TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent networked vehicles, and in particular relates to a steering wheel control signal distribution method and device based on a vehicle-mounted multi-screen system. BACKGROUND

[0002] With the rapid development of intelligent networked vehicles and intelligent cockpit technologies, more and more vehicle models are equipped with multi-screen collaborative display systems including instrument screens, central control main screens, co-pilot entertainment screens, HUD (Head-Up Display) display screens, rear entertainment screens, and the like. This multi-screen trend significantly improves the driving and riding experience.

[0003] In related technologies, physical buttons on the steering wheel (such as volume control, menu switching, multimedia control, etc.) are generally bound to the central control main screen or the instrument screen by default, that is, when a user operates a steering wheel button, the control signal can directly act on the corresponding fixed screen.

[0004] However, this method cannot flexibly adapt to multi-screen interaction scenarios when facing multi-screen collaborative display systems, and problems such as control signal response confusion and frequent control conflicts easily occur, which need to be solved urgently. SUMMARY

[0005] The present application provides a steering wheel control signal distribution method based on a vehicle-mounted multi-screen system to solve the problem that the steering wheel control signal in the traditional vehicle-mounted system cannot flexibly adapt to multi-screen interaction scenarios, and to realize intelligent identification, dynamic distribution, and conflict coordination of control signals, thereby improving multi-screen collaborative experience and interaction accuracy.

[0006] To achieve the above-mentioned purpose, the first aspect of the present application proposes a steering wheel control signal distribution method based on a vehicle-mounted multi-screen system, comprising the following steps: obtaining a current control signal of a steering wheel, and determining a current control signal content based on the current control signal; determining a target to-be-controlled screen based on the current control signal content and a dynamic multi-screen interaction focus table, wherein the dynamic multi-screen interaction focus table is dynamically generated based on real-time interaction states of multiple screens; sending the current control signal to the target to-be-controlled screen to perform a corresponding control operation on the target to-be-controlled screen based on the current control signal.

[0007] According to one embodiment of the present application, determining a target to-be-controlled screen based on the current control signal content and a dynamic multi-screen interaction focus table comprises: judging whether there are multiple candidate to-be-controlled screens based on the current control signal content and the dynamic multi-screen interaction focus table; If there are multiple candidate screens to be controlled, the target screen to be controlled is determined from the multiple candidate screens based on a preset conflict coordination strategy, wherein the preset conflict coordination strategy includes multiple decision factors; otherwise, the unique candidate screen to be controlled is taken as the target screen to be controlled.

[0008] According to one embodiment of this application, determining the target screen to be controlled from a plurality of candidate screens to be controlled based on a preset conflict coordination strategy includes: Based on the current interaction state of each candidate screen to be controlled and the preset scoring mechanism corresponding to each decision factor, calculate the decision factor score set for each candidate screen to be controlled. The decision factor scores of each candidate screen to be controlled are weighted and summed to obtain the comprehensive score of each candidate screen to be controlled. The target screen to be controlled is determined based on the comprehensive score of each candidate screen to be controlled.

[0009] According to one embodiment of this application, the dynamic multi-screen interactive focus table is dynamically generated based on the real-time interactive states of multiple screens, including: Obtain the active cutoff time and current time for each screen in the dynamic multi-screen interaction focus table; Determine whether the interval between the current time and the active cutoff time of each screen is greater than or equal to a preset duration; If the interval between the current time and the active cutoff time of any of the screens is greater than or equal to the preset duration, the screen with the interval greater than or equal to the preset duration is removed from the dynamic multi-screen interaction focus table.

[0010] According to one embodiment of this application, the decision factor is at least one of user role priority, task function urgency, interaction time sequence, and the degree of correlation between control signals and screen functions.

[0011] According to the steering wheel control signal distribution method for an in-vehicle multi-screen system proposed in this application, the current control signal of the steering wheel can be obtained, and the content of the current control signal can be determined based on the current control signal. Then, based on the content of the current control signal and the dynamic multi-screen interaction focus table, the target screen to be controlled is determined, and the current control signal is sent to the target screen to be controlled, so as to perform corresponding control operations on the target screen based on the current control signal. Thus, the precise distribution of control signals is achieved through the dynamic multi-screen interaction focus table, which solves the problem that steering wheel control signals in traditional in-vehicle systems cannot flexibly adapt to multi-screen interaction scenarios, realizes intelligent recognition, dynamic distribution and conflict coordination of control signals, and improves the multi-screen collaborative experience and interaction accuracy.

[0012] To achieve the above objectives, a second aspect of this application provides a steering wheel control signal distribution device based on an in-vehicle multi-screen system, comprising: The first determining module is used to acquire the current control signal of the steering wheel and determine the content of the current control signal based on the current control signal; The second determining module is used to determine the target screen to be controlled based on the current control signal content and the dynamic multi-screen interaction focus table, wherein the dynamic multi-screen interaction focus table is dynamically generated based on the real-time interaction status of multiple screens. The control module is used to send the current control signal to the target screen to be controlled, so as to perform corresponding control operations on the target screen to be controlled based on the current control signal.

[0013] According to one embodiment of this application, the second determining module includes: The judgment unit is used to determine whether there are multiple candidate screens to be controlled based on the current control signal content and the dynamic multi-screen interaction focus table; The determining unit is configured to determine the target screen to be controlled from the multiple candidate screens to be controlled based on a preset conflict coordination strategy when multiple candidate screens to be controlled exist. The preset conflict coordination strategy includes multiple decision factors. Otherwise, the unique candidate screen to be controlled is taken as the target screen to be controlled.

[0014] According to one embodiment of this application, the determining unit is specifically used for: Based on the current interaction state of each candidate screen to be controlled and the preset scoring mechanism corresponding to each decision factor, calculate the decision factor score set for each candidate screen to be controlled. The decision factor scores of each candidate screen to be controlled are weighted and summed to obtain the comprehensive score of each candidate screen to be controlled. The target screen to be controlled is determined based on the comprehensive score of each candidate screen to be controlled.

[0015] According to one embodiment of this application, the second determining module is specifically used for: Obtain the active cutoff time and current time for each screen in the dynamic multi-screen interaction focus table; Determine whether the interval between the current time and the active cutoff time of each screen is greater than or equal to a preset duration; If the interval between the current time and the active cutoff time of any of the screens is greater than or equal to the preset duration, the screen with the interval greater than or equal to the preset duration is removed from the dynamic multi-screen interaction focus table.

[0016] According to one embodiment of this application, the decision factor is at least one of user role priority, task function urgency, interaction time sequence, and the degree of correlation between control signals and screen functions.

[0017] According to the steering wheel control signal distribution device based on an in-vehicle multi-screen system proposed in this application, by acquiring the current control signal of the steering wheel, the content of the current control signal can be determined based on the current control signal; then, based on the current control signal content and a dynamic multi-screen interaction focus table, the target screen to be controlled is determined, and the current control signal is sent to the target screen to be controlled, so as to perform corresponding control operations on the target screen based on the current control signal. Thus, the precise distribution of control signals is achieved through the dynamic multi-screen interaction focus table, solving the problem that steering wheel control signals in traditional in-vehicle systems cannot flexibly adapt to multi-screen interaction scenarios, realizing intelligent recognition, dynamic distribution, and conflict coordination of control signals, and improving the multi-screen collaborative experience and interaction accuracy.

[0018] To achieve the above objectives, a third aspect of this application provides a vehicle comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steering wheel control signal distribution method based on an in-vehicle multi-screen system as described in the above embodiments.

Figure 2 This is a block diagram of a steering wheel control signal distribution device based on an in-vehicle multi-screen system according to an embodiment of this application; Figure 3 This is a structural schematic diagram of a vehicle provided according to an embodiment of this application. Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0023] The method and apparatus for distributing steering wheel control signals based on an in-vehicle multi-screen system according to embodiments of this application will now be described with reference to the accompanying drawings. First, the method for distributing steering wheel control signals based on an in-vehicle multi-screen system according to embodiments of this application will be described with reference to the accompanying drawings.

[0024] Figure 1 This is a flowchart of a steering wheel control signal distribution method based on an in-vehicle multi-screen system according to an embodiment of this application.

[0025] For example, such as Figure 1 As shown, the steering wheel control signal distribution method based on the in-vehicle multi-screen system includes the following steps: In step S101, the current control signal of the steering wheel is obtained, and the content of the current control signal is determined based on the current control signal.

[0026] Specifically, when the driver operates any function button on the steering wheel (e.g., volume up / down, menu switching, confirmation / cancel, multimedia playback control, etc.), a corresponding control signal is generated. This control signal can be uploaded to the intelligent cockpit control system in real time via the CAN (Controller Area Network) bus or other in-vehicle communication protocols (such as LIN (Local Interconnect Network) bus, in-vehicle Ethernet, etc.). After receiving the signal, the intelligent cockpit control system can accurately identify the content of the triggered control signal. The control signal content can include the control signal type, the specific button triggered, and its corresponding instruction. The intelligent cockpit control system can also automatically record detailed information and a precise trigger timestamp of the control signal for subsequent data analysis or functional response. Control signal types can be categorized as functional (referring to control the vehicle's core functions, system settings, or safety-related functions, such as voice assistant activation, driving mode selection, cruise control, etc.), navigation (referring to interaction with the in-vehicle navigation system, controlling map display and route guidance), or media (referring to control the audio and video playback sources and related settings of the in-vehicle infotainment system). In addition, the intelligent cockpit control system can determine the responsiveness of the current screen based on the current control signal, that is, determine whether the command is effective for the target screen to be controlled, thereby achieving precise screen control.

[0027] In step S102, the target screen to be controlled is determined based on the current control signal content and the dynamic multi-screen interaction focus table, wherein the dynamic multi-screen interaction focus table is dynamically generated based on the real-time interaction status of multiple screens.

[0028] Specifically, after obtaining the content of the current control signal triggered by the steering wheel (i.e., the current control signal content), based on the current control signal content and by querying the dynamic multi-screen interaction focus table, the screen currently in the main interaction state can be identified as the target screen to be controlled.

[0029] It's important to note that the dynamic multi-screen interaction focus table isn't pre-configured statically; rather, it acts like a real-time updated "battle map," reflecting the real-time interaction activity of all screens in the vehicle. The intelligent cockpit control system continuously monitors the status information of each in-vehicle display screen (including whether a screen is currently in touch mode; for example, if the passenger touches the entertainment screen, the screen's status in the table is immediately updated to "active," marked as "touch"; whether a voice command has been issued to a specific screen; for example, if the driver says "turn on the air conditioning," the air conditioning interface pops up on the central control screen, and the central control screen's status is updated to "active," marked as "voice command"; whether the currently active task is bound to a specific display screen; whether there is someone in the passenger seat or rear seats (which can be determined through cameras, pressure sensors, etc.); and whether the screen interface is in "active," "full-screen," or "main operation" states). By integrating the status information of each in-vehicle display screen, a real-time dynamic multi-screen interaction focus table can be established.

[0030] Each record in this table can contain the following information: screen ID, such as "central control screen", "passenger entertainment screen", "instrument screen", etc.; interaction status, such as "active", "inactive", "focused"; active context, i.e. what caused it to be active (e.g., "recent touch", "voice command pointing", "foreground navigation task", "playing video in full screen", etc.); associated user, i.e. the main user currently interacting with this screen (driver, passenger, rear seat); timestamp, i.e. the time when the last active event occurred.

[0031] For example, if the current control signal is "next track", the intelligent cockpit control system can select the screen currently running a media playback application (such as the music app on the central control screen or the video app on the passenger screen) as the target screen to be controlled.

[0032] To facilitate understanding, the following details how to determine the target screen to be controlled based on the current control signal content and the dynamic multi-screen interaction focus table.

[0033] As one possible implementation, in some embodiments, determining the target screen to be controlled based on the current control signal content and the dynamic multi-screen interaction focus table includes: determining whether there are multiple candidate screens to be controlled based on the current control signal content and the dynamic multi-screen interaction focus table; if there are multiple candidate screens to be controlled, determining the target screen to be controlled from the multiple candidate screens to be controlled based on a preset conflict coordination strategy, wherein the preset conflict coordination strategy includes multiple decision factors; otherwise, the only candidate screen to be controlled is taken as the target screen to be controlled.

[0034] Specifically, the intelligent cockpit control system first matches the current control signal content with the current status and capabilities of each active screen in the dynamic multi-screen interaction focus table. For example, when the driver presses the "next track" button, by querying the dynamic multi-screen interaction focus table, it finds that both the central control screen (playing music in the background) and the passenger entertainment screen (playing video in the foreground) are active and have media playback functions. At this time, the system determines that there are multiple candidate screens to be controlled. When the driver presses the "instrument panel menu switch" button, by querying the dynamic multi-screen interaction focus table, it finds that only the instrument panel has the function to respond to this special command. At this time, the system determines that there is a unique candidate screen to be controlled.

[0035] If the determination result is that there are multiple candidate screens to be controlled, an intelligent arbitration mechanism (i.e., a preset conflict coordination strategy) can be activated to output a unique target screen to be controlled from the multiple candidate screens; if the determination result is that there is a unique candidate screen to be controlled, then the unique candidate screen to be controlled can be used as the target screen to be controlled.

[0036] In some embodiments, the decision factors are at least one of the following: user role priority, task urgency, interaction sequence, and the degree of association between control signals and screen functions.

[0037] It is understandable that the pre-defined conflict coordination strategy is not a single rule, but an evaluation system composed of multiple decision factors. These decision factors include, but are not limited to, user role priority, task urgency, interaction sequence, and the correlation between control signals and screen functions. User role priority refers to assigning different levels of control authority to users in different seats, typically driver > front passenger > rear passenger; task urgency refers to the urgency or safety level of different in-vehicle functions, such as: navigation warning / collision warning (safety alert) > incoming call > navigation > media playback / settings; interaction sequence refers to the intuitive logic that "the last interactor has temporary control," that is, assigning higher weight to the most recently occurring interaction; the correlation between control signals and screen functions refers to the degree of matching between control signals and the current function of the candidate screen—the higher the matching degree, the more intuitive the user experience.

[0038] As one possible implementation, in some embodiments, the target screen to be controlled is determined from multiple candidate screens to be controlled based on a preset conflict coordination strategy, including: calculating the decision factor score set of each candidate screen to be controlled according to the current interaction state of each candidate screen to be controlled and the preset scoring mechanism corresponding to each decision factor; weighting and summing the decision factor score sets of each candidate screen to be controlled to obtain a comprehensive score value for each candidate screen to be controlled; and determining the target screen to be controlled based on the comprehensive score value of each candidate screen to be controlled.

[0039] Specifically, the intelligent cockpit control system can identify multiple candidate screens to be controlled as independent candidates for evaluation. Different decision factors have varying degrees of influence on the final control objective, and the system can assign a corresponding weight coefficient to each decision factor to reflect its importance in the overall decision-making process. For each candidate screen to be controlled, the scores of each decision factor are multiplied by their corresponding weights, and then summed to obtain a comprehensive score. The candidate screen with the highest comprehensive score is then determined as the target screen to be controlled.

[0040] For example, the weight corresponding to user role priority is 0.5, the weight corresponding to task urgency is 0.3, and the weight corresponding to the correlation between control signals and screen functions is 0.2 (for simplicity, this example does not consider the "order of interaction time"). The preset scoring mechanism (out of 10) for user role priority is: screens associated with the driver -10 points; screens associated with the front passenger -5 points; screens associated with the back seat -2 points. The preset scoring mechanism (out of 10) for task urgency is: safety alarms, incoming calls -10 points; navigation -7 points; media playback, settings -3 points. The preset scoring mechanism (out of 10) for the correlation between control signals and screen functions is: "next track" signal and screen playing media: 10 points; "next track" signal and screen not playing media (such as navigation): 1 point.

[0041] Assuming candidate screen 1 is the central control screen (displaying navigation) and candidate screen 2 is the passenger entertainment screen (in the media application interface), the following scoring is based on the preset scoring mechanism and weights. For candidate screen 1, the central control screen (displaying navigation), its user role is associated with the driver, corresponding to 10 points; the urgency of the task function is associated with the navigation task, which is 7 points; and the correlation between the control signal and the screen function is: "Next track" is not related to the navigation interface, which is 1 point. Therefore, the comprehensive score of candidate screen 1 = (user role score × weight) + (task urgency score × weight) + (signal correlation score × weight) = (10 × 0.5) + (7 × 0.3) + (1 × 0.2) = 5 + 2.1 + 0.2 = 7.3.

[0042] For candidate screen 2, which is the passenger entertainment screen (located in the media application interface), its user role is associated with the passenger, corresponding to 5 points; the urgency of the task function is related to media playback, which is 3 points; and the correlation between the control signal and the screen function is highly correlated with media playback, which is 10 points. Therefore, the comprehensive score of candidate screen 2 = (user role score × weight) + (task urgency score × weight) + (signal correlation score × weight) = (5 × 0.5) + (3 × 0.3) + (10 × 0.2) = 2.5 + 0.9 + 2 = 5.4.

[0043] Therefore, the target screen to be controlled is the central control screen (displaying navigation).

[0044] It should be noted that in the following situations, such as when no screen in the dynamic multi-screen interaction focus table is marked as "active" (e.g., when the vehicle has just started and all screens are in standby or on the home screen, with no one operating them); or when some screens are active but their activity levels are very low and their priorities are difficult to distinguish (e.g., the central control screen and instrument panel are both on their default interfaces and have not been interacted with in the last minute); or when even if the preset conflict coordination strategy is enabled, it is impossible to filter out a single target screen to be controlled (i.e., the target screen to be controlled cannot be clearly identified), then the default priority rule can be used to select the target screen to be controlled. The default priority rule is a fixed sorting rule preset during the system design phase, such as instrument panel / HUD > central control screen > driver's side functions. The instrument panel / HUD are directly in front of the driver, displaying the most critical driving information (vehicle speed, warnings, navigation prompts). Giving them control by default ensures that the driver's line of sight remains on the road to the greatest extent possible, making it the safest choice. For example, if the target screen to be controlled is unclear, pressing the "page up / down" buttons on the steering wheel will default to operating the menu on the instrument cluster screen. The central control screen is the most crucial interactive interface in the vehicle, integrating most entertainment, navigation, and vehicle settings functions. It serves as the driver's second interaction option and is the central hub for all vehicle functions. For example, if the target screen to be controlled is unclear, pressing the "volume adjustment" or "media playback" button will default to controlling the media applications on the central control screen.

[0045] The following details how to obtain the dynamic multi-screen interaction focus table.

[0046] As one possible implementation, in some embodiments, the dynamic multi-screen interaction focus table is dynamically generated based on the real-time interaction status of multiple screens, including: obtaining the active expiration time and the current time of each screen in the dynamic multi-screen interaction focus table; determining whether the interval between the current time and the active expiration time of each screen is greater than or equal to a preset duration; if the interval between the current time and the active expiration time of any screen is greater than or equal to the preset duration, removing the screen with an interval duration greater than or equal to the preset duration from the dynamic multi-screen interaction focus table.

[0047] It is understandable that the active cutoff time refers to the moment when the interaction of each screen in the dynamic multi-screen interaction focus table stops, that is, the time point at which a screen changes from an active state to an inactive state.

[0048] Specifically, by calculating the interval between the current time and the active expiration time of each screen, and determining whether the interval corresponding to each screen is greater than or equal to the preset time (such as 10 seconds), if the interval corresponding to a certain screen is greater than or equal to the preset time, it can be said that the screen has been idle for a long enough time, and the system determines that the user is no longer interacting with it, and the screen can be removed from the dynamic multi-screen interaction focus table.

[0049] Therefore, by designing a dynamic multi-screen interaction focus table, it can be ensured that the table always reflects the active screens currently interacting with the user. This allows the system to more accurately distribute steering wheel control signals, sending control commands only to those screens that are still active, avoiding invalid signal transmission to inactive screens, thereby improving the overall interaction efficiency and response speed of the in-vehicle multi-screen system.

[0050] In step S103, a current control signal is sent to the target screen to be controlled, so as to perform corresponding control operations on the target screen to be controlled based on the current control signal.

[0051] Specifically, after identifying the target screen to be controlled, the current control signal can be routed to the target screen and the corresponding response module can be invoked for processing. For example, if the passenger screen is the current focus of interaction (i.e., the target screen to be controlled), then the steering wheel "confirm" button will directly act on the passenger screen; if the passenger screen is not interacting and the instrument panel is navigating, then the "menu" operation will default to acting on the instrument panel.

[0052] According to the steering wheel control signal distribution method for an in-vehicle multi-screen system proposed in this application, the current control signal of the steering wheel can be obtained, and the content of the current control signal can be determined based on the current control signal. Then, based on the content of the current control signal and the dynamic multi-screen interaction focus table, the target screen to be controlled is determined, and the current control signal is sent to the target screen to be controlled, so as to perform corresponding control operations on the target screen based on the current control signal. Thus, the precise distribution of control signals is achieved through the dynamic multi-screen interaction focus table, which solves the problem that steering wheel control signals in traditional in-vehicle systems cannot flexibly adapt to multi-screen interaction scenarios, realizes intelligent recognition, dynamic distribution and conflict coordination of control signals, and improves the multi-screen collaborative experience and interaction accuracy.

[0053] Next, referring to the accompanying drawings, a steering wheel control signal distribution device based on an in-vehicle multi-screen system according to an embodiment of this application is described.

[0054] Figure 2 This is a block diagram of a steering wheel control signal distribution device based on an in-vehicle multi-screen system according to an embodiment of this application.

[0055] like Figure 2 As shown, the steering wheel control signal distribution device 10 based on the in-vehicle multi-screen system includes: a first determining module 100, a second determining module 200, and a control module 300.

[0056] The first determining module 100 is used to acquire the current control signal of the steering wheel and determine the content of the current control signal based on the current control signal. The second determining module 200 is used to determine the target screen to be controlled based on the current control signal content and the dynamic multi-screen interaction focus table, wherein the dynamic multi-screen interaction focus table is dynamically generated based on the real-time interaction status of multiple screens. The control module 200 is used to send the current control signal to the target screen to be controlled, so as to perform corresponding control operations on the target screen to be controlled based on the current control signal.

[0057] Optionally, in some embodiments, the second determining module 200 includes: The judgment unit is used to determine whether there are multiple candidate screens to be controlled based on the current control signal content and the dynamic multi-screen interaction focus table; The determining unit is used to determine the target screen to be controlled from the multiple candidate screens to be controlled based on a preset conflict coordination strategy when there are multiple candidate screens to be controlled. The preset conflict coordination strategy includes multiple decision factors. Otherwise, the only candidate screen to be controlled is taken as the target screen to be controlled.

[0058] Optionally, in some embodiments, the determining unit is specifically used for: Based on the current interaction state of each candidate screen to be controlled and the preset scoring mechanism corresponding to each decision factor, calculate the decision factor score set for each candidate screen to be controlled. The decision factor scores of each candidate screen to be controlled are weighted and summed to obtain the comprehensive score of each candidate screen to be controlled. The target screen to be controlled is determined based on the comprehensive score of each candidate screen to be controlled.

[0059] Optionally, in some embodiments, the second determining module 200 is specifically used for: Get the active cutoff time and current time for each screen in the dynamic multi-screen interaction focus table; Determine whether the interval between the current time and the active expiration time of each screen is greater than or equal to the preset duration; If the interval between the current time and the active expiration time of any screen is greater than or equal to a preset duration, the screen with an interval greater than or equal to the preset duration will be removed from the dynamic multi-screen interaction focus list.

[0060] Optionally, in some embodiments, the decision factor is at least one of user role priority, task urgency, interaction sequence, and the degree of association between control signals and screen functions.

[0061] It should be noted that the foregoing explanation of the embodiment of the steering wheel control signal distribution method based on the in-vehicle multi-screen system also applies to the steering wheel control signal distribution device based on the in-vehicle multi-screen system in this embodiment, and will not be repeated here.

[0062] According to the steering wheel control signal distribution device based on an in-vehicle multi-screen system proposed in this application, by acquiring the current control signal of the steering wheel, the content of the current control signal can be determined based on the current control signal; then, based on the current control signal content and a dynamic multi-screen interaction focus table, the target screen to be controlled is determined, and the current control signal is sent to the target screen to be controlled, so as to perform corresponding control operations on the target screen based on the current control signal. Thus, the precise distribution of control signals is achieved through the dynamic multi-screen interaction focus table, solving the problem that steering wheel control signals in traditional in-vehicle systems cannot flexibly adapt to multi-screen interaction scenarios, realizing intelligent recognition, dynamic distribution, and conflict coordination of control signals, and improving the multi-screen collaborative experience and interaction accuracy.

[0065] Furthermore, the vehicle also includes: Communication interface 303 is used for communication between memory 301 and processor 302.

[0068] If the memory 301, processor 302, and communication interface 303 are implemented independently, then the communication interface 303, memory 301, and processor 302 can be interconnected via a bus to complete communication between them. The bus can be an ISA (Industry Standard Architecture) bus, a PCI (Peripheral Component Interconnect) bus, or an EISA (Extended Industry Standard Architecture) bus, etc. The bus can be divided into address bus, data bus, control bus, etc. For ease of representation, Figure 3 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0069] Optionally, in a specific implementation, if the memory 301, processor 302, and communication interface 303 are integrated on a single chip, then the memory 301, processor 302, and communication interface 303 can communicate with each other through an internal interface.

[0070] Processor 302 may be a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), or one or more integrated circuits configured to implement the embodiments of this application.
