[0055] To better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application are detailed descriptions of the technical solutions of the embodiments of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0056] Please refer to Figure 1 , a vehicle seat ventilation system with multiple control methods provided by an embodiment of the present invention. The system includes: a seat ventilation controller, a temperature sensor, a pressure sensor, a seat ventilation module, and an in-vehicle air conditioning module. Among them, the seat ventilation controller is communicatively connected to the temperature sensor, the pressure sensor, the seat ventilation module, and the in-vehicle air conditioning module, and is used to obtain the temperature data obtained by the temperature sensor and the pressure data obtained by the pressure sensor, calculate the fan speeds corresponding to the seat ventilation module and the in-vehicle air conditioning module respectively according to the temperature data and the pressure data, and control the operation of the seat ventilation module and the in-vehicle air conditioning module based on the calculated fan speeds, so as to improve the intelligence and effectiveness of vehicle seat ventilation through the present application.

[0057] It should be noted that this embodiment includes multiple temperature sensors and multiple pressure sensors. For example, a temperature sensor set outside the vehicle is used to obtain the outside temperature; a temperature sensor set inside the vehicle is used to obtain the inside temperature; a temperature sensor set on the seat is used by the user to obtain the temperature of the seat surface. The pressure sensor is set on multiple seats, and multiple pressure sensors can be set under the seat or on the seat back of each seat to obtain the sitting posture of the user through the pressure sensor, thereby realizing the intelligent control of the seat ventilation module.

[0058] A vehicle seat ventilation system with multiple control methods provided by this embodiment, when the vehicle is started and the vehicle air conditioner is triggered to start, determines the fan speeds in the in-vehicle air conditioning module and the seat ventilation module through the obtained temperature data and pressure data, and then controls the operation of the in-vehicle air conditioning module according to the fan speed in the in-vehicle air conditioning module, and controls the operation of the target fan in the seat ventilation module according to the fan speed in the seat ventilation module. Thus, the automatic opening of the seat ventilation is realized through the present application, and the automatic adjustment and control can be performed based on the temperature data without manual adjustment. Therefore, the intelligence and effectiveness of vehicle seat ventilation can be improved through the present application.

[0059] Specifically, as Figure 2 shown, this embodiment provides a vehicle seat ventilation method with multiple control methods. This method is applied to the seat ventilation controller in the above vehicle seat ventilation system with multiple control methods. The execution steps of this method are as follows:

[0060] 201. When the vehicle starts and the vehicle air conditioner is triggered to start, obtain the in-vehicle temperature and the out-of-vehicle temperature through a temperature sensor, and obtain the pressure data of the seat and the seat back through a pressure sensor.

[0061] Specifically, in this embodiment, the out-of-vehicle temperature can be obtained through a temperature sensor arranged outside the vehicle, and the in-vehicle temperature can be obtained through a temperature sensor arranged inside the vehicle. The pressure data of the seat can be obtained through a pressure sensor arranged at the bottom of the seat, and the pressure data of the seat back can be obtained through a pressure sensor arranged on the seat back.

[0062] 202. Determine the position areas where the user contacts the seat and the seat back based on the pressure data of the seat and the seat back.

[0063] In an alternative embodiment provided by the present application, the step of determining the position areas where the user contacts the seat and the seat back based on the pressure data of the seat and the seat back includes: determining the sitting points of the positions where the user contacts the seat and the seat back based on the pressure data of the seat and the seat back, matching the position coordinate points with the models of the seat and the seat back to determine the matching position coordinate points, performing clustering calculation on the matching position coordinate points, and determining the position areas where the user contacts the seat and the seat back according to the results.

[0064] Among them, the models of the seat and the seat back are the simulation structure diagrams of the seat and the seat back. Loading the position coordinate points into the simulation structure diagrams, the matching position coordinate points in the simulation structure diagrams are determined, and then clustering calculation is performed on the matching position coordinate points to obtain the position areas where the user contacts the seat and the seat back. For example, when the user is in the driver's seat, the sitting posture is that the buttocks contact the seat and the back contacts the lower part of the seat back, that is, the contact position areas are the seat and the lower part of the seat back.

[0065] 203. Obtain other position areas of the seat and the seat back except the position areas.

[0066] Specifically, in this embodiment, based on the simulation structure diagrams mentioned in the previous step, other position areas except the position areas can be determined. If the contact areas are directly above the seat and the lower part of the seat back, then other position areas can be the upper part of the seat back, directly below the seat, in front of the seat, behind the seat, the back of the seat back, etc. This embodiment does not make specific limitations on this.

[0067] 204. Determine the target fans that need to work in the seat ventilation module according to the other position areas.

[0068] Among them, a plurality of fans are arranged inside the seat and the seat back in the seat ventilation module, and different fans correspond to different position areas. In this embodiment, the seat and the seat back can be divided into a plurality of position areas, such as the seat center area, the seat peripheral area, the upper part area of the seat back, and the lower part area of the seat back, and one fan or a plurality of fans are correspondingly arranged in each area.

[0069] Specifically, determining the target fan that needs to work in the seat ventilation module according to the other position areas includes: matching the other position areas with the models of the seat and the seat back, and determining the fans in the matching results as the target fans that need to work in the seat ventilation module. For example, if the other position areas are the seat peripheral area and the upper part area of the seat, the target fans that need to work can be the fans built in the upper part area of the seat and the seat peripheral area.

[0070] It should be noted that the working principle of the ventilated seat is to add fans in the seat cushion and the backrest. These fans inhale air and then introduce it into the ventilation layer, and the air flow then penetrates upward from the surface of the ventilation layer, passes through the heating pad and flows to the surface of the seat cover. Since the seat cover uses perforated leather, air can flow out from the small holes on the seat surface, realizing the ventilation function, enabling the occupant to disperse the sweat on the buttocks and back in hot weather and bringing comfort. Since the user sitting on the car seat will inevitably affect the inhalation of air by the fans in the seat and the seat back, and turning on all the fans in the seat and the seat back will generate a large amount of noise and sometimes cause waste of resources. Therefore, in this embodiment, the target fans that need to work in the seat ventilation module are determined according to the user's sitting posture (i.e., pressure data), and then the target fans work to smoothly inhale and introduce air into the circulation layer, so as to realize the ventilation of the car seat while reducing the noise caused by the operation of multiple fans.

[0071] 205. Obtain the temperature difference between the in-vehicle temperature and the out-vehicle temperature, calculate the fan speed in the vehicle air-conditioning module according to the in-vehicle temperature, the temperature difference and the preset temperature range, and calculate the fan speed in the seat ventilation module according to the in-vehicle temperature, the temperature difference and the preset temperature range.

[0072] In an alternative embodiment provided by the present application, calculating the fan speed in the vehicle air-conditioning module according to the in-vehicle temperature, the temperature difference and the preset temperature range includes:

[0073] 2051. Determine the current working mode of the vehicle air-conditioning module according to the out-vehicle temperature, and the working mode includes a refrigeration mode and a heating mode.

[0074] In this embodiment, the first temperature and the second temperature can be set. If the outside temperature is higher than the first temperature, the cooling mode is turned on; if the outside temperature is between the first temperature and the second temperature, the operation of the vehicle-mounted air-conditioning module can be stopped; if the outside temperature is lower than the second temperature, the heating mode is turned on.

[0075] 2052. If the current working mode is the heating mode, the fan speed in the vehicle-mounted air-conditioning module is calculated according to the lowest value in the preset temperature range, the vehicle interior temperature, and the temperature difference.

[0076] Specifically, calculating the fan speed in the vehicle-mounted air-conditioning module according to the lowest value in the preset temperature range, the vehicle interior temperature, and the temperature difference includes: according to the formula Calculate the fan speed in the vehicle-mounted air-conditioning module in the cooling mode; where is the vehicle interior temperature, is the lowest value in the preset temperature range, is the temperature difference, is the fitting coefficient, specifically can be 0.8, 0.5. Among them, the preset temperature range is the temperature at which the human body feels comfortable. For example, the preset temperature range is 20-24 degrees Celsius.

[0077] Correspondingly, controlling the operation of the vehicle-mounted air-conditioning module according to the fan speed in the vehicle-mounted air-conditioning module includes: if the temperature difference is positive, controlling the vehicle-mounted air-conditioning module to perform internal circulation heating according to the fan speed in the vehicle-mounted air-conditioning module; if the temperature difference is negative, controlling the vehicle-mounted air-conditioning module to perform external circulation heating according to the fan speed in the vehicle-mounted air-conditioning module.

[0078] It should be noted that if the current working mode is the heating mode and the temperature difference is positive, it means that the vehicle interior temperature is higher than the outside temperature. At this time, controlling the vehicle-mounted air-conditioning module to perform internal circulation heating according to the fan speed in the vehicle-mounted air-conditioning module can quickly achieve heating; if the current working mode is the heating mode and the temperature difference is negative, it means that the vehicle interior temperature is lower than the outside temperature. At this time, controlling the vehicle-mounted air-conditioning module to perform external circulation heating according to the fan speed in the vehicle-mounted air-conditioning module can quickly achieve heating.

[0079] 2053. If the current working mode is the cooling mode, the fan speed in the vehicle-mounted air-conditioning module is calculated according to the highest value in the preset temperature range, the vehicle interior temperature, and the temperature difference.

[0080] Specifically, calculating the fan speed in the vehicle-mounted air-conditioning module according to the highest value in the preset temperature range, the vehicle interior temperature, and the temperature difference includes: according to the formula Calculate the fan speed in the vehicle air - conditioning module; wherein, is the vehicle interior temperature, is the maximum value in the preset temperature range, is the temperature difference, is the fitting coefficient, Specifically, it can be 0.7, 0.6; correspondingly, controlling the operation of the vehicle air - conditioning module according to the fan speed in the vehicle air - conditioning module includes: if the temperature difference is positive, controlling the vehicle air - conditioning module for external - circulation refrigeration according to the fan speed in the vehicle air - conditioning module; if the temperature difference is negative, controlling the vehicle air - conditioning module for internal - circulation refrigeration according to the fan speed in the vehicle air - conditioning module.

[0082] Specifically, determining the fan speeds of each target fan in the seat ventilation module according to the number and positions of the target fans, and the vehicle interior temperature, the temperature difference, and the preset temperature range includes: calculating the initial fan speed of the fans in the seat ventilation module according to the vehicle interior temperature, the temperature difference, and the preset temperature range; determining the average speed of each target fan according to the initial fan speed of the fans in the seat ventilation module and the number of the target fans; revising the average speed of the target fans by the maximum fan speed corresponding to the position of the target fans obtained through a preset mapping table to obtain the fan speed corresponding to each target fan.

[0083] Wherein, calculating the initial fan speed of the fans in the seat ventilation module according to the vehicle interior temperature, the temperature difference, and the preset temperature range includes: calculating the maximum temperature difference between the vehicle interior temperature and the preset temperature range; if the maximum temperature difference is greater than a target value, which is a constant value set according to actual requirements, then calculating the initial fan speed of the fans in the seat ventilation module according to the vehicle interior temperature and the seat surface temperature; if the maximum temperature difference is less than or equal to the target value, then calculating the initial fan speed of the fans in the seat ventilation module according to the vehicle interior temperature and the temperature difference.
