secondary screen and the secondary screen device, and the content migration from the secondary screen to the main screen device. It not only does not take into account driving safety, permission settings, but also does not take into account the convenience of user operation.

[0003] With the rapid development of intelligent cockpit technology, the number and complexity of in-vehicle screens are increasing. The current design of in-vehicle screen content migration has some shortcomings, especially in terms of driving safety, permission settings, and user convenience. The current screen content migration design focuses on the content transfer between the main screen and the sub-screen, but rarely considers the impact of this migration on the driver's attention. Content migration between sub-screens and content migration from the sub-screen to the main screen may distract the driver, thereby increasing the risk of accidents.

[0004] The current in-vehicle screen content migration system often lacks detailed permission management. Drivers and passengers may not be able to flexibly control the display and migration of screen content according to their needs.

[0005] The current screen content migration design is often too complicated and difficult for users to quickly understand and operate. Content migration between secondary screens and content migration from secondary screen to main screen may lack intuitive operation interface and feedback mechanism.

[0006] It is hoped to provide an improved in-vehicle multi-screen linkage system. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a vehicle-mounted multi-screen linkage system, the purpose of which is to improve the convenience of operation and realize the authority partition management.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: a vehicle-mounted multi-screen linkage system, including a vehicle-mounted system and an authority setting module, the vehicle-mounted system includes a plurality of vehicle-mounted screens, after the vehicle-mounted screen requesting linkage is activated, one or more linked vehicle-mounted screens are selected for linkage;

[0009] The permission setting module is configured to determine the permission level of the vehicle-mounted screen.

[0010] The permission levels set by the permission setting module can be divided into first-level permission, second-level permission, third-level permission...N-level permission from high to low, and each level of permission is divided into upper area, middle area and lower area.

[0011] The plurality of screens include a main screen and a sub-screen, the main screen and the sub-screen are in the same local area network, one main screen is provided, and at least one sub-screen is provided.

[0012] The permission setting module sets the permission level of the main screen to the first level permission, and enables the main screen to have the ability to set the permission level for the slave screen.

[0013] The vehicle-mounted multi-screen linkage system also includes a linkage setting module, which is configured to provide a selection of linkage modes, including a forced linkage mode and a free linkage mode, and the free linkage mode is further divided into inquiry linkage, direct linkage and rejection linkage.

[0014] The vehicle-mounted multi-screen linkage system also includes a linkage selection module, which is configured such that when one of the vehicle-mounted screens is activated and the vehicle-mounted screen is in a link request state, by swiping along a selected swiping direction on the vehicle-mounted screen, the vehicle-mounted screen is used as the origin and linkage is performed toward another vehicle-mounted screen pointed to by the swiping direction.

[0015] The vehicle-mounted multi-screen linkage system also includes a multi-screen selection module, which is configured to control the linkage of multiple vehicle-mounted screens and can select a linkage mode.

[0016] The linkage mode includes a synchronous linkage mode and a crossing linkage mode.

[0017] The present invention also provides a method for using the vehicle-mounted multi-screen linkage system, comprising:

[0018] The permission setting module sets the permission level of the vehicle-mounted screen;

[0019] Among the in-vehicle screens, the in-vehicle screens with the first level of authority have 8 swipe directions, and the in-vehicle screens with other authority have 3 to 5 swipe directions;

[0020] Among the vehicle screens, when one of the vehicle screens is activated and is in a link request state, swiping along a selected swiping direction on the vehicle screen will link to another vehicle screen pointed to by the swiping direction with the vehicle screen as the origin.

[0021] The present invention also provides a vehicle, comprising the vehicle-mounted multi-screen linkage system.

[0022] The in-vehicle multi-screen linkage system of the present invention can achieve the function of linkage and sharing between screens by setting permission levels and managing permissions by partitioning, while respecting the wishes of individuals to the greatest extent. The operation between multiple screens can make the use of screens in the cabin more flexible and increase the interaction between passengers in the car. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] like Figures 1 to 9 As shown, an embodiment of the present invention provides a vehicle-mounted multi-screen linkage system, including a vehicle-mounted system and a permission setting module. The vehicle-mounted system includes a plurality of vehicle-mounted screens, and all the vehicle-mounted screens are in the same local area network to ensure that they can communicate and transmit data. After the vehicle-mounted screen requesting linkage is activated, one or more linked vehicle-mounted screens are selected for linkage;

[0036] The vehicle-mounted screen is configured to identify at least one vehicle-mounted screen that needs to be linked by identifying the swiping direction and / or swiping technique of the operator. The swiping direction refers to several operation directions preset on the vehicle-mounted screen, and the swiping technique refers to the swiping path on the vehicle-mounted screen, including swiping along a straight line and swiping along an arc. It can be a simple swipe along a straight line or a complex swipe along an arc. Swipe along a straight line is usually used to select basic linked operations or screens, while swiping along an arc may be used to perform more complex linked tasks or select a specific screen combination. Different swiping techniques can correspond to different linked functions or screen selection logic, thereby providing users with more abundant operation options.

[0037] Specifically, when a certain in-vehicle screen (which we call a "request screen") is activated for linkage operation during the operation of the vehicle system, the system begins to enter linkage mode. In linkage mode, the request screen will provide an interface for the user to select one or more other in-vehicle screens for linkage. The selection method can be various, through the rotation and change of the swiping direction and swiping technique on the in-vehicle screen.

[0038] An innovative point of an embodiment of the present invention is that the in-vehicle screen can determine the screen that needs to be linked by identifying the swiping direction and swiping technique of the operator. For example, the operator can swipe left on the request screen, and the system may interpret it as selecting the in-vehicle screen on the left for linkage; or select multiple screens through a specific swiping technique. This mode of operation can improve the user experience: selecting the linked screen through intuitive swiping operations makes the operation simpler and more intuitive. It is also flexible: users can select one or more screens for linkage as needed to meet different usage scenarios and needs. At the same time, since all screens are in the same local area network, screens can be easily added or removed without affecting the overall functionality of the system.

[0039] The permission setting module is configured to determine the permission level of the vehicle screen. The permission levels set by the permission setting module can be divided into first-level permission, second-level permission, third-level permission...Nth-level permission, N is a positive integer, and each permission level is divided into three sub-areas: upper area, middle area and lower area. Different areas further refine the differences in operation permissions based on the permission level.

[0040] The vehicle-mounted multi-screen linkage system of an embodiment of the present invention also includes a linkage setting module, which is configured to provide a selection of linkage modes, including a forced linkage mode and a free linkage mode, and the free linkage mode is further divided into inquiry linkage, direct linkage and rejection linkage.

[0041] Forced linkage means that a car screen with a high authority level can forcibly link with other car screens with relatively low authority levels without the consent of the car screens with low authority levels.

[0042] Inquiry linkage means that the vehicle screens at the same or relatively higher authority level can be linked freely. That is, if one vehicle screen wants to link with other vehicle screens, it needs to ask and obtain consent from other vehicle screens before it can link. If they do not agree, linkage cannot be performed.

[0043] Direct linkage means that the in-vehicle screens at the same or relatively higher authority level can be linked freely. That is, if one in-vehicle screen wants to link with other in-vehicle screens with the same authority level, the other in-vehicle screens can choose to link directly, that is, when receiving a link request asking for linkage, it is directly assumed to agree to the linkage.

[0044] Rejecting linkage means that when a car screen at the same or relatively lower authority level receives a link request from other car screens asking for linkage, it will default to rejecting linkage and will not pop up an inquiry interface to disturb the user of that screen.

[0045] In the embodiment of the present invention, the plurality of screens include a main screen and a secondary screen, the main screen and the secondary screen are in the same local area network, one main screen is provided, and at least one secondary screen is provided. The main screen is the vehicle screen operated by the main driver's seat, and the secondary screens include the vehicle screen operated by the co-driver's seat, the vehicle screen operated by the rear seats (the rear seats of 4-seat and 7-seat models), the roof projection screen, and an external screen connected to the vehicle system through a signal.

[0046] The permission setting module sets the permission level of the main screen to the first level, which is the highest permission level in the entire vehicle screen system, and enables the main screen to set the permission level for the secondary screen. The main screen can set the permission level of other secondary screens to the first level. The secondary screen with the first level permission can enjoy all the operation permissions of the main screen, but has no right to set the direction permission for the main screen, which ensures the core position and operational independence of the main screen in the system.

[0047] The linkage between the car screen with high-level authority and the car screen with low-level authority corresponds to forced linkage, the linkage between the car screens with upper-level authority corresponds to direct linkage, the linkage between the car screens with middle-level authority corresponds to inquiry linkage, and the linkage between the car screens with lower-level authority corresponds to rejection of linkage. The selection of upper, middle and lower level permissions can be the main screen to operate all the sub-screens, and each sub-screen can only select the upper, middle and lower level permissions for itself. For each level of permission setting, only the main screen and the sub-screen that is granted the first level of permission by the main screen can set permissions for other screens, but the permission level of the main screen cannot be changed.

[0048] In the embodiment of the present invention, by setting the permission setting module, the main screen can set and manage the permission levels for all the slave screens. This includes setting different levels of permissions and selecting different area divisions. Each slave screen can only select the upper, middle and lower level permissions for itself. This ensures that the slave screen has a certain degree of autonomy and flexibility in permission setting.

[0049] It is possible to implement permission setting restrictions: only the main screen and the secondary screen that is granted the first-level permission by the main screen can set the permissions of other screens. This further strengthens the core position of the main screen in permission setting and management.

[0050] The main screen permission protection can be achieved: the permission level of the main screen cannot be changed. This ensures the stability and security of the main screen in the entire car screen system.

[0051] The permission setting module provides an efficient, secure and flexible permission management mechanism for the vehicle screen system through detailed permission classification, regional division and linkage mode setting, which helps to improve the operating efficiency and user experience of the entire system.

[0052] The method for setting permissions and linkage methods is as follows:

[0053] The driver's screen (main screen) is the default first-level permission of the vehicle system, and has the ability to set permission levels for other secondary screens. In each permission level, the secondary screens in that permission level can be divided into any of the three areas of upper, middle and lower (the upper, middle and lower areas can be defined as attitude areas) and locked. After the secondary screen is locked, it cannot be customized on its own screen to select the position of the three areas of upper, middle and lower in its permission level;

[0054] If the main screen sets the permission level and divides the attitude area for the sub-screen, and the main screen does not lock the attitude area, other sub-screens can freely switch between the upper, middle and lower attitude areas within their permission levels (that is, the sub-screen can freely choose to be in the upper area, which means that when other screens with the upper level of permission and the same level of permission send a linkage link invitation to itself, it does not need to ask the user of the screen and can directly agree to the linkage request; it is in the middle area, which means that when other screens with the upper level of permission and the same level of permission send a linkage link invitation to itself, it needs to ask the user of the screen and can only establish a link after the user agrees to respond to the linkage request; it is in the lower area, which means that when other screens with the upper level of permission and the same level of permission send a linkage link invitation to itself, it does not need to ask the user of the screen and can directly reject the linkage request).

[0055] Through the above-mentioned setting methods of permissions and linkage modes, the vehicle system can flexibly manage permissions and linkage relationships between different screens. As the core of the system, the main screen has the highest permissions and the ability to set permissions for other screens; while the secondary screen can adjust its linkage response attitude according to the settings of the main screen and its own needs. This setting method not only ensures the stability and security of the system, but also improves the user's operating experience and freedom.

[0056] The swipe direction on the car screen can be set to a maximum of 8 to meet the linkage requirements of multiple screens. Figure 5 As shown, in an embodiment of the present invention, the eight swiping directions provided include top, bottom, left, right, top right, bottom right, bottom left and top left. In order to accurately distinguish each swiping direction, each swiping direction is represented as an angle relative to a certain reference direction (such as the right direction). For example, the right direction may be defined as 0 degrees, and then the top direction may be defined as 90 degrees, the bottom direction as -90 degrees (or 270 degrees), the left direction as 180 degrees, the right direction as 0 degrees, the top right direction as 45 degrees, the bottom right direction as -45 degrees (or 315 degrees), the bottom left direction as 225 degrees, and the top left direction as 135 degrees.

[0057] The vehicle-mounted multi-screen linkage system of the embodiment of the present invention further includes a screen activation module, which is configured to activate the vehicle-mounted screen to be linked, so that the vehicle-mounted screen is in a state of establishing a link request with other vehicle-mounted screens. In the embodiment of the present invention, the screen to be linked can be activated by a custom setting, and the custom activation method can be voice recognition activation, multi-finger touch screen activation, etc.

[0058] A screen activation module is set up to activate the in-vehicle screens to be linked, ensuring that they can receive and respond to linkage requests from other screens. The screen activation module implements the state transition of the screen: when the screen is activated, it will change from the standby or independent working state to the link request state, waiting to establish a linkage relationship with other screens. During operation, users can activate the in-vehicle screen through voice commands, which not only improves the convenience of operation, but also allows users to operate the screen without distraction during driving or riding. Users can use specific multi-finger gestures on the in-vehicle screen to activate the screen. For example, touch the screen with two fingers at the same time and slide, or draw a specific pattern on the screen with your fingers. This method provides another intuitive and easy-to-learn activation method, suitable for users who prefer or are more accustomed to touch operation. Users can choose voice recognition or multi-finger touch screen as the way to activate the screen through the screen activation module according to their preferences or needs. The screen activation module enables the system to flexibly respond to different usage scenarios and user needs, improve system flexibility and enhance user experience.

[0059] The vehicle-mounted multi-screen linkage system of an embodiment of the present invention also includes a linkage selection module, which is configured to, when one of the vehicle-mounted screens is activated and the vehicle-mounted screen is in a link request state, swipe along the selected swiping direction on the vehicle-mounted screen, and then linkage is performed with the vehicle-mounted screen as the origin to the other vehicle-mounted screen pointed to by the swiping direction.

[0060] Set up a linkage selection module, which is responsible for processing the linkage selection logic between vehicle screens. When one of the vehicle screens is activated and in the link request state, this module allows the user to select which vehicle screen to link with by swiping. The user can swipe along the selected swiping direction on the activated vehicle screen, and the linkage selection module will recognize this operation and initiate a linkage request to the other vehicle screen pointed to by the swiping direction, taking the vehicle screen as the origin.

[0061] In the embodiment of the present invention, in the vehicle screen, the vehicle screen with the first level of authority has 8 swiping directions, and the vehicle screen with other authorities has 3 to 5 swiping directions.

[0062] The car screen with the first level of permissions has more swipe direction options, a total of 8. This means that the user can start from the car screen with the first level of permissions and swipe in 8 different directions to select other car screens to link with it. The car screens with other permissions have fewer swipe direction options, with 3 to 5. These screens have more specific roles or functions in the system, so they do not need too many linkage direction options.

[0063] During operation, on the activated car screen, the user selects a suitable swiping direction according to the target car screen that he wants to link. Then a linkage request is initiated, and the user swipes along the selected swiping direction. After the linkage selection module recognizes this operation, it immediately initiates a linkage request to the other car screen pointed to by the swiping direction with the car screen as the origin. Then a linkage relationship is established: after the car screen requested to link receives the request, if it agrees to the linkage, it establishes a linkage relationship with the car screen that initiated the request and starts to execute the linkage operation.

[0064] In the embodiment of the present invention, the linked screen is selected by swiping operation, so that the user can flexibly adjust the linkage relationship as needed, which can improve the flexibility of operation. Screens with different permissions have different numbers of swiping direction options, which not only meets the needs of system functions, but also provides a personalized user experience, which can enhance the user experience. For screens with lower permissions or specific functions, reducing the swiping direction selection can save system resources, optimize system resources, and help improve the overall performance of the system.

[0065] The vehicle-mounted multi-screen linkage system of the embodiment of the present invention further includes a multi-screen selection module, which is configured to control multiple vehicle-mounted screens to be linked and can select a linkage mode.

[0066] In an embodiment of the present invention, the linkage mode includes a synchronous linkage mode and a cross-linkage mode. In the synchronous linkage mode, multiple vehicle-mounted screens will display the same content or perform the same operation at the same time. For example, when the driver chooses to play music on the main screen, other vehicle-mounted screens will also play the same music synchronously. In the cross-linkage mode, the user can specify one or more vehicle-mounted screens as linkage intermediaries to indirectly link with other vehicle-mounted screens through them. For example, the driver can select a navigation destination on the main screen, and then the information is passed to the vehicle-mounted screen in the back row through another vehicle-mounted screen (such as the co-pilot screen) so that passengers can understand the itinerary information.

[0067] By setting up the multi-screen selection module: when the user needs to link multiple car screens, or when multiple car screens are linked, you need to skip one of the car screens (when multiple car screens are linked, you do not want to link with one of the car screens), you can determine whether to use the synchronous linkage mode or the skip linkage mode through custom settings.

[0068] When the first car screen is linked through the multi-screen selection module, if the linkage operation is not completed, the first car screen can be used as the new origin of the next linkage operation, and then the linkage selection module can be used to swipe in a new direction to select the next car screen to be linked.

[0069] In the embodiment of the present invention, by setting a multi-screen selection module, the user is allowed to select different linkage modes as needed, thereby improving the operational flexibility of the system. By providing multiple linkage modes, the system can meet the needs and preferences of different users, thereby enhancing the user experience. The cross-linking mode allows the user to indirectly link with other screens by specifying an intermediary screen, which helps to optimize the path and efficiency of information transmission.

[0070] like Figure 5 As shown, through the screen activation module (such as long pressing anywhere on the screen with multiple fingers, the screen shrinking is activation), in theory each car screen has eight directions of swiping freedom (up, down, left, right, upper right, lower right, lower left, upper left), and if there is a corresponding object screen in the swiping direction, the screen linkage request can be completed. Each screen can be set to retain a part of the swiping freedom according to the actual position.

[0071] like Figure 6 As shown, there are 4 in-vehicle screens, namely the main screen, the first sub-screen, the second sub-screen and the third sub-screen. The first sub-screen is the co-driver sub-screen, the second sub-screen is the rear left sub-screen (located behind the main driver's seat), and the third sub-screen is the rear right sub-screen (located behind the co-driver's seat). The swiping direction of the main screen is set to right, down, and lower right, the swiping direction of the first sub-screen is set to left, down, and lower left, the swiping freedom of the second sub-screen is set to up, right, and upper right, and the swiping direction of the third sub-screen is set to up, left, and upper left.

[0072] like Figure 7As shown, there are 6 in-vehicle screens, which are the main screen, the first sub-screen, the second sub-screen, the third sub-screen, the fourth sub-screen and the fifth sub-screen. The first sub-screen is the co-driver sub-screen, the second sub-screen is the middle left sub-screen (located behind the main driver's seat), the third sub-screen is the middle right sub-screen (located behind the co-driver's seat), the fourth sub-screen is the rear left sub-screen (located behind the middle left sub-screen), and the fifth sub-screen is the rear right sub-screen (located behind the middle right sub-screen). The swiping direction of the main screen is set to right, down, and lower right, the swiping direction of the first sub-screen is set to left, down, and lower left, the swiping direction of the second sub-screen is set to up, down, right, upper right, and lower right, the swiping direction of the third sub-screen is set to up, down, left, upper left, and lower left, the swiping direction of the fourth sub-screen is set to up, right, and upper right, and the swiping direction of the fifth sub-screen is set to up, left, and upper left.

[0073] like Figure 8 and Fig. 9 As shown, among the 6 screens, how to link multiple screens (≥2 screens) together, this embodiment links the main screen to the third sub-screen, the fourth sub-screen, and the fifth sub-screen. Taking the linkage of the main screen, the third sub-screen, the fifth sub-screen, and the fourth sub-screen as an example, (long press with multiple fingers) activates the main screen to enter the waiting linkage state (screen reduction), and takes point A on the main screen as the action starting point, slides to the lower right to point B on the main screen, and the position of point B corresponds to the third sub-screen (the operations that can be selected at this time are: Operation 1: The swiping technique is an arc route. This swiping technique represents bypassing the third sub-screen. The third sub-screen is used as a springboard, and the main screen is not linked to the third sub-screen; Operation 2, the swiping technique is a straight line route. This swiping technique represents the linkage between the main screen and the third sub-screen, and the third sub-screen is used as a springboard and linked to the third sub-screen), and continues to slide downward from point B. Move to point C on the main screen, and point C corresponds to the fifth sub-screen (the operations you can choose at this time are: Operation 1: the swiping method is an arc route, which means bypassing the fifth sub-screen. The fifth sub-screen serves as a springboard, and the main screen is not linked to the fifth sub-screen; Operation 2: the swiping method is a straight line route, and this swiping method means that the main screen is linked to the fifth sub-screen. The fifth sub-screen serves as a springboard and is also linked to the fifth sub-screen), and continue to slide from point C to the left to point D on the main screen, and point D corresponds to the fourth sub-screen (there is no subsequent action after operating to the fourth sub-screen. For example, the user's finger leaves, it means that the multi-screen linkage input is ended, and the main screen is linked to the fourth sub-screen). As above, through the different choices of arc routes or straight line routes for the corresponding points of each screen, the screen can be accurately selected without wrong selection.

[0074] In the embodiment of the present invention, the screen in the cockpit is identified, and within the interconnection authority, the in-vehicle screen is added or deleted, and personalized operations can be performed as needed;

[0075] Through the design of different permission levels, the permission level of the screen can be adjusted according to actual needs and the identity of the passengers in front of each screen, so that the interconnection between screens can better meet the needs;

[0076] Each permission level has three permission areas: upper, middle and lower, which correspond to direct linkage, inquiry linkage and rejection linkage, respectively, to meet the needs of the user's current status and be more humane;

[0077] The interconnection is achieved by swiping, with straight lines and arcs corresponding to interconnection and non-interconnection. In a multi-screen vehicle, you can freely choose the interconnection between different screens, and this method can effectively avoid the wrong connection of screens when swiping in a multi-screen environment.

[0078] In a second aspect, the present invention further provides a method for using the vehicle-mounted multi-screen linkage system, comprising:

[0079] The permission setting module sets the permission level of the vehicle screen;

[0080] In the car screen, there are 8 swipe directions for the car screen with the first level of authority, and 3 to 5 swipe directions for the car screen with other authorities;

[0081] Among the vehicle screens, when one of the vehicle screens is activated and is in a link request state, swiping along the selected swiping direction on the vehicle screen will link to the other vehicle screen pointed to by the swiping direction, with the vehicle screen as the origin.

[0082] In a third aspect, the present invention also provides a vehicle, including the vehicle-mounted multi-screen linkage system of the above structure. The specific structure and use method of the vehicle-mounted multi-screen linkage system can be referred to Figures 1 to 11 Since the vehicle of the present invention includes the vehicle-mounted multi-screen linkage system in the above embodiment, it has all the advantages of the above vehicle-mounted multi-screen linkage system.

[0083] Embodiment 1

[0084] Permission level settings:

[0085] like Figure 1 and Figure 2 As shown, in the initial state, only the main screen (corresponding to the sequence number 1 in the figure) can set the permission level. The plus sign (+) below the first level permission can be used to add a second level permission level (the second level permission is lower than the first level permission level);

[0086] Similarly, you can add a lower permission level by clicking the + sign below the current lowest permission level (the permission levels are in descending order: first permission level > second permission level > third permission level > ... > Nth permission level). You can also delete a permission level by clicking the minus sign (-) on the right side of each permission level (except the first permission level).

[0087] The car system detects the car screen that is linked to itself. In the initial state, the screen that comes with the car system will be displayed on the right side of the setting interface and calibrated with a serial number. Users can customize the car screen corresponding to each serial number. As more and more car screens are connected to the car system, users can add serial numbers through the plus sign (+) below the screen serial number to facilitate the corresponding car screen. The number of newly added serial numbers is limited, and the maximum value of the car screen serial number is the total number of screens in the car system. For car screens with serial numbers, when the user does not want the car screen to be in the sequence, the serial number corresponding to the car screen can be deleted.

[0088] The car screen serial number can be pulled into the corresponding authority level and authority area (three attitude areas: upper area, middle area and lower area).

[0089] The first level of permission is the highest level of permission. Initially, only the main screen has this permission. When the main screen drags the first and seventh sub-screens into the first level of permission, the first and seventh sub-screens can exercise the same operating permissions as the main screen (except that they cannot change any settings of the main screen);

[0090] A high-authority vehicle screen can force linkage with other relatively low-authority object screens without the consent of the low-authority object screens, such as Figure 2 As shown, the first secondary screen can be forced to link with the second secondary screen, the seventh secondary screen, and the fifth secondary screen, and the second secondary screen can be forced to link with the fifth secondary screen;

[0091] When facing an object screen at the same or relatively higher authority level, a free linkage method is adopted, that is, it depends on which of the three attitude areas, the upper area, the middle area and the lower area, the object screen to be linked is located. If it is in the upper area, it means that the object screen can be linked directly without asking; if it is in the middle area, it means that the user of the object screen needs to be asked, and the linkage can be allowed if the user agrees, otherwise the linkage will be rejected; if it is in the lower area, it means that the user of the object screen rejects the linkage requests sent by other screens.

[0092] like Figure 3 As shown, each level of authority is divided into upper zone, middle zone and lower zone (upper zone = direct linkage, middle zone = inquiry linkage, lower zone = rejection linkage).

[0093] like Figure 2As mentioned above, the main screen is located in the upper area of ​​the first level of authority. As an object screen, the main screen can be directly linked to any other screen;

[0094] The first sub-screen is located in the middle area of ​​the first level of authority. As the target screen, the first sub-screen can be asked for linkage by any other screen. If the first sub-screen agrees, the linkage is established. If the first sub-screen disagrees, the linkage is rejected. Because the first sub-screen is at the first level of authority (the highest authority), no screen with a higher authority level can force linkage with the first sub-screen.

[0095] The seventh sub-screen is located in the lower area of ​​the first level of authority. The seventh sub-screen rejects linkage requests from any screen because the seventh sub-screen is located in the first level of authority (the highest authority), and no screen with a higher authority level can force linkage with the first sub-screen;

[0096] The third sub-screen is located in the upper area of ​​the second level of authority. As an object screen, the third sub-screen can be directly linked to any other screen;

[0097] The second sub-screen is located in the middle area of ​​the second level of authority. As the target screen, the second sub-screen can be asked for linkage by any other screen. If the second sub-screen agrees, the linkage is established. If the second sub-screen disagrees, the linkage is rejected. However, the second sub-screen cannot refuse the forced linkage of the main, first, and seventh sub-screens.

[0098] The seventh sub-screen is located in the lower area of ​​the second level of authority. The seventh sub-screen indicates that it will reject linkage requests from any screen, but the seventh sub-screen cannot reject forced linkage from the main first sub-screen and the sixth sub-screen.

[0099] Summary: 1. The main screen has the highest level of permissions, and the permissions cannot be changed by other secondary screens;

[0100] 2. Screens with high-level permissions have the right to force linkage with screens with low-level permissions;

[0101] 3. The screen within the first level of authority has the authority to operate other secondary screens, that is, the secondary screen within the first level of authority is the screen that is granted the same authority by the main screen, and can exercise all the rights of the main screen over other secondary screens (except for changing the authority of the main screen, and the authority of the main screen is higher than that of any secondary screen, that is, the rights of the first level of authority can be granted to a secondary screen and the rights of the secondary screen can be deprived at any time);

[0102] 4. The screen adopts free linkage between the same level permissions and between low-level permissions and high-level permissions;

[0103] 5. The car-connected screen detected in the car system can be matched with the screen number in the permission setting interface through the screen setting module. By pulling the screen number into a certain level of permission and the permission area, the screen permission can be set and adjusted.

[0104] Embodiment 2

[0105] Transfer and lock of permission levels and permission areas:

[0106] In the permission setting interface, drag the serial number corresponding to each screen into the permission area within the corresponding permission level to complete the transfer of screen permissions.

[0107] like Figure 4 As shown in the figure, there is a lock icon on the left side of each permission level. If the lock icon on the left side of the permission level is unlocked, Figure 4 The second level of permissions in the second level, the lock icon on the left is unlocked, then the second, third, and seventh sub-screens are within the second level of permissions. These three sub-screens can customize the permission area of ​​their own screen numbers in the second level of permissions, corresponding to Figure 2 and Figure 4 In the unlocked state, the seventh sub-screen located in the lower area of ​​the second level authority can be transferred to the upper area; Figure 4 If the third-level permission is selected and the lock icon on the left is in locked state, then the fourth and fifth sub-screens are within the third-level permission, and the two screens cannot customize the permission area of ​​their own screen numbers in the third-level permission.

[0108] Summary: 1. Only the first-level permission screen has the authority to adjust the permission settings of other secondary screens;

[0109] 2. Within each unlocked level of permission, the screen can customize the permission area within that level of permission. Within each locked level of permission, the screen cannot transfer and select the permission area.

[0110] Embodiment 3

[0111] How to select the linkage of the screen:

[0112] like Figure 5 As shown, through the screen activation module (such as long pressing anywhere on the screen with multiple fingers, the screen shrinking is activation), in theory each car screen has eight directions of swiping freedom (up, down, left, right, upper right, lower right, lower left, upper left), and if there is a corresponding object screen in the swiping direction, the screen linkage request can be completed. Each screen can be set to retain a part of the swiping freedom according to the actual position.

[0113] like Figure 6As shown, there are 4 in-vehicle screens, namely the main screen, the first sub-screen, the second sub-screen and the third sub-screen. The first sub-screen is the co-driver sub-screen, the second sub-screen is the rear left sub-screen (located behind the main driver's seat), and the third sub-screen is the rear right sub-screen (located behind the co-driver's seat). The swiping direction of the main screen is set to right, down, and lower right, the swiping direction of the first sub-screen is set to left, down, and lower left, the swiping freedom of the second sub-screen is set to up, right, and upper right, and the swiping direction of the third sub-screen is set to up, left, and upper left.

[0114] like Figure 7 As shown, there are 6 in-vehicle screens, which are the main screen, the first sub-screen, the second sub-screen, the third sub-screen, the fourth sub-screen and the fifth sub-screen. The first sub-screen is the co-driver sub-screen, the second sub-screen is the center-left sub-screen (located behind the main driver's seat), the third sub-screen is the center-right sub-screen (located behind the co-driver's seat), the fourth sub-screen is the rear left sub-screen (located behind the center-left sub-screen), and the fifth sub-screen is the rear right sub-screen (located behind the center-right sub-screen). The swiping direction of the main screen is set to right, down, and lower right, the swiping direction of the first sub-screen is set to left, down, and lower left, the swiping direction of the second sub-screen is set to up, down, right, upper right, and lower right, the swiping direction of the third sub-screen is set to up, down, left, upper left, and lower left, the swiping direction of the fourth sub-screen is set to up, right, and upper right, and the swiping direction of the fifth sub-screen is set to up, left, and upper left.

[0115] like Figure 8 and Fig. 9As shown, among the 6 screens, how to link multiple screens (≥2 screens) together, this embodiment links the main screen to the third sub-screen, the fourth sub-screen, and the fifth sub-screen. Taking the linkage of the main screen, the third sub-screen, the fifth sub-screen, and the fourth sub-screen as an example, (long press with multiple fingers) activates the main screen to enter the waiting linkage state (screen reduction), and takes point A on the main screen as the action starting point, slides to the lower right to point B on the main screen, and the position of point B corresponds to the third sub-screen (the operations that can be selected at this time are: Operation 1: The swiping technique is an arc route. This swiping technique represents bypassing the third sub-screen. The third sub-screen is used as a springboard, and the main screen is not linked to the third sub-screen; Operation 2, the swiping technique is a straight line route. This swiping technique represents the linkage between the main screen and the third sub-screen, and the third sub-screen is used as a springboard and linked to the third sub-screen), and continues to slide downward from point B. Move to point C on the main screen, and point C corresponds to the fifth sub-screen (the operations you can choose at this time are: Operation 1: the swiping method is an arc route, which means bypassing the fifth sub-screen. The fifth sub-screen serves as a springboard, and the main screen is not linked to the fifth sub-screen; Operation 2: the swiping method is a straight line route, and this swiping method means that the main screen is linked to the fifth sub-screen. The fifth sub-screen serves as a springboard and is also linked to the fifth sub-screen), and continue to slide from point C to the left to point D on the main screen, and point D corresponds to the fourth sub-screen (there is no subsequent action after operating to the fourth sub-screen. For example, the user's finger leaves, it means that the multi-screen linkage input is ended, and the main screen is linked to the fourth sub-screen). As above, through the different choices of arc routes or straight line routes for the corresponding points of each screen, the screen can be accurately selected without wrong selection.

[0117] The secondary screen sends a linkage to the primary screen.

[0118] Usage scenario: The driver is driving a vehicle on a complex road and needs to perform navigation operations without being distracted. At this time, the driver can perform navigation operations on his own screen through other secondary screens, and then link his own screen to the main screen, so that the driver can get the navigation interface without being distracted.

[0119] How to do it:

[0120] The first step is to set permissions and linkage methods. If the main screen is located in the upper or middle area of ​​the first level of permissions, the linkage with other screens is open and can be linked with other secondary screens directly or after asking. If the main screen is located in the lower area of ​​the first level of permissions, it means that the main screen is in a rejected state for any linkage with other screens.

[0121] The second step is the link operation. Other secondary screens perform navigation operations on their own screens. After starting the navigation interface, the interface on their own secondary screens is linked to the main screen through the link operation module. In this way, the navigation interface on the secondary screen can be directly displayed on the main screen.

[0122] With this operation, when the driver needs to control and adjust the main screen interface, he can use the assistance of other sub-screens. It is not necessary for there to be someone on the passenger seat. Passengers in any position, as long as there is a screen connected to the car computer in front of them, can operate the interface content through the screen, and then directly link the screen content to the main screen, making driving safer for the driver.

[0123] Embodiment 5

[0124] There are two situations when the main screen sends a linkage to the secondary screen, as described below.

[0125] The first type is that the permission level of the main screen is higher than that of the secondary screen. No matter where the secondary screen is located, the main screen can forcibly link with the secondary screen without the consent of the secondary screen.

[0126] The second type is that the authority level of the main screen is the same as that of the sub-screen. When the sub-screen is in the upper area, the main screen can directly link with the sub-screen without asking. When the sub-screen is in the middle area, the main screen needs to ask the sub-screen's willingness when issuing a linkage request. If the sub-screen chooses to agree, the main screen can smoothly link with the sub-screen. If the sub-screen chooses to refuse, the main screen cannot link with the sub-screen. When the sub-screen is in the lower area, the main screen will be directly rejected by the sub-screen when issuing a linkage request, and cannot link with the sub-screen.

[0127] Embodiment 6

[0128] There are two situations when the secondary screen sends a linkage to the secondary screen, which are explained as follows.

[0129] The first type is that the permission level of the first secondary screen is higher than that of the second secondary screen. No matter where the second secondary screen is located, the first secondary screen can be forced to link with the second secondary screen without the consent of the second secondary screen.

[0130] The second type is that the authority level of the first sub-screen is the same as that of the second sub-screen. When the second sub-screen is in the upper area, the first sub-screen can directly link with the second sub-screen without asking. When the second sub-screen is in the middle area, when the first sub-screen sends a linkage request, it is necessary to ask the second sub-screen about its willingness. If the second sub-screen chooses to agree, the first sub-screen can smoothly link with the second sub-screen. If the second sub-screen chooses to refuse, the first sub-screen cannot link with the second sub-screen. When the second sub-screen is in the lower area, when the first sub-screen sends a linkage request, it will be directly rejected by the second sub-screen and cannot link with the second sub-screen.

[0131] Embodiment 7

[0132] like Fig.10 and Fig.11 As shown, a method for determining whether the in-vehicle screens can be successfully linked.

[0133] The first step is to identify the activated vehicle screen, which includes the vehicle screen requesting linkage and the vehicle screen receiving linkage (activating the screen by finger touching the screen or activating the screen by voice interaction);

[0134] The second step is to determine the authority level. The on-board screen that requests linkage and the on-board screen that receives linkage are identified at their authority levels, and compared to determine whether their authority levels are high or low. There are three results for the comparison of authority levels of the on-board screen that requests linkage and the on-board screen that receives linkage (high: low, average: average, low: high).

[0135] The third step is to determine the permission area. The vehicle screen requesting linkage and the vehicle screen receiving linkage should identify the permission area positions of the two in their respective permission levels.

[0136] In the fourth step, according to the difference in permission level and permission area location between the vehicle screen requesting linkage and the vehicle screen receiving linkage, the processor determines whether the linkage between the vehicle screens is successful according to the set rules.

[0137] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
