Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle control technology, specifically to a vehicle control method, device, and vehicle. Background Technology
[0002] With the widespread use of automobiles, vehicles have become mobile rest spaces for drivers and passengers. When parked, occupants can activate the vehicle's rest mode for a short nap. To prevent breathing obstruction caused by improper sleeping posture, the current solutions primarily rely on a Driver Monitoring System (DMS) to detect the sleep status of drivers and passengers. When the monitoring data meets the alert criteria, the system plays a posture reminder voice prompt to prompt the driver or passenger to adjust their sleeping position. However, when the driver or passenger is in a lying position, the DMS has a blind spot, leading to inaccurate detection results. Summary of the Invention
[0003] In view of the above problems, embodiments of the present invention provide a vehicle control method, device and vehicle to solve the problem of inaccurate detection results when drivers and passengers are resting in the prior art.
[0004] According to one aspect of the present invention, a vehicle control method is provided, the method comprising: Based on cabin audio collected by the vehicle's microphone, it can identify whether there are any abnormal breathing events. If the respiratory abnormality event exists, determine the vehicle control parameters based on the abnormal state corresponding to the respiratory abnormality event; The vehicle is controlled to perform rest and adjustment actions based on the vehicle control parameters. The higher the level of the abnormal state, the more obvious the user in the cabin will perceive the rest and adjustment actions.
[0005] According to another aspect of the present invention, a vehicle control device is provided, comprising: The event recognition module is used to identify whether there is an abnormal breathing event based on the cabin audio collected by the vehicle microphone; The parameter determination module is used to determine vehicle control parameters based on the abnormal state corresponding to the respiratory abnormality event when the respiratory abnormality event exists. The vehicle adjustment module is used to control the vehicle to perform rest adjustment actions based on the vehicle control parameters, wherein the higher the level of the abnormal state, the more obvious the user in the cabin will perceive the rest adjustment actions.
[0006] According to another aspect of the present invention, an automobile is provided, comprising: a processor, a memory, a communication interface, and a communication bus, wherein the processor, the memory, and the communication interface communicate with each other via the communication bus; The memory is used to store at least one executable instruction that causes the processor to perform the operation of the vehicle control method as described above.
[0007] According to another aspect of the present invention, a computer-readable storage medium is provided, the storage medium storing at least one executable instruction that causes a vehicle / car privacy protection device to perform the operation of the vehicle control method as described above.
[0008] When an abnormal breathing event is detected, this invention determines vehicle control parameters based on the abnormal state corresponding to the event, and then controls the vehicle to perform rest and adjustment actions based on these parameters. The higher the level of the abnormal state, the more noticeable the rest and adjustment actions become to the users inside the cabin. This proactively improves the cabin environment or rest posture that caused the breathing abnormality through targeted vehicle adjustments, achieving proactive intervention and effective mitigation of the abnormal breathing state without relying on manual operation by the resting personnel. Furthermore, by using gradient-based perception and adjustment adapted to the abnormal state, it avoids the drawbacks of insufficient or excessive intervention associated with fixed-intensity adjustments. While ensuring the effectiveness of respiratory abnormality intervention, it also fully considers the resting experience of passengers inside the vehicle, achieving intelligent and highly adaptable proactive protection for the respiratory health of passengers resting inside the vehicle.
[0009] The above description is merely an overview of the technical solutions of the embodiments of the present invention. In order to better understand the technical means of the embodiments of the present invention and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of the present invention more apparent and understandable, specific embodiments of the present invention are described below. Attached Figure Description
[0010] The accompanying drawings are for illustrative purposes only and are not intended to limit the invention. Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings: Figure 1 A flowchart illustrating a first embodiment of the vehicle control method provided by the present invention is shown. Figure 2 An exemplary flowchart of the vehicle control method provided by the present invention is shown; Figure 3 A schematic diagram of the structure of a first embodiment of the device provided by the present invention is shown; Figure 4 A structural schematic diagram of an embodiment of the vehicle provided by the present invention is shown. Detailed Implementation
[0011] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.
[0012] Firstly, Figure 1 A flowchart of a first embodiment of the vehicle privacy protection method of the present invention is shown. This method is executed by a vehicle or a cloud platform accessed by the vehicle. The following description uses a vehicle as an example. Figure 1 As shown, the method includes the following steps: Step S10: Based on the cabin audio collected by the vehicle microphone, identify whether there is an abnormal breathing event.
[0013] Current methods of monitoring occupants using DMS cameras are prone to blind spots in parked rest scenarios due to factors such as reclining posture, low lighting, and facial obstruction, making it difficult to reliably identify breathing status. When a driver is semi-reclined in the car, the angle of the seat back can cause the head to droop due to lack of support, leading to the chin pressing against the chest, or the tongue and soft tissues to fall backward due to gravity due to excessive backward tilting. Both of these situations can cause physical narrowing of the airway, leading to snoring or even sleep apnea.
[0014] Therefore, this embodiment uses an in-vehicle microphone to collect audio for abnormal breathing identification, avoiding the inherent limitations of visual monitoring and achieving full-scene, contactless monitoring of breathing status, providing accurate triggering basis for subsequent adjustment actions. The in-vehicle microphone is a microphone array built into the vehicle for collecting sound signals within the cabin. This microphone can be placed in the seat headrest area, on the indicator light directly opposite the seat, or in other locations close to the user's breathing patterns to ensure clear capture of characteristic audio sounds such as breathing sounds and snoring. Cabin audio refers to the full-band sound signal collected by the in-vehicle microphone within the cabin, including the user's breathing sounds, snoring, and ambient noise. Abnormal breathing events refer to physiological events that deviate from the normal, stable breathing state during sleep, including snoring, obstructed breathing, shallow and slow breathing, and intermittent breathing—abnormal breathing behaviors that can be identified through audio characteristics.
[0015] As an optional implementation, when the user stops the vehicle and leans back to rest in the seat, the vehicle cabin domain controller drives the onboard microphone to continuously collect full-band audio signals in the cabin at a preset sampling rate. Then, the collected cabin audio undergoes noise reduction preprocessing and amplification processing of the human voice audio signal in the cabin to effectively separate / extract breathing sound segments and improve the accuracy of abnormal breathing event identification. Next, temporal features are extracted from the preprocessed audio signal. Finally, the extracted temporal feature parameters are compared with a preset normal breathing feature threshold range. If the feature parameters exceed the threshold range, an abnormal breathing event is determined to exist. For example, if continuous, rhythmic low-frequency, high-energy sounds are detected (exceeding the set decibel threshold), it is determined to be a snoring abnormal breathing event; if the snoring suddenly stops, resulting in a long period of background silence (e.g., >10 seconds), followed by a high-amplitude gasping sound, it is determined to be a sleep apnea abnormal breathing event.
[0016] As an alternative implementation, in addition to preprocessing the cabin audio, the location of the user inside the cabin is located based on the cabin audio, and then interference sources from other locations are eliminated to improve the accuracy of respiratory abnormality event recognition. Specifically, the vehicle control system drives the onboard microphone array to acquire omnidirectional audio signals from the cabin in a multi-channel synchronous acquisition mode. Then, the location of the user inside the cabin is located by the direction of the sound source. Next, the sound from the driver's headrest direction is amplified, while environmental noise from the air conditioning vents or outside the windows is suppressed, improving the acquisition accuracy of the cabin audio. Subsequently, the audio processing unit performs beamforming and spectral feature comparison on the multi-channel audio signals. A fast Fourier transform is used to convert the time-domain audio signal into frequency-domain power spectrum data, separating the breathing-related frequency band signals and filtering out interference noise in non-breathing frequency bands. Then, frequency-domain features such as Mel-frequency cepstral coefficients, spectral centroid, and spectral bandwidth are extracted from the frequency-domain power spectrum data. The extracted frequency-domain feature parameters are compared with preset parameters to determine whether a respiratory abnormality event exists and the type of respiratory abnormality event. In addition, it can be input into a pre-trained lightweight respiratory abnormality recognition model, and the model will infer and output the classification result of the respiratory state. If the classification result is an abnormal breathing category, it is determined that there is a respiratory abnormality event.
[0017] Specifically, when a user stops the vehicle and reclines in their seat to rest, the system needs to acquire vehicle status information to determine if the vehicle meets the preset resting conditions. This includes whether the vehicle is stopped, whether the user has activated rest mode, and whether the seat is in a large reclining position. Then, if the status information meets the preset resting conditions, the system identifies the target seat in the cabin with a backrest angle greater than the preset backrest angle—the seat where the user is currently reclining. The system then controls the onboard microphone associated with the target seat to collect cabin audio. In detail, the car detects and verifies whether the vehicle is in rest mode via a bus, including whether the vehicle is in park (P), whether the vehicle speed is 0, and whether the user has activated "rest mode" or the seat is in a large reclining position. This ensures that the monitoring function is activated only when safe resting conditions are met, avoiding the safety risk of accidental function triggering while the vehicle is in motion.
[0018] For example, when the vehicle is in parked rest mode, the in-vehicle microphone continuously collects cabin audio. When a person snoring due to improper sleeping posture, the system determines that an abnormal breathing event has occurred by detecting a sudden increase in audio amplitude and a disruption in the breathing cycle exceeding a threshold in the time domain. Alternatively, the system can extract the frequency band features corresponding to the snoring sound and classify it as a snoring abnormal event through model inference, thus completing the identification and determination of the abnormal breathing event.
[0019] Step S20: If a respiratory abnormality event exists, determine the vehicle control parameters based on the abnormal state corresponding to the respiratory abnormality event.
[0020] In this embodiment, "abnormal state" refers to the specific manifestation type and degree of deviation from normal breathing state of an abnormal breathing event, including parameters that characterize the significance of the abnormality, such as the category, duration, and magnitude of characteristic deviation of the abnormal event. Vehicle control parameters refer to quantifiable command parameters used to control the operating state of relevant actuators within the vehicle cabin, including control command sets that can be directly issued to the corresponding actuators, such as seat adjustment parameters, air conditioning operation parameters, ambient lighting control parameters, and vibration motor drive parameters. Currently, fixed reminder or adjustment strategies are often used for breathing abnormalities, which cannot adapt to different degrees of abnormal breathing states and are prone to under-adjustment or over-adjustment. This embodiment matches the identified abnormal state with corresponding control parameters; that is, different abnormal states correspond to different vehicle control parameters, achieving precise adaptation between adjustment actions and abnormal states, and providing accurate execution basis for subsequent adjustment actions.
[0021] As an optional implementation, when a respiratory abnormality event is detected, the vehicle control system obtains the abnormal state data corresponding to the event from the audio processing unit, including the abnormality type, characteristic deviation magnitude, and duration. The abnormal state data is then classified into different levels of significance based on the characteristic deviation magnitude and duration. Different levels of significance require different intensity of adjustment actions, thus transforming continuous abnormal states into matchable discrete levels and simplifying the parameter matching logic. Finally, a pre-stored abnormal state-control parameter mapping table is invoked, and vehicle control parameters are quickly matched using the pre-defined vehicle control parameters corresponding to different abnormality significance levels in the mapping table. Besides matching through the mapping table, matching can also be performed using functions, algorithms, etc.
[0022] For example, the abnormal state data corresponding to the abnormal breathing event is as follows: the abnormal type is snoring, the feature deviation amplitude is 0.09V, the peak audio amplitude during snoring reaches 0.5V, deviating from the upper limit of the normal threshold by 0.2V, and the duration is 8s, exceeding the threshold. At this time, the vehicle system classifies the above abnormal state data into levels. The preset level classification rules are: feature deviation amplitude < 0.1V and duration 5~10s is low significance level, feature deviation amplitude 0.1~0.3V and duration 10~20s is medium significance level, and feature deviation amplitude > 0.3V and duration > 20s is high significance level. Combining the current abnormal state data (deviation amplitude 0.2V, duration 12s), this abnormal state is classified as medium significance level. Subsequently, the vehicle system calls the abnormal state-control parameter mapping table pre-stored in the vehicle storage unit, where the vehicle control parameters corresponding to the low significance level are: seat back adjustment parameters (recline 3°, adjustment rate 2° / s). Based on this, the mapping table directly matches and retrieves the control parameters corresponding to the low significance level, quickly determining the vehicle control parameters and providing clear and executable instructions for subsequent rest adjustment actions. It is understandable that poor air circulation, reduced oxygen concentration, and carbon dioxide accumulation in the cabin will exacerbate breathing difficulties and snoring. Therefore, the more significant the abnormal state, the more devices need to perform control actions, i.e., the more types of vehicle control parameters are required, such as one or more parameters from seat adjustment, air conditioning vent adjustment, and seat vibration motor drive parameters. The same applies when the abnormal state is breathing obstruction.
[0023] As an alternative implementation, when a respiratory abnormality event is determined to exist, dynamic change data of the abnormal state corresponding to the respiratory abnormality event can be acquired, including real-time characteristic deviation magnitude, abnormal duration, and abnormal state change trend. Then, using normal respiratory characteristic parameters as target values and the characteristic deviation value of the current abnormal state as the control deviation, this is input into a preset fuzzy PID controller. Based on the deviation and the rate of change of deviation, the proportional, integral, and derivative coefficients are adaptively adjusted to achieve dynamic and adaptive calculation of the control parameters, adapting to the real-time changes of the abnormal state.
[0024] Understandably, in the absence of respiratory abnormalities, the vehicle's microphones continuously collect cabin audio until the user wakes up.
[0025] Step S30: Control the vehicle to perform a rest adjustment action based on the vehicle control parameters.
[0026] The higher the level of the abnormal state, the more obvious the users' perception of rest and adjustment actions will be.
[0027] In this embodiment, when controlling the vehicle to perform rest and adjustment actions based on vehicle control parameters, corresponding control actions can be executed through one or more target actuators. The higher the level of the abnormal state, the more target actuators are involved. The level of the abnormal state can be divided according to the severity of the respiratory abnormality event, for example, into three levels: mild, moderate, and severe. When the abnormal state level is mild, the seat can be slightly adjusted, such as tilting the seat back at a certain angle. When the abnormal state level is moderate, the air conditioning can be switched to external circulation mode and the airflow appropriately increased to increase the supply of fresh air in the cabin and improve oxygen concentration. When the abnormal state level is severe, more target actuators need to be activated. In addition to the air conditioning and seat adjustments, the seat vibration motor can be controlled to vibrate slightly at a certain frequency and intensity. Simultaneously, the brightness of the interior lights can be adjusted to create a more suitable resting environment, ensuring that the user can have a good resting experience in the vehicle cabin without waking them.
[0028] Rest and adjustment actions refer to the vehicle's control operations on actuators within the cabin that improve the breathing state and enhance the comfort of resting occupants based on control parameters. These actions include, at a minimum, adjustments such as seat posture adjustment, air conditioning vent adjustment, ambient lighting brightness adjustment, and seat vibration motor activation—actions that do not wake the user. Perceived intensity refers to the subjective degree to which the user in the cabin experiences the rest and adjustment actions performed by the vehicle. It is positively correlated with the adjustment amplitude, rate of change, and frequency of action. The more significant the user's abnormal breathing state and the greater the adjustment amplitude of the rest and adjustment action, the more obvious the user's perception of that action will be. Furthermore, this perceived intensity is always controlled within a range insufficient to wake the resting user.
[0029] As an optional implementation, the vehicle system analyzes vehicle control parameters, determines the target actuator corresponding to those parameters, and then executes the corresponding control action based on the target actuator. For example, if the target actuator is the adjustment motor of the driver's seat backrest, adjustments are made based on the motor's control parameters, such as adjustment range and adjustment rate, thereby changing the user's sleeping posture or neck pressure angle to eliminate physical obstruction caused by chin pressing on chest or tongue falling back, improving airway patency, and alleviating abnormal breathing conditions. During this process, the vehicle system sends control commands to the cabin domain controller, which drives the seat backrest adjustment motor to perform backrest angle adjustment actions according to the adjustment range and adjustment rate corresponding to the control parameters. Furthermore, when the target actuator is the air conditioner vent control module, the airflow or direction can be adjusted via the vent control module. This allows for short-term adjustments to the airflow or changes the direction of the air vents to directly blow on the face, using hot and cold stimuli to induce muscle contraction, triggering micro-awakening, increasing throat muscle tension, and forcing the body to resume spontaneous breathing. During the adjustment process, the vehicle system checks the matching relationship between the adjustment action and the abnormal state in real time. When the degree of abnormal state increases significantly, the adjustment amplitude or adjustment rate is increased simultaneously. When the degree of abnormal state decreases significantly, the adjustment amplitude or adjustment rate is decreased simultaneously. When the abnormal breathing event is detected to have disappeared, it indicates that the adjustment action has achieved the expected effect. The system then issues a stop adjustment command, locks the current angle of the seat back, and maintains the user's resting state.
[0030] As an alternative implementation, besides controlling a single actuator to perform the rest adjustment action, when vehicle control parameters correspond to multiple sets of actuators, multiple sets of actuators can be driven simultaneously for adjustment. For example, the vehicle system analyzes the vehicle control parameters and determines the multiple sets of actuators corresponding to those parameters, including the seat back adjustment motor, the air conditioning vent control module, the ambient lighting control module, and the corresponding hierarchical control parameters for each device, and then drives these devices synchronously. Specifically, after detecting that the abnormal breathing event has completely disappeared, each actuator can be controlled to maintain its current adjustment state or return to a pre-set operating state.
[0031] As another optional implementation, when vehicle control parameters correspond to multiple sets of actuators, in addition to simultaneously driving these devices to perform rest and adjustment actions based on the vehicle control parameters, they can also be driven in stages according to the severity of the abnormal state. This achieves graded and coordinated gradient adjustment, thereby improving the abnormal breathing state from multiple dimensions such as sleeping posture adjustment and respiratory environment optimization based on the coordinated adjustment of multiple actuators. This enhances the effectiveness of respiratory abnormality intervention without waking the user, allowing the user to achieve imperceptible rest adjustment without wearing any sensors. Specifically, when the severity of the abnormal state is low, only the air conditioning vent control module can be driven to perform a small-amplitude airflow adjustment. When the severity of the abnormal state is moderate, the seat back adjustment motor and the air conditioning vent control module are driven simultaneously to perform a moderate-amplitude adjustment. When the severity of the abnormal state is high, the seat back adjustment motor, the air conditioning vent control module, and the ambient light control module are driven simultaneously to perform corresponding-amplitude adjustments. The principle is that different numbers and amplitudes of actuators are adjusted to achieve graded and coordinated gradient adjustment. During the adjustment process, the system can receive real-time updates on abnormal states from the audio processing module and dynamically adjust the number of actuators involved in the adjustment and the adjustment range of each actuator. When the severity of the abnormal state increases, the number of actuators involved in the adjustment is increased or the adjustment range is increased; when the severity of the abnormal state decreases, the number of actuators involved in the adjustment is decreased or the adjustment range is decreased. After the abnormal breathing event is detected to have completely disappeared, the vehicle controller controls each actuator to maintain the current adjustment state or restores it to the initial state before adjustment at a preset slow rate, maximizing the user's rest and ensuring a good user experience.
[0032] It is understandable that the perceived level of the rest adjustment action in the above embodiments is lower than the awakening threshold of the user in the cabin, that is, improving the user's breathing state during rest in a non-perceptible manner. However, current interventions for breathing abnormalities are mostly fixed-intensity warnings or seat adjustments, which cannot balance the effectiveness of the intervention with the user's rest experience, and are prone to ineffective intervention or waking the user. This embodiment executes an adapted rest adjustment action based on determined control parameters, and matches a gradient adjustment logic that is more pronounced in abnormal states and more noticeable to the user, effectively improving the abnormal breathing state while maximizing the user's rest experience. Compared to rest monitoring methods based on DSM (Driver State Monitoring) systems, this embodiment better protects user privacy. Traditional DSM systems typically rely on image acquisition devices such as cameras to capture and analyze the user's facial expressions and body movements in real time. This process inevitably acquires sensitive privacy information such as the user's facial features and posture, posing a risk of privacy leakage. The vehicle control method in this embodiment, when recognizing abnormal breathing events and subsequently controlling the vehicle, does not require collecting user image information through a camera. It directly controls the vehicle based on the results of the abnormal breathing, thus avoiding the collection of core privacy information such as user images at the source. This effectively prevents user privacy and security issues caused by image information leakage, allowing users to enjoy intelligent rest intervention services without worrying about the excessive collection and misuse of their personal privacy. Therefore, this embodiment provides intelligent rest intervention services while avoiding the excessive collection and misuse of personal privacy, effectively enhancing users' trust in the vehicle's intelligent functions and their sense of security.
[0033] For example, please refer to Figure 2When a user activates the rest mode in the vehicle and falls asleep in a 135° reclining position, snoring begins. A four-channel microphone array in the vehicle's cabin continuously collects raw audio signals containing the user's snoring, air conditioning background noise, and ambient noise at a 48kHz sampling rate. Beamforming technology then focuses the microphone array's pickup direction towards the user's head area, filtering out interference from other directions in the cabin. An adaptive filtering algorithm further removes background noise such as air conditioning fan noise and low-frequency vehicle vibrations, outputting a clean snoring signal. Next, temporal and frequency domain features are extracted from the noise-reduced snoring signal and compared with pre-stored normal breathing characteristic thresholds. A decision controller determines if a breathing abnormality event is detected. Based on a moderately significant level, a preset abnormal state-control parameter mapping table is invoked to generate an adjustment command, which is then sent to the seat motor actuator via the CAN bus. Upon receiving the command, the seat motor actuator drives the seat back adjustment motor, gently adjusting the backrest from 135° to 138°. The entire process is conducted with a perceived intensity below the user's wake-up threshold, ensuring no disruption to sleep. After the adjustment is completed, the microphone array continues to collect audio. If the amplitude of the user's snoring drops from 0.5V to 0.3V and the breathing cycle returns to stability, the system determines that the intervention is effective and maintains the current seat angle. If the snoring does not subside or even worsens, the decision controller continues to adjust or triggers multi-dimensional adjustments.
[0034] This embodiment uses an in-vehicle microphone to collect cabin audio and identify abnormal breathing events, effectively avoiding the limitations of traditional visual monitoring solutions. It achieves stable, non-contact monitoring of breathing states during parking and rest scenarios. Furthermore, by adapting and matching abnormal states with vehicle control parameters, it can proactively improve abnormal breathing states through targeted rest adjustments, providing active protection for the respiratory health of resting passengers. Simultaneously, through gradient adjustments adapted to abnormal states, it avoids the problems of insufficient intervention or excessive interference caused by fixed-intensity adjustments. While ensuring the effectiveness of respiratory abnormality intervention, it also fully considers the sleep experience of resting passengers, achieving intelligent in-vehicle health protection during rest.
[0035] Based on any of the above embodiments, in Embodiment 2 of this application, controlling the vehicle to perform a rest adjustment action based on vehicle control parameters includes step S31: Step S31: Adjust the backrest angle of the seats in the cabin based on the vehicle control parameters.
[0036] The perceived intensity generated during the adjustment of the seat back angle is lower than the wake-up threshold of the user inside the cabin.
[0037] In this embodiment, different abnormal states correspond to different vehicle control parameters. When the abnormal breathing event is continuous snoring and the sound gradually increases, the seat back motor can be controlled to work by fine adjustment.
[0038] Therefore, as an optional implementation, the current backrest angle of the cabin seat and a preset backrest angle can be determined first. The preset backrest angle is the angle corresponding to the most stable breathing state, and this angle can be customized by the user. If the current backrest angle of the cabin seat is greater than or equal to the preset backrest angle, the backrest angle of the cabin seat is raised based on a first adjustment amount; while if the current backrest angle of the cabin seat is less than the preset backrest angle, the backrest angle of the cabin seat is lowered based on a second angle adjustment amount. That is, when the seat descent angle is large, the backrest angle is raised relative to the reference angle, or when the current descent angle of the seat is lower than the reference angle, the backrest angle is lowered relative to the reference angle, thereby changing the angle of force on the user's neck, eliminating physical obstruction caused by the chin pressing on the chest or the tongue falling back, and improving the impact of snoring. The magnitudes of the first angle adjustment amount and the second angle adjustment amount can be equal or unequal, and this adjustment amount can be customized by the user or be a dynamically changing value after continuous iterative learning.
[0039] Understandably, after each adjustment of the seat back angle, the vehicle system receives real-time signals from the audio recognition module indicating abnormal breathing events. If the abnormal breathing events disappear within the preset time period after adjustment, or if the severity of the abnormality decreases, the angle can be adjusted again until the abnormal breathing events disappear.
[0040] For example, the vehicle system first acquires the current backrest angle of the seat in the cabin, which is 140°, and simultaneously retrieves the user's preset comfortable resting angle of 135°, which is the most stable breathing angle and the most unobstructed airway during the user's sleep state. If the current backrest angle is greater than the preset backrest angle of 135°, the vehicle system raises the seat backrest angle by a preset first adjustment amount of 3°, fine-tuning the seat backrest angle from 140° to 137°. Similarly, if the current backrest angle of the seat in the cabin is detected to be 130°, which is less than the preset backrest angle of 135°, the vehicle control system lowers the seat backrest angle by a preset second adjustment amount of 3°, fine-tuning the seat backrest angle from 130° to 133°. After each minor adjustment of the seat back angle, the vehicle control system receives the respiratory abnormality event recognition results from the audio recognition module in real time. It continuously tracks the changing trend of the respiratory abnormality state within a preset 10-second period after the angle adjustment. If the severity of the respiratory abnormality event is significantly reduced within this preset period, the vehicle control system continues to make gradual minor adjustments to the seat back angle in the same direction according to the corresponding adjustment amount. The operation of angle adjustment and respiratory status monitoring is repeated until the audio recognition module detects that the respiratory abnormality event has been completely eliminated.
[0041] As another optional implementation, if the user does not set a preset backrest angle, the backrest angle of the cabin seat can be raised or lowered sequentially based on the user-defined adjustment sequence and the third angle adjustment amount. The changes in the current abnormal breathing event will be continuously tracked within a preset period after each adjustment. For example, if the snoring frequency decreases significantly after lowering the backrest angle, the backrest angle will be lowered continuously until the abnormal breathing event disappears.
[0042] Understandably, snoring and breathing difficulties experienced by resting passengers are primarily caused by improper sleeping posture leading to physical compression of the airway / retraction of the tongue. Adjusting the seat back angle directly changes the user's upper body posture, clearing the airway and relieving physical obstruction, thus quickly alleviating breathing abnormalities at their physiological root. Poor air circulation, reduced oxygen concentration, and carbon dioxide accumulation within the cabin exacerbate breathing difficulties and snoring. Therefore, in addition to adjusting the seat back angle, the air conditioning airflow can also be adjusted as a supplementary method. Optionally, the seat's vibration motor can be used for gentle vibration as a further auxiliary adjustment. Furthermore, the seat's vibration motor can be directly activated to perform gentle vibrations and / or adjust the air conditioning airflow, thereby reducing snoring.
[0043] This embodiment, without interrupting the user's sleep, utilizes the physical movement of the seat motor to adjust the seat back angle using a micro-adjustment method, directly intervening in and improving the occupant's physical posture, thereby reducing the user's snoring. Compared to the traditional DMS system that detects fatigue and wakes the user, this can fundamentally solve the breathing abnormality problem caused by improper sleeping posture, improve the user's sleep quality and travel comfort, and avoid the sleep interruption and discomfort that may be caused by traditional wake-up methods.
[0044] Furthermore, controlling the vehicle to perform a rest adjustment action based on vehicle control parameters includes step S32: Step S32: Drive the vibration motor of the seat in the cabin, adjust the brightness of the ambient light and / or adjust the air volume and air outlet angle in the cabin based on the vehicle control parameters.
[0045] The perceived intensity generated by vibration of the vibration motor, adjustment of ambient light brightness and / or changes in air volume and air outlet angle is lower than the wake-up threshold of the user in the cabin.
[0046] In this embodiment, in addition to adjusting the breathing state of the user in the cabin by fine-tuning the seat angle, adjustments can also be made by tactile vibration and / or light source sensing.
[0047] Specifically, as an optional implementation, only the vibration motor of the seat inside the cabin can be driven. In this process, the vehicle system drives the vibration motor built into the seat to operate at a preset amplitude, preset frequency, and preset time according to the vehicle control parameters corresponding to the abnormal breathing state. For example, the vibration motor in the seat is driven to generate a pulse vibration at a frequency of 40-60Hz that is insufficient to wake the user, lasting for 2-3 seconds. This gently soothes the user's throat muscles through mild physical stimulation when the user is in a long-term silent state or snoring, reduces airway obstruction caused by the tongue falling back, and helps relieve snoring and breathing difficulties. It forces the body to resume spontaneous breathing without waking the user.
[0048] As another optional implementation, the vehicle system can make small-amplitude adjustments to the ambient lighting in the cabin based on the vehicle control parameters corresponding to the abnormal breathing state. The gradual changes in brightness avoid sudden changes in brightness, thereby indirectly providing the user with a subtle sensory cue through gentle light changes. This helps to awaken the muscle regulation awareness in the light sleep state, while creating a soothing cabin environment to prevent the user from feeling anxious due to breathing difficulties and to help maintain stable breathing.
[0049] As an alternative implementation, the vehicle system gradually increases the air conditioning output based on the vehicle control parameters corresponding to the abnormal breathing state. This ensures air circulation without strong wind impact, thereby accelerating air circulation within the cabin, increasing oxygen concentration, reducing carbon dioxide accumulation, alleviating breathing obstruction exacerbated by hypoxia and stuffiness, optimizing the breathing environment, and indirectly reducing snoring and the degree of breathing obstruction. Furthermore, while adjusting the air conditioning output, the airflow angle can also be adjusted. A gentle airflow blowing onto the user's face and neck stimulates slight contraction of the muscles around the respiratory tract, clearing narrowed airways while maintaining airflow around the mouth and nose, further assisting in relieving breathing obstruction, thus indirectly achieving the effect of adjusting the airflow.
[0050] As an alternative implementation, the air conditioning system can be adjusted in conjunction with the seat vibration motor. This involves a sudden increase in cold airflow or a change in airflow direction to directly blow on the face during seat vibration, using hot and cold stimulation to induce muscle contraction. Specifically, the vehicle control system simultaneously drives the low-intensity vibration motor and adjusts the airflow, thereby using tactile feedback to induce micro-awakening, increasing throat muscle tension, and forcing the body to resume spontaneous breathing without fully waking the person.
[0051] As an alternative implementation, the vehicle system simultaneously executes low-intensity vibration motor drive and progressive ambient light brightness adjustment. Through slight physical stimulation and soft light cues, it dually assists in activating the user's throat muscles and maintaining steady breathing, relieving breathing congestion from both physical and sensory dimensions.
[0052] As another optional implementation, the vehicle system simultaneously adjusts the airflow and ambient light brightness, stimulating the respiratory tract with directional, gentle airflow while also providing stimulation through soft light, thereby enhancing the breathing effect.
[0053] As another optional implementation method, the vehicle system synchronously and collaboratively executes low-amplitude vibration of the vibration motor, gradual dimming of ambient lighting, increased air volume of air conditioning and directional deflection of air outlet angle according to vehicle control parameters. Through four functions of physical stimulation, sensory soothing, air circulation and directional airway unblocking, it comprehensively assists in relieving breathing obstruction caused by tongue falling back, muscle relaxation, and hypoxia and stuffiness, maximizing the relief effect of breathing abnormalities without waking the user.
[0054] It should be noted that the above adjustments are all achieved using the vehicle's existing cabin components, without the need for new hardware or for users inside the cabin to wear sensors.
[0055] In this embodiment, when performing rest and adjustment actions, lightweight, low-impact intervention can be achieved through a single device, or enhanced intervention can be achieved through a combination of multiple devices. This perfectly adapts to different users' rest habits and varying degrees of respiratory obstruction. Simultaneously, all adjustment actions are non-awakening and gentle, relieving respiratory obstruction without interfering with the user's normal rest, achieving a balance between respiratory health protection and sleep experience. During the multi-dimensional adjustment process, multiple levels of synergistic effects, including somatosensory stimulation, respiratory environment optimization, airway unblocking, and sensory soothing, are utilized. Compared to single-mode intervention, this is more effective in relieving respiratory obstruction, avoiding under- or over-intervention.
[0056] Based on the second embodiment described above, in the third embodiment of this application, after step S31, step S33 is further included: Step S33: If the abnormal breathing event still exists after adjusting the backrest angle, and the level of the abnormal state remains unchanged or increases, then the vibration motor of the seat in the cabin is driven, the brightness of the ambient light is adjusted, and / or the air volume in the cabin is adjusted based on the vehicle control parameters.
[0057] In this embodiment, in addition to fine-tuning based on the seat angle or providing sensory stimulation, if the adjustment effect based on the seat angle is poor, further sensory stimulation adjustments can be made. Therefore, when the vehicle system performs a rest adjustment action based on vehicle control parameters, it first adjusts the backrest angle of the seat in the cabin, and then detects whether there are still abnormal breathing events within a preset time period after adjusting the backrest angle. If there are, and the degree of the abnormal state corresponding to the abnormal breathing event remains unchanged or shows an increasing trend, it indicates that simply adjusting the seat backrest angle has not effectively improved the user's breathing condition. At this time, the vehicle system will trigger further multi-dimensional sensory stimulation adjustments.
[0058] Specifically, when adjusting the backrest angle yields minimal results, the vehicle system activates the vibration motors built into the seats, inducing micro-awakening through preset low-frequency vibration modes. This enhances throat muscle tension and automatically adjusts the brightness and color temperature of the ambient lighting to create a soft, soothing visual environment, avoiding glare and helping the user remain relaxed. Furthermore, the vehicle's air conditioning system adjusts the airflow and introduces filtered fresh air based on the current cabin temperature and user preferences. This ensures air circulation while maintaining suitable temperature and humidity, reducing respiratory discomfort caused by dry air or odors. Through coordinated regulation of multiple senses—touch, sight, and touch—it comprehensively intervenes in respiratory abnormalities, improving the user's respiratory comfort and safety during rest. If adjusting the backrest angle fails to meet the needs, further adjustments will be made based on the specified methods.
[0059] It should be noted that the adjustment process of adjusting the backrest angle based on the vehicle control parameters can be done multiple times, or after adjusting for a preset period of time, the processing action of step S33 is executed. That is, after step S31, the processing action of step S32 is executed when the aforementioned conditions are met.
[0060] It is understandable that fine-tuning the seat angle is a fundamental, minimally disruptive, and highly efficient physical intervention, while sensory stimulation is an auxiliary, more perceptible, and indirectly effective supplementary intervention. The adjustment between the two should follow the logic of first providing a light, fundamental intervention, and then strengthening the auxiliary intervention. Therefore, this embodiment prioritizes fine-tuning the seat angle as a mild intervention, and uses sensory stimulation as a subsequent, enhanced supplementary means. This approach can quickly alleviate mild breathing abnormalities at their source while minimizing interference with the user's rest. Simultaneously, it strictly adheres to the gradient adjustment logic where the more pronounced the abnormality, the more obvious the adjustment perception, ensuring the rationality, effectiveness, and comfort of the intervention, achieving the optimal balance between alleviating breathing abnormalities and the restful experience.
[0061] Based on the second embodiment described above, in the fourth embodiment of this application, after step S32, step S34 is further included: Step S34: If there is an abnormal breathing event and the level of the abnormal state increases, adjust the backrest angle of the cabin seats based on the vehicle control parameters to restore the cabin seats to the preset backrest angle.
[0062] In this embodiment, when controlling the vehicle to perform rest adjustment actions based on vehicle control parameters, step S31, adjusting the backrest angle, can be performed first. Then, if the adjustment effect does not meet the requirements (i.e., the degree of abnormality remains unchanged or increases), the multi-dimensional sensory stimulation adjustment action in step S32 can be performed. After this, if abnormal breathing events still occur and the degree of normality shows an increasing trend, it indicates that the aforementioned two adjustment methods are ineffective and frequent sleep apnea / snoring still exists. In this case, a full wake-up procedure needs to be executed to prevent the user from falling into potential health risks due to persistent abnormal breathing events.
[0063] Therefore, by restoring the cabin seat to a preset backrest angle—that is, adjusting the seat backrest to the angle of a normal sitting posture—the user's body posture is altered. This large-angle posture change effectively opens the user's airway, reducing the obstruction of the airway by soft tissues in the upper respiratory tract. The preset backrest angle is the backrest angle in a normal sitting posture, such as 95-110°.
[0064] Understandably, restoring the seat back angle to the preset angle will usually wake the user. Therefore, in addition to adjusting the backrest angle, preset wake-up prompts for the user can also be output, such as wake-up audio.
[0065] In addition, the processing action of step S35 can be performed directly after step S32 without performing step S31. That is, when the effect of multi-dimensional sensory stimulation does not meet the needs, the user is awakened by adjusting the seat angle.
[0066] This embodiment employs a three-tiered progressive adjustment strategy: first, fine-tuning the backrest; then, multi-dimensional sensory stimulation; and finally, initiating a full wake-up procedure. This strategy prioritizes user rest and comfort in a gentle, non-awakening manner, alleviating mild to moderate respiratory abnormalities at their source. Furthermore, when the first two types of adjustments are ineffective and respiratory abnormalities continue to worsen, the forced intervention of a large-angle seat repositioning and full wake-up can promptly relieve severe airway obstruction. This achieves intelligent protection across all scenarios and levels, enhancing the targetedness and reliability of respiratory abnormality intervention, from the perspectives of rest comfort and life health safety.
[0067] Based on any of the above embodiments, in Embodiment 5 of this application, in addition to non-sensory wake-up, if the detected abnormal breathing event involves frequent breathing pauses in the cabin user, or if the duration of breathing pauses exceeds a preset safety threshold, the vehicle system can directly trigger an active wake-up mechanism.
[0068] Therefore, step S20 is followed by step S40: Step S40: If the abnormal state meets the preset wake-up state, adjust the backrest angle of the cabin seat based on the vehicle control parameters so that the cabin seat returns to the sitting position.
[0069] In this embodiment, if the abnormal state corresponding to the abnormal breathing event meets the preset wake-up state, the backrest angle of the cabin seat is adjusted based on the vehicle control parameters to restore the cabin seat to the preset backrest angle, and / or a preset cabin user wake-up prompt message is output. For example, the system will drive the audio output module to play soft natural sound effects (such as the sound of flowing water or birdsong) or a preset wake-up prompt tone, while controlling the seat to rise to the angle corresponding to a normal sitting posture, thereby waking up the user. The preset wake-up state can be a level that the severity of breathing obstruction will endanger the user's health, preset by the vehicle. This level can also be set by the user based on actual conditions, or it can be optimized iteratively through self-learning by the vehicle system.
[0070] This embodiment sets up a graded early warning mechanism for severe respiratory abnormalities that endanger physical health. Based on the dual intervention of seat repositioning and wake-up prompts, the treatment of respiratory abnormalities is upgraded from gentle relief to safe wake-up, effectively protecting the respiratory health and personal safety of users during rest.
