Description

Technical Field

[0001] This application relates to the field of intelligent vehicle technology, specifically to an intelligent headrest system, a headrest control method, and a vehicle. Background Technology

[0002] Modern car design increasingly prioritizes passenger comfort and safety, especially during long drives where passengers often maintain a seated posture for extended periods, leading to neck fatigue and discomfort. Rear-seat passengers, in particular, frequently sleep in slumbering positions, impacting overall comfort and safety. However, most car headrests currently on the market employ a fixed design, failing to adjust flexibly to different passenger shapes and postures, resulting in several key problems: Insufficient support: Traditional fixed headrests cannot provide sufficient support for the head and neck, especially during long journeys or when passengers change their sitting posture, easily causing neck fatigue and discomfort. As passengers' sitting posture changes, fixed headrests cannot adjust in real time, resulting in a significant reduction in support effectiveness.

[0003] Limited comfort: Fixed headrests cannot be adjusted to accommodate individual passenger differences, especially when passengers are resting or sleeping. Traditional headrests fail to provide the necessary stability and comfort, easily causing neck and head discomfort. The fixed design of the headrest's height and angle cannot meet the needs of different passengers, resulting in a significant reduction in comfort.

[0004] Low level of intelligence: Most existing car headrests still use traditional mechanical structures and lack intelligent adjustment functions. This structure cannot be personalized according to the passenger's real-time needs or changes in body posture, and cannot provide passengers with more humanized and personalized services. Due to the lack of sensors and automatic adjustment functions, passengers cannot obtain the optimal comfort experience under different driving conditions. Summary of the Invention

[0005] To address the above technical problems, this application provides an intelligent headrest system, a headrest control method, and a vehicle.

[0006] In a first aspect, this application proposes an intelligent headrest system, the intelligent headrest system comprising: Sensors are used to monitor passengers' posture information in real time; The vehicle control module is connected to the sensor and is used to receive and transmit the body posture information; The intelligent headrest module is connected to the vehicle control module and includes multiple independently controllable inflatable airbag units and airbag adjustment units. The vehicle control module transmits the received body posture information to the smart headrest module in real time. The headrest module triggers the airbag adjustment unit based on the body posture information, and the airbag adjustment unit adjusts the inflation of each airbag unit based on the body posture information.

[0007] This intelligent headrest system uses OMS sensors to monitor passengers' posture, head tilt angle, and body shape in real time, enabling personalized head support. The headrest automatically adjusts according to the passenger's body movements, providing a more comfortable riding experience. The intelligent headrest module's design allows the inflatable airbag unit to be independently adjustable, fully adapting to the needs of different passengers and thus optimizing comfort. Through automatic adjustment, the intelligent headrest system also enhances riding safety, preventing neck or back discomfort caused by improper posture.

[0008] Furthermore, the intelligent headrest system also includes: The control information receiving module is connected to the vehicle control module and is used to receive control commands input by the passenger. The vehicle control module transmits the control commands to the smart headrest module, and the smart headrest module, according to the command, transmits the commands to the smart headrest module. The control command triggers the airbag adjustment unit to adjust the corresponding inflatable airbag unit.

[0009] The system can also receive passenger commands through the control information receiving module and transmit the commands to the vehicle control module. The intelligent headrest module then adjusts the inflatable airbag unit according to the commands, thereby achieving personalized headrest adjustment from multiple angles and improving passenger comfort and experience.

[0010] Furthermore, the intelligent headrest system also includes: The display screen, connected to the vehicle control module, is used to display at least one parameter information in real time, including airbag pressure value, adjustment status, and passenger body shape matching degree.

[0011] The display screen can show key information such as airbag pressure, adjustment status, and passenger body fit in real time, helping passengers understand the headrest's working status at any time. Through the intuitive feedback on the display screen, passengers can better understand and adjust the headrest settings to ensure that its comfort matches their individual needs. The display screen connects to the vehicle's infotainment module, enabling more precise display and adjustment of relevant parameters, enhancing the system's intelligent operation and adjustment accuracy.

[0012] Furthermore, the intelligent headrest system also includes: The cloud platform server module is communicatively connected to the smart headrest module and is used to store passengers' historical body posture information and generate personalized preference models.

[0013] Furthermore, the intelligent headrest system also includes: The smart headrest module calls the personalized preference model as the baseline state for multiple independently controllable inflatable airbag units.

[0014] The cloud platform server module stores passengers' historical posture information and generates personalized preference models based on this information, helping the system more accurately meet passengers' comfort needs. The intelligent headrest module can use these personalized preference models as a baseline state for multiple inflatable airbag units, ensuring that each adjustment is automatically optimized according to the passenger's unique needs. With the support of historical posture information and personalized models, the system can provide more precise and customized headrest adjustments, continuously improving passenger comfort. The system can gradually adjust as passenger needs change, forming an adaptive adjustment mode to ensure comfort and satisfaction over long-term use.

[0015] Furthermore, the smart headrest module also includes an audio adjustment unit, which integrates a directional speaker array that dynamically adjusts the sound field distribution according to the passenger's head position.

[0016] The integrated directional speaker array in the audio adjustment unit dynamically adjusts the sound field distribution based on the passenger's head position, providing more precise sound localization and enabling passengers to enjoy a personalized, immersive audio experience. By dynamically adjusting the sound field, interference from other passengers in the vehicle is effectively reduced, ensuring clear, undisturbed sound for every passenger. Based on changes in the passenger's head position, the directional speaker array intelligently adjusts the direction and intensity of sound propagation, achieving adaptive audio adjustment and enhancing the user experience of the in-vehicle entertainment system. Combined with the headrest adjustment function and audio system optimization, passengers can achieve a higher level of comfort and enjoy more personalized and refined services during long journeys.

[0017] Secondly, this application proposes a headrest control method, which includes the following steps: S1: Real-time collection of passenger posture information; S2: Based on the body posture information, generate target airbag pressure distribution parameters using a preset adaptation algorithm; S3: Inflate multiple independent airbag units according to the target airbag pressure distribution parameters to make the headrest shape... The shape dynamically adapts to the passenger's head contour.

[0018] By collecting real-time information on passengers' posture, head tilt angle, and body shape, the system can dynamically adjust the headrest shape according to each passenger's individual needs, enhancing comfort. Based on a preset adaptation algorithm, the system can automatically calculate and generate target airbag pressure distribution parameters, enabling precise adjustment of the airbag units and ensuring the headrest dynamically adapts to changes in the passenger's head contour. Each passenger receives adjustments tailored to their unique head shape and posture, ensuring the headrest not only provides comfortable support but also effectively prevents discomfort caused by an unsuitable seat shape, especially during long journeys. Dynamically adjusting the headrest shape not only increases comfort but also provides better head support in emergencies, reducing the risk of head injury. As passengers' body shape and posture change, the system continuously adapts in real-time, maintaining the optimal headrest shape and providing a consistently comfortable experience.

[0019] Furthermore, the headrest control method also includes: acquiring the passenger's operation command and adjusting the corresponding inflatable airbag unit according to the operation command.

[0020] By receiving passenger input, passengers can manually adjust the headrest airbag units according to their individual comfort needs, achieving a higher level of personalized adjustment. For example, passengers can increase or decrease the inflation of certain airbags based on their sitting posture or preferences to obtain the most suitable support. Passengers' direct control over airbag adjustments provides a more flexible and free choice, meeting the immediate comfort needs of different passengers in different situations, especially during long journeys or in various sitting postures, allowing them to optimize the headrest shape themselves. The addition of input commands makes the system more responsive, quickly adjusting based on passenger feedback to continuously optimize comfort and provide a consistently comfortable experience throughout the journey.

[0021] Furthermore, the headrest control method also includes: storing the passenger's historical body posture information and generating a personalized preference model, which is then set as the initial target airbag pressure distribution parameters.

[0022] By storing passengers' historical posture information and generating personalized preference models, the system remembers each passenger's preferences and provides customized headrest adjustments for each ride. This eliminates the need for passengers to reset their headrests each time; they can enjoy a more comfortable experience simply by relying on the system's automatically stored preference model. The system intelligently generates the most suitable target airbag pressure distribution parameters based on past posture information, enabling quick and accurate headrest adjustments for each ride. This automated optimization significantly reduces the hassle of manual operation and improves convenience. As historical posture information accumulates with each ride, the system continuously optimizes the passenger's headrest experience, providing optimal comfort based on their past adjustment habits, thereby increasing passenger satisfaction and loyalty.

[0023] Thirdly, this application proposes a vehicle including the intelligent headrest system as described in the first aspect; the vehicle further includes a computer-readable storage medium storing computer-executable instructions, which, when executed by a control processor, implement the headrest control method as described in the second aspect.

[0024] In summary, this invention relates to an intelligent headrest system designed to provide customized comfort support by real-time sensing of a passenger's posture, head tilt angle, and body shape. The system includes an OMS sensor, an in-vehicle control module, and an intelligent headrest module. The OMS sensor collects real-time information on the passenger's posture and body shape. The in-vehicle control module, connected to the OMS sensor, receives and processes this posture information. The intelligent headrest module, connected to the in-vehicle control module, incorporates multiple independently adjustable inflatable airbag units and airbag adjustment units. The in-vehicle control module transmits the real-time posture information collected by the sensor to the intelligent headrest module. Based on this posture information, the intelligent headrest module adjusts the inflation volume of the airbags, thereby precisely adjusting the headrest's support force to provide optimal comfort and support.

[0025] Compared with the prior art, this application has at least the following beneficial effects: This system can automatically adjust the headrest support based on changes in the passenger's posture, significantly improving comfort and safety during long drives. Attached Figure Description

[0026] Figure 1 This is a schematic diagram of an intelligent headrest system shown in an embodiment of this application.

[0027] Figure 2 This is a flowchart illustrating the headrest control method in an embodiment of this application. Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] Example 1: As attached Figure 1 As shown, this application proposes an intelligent headrest system, the intelligent headrest system comprising: Sensors are used to monitor passengers' posture, head tilt angle, and body shape characteristics in real time. The vehicle control module is connected to the sensor and is used to receive and transmit the body posture information; The intelligent headrest module is connected to the vehicle control module and includes multiple independently controllable inflatable airbag units and airbag adjustment units. The vehicle control module transmits the received body posture information to the smart headrest module in real time. The smart headrest module triggers the airbag adjustment unit based on the body posture information, and the airbag adjustment unit adjusts the inflation of each airbag unit based on the body posture information.

[0030] In this embodiment of the invention, the OMS sensor may utilize optical sensors (such as infrared, laser, or cameras) to capture changes in the passenger's posture and analyze the position and angle changes of various body parts. This posture information can help the system identify whether the passenger's sitting posture is correct, whether the head is off-center, whether the neck needs more support, etc., and transmit this posture information to the vehicle control module so as to adjust the airbag unit in the smart headrest module to provide the best support effect.

[0031] An OMS (Optical Motion Sensing Sensor) is a motion sensing sensor based on optical technology, typically used to monitor and analyze the movement, posture, and position of objects (such as the human body). It acquires motion-related postural information by capturing the object's movement in space. In smart headrest systems, OMS sensors can use optical principles to monitor a passenger's sitting posture, head tilt angle, and body shape characteristics in real time.

[0032] As a preferred embodiment, the working process of the smart headrest system is as follows: Once passengers enter the vehicle and adjust their seats, the OMS sensors begin real-time monitoring of their posture, head tilt angle, and body shape. This postural information includes physiological data such as the passenger's spinal angle, head tilt, shoulder height, and neck curvature.

[0033] The vehicle's infotainment system (VIS) module connects to the OMS sensors, receiving and processing the body posture information collected by the sensors. It analyzes this body posture information in real time to identify the passenger's posture, such as whether there is discomfort caused by long-term driving or misalignment of the head and back.

[0034] The vehicle's infotainment system transmits processed posture information to the smart headrest module. Upon receiving this information, the smart headrest module immediately makes precise adjustments based on the passenger's posture. Multiple inflatable airbags within the smart headrest module begin adjusting according to the posture information transmitted from the infotainment system. For example, if sensors detect that the passenger's head is tilted forward or their posture is incorrect, the smart headrest module automatically inflates the corresponding airbag to provide better head support and help correct their posture.

[0035] The intelligent headrest module adjusts the inflation volume of each airbag unit through the airbag adjustment unit to achieve the best comfort support. For example, if the passenger's neck needs more support, the airbag adjustment unit will increase the inflation volume of the airbag in the neck area and reduce pressure on other parts to ensure the natural alignment of the head and spine.

[0036] In an embodiment of the present invention, optionally, the intelligent headrest system further includes: The control information receiving module is connected to the vehicle control module and is used to receive control commands input by the passenger. The vehicle control module transmits the control commands to the smart headrest module, and the smart headrest module, according to the command, transmits the commands to the smart headrest module. The control command triggers the airbag adjustment unit to adjust the corresponding inflatable airbag unit.

[0037] In a preferred embodiment, the control information receiving module is connected to the vehicle control module, through which passengers can input control commands. Control information can be input via a touchscreen, voice recognition, buttons, etc. For example, passengers can choose to adjust the headrest height, change the pillow angle, or adjust the support strength, etc.

[0038] After receiving the control commands input by the passenger, the vehicle's infotainment system (V2S) module transmits these commands to the smart headrest module. The V2S module then uses the vehicle network to convert the commands into signals that the headrest module can recognize. During this process, the V2S module may also perform some data processing and command parsing to ensure the accuracy of the commands.

[0039] When the smart headrest module receives a control command from the vehicle's infotainment system, it triggers the airbag adjustment unit according to the command. The airbag adjustment unit adjusts the corresponding inflatable airbag unit based on the passenger's needs. For example, if the passenger chooses to increase the headrest support, the smart headrest module will activate the airbag adjustment unit to increase the headrest support by inflating it; if the passenger wants a more comfortable experience, the airbag pressure can be reduced to decrease the headrest's firmness.

[0040] Imagine a passenger experiencing head discomfort and deciding to adjust the headrest height and support. The passenger inputs a command via the touchscreen, selecting to increase the headrest height and support. The system first receives this command through the control information receiving module, then the vehicle control module transmits the command to the intelligent headrest module. The intelligent headrest module adjusts the airbag inflation accordingly, making the headrest more firm and comfortable. This process enables personalized adjustment of headrest height and support, enhancing the passenger experience.

[0041] In an embodiment of the present invention, optionally, the intelligent headrest system further includes: The display screen, connected to the vehicle control module, is used to display at least one parameter information in real time, including airbag pressure value, adjustment status, and passenger body shape matching degree.

[0042] In a preferred embodiment, the display screen can display: Airbag pressure: Displays the current airbag inflation pressure. This parameter helps passengers understand the headrest's support level.

[0043] For example, when the airbag inflation pressure is high, the headrest becomes firmer and provides more support; while when the airbag pressure is low, the headrest becomes softer and provides a more comfortable experience.

[0044] Adjustment Status: Displays the current headrest adjustment status, including headrest height, angle, and firmness. For example, the display can show "Headrest Height: High" or "Angle: Tilted 15 degrees," clearly informing passengers of the current headrest settings.

[0045] Passenger Body Fit: Displays the degree to which the headrest is personalized and adjusted according to the passenger's body shape (such as neck curve, head size, etc.). The system analyzes the passenger's body shape through sensors or preset algorithms and calculates the optimal headrest setting, displaying the fit degree on the screen. If the fit degree is low, the system may recommend adjusting the headrest height or angle.

[0046] When passengers want to adjust the height or angle of the headrest, they can input the corresponding command via touchscreen or voice command, and the display screen will show the result of the operation in real time. For example, if a passenger selects to adjust the headrest angle, the display screen can show "Adjust angle: +10 degrees," letting the passenger know that their operation has been accepted and executed by the system.

[0047] If a passenger's body type is not well-suited to the headrest, the display screen will provide suggestions such as "Adjust the headrest height to better suit your body type" to help the passenger optimize their comfort.

[0048] Imagine a passenger gets into the car and wants to adjust the headrest for better comfort. They input the command "increase headrest support" via the in-car touchscreen. The vehicle's control module transmits the command to the intelligent headrest module, and the display shows the current airbag pressure value in real time, such as "Airbag pressure: 320Pa," and the current headrest adjustment status: "Headrest angle: 15 degrees tilt, support: medium." At this time, the passenger will also see a "Body fit: 85%" prompt, indicating that the headrest setting matches their body shape and provides good support.

[0049] In an embodiment of the present invention, optionally, the intelligent headrest system further includes: The cloud platform server module is communicatively connected to the smart headrest module, and is used to store the passenger's historical adjustment posture information and generate... Personalized preference model.

[0050] In an embodiment of the present invention, optionally, the intelligent headrest system further includes: The smart headrest module calls the personalized preference model as the baseline state for multiple independently controllable inflatable airbag units.

[0051] As a preferred embodiment, the cloud platform server can record the history of passenger headrest adjustments in different riding scenarios, such as headrest height, angle, and airbag pressure. Through long-term accumulation, the cloud platform can understand passenger preferences and habits, generating a more accurate personalized preference model.

[0052] Generating personalized preference models: The system analyzes passengers' historical posture information to determine their preferences for headrest comfort. For example, some passengers may prefer softer headrests, while others prefer firmer ones. Through machine learning algorithms on the cloud platform, this historical posture information can be transformed into personalized models as a reference for future adjustments.

[0053] In a preferred embodiment, each passenger's personalized preference model defines a set of recommended baseline settings. These baseline settings include the headrest angle, firmness (via airbag inflation), and height. The smart headrest module automatically adjusts the airbag unit to meet these settings. When a passenger boards, the system automatically reads the passenger's personalized preference model from the cloud platform, and the smart headrest module adjusts the headrest settings accordingly. For example, if a passenger has previously preferred a lower headrest height and softer support, the system will automatically adjust the airbag pressure to keep the headrest in their most comfortable position. If a passenger's preferences change during a ride, the smart headrest module can record the change in real time and upload it to the cloud platform for updates. The system will then adjust based on the latest preference model for the next ride.

[0054] For example, passenger A habitually sets the headrest to a softer, lower height, and saves this historical adjustment and preference model on the cloud platform. On the next ride, the system reads passenger A's personalized preference model and automatically adjusts the headrest angle, airbag pressure, and height to perfectly match passenger A's preferences. Passenger A doesn't need to manually adjust anything; the system provides a comfortable, personalized experience.

[0055] In an embodiment of the present invention, optionally, the smart headrest module further includes an audio adjustment unit, which integrates a directional speaker array, and the directional speaker array dynamically adjusts the sound field distribution according to the position of the passenger's head.

[0056] In a preferred embodiment, the array consists of multiple small speaker units that can precisely control sound waves to directionally deliver audio signals to the passenger's ears without affecting other passengers or the vehicle's interior environment. The speaker array can dynamically adjust the volume and direction of the audio signal for each speaker based on the passenger's head position, ensuring the passenger hears clear, immersive sound.

[0057] When passengers change their sitting posture or head position inside the vehicle, the audio adjustment unit monitors and analyzes the passenger's head position in real time and automatically adjusts the output sound field of the speaker array. In this way, no matter how the passenger adjusts their sitting posture or turns their head, the audio positioning remains accurate, ensuring that the passenger receives the best audio experience.

[0058] The audio adjustment unit can be customized to suit individual passenger preferences. For example, passenger A might prefer clear high-frequency sound, while passenger B might prefer immersive low-frequency sound. Through historical adjustments and user feedback, the audio adjustment unit can adjust the audio output characteristics of the speaker array according to passenger preferences.

[0059] Suppose passenger A is seated in the car and has adjusted the headrest height. When passenger A's head position changes, the audio adjustment unit detects the change using built-in sensors and automatically adjusts the output direction and volume of the directional speaker array. For example, when passenger A turns their head slightly, the audio adjustment unit can precisely direct the sound to passenger A's ears without affecting the experience of other passengers in the car.

[0060] Example 2: As attached Figure 2 As shown, this application also proposes a headrest control method, which includes the following steps: S1: Real-time collection of passenger posture information, such as passenger sitting posture, head tilt angle and body shape characteristics; S2: Based on the body posture information, generate target airbag pressure distribution parameters using a preset adaptation algorithm; S3: Inflate multiple independent airbag units according to the target airbag pressure distribution parameters to make the headrest shape... The shape dynamically adapts to the passenger's head contour.

[0061] In an embodiment of the present invention, optionally, the headrest control method further includes: acquiring the passenger's operation command and adjusting the corresponding inflatable airbag unit according to the operation command.

[0062] In an embodiment of the present invention, optionally, the headrest control method further includes: storing passenger historical adjustment posture information and generating a personalized preference model, which is set as the initial target airbag pressure distribution parameter.

[0063] In a preferred embodiment, the system monitors the passenger's sitting posture and head position and tilt angle in real time. In addition, it collects the passenger's body shape data (such as neck width and head size). This postural information provides a basis for subsequent headrest adjustments and can accurately capture dynamic changes in the passenger's sitting posture.

[0064] Based on the body posture information, target airbag pressure distribution parameters are generated using a preset adaptation algorithm.

[0065] Based on the body posture information collected in step S1, a preset adaptation algorithm is used to analyze and calculate the target airbag pressure distribution parameters suitable for the current passenger's head contour.

[0066] The adaptation algorithm optimizes the airbag pressure distribution based on the passenger's sitting posture, head angle, and body shape, ensuring that the headrest can accurately adapt to the contour of the passenger's head and provide optimal comfort.

[0067] Based on the target airbag pressure distribution parameters generated in step S2, multiple independent inflatable airbag units are controlled to inflate or deflate. The inflation volume of these airbags is adjusted according to the position and contour changes of the passenger's head, so that the shape of the headrest can dynamically adapt to the passenger's head.

[0068] Each airbag unit is independently adjusted according to pressure distribution parameters to ensure that the passenger's head is always in the optimal comfort zone within the headrest.

[0069] As an optional embodiment, passengers can input operating commands via buttons, touchscreens, or voice control to adjust the firmness or shape of the headrest. These commands may include changing the support strength of the headrest, adjusting the inflation status of the airbag, etc.

[0070] Based on the passenger's operating instructions, the system will adjust the inflation volume of the relevant airbag units in real time, thereby quickly changing the shape or comfort of the headrest to meet individual needs.

[0071] As an optional embodiment, the system can store passengers' historical posture information and generate a personalized preference model, which is then set as the initial target airbag pressure distribution parameters. The headrest control system builds a personalized preference model based on passengers' usage habits and historical adjustment records. This historical postural information includes the passenger's previous sitting posture, head tilt angle, and preference settings.

[0072] The system will automatically adjust the airbag pressure distribution parameters based on historical body posture information when the passenger rides again, in order to provide a headrest setting that better suits the passenger's personal preferences. In this way, passengers do not need to manually adjust it every time, as the system will automatically optimize it.

[0073] Example 3: This application proposes a vehicle that includes the intelligent headrest system as described in Embodiment 1; the vehicle further includes a computer-readable storage medium storing computer-executable instructions, which, when executed by a control processor, implement the headrest control method as described in Embodiment 2.

[0074] It should be noted that since the computer-readable storage medium in this embodiment is based on the same inventive concept as the headrest control method in the above embodiments, the corresponding content in the method embodiment is also applicable to this system embodiment, and will not be described in detail here.

[0075] In summary, this invention relates to an intelligent headrest system designed to provide customized comfort support by real-time sensing of a passenger's posture, head tilt angle, and body shape. The system includes an OMS sensor, an in-vehicle control module, and an intelligent headrest module. The OMS sensor collects real-time information on the passenger's posture and body shape. The in-vehicle control module, connected to the OMS sensor, receives and processes this posture information. The intelligent headrest module, connected to the in-vehicle control module, incorporates multiple independently adjustable inflatable airbag units and airbag adjustment units. The in-vehicle control module transmits the real-time posture information collected by the sensor to the intelligent headrest module. Based on this posture information, the intelligent headrest module adjusts the inflation volume of the airbags, thereby precisely adjusting the headrest's support force to provide optimal comfort and support.

[0076] This system can automatically adjust the headrest support based on changes in the passenger's posture, significantly improving comfort and safety during long drives.
