[0002] With the rapid development of the automobile industry and the increasing demand of consumers for in-car entertainment experience, the ceiling-mounted TV has become an indispensable part of modern cars. It not only provides passengers with a wealth of entertainment content, such as watching movies, TV programs, listening to music, etc., but also creates a more comfortable and personalized riding environment through linkage control with other devices in the cabin.

[0003] However, there are many problems with the traditional car ceiling TV control system.

[0004] On the one hand, these systems can usually only realize basic functions such as simple switches, volume adjustment and channel switching, lack effective linkage with other equipment in the cabin (such as audio systems, lighting systems, seat adjustment systems, etc.), and cannot provide personalized viewing experience based on users' actual needs and preferences.

[0005] On the other hand, due to the lack of real-time status monitoring and abnormality detection mechanism, when the car ceiling TV or equipment in the cabin fails, it cannot be discovered and handled in time, causing inconvenience to the user's normal use.

[0006] In addition, with the diversification of user needs, the traditional preset viewing mode can no longer meet the personalized needs of all passengers. Users hope to be able to freely customize the viewing mode according to their preferences and needs, including adjusting the screen brightness, sound effects, seat angle, etc., to obtain the best viewing experience. However, the existing in-vehicle ceiling TV control system lacks such customization functions, or the customization process is cumbersome and complicated, making it difficult to achieve fast and convenient personalized settings.

[0052] Figure 2 It is a schematic diagram of a cockpit linkage control system of a vehicle-mounted ceiling-mounted television provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0053] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0054] like Figure 1 As shown, an embodiment of the present invention provides a cockpit linkage control method for a vehicle-mounted ceiling-mounted TV, the method comprising the following steps:

[0055] Step 11, receiving user control instructions, the control instructions include opening instructions, closing instructions, volume adjustment instructions, channel switching instructions and playback control instructions;

[0056] Step 12, parsing the control command, identifying the command type, extracting the parameters in the command, including the volume, channel number and playback content, and converting the command into a corresponding control signal according to a preset command operation mapping table;

[0057] Step 13, according to the control signal, sending a control signal instruction to the vehicle-mounted ceiling TV to perform corresponding operations, including turning on or off the TV screen, adjusting the volume, switching to a specified TV channel or streaming media content, and controlling the playback progress;

[0058] Step 14, synchronizing the executed corresponding operation to the control unit in the vehicle cockpit in real time, adjusting the status of the relevant equipment in the cockpit, so as to realize the linkage control with the vehicle ceiling TV;

[0059] Step 15, real-time monitoring of the status of the vehicle ceiling-mounted TV and the linkage control of related equipment in the cabin. If an abnormality or failure occurs, a warning message is issued, and based on the usage data, the linkage control rules are personalized to customize specific viewing modes, including theater mode and children's mode.

[0060] In the embodiment of the present invention, steps 11 to 13 enable the system to quickly receive and analyze the user's control instructions, and then accurately send corresponding control signals to the vehicle-mounted ceiling TV to perform the operations required by the user. This fast response mechanism improves the user's operating experience, allowing the user to smoothly control the vehicle-mounted ceiling TV and enjoy a seamless entertainment experience.

[0061] The real-time synchronization mechanism in step 14 ensures that the operation of the vehicle ceiling TV can be immediately reflected on other related devices in the vehicle cabin, such as the audio system, lighting system, etc. This linkage control not only enhances the overall coordination of the in-car entertainment system, but also creates a more immersive viewing environment for users, improving the experience of watching movies or listening to music.

[0062] The real-time monitoring function of step 15 enables the system to continuously track the status of the vehicle-mounted ceiling TV and the equipment in the cabin, and immediately issue a warning message once an abnormality or fault is detected. This not only helps to find and solve problems in a timely manner, but also improves the stability and reliability of the system, ensuring that the user's entertainment experience is not interrupted. Through the use of data analysis and personalized adjustment of linkage control rules in step 15, the system can automatically adjust the viewing mode, such as theater mode, children's mode, etc., according to the user's preferences and usage habits. This personalized customization service not only improves user satisfaction, but also demonstrates the high intelligence and flexibility of the system. The implementation of the linkage control method enables the resources of the in-car entertainment system to be more reasonably allocated and utilized. Through precise control and coordination, the system can avoid unnecessary energy consumption and waste, thereby improving overall efficiency and extending the service life of the equipment.

[0063] In a preferred embodiment of the present invention, the above step 11, receiving a user control instruction, the control instruction includes an opening instruction, a closing instruction, a volume adjustment instruction, a channel switching instruction and a playback control instruction, and may include:

[0064] In an embodiment of the present invention, multiple input monitoring interfaces are configured and started, and these interfaces can be physical buttons, touch screens, voice recognition systems, etc. Each interface continuously monitors the user's input signal and is ready to receive control instructions. When the user issues a control instruction through any interface, the corresponding monitoring interface will capture the signal. The signal can be an electrical signal, a digital signal or an analog signal, and the specific form depends on the type of input device. The captured signal is preliminarily processed, such as denoising, amplification, digitization, etc., to ensure the accuracy and readability of the signal. If the signal comes from a voice recognition system, voice-to-text processing is also required. According to the preset instruction format and protocol, the pre-processed signal is parsed to identify the type of instruction (such as opening, closing, volume adjustment, channel switching, playback control, etc.). This involves operations such as decoding the signal, matching keywords or pattern recognition. After identifying the instruction type, specific parameter information is further extracted from the signal, such as volume, channel number, playback content, etc. These parameters will be used for subsequent control operations. According to the preset instruction operation mapping table, the identified instruction type and parameters are mapped to control signals that the system can understand and execute. The mapping table is a predefined set of rules that specifies the specific control operations and control parameters corresponding to each instruction type.

[0065] The mapped control signal is sent to the control module of the car ceiling TV through an appropriate communication protocol (such as CAN bus, LIN bus, Wi-Fi, Bluetooth, etc.). The control signal should contain enough information so that the TV module can accurately perform the required operation. After receiving the control signal, the control module of the car ceiling TV performs the corresponding operation according to the instruction type and parameters in the signal, such as turning on or off the TV screen, adjusting the volume, switching to a specified TV channel or streaming content, controlling the playback progress, etc. During the operation, interaction with TV hardware (such as display, speakers, tuner, etc.) may be involved. After the operation is completed, the TV control module will send a feedback signal to the system, indicating that the operation has been successfully executed or encountered some error. The system can confirm the result of the operation based on this feedback signal and perform corresponding processing (such as displaying a success prompt, recording a log, handling errors, etc.).

[0066] In a preferred embodiment of the present invention, the above step 12, parsing the control instruction, identifying the instruction type, extracting parameters in the instruction, including volume, channel number and playback content, and converting the instruction into a corresponding control signal according to a preset instruction operation mapping table, may include:

[0067] Step 121, predefine command modes, each mode corresponds to a command type, including an on command, an off command, and a volume adjustment command

[0068] Step 122, traverse the command data, compare it with the predefined command mode, and identify the command type by checking the header mark of the command, including opening, closing and volume adjustment;

[0069] Step 123, according to the instruction mode corresponding to the instruction type, locate the position of the parameter in the instruction, and extract the corresponding value according to the predefined parameter format, including extracting the value of the volume size for the volume adjustment instruction; extracting the value of the channel number for the channel switching instruction;

[0070] Step 124 : The instruction operation mapping table matches the instruction type and the extracted corresponding value with the corresponding control signal to generate a control signal.

[0071] In the embodiment of the present invention, during the system initialization phase, a command pattern library is created, wherein each pattern corresponds to a specific command type, such as an on command, an off command, a volume adjustment command, a channel switching command, and a playback control command, etc. These patterns define key information such as the command header identifier, parameter location, parameter format, and command length. The command pattern library is stored in the memory in the form of a data structure (such as an array, a linked list, a hash table, etc.) for quick access and comparison.

[0072] Step 122, when receiving a control command sent by the user, the system first obtains the original data of the command. Then, it traverses the command data and compares it with each pattern in the predefined command pattern library. During the comparison process, the system mainly checks the header identifier of the command to determine which command type it belongs to. Once a matching command pattern is found, the type of command is determined (such as turn on, turn off, volume adjustment, etc.).

[0073] Step 123, based on the identified instruction type, the system locates the corresponding instruction mode. In the instruction mode, the location and format information of the parameter are searched. Based on this information, the corresponding parameter value, such as volume, channel number, etc., is extracted from the instruction data. During the extraction process, the system will perform data type conversion, verification, and other processing to ensure the accuracy and validity of the parameter value.

[0074] Step 124, maintain an instruction operation mapping table, which associates the instruction type and the extracted parameter value with the corresponding control signal. When the instruction type and parameter value are determined, the system searches the mapping table to find the corresponding control signal. If there are multiple matching items in the mapping table, the control signal is selected according to the preset priority rule. Finally, the control signal is generated and output.

[0075] Assume that the user sends a control instruction, and its original data is "0x02 0x10 0x05", where "0x02" is the header identifier, indicating that this is a volume adjustment instruction, and "0x10 0x05" is the parameter part, indicating the volume level. Traverse the instruction data, identify the header identifier "0x02", and determine that this is a volume adjustment instruction. According to the mode of the volume adjustment instruction, the system locates the parameter position and extracts the volume level "0x10 0x05" (assuming that the volume level here is 256+5=261). Look up the instruction operation mapping table, match the volume adjustment instruction and the volume level 261 to the corresponding control signal, and generate the signal.

[0076] By pre-defining the command mode and command operation mapping table, the system can quickly identify the command type, extract parameter values ​​and generate control signals, thereby improving the efficiency of command parsing. Since both the command mode and the mapping table can be expanded and modified as needed, the system can easily adapt to different types of control commands and new control requirements. Accurate command parsing and fast control signal generation allow users to control the car ceiling TV more smoothly, thereby improving the user's viewing experience. Through strict command comparison and parameter extraction processes, the system can effectively reduce control errors caused by command parsing errors and improve the stability and reliability of the system.

[0077] In a preferred embodiment of the present invention, the above step 13, according to the control signal, sends a control signal instruction to the vehicle-mounted ceiling TV to perform corresponding operations, including turning on or off the TV screen, adjusting the volume, switching to a specified TV channel or streaming media content, and controlling the playback progress, may include:

[0078] Step 131, initializing a school of fish, wherein each fish represents a control signal sending scheme, including different sending times, sending modes or signal encoding modes;

[0079] Step 132, defining an objective function to evaluate the effect of each sending scheme to obtain an evaluation result;

[0080] Step 133, based on the evaluation result, simulate the foraging behavior of the fish school, each fish swims in the control signal sending scheme space, and evaluates the pros and cons of the current position of each fish based on the objective function;

[0081] Step 134, through multiple iterations, the fish school keeps swimming and gathering, and when the preset number of iterations is reached, the final control signal sending scheme is determined according to the objective function value of the fish;

[0082] Step 135, according to the final control signal sending scheme, a control signal is sent to the vehicle-mounted ceiling-mounted TV to perform corresponding operations.

[0083] In the embodiment of the present invention, a fish school data structure is initialized to store and manage multiple control signal transmission schemes. Each transmission scheme is abstracted as a "fish" and given attributes such as initial transmission time, transmission mode (such as wireless, wired, etc.) and signal encoding mode. These attributes can be preset or randomly generated according to actual conditions to ensure the diversity of the fish school.

[0084] Step 132, define an objective function for evaluating the effect of each control signal transmission scheme. The objective function can comprehensively consider multiple factors, such as signal transmission speed, accuracy, stability, energy consumption, etc., and score each scheme or calculate its pros and cons based on these factors.

[0085] Step 133, simulating the foraging behavior of the school of fish, that is, each "fish" swims in the sending plan space of the control signal and tries to find a better sending plan. During the swimming process, each fish will evaluate the pros and cons of its current position according to the objective function and exchange information with other fish (such as sharing the optimal position information). By simulating the collective behavior of the school of fish, such as gathering, dispersing, following, etc., the sending plan is continuously optimized.

[0086] Step 134, after multiple iterations, the fish school will continue to swim and gather, forming some relatively stable "fish school centers". The system determines whether the iteration is completed based on the preset number of iterations. When the iteration is completed, the final "fish" is selected from the fish school according to the objective function value as the final control signal sending solution.

[0087] Step 135, according to the final control signal sending scheme, a control signal is sent to the vehicle-mounted ceiling TV. The control signal may include instructions such as turning on or off the TV screen, adjusting the volume, switching to a specified TV channel or streaming media content, and controlling the playback progress. After receiving the control signal, the vehicle-mounted ceiling TV performs corresponding operations to meet the needs of the user.

[0088] Suppose you need to send a volume control signal to a car ceiling TV. When initializing the fish school, the system generates multiple sending schemes, including different sending times, sending methods, and signal encoding methods. Then, the system defines an objective function to evaluate the transmission speed and accuracy of each scheme. Next, the system simulates the foraging behavior of the fish school, allowing each "fish" to swim in the sending scheme space and evaluate the pros and cons of its current position based on the objective function. After multiple iterations, the final value of the fish is used as the final control signal sending scheme. Finally, according to the scheme, a volume control signal is sent to the car ceiling TV, and the TV successfully performs the volume adjustment operation.

[0089] By simulating the foraging behavior of fish schools, the system can quickly find the final control signal sending plan, improving the efficiency of signal sending. The fish school algorithm can automatically adapt to different control signal sending scenarios and requirements, making the system more flexible and reliable. By evaluating the effects of different sending plans, the system can select the final plan for signal sending, thereby avoiding waste of resources and increased energy consumption. Accurate and fast control signal sending allows users to control the car ceiling TV more smoothly, improving the user's viewing experience. At the same time, because the system can automatically optimize the sending plan, users do not need to manually adjust parameters, reducing the difficulty of use.

[0090] In a preferred embodiment of the present invention, the calculation formula of the objective function is:

[0091]

[0092] Where F(x) represents the objective function value of the transmission scheme x; α, β, and γ represent weight coefficients; n represents the total number of transmitted signals; i represents the index variable; and w i represents the priority weight of the i-th type of signal; M i represents the number of successful transmissions of the i-th type of signal; N irepresents the total number of transmitted signals of type i; T(x) represents the response time of the control signal under the transmission scheme x; T max (x) represents the maximum response time under the sending scheme x; ∈, δ represent constants; m represents the number of stages in the sending process; P j represents the average power used in the jth stage of the transmission process; t j represents the duration of the jth stage in the sending process; E max (x) represents the maximum energy consumption of the device under the transmission scheme x.

[0093] In the embodiment of the present invention, the initialization parameters include weight coefficients (α, β, γ), the total number of transmitted signals n, and the priority weights w of various types of signals. i , the number of stages m in the sending process, and constants (∈, δ), etc. At the same time, a storage space is allocated for each sending scheme x to record various data in the iterative process, such as the number of successful transmissions (M i ), total number of sends (N i ), response time (T(x)), maximum response time (T max (x)) etc.

[0094] For each transmission scheme x, traverse all signal categories i and count the number of successful transmissions M of the i-th signal i And the total number of sent N i . The number of successful transmissions M i The total number of transmissions N can be determined by simulating transmission or receiving feedback after actual transmission. i is the total number of type i signals sent by the system. Record the response time T(x) of the control signal under each sending scheme x, that is, the time interval from sending the instruction to receiving the execution result. At the same time, calculate and record the maximum response time T max (x). For each stage j of the transmission process, the system records the average power P of that stage. j and duration t j .

[0095] Calculate the weighted successful transmission rate Response time ratio Energy consumption ratio And perform weighted summation according to the weight coefficients (α, β, γ). By simulating the foraging behavior of the fish school, the sending plan x is continuously updated and the objective function value F(x) is recalculated. When the preset number of iterations is reached, the iteration ends and the final sending plan is determined according to the objective function value. The final sending plan is saved and prepared for actual control signal sending.

[0096] By comprehensively considering multiple factors such as successful transmission rate, response time, and energy consumption, and performing weighted optimization, the system can find a more efficient control signal transmission solution and improve transmission efficiency. The weight coefficients and constants in the objective function can be adjusted according to actual needs, so that the system can adapt to different transmission scenarios and needs. By optimizing the average power and duration of the transmission process, the system can reduce the energy consumption of the equipment and extend the service life of the equipment while ensuring the successful transmission of the control signal. Shorter response time and higher successful transmission rate can enhance the user's control experience of the car ceiling TV, allowing users to enjoy the viewing process more smoothly.

[0097] In a preferred embodiment of the present invention, the above step 14, synchronizing the executed corresponding operation to the control unit in the vehicle cabin in real time, adjusting the state of the relevant equipment in the cabin to achieve linkage control with the vehicle ceiling TV, may include:

[0098] Step 141, setting an initial control parameter vector, and determining that the initial control parameter vector represents the initial state of each device in the cockpit;

[0099] Step 142, determining an evaluation function to evaluate the linkage control effect between the state of the equipment in the cabin and the state of the vehicle-mounted ceiling television, including response time, energy consumption, and passenger comfort indexes, and obtaining an evaluation result of the evaluation function;

[0100] Step 143, starting iterative optimization, in each iteration, selecting a direction from the coordinate directions for one-dimensional search, and continuously updating the control parameter vector according to the evaluation result of the evaluation function;

[0101] Step 144, after each iterative optimization, the updated control parameters are synchronized to the control unit in the vehicle cabin in real time, and the status of related equipment in the cabin is adjusted according to the updated control parameters to achieve linkage control with the vehicle-mounted ceiling TV.

[0102] In the embodiment of the present invention, a control parameter vector is defined, which contains the initial state parameters of each device in the cabin (such as lighting, air conditioning, audio, etc.). The initial state parameters can be the switch state, brightness, temperature, volume, etc. of the device, depending on the type of device. These initial state parameters are stored in the memory as the starting point of iterative optimization.

[0103] Step 142, construct an evaluation function to evaluate the linkage control effect between the device status in the cabin and the status of the vehicle-mounted ceiling TV. The evaluation function comprehensively considers the response time (i.e., the time from the issuance of the control command to the change of the device status), energy consumption (energy consumption of the device during operation), and passenger comfort indicators (such as light softness, temperature suitability, volume, etc.). Set a threshold or target value for the evaluation function to determine whether the linkage control effect meets expectations.

[0104] Step 143, start the iterative optimization process. In each iteration, select a direction from the coordinate direction of the control parameter vector for one-dimensional search. One-dimensional search means that the system only changes the value of one parameter on the basis of the current control parameter vector, while keeping other parameters unchanged, and then evaluates the control effect after the change. According to the evaluation result of the evaluation function, determine whether the current control parameter vector is better than the result of the previous iteration. If so, update the control parameter vector; if not, try to search in other directions. The iterative process continues until the preset number of iterations is reached and the evaluation function value reaches the preset threshold.

[0105] Step 144, after each iteration of optimization, the updated control parameter vector is immediately synchronized to the control unit in the vehicle cockpit in real time. After receiving the updated control parameters, the control unit immediately adjusts the status of the relevant equipment in the cockpit according to these parameters. The adjustment process includes changing the brightness of the lights, adjusting the temperature of the air conditioner, changing the volume of the audio, etc., which depends on the content of the control parameter vector. Through real-time synchronization and adjustment, the linkage control of the equipment in the cockpit and the vehicle ceiling TV is realized.

[0106] Assume that there is a dimmable reading light and a ceiling-mounted TV in the vehicle cabin. Initially, the brightness of the reading light is set to 50% and the TV is turned off. The evaluation function considers response time, energy consumption, and passenger comfort indicators. During the iterative optimization process, it was found that adjusting the brightness of the reading light to 70% and turning on the TV can provide better linkage control effects (such as faster response time, lower energy consumption, and higher passenger comfort). Therefore, in the next iteration, the system will update the control parameter vector and adjust the brightness of the reading light to 70%, while turning on the TV. In this way, when passengers are watching TV, the reading light can provide a suitable lighting environment, improving the overall riding experience.

[0107] Through iterative optimization and real-time synchronization of control parameters, the system can find the optimal linkage control scheme to improve the collaborative working effect between the equipment in the cabin and the on-board ceiling TV. The evaluation function takes into account the passenger comfort index, so the optimized linkage control scheme can better meet the needs of passengers and improve the riding experience. By optimizing the control parameters, the system can reduce the energy consumption of the equipment and extend the service life of the vehicle battery while ensuring the linkage control effect. The system can flexibly adjust the linkage control scheme according to actual needs and the setting of the evaluation function to adapt to different riding scenarios and passenger needs.

[0108] In a preferred embodiment of the present invention, the calculation formula of the evaluation function is:

[0109]

[0110] Where F represents the evaluation function; w1 represents the weight of the response time T; T represents the response time of the control signal; T e Indicates the reference response time of the control signal; c T An exponential parameter representing the response time; Q T Represents the amplitude of the periodic adjustment term of the response time; T max represents the maximum response time; w2 represents the weight of energy consumption; E represents the actual energy consumption; σ represents the pre-coefficient of the exponential parameter of energy consumption; E represents the actual energy consumption; U E represents the index parameter of energy consumption; w3 represents the weight of passenger comfort; C max Indicates the maximum value of passenger satisfaction; J max Indicates the maximum acceleration of the vehicle during driving; J t represents the acceleration threshold; w4, w5, w6 represent the weights of smoothness, cleanliness and noise level in the evaluation of passenger satisfaction; N d Indicates the stains detected in the vehicle; N t Indicates the threshold of stains; L n Indicates the average noise intensity value in the car; L t Indicates the average noise intensity threshold in the car; g C represents the exponential parameter of the passenger satisfaction evaluation part; e represents the base of the natural logarithm; l C represents the attenuation coefficient of the passenger satisfaction evaluation part; Y l Indicates the preset temperature value.

[0111] In the embodiment of the present invention, the initialization parameters include weight coefficients (w1, w2, w3), a reference value of the response time (T e ), exponential parameter of response time (c T ), the amplitude of the response time periodic adjustment term (Q T ), maximum response time (T max ), the pre-coefficient of the exponential parameter of energy consumption (σ), the exponential parameter of energy consumption (U E ), the maximum value of passenger satisfaction (C max ), acceleration threshold (J t ), the threshold of stains (N t ), the average noise intensity threshold in the car (L t ), index parameters of passenger satisfaction evaluation part (g C ), the attenuation coefficient of the passenger satisfaction evaluation part (l C ) and the preset temperature value (Y l ) etc. At the same time, it is the response time of the control signal (T), the actual energy consumption (E), the maximum acceleration of the vehicle during driving (J max ), stains detected in the car (N d), the average noise intensity value in the car (L n ) and other variables to allocate storage space for recording real-time data.

[0112] Through sensors or other monitoring equipment, the response time of the control signal (T), the actual energy consumption (E), the acceleration of the vehicle during driving (J), the stains in the car (N) are monitored in real time. d ) and the noise intensity inside the car (L n ) and other key data. Store the collected data in the corresponding variables. Calculate the ratio of the response time to the reference response time Then multiply it by the exponential parameter of the response time (c T ) and add the response time period adjustment item Get the response time component's evaluation value.

[0113] Calculate the actual energy consumption index (e σE -1), and then multiply it by the exponential parameter of energy consumption (U E ) to obtain the evaluation value of the energy consumption part.

[0114] The contribution of smoothness, cleanliness and noise level in passenger satisfaction evaluation is calculated by calculating and And multiply by the corresponding weight (w4, w5, w6) to achieve. Add the above three contributions and add 1 as the denominator of the logarithmic function. Next, calculate the maximum passenger satisfaction (C max ) and use it as the numerator. Finally, divide the numerator by the denominator and multiply the result by the exponential parameter (g C ), and multiply by the attenuation factor The exponential function of is used to obtain the evaluation value of the passenger comfort part.

[0115] The system multiplies the evaluation values ​​of the response time part, energy consumption part and passenger comfort part by the corresponding weights (w1, w2, w3), and then adds them together to obtain the comprehensive evaluation function value F(θ).

[0116] By comprehensively considering multiple factors such as response time, energy consumption, and passenger comfort, and constructing a comprehensive evaluation function for iterative optimization, the system can find a better control solution and improve the overall performance. By optimizing the response time of the control signal, the system can respond to the passenger's operating instructions more quickly and improve the user experience. By adjusting the control parameters related to energy consumption, the system can reduce the energy consumption of the equipment while ensuring performance and extend the service life of the vehicle battery. By optimizing passenger comfort indicators such as stability, cleanliness, and noise level, the system can provide passengers with a more comfortable and pleasant riding environment. The system can flexibly adjust the control solution according to actual needs and the setting of the evaluation function to adapt to different riding scenarios and passenger needs.

[0117] In a preferred embodiment of the present invention, the above step 15 monitors the status of the vehicle ceiling TV and the linkage control of related equipment in the cabin in real time, issues a warning message if an abnormality or failure occurs, and makes personalized adjustments to the linkage control rules based on the usage data to customize a specific viewing mode, including a cinema mode and a children's mode, which may include:

[0118] Step 151, continuously obtaining status information from the vehicle ceiling TV and related equipment in the cabin, including the audio system, the lighting system, and the seat adjustment system; the status information includes the switch status of the TV, the current playing content, the volume level, the screen brightness, and the current configuration and status of the equipment in the cabin;

[0119] Step 152, using anomaly detection logic, judging whether the vehicle-mounted ceiling TV or the equipment in the cabin has an abnormality or fault according to preset rules and thresholds, and if an abnormality or fault is detected, issuing a warning message, including displaying a warning message on the vehicle-mounted display screen or issuing a warning sound through the audio system;

[0120] Step 153, in a normal state, obtaining usage data of the vehicle ceiling TV and the equipment in the cabin in real time, including user preferences, viewing history, and device adjustment frequency, and analyzing the usage data to identify user behavior patterns and preferences to obtain data analysis results;

[0121] Step 154, based on the data analysis results, automatically adjust the linkage control rules and set options for the user, including theater mode and children's mode or customize a new viewing mode based on preference.

[0122] In an embodiment of the present invention, during initialization, a communication connection is established with the vehicle-mounted ceiling TV and related equipment in the cabin (such as the audio system, lighting system, and seat adjustment system). A timed task or event-driven mechanism is set to obtain status information from these devices regularly or in real time. The status information includes but is not limited to the switch status of the TV, the current playback content (such as the channel, program name, playback progress), volume level, screen brightness, and the current configuration and status of the equipment in the cabin (such as the sound effect mode of the audio, the brightness and color of the lights, the tilt angle of the seat and the massage function, etc.). The acquired status information is stored in the memory or in a database.

[0123] Step 152, define a set of abnormality detection logic, including preset rules and thresholds. For example, set the inability of the TV to respond to control instructions as an abnormality, or the volume level exceeding a certain set threshold as a fault. The system judges the acquired status information in real time according to these rules and thresholds. If an abnormality or fault is detected, the system immediately triggers a warning mechanism. The warning can display a warning message on the vehicle display screen (such as "TV connection abnormality, please check"), or emit a specific warning sound through the audio system. At the same time, the system can record information about the abnormality or fault, including the time of occurrence, specific abnormality or fault type, etc.

[0124] Step 153, under normal conditions, the system continuously collects usage data of the vehicle ceiling TV and in-cabin equipment. The usage data includes but is not limited to user preferences (such as favorite program types, volume preferences, lighting effects, etc.), viewing history (such as watched programs, viewing time, etc.) and device adjustment frequency (such as how often users adjust seats, volume, etc.). These usage data are cleaned, sorted and analyzed, and data mining and machine learning techniques are used to identify user behavior patterns and preferences. The analysis results can be user-centric portraits, including user viewing habits, preference settings, etc.

[0125] Step 154, based on the data analysis results, the system automatically adjusts the linkage control rules. For example, if the user prefers high volume and dimmed lights, the system can automatically turn up the volume and dim the lights while the user is watching. Provide users with a selection interface so that they can select preset viewing modes (such as theater mode, children's mode) or customize new viewing modes according to their preferences. When the user selects a specific viewing mode, the system automatically adjusts the status of the vehicle-mounted ceiling TV and the equipment in the cabin according to the configuration of the mode to meet the user's personalized needs. At the same time, the system can record the user's mode selection and usage in order to continuously optimize and update the viewing mode.

[0126] Suppose there is a smart car equipped with an advanced ceiling-mounted TV, sound system, lighting system, and seat adjustment system. These systems can be managed and controlled uniformly through the in-vehicle smart system.

[0127] When the car is started for the first time, the in-vehicle intelligent system will automatically initialize and communicate with devices such as TV, audio, lights, and seats. Then, set a timer task to obtain status information from these devices at regular intervals (such as every second or every few minutes). For example, the system will know whether the TV is currently on or off, which channel or program is playing, what the volume level is, and how bright the screen is; at the same time, it will also collect information such as the sound effect mode of the audio, the brightness and color of the lights, the tilt angle of the seat, and whether the massage function is turned on. This information will be stored in the system's memory in real time. A set of abnormality detection logic is built in. For example, if the TV cannot respond to the system's control instructions, or the volume level suddenly exceeds the preset safety threshold (such as 100 decibels), the system will immediately determine it as an abnormality or fault and trigger a warning mechanism. You may see a warning message on the car display: "The TV connection is abnormal, please check", or hear a specific warning sound from the audio system. At the same time, the system will record the information of this abnormality or fault, including the time of occurrence, the specific abnormality or fault type, etc., for subsequent troubleshooting and repair.

[0128] Under normal circumstances, the system will continue to collect data about the use of in-vehicle devices. For example, the system will record the types of programs frequently watched, the preferred volume levels and lighting effects, and the frequency of adjusting seats and volume. By cleaning, sorting and analyzing this data, the system can identify behavioral patterns and preferences. For example, the system may find that every time you watch a movie, you like to turn up the volume and dim the lights.

[0129] Based on the analysis of behavioral patterns and preferences, the system automatically adjusts the linkage control rules. The next time you watch a movie, the system will automatically turn up the volume to your preferred level and dim the lights to a brightness suitable for watching movies. At the same time, the system will also provide you with a selection interface, where you can choose a preset viewing mode (such as theater mode, children's mode), or customize a new viewing mode according to your preferences. For example, you can set a "family mode", in which the system will automatically adjust the status of the TV, audio, lighting and seats according to your preferences to create a comfortable viewing environment for yourself and your family. When this mode is selected, the system will automatically adjust the device status according to the preset configuration. At the same time, your mode selection and usage will be recorded in order to continuously optimize and update the viewing mode to better meet your personalized needs. Through real-time monitoring and personalized adjustments, the system can provide users with a viewing experience that is more in line with their preferences and needs, thereby improving user satisfaction and loyalty.

[0130] The anomaly detection mechanism can promptly detect and handle anomalies or faults of the vehicle-mounted ceiling TV and equipment in the cabin, ensuring the stable operation and reliability of the system. Through data analysis and machine learning technology, the system can continuously learn and optimize linkage control rules to improve the intelligence and automation level of the system. The system can provide personalized viewing modes and services based on user preferences and needs, providing strong support for the development of personalized services in the future.
