Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a method, apparatus, system, control device, and vehicle for self-cleaning vehicle seats. Background Technology

[0002] In scenarios such as family car use, business reception, ride-sharing, and long-distance commuting, seats are prone to accumulating dust, hair, dander, food residue, and liquid stains due to their frequent use.

[0003] Currently, maintaining seat cleanliness primarily relies on manual cleaning. Common cleaning methods include using a handheld car vacuum cleaner to remove dust and hair from the seat surface, wiping localized stains with a damp cloth or cleaning wipes, and using lint rollers or cleaning gels to remove debris from crevices. Specifically, when users find obvious dirt on the seat surface, they need to manually hold the vacuum cleaner, moving the nozzle back and forth against the seat cushion and backrest surface. The negative pressure generated by the vacuum cleaner's internal motor sucks the loose particles attached to the surface into the dust collection chamber. For narrow areas such as seat edge crevices and seam grooves, a flat nozzle is needed for deeper cleaning. If there are liquid spills or sweat residue on the seat surface, users usually first wipe repeatedly with a damp cloth dipped in cleaning solution, then use a dry cloth to absorb the surface moisture. For small dust particles embedded in the ventilation holes of perforated leather seats, some users will use cleaning gel to press into the holes and remove them.

[0004] However, manual cleaning methods are costly and have poor cleaning results. Summary of the Invention

[0025] If the humidity value of the cabin environment is greater than the preset humidity threshold and the humidity value of the seat is not greater than the preset humidity threshold, then the value obtained by multiplying the first preset duration coefficient corresponding to the humidity value of the cabin environment in the second mapping relationship by the preset duration is determined as the second duration.

[0082] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0083] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0084] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0085] First, the application scenarios involved in this application will be explained:

[0086] As vehicles evolve towards intelligent cockpits and multifunctional passenger spaces, seats are no longer merely responsible for supporting occupants. They are increasingly integrating various comfort and health features such as ventilation, heating, massage, and surface sterilization. In scenarios such as family cars, business receptions, shared mobility, and long commutes, seats are frequently used and easily accumulate dust, hair, dander, food residue, and liquid stains. If not cleaned promptly, mold can easily grow. These contaminants often not only remain on the surface but also penetrate into crevices, pores, and internal filling layers, causing visual dirt, odor growth, and microbial proliferation. These problems are particularly pronounced when using the vehicle with children or pets, and maintaining seat cleanliness becomes significantly more difficult in humid climates or high-humidity environments.

[0087] To maintain seat cleanliness, current technology typically employs two cleaning methods: manual wiping or external portable vacuum cleaners. Specifically, when users find visibly dirty seat surfaces, they need to manually hold the vacuum cleaner, moving the nozzle back and forth against the seat cushion and backrest. The negative pressure generated by the vacuum cleaner's internal motor draws loose particles into the dust collection chamber. For narrow areas such as seat edges, seams, and grooves, a flat nozzle is used for deeper cleaning. If there are liquid spills or sweat residue on the seat surface, users usually first wipe repeatedly with a damp cloth dipped in cleaning solution, then blot away the surface moisture with a dry cloth. For fine dust particles embedded in the ventilation holes of perforated leather seats, some users use cleaning gel, pressing it into the holes to adhere and remove them.

[0088] However, manual cleaning relies heavily on the user's schedule and initiative. In most cases, cleaning is only done when dirt is visible to the naked eye, leaving the seats to accumulate grime and become unsanitary corners. Secondly, handheld vacuum cleaners are limited by suction power attenuation and insufficient nozzle fit in areas deep within seat crevices, perforated leather, and the foam padding, making it difficult to effectively penetrate deep-seated particles. Wiping with a damp cloth only works on the surface, and residual moisture can easily seep into the foam through seams or vents, creating a humid environment conducive to mold and bacteria growth.

[0089] In summary, existing technologies suffer from poor cleaning performance and high labor costs.

[0090] Based on the aforementioned technical problems, the technical concept of this application is as follows: During the research of vehicle seat self-cleaning technology, the inventors discovered that existing manual cleaning methods are ineffective in removing dust and debris from seat crevices and deep within the filling layers, resulting in poor cleaning performance and high labor costs due to heavy reliance on manual operation. Further analysis revealed that the seat's built-in massage module has a vibration and tapping function. While the ventilation module is blowing air, the massage module can simultaneously perform a massage operation, using positive pressure airflow and repeated tapping to automatically drive deep-seated dust and debris to the surface. Furthermore, when the ventilation module performs a suction operation, loose dust on the seat surface is sucked into the seat interior, thus achieving dust recycling. The entire process can be executed automatically when the vehicle determines that the seat meets the self-cleaning activation conditions, requiring no manual intervention and reducing labor costs. Moreover, the synergistic mechanism of blowing and tapping to dislodge particles and suction to collect dust achieves thorough cleaning of deep-seated dust and debris from the seat, thereby improving the cleaning effect.

[0091] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0092] It should be understood that the vehicle seat self-cleaning method provided in this application embodiment is applied to the control device of the vehicle seat self-cleaning system. Before introducing the vehicle seat self-cleaning method, the vehicle seat self-cleaning system will be explained first.

[0093] The vehicle seat self-cleaning system provided in this application includes a seat body and a ventilation module, a massage module, and a control device integrated inside the seat body.

[0094] The ventilation module includes a ventilation duct unit, which is used for airflow circulation. The ventilation duct unit is equipped with a bidirectional fan that can rotate in both directions. When the bidirectional fan rotates in the forward direction, it creates a positive pressure airflow to perform a blowing operation, and when it rotates in the reverse direction, it creates a negative pressure airflow to perform a suction operation.

[0095] Understandably, when the bidirectional fan rotates forward, the air vents on the seat surface act as air outlets; when the bidirectional fan rotates in reverse, the air vents on the seat surface act as air inlets. The switching between blowing and suction airflow modes can be achieved simply by using the same air vent in conjunction with the forward and reverse rotation of the bidirectional fan. This simplifies the air duct structure, reduces the number of openings on the seat surface, and minimizes the impact on the seat's appearance and comfort.

[0096] The massage module's airbags are repeatedly inflated and deflated to vibrate and pat the seat surface during the blowing operation, driving dust particles hidden in the seat gaps and deep filling layers to the surface.

[0097] Optionally, a heating module is also coupled into the ventilation duct unit of the ventilation module. The heating module is used to heat and dry the air drawn into the ventilation duct unit and maintain it at a preset mite-removal temperature to achieve thermal mite removal treatment.

[0098] Optionally, the ventilation module may also include an ultraviolet sterilization module, for example, which may be deployed at the air outlet of the ventilation duct unit. This ultraviolet sterilization module is used to irradiate the inner wall of the ventilation duct unit and the internal airflow with ultraviolet light to inactivate bacteria and mites.

[0099] Optionally, an air filter module is also installed in the ventilation duct unit of the ventilation module to capture dust particles such as dust, hair, and dander that are inhaled into the ventilation duct unit. After the inhaled dust particles are intercepted and captured by the air filter module, clean air is discharged to the outside from the exhaust port at the bottom of the seat.

[0100] The main body of the seat serves as the installation base for the vehicle seat self-cleaning system, and it also integrates pressure sensors, humidity sensors, and temperature sensors.

[0101] Specifically, the pressure sensor is used to detect whether there are occupants in the target seat to determine whether the self-cleaning start conditions are met; the humidity sensor is used to detect the real-time humidity value of the seat (i.e., the seat humidity value); and the temperature sensor is used to detect the real-time temperature value of the seat body.

[0102] Furthermore, the control device is communicatively connected to the ventilation module, massage module, pressure sensor, humidity sensor, temperature sensor, heating module, and ultraviolet sterilization module, and is also communicatively connected to the vehicle's display head unit (DHU), seat cleaning software switch, and humidity sensor of the cabin heating, ventilation and air conditioning (HVAC) system.

[0103] In practical applications, the control device can be a vehicle infotainment system, a seat controller, a vehicle controller, or a domain control unit connected to the seat function. It can be determined according to the actual situation, and this application embodiment does not impose specific restrictions on it.

[0104] The DHU seat cleaning software switch is used to receive user input of self-cleaning start / stop commands for a single seat or all seats in the vehicle, and sends the self-cleaning start / stop commands to the control device; the control device is used to control the modules to coordinately execute the vehicle seat self-cleaning method of this application embodiment based on real-time detection data from sensors such as pressure sensors, humidity sensors, temperature sensors, and cabin HVAC humidity sensors.

[0105] Figure 1 A flowchart illustrating the vehicle seat self-cleaning method provided in this application embodiment. Figure 1 ,like Figure 1 As shown, the method includes:

[0106] S11. When the target seat of the vehicle meets the self-cleaning start conditions, control the ventilation module in the target seat to perform a blowing operation and control the massage module in the target seat to perform a massage operation.

[0107] The target seat refers to the seat in the vehicle that needs to be cleaned, which can be the driver's seat, the front passenger seat, or any independent seat in the rear.

[0108] The self-cleaning start condition is used to characterize whether the target seat is currently suitable for entering the automatic cleaning mode. In practical applications, the self-cleaning start condition includes that the self-cleaning function of the target seat is turned on and that there are no occupants in the target seat.

[0109] Specifically, the self-cleaning function is managed by the control device. Users can issue a command to activate the self-cleaning function for a target seat via the DHU interface, voice commands, mobile applications, or physical buttons. The control device then activates the self-cleaning function for the target seat based on this command. The self-cleaning function can also be activated automatically according to preset strategies. For example, if a high probability of dust particle contamination is detected on the seat surface within a certain period after the vehicle is parked, turned off, locked, and powered off, the self-cleaning function for the target seat will be automatically activated.

[0110] Optionally, a higher probability of dust particle contamination can be defined as the time elapsed since the last self-cleaning process exceeds a preset maximum cleaning time. For example, if the target seat has not been cleaned for a month, then the target seat is considered to have a higher probability of dust particle contamination.

[0111] The "no occupant in target seat" condition indicates that the target seat is in an vacant state. This can be determined by pressure sensors placed inside the seat cushion or in the frame of the target seat. Alternatively, it can be cross-checked by the seat belt buckle status, door opening and closing status, infrared detection module, and in-vehicle camera recognition results to reduce the probability of false triggering.

[0112] In practical applications, the infrared detection module can be placed above the seat back or on the side of the ceiling to detect the infrared information of the target seat, thereby improving the sensitivity of occupancy detection.

[0113] In practice, after the self-cleaning function is activated, the control device can continuously check the occupancy status of the target seat. If the target seat is detected to be occupied during the cleaning preparation period, the subsequent cleaning control is paused, and the remaining cleaning process is resumed from the interrupted step or the cleaning process is started from the beginning after the target seat is freed.

[0114] The aforementioned self-cleaning start conditions ensure that massage and air suction functions are performed only when the seat is unoccupied, avoiding discomfort to occupants and reducing energy waste caused by accidental triggering.

[0115] Based on the above self-cleaning start condition determination, the subsequent cleaning control will only be initiated when the self-cleaning function for the target seat is activated and there are no occupants in the target seat. This ensures that dust particles on and inside the seat can be driven away, gathered and removed without human interference, thus guaranteeing the safety and accuracy of the cleaning process.

[0116] Optionally, after confirming that the target seat meets the self-cleaning activation conditions, an initialization process can be performed first. This initialization process may include reading the target seat model, reading the massage module layout information, and determining the air intake position of the ventilation module, and limiting the intensity of subsequent actions based on the type of seat surface material. For example, for fabric seats, higher frequency micro-vibrations or shorter cycle airbag undulations can be set to improve the ability to loosen attached dust particles. For perforated leather seats, the massage displacement amplitude and duration can be controlled to avoid excessive localized pressure on the surface. For composite material seats, different massage parameters can be used for the seat cushion, backrest, and side wing areas.

[0117] The blowing operation refers to controlling the ventilation module to generate positive pressure airflow, which blows the airflow outward from the inside of the seat through the decorative holes, vents and gaps on the seat surface, blowing away dust particles hidden in these areas to the seat surface.

[0118] The massage operation refers to controlling the massage module to apply repeated mechanical vibration or squeezing and patting to the seat surface, so that the dust and debris deep in the filling layer are loosened by the patting action and migrated to the top of the seat surface.

[0119] In one possible implementation, the bidirectional fan in the ventilation module can be controlled to rotate forward to create a positive pressure airflow.

[0120] The massage module can include either a vibration massage unit or an airbag massage unit. When using an airbag massage unit, the airbags repeatedly inflate and deflate in a preset direction, gradually squeezing from deep within the seat padding layer towards the seat surface, loosening dust adhering to the target seat surface. When using a vibration massage unit, the vibration unit applies high-frequency micro-vibrations to the seat surface at a preset frequency and amplitude, causing fine particles adhering to the target seat surface to loosen and fall off.

[0121] In practical applications, the air blowing and massage operations can be performed simultaneously. Positive pressure airflow blows from inside the seat outwards, transporting loosened dust particles towards the surface and air intake; at the same time, the repeated tapping of the massage module continuously applies mechanical force to the filling layer, preventing particles from re-adhering due to static electricity or moisture. Alternatively, the air blowing operation can be performed first, followed by the massage operation, or vice versa.

[0122] In other words, this application does not impose specific restrictions on the execution order of the blowing operation and the massage operation.

[0123] S12. When the duration of the blowing operation reaches the first duration, control to stop the blowing operation.

[0124] In one possible implementation, the first duration is a predefined duration, such as 5 minutes, 10 minutes, 15 minutes, etc.

[0125] In another possible implementation, the first duration is determined based on the humidity value of the target seat and a preset humidity threshold.

[0126] In practical applications, the humidity value of the target seat can be collected by a humidity sensor deployed inside the target seat.

[0127] Specifically, the humidity difference between the seat humidity value and the preset humidity threshold can be calculated, and the first duration can be determined based on the humidity difference and the first mapping relationship.

[0128] The first mapping relationship is used to represent the correspondence between humidity difference and duration. In the first mapping relationship, duration and humidity difference are positively correlated.

[0129] Specifically, a first mapping relationship between humidity difference and duration can be established in advance, and the control device can query the first duration corresponding to the first mapping relationship based on the humidity difference calculated in real time.

[0130] For example, when the humidity difference is 0 (i.e., the seat humidity value is equal to the preset humidity threshold), the first duration can be the preset baseline blowing duration; when the humidity difference is greater than 0, the first duration increases by a preset step size based on the preset baseline blowing duration. For each preset unit increase in humidity difference, the first duration is extended by a preset increment until the preset maximum blowing duration limit is reached.

[0131] In this implementation, when the seat humidity is high, the airflow and patting are more thorough, effectively preventing dust particles from sticking to the seat surface due to moisture and becoming difficult to remove, thus improving the efficiency of loosening and removing deep-seated particles. When the humidity is low, the initial blowing time is also shortened accordingly to reduce energy consumption and avoid excessive airflow.

[0132] It should be understood that the massage operation can be stopped simultaneously when the duration of the blowing operation reaches the first duration, or it can be stopped after S13 is completed, or it can be stopped some time after the blowing operation has stopped. In other words, the embodiments of this application do not impose specific restrictions on the timing of stopping the massage operation.

[0133] S13, Control the ventilation module to perform air intake operation.

[0134] The suction operation refers to controlling the ventilation module to generate negative pressure airflow, which draws the airflow into the air duct from the decorative holes, vents and gaps on the seat surface. This draws in dust particles, hair, dander and other debris that were previously blown onto the seat surface, and then intercepts and collects them through the air filtration module.

[0135] In one possible implementation, the bidirectional fan is controlled to reverse to create a negative pressure airflow.

[0136] The vehicle seat self-cleaning method provided in this application, when the target seat meets the self-cleaning activation conditions, controls the ventilation module in the target seat to perform a blowing operation and controls the massage module in the target seat to perform a massage operation. When the blowing operation lasts for a first duration, the blowing operation is stopped, and the ventilation module is controlled to perform a suction operation. In this technical solution, positive pressure blowing and massage tapping actively drive deep-seated dust and debris to the surface, and negative pressure suction recovers dust from the seat surface, achieving effective removal of deep-seated particles from the seat and improving the cleaning effect. The entire cleaning process is automatically executed after the vehicle determines that the conditions are met, without manual intervention, reducing labor costs.

[0137] Furthermore, in some embodiments, after S13, the heating module coupled in the ventilation module can also be controlled to perform a heating operation to heat the air drawn in by the ventilation module to a preset mite-removal temperature.

[0138] The heating module is thermally coupled to the ventilation duct unit. The heating operation refers to heating the air drawn in by the ventilation module to a preset mite-removal temperature and maintaining it.

[0139] Understandably, after the bidirectional fan of the ventilation module continues to reverse, the heating module begins to perform the heating operation. The two work together to ensure that the seat filling layer and surface material are fully dried and mites are inactivated under the continuous action of hot air.

[0140] Optionally, after the heating module of the target seat heats the air drawn in by the ventilation module to a preset mite-removal temperature, the ultraviolet sterilization module of the target seat can also be controlled to perform an irradiation operation for a certain period of time to enhance the sterilization and mite-removal effect.

[0141] For example, the duration of the ultraviolet irradiation can be set to a preset fixed duration, such as 10 minutes, 15 minutes, 20 minutes, etc., which can be preset based on empirical or experimental values. This application embodiment does not impose specific limitations on this.

[0142] In this method, the combined effects of thermal inactivation and ultraviolet inactivation can further enhance the sterilization and disinfection effect on the basis of drying and mite removal, thereby achieving deep purification of the seat interior and air duct, and thus comprehensively improving the seat's self-cleaning effect.

[0143] The heating module can use a positive temperature coefficient (PTC) heating element, resistance heating wire or other seat heating element, which is installed inside the foam layer of the seat cushion or backrest. A heat insulation buffer layer can be set between its outer surface and the seat fabric to reduce the impact of local hot spots on the seat material.

[0144] For example, the preset mite removal temperature can be set to a temperature threshold that can inactivate mites, inhibit the reproduction of microorganisms, and not significantly damage the seat fabric, such as 55°C, 60°C, or 65°C. It can be preset based on empirical or experimental values, and this application embodiment does not impose specific limitations on it.

[0145] Based on the above embodiments, the heating operation can also be stopped when the duration of the heating operation reaches a second duration.

[0146] In one possible implementation, the second duration can be determined based on the humidity value of the target seat, the humidity value of the vehicle cabin environment, and a preset humidity threshold.

[0147] In practical applications, humidity values ​​of the vehicle cabin environment can be obtained by deploying humidity sensors inside the cabin.

[0148] Specifically, the second duration can be determined in the following ways:

[0149] If the humidity value of the cabin environment is not greater than the preset humidity threshold, and the humidity value of the seat is not greater than the preset humidity threshold, then the preset duration will be set as the second duration.

[0150] If the humidity value of the cabin environment is greater than the preset humidity threshold, and the humidity value of the seat is not greater than the preset humidity threshold, then the value obtained by multiplying the first preset duration coefficient corresponding to the cabin environment humidity value in the second mapping relationship by the preset duration is determined as the second duration.

[0151] If the humidity value of the cabin environment is not greater than the preset humidity threshold, and the humidity value of the seat is greater than the preset humidity threshold, then the value obtained by multiplying the second preset duration coefficient corresponding to the seat humidity value in the third mapping relationship by the preset duration is determined as the second duration.

[0152] If the humidity value of the cabin environment is greater than the preset humidity threshold, and the humidity value of the seat is greater than the preset humidity threshold, then the value obtained by multiplying the maximum value of the first preset duration coefficient and the second preset duration coefficient by the preset duration is determined as the second duration.

[0153] The second mapping relationship is used to indicate the correspondence between the cabin ambient humidity value and the preset duration coefficient, and the third mapping relationship is used to indicate the correspondence between the seat humidity value and the preset duration coefficient.

[0154] In practical applications, the second and third mapping relationships can be pre-stored in the storage unit of the vehicle control device and established using methods such as table lookup, piecewise mapping, or function fitting.

[0155] In actual control, after receiving the humidity values ​​of the cabin environment and the seats, the control equipment first compares them with preset humidity thresholds to determine the overall humidity scenario of the cabin and the local humidity scenario of the seats. When both the cabin environment humidity value and the seat humidity value do not exceed the preset humidity threshold, it indicates that the environment is relatively dry, which is the normal mode. The control equipment directly uses the preset duration as the second duration to meet the basic dust control and drying requirements. When the cabin environment humidity value or the seat humidity value exceeds the preset humidity threshold, it is necessary to determine the cause of the humidity exceeding the standard, that is, to determine whether the cabin interior is highly humid, whether there is localized liquid spray on the target seat, or both.

[0156] Furthermore, when the cabin ambient humidity exceeds a preset humidity threshold while the seat humidity does not, the cabin is determined to be highly humid. The control device determines a first preset duration coefficient based on the cabin ambient humidity in a second mapping relationship, and multiplies this coefficient by a preset duration to obtain a second duration applicable to the high humidity scenario throughout the cabin. When the cabin ambient humidity does not exceed the preset humidity threshold while the seat humidity exceeds it, localized water spraying is determined on the target seat. The control device determines a second preset duration coefficient based on the seat humidity in a third mapping relationship and calculates the second duration accordingly. When both exceed the preset humidity threshold, it indicates that not only is the entire cabin highly humid, but the target seat also has localized water spraying. The control device obtains the first and second preset duration coefficients respectively, and takes the larger coefficient multiplied by the preset duration as the second duration to ensure sufficient heating duration under conditions of combined high humidity.

[0157] The preset duration can be set to a fixed value or updated based on seat material, airflow resistance, and historical cleaning results.

[0158] Through the above method, the control device can adjust the second drying time in stages based on the humidity levels of the vehicle cabin and the seats. This allows the heating and drying operation to maintain low energy consumption in dry environments while extending the second drying time in high-humidity environments to fully evaporate moisture. This control method helps improve the efficiency of deep seat drying and mite removal, reduces insufficient drying or overheating caused by humidity differences, and makes the determination of the second drying time more targeted and adaptable, thereby improving the stability and consistency of the seat self-cleaning process.

[0159] Optionally, in some embodiments, after controlling the heating operation to stop, the ventilation module can also be controlled to stop the suction operation, and then the ventilation module can be controlled to perform the blowing operation.

[0160] In practical applications, the ventilation module can be controlled to switch from suction to blowing operation, and it can also be controlled to perform blowing operation after a period of time has elapsed since suction operation was stopped. In other words, this embodiment does not specifically limit the time interval between controlling the ventilation module to stop suction operation and controlling it to perform blowing operation.

[0161] Optionally, the blowing operation can be stopped after the blowing operation has lasted for a third duration.

[0162] In one possible implementation, the third duration can be determined based on the seat humidity value, the cabin ambient humidity value, and a preset humidity threshold.

[0163] It should be understood that the method for determining the third duration is the same as the principle for determining the second duration, as detailed below:

[0164] If the humidity value of the cabin environment is not greater than the preset humidity threshold, and the humidity value of the seat is not greater than the preset humidity threshold, then the preset duration will be set as the third duration.

[0165] If the humidity value of the cabin environment is greater than the preset humidity threshold, and the humidity value of the seat is not greater than the preset humidity threshold, then the value obtained by multiplying the first cooling time coefficient corresponding to the cabin environment humidity value in the fourth mapping relationship by the preset third time is determined as the third time.

[0166] If the humidity value of the cabin environment is not greater than the preset humidity threshold, and the humidity value of the seat is greater than the preset humidity threshold, then the value obtained by multiplying the second cooling time coefficient corresponding to the seat humidity value in the fifth mapping relationship by the preset third time is determined as the third time.

[0167] If the humidity value of the cabin environment is greater than the preset humidity threshold, and the humidity value of the seat is also greater than the preset humidity threshold, then the value obtained by multiplying the maximum value of the first cooling time coefficient and the second cooling time coefficient by the preset third time is determined as the third time.

[0168] The fourth mapping relationship is used to indicate the correspondence between the cabin ambient humidity value and the cooling time coefficient, and the fifth mapping relationship is used to indicate the correspondence between the seat humidity value and the cooling time coefficient.

[0169] In a real-world scenario, the control device continuously monitors the real-time temperature of the target seat using a temperature sensor. When the current temperature of the target seat is detected to be lower than a preset temperature threshold, it indicates that the heating, drying, and mite removal processes have been fully completed. This means that the suction and heating operations have been stopped, and the cooling phase begins. The control device then switches the bidirectional fan in the ventilation module to forward rotation to create a positive pressure airflow, blowing room-temperature air onto the seat surface to accelerate heat dissipation and cooling, allowing the seat temperature to return to a normal, usable state as quickly as possible.

[0170] For example, the preset temperature threshold can be set to 40℃, 45℃, or 50℃, which can be preset based on empirical or experimental values. This application embodiment does not impose specific limitations on this.

[0171] In this embodiment, by controlling the ventilation module to perform a blowing operation after the heating phase is completed, the cooling of the seat surface temperature is accelerated, avoiding the problem that the user cannot sit due to high temperature.

[0172] Optionally, in practical applications, the calculated durations (e.g., the first duration, the second duration, and the third duration) can be dynamically updated during the execution of their respective stages. Specifically, the control device resamples the cabin humidity and seat humidity values ​​at fixed intervals (e.g., every 2 minutes) and updates the remaining duration of the current stage based on the resampled cabin humidity and seat humidity values. Through this dynamic correction mechanism, the control device can adaptively adjust the remaining duration according to the real-time changes in humidity during the cleaning process, avoiding excessive or insufficient duration due to inconsistencies between the initial humidity state and the actual humidity state during the cleaning process. This reduces energy consumption and unnecessary heat exposure to seat materials while ensuring cleaning effectiveness, thereby improving the intelligence level and operational efficiency of the self-cleaning process.

[0173] Next, a specific example will be used to summarize and explain the above embodiments.

[0174] Figure 2 A flowchart illustrating the vehicle seat self-cleaning method provided in this application embodiment. Figure 2 ,like Figure 2 As shown, the method includes:

[0175] S201. Users can activate the self-cleaning function for the target seat by displaying the host unit DHU interface, using voice commands, mobile terminal applications, or physical buttons.

[0176] When a user selects to clean a single seat or all seats in the vehicle via the DHU interface, the DHU issues a command and enters a "waiting to leave the seat" listening state.

[0177] S202. The pressure sensor of the target seat detects whether there is no occupant in the target seat. If there is no occupant in the target seat, the self-cleaning process is initiated.

[0178] Once the pressure sensor confirms that the selected target seat is unoccupied, the cleaning process is initiated, and the DHU interface displays "Seat cleaning in progress".

[0179] S203. Based on the target seat's humidity value and a preset humidity threshold, determine the first duration and control the bidirectional fan to rotate forward to form a positive pressure airflow, which is used to blow up dust particles from the seat surface, decorative holes, or ventilation holes.

[0180] S204. During the first duration, the massage module is synchronously invoked to simulate the effect of human patting to prevent dust particles from sticking to the target seat due to excessive humidity.

[0181] S205 controls the bidirectional fan to reverse to generate negative pressure airflow, which draws the blown dust particles, as well as dust particles from the seat vents and crevices, into the ventilation duct unit, where they are captured by the filter module.

[0182] S206. Obtain the cabin ambient humidity value H_hvac collected by the cabin HVAC humidity sensor and the seat humidity value H_seat collected by the target seat humidity sensor. Based on the comparison results of the cabin ambient humidity value, seat humidity value and preset humidity threshold H_th, determine the second duration and the third duration.

[0183] The specific judgment logic is as follows:

[0184] a. H_hvac≤H_th and H_seat≤H_th→Normal mode, second duration = base duration Δt_hot, third duration = base duration Δt_cool;

[0185] b. If H_hvac > H_th or H_seat > H_th, then proceed to the humidity attribution branch:

[0186] i. If H_hvac > H_th but H_seat ≤ H_th, then the entire cabin is considered to be in high humidity.

[0187] ii. If H_hvac > H_th and H_seat > H_th, it is determined that the entire cabin is highly humid and there is localized liquid spillage on the seats;

[0188] iii. If H_hvac≤H_th and H_seat>H_th, it is determined to be localized liquid spillage on the seat.

[0189] When the entire cabin is under high humidity, the second duration = Δt_hot × K1 and the third duration = Δt_cool × K1; when spraying liquid in a localized area, the second duration = Δt_hot × K2 and the third duration = Δt_cool × K2.

[0190] When the two operating conditions are superimposed, max(K1,K2) is taken, and the coefficients are not multiplied. K1 and K2 are coefficients calculated based on a preset relationship. The control unit resamples H_hvac and H_seat every fixed period to dynamically correct the remaining second and third durations.

[0191] S207, The heating module of the target seat is controlled to heat the air drawn in by the ventilation module to the preset mite removal temperature T1 and maintain it for a second duration.

[0192] S208. After reaching the preset mite removal temperature T1, the ultraviolet sterilization module is activated to irradiate the airflow and the inner wall of the ventilation duct unit.

[0193] S209. When it is determined that the current temperature of the target seat is lower than the preset temperature threshold, the ventilation module in the target seat is controlled to perform a blowing operation, which continues for a third duration.

[0194] S210, The DHU interface prompts the user that the target seat self-cleaning process has been completed.

[0195] For example, it could display "The seat cleaning is complete, last cleaned XX hours ago." Furthermore, the DHU seat cleaning function switch could be turned off to give the user a clear sense of cleanliness.

[0196] Optionally, in some embodiments, the target seat can be pre-divided into a first region and a second region, wherein the first region is equipped with an air outlet and the second region is equipped with an air intake. Based on this, controlling the massage module deployed on the target seat to perform a massage operation in S12 can be specifically implemented as follows: while the ventilation module is blowing air onto the target seat, the massage module deployed in the first region of the target seat is controlled to perform a massage operation to drive dust particles on the surface of the target seat to the second region corresponding to the air intake of the ventilation module. After the massage module in the first region performs the massage operation, the massage module deployed in the second region is controlled to perform a massage operation.

[0197] It is important to understand that when the massage modules in both the first and second zones perform a massage operation, they are in the process of blowing air onto the target seat.

[0198] For example, the first region can be an area on the seat surface where dust particles are more likely to accumulate, such as the side of the seat cushion and the side of the backrest. In order to cause the dust particles to migrate directionally from the first region to the second region, the massage operation of the massage module in the first region is not performed arbitrarily, but is controlled according to a preset propagation direction and timing.

[0199] In one possible implementation, when the massage module in the first area is an airbag-type massage unit, the control device can control multiple partitioned airbags to inflate and deflate sequentially from the side furthest from the second area to the side closest to the second area, creating progressively advancing micro-undulations on the seat surface. These micro-undulations alter the surface contact state and local friction conditions, causing dust particles remaining on the surface to loosen and roll, slide, or jump along the direction of surface slope change, eventually converging towards the second area.

[0200] In another possible implementation, when the massage module in the first area is a vibrating massage unit, a high-frequency, low-amplitude initial vibration can be used to overcome the adhesion between dust particles and the surface, followed by low-frequency directional pulse vibration to create a displacement trend for the dust particles. For seats with obvious seams or surface textures, the vibration direction can be set relative to the seam direction to reduce the stagnation of dust particles at the seams.

[0201] In this step, the control device can further subdivide the first region based on a pre-stored seat area model. For example, the seat cushion area can be divided into a front edge area, a central support area, and a rear lumbar support adjacent area; the backrest area can be divided into a shoulder area, a lumbar area, and a side transition area. Then, based on the layout of the air intake in the seat, the target migration direction of dust particles is calculated or obtained by looking up a table, and the action sequence of the massage module in the first region is generated accordingly. For example, if the air intake is located in the middle and rear of the seat cushion, the massage module in the first region can first drive the front and middle areas of the seat cushion to gradually transmit deformation towards the rear. If the air intake is located in the middle of the backrest, the local massage units in the upper and lower parts of the backrest can converge towards the middle.

[0202] In some embodiments, the motion parameters can be set within a range suitable for dust particle migration without affecting the lifespan of the seat material. For example, the airbag's single inflation holding time can be set to 0.5 to 3 seconds, the vibration frequency can be set to 20 Hz to 150 Hz, and a single complete massage cleaning cycle can be set to 5 to 30 seconds. These parameter ranges allow dust particles to acquire sufficient loosening and displacement energy while avoiding excessive deformation that could lead to increased noise, seat surface fatigue, or excessive energy consumption.

[0203] The second area can be a seat surface area with fewer folds and gaps, which is suitable for the concentrated collection of dust particles, such as the middle of the seat cushion and the middle of the backrest.

[0204] In S13, the ventilation module controls the suction operation on the target seat. At this time, the air outlet in the first area stops blowing air, and the air intake in the second area starts working, drawing the dust particles that have gathered in the second area in S11 into the air duct. During the suction operation, the heating module can be activated simultaneously to heat the intake air to achieve deep drying and thermal mite removal.

[0205] Understandably, the structure of the massage module in the first area can be the same as or different from that of the massage module in the second area. When the massage module in the first area employs a larger-range loosening and dispersing strategy, the massage module in the second area can employ a smaller-amplitude, higher-precision gathering strategy to prevent dust particles from dispersing again in the second area.

[0206] In one possible implementation, the massage module in the second area can consist of multiple micro-airbag units arranged around the air intake. During the suction operation, the control device drives these airbags to undulate sequentially from the outside in, creating a deformation field on the surface of the second area that converges towards the air intake. Dust particles are gradually pushed towards the vicinity of the air intake during the deformation recovery process. For perforated fabrics or genuine leather surfaces, the massage module in the second area can also use short pulses to dislodge dust particles near the edges of the holes from their retention positions and allow them to enter the suction coverage area.

[0207] In another possible implementation, the massage module in the second area can employ vibration control at different frequencies. For example, a lower frequency can be used to slowly move larger dust particles or hair-like contaminants and prevent them from scattering, while a higher frequency can be used to apply vibration to finer dust particles, causing them to move away from the texture grooves and concentrate in a localized low-resistance area. In scenarios combining airbags and vibration, a slight surface slope can be created by squeezing with a short-stroke airbag, converging the particles towards the center, and then short-duration linear vibration can be used to increase the probability of dust particles approaching the air intake.

[0208] Furthermore, the duration and amplitude of the actions can be adjusted based on the actual dust particle carrying characteristics of the second area. For example, if the system detects a large amount of dust particles expected in the second area after the first area has finished removing them, the massage module in the second area can extend the duration of the actions to prevent the dust particles from remaining in a banded distribution before suction. When the friction coefficient of the seat surface is high, the pulse density can be increased or the action interval shortened to allow the dust particles multiple opportunities for displacement. When the second area is adjacent to seat gaps or edge transition areas, compensation actions can be added to the edge side units to prevent dust particles from accumulating at structural corners.

[0209] Figure 3 This is a timing diagram illustrating the vehicle seat self-cleaning method provided in an embodiment of this application. Figure 3 As shown, in the first stage (corresponding to S11), the ventilation module performs a blowing operation on the target seat. At this time, only the air outlet works, and the air intake does not work. The control device first controls the massage module of the first area to start the massage cycle of the first area. The airbag massage unit of the massage module of the first area sequentially completes the complete cycle of starting to expand outward, expanding to the highest point, starting to fall, and falling back to the initial state. Through periodic surface deformation, the dust particles on the surface and in the shallow filling layer of the first area are loosened. The loosened dust particles are blown up by the continuous airflow from the air outlet and gradually transported to the second area. After the massage cycle of the first area starts, the control device controls the massage module of the second area to start the massage cycle of the second area. The airbag massage unit of the massage module of the second area performs the same cycle. Through centripetal surface deformation, the dust particles that have been transported to the second area are further gathered above the air intake. After the first stage ends, the second stage (corresponding to S13) begins. The ventilation module switches to suction operation on the target seat. At this time, the suction port is working and the air outlet stops blowing air. Dust particles gathered in the second area are sucked into the air duct by the suction port, and after being intercepted and captured by the air filtration module, the cleaning is completed. The above two massage cycles can be repeated multiple times depending on the actual degree of pollution of the target seat.

[0210] It should be understood that the massage cycle of the first area begins earlier than the massage cycle of the second area.

[0211] Figure 4This is a schematic diagram showing the positions of the air outlet and air intake of the target seat provided in an embodiment of this application. Figure 4 As shown, each sub-massage module of the target seat is an airbag-type massage unit. The air intake is located in the middle area of ​​the seat cushion and the middle area of ​​the backrest of the target seat, and the air outlet is located in the side area of ​​the seat cushion and the side area of ​​the backrest of the target seat.

Figure 5 As shown, the side area of ​​the seat cushion and the side area of ​​the backrest of the target seat can be defined as the first area, and the middle area of ​​the seat cushion and the middle area of ​​the backrest of the target seat can be defined as the second area.

[0230] If the humidity value of the cabin environment is not greater than the preset humidity threshold, and the humidity value of the seat is greater than the preset humidity threshold, then the value obtained by multiplying the second preset duration coefficient corresponding to the seat humidity value in the third mapping relationship by the preset duration is determined as the second duration.

[0231] If the humidity value of the cabin environment is greater than the preset humidity threshold, and the humidity value of the seat is greater than the preset humidity threshold, then the value obtained by multiplying the maximum value of the first preset duration coefficient and the second preset duration coefficient by the preset duration is determined as the second duration.
