Description

Technical Field

[0001] The invention relates to the technical field of ventilation control, and in particular to an automatic control method for seat ventilation. Background Art

[0002] With the development of the automobile industry and the increase in consumer demand, seat comfort has become one of the important considerations when buying a car. The seat ventilation function can significantly reduce the temperature of the seat surface and reduce the stuffiness and discomfort caused by long-term riding. At the same time, in a high temperature environment, the seats are prone to accumulate heat and moisture, increasing the possibility of passengers sweating. The seat ventilation function can effectively reduce sweat accumulation, keep the seats dry, reduce bacterial growth, and is beneficial to the health of passengers.

[0003] Prior art, such as the invention patent application with announcement number CN111409522A, discloses a seat ventilation automatic control method, the method comprising: when the automatic mode of the air conditioner is turned on inside the vehicle, obtaining the vehicle's external temperature, the vehicle's internal temperature and the vehicle's air conditioning temperature; automatically controlling the opening of the seat's ventilation function and the adjustment of the ventilation gear according to the relationship between the vehicle's external temperature and the vehicle's internal temperature and the vehicle's air conditioning temperature. The present invention also provides a seat ventilation automatic control system. The present invention can automatically control the opening of the seat ventilation function and the adjustment of the gear according to the vehicle's external temperature, the vehicle's internal temperature and the air conditioning temperature set by the driver, which can reduce the complexity of the driver's operation and improve safety and comfort.

[0004] With respect to the above scheme, the present invention finds that the above technology has at least the following technical problems: 1. The above scheme controls seat ventilation by identifying the seat temperature. Ventilation will not only affect the user's temperature sensation, but also the humidity sensation and the sense of smell. The above scheme does not identify the seat humidity and the seat ventilation gas to control the seat ventilation device. The analysis result is inaccurate, which reduces the user's experience. At the same time, the above scheme does not specify whether the ventilation is controlled by air supply or air suction, and does not control the ventilation method, which reduces the user's comfort.

[0005] 2. The above scheme treats the seat as a whole, but the seat is ventilated through various vents. The above scheme does not control the vent switches, and ventilation is performed at unnecessary vents, resulting in increased ventilation costs. At the same time, the above scheme does not control the ventilation fan and the size of the vents, which increases the ventilation cost and reduces the ventilation experience. Summary of the invention

[0006] In view of the above-mentioned technical deficiencies, an object of the present invention is to provide a method for automatically controlling seat ventilation.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a seat ventilation automatic control method, comprising the following steps: Ventilation positioning setting: collecting seat cushion pressure data and backrest pressure data, analyzing the seat cushion pressure data and backrest pressure data, obtaining the pressure index of each seat cushion ventilation area and each backrest pressure area, and then setting the ventilation positioning scheme according to the pressure index of each seat cushion ventilation area and each backrest pressure area.

[0008] Temperature and ventilation settings: collect the car's temperature data, humidity data, and gas data, and set the seat temperature ventilation plan, seat humidity ventilation plan, and seat gas ventilation plan respectively according to the car's temperature data, humidity data, and gas data.

[0009] Driving ventilation settings: Collect the user's current driving data, analyze the user's current driving data, obtain the current driving status, and then set the driving ventilation plan.

[0010] Preferably, the ventilation positioning scheme is specifically set up as follows: the number of usage judgments of each seat cushion ventilation area within the preset number of collections after each historical collection in the database is the number of seat cushion usage areas, and each seat cushion ventilation area whose number of usage judgments is greater than the preset number of usage judgments is recorded as each standard seat cushion ventilation area, thereby obtaining each standard seat cushion ventilation area used in each historical collection.

[0011] The initial state and pressure index of each standard seat cushion ventilation area collected historically are obtained from the database. If the initial state of a standard seat cushion ventilation area collected historically is a use state, the standard seat cushion ventilation area is recorded as the standard seat cushion ventilation area, thereby obtaining each standard seat cushion ventilation area. The maximum and minimum values ​​of the pressure index in each standard seat cushion ventilation area are respectively recorded as the upper and lower limits of the standard use area pressure index range, thereby obtaining the standard use area pressure index range. The standard use area pressure index range is analyzed according to the analysis method of the standard use area pressure index range to obtain the standard unused area pressure index range.

[0012] If a seat cushion ventilation area is a seat cushion area currently in use, and the pressure index of the seat cushion ventilation area belongs to the standard pressure index interval of seat cushion ventilation areas in use, it indicates that the seat cushion ventilation area is an area that needs ventilation; if a seat cushion ventilation area is a seat cushion area that is not currently in use, and the pressure index of the seat cushion ventilation area belongs to the standard pressure index interval of unused areas, it indicates that the seat cushion ventilation area is an area that needs ventilation, thereby obtaining each seat cushion area that needs ventilation, and analyzing by the analysis method of each seat cushion area that needs ventilation, obtaining each seat armrest area that needs ventilation.

[0013] The ventilation positioning plan is to ventilate each seat area that needs ventilation and close other ventilation openings.

[0014] The beneficial effects of the present invention are: 1. The present invention first collects and analyzes the pressure data of the seat, and analyzes the pressure index of each ventilation area based on this, and then determines whether each ventilation area is ventilated based on the pressure index. At the same time, according to the temperature, humidity and gas data, the seat temperature ventilation plan, seat humidity ventilation plan and seat gas ventilation plan are automatically set. Finally, the air flow and flow rate are changed according to the user's driving data. The automatic seat ventilation control method of the present invention controls the seat ventilation by changing the vent area and the fan efficiency, while improving the user's comfort and reducing the ventilation cost. The present invention controls the temperature, humidity and direction of the ventilation air through temperature, humidity and gas data, which better meets user needs and improves user satisfaction.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] according to Figure 1 As shown, the present invention provides a seat ventilation automatic control method, comprising the following steps: ventilation positioning setting: collecting seat cushion pressure data and backrest pressure data, analyzing the seat cushion pressure data and backrest pressure data, obtaining pressure indexes of each seat cushion ventilation area and each backrest pressure area, and then setting a ventilation positioning scheme according to the pressure indexes of each seat cushion ventilation area and each backrest pressure area.

[0019] In a specific embodiment, the seat cushion pressure data and the backrest pressure data are collected, and the specific collection process is as follows: the seat cushion pressure data includes the current pressure and historical pressures of each seat cushion ventilation area, and the backrest pressure data includes the current pressure and historical pressures of each backrest ventilation area.

[0020] Pressure sensors are arranged under the seat cushions and backrest cushions corresponding to the seat vents to collect the pressures of each seat cushion ventilation area and backrest ventilation area. The pressures of each seat cushion ventilation area collected each time within a preset time are counted to obtain the pressures of each seat cushion ventilation area collected each time within the preset time, from which the current pressure and historical pressures of each seat cushion ventilation area are obtained. The pressures of each seat cushion ventilation area collected each time within the preset time are summarized to obtain the current pressure and historical pressures of each seat cushion ventilation area.

[0021] It should be noted that a circle is drawn with the center of the vent as the center and the preset vent influence distance as the radius to obtain the influence area of ​​each vent, and the influence area of ​​each vent is recorded as the ventilation area of ​​each seat cushion.

[0023] If the current pressure of a seat cushion ventilation area belongs to the seat cushion usage pressure range, the seat cushion ventilation area is recorded as the currently used seat cushion area. If the current pressure of a seat cushion ventilation area does not belong to the seat cushion usage pressure range, the seat cushion ventilation area is recorded as the currently unused seat cushion area.

[0024] If a historical pressure of a currently used seat cushion area belongs to the seat cushion unused pressure interval, it means that the currently used seat cushion area was an unused seat cushion area at the historical collection time point, and the historical number of unused times of the currently used seat cushion area is obtained by statistics; if a historical pressure of a currently used seat cushion area does not belong to the seat cushion unused pressure interval and does not belong to the seat cushion used pressure interval, it means that the currently used seat cushion area was an abnormally used seat cushion area at the historical collection time point, and the historical number of abnormal uses of the currently used seat cushion area is obtained by statistics, so as to obtain the historical number of unused times and the historical number of abnormal uses of each currently used seat cushion area, and analyze the pressure index of each seat cushion ventilation area by the analysis method, and obtain the pressure index of each seat armrest pressure data.

[0025] It should be noted that abnormal use means that the seat cushion area senses external pressure, but the pressure is not directly applied by the user, such as seat cushion deformation caused by sitting posture or pressure applied by heavy objects.

[0026] The historical unused times of each currently used seat cushion area and historical abnormal usage times Substitute into the pressure index calculation formula In the example above, we can get the pressure index of the current seat cushion area a. , a is the number of the seat area currently in use, , , and The standard unused times and the standard abnormal used times of the currently used seat cushion area are respectively preset. and The weight factor of the number of times the seat cushion area is not used and the weight factor of abnormal use are respectively, , , , the historical unused times of each currently unused seat cushion area and historical abnormal usage times Substitute into the pressure index calculation formula Get the pressure index of the currently unused seat area , b is the number of the currently unused seat area, , , and are respectively the standard unused times and the standard abnormal used times of the preset currently unused seat cushion area, and The weight factor of the number of times the currently unused seat area is not used and the weight factor of abnormal use are respectively preset, , , The pressure index of the currently used seat cushion area and the pressure index of the currently unused seat cushion area are summed up to obtain the pressure index of each seat cushion ventilation area, and the historical unused times of each currently used seat cushion area are summed up to obtain the pressure index of each seat cushion ventilation area. and historical abnormal usage times Substitute into the pressure index calculation formula , get the pressure index of the current use of the chair area d , d is the number of the current seat area, , , and The standard unused times and the standard abnormal used times of the currently used seat area are respectively preset. and The weight factor of the number of times the preset seat area is not used and the weight factor of abnormal use are respectively, , , , the historical unused times of each currently unused chair area and historical abnormal usage times Substitute into the pressure index calculation formula Get the pressure index of the currently unused chair area , e is the number of the currently unused seat area, , , and are respectively the standard unused times and the standard abnormal used times of the preset currently unused chair area. and The weight factors of the number of unused times and the weight factors of abnormal use of the preset currently unused chair area are respectively, , , , the pressure index of the currently used seat area and the pressure index of the currently unused seat area are summed up to obtain the pressure index of each seat ventilation area.

[0027] It should be noted that the standard unused times and the standard abnormal used times of the currently used seat cushion area are set by the staff. For example, the standard unused times and the standard abnormal used times of the currently used seat cushion area are 10 times and 12 times respectively. The standard unused times of the currently unused seat cushion area, the standard abnormal used times of the currently unused seat cushion area, the standard unused times of the currently used armchair area, the standard abnormal used times of the currently used armchair area, the standard unused times of the currently unused armchair area and the standard abnormal used times of the currently unused armchair area are all set by the staff. At the same time, the average of each unused times and each abnormal used times of the currently used seat cushion area in each historical record in the database is calculated to obtain the average unused times of the currently used seat cushion area. and average number of abnormal usage , , ,For example, , , calculate the average of each unused times and each abnormal use times of the currently unused seat cushion area in each historical record in the database, and obtain the average unused times of the currently unused seat cushion area and average number of abnormal usage , , ,For example, , , calculate the average of each unused times and each abnormal use times of the currently used chair area in each historical record in the database, and get the average unused times of the currently used chair area and average number of abnormal usage , , ,For example, , , calculate the average of each unused times and each abnormal use times of the currently unused chair area in each historical record in the database, and obtain the average unused times of the currently unused chair area and average number of abnormal usage , , ,For example, , .

[0028] In a specific embodiment, the ventilation positioning scheme is set up, and the specific setting method is as follows: the usage judgment number of each seat cushion ventilation area within the preset collection number after each historical collection in the database is the usage judgment number of the seat cushion area, and each seat cushion ventilation area with a usage judgment number greater than the preset usage judgment number is recorded as a standard usage seat cushion ventilation area, so as to obtain the standard usage seat cushion ventilation area of ​​each historical collection.

[0029] The initial state and pressure index of each standard seat cushion ventilation area collected historically are obtained from the database. If the initial state of a standard seat cushion ventilation area collected historically is a use state, the standard seat cushion ventilation area is recorded as the standard seat cushion ventilation area, thereby obtaining each standard seat cushion ventilation area. The maximum and minimum values ​​of the pressure index in each standard seat cushion ventilation area are respectively recorded as the upper and lower limits of the standard use area pressure index range, thereby obtaining the standard use area pressure index range.

[0030] The initial state and pressure index of each standard seat cushion ventilation area collected historically are obtained from the database. If the initial state of a standard seat cushion ventilation area collected historically is an unused state, the standard seat cushion ventilation area is recorded as a standard unused seat cushion ventilation area, thereby obtaining each standard seat cushion ventilation area. The maximum and minimum values ​​of the pressure index in each standard unused seat cushion ventilation area are respectively recorded as the upper and lower limits of the standard unused area pressure index range, thereby obtaining the standard unused area pressure index range.

[0031] The number of times each chair ventilation area is judged as the use chair area within the preset number of collections after each historical collection in the database, and each chair ventilation area whose use judgment number is greater than the preset number of use judgments is recorded as a standard use chair ventilation area, so as to obtain the standard use chair ventilation area of ​​each historical collection.

[0032] The initial state and pressure index of each standard use seat ventilation zone of each historical collection are obtained from the database. If the initial state of a standard use seat ventilation zone of a certain historical collection is the use state, then the standard use seat ventilation zone is recorded as the standard use seat ventilation area, thereby obtaining each standard use seat ventilation area, and the maximum and minimum values ​​of the pressure index in each standard use seat ventilation area are respectively recorded as the upper and lower limits of the standard use area pressure index range, thereby obtaining the standard use area pressure index range.

[0033] The initial state and pressure index of each standard seat ventilation area collected historically are obtained from the database. If the initial state of a standard seat ventilation area collected historically is unused, the standard seat ventilation area is recorded as the standard unused seat ventilation area, thereby obtaining each standard seat ventilation area. The maximum and minimum values ​​of the pressure index in each standard unused seat ventilation area are respectively recorded as the upper and lower limits of the standard unused area pressure index range, thereby obtaining the standard unused area pressure index range.

[0034] If a seat cushion ventilation area is a seat cushion area currently in use, and the pressure index of the seat cushion ventilation area belongs to the standard pressure index interval of seat cushion ventilation areas in use, it indicates that the seat cushion ventilation area is an area that needs ventilation; if a seat cushion ventilation area is a seat cushion area that is not currently in use, and the pressure index of the seat cushion ventilation area belongs to the standard pressure index interval of unused areas, it indicates that the seat cushion ventilation area is an area that needs ventilation, thereby obtaining each seat cushion area that needs ventilation.

[0035] If a certain seat ventilation area is a seat area currently in use, and the pressure index of the seat ventilation area belongs to the standard pressure index interval of seat ventilation areas in use, it indicates that the seat ventilation area is an area that needs ventilation; if a certain seat ventilation area is a seat area that is not currently in use, and the pressure index of the seat ventilation area belongs to the standard pressure index interval of unused areas, it indicates that the seat ventilation area is an area that needs ventilation, thereby obtaining each seat area that needs ventilation.

[0036] The ventilation positioning plan is to ventilate each seat cushion area and each seat backrest area that needs ventilation, and close other ventilation openings.

[0037] It should be noted that when the vent is closed, the fan corresponding to the vent is closed. At the same time, the pressure index is divided into a standard seat cushion ventilation area pressure index interval and a non-standard seat cushion ventilation area pressure index interval. It can also be divided into a first seat cushion ventilation area pressure index interval, a second seat cushion ventilation area pressure index interval... the hth seat cushion ventilation area pressure index interval, where h is the maximum number of the seat cushion ventilation area pressure index intervals. The numbering of the pressure index intervals of the seat cushion ventilation area is arranged in descending order according to the lower limit of each interval. The ventilation rate of the first pressure index interval of the seat cushion ventilation area is 0, and the ventilation rate of the hth pressure index interval of the seat cushion ventilation area is 1. Between the first seat cushion ventilation area to the hth seat cushion ventilation area, the ventilation rate of the pressure index interval of the seat cushion ventilation area gradually increases in descending order from the interval number. The ventilation rate is the ventilation time per unit time. When the ventilation rate is 0, the ventilation time is 0. When the ventilation rate is 1, it means that ventilation is always on.

[0038] Temperature and ventilation settings: collect the car's temperature data, humidity data, and gas data, and set the seat temperature ventilation plan, seat humidity ventilation plan, and seat gas ventilation plan respectively according to the car's temperature data, humidity data, and gas data.

[0039] In a specific embodiment, the temperature data, humidity data and gas data of the car are collected, and the specific collection process is as follows: the temperature data of the car includes the current seat cushion temperature, the current backrest temperature, the current temperature inside the car and the current temperature outside the car; the humidity data of the car includes the current humidity inside the car, the current humidity outside the car, the current seat cushion humidity and the current backrest humidity; the gas data of the car includes the current concentration of each gas in the seat, the current concentration of each gas in the car and the current concentration of each gas outside the car.

[0040] Temperature sensors are arranged below the vents of the car seats, inside and outside the car, and the air temperature is collected through the temperature sensors to obtain the temperature data of the car. Humidity sensors are arranged below the vents of the car seats, inside and outside the car, and the humidity data of the car is obtained. Gas sensors are arranged below the vents of the car seats, inside and outside the car, and the gas data of the car is obtained.

[0041] In a specific embodiment, the seat temperature ventilation scheme is set, and the specific setting process is as follows: the number of occurrences of each seat cushion temperature at each in-car temperature is obtained from the database, and each seat cushion temperature whose number of occurrences at each in-car temperature is greater than the preset number of occurrences is recorded as a standard seat cushion temperature, thereby obtaining the standard seat cushion temperature for each in-car temperature, and the maximum and minimum values ​​of the standard seat cushion temperature for each in-car temperature are recorded as the upper and lower limits of the standard seat cushion temperature range, thereby obtaining the standard seat cushion temperature range for each in-car temperature, and then obtaining the standard seat cushion temperature range for the current in-car temperature.

[0042] If the current seat cushion temperature does not belong to the standard seat cushion temperature range of the current vehicle interior temperature, seat cushion temperature ventilation is performed; if the current seat cushion temperature is greater than the upper limit of the standard seat cushion temperature range of the current vehicle interior temperature, low-temperature seat cushion ventilation is performed, and the air temperature of low-temperature ventilation is obtained from the database. The current seat cushion temperature is subtracted from the low-temperature ventilation air temperature to obtain the abnormal seat cushion temperature difference; if the current seat cushion temperature is less than the lower limit of the standard seat cushion temperature range of the current vehicle interior temperature, high-temperature seat cushion ventilation is performed, and the high-temperature ventilation temperature is obtained from the database. The current seat cushion temperature is subtracted from the high-temperature ventilation temperature to obtain the abnormal seat cushion temperature difference; when the abnormal seat cushion temperature difference is greater than the preset temperature difference, the air supply ventilation mode is performed; when the abnormal seat cushion temperature difference is less than or equal to the preset temperature difference, the air suction ventilation mode is performed, thereby obtaining the seat cushion temperature ventilation plan, and setting the seat cushion temperature ventilation plan using the method for setting the seat cushion temperature ventilation plan.

[0043] It should be noted that the method divides the seat into two parts, namely, a seat cushion and an armrest, and the seat temperature ventilation scheme includes a seat cushion temperature ventilation scheme and an armrest temperature ventilation scheme.

[0044] Air supply is a mode that outputs air from the seat to the user, increasing the air pressure inside the seat, which can quickly change the temperature. However, long-term blowing of air affects your health. Air suction is a mode that outputs air from the car to the user, and finally the air enters the seat. The air pressure is reduced by the fan inside the seat, which can enhance user comfort.

[0045] In a specific embodiment, the seat humidity ventilation scheme is set up, and the specific setting process is as follows: the maximum humidity and minimum humidity of each normal seat cushion in the database are recorded as the upper limit and lower limit of the standard seat cushion humidity range, respectively, to obtain the standard seat cushion humidity range, if the current seat cushion humidity does not belong to the standard seat cushion humidity range, the seat cushion humidity ventilation is performed.

[0046] If the current humidity inside the car belongs to the standard seat cushion humidity range, the seat cushion ventilation mode of suction is implemented; if the current humidity inside the car does not belong to the standard seat cushion humidity range, and the current outdoor humidity belongs to the standard seat cushion humidity range, the external air supply vents are opened, and the seat cushion ventilation mode of air supply is implemented; if the current humidity inside the car does not belong to the standard seat cushion humidity range, and the current outdoor humidity does not belong to the standard seat cushion humidity range, the seat cushion ventilation mode of humidity control and air supply is implemented, so as to obtain the seat cushion humidity ventilation plan, and set the seat cushion humidity ventilation plan according to the setting method of the seat cushion humidity ventilation plan.

[0047] It should be noted that the seat humidity ventilation plan includes the seat cushion humidity ventilation plan and the backrest humidity ventilation plan.

[0048] In a specific embodiment, the seat gas ventilation scheme is set up, and the specific setting process is as follows: the minimum value of each gas concentration in normal air is recorded as the standard concentration of each gas; if the current seat cushion gas concentration is greater than the standard concentration of the gas, and the current gas concentration in the vehicle is less than or equal to the standard concentration of the gas, a suction seat cushion ventilation mode is performed; if the current seat cushion gas concentration is greater than the standard concentration of the gas, and the current gas concentration in the vehicle is greater than the standard concentration of the gas, a supply seat cushion ventilation mode is performed; if the current outdoor gas concentration is greater than the standard concentration of the gas, and the outside air supply port is in an open state, the outside air supply port is closed, thereby obtaining the seat cushion gas ventilation scheme; and the gas humidity ventilation scheme is set using the method for setting the seat cushion gas ventilation scheme.

[0049] It should be noted that the seat gas ventilation plan includes the seat cushion gas ventilation plan and the backrest gas ventilation plan. If the modes conflict, the temperature ventilation plan will be carried out first, then the humidity ventilation plan, and finally the gas ventilation plan. For example, when the temperature ventilation plan requires an air suction ventilation mode, and the humidity ventilation plan requires an air supply ventilation mode, the temperature ventilation plan will be carried out first, and when the temperature reaches normal, the humidity ventilation plan will be carried out.

[0050] Driving ventilation settings: Collect the user's current driving data, analyze the user's current driving data, obtain the current driving status, and then set the driving ventilation plan.

[0051] In a specific embodiment, the user's current driving data is analyzed, and the specific analysis process is as follows: the user's current driving data is the current driving speed, the current driving duration and the current driving distance, and the driving speed interval, driving duration interval and driving distance interval of each driving state are obtained from the database. If the current driving speed, the current driving duration and the current driving distance all belong to the driving speed interval, driving duration interval and driving distance interval of a certain driving state, it indicates that the current driving state is that driving state.

[0052] It should be noted that in driving conditions such as long-term high-speed driving, urban traffic jams or country roads, when the driving condition is long-term high-speed driving in summer, the wind speed is increased and the air flow is increased to reduce the driver's drowsiness.

[0053] The specific setting process of setting the driving ventilation plan is as follows: obtaining the preset suction wind speed, preset suction air flow, preset blowing wind speed and preset blowing air flow corresponding to each driving state from the database, and obtaining the current preset suction wind speed, current preset suction air flow, current preset blowing wind speed and current preset blowing air flow according to the current driving state.

[0054] If the current ventilation state is suction, and the current ventilation wind speed is less than the current preset wind speed for suction, then increase the power of the current blowing fan until the current ventilation wind speed is equal to the current preset wind speed for suction; if the current ventilation state is suction, and the current suction air flow rate is less than the preset suction air flow rate, then increase the ventilation area of ​​the current vent until the current suction air flow rate is equal to the preset suction air flow rate, thereby obtaining the ventilation plan for suction, and set the ventilation plan for blowing according to the setting method of the suction ventilation plan.

[0055] It should be noted that the vehicle ventilation plan includes a suction ventilation plan and a blowing ventilation plan.

[0056] The current power of the blowing fan, the current suction air flow rate, the current power of the suction fan and the current power of the suction fan are obtained from the database.

[0057] The above contents are merely examples and explanations of the concept of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined in this specification, they shall all fall within the protection scope of the present invention.
