Description

Technical Field

[0001] This invention relates to the field of intelligent car seats, specifically to a car seat control system and method with haptic music therapy function, and a car seat. Background Technology

[0002] With the increasing demand for intelligent and health-oriented vehicles, automotive seat systems are evolving from a single function of providing comfort to multimodal comfort and health management. Currently, the application of seat vibration devices is mainly concentrated in two scenarios: 1. safety warning systems, and 2. entertainment experience enhancement. Current research and market applications show that seat vibration device applications are gradually entering the field of health and comfort.

[0003] In my country, office workers in major cities like Beijing, Shanghai, Guangzhou, and Shenzhen sit for an average of 8.1 hours a day, with the 35-44 age group experiencing this 29% higher rate than the 18-34 age group. Even before getting into their cars after work, drivers commonly experience deep muscle and joint discomfort symptoms caused by prolonged sitting, such as increased pressure on the lumbar spine and patellofemoral joint, neck and shoulder strain, and gluteal muscle inhibition. Based on this situation, research in the medical and health field has shown that specific frequencies of somatosensory vibration (16–150Hz) can induce a bioresonance effect in the human body through bone conduction: low-frequency sound waves, after amplification, drive cells to vibrate at the same frequency, promoting endorphin secretion and inhibiting cortisol production, thereby reducing muscle tension and anxiety levels. This technology can be applied to physiological relaxation solutions for drivers and passengers, addressing issues related to muscles and joints.

[0004] In existing technologies, a multimodal acoustic vibration system is used to cover the headrest, backrest, and base in three-frequency layers, solving the problems of dispersed sound field and weak immersion in traditional car audio systems. A hybrid exciter is embedded in a pressure-sensitive area to match the body's pressure distribution and expand the therapeutic modes. A low-frequency vibration mode is triggered when the backrest tilts >30°, achieving multi-sensory synergistic healing. However, this solution has several drawbacks. First, while the multimodal acoustic vibration system enhances immersion, it may place high demands on vehicle space design. Second, the therapeutic modes of the hybrid exciter in the pressure-sensitive area are limited, failing to meet the needs of all users. Third, the conditions for triggering low-frequency vibration when the backrest tilts are relatively simple, lacking intelligent dynamic adjustment capabilities. Summary of the Invention

[0005] The purpose of this invention is to provide a car seat control system, method, and seat with haptic music therapy function. This system, method, and seat can integrate multiple hybrid exciters in key parts of the car seat and utilize resonant frequency sound therapy technology from the medical field to provide services to relieve physiological fatigue according to the driving and riding scenarios and the needs of users in different short and long-term stages.

[0006] To achieve this objective, the present invention provides a car seat control system with haptic music therapy function, comprising:

[0007] The intelligent car seat hybrid exciter is used to acquire user posture data and execute healing mode commands in either the parking state or the forward state.

[0008] The healing decision module is used to determine whether the vehicle is in a parked state based on the vehicle's gear and speed. When the vehicle is parked, it generates a parking state healing mode command based on the current backrest angle of the smart car seat, the current user's sitting posture data, and the user's physiological data. It also adjusts the amplitude of the smart car seat hybrid exciter based on the user's sitting posture data fed back by the smart car seat hybrid exciter under the parking state healing mode command.

[0009] When the vehicle is moving forward, a forward-moving healing mode command is generated based on the current user's seating posture data to control the working state of the car's intelligent seat hybrid exciter. The amplitude of the car's intelligent seat hybrid exciter is adjusted based on the current vehicle steering wheel angle, the current vehicle acceleration, and the user's seating posture data fed back by the car's intelligent seat hybrid exciter under the forward-moving healing mode command.

[0010] Furthermore, when the vehicle is in reverse gear and the speed is greater than 0, the hybrid exciter of the car's intelligent seat will be shut down.

[0011] Furthermore, methods for obtaining user sitting posture data include: installing a car smart seat hybrid exciter on the car seat base and backrest to collect pressure data of the user's scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle in real time;

[0012] Methods for obtaining user physiological data include: setting up bioelectrical sensing electrodes on the car steering wheel to collect the user's skin conductance response data and heart rate variability data in real time.

[0013] Furthermore, when the vehicle is parked, the method for generating parking state healing mode instructions to control the operation of the vehicle's smart seat hybrid exciter based on the current backrest angle of the smart seat, the current user's sitting posture data, and the user's physiological data includes:

[0014] F(P)=MAX(|Ps-Ps0| / σs,|Pl-Pl0| / σl,|Pi-Pi0| / σi,|Pc-Pc0| / σc);

[0015] F(EDA) = |EDA - EDA0| / σeda;

[0016] F(HRV) = |HRV0 - HRV| / HRV0;

[0017] When MAX(F(P),F(EDA),F(HRV))>T1, it is recommended that users use the stress relief and healing mode;

[0018] Wherein, F(P) is the maximum standardized deviation of the real-time pressure values ​​at the user's scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle from the corresponding resting baseline pressure values; F(EDA) is the standardized deviation of the user's real-time skin conductance response value from the resting baseline skin conductance response value; F(HRV) is the relative decrease ratio of the user's real-time heart rate variability value to the optimal baseline heart rate variability value; Ps is the real-time pressure value at the user's scapula; Pl is the real-time pressure value at the user's lumbar spine; Pi is the real-time pressure value at the user's sciatic nerve; Pc is the real-time pressure value at the user's gastrocnemius muscle; Ps0 is the user's baseline resting pressure at the scapula; and Pl0 is the user's resting pressure at the lumbar spine. Baseline values: Pi0 is the baseline value of sit pressure at the sciatic nerve, Pc0 is the baseline value of sit pressure at the user's gastrocnemius muscle; σs is the standard deviation of sit pressure at the user's scapula, σl is the standard deviation of sit pressure at the user's lumbar spine, σi is the standard deviation of sit pressure at the user's sciatic nerve, σc is the standard deviation of sit pressure at the user's gastrocnemius muscle; EDA is the user's real-time skin conductance response value, EDA0 is the baseline value of the user's skin conductance response, σeda is the standard deviation of the user's skin conductance response; HRV is the user's real-time heart rate variability value; HRV0 is the baseline value of the user's heart rate variability; T1 is the trigger threshold of the stress relief therapy mode, MAX(.) is the maximum value function;

[0019] If the user selects the stress relief mode for more than the set time or the posture sensor detects that the backrest tilt angle of the car seat gyroscope is greater than the set value, it is recommended that the user select to activate the music therapy bed mode.

[0020] Furthermore, when performing body healing on the user in the stress relief and healing mode, the mixed stimulators at the user's shoulder blades, lumbar spine, sciatic nerve, and gastrocnemius muscles vibrate and massage along the set massage sequence of the shoulder blades, lumbar spine, sciatic nerve, and gastrocnemius muscles at preset intervals, using the set stress relief and healing mode frequency and amplitude.

[0021] Furthermore, when the music therapy bed mode begins, the car's intelligent seat hybrid exciter plays meditation music. The hybrid exciter at the user's shoulder blades, lumbar spine, sciatic nerve, and gastrocnemius muscles vibrates synchronously with the set initial music therapy bed mode frequency and amplitude. The initial music therapy bed mode frequency is lower than the stress relief mode frequency, and the initial music therapy bed mode amplitude is greater than the stress relief mode amplitude. After the music therapy bed mode begins, the amplitude of the hybrid exciter performs dynamic gain control in accordance with the real-time volume peak of the meditation music.

[0022] Furthermore, the method for adjusting the amplitude of the hybrid exciter of the car intelligent seat based on the user's sitting posture data under the command of the parking state healing mode, as fed back by the hybrid exciter, includes: setting comfortable pressure ranges for the scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle areas of the car intelligent seat; when the user is in the stress relief healing mode or music therapy bed mode, if the real-time pressure value of any point in the scapula, lumbar spine, sciatic nerve, or gastrocnemius muscle area is not within the corresponding comfortable pressure range, the amplitude of the hybrid exciter in the area where the real-time pressure value of the user's scapula, lumbar spine, sciatic nerve, or gastrocnemius muscle area is not within the corresponding comfortable pressure range will be increased or decreased, so that the real-time pressure value of any point in the scapula, lumbar spine, sciatic nerve, or gastrocnemius muscle area is within the corresponding comfortable pressure range.

[0023] Furthermore, when the vehicle is in a forward-moving state, the method for generating a forward-moving state healing mode instruction to control the working state of the car's intelligent seat hybrid exciter based on the current user's sitting posture data includes: when the vehicle is in a forward-moving state and the pressure on the user's sciatic nerve is continuously greater than a set threshold for a set time, the user is recommended to use the long-distance soothing mode.

[0024] Furthermore, in long-distance relaxation mode, the user's lumbar spine and sciatic nerve area are stimulated by a hybrid exciter that vibrates intermittently at a set frequency and amplitude.

[0025] Furthermore, the method for adjusting the amplitude of the hybrid exciter of the car's intelligent seat based on the current vehicle steering wheel angle, current vehicle acceleration, and user posture data fed back by the hybrid exciter of the car's intelligent seat under the instruction of the forward-moving healing mode includes: when the vehicle is in a forward-moving state and the steering wheel angle is greater than a set threshold, the hybrid exciter in the lumbar region is turned off; when the vehicle is in a forward-moving state and the vehicle acceleration value is greater than a set value, the amplitude of all hybrid exciters is reduced to the set value; when the vehicle is in a forward-moving state and the steering wheel angle is less than or equal to a set threshold, and the vehicle acceleration value is less than or equal to a set value, if the real-time pressure value at any point in the lumbar spine or sciatic nerve region of the car's intelligent seat is not within the corresponding long-distance relief pressure range, the amplitude of the hybrid exciter at the point in the lumbar spine or sciatic nerve region where the real-time pressure value is not within the corresponding long-distance relief pressure range is increased or decreased, so that the real-time pressure value at any point in the lumbar spine or sciatic nerve region is within the corresponding comfort pressure range.

[0026] Furthermore, a method for controlling a car seat with haptic music therapy function based on the system includes:

[0027] The intelligent car seat hybrid exciter acquires user posture data.

[0028] The system determines whether the vehicle is in a parked state based on its gear and speed. When the vehicle is in a parked state, it generates a parking state healing mode command based on the current backrest angle of the smart car seat, the current user's sitting posture data, and the user's physiological data. It also adjusts the amplitude of the smart car seat hybrid exciter based on the user's sitting posture data fed back by the smart car seat hybrid exciter under the parking state healing mode command.

[0029] When the vehicle is moving forward, a forward-moving healing mode command is generated based on the current user's seating posture data to control the working state of the car's intelligent seat hybrid exciter. The amplitude of the car's intelligent seat hybrid exciter is adjusted based on the current vehicle steering wheel angle, the current vehicle acceleration, and the user's seating posture data fed back by the car's intelligent seat hybrid exciter under the forward-moving healing mode command.

[0030] Furthermore, a car seat with haptic music therapy function includes a seat and also includes: a therapy decision module and a hybrid exciter disposed within the seat;

[0031] The hybrid exciter is used to acquire user posture data and also to convert healing mode commands in parking or forward states into mechanical vibration and audible sound signals.

[0032] The healing decision module is used to determine whether the vehicle is in a parked state based on the vehicle's gear and speed. When the vehicle is parked, it generates a parking state healing mode command based on the current backrest angle of the smart car seat, the current user's sitting posture data, and the user's physiological data. It also adjusts the amplitude of the smart car seat hybrid exciter based on the user's sitting posture data fed back by the smart car seat hybrid exciter under the parking state healing mode command.

[0033] When the vehicle is moving forward, a forward-moving healing mode command is generated based on the current user's seating posture data to control the working state of the car's intelligent seat hybrid exciter. The amplitude of the car's intelligent seat hybrid exciter is adjusted based on the current vehicle steering wheel angle, the current vehicle acceleration, and the user's seating posture data fed back by the car's intelligent seat hybrid exciter under the forward-moving healing mode command.

[0034] Furthermore, the arrangement of the hybrid exciter within the seat satisfies a target function relationship between the exciter position and the intensity of human perception, the expression of which is:

[0035] To maximize the human body's comprehensive perception of sound and tactile sensation, β audio (U) and β haptic (U) is the adaptive weights combined with the user feature vector U, which are 0.6 + δ u and 0.4-δ u δ u ∈[-0.1,0.1];

[0036] To minimize crosstalk between exciters, a crosstalk physical model is used. Calculate, where k is the coupling coefficient, f i For exciter-related parameters, d ij Let be the distance between exciter i and exciter j, γ be the penalty coefficient, γ∈[0.2,0.5], and d be the mechanical crosstalk hard constraint. ij ≥80+∈, ∈≥0, acoustic sensitive area constraint is Where, x i Let x be the spatial location vector of the i-th exciter. ear The location is the ear, k is the attenuation coefficient, and the tactile sensitive area is constrained to S. body,i =α·T(x i ), α·T(x i )≥T min , T(x i ) represents muscle thickness, T min Let α be the muscle thickness threshold, α be the correlation coefficient, and the neural density avoidance constraint be ||x||. i -x nerve ||≥R safe x nerve R is the location vector of the dense neural region. safe The safe distance between the exciter and the densely packed neural area;

[0037] The constraint handling rule is: if d ij If the value is less than 80, the solution is invalid. If multiple solutions satisfy the constraints, they are sorted in descending order of objective function value, and the solution with the larger objective function value is selected first.

[0038] The beneficial effects of this invention are as follows: Addressing the problems of existing music seats, such as the tendency for full-frequency vibration to cause user overload, limited expansion of therapeutic modes, and lack of intelligent dynamic adjustment capabilities, this invention deeply integrates medical targeted frequencies with a hybrid exciter system for automotive seats. Multiple sets of micro-hybrid exciters are deployed in key areas of the seat to form a vibration network targeting physiological fatigue regions. Combined with vehicle status data, real-time user pressure distribution, and physiological indicators, a multi-mode adaptive adjustment mechanism is constructed, including precise intervention for muscle and joint fatigue caused by prolonged sitting. Simultaneously, a safety control strategy is introduced to dynamically adjust vibration parameters based on driving operations, acceleration changes, and the user's physiological state, effectively avoiding vibration interference with driving safety and potential muscle fiber damage from overstimulation. This significantly alleviates deep fatigue in the shoulders, neck, lumbar spine, and gluteal muscles while improving driving comfort and promoting blood circulation and lactic acid metabolism. This invention is used to alleviate symptoms of sedentary behavior syndrome in vehicle use scenarios, providing users with a lifestyle-integrated assisted physical therapy method during commutes. Furthermore, by optimizing the time-sharing power supply of the hybrid exciter, peak power consumption is reduced, and the honeycomb aluminum substrate reduces vibration and resonance noise.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0046] Example 1

[0047] like Figure 5 As shown, a car seat control system with haptic music therapy function includes:

[0048] The intelligent car seat hybrid exciter is used to acquire user posture data and execute healing mode commands in either the parking state or the forward state.

[0049] The healing decision module is used to determine whether the vehicle is in a parked state based on the vehicle's gear and speed. When the vehicle is parked, it generates a parking state healing mode command based on the current backrest angle of the smart car seat, the current user's sitting posture data, and the user's physiological data. It also adjusts the amplitude of the smart car seat hybrid exciter based on the user's sitting posture data fed back by the smart car seat hybrid exciter under the parking state healing mode command.

[0050] When the vehicle is moving forward, a forward-moving healing mode command is generated based on the current user's seating posture data to control the working state of the car's intelligent seat hybrid exciter. The amplitude of the car's intelligent seat hybrid exciter is adjusted based on the current vehicle steering wheel angle, the current vehicle acceleration, and the user's seating posture data fed back by the car's intelligent seat hybrid exciter under the forward-moving healing mode command.

[0051] like Figure 1 As shown, the system architecture of this invention is as follows: The scene perception layer collects real-time user physiological data (such as seat pressure distribution, skin conductance response, and heart rate) and vehicle status data (such as steering angle, acceleration, and seat tilt angle). This data is then fused through the data processing center of the decision execution layer. An AI algorithm engine automatically selects the healing mode, and the underlying vibration control and music therapy modules output appropriate tactile and acoustic interventions. Simultaneously, the system integrates a safety control layer, utilizing a high-frequency real-time monitor and a dynamic rule base (such as turning off lumbar vibration during steering and reducing intensity during rapid acceleration) to ensure that all functions prioritize driving safety during operation. Users can customize these settings through the interactive interface.

[0052] Figure 2The business process diagram of this invention first involves data collection and scene perception, including physiological monitoring (lumbar spine pressure analysis and pressure level assessment) and vehicle status monitoring (driving operation recognition and seat posture detection). Then, an intelligent decision-making stage is entered, where a stress-relieving therapy mode (four-zone linkage wandering stimulation and 60-100Hz pulsating relaxation), a music therapy bed mode (60Hz vibration and 40℃ heat therapy for whole-body vibration and heating), or a long-distance relaxation mode (intermittent energy injection into the lumbar and hip areas and anti-muscle fatigue algorithm) is selected through pattern matching. Finally, a dynamic protection stage is entered, where real-time physiological monitoring (pressure, heart rate) and vehicle status tracking (steering, G-value) determine whether a rule has been triggered. If triggered, parameters are dynamically adjusted (reduction / shutdown / frequency limiting) and static, dynamic, or emergency safety strategies (intensity suppression or shutdown) are executed; otherwise, the current mode is maintained and monitoring returns.

[0053] In some technical solutions, the hybrid exciter of the car's intelligent seat is deactivated when the vehicle is in reverse gear and the speed is greater than 0. Reversing requires the driver to concentrate highly, observe the rear environment, and control the vehicle's speed and direction. The vibrations generated by the hybrid exciter may distract the driver and increase the risk of operational errors. Deactivating the hybrid exciter can prevent vibration from interfering with driving and reduce the occurrence of potential accidents.

[0054] Some technical solutions involve acquiring user posture data by installing a smart car seat hybrid exciter on the car seat base and backrest to collect pressure data on the user's scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle in real time.

[0055] Methods for obtaining user physiological data include: setting up bioelectrical sensing electrodes on the car steering wheel to collect the user's skin conductance response data and heart rate variability data in real time.

[0056] Hybrid exciters precisely identify the user's posture, pressure points, and muscle tension areas at key physiological locations on the seat (scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle), providing a data basis for fatigue localization of the user's body parts. The bioelectric electrodes on the steering wheel collect real-time data on the human body's skin conductance (reflecting emotional excitement / stress levels) and heart rate variability (reflecting autonomic nervous system activity and fatigue), physiologically quantifying the user's tension and fatigue state.

[0057] In some technical solutions, when the vehicle is parked, methods for generating parking state healing mode commands to control the operation of the vehicle's smart seat hybrid exciter based on the current backrest angle of the smart seat, the current user's sitting posture data, and the user's physiological data include:

[0058] F(P)=MAX(|Ps-Ps0| / σs,|Pl-Pl0| / σl,|Pi-Pi0| / σi,|Pc-Pc0| / σc);

[0059] F(EDA) = |EDA - EDA0| / σeda;

[0060] F(HRV) = |HRV0 - HRV| / HRV0;

[0061] When MAX(F(P),F(EDA),F(H RV))>T1, it is recommended that users use the stress relief and healing mode;

[0062] Wherein, F(P) is the maximum standardized deviation of the real-time pressure values ​​at the user's scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle from the corresponding resting baseline pressure values; F(EDA) is the standardized deviation of the user's real-time skin conductance response value from the resting baseline skin conductance response value; F(HRV) is the relative decrease ratio of the user's real-time heart rate variability value to the optimal baseline heart rate variability value; Ps is the real-time pressure value at the user's scapula; Pl is the real-time pressure value at the user's lumbar spine; Pi is the real-time pressure value at the user's sciatic nerve; Pc is the real-time pressure value at the user's gastrocnemius muscle; Ps0 is the user's baseline resting pressure value at the scapula; Pl0 is the user's baseline resting pressure value at the lumbar spine; Pi0 is the user's baseline resting pressure value at the sciatic nerve; Pc0 is the user's baseline resting pressure value at the gastrocnemius muscle; σs is the user's... Standard deviation of sitting pressure at the scapula, σl is the standard deviation of sitting pressure at the lumbar spine, σi is the standard deviation of sitting pressure at the sciatic nerve, and σc is the standard deviation of sitting pressure at the gastrocnemius muscle; EDA is the user's real-time skin conductance response value, EDA0 is the user's baseline skin conductance response value, and σeda is the standard deviation of the user's skin conductance response; HRV is the user's real-time heart rate variability value; HRV0 is the user's baseline heart rate variability value; T1 is the trigger threshold for the stress relief therapy mode, and MAX(.) is the maximum value function;

[0063] If the user selects the stress relief mode for more than the set time or the posture sensor detects that the backrest tilt angle of the car seat gyroscope is greater than the set value, it is recommended that the user select to activate the music therapy bed mode.

[0064] By introducing individual user-specific sedentary baseline values ​​(such as Ps0, EDA0, HRV0, etc.) and standard deviations (such as σs, σeda, etc.), standardized deviation calculation based on user-specific physiological characteristics is achieved, eliminating the influence of individual differences and ensuring highly targeted and suitable assessment results. User status is assessed simultaneously using parameters such as pressure distribution (F(P)), skin conductance response (F(EDA)) and heart rate variability (F(HRV)), and a maximum value function (MAX) is used for collaborative judgment, improving the reliability of user status assessment and avoiding misjudgment based on a single indicator. Standard deviation is used for normalization, triggering massage therapy recommendations when deviations significantly exceed normal fluctuations, avoiding misjudgments, while the maximum value function ensures the system can respond quickly to abnormal changes in any single indicator. Subsequently, music therapy bed modes are recommended based on usage time or backrest angle, reflecting a gradual process from basic relaxation to deep healing, ensuring a natural and smooth healing process and improving user experience.

[0065] The real-time pressure value is the real-time pressure value collected by the seat hybrid stimulus at the corresponding parts of the user (scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle); the seated pressure baseline value is obtained by calculating the arithmetic mean of the pressure data sequence generated at each part (scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle) in a relaxed state during the hybrid stimulus pressure measurement and calibration phase; the seated pressure standard deviation is obtained by calculating the standard deviation of the pressure data sequence collected by the user at each part (scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle) in a relaxed state during the hybrid stimulus pressure measurement and calibration phase, and is used to quantify the natural fluctuation range of the user's pressure under normal conditions.

[0066] In some embodiments, the hybrid exciters are arranged in a matrix on the car seat base and backrest. The analog pressure signal generated by the hybrid exciter matrix is ​​first converted into a digital signal in the range of 0-4095 by an ADC (Analog to Digital Converter). To efficiently transfer data without consuming excessive CPU resources, the system uses an SPI interface in conjunction with a DMA (Memory Access Controller). The pressure data generated by the hybrid exciters triggers DMA requests byte by byte. The DMA controller automatically moves the converted digital signal `adc_raw` to a dual buffer in memory without CPU intervention. When one buffer is full, the DMA sends a transfer completion interrupt notification to the CPU. The CPU then begins processing the data in that buffer, while the DMA switches to the other buffer to continue writing new data, achieving parallel operation of data acquisition and processing and improving the system's real-time performance. The CPU is the core control unit. Upon receiving the DMA transfer completion interrupt, the CPU begins calculating the pressure data.

[0067] In some embodiments, the vibration mode of stress relief healing has a relatively high intensity. If the user uses this vibration frequency for too long, there may be safety issues. Therefore, the user is given the option to independently set the usage duration, such as 3 - 15 minutes, before starting to use the stress relief healing mode. If the time selected by the user in the settings interface is 20 minutes, it will automatically switch to the music therapy bed mode, and the interface will provide a professional explanation to ensure the safety of the user. When the inclination angle of the gyroscope backrest of the user's car seat is greater than 150°, the user is in a relaxed state lying on the car seat. At this time, the stress relief healing mode is recommended for the user to relax and heal.

[0068] In some technical solutions, when healing the user's body in the stress relief healing mode, the hybrid exciters at the user's scapula, lumbar spine, sciatic nerve, and gastrocnemius vibrate and massage at a set frequency and amplitude of the stress relief healing mode along the set massage sequence at the scapula, lumbar spine, sciatic nerve, and gastrocnemius, with a preset time interval.

[0069] In some embodiments, the stress relief healing mode is set with a 15 - minute safety time limit. In the stress relief healing mode, the scapula, lumbar spine, sciatic nerve, and gastrocnemius of the intelligent car seat achieve four - zone linkage wandering excitation. The adjacent hybrid exciters are started at a time interval of 50 ms. The hybrid exciters vibrate at a frequency of 60 - 100 Hz and an amplitude of ±1 mm to ±2 mm, along the set massage sequence at the scapula, lumbar spine, sciatic nerve, and gastrocnemius to promote the relaxation of the meridians. The scapular area simultaneously starts graphene heating at 40 °C to dilate blood vessels and accelerate lactic acid metabolism.

[0070] Vibrations with specific healing frequencies and controlled amplitudes can accurately act on deep muscle groups and key acupoints, effectively promoting local blood circulation, accelerating the decomposition and excretion of metabolic wastes such as lactic acid, and thus quickly relieving muscle stiffness and soreness caused by long - term sitting. By setting the vibration sequence and interval time, a wave - like or wandering excitation effect is formed. This orderly stimulation can guide the gradual relaxation of the human meridians, coordinate the relaxation rhythm between different muscle groups, avoid the nerve rejection reaction that may be caused by simultaneous intense vibration, and improve the user's comfort.

[0071] In some technical solutions, at the start of the music therapy bed mode, the hybrid exciters of the intelligent car seat play meditation music. The hybrid exciters at the user's scapula, lumbar spine, sciatic nerve, and gastrocnemius vibrate synchronously at a set initial music therapy bed mode frequency and amplitude. The initial music therapy bed mode frequency is less than the stress relief healing mode frequency, and the initial music therapy bed mode amplitude is greater than the stress relief healing mode amplitude. After the start of the music therapy bed mode, the amplitude of the hybrid exciters performs dynamic gain control in配合 with the real - time volume peak of the meditation music.

[0072] By playing meditation music in sync with the activation of low-frequency, low-amplitude vibrations throughout the body, and by introducing a dynamic gain control mechanism based on real-time audio signal processing, the amplitude of the hybrid exciter is no longer fixed, but is dynamically adjusted as a function of the music sound pressure level. This allows the physical vibration of the seat to change synchronously with the user's auditory experience, enhancing the user's immersion and experience.

[0073] In some embodiments, in the music therapy bed mode, a hybrid exciter at the user's scapula, lumbar spine, sciatic nerve, and gastrocnemius muscles provides a vibration massage at a frequency of 60Hz and an amplitude of ±3mm to ±4mm. Simultaneously, 40℃ heat therapy is activated at the user's scapula, lumbar spine, sciatic nerve, and gastrocnemius muscles. When combined with the dynamic gain control of the corresponding meditation music, the vibration intensity is adjusted according to the peak volume of the meditation. For every 6dB increase in the peak volume of the meditation, the amplitude increases by 0.1G (G is the acceleration due to gravity). A 30-minute time limit is set to reach a safe limit. After reaching the safe limit, the hybrid exciter stops vibrating and monitors and compares the user's physiological values ​​before and after the massage, quantitatively displaying the effect of the hybrid exciter massage on the user's muscle relaxation.

[0074] In some technical solutions, the method of adjusting the amplitude of the hybrid exciter of the car smart seat based on the user's sitting posture data under the command of the parking state healing mode, as fed back by the hybrid exciter, includes: setting comfortable pressure ranges for the scapula, lumbar spine, sciatic nerve, and gastrocnemius muscle areas of the car smart seat; when the user is in the stress relief healing mode or music therapy bed mode, if the real-time pressure value of any part of the scapula, lumbar spine, sciatic nerve, or gastrocnemius muscle area is not within the corresponding comfortable pressure range, the amplitude of the hybrid exciter in the area of ​​the user's scapula, lumbar spine, sciatic nerve, or gastrocnemius muscle area where the real-time pressure value is not within the corresponding comfortable pressure range is increased or decreased, so that the real-time pressure value of any part of the scapula, lumbar spine, sciatic nerve, or gastrocnemius muscle area is within the corresponding comfortable pressure range.

[0075] By monitoring the actual pressure values ​​of the user's scapula, lumbar spine, sciatic nerve, and gastrocnemius muscles in real time through a hybrid stimulus, once the real-time pressure of any part deviates from its comfort range (for example, excessive pressure may mean excessive muscle tension or improper posture, while excessive pressure may indicate insufficient contact), the system will automatically adjust the amplitude of the hybrid stimulus for that specific part. This will either increase the amplitude of the hybrid stimulus to enhance the penetration of the stimulation, or decrease the amplitude of the hybrid stimulus to avoid excessive compression of the muscles. This avoids problems such as pressure concentration or insufficient stimulation caused by differences in user body shape, sitting habits, or body movement, effectively preventing muscle compression damage or poor blood circulation that may be caused by improper pressure over a long period of time. It provides a comfortable, safe, and efficient personalized intelligent healing experience for different users in different states.

[0076] In some embodiments, when the monitored lumbar spine pressure value is greater than 30 kPa, the amplitude of the hybrid exciter is reduced to ±2 mm to prevent overload stimulation from causing muscle fiber damage. When the lumbar spine pressure value is less than 20 kPa, the amplitude of the hybrid exciter is increased to ±5 mm.

[0077] In some technical solutions, when the vehicle is in a forward-moving state, the method for generating a forward-moving state healing mode instruction based on the current user's sitting posture data includes: when the vehicle is in a forward-moving state and the pressure on the user's sciatic nerve is continuously greater than a set threshold for a set time, the user is recommended to use the long-distance relief mode.

[0078] By continuously monitoring pressure at the sciatic nerve, early physiological signs such as stiff gluteal muscles and poor blood circulation caused by prolonged sitting can be identified. Combined with the premise that the vehicle is in motion, this ensures that the long-distance relaxation mode operates only while the vehicle is in driving mode, avoiding accidental triggering when parking or reversing. Before the user experiences noticeable discomfort, the system proactively recommends the long-distance relaxation mode based on the user's current posture data, thus proactively preventing early fatigue accumulation, effectively delaying the onset of lumbar muscle strain, and improving blood circulation in the gluteal muscles.

[0079] In some embodiments, if the ischial pressure remains greater than 30 kPa for up to 45 minutes while the vehicle is traveling in D gear, it is recommended that the user use the long-distance relaxation mode.

[0080] In some technical solutions, during long-distance relaxation mode, a hybrid exciter for the user's lumbar spine and sciatic nerve area vibrates intermittently at a set frequency and amplitude.

[0081] In some embodiments, during long-distance relaxation mode, the seat hybrid exciter intermittently injects energy into the user's lumbar spine and sciatic nerve area, using a 40Hz square wave (2s on / 2s off) with an amplitude of ±2mm to ±3.5mm for vibration massage. This avoids muscle fatigue, prevents lumbar muscle strain, and improves blood circulation in the gluteal muscles. The amplitude of the hybrid exciter is dynamically adjusted according to the pressure distribution. When the pressure in the lumbar spine area exceeds 30kPa, the amplitude is reduced to ±2mm to prevent overload. Furthermore, the single-use time should be less than 45 minutes, and the user is notified that the service has ended after the safe time limit is reached.

[0082] In some technical solutions, the method of adjusting the amplitude of the hybrid exciter of the car's intelligent seat based on the current vehicle steering wheel angle, current vehicle acceleration, and user posture data fed back by the hybrid exciter of the car's intelligent seat under the instruction of the forward-moving healing mode includes: when the vehicle is in a forward-moving state and the steering wheel angle is greater than a set threshold, the hybrid exciter in the lumbar region is turned off; when the vehicle is in a forward-moving state and the vehicle acceleration value is greater than a set value, the amplitude of all hybrid exciters is reduced to the set value; when the vehicle is in a forward-moving state and the steering wheel angle is less than or equal to a set threshold, and the vehicle acceleration value is less than or equal to a set value, if the real-time pressure value at any point in the lumbar spine or sciatic nerve region of the car's intelligent seat is not within the corresponding long-distance relief pressure range, the amplitude of the hybrid exciter at the part of the lumbar spine or sciatic nerve region where the real-time pressure value is not within the corresponding long-distance relief pressure range is increased or decreased, so that the real-time pressure value at any point in the lumbar spine or sciatic nerve region is within the corresponding comfort pressure range.

[0083] When the car is moving forward, the steering wheel angle is primarily used to determine emergency avoidance scenarios (sharp and large steering wheel turns) and frequent lane changes (continuous steering wheel turns). In these scenarios, users have extremely high demands for driving safety, and functions that affect the user's physical sensations should be disabled to prevent interference with driving. Simultaneously, when the car accelerates excessively, the vehicle is in a state of rapid acceleration, and users have extremely high driving safety requirements. Excessive vibration massage can interfere with the user's driving operation; reducing the amplitude of the hybrid exciter can prevent accidents. In some implementations, the steering wheel angle threshold can be, but is not limited to, 15°, and when the vehicle acceleration value exceeds 0.4g, the vibration amplitude of all hybrid exciters is reduced to 20%.

[0084] Example 2

[0085] A car seat control method with haptic music therapy function based on the system of claim 1, comprising:

[0086] The intelligent car seat hybrid exciter acquires user posture data.

[0087] The system determines whether the vehicle is in a parked state based on its gear and speed. When the vehicle is in a parked state, it generates a parking state healing mode command based on the current backrest angle of the smart car seat, the current user's sitting posture data, and the user's physiological data. It also adjusts the amplitude of the smart car seat hybrid exciter based on the user's sitting posture data fed back by the smart car seat hybrid exciter under the parking state healing mode command.

[0088] When the vehicle is moving forward, a forward-moving healing mode command is generated based on the current user's seating posture data to control the working state of the car's intelligent seat hybrid exciter. The amplitude of the car's intelligent seat hybrid exciter is adjusted based on the current vehicle steering wheel angle, the current vehicle acceleration, and the user's seating posture data fed back by the car's intelligent seat hybrid exciter under the forward-moving healing mode command.

[0089] Example 3

[0090] In some technical solutions, a car seat with haptic music therapy function includes a seat, characterized in that it further includes: a therapy decision module and a hybrid exciter 2 arranged in the seat;

[0091] Hybrid exciter 2 is used to acquire user sitting posture data and also to convert the parking state healing mode command or the forward state healing mode command into mechanical vibration and audible sound signals.

[0092] The healing decision module is used to determine whether the vehicle is in a parked state based on the vehicle's gear and speed. When the vehicle is in a parked state, it generates a parking state healing mode command based on the current car smart seat backrest tilt angle, the current user sitting posture data, and the user's physiological data. It also adjusts the amplitude of the car smart seat hybrid exciter 2 based on the user sitting posture data fed back by the car smart seat hybrid exciter 2 under the parking state healing mode command.

[0093] When the vehicle is moving forward, a forward state healing mode command is generated based on the current user's seating posture data to control the working state of the car intelligent seat hybrid exciter 2. The amplitude of the car intelligent seat hybrid exciter 2 is adjusted based on the current vehicle steering wheel angle, the current vehicle acceleration, and the user's seating posture data fed back by the car intelligent seat hybrid exciter 2 under the forward state healing mode command.

[0094] Hybrid exciter (or oscillator, a single hardware component that converts electrical signals into both mechanical vibrations and audible sound signals, supporting full-range vibration audio):

[0095] Structural Composition: As the core component of the "acoustic-vibration integration," the hybrid exciter adopts an integrated design, mainly consisting of a dual-mode drive control unit, a composite vibration assembly (including a high-frequency sound-generating diaphragm and a low-frequency inertial vibration block), a shared mounting bracket, and an acoustic-vibration isolation layer, as described in patent CN 119676619 A. In the composite vibration assembly, the high-frequency sound-generating diaphragm and the haptic vibration unit are coupled through elastic connectors. The mounting bracket is adapted to a position of 50%-60% of the seat back height (corresponding to the sensory sensitive areas of the human shoulder blade and auricle), with the installation depth controlled at 20-30mm to balance sound generation efficiency and vibration transmission effect. The acoustic-vibration isolation layer uses damping material to avoid mutual interference between high-frequency sound generation and low-frequency vibration.

[0096] Function: To achieve "synchronous integration of audible sound output and mechanical vibration feedback", the core functions include: while outputting audible sound signals above 50Hz, simultaneously generating mechanical vibrations from 0.1Hz to 500Hz; adapting corresponding gain-phase curves for different scenarios such as music and film to ensure consistency in intensity and phase between acoustic and vibration signals; and maximizing the overall perceived intensity of sound vibration by optimizing the installation position (e.g., distance from the auricle ≤150mm, distance from the scapula ≤40mm).

[0097] Principle: The system integrates a dual conversion mechanism of airborne sound excitation and haptic excitation, while achieving coordinated output through cross-band calibration. Signal Distribution and Driving: After receiving the full-frequency signal processed by frequency division, the dual-mode drive unit directs the high-frequency component (>50Hz) to the sound-generating diaphragm drive circuit and the low-frequency component (0.1Hz–500Hz) to the vibration unit drive circuit. Dual-mode Energy Conversion: The high-frequency signal drives the lightweight diaphragm to vibrate and generate airborne sound, while the low-frequency signal drives the inertial mass block to vibrate and generate mechanical vibration. The two are physically coupled through a composite vibration component. Synchronous Calibration: For the overlapping frequency band of 50Hz–500Hz, the time delay difference between the sound and vibration signals is calculated using a cross-correlation algorithm. The vibration signal is then time-domain shifted to control the phase difference within a set error range. Simultaneously, through weighted conversion of the coupling coefficient, the mutual contribution components of the sound and vibration signals are superimposed, ultimately achieving a synchronized output effect integrating sound and vibration.

[0098] The car seat with haptic music therapy function also includes an air sound exciter 1 arranged inside the seat.

[0099] Airborne sound exciter (converts electrical signals into audible sound signals, which are then transmitted to the human ear):

[0100] Structural Composition: Based on the acoustic-vibration interaction scenario of automotive cabins and the general technical architecture of exciters, airborne acoustic exciters typically consist of a signal interface module, an electromagnetic drive unit, lightweight vibration-generating components (such as conical or planar diaphragms), and an acoustic cavity support structure. Its core drive unit includes a permanent magnet, a voice coil, and an elastic suspension system. The diaphragm is often made of lightweight rigid materials (such as paper composite films or metal films). The overall structure is adaptable to embedded installation requirements in seat headrests or cabin interiors, with a compact size and vibration-resistant design.

[0101] Function: As a dedicated output device for acoustic signals, its core function is to convert the high-frequency electrical signals (typically audible frequencies above 50Hz) transmitted by the power drive module into clear and uniform airborne sound signals, providing users with an immersive audio experience. In automotive seat systems, it needs to accurately reproduce audible sound information such as music, movie sound effects, and navigation voice, and must match the characteristics of the cabin acoustic environment to avoid sound field distortion or crosstalk.

[0102] Principle: Following the conversion logic of "electric-magnetic-mechanical-acoustic energy," it first receives a format-adapted and amplified digital acoustic drive signal through a signal interface. The voice coil within the drive unit vibrates in the magnetic field formed by the permanent magnet, according to the frequency and amplitude of the electrical signal. The vibration of the voice coil drives the connected lightweight diaphragm to vibrate synchronously. The diaphragm compresses and disturbs the surrounding air medium, forming compression and sparsity waves, thus generating an audible sound signal that can be perceived by the human ear. Similar to the principle of traditional loudspeakers, its diaphragm design and installation method are better suited to the space constraints of a car cabin. The uniformity of sound field coverage can be improved by optimizing the diaphragm curvature and acoustic cavity parameters.

[0103] In some technical solutions, the arrangement of the airborne acoustic exciter 1 and the hybrid exciter 2 within the seat satisfies a target function relationship between the exciter position and the human body's perceived intensity. The target function expression for the exciter position and the human body's perceived intensity is as follows:

[0104]

[0105] To maximize the human body's comprehensive perception of sound and tactile sensation, β audio (U) and β haptic (U) is the adaptive weights combined with the user feature vector U, which are 0.6 + δ u and 0.4-δ u δ u ∈[-0.1,0.1];

[0106] To minimize crosstalk between exciters, a crosstalk physical model is used. Calculate, where k is the coupling coefficient, f iFor exciter-related parameters, d ij Let be the distance between exciter i and exciter j, γ be the penalty coefficient, γ∈[0.2,0.5], and d be the mechanical crosstalk hard constraint. ij ≥80+∈, ∈≥0, acoustic sensitive area constraint is Where, x i Let x be the spatial location vector of the i-th exciter. ear The location is the ear, k is the attenuation coefficient, and the tactile sensitive area is constrained to S. body,i =α·T(x i ), α·T(x i )≥T min , T(x i ) represents muscle thickness, T min Let α be the muscle thickness threshold, α be the correlation coefficient, and the neural density avoidance constraint be ||x||. i -x nerve ||≥R safe x nerve R is the location vector of the dense neural region. safe The safe distance between the exciter and the densely packed neural area;

[0107] The constraint handling rule is: if d ij If the value is less than 80, the solution is invalid. If multiple solutions satisfy the constraints, they are sorted in descending order of objective function value, and the solution with the larger objective function value is selected first.

[0108] The minimum setup distance and maximum number of actuators can be obtained from the above formulas. The actuators can then be arranged and verified according to actual needs.

[0109] like Figure 3As shown in Figure 4, in some embodiments, there are multiple hybrid exciters 2, which are arranged on the backrest or other positions, closely integrated with the structure of the vehicle seat, requiring no additional space and reducing space costs. Furthermore, since they simultaneously possess sound and vibration functions, compared to installing separate airborne sound exciters and haptic exciters, the number of components is reduced, thus lowering procurement costs and installation complexity to some extent. In terms of effect, their placement above the backrest, at a suitable distance from the ear, achieves a high sound pressure level while simultaneously stimulating the user through both auditory and tactile stimulation by emitting sound to the auricle and providing low-frequency vibrations to the shoulder blades, greatly enhancing the user's sensory experience. In multimedia entertainment and virtual reality applications, this creates a richer and more immersive atmosphere. The placement at a specific angle and distance from the tragus and shoulder blades is an ergonomically optimized design, allowing sound and vibration to be better perceived by the human body, improving the user experience. The hybrid exciter 2 is also positioned under the backrest, on the seat cushion, thighs, and leg rests. These locations are mostly standard structural areas of the car seats themselves, eliminating the need for redesigning complex fixing structures or reserving special spaces for the exciter installation, thus reducing design and manufacturing costs. Furthermore, the relatively open spaces in these locations facilitate mass installation, improving installation efficiency and further reducing costs. In terms of effects, placement under and on the backrest provides low-frequency vibration feedback to the user's back, allowing for a more realistic experience of low-frequency impacts in sounds such as explosions and engine roars, especially during movie watching or gaming. Placement on the seat cushion, thighs, and leg rests enhances the user's perception of the vehicle's movement (such as bumps and acceleration) through low-frequency vibrations, improving immersion and making the experience more realistic.

[0110] For the airborne sound exciter 1: Placing the airborne sound exciter 1 on the sides of the headrest and seat cushion eliminates the need for large-scale modifications to the vehicle's interior structure, reducing adaptation difficulty and modification costs. Furthermore, its relatively easy-to-access location facilitates convenient maintenance and component replacement, saving labor costs. In terms of performance, placement on the headrest, closer to the ears, allows for higher sound pressure levels at lower power, delivering sound more efficiently and improving clarity and sound quality. Placement on the side of the seat cushion provides sound coverage for the lower body, resulting in a more uniform sound field within the vehicle and enhancing the overall listening experience.
