[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] Overview

[0038] In modern automotive design, passenger comfort and energy efficiency are two core considerations. With the advancement of intelligent automotive technology, intelligently adjusting the air conditioning system based on the actual conditions within the passenger cabin to achieve optimal comfort and energy efficiency has become a pressing issue.

[0039] In the existing technology, pressure relief vents fixed on both sides of the vehicle trunk are usually used to regulate the air circulation in the passenger compartment, discharge the dirty gas in the passenger compartment, and when the vehicle is parked outdoors for a long time and the temperature inside the vehicle changes drastically, the air conditioning system is used to introduce relatively cool or warm outside air to achieve cooling or heating effects more quickly.

[0040] However, since the position and number of the pressure relief vents used to regulate the air circulation in the passenger compartment are fixed, when there are fewer passengers in the vehicle, the vehicle's air conditioning system may be overused, resulting in reduced passenger comfort and increased energy consumption of the entire vehicle.

[0041] On this basis, the inventors discovered through further research that by obtaining the in-vehicle status information, namely the number and position of passengers in the vehicle, and based on the number and position of passengers in the vehicle, at least one of the multiple pressure relief ports respectively arranged at different positions of the vehicle is determined to be the first target pressure relief port, and the first target pressure relief port is controlled to be opened, and the second target pressure relief ports other than the first target pressure relief port among the multiple pressure relief ports are controlled to be closed. Compared with the pressure relief port opening scheme using a fixed mode, controlling the first target pressure relief ports at different positions to be opened and controlling the second target pressure relief ports at other positions to be closed based on the number and position of passengers in the vehicle can effectively reduce unnecessary air circulation inside and outside the vehicle, avoid excessive work of the air-conditioning system, ensure user comfort and reduce the energy consumption of the entire vehicle.

[0042] Based on the above concept, an embodiment of this specification provides a pressure relief vent control method, which will be exemplarily described below with reference to the accompanying drawings.

[0043] Exemplary Methods

[0044] See also Figure 1 In an exemplary embodiment, a pressure relief port control method is provided, which is applied to a vehicle controller, the vehicle controller being located in a vehicle, and the vehicle being provided with a plurality of pressure relief ports, the plurality of pressure relief ports being located at different positions of the vehicle. Figure 1 As shown, the pressure relief port control method includes steps S101-S103:

[0045] S101: Obtain vehicle status information.

[0046] The in-vehicle status information includes the number of passengers in the vehicle and the positions of the passengers in the vehicle.

[0047] Specifically, an occupant (number) sensor is arranged in the vehicle, which is used to accurately sense the number and position of occupants in the vehicle.

[0048] The vehicle controller obtains the number and position of passengers in the vehicle in real time through the passenger sensors arranged in the vehicle.

[0049] Among them, the passenger position can be located only in the front seats and the rear seats, or in the main driver's seat, the co-pilot seat and the rear seats, or more accurately in the main driver's seat, the co-pilot seat, the left rear seat, the middle rear seat and the right rear seat.

[0050] Among them, the back row mentioned in this article refers to all rows of seats in the vehicle's passenger compartment except the first row / front row where the main driver's seat and the co-driver's seat are located, including the second row, third row, etc.

[0051] Exemplarily, the acquired positions of the passengers in the vehicle include the main driver's seat, the co-driver's seat, the left rear seat, the middle rear seat and / or the middle rear seat.

[0052] Alternatively, by setting a pressure sensor on each seat, obtaining the pressure value obtained by the pressure sensor in real time, when the pressure value obtained by the pressure sensor in real time is greater than the preset pressure value, it is determined that there is an occupant on the seat where the pressure sensor is located. Based on the values of the pressure sensors on each seat, it can be determined whether there is an occupant on each seat, thereby determining the number of occupants in the vehicle and their positions in the vehicle.

[0053] In this way, the number of passengers in the passenger compartment can be monitored in real time through the above-mentioned passenger sensor or pressure sensor, providing accurate data for the intelligent adjustment of the pressure relief port.

[0054] S102: Determine a first target pressure relief port based on in-vehicle state information.

[0055] The first target pressure relief port is at least one of the plurality of pressure relief ports, and the plurality of pressure relief ports are respectively arranged at different positions of the vehicle.

[0056] Specifically, a plurality of pressure relief ports are provided inside the vehicle, including inside the passenger compartment and inside the trunk.

[0057] Specifically, multiple pressure relief ports are provided inside the passenger compartment and the trunk of the vehicle, which are respectively provided in the vehicle roof area, the front and rear left and right door panel areas, and the rear door area.

[0058] More specifically, there are 10 pressure relief ports on the vehicle, which are respectively located in the ceiling area above the main driver's seat, the left front door panel area, the ceiling area above the co-driver's seat, the right front door panel area, the ceiling area above the left side of the rear row (generally referring to the second row), the left door panel area of the rear row, the ceiling area above the right side of the rear row, the right door panel area of the rear row, and the left and right sides of the tailgate.

[0059] For example, the 10 pressure relief ports are 1#, 2#, 3#, 4#, 5#, 6#, 7#, 8#, 9#, and 10#, and the position distribution of these 10 pressure relief ports can be as follows: Figure 2 As shown in (a) and (b), seats 1# and 2# are located on the ceiling above the driver's seat and inside the left front door panel, respectively; seats 5# and 6# are located on the left side of the second row of seats, above the ceiling and inside the left door panel, respectively; seats 3#, 4#, 7#, and 8# are symmetrically located on the right side of the vehicle; and seats 9# and 10# are located on the left and right sides of the rear door, respectively.

[0060] Specifically, a target number, or the first target number of pressure relief ports, is first determined based on the number of occupants in the vehicle. Then, based on the occupant positions in the vehicle, the target number of pressure relief ports closest to the occupant positions among the multiple pressure relief ports is determined as the first target pressure relief ports. There is a correspondence between the number of occupants in the vehicle and the first target number of pressure relief ports, with different numbers of occupants corresponding to different target numbers. For example, if the number of occupants in the vehicle is 1, the corresponding first target number of pressure relief ports is 2.

[0061] In this way, determining the appropriate number of first target pressure relief vents based on the number of occupants in the vehicle prevents excessive air conditioning system operation caused by opening too many vents, thereby saving energy. The closest pressure relief vent is determined as the first target pressure relief vent based on the position of the occupants in the vehicle, ensuring that airflow from the air conditioning outlet flows through or around the occupants before being discharged outside the vehicle, reducing unnecessary circulation, quickly lowering or raising the occupant's body temperature and surrounding temperature, and improving occupant comfort.

[0062] Alternatively, based on the number and position of passengers in the vehicle, and in conjunction with the air conditioning vents, a pressure relief vent is identified that allows airflow from the vents to flow through all passengers in the vehicle. This serves as the primary target pressure relief vent. This ensures that airflow from the vents flows through or around the passengers before exiting the vehicle, reducing unnecessary circulation, quickly lowering or raising the temperature of the passengers' bodies and surrounding areas, and improving passenger comfort.

[0063] Alternatively, there may be a correspondence between the number of passengers, their positions, and different interior regions. In this case, after obtaining the number of passengers and their positions, the corresponding region is searched for, and the region is determined as the target interior region. The correspondence between the number of passengers, their positions, and the interior regions can be obtained by analyzing historical passenger data.

[0064] The vehicle interior area can be divided based on the location of each pressure relief port. Each vehicle interior area has at least one pressure relief port.

[0065] S103: Control the first target pressure relief port to open, and control the second target pressure relief port to close.

[0066] The second target pressure relief port is another pressure relief port among the multiple pressure relief ports except the first target pressure relief port.

[0067] Specifically, the vehicle controller sends an open command to the first target pressure relief port. Upon receiving the open command, the first target pressure relief port controls the exhaust valve of the first target pressure relief port to open. The vehicle controller sends a close command to the second target pressure relief port. Upon receiving the open command, the second target pressure relief port controls the exhaust valve of the second target pressure relief port to close.

[0068] In this embodiment, by obtaining the in-vehicle status information, i.e., the number and positions of the passengers in the vehicle, at least one of the multiple pressure relief ports respectively arranged at different positions of the vehicle is determined to be the first target pressure relief port based on the number and positions of the passengers in the vehicle, and the first target pressure relief port is controlled to be opened, and the second target pressure relief ports other than the first target pressure relief port among the multiple pressure relief ports are controlled to be closed. Compared with the pressure relief port opening scheme adopting a fixed mode, at least one first target pressure relief port at different positions is controlled to be opened based on the number and positions of the passengers in the vehicle, and the second target pressure relief ports at other positions are controlled to be closed. This can effectively reduce unnecessary air circulation inside and outside the vehicle, quickly improve passenger comfort, avoid excessive work of the air-conditioning system, and reduce the energy consumption of the entire vehicle while ensuring user comfort.

[0069] In order to improve user comfort, in some embodiments, the in-vehicle status information also includes the air-conditioning mode. Based on the in-vehicle status information, when determining the first target pressure relief port, the target air vent is determined based on the air-conditioning mode and the position of the passengers in the vehicle, and the operation of the target air vent is controlled. Afterwards, the first target pressure relief port is determined based on the target air vent, the number of passengers in the vehicle, the position of the passengers in the vehicle and the positions of each pressure relief port.

[0070] The target air outlet is at least one of the air-conditioning air outlets available in the air-conditioning mode.

[0071] Specifically, there is a correspondence between the air-conditioning mode, the position of the passenger in the vehicle and the air-conditioning vents, and the air-conditioning vents corresponding to the air-conditioning mode and the position of the passenger in the vehicle in the correspondence are determined as target vents.

[0072] Specifically, first, based on the air conditioning mode, all the air conditioning vents corresponding to the air conditioning mode are determined as the air vents to be selected. That is, the air vents to be selected are all the air conditioning vents that can work in the air conditioning mode.

[0073] For example, if the air conditioning mode is cooling mode, the selected air vents are all air conditioning vents that can operate in cooling mode, including front and rear face vents and even front and rear foot vents. The front and rear face vents are the main air vents in cooling mode, used to blow air with appropriate speed and temperature to the passenger's face area, while the front and rear foot vents are the auxiliary air vents in cooling mode, used to blow air with appropriate speed and temperature to the passenger's foot area.

[0074] Generally, there are usually four front-row face vents, symmetrically distributed in pairs in the center and on both sides of the dashboard. The rear-row face vents are located on the side of the center console facing the rear row or on the B-pillar. The B-pillar refers to the location between the front and rear doors of the vehicle. In addition, there are usually two front-row foot vents. The driver's side foot vent is aimed at the driver's right foot and is located near the accelerator pedal. The passenger side foot vent is relatively flexible in location design, as long as it can cover the position where the passenger's feet may be placed. The rear foot vents are usually located under the front seat or on the rear floor, aimed at the rear passenger's foot area.

[0075] For example, if the air conditioning mode is heating mode, the selected air vents are all air conditioning vents that can work in heating mode, including front and rear row full air vents and even front and rear row face air vents. Among them, the front and rear row full air vents are the main air vents in heating mode, and the front and rear row face air vents are auxiliary air vents.

[0076] For example, if the air conditioning mode is in defrost mode, the selectable air vents are all defrost vents that can operate in defrost mode. Since defrost mode in air conditioning generally refers to defrosting the front windows, and rear window defrosting is usually achieved through resistance heating and has nothing to do with air conditioning, the air vents that can operate in defrost mode are generally the defrost vents on the front windows.

[0077] Generally, the optional air outlet refers to the main air outlet, but based on different actual needs, it may also include an auxiliary air outlet.

[0078] Afterwards, based on the position of the occupants in the vehicle, the air vents to be selected are screened, and the air vents that pass the screening are determined as target air vents.

[0079] Among them, the screening method can be to retain the air vents that are closest to the passengers in the car among the selected air vents.

[0080] Specifically, when determining the first target pressure relief port, based on the direction of the airflow blown out of the target air outlet and the positions of each pressure relief port, the pressure relief port reached after the airflow passes through the target area in the direction of the airflow is determined to be the first target pressure relief port.

[0081] Among them, in cooling or heating mode, the target area is the area where all passengers in the car are located, which is determined based on the position and number of passengers in the car; in defrost mode, the target area is the area where the front window is located.

[0082] Alternatively, and more specifically, the correspondence between the air vents, the number of passengers in the vehicle, the passenger positions, and the various pressure relief vents is determined. The pressure relief vents corresponding to the air vents, the number of passengers in the vehicle, and the passenger positions are those that meet the passenger compartment's needs. That is, the airflow from the air vents flows through the target area before reaching the pressure relief vent. Passenger compartment needs include defrosting and cooling / heating. Therefore, the pressure relief vent corresponding to the target air vent, the number of passengers in the vehicle, and the passenger positions is determined as the first target pressure relief vent. This effectively meets the needs of the passengers and ensures their comfort.

[0083] In this embodiment, based on the air-conditioning mode and the position of the passengers in the vehicle, the target air vents are determined and the operation of the target air vents is controlled, which can meet the needs of the passengers in the vehicle in the air-conditioning mode in a targeted manner, thereby ensuring the comfort of the passengers in the vehicle. On this basis, since the air flow direction inside the vehicle is from the air-conditioning vents to the pressure relief vents, the first target pressure relief vents are determined based on the target air vents, the number of passengers in the vehicle, the position of the passengers in the vehicle and the position of each pressure relief vent. This can ensure that when the first target pressure relief vent is finally determined, the air flow inside the vehicle is discharged from the air-conditioning vents through all the passengers in the vehicle or the defrost area and then out of the vehicle, thereby ensuring the working effect of the air conditioning and improving the comfort of the passengers in the vehicle.

[0084] In order to improve the comfort of the passengers in the vehicle, in some embodiments, the air-conditioning mode is a cooling mode, a heating mode or a defrost mode. Based on the air-conditioning mode and the position of the passengers in the vehicle, when determining the target air vents, if there are passengers only in the front row of the vehicle and the air-conditioning mode is a cooling mode or a heating mode, the target air vents are determined to be the front row air vents; if there are passengers in both the front and rear rows of the vehicle and the air-conditioning mode is a cooling mode or a heating mode, the target air vents are determined to be the front and rear row air vents; if the air-conditioning mode is a defrost mode, the target air vents are determined to be the defrost air vents.

[0085] Based on the position of the passengers in the vehicle, determine whether there are passengers in the front and rear seats of the vehicle.

[0086] If the passenger positions in the vehicle include the back row, it is determined that there are passengers in the back row; if the passenger positions in the vehicle do not include the back row, it is determined that there are no passengers in the back row; if the passenger positions in the vehicle include the front row, such as the main driver's seat, the co-driver's seat, etc., it is determined that there are passengers in the front row.

[0087] In cooling or heating mode, based on the positions included in the vehicle occupant positions, when it is determined that there are only occupants in the front row of the vehicle, the outflow airflow flowing through the air outlet of the front occupant, that is, the front air outlet, is determined to be the target air outlet.

[0088] In cooling or heating mode, based on the positions included in the vehicle passenger position, it is determined that there are passengers in the front and rear rows of the vehicle, and the outflowing airflow passing through the air outlets for the front and rear row passengers, that is, the front row air outlets, and the outflowing airflow passing through the air outlets for the rear row passengers, that is, the rear row air outlets, are determined as target air outlets.

[0089] In the defrost mode, since the airflow from the defrost air vents flows through the front window and has nothing to do with the occupants, the defrost air vents can directly meet the defrosting needs of the passenger compartment. At this time, the defrost air vents can be directly determined as the target air vents.

[0090] In an embodiment of the present application, based on whether there are passengers in the front and rear rows of the vehicle, the air-conditioning mode is cooling / heating, and the air outlet through which the air flows through the passengers is determined as the target air outlet. When the air-conditioning mode is defrosting, the defrost air outlet is determined as the target air outlet. The air outlet that can achieve cooling / heating or defrosting effect can be accurately determined as the target air outlet, thereby ensuring the comfort of the passengers in the vehicle.

[0091] In order to ensure passenger comfort while reducing vehicle energy consumption, in some embodiments, when determining the first target pressure relief port based on the target air vents, the number of passengers in the vehicle, the positions of the passengers in the vehicle and the positions of each pressure relief port, if the target air vents are front row air vents, the pressure relief port located in the front row area of the passenger compartment will be determined as the first target pressure relief port; if the target air vents are front and rear row air vents and the number of passengers in the rear row of the passenger compartment is not greater than a preset number, the pressure relief port located in the rear row area of the passenger compartment will be determined as the first target pressure relief port; if the target air vents are front and rear row air vents and the number of passengers in the rear row of the passenger compartment is greater than a preset number, the pressure relief port located in the trunk area will be determined as the first target pressure relief port; if the target air vents are defrost air vents, the pressure relief port located in the front row ceiling area of the passenger compartment will be determined as the first target pressure relief port.

[0092] Combined with the previous embodiment, if the target air outlet is the front air outlet, it means that there are passengers only in the front row of the passenger compartment, and there are no passengers in the back row of the passenger compartment. At this time, the air flow blown out of the front air outlet passes through the pressure relief outlet closest to the passengers, that is, the pressure relief outlet in the front row area of the passenger compartment.

[0093] The situation where only the front row of the passenger compartment is occupied, while the rear row is empty, can be further divided based on the number and position of passengers in the vehicle. There are situations where only the driver's seat is occupied, and where both the driver and front passenger seats are occupied. Accordingly, the front row area of the passenger compartment can be further divided into the driver's seat area and the front passenger seat area.

[0094] At this point, the presence of occupants in the driver's seat and the front passenger seat can be further determined based on the number and position of occupants in the vehicle. If only the driver's seat is occupied, the pressure relief port in the front driver's seat area is selected as the primary target pressure relief port. If both the driver's seat and the front passenger seat are occupied, the pressure relief port in the front passenger compartment area is selected as the primary target pressure relief port.

[0095] In conjunction with the previous embodiment, if the target air outlet is the front or rear row air outlet, it means that there are passengers in both the front and rear rows of the passenger compartment. At this time, based on the number of passengers in the vehicle and the positions of the passengers in the vehicle, it is determined whether the number of passengers in the rear row is greater than a preset number. The preset number can be, for example, 1.

[0096] Among them, when the number of rear passengers is not greater than the preset number, since the number of passengers in the car (especially the number of rear passengers) is small, that is, when the air flow blown out from the air outlet passes through the rear passengers, less heat is used, and the temperature of the rear passengers can be lowered / increased more quickly. At this time, directly using the pressure relief port in the rear area as the first target pressure relief port can achieve a better effect of ensuring passenger comfort, avoid unnecessary circulation of hot and cold air, optimize the vehicle air circulation, and thus reduce the energy consumption of the entire vehicle.

[0097] When the number of rear passengers is greater than the preset number, since there are more passengers in the vehicle (especially the number of rear passengers), that is, when the air flow blown out from the air outlet passes through the rear passengers, more heat needs to be consumed to quickly lower / increase the temperature of the rear passengers. At this time, the pressure relief port in the trunk area is used as the first target pressure relief port, so that the gas entering the vehicle through the air outlet can exchange heat with the passengers in the passenger compartment more and be discharged slowly, so that the passengers in the passenger compartment can be fully cooled down / heated up, thereby achieving a better effect of ensuring passenger comfort, avoiding unnecessary circulation of hot and cold air, optimizing the air circulation in the vehicle, and thus reducing the energy consumption of the entire vehicle.

[0098] Combined with the previous embodiment, if the target air outlet is the defrost air outlet, it means that the air-conditioning mode is the defrost mode, and the front defrost mode of the vehicle is the air-conditioning mode for defrosting the front window of the vehicle. At this time, since the air flow blown out by the defrost air outlet flows through the front window of the vehicle for defrosting, after passing the front window of the vehicle, the air flow flows to the roof of the vehicle, and the pressure relief port in the front ceiling area of the passenger compartment close to the defrost air outlet is determined as the first target pressure relief port, which can guide the air flow to be quickly discharged out of the vehicle after flowing through the front window of the vehicle, thereby avoiding the backflow of air flow affecting the defrosting effect and reducing the energy consumption of the entire vehicle.

[0099] In this embodiment, on the basis of the target air outlet, combined with the number of occupants in the vehicle, the positions of the occupants in the vehicle and the positions of each pressure relief outlet, the pressure relief outlet located in the front row of the passenger compartment, the pressure relief outlet in the rear row of the passenger compartment, the pressure relief outlet in the trunk area or the pressure relief outlet in the front ceiling area are determined as the first target pressure relief outlet, so as to achieve the effect of automatically adjusting the position and number of the first target pressure relief outlet according to the number and position of the occupants in the vehicle, thereby realizing personalized occupant comfort adjustment.

[0100] In order to ensure passenger comfort, in some embodiments, when the air-conditioning mode is cooling or heating mode, the exhaust rate of the first target pressure relief port is also controlled based on the temperature of the passengers in the vehicle.

[0101] Among them, the temperature of the occupants in the vehicle is positively correlated with the exhaust rate of the first target pressure relief port.

[0102] That is, as the temperature of the occupant in the vehicle increases, the exhaust rate of the first target pressure relief port increases.

[0103] Specifically, the in-vehicle occupant temperature is determined by temperature sensors provided at each seat, and the in-vehicle occupant temperature refers to the average value of the occupant temperatures detected by the temperature sensors provided at multiple seats.

[0104] Specifically, the exhaust rate of the pressure relief port can be adjusted by adjusting the opening of the exhaust valve of the pressure relief port, and the exhaust rate is positively correlated with the opening of the exhaust valve.

[0105] An exhaust rate of the first target pressure relief port is determined based on the vehicle occupant temperature, and an exhaust valve opening corresponding to the exhaust rate is controlled to control the exhaust valve opening of the first target pressure relief port so that the exhaust rate of the first target pressure relief port reaches a desired exhaust rate.

[0106] Specifically, based on the relationship between the vehicle occupant temperature and the target temperature, the opening of the first target pressure relief port may be controlled to be the target opening to adjust the exhaust rate of the exhaust valve of the first target pressure relief port.

[0107] More specifically, the target temperature includes a first target temperature and a second target temperature. If the occupant temperature in the vehicle is higher than the first target temperature, the opening of the exhaust valve of the pressure relief port is controlled to a first preset opening. If the occupant temperature in the vehicle is lower than the first target temperature and higher than the second target temperature, the opening of the exhaust valve of the pressure relief port is controlled to a second preset opening. If the occupant temperature in the vehicle is lower than the second target temperature, the exhaust valve of the pressure relief port is controlled to close. The first preset opening is greater than the second preset opening, and the first target temperature is higher than the second target temperature.

[0108] It is understandable that when the main driving temperature position is higher than the first target temperature, the intelligent pressure relief port (i.e. the above-mentioned first target pressure relief port) is required to speed up the exhaust valve outlet rate (i.e. the exhaust rate), reduce the circulation time of the outlet airflow in the passenger compartment, increase the new low-temperature airflow to cover the occupants, and speed up the time for the occupants to reach comfort; when the main driving temperature position is lower than the first target temperature and higher than the second target temperature, the intelligent pressure relief port is required to slow down the exhaust valve outlet rate, increase the circulation time of the outlet airflow in the passenger compartment, and continuously maintain the comfort in the passenger compartment; when the main driving temperature position is lower than the second target temperature, the intelligent pressure relief port is required to close the exhaust valve, keep the outlet airflow circulating in the passenger compartment, and avoid overcooling of the occupants in the passenger compartment.

[0109] In this embodiment, the exhaust rate of the first target pressure relief port is controlled based on the temperature of the passengers in the vehicle, so that the opening degree of the pressure relief port can be adjusted intelligently, thereby preventing the air-conditioning system from being unable to intelligently adjust the position and opening degree of the opened pressure relief port (i.e., the exhaust valve opening) when the number of passengers in the passenger compartment changes, thereby affecting the comfort.

[0110] For example, the control logic of the present application may be as follows: Figure 3 As shown, the number and position of passengers in the vehicle are obtained through the passenger number sensor, and different control methods are adopted based on the different number and position of passengers in the vehicle.

[0111] For example, Figure 2 The position distribution of the pressure relief port is shown in the figure. In each air-conditioning mode, only the main air outlet is opened. For example, the preset number corresponding to the number of rear passengers is 1. Figure 3 The logic shown, the method of controlling the pressure relief port in various situations is as follows:

[0112] Case 1: When only the driver is in the car, the air conditioner is turned on, and the air conditioner mode is cooling or heating, control method 1 is activated. Among them, control method 1 is:

[0113] Open only the pressure relief port Figure 2 The pressure relief ports 1# and 2# shown in the figure are all kept closed. In cooling mode, only the front face air vents (the target air vents mentioned above) are opened. In heating mode, only the front full air ducts (or full air vents) are opened. The air conditioning system is controlled to blow air from the front air vents to improve the comfort of the front passengers. After the air is blown out of the air vents, the main air flow flows through the front driver and co-driver seats, wraps around the passengers, and is then discharged through the pressure relief ports. At this time, the flow direction from the air vents to the pressure relief ports in the car can be as follows: Figure 4 shown.

[0114] At the same time, each seat position is equipped with a temperature sensor for monitoring the temperature of the occupants in each seat position. At this time, only the temperature of the occupants in the main driver's seat is monitored. When the main driver's temperature is higher than the first target temperature, the air outlet speed of the exhaust valve of the pressure relief port is accelerated / increased, the circulation time of the airflow from the air outlet in the passenger compartment is reduced, and new low-temperature airflow is added to cover the occupants, speeding up the time it takes for the occupants to reach comfort. When the temperature of the occupants in the main driver's seat is lower than the first target temperature and higher than the second target temperature, the pressure relief port is required to slow down the air outlet speed of the exhaust valve, increase the circulation time of the airflow from the air outlet in the passenger compartment, and continuously maintain the comfort of the passenger compartment. When the temperature of the occupants in the main driver's seat is lower than the second target temperature, the pressure relief port is required to close the exhaust valve, keep the airflow circulating in the passenger compartment, and avoid overcooling of the occupants in the passenger compartment. The larger the opening of the exhaust valve, the higher the air outlet speed.

[0115] Case 2: When there are people in the front driver and co-pilot seats, but no one in the back seat, and the air conditioner is in cooling and heating mode, start control method 2:

[0116] Open as Figure 2 The pressure relief ports 1#, 2#, 3#, and 4# are shown, and the pressure relief ports in other locations remain closed; in cooling mode, only the front face air vents are opened, and in heating mode, only the front foot air ducts are opened, and the air conditioner is controlled to blow air from the front air vents. After the air flow comes out of the front air vents, it covers the left and right passengers in the front row and is then discharged from the pressure relief ports. At this time, the flow direction from the air vents in the car to the pressure relief ports can be as follows Figure 5 As shown by the middle arrow, the temperatures of the two front passengers are monitored simultaneously, and based on the average temperature of the two passengers, the occupant comfort is controlled in the same way as in Case 1 above.

[0117] Case 3: There are people in both the front and rear seats, but only one person in the rear seat (i.e., the number of rear seat passengers is 1), and the air conditioner is in cooling or heating mode, start control method 3:

[0118] Open Figure 2 The pressure relief ports 5#, 6#, 7#, and 8# are shown, and the rest of the pressure relief ports remain closed. In cooling mode, the front and rear face air vents are open, and in heating mode, the front and rear foot air ducts are open. The air flows out of the air conditioning outlet and blows to the front passengers, then flows through the rear passengers, merges with the air flow from the rear air outlet, and is discharged from the rear pressure relief port. At this time, the flow direction from the interior air vent to the pressure relief port can be as follows: Figure 6 As shown by the arrow in the middle, the temperature in the passenger compartment is monitored at the same time, and the passenger comfort is controlled based on the average temperature of each passenger in the passenger compartment in the same manner as in the above case 1.

[0119] Case 4: There are people in both the front and rear seats, and there is more than one person in the rear seat (i.e., the number of rear seat passengers is greater than 1). When the air conditioning mode is cooling or heating, start control method 4:

[0120] Open Figure 2The pressure relief ports 9# and 10# shown in the figure are all kept closed. In cooling mode, the front and rear face air vents are open, and in heating mode, the front and rear foot air ducts are all open. The air flows out of the air conditioning outlet and blows to the front passengers, then flows through the rear passengers, and after merging with the air flow from the rear air outlet, it is discharged from the rear pressure relief port. The air flow fully cools the passenger compartment. At this time, the gas flow from the air outlet to the pressure relief port in the car can be as follows: Figure 7 As shown by the arrow in the middle, the temperature of each occupant in the passenger compartment is monitored at the same time, and the occupant comfort is controlled based on the average temperature of each occupant in the passenger compartment in the same manner as in the above case 1.

[0121] Case 5: There is someone in the car and the front defrost is turned on. Start control method 5:

[0122] Open as Figure 2 The pressure relief ports 1# and 3# shown in the figure guide the airflow from the defrost outlet through the front windshield and out from the roof to avoid the airflow backflow between the instrument panel and the front windshield, which affects the defrosting effect and reduces the energy consumption of the whole vehicle. At this time, the air flow from the interior air outlet to the pressure relief port can be as follows: Figure 8 As shown by the arrow in the middle, the temperature in the passenger compartment is monitored at the same time, and the passenger comfort is controlled based on the average temperature of each passenger in the passenger compartment in the same manner as in the above case 1.

[0130] The functions implemented by the above acquisition module 901, determination module 902 and control module 903 can be implemented in the form of software called by the same or different processors, and the embodiment of the present application is not limited thereto.

[0131] Exemplary Systems

[0132] The present application also provides a pressure relief vent control system, which includes a vehicle controller and multiple pressure relief vents disposed at different locations on the vehicle. The vehicle controller is configured to execute the pressure relief vent control method disclosed in any of the above embodiments.

[0133] Among them, multiple pressure relief ports are located in the front and rear door panel areas, the vehicle roof area and the vehicle back door area. For the introduction of multiple pressure relief ports, please refer to the above description, and their location distribution can be as above. Figure 2 shown.

[0134] Exemplary Pressure Relief Vents

[0135] Another embodiment of the present application further provides a pressure relief port, the structure of which can be as follows: Figure 10 As shown, it includes a controller, a pressure sensor, a compressor, a vacuum pump, an intake valve and an exhaust valve;

[0136] Wherein, the pressure controller is used to monitor the pressure data of the passenger compartment;

[0137] The controller is used to control the operation of the compressor and the vacuum pump based on the passenger compartment pressure data and the atmospheric pressure data under the control of the vehicle controller;

[0138] The compressor is used to pressurize the pressure relief port under the control of the controller when the pressure in the passenger compartment is higher than the atmospheric pressure, so that the pressure in the pressure relief port is lower than the pressure in the passenger compartment and higher than the atmospheric pressure;

[0139] The vacuum pump is used to reduce the pressure of the pressure relief port under the control of the controller when the pressure in the passenger compartment is lower than the atmospheric pressure, so that the pressure of the pressure relief port is lower than the pressure in the passenger compartment;

[0140] The exhaust valve is used to discharge the passenger compartment gas that enters the pressure relief port through the intake valve out of the vehicle.

[0141] Specifically, when the pressure relief vent is working, the pressure sensor collects the passenger compartment pressure data and transmits it to the controller inside it. When the pressure inside the passenger compartment is higher than the atmospheric pressure, the controller needs to control the compressor to start and pressurize the pressure relief vent (or smart pressure relief vent). The pressure range is between the passenger compartment pressure and the atmospheric pressure to ensure that the airflow inside the passenger compartment is discharged out of the vehicle under the action of the pressure gradient.

[0142] When the pressure in the passenger compartment is higher than the atmospheric pressure, the internal controller of the pressure relief port controls the compressor to start and pressurize the pressure relief port so that the pressure of the pressure relief port is between the passenger compartment pressure and the atmospheric pressure to ensure that the airflow in the passenger compartment is discharged out of the vehicle under the action of the pressure gradient.

[0143] When the pressure in the passenger compartment is lower than the atmospheric pressure, the controller inside the pressure relief port first controls the vacuum pump to start, so that the pressure in the pressure relief port is lower than the pressure in the vehicle. Under the action of the pressure gradient, the air flow in the passenger compartment enters the pressure relief port, and the intake valve is closed after it is filled with gas. The controller controls the compressor to start, and after increasing the pressure in the pressure relief port to higher than the atmospheric pressure, the exhaust valve is opened to exhaust outside the vehicle. After the gas is exhausted, the exhaust valve is closed, the vacuum pump is started to decompress the pressure in the pressure relief port, and the intake valve is opened. The cycle is repeated, so that the gas in the passenger compartment is discharged when the pressure in the passenger compartment is lower than the atmospheric pressure.

[0144] Specifically, the vehicle controller sends an open command to the controller of the first target pressure relief port and a close command to the controller of the second target pressure relief port. Accordingly, the controller of the first target pressure relief port, in response to the open command, controls the operation of the compressor and vacuum pump based on the passenger compartment pressure data and atmospheric pressure data. The controller of the second target pressure relief port, in response to the close command, closes the exhaust valve and stops the operation of the compressor and vacuum pump.

[0145] Thus, in this embodiment, the pressure relief port is controlled by the vehicle controller. Regardless of the relationship between the air pressure inside and outside the vehicle, the pressure relief port can be controlled to discharge the air inside the vehicle by controlling the operation of the compressor and the vacuum pump. This does not require being limited by the pressure difference inside and outside the vehicle's passenger compartment, thereby realizing intelligent on-demand exhaust of the pressure relief port.
