It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0018] See also Figure 1 , a car seat ventilation system with multiple control modes 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 a vehicle air conditioning module. The seat ventilation controller is in communication with the temperature sensor, the pressure sensor, the seat ventilation module, and the vehicle air conditioning module, and is used to obtain temperature data obtained by the temperature sensor and pressure data obtained by the pressure sensor, and calculate the fan speeds corresponding to the seat ventilation module and the 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 vehicle air conditioning module based on the calculated fan speed, so that the intelligence and effectiveness of car seat ventilation can be improved through this application.

[0019] It should be noted that the present embodiment includes multiple temperature sensors and multiple pressure sensors. For example, the temperature sensor set outside the vehicle is used to obtain the temperature outside the vehicle; the temperature sensor set inside the vehicle is used to obtain the temperature inside the vehicle; the temperature sensor set on the seat is used for the user to obtain the temperature of the seat surface. The pressure sensor is set on multiple seats, and each seat can be provided with multiple pressure sensors under the seat or at the seat back, so as to obtain the user's sitting posture through the pressure sensor, thereby realizing the intelligent control of the seat ventilation module.

[0020] The present embodiment provides a car seat ventilation system with multiple control modes. When the vehicle is started and the vehicle air conditioner is triggered to start, the fan speed in the vehicle air-conditioning module and the fan speed in the seat ventilation module are determined by obtaining temperature data and pressure data, and then the operation of the vehicle air-conditioning module is controlled according to the fan speed in the vehicle air-conditioning module, and the operation of the target fan in the seat ventilation module is controlled according to the fan speed in the seat ventilation module. Thus, the automatic opening of the seat ventilation is achieved through the present application, and automatic adjustment and control can be performed based on temperature data without manual adjustment. Therefore, the intelligence and effectiveness of the car seat ventilation can be improved through the present application.

[0021] Specific as Figure 2 As shown, this embodiment provides a vehicle seat ventilation method with multiple control modes, and the method is applied to a seat ventilation controller in a vehicle seat ventilation system with the above-mentioned multiple control modes. The execution steps of the method are: 201, when the vehicle is started and the vehicle air conditioner is triggered to start, the temperature inside the vehicle and the temperature outside the vehicle are obtained through the temperature sensor, and the pressure data of the seat and the seat back are obtained through the pressure sensor.

[0022] Specifically, in this embodiment, the temperature outside the vehicle can be obtained by a temperature sensor disposed outside the vehicle, the temperature inside the vehicle can be obtained by a temperature sensor disposed inside the vehicle, the pressure data of the seat can be obtained by a pressure sensor disposed at the bottom of the seat, and the pressure data of the seat back can be obtained by a pressure sensor disposed on the seat back.

[0023] 202 , determining a location area where the user contacts the seat and the seat back based on pressure data of the seat and the seat back.

[0024] In an optional embodiment provided in the present application, the determining of the position area where the user contacts the seat and the seat back through pressure data of the seat and the seat back includes: determining the position points where the user contacts the seat and the seat back through pressure data of the seat and the seat back, matching the position coordinate points with models of the seat and the seat back to determine matching position coordinate points, performing cluster calculations on the matching position coordinate points, and determining the position area where the user contacts the seat and the seat back based on the results.

[0025] The seat and seat back model is a simulation structure diagram of the seat and seat back, and the position coordinate points are loaded into the simulation structure diagram, that is, the matching position coordinate points in the simulation structure diagram are determined, and then the matching position coordinate points are clustered to obtain the position area where the user contacts the seat and the seat back. For example, the user is in the main driver's seat, and his sitting posture is that his buttocks contact the seat and his back contact the lower half of the seat back, that is, the contact area is the seat and the lower half of the seat back.

[0026] 203 , obtaining other position areas in the seat and the seat back except the position area.

[0027] Specifically, this embodiment can determine other position areas other than the position area based on the simulation structure diagram mentioned in the previous step. If the contact area is directly above the seat and the lower half of the seat back, the other position areas can be the upper half of the seat back, directly below the seat, the front side of the seat, the rear side of the seat, the back of the seat back, etc. This embodiment does not specifically limit this.

[0028] 204 , determining a target fan in the seat ventilation module that needs to be activated according to other position areas.

[0029] The seat ventilation module includes multiple fans disposed inside the seat and the seat back, and different fans correspond to different position areas. In this embodiment, the seat and the seat back can be divided into multiple position areas, such as a seat center area, a seat surrounding area, a seat back upper area, and a seat back lower area, and each area corresponds to one or more fans.

[0030] Specifically, the determining the target fan that needs to be activated 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 fan in the matching result as the target fan that needs to be activated in the seat ventilation module. For example, if the other position areas are the area around the seat and the upper area of ​​the seat, the target fans that need to be activated may be fans built into the upper area of ​​the seat and the area around the seat.

[0031] It should be noted that the working principle of the ventilated seat is to add fans in the seat cushion and backrest. These fans inhale the air and introduce it into the ventilation layer. The airflow then penetrates upward from the surface of the ventilation layer and flows to the surface of the seat cover through the heating pad. Because the seat cover is made of perforated leather, air can flow out from the small holes on the seat surface to achieve the ventilation function, allowing passengers to dissipate sweat from their buttocks and backs in hot weather, bringing comfort. Since the user sitting on the car seat will inevitably affect the air intake of 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 lot of noise, which sometimes causes a waste of resources. Therefore, this embodiment determines the target fan that needs to work in the seat ventilation module according to the user's sitting posture (i.e., pressure data), and then the target fan works to smoothly inhale and introduce the air into the circulation layer, thereby achieving ventilation of the car seat while reducing the noise caused by the operation of multiple fans.

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 air-conditioning module can be stopped; if the outside temperature is lower than the second temperature, the heating mode is turned on.

[0035] 2052. If the current working mode is the heating mode, the fan speed in the vehicle air conditioning module is calculated according to the lowest value in the preset temperature range, the vehicle interior temperature, and the temperature difference.

[0038] It should be noted that if the current working mode is the heating mode and the temperature difference is a positive number, it means that the temperature inside the car is greater than the temperature outside the car. At this time, the internal circulation heating of the vehicle air-conditioning module is controlled according to the fan speed in the vehicle air-conditioning module, and heating can be achieved quickly; if the current working mode is the heating mode and the temperature difference is a negative number, it means that the temperature inside the car is lower than the temperature outside the car. At this time, the external circulation heating of the vehicle air-conditioning module is controlled according to the fan speed in the vehicle air-conditioning module, and heating can be achieved quickly.

[0039] 2053. If the current working mode is the cooling mode, the fan speed in the vehicle air-conditioning module is calculated according to the highest value in the preset temperature range, the vehicle interior temperature, and the temperature difference.

[0043] Among them, the calculation of the initial fan speed of the fan in the seat ventilation module based on the in-vehicle temperature, the temperature difference and the preset temperature range includes: calculating the maximum temperature difference between the in-vehicle 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 needs, then calculating the initial fan speed of the fan in the seat ventilation module based on the in-vehicle 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 fan in the seat ventilation module based on the in-vehicle temperature and the temperature difference.
