[0052] The embodiment of the present invention provides a method for controlling air circulation inside a vehicle, referring to Figure 2 , Figure 2 FIG. 1 is a flow chart of a first embodiment of a method for controlling vehicle interior air circulation according to the present invention.

[0053] In this embodiment, the vehicle interior air circulation control method includes the following steps:

[0054] Step S10: Obtaining in-vehicle passenger information and in-vehicle oxygen volume, and determining an oxygen consumption rate based on the in-vehicle passenger information.

[0055] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication, and program execution functions, such as an on-board computer, tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, such as a vehicle interior air circulation control device. The following uses an on-board computer as an example to illustrate this embodiment and the following embodiments.

[0056] It can be understood that the passenger information in the vehicle can be information about the number and type of passengers in the vehicle; the passenger information in the vehicle can be input by the user, or it can be information measured by a monitoring device installed inside the vehicle. For example, the monitoring device can be a camera, a sensor, etc., which is not limited in this embodiment; the amount of oxygen in the vehicle can be the oxygen content in the passenger space inside the vehicle; the amount of oxygen in the vehicle can be determined based on the volume of the passenger space inside the vehicle and the oxygen content in the air, and can also be measured by sensors or other detection devices with the same or similar functions, which is not limited in this embodiment.

[0057] It should be understood that the oxygen consumption rate can be the rate at which passengers consume oxygen per unit time, for example, the oxygen consumption rate is expressed in milliliters per minute, liters per minute, etc. The oxygen consumption per minute of each passenger can be set equal to b, and the number of passengers in the vehicle can be determined based on the passenger information in the vehicle. The oxygen consumption rate can be obtained by multiplying the number of passengers in the vehicle by the oxygen consumption per minute.

[0058] In the specific implementation, the on-board computer obtains the number of passengers in the car and the amount of oxygen in the car measured by the sensor, multiplies the number of passengers in the car and the oxygen consumption per minute to obtain the oxygen consumption rate. The oxygen consumption per minute can be set in advance.

[0059] Step S20: determining an air renewal time according to the oxygen consumption rate and the oxygen amount in the vehicle.

[0060] It can be understood that the air renewal time can be the time when the external air is exchanged with the air in the vehicle's internal passenger space; when the oxygen amount in the vehicle's internal passenger space is lower than the set oxygen amount, it will cause passengers to experience symptoms such as dizziness and strength. Therefore, the oxygen amount difference can be determined based on the oxygen amount in the vehicle and the set oxygen amount, and the air renewal time can be determined based on the oxygen amount difference and the oxygen consumption rate.

[0061] In a specific implementation, the on-board computer obtains the set oxygen amount, subtracts the oxygen amount in the car from the set oxygen amount to obtain the oxygen amount difference, and determines the air update time based on the oxygen amount difference and the oxygen consumption rate.

[0062] Step S30: generating an air circulation strategy according to the air update time and the vehicle driving information, and updating the air in the vehicle based on the air circulation strategy.

[0063] It can be understood that the vehicle driving information can be monitoring information during the vehicle driving process, for example, the vehicle driving information includes vehicle position information, vehicle speed information, etc.; the air circulation strategy can be a strategy for controlling the exchange of air in the vehicle's internal passenger space with the external air.

[0064] It should be understood that in order to avoid polluted air from entering the seating area inside the vehicle, generating an air circulation strategy based on the air update time and vehicle driving information can be to determine the geographical information of the vehicle's driving area based on the position information during the vehicle's driving process, determine the air pollution area in the vehicle's driving direction based on the geographical information, determine the time period when the vehicle is in the air pollution area based on the vehicle speed information, judge whether the air update time is within the time period, and generate an air circulation strategy based on the judgment result.

[0065] In a specific implementation, the on-board computer obtains the number of occupants and the amount of oxygen in the vehicle obtained through sensor monitoring, multiplies the number of occupants by the oxygen consumption per minute to obtain the oxygen consumption rate, subtracts the amount of oxygen in the vehicle from the set oxygen amount to obtain the oxygen difference, determines the air update time based on the oxygen difference and the oxygen consumption rate, determines the air pollution area in the direction of vehicle travel based on the vehicle's position information, determines the time period when the vehicle is in the air pollution area based on the vehicle speed information, determines whether the air update time is within the time period, generates an air circulation strategy based on the judgment result, and updates the air in the vehicle based on the air circulation strategy.

[0066] Furthermore, in order to improve the accuracy of the air renewal time, the step S20 includes: determining the consumption time according to the oxygen consumption rate and the oxygen amount in the vehicle; and determining the air renewal time according to the consumption time and the current time.

[0067] In the specific implementation, the on-board computer subtracts the oxygen amount in the car from the set oxygen amount to obtain the oxygen amount difference, divides the oxygen amount difference by the oxygen consumption rate to obtain the consumption time, and adds the consumption time to the current time to obtain the air update time.

[0068] Furthermore, if the air inside the vehicle is updated in an air polluted area, the air inside the vehicle will be polluted. In order to prevent polluted air from entering the vehicle and improve the air quality inside the vehicle, step S30 includes:

[0069] Step S301: determining corresponding current map information according to vehicle driving information, and determining an environmentally sensitive area according to the current map information.

[0070] It can be understood that the current map information can be map information within a preset range based on the vehicle's current position and the vehicle's driving direction. The dotted name within the preset range can be determined based on the current map information; the environmentally sensitive area can be an air pollution area.

[0071] In a specific implementation, the on-board computer determines map information within a preset range in the vehicle's driving direction based on the vehicle's location information, determines the place name within the preset range based on the map information, and determines the air pollution area based on the place name and the preset radius.

[0072] In this embodiment, for example, a semicircular area with a preset radius of 500 meters and a preset range of 1000 meters is used. The current map information is determined based on the vehicle's location information. According to the current map information, the names of the places within the preset range are determined to be Tire Factory A and Rubber Factory B. Then, the circular area with a radius of 500 meters and centered on Tire Factory A and Rubber Factory B is the air pollution area.

[0073] Step S302: determining the vehicle entry time and vehicle exit time corresponding to the environmentally sensitive area according to the vehicle's driving speed.

[0074] It is understandable that the driving speed may be the average speed within a preset historical period; the vehicle entry time may be the time when the vehicle enters the environmentally sensitive area; and the vehicle exit time may be the time when the vehicle leaves the environmentally sensitive area.

[0075] In a specific implementation, the on-board computer obtains the average speed of the vehicle within a preset historical period and the first and second distances to the environmentally sensitive area, determines the vehicle's entry time based on the first distance and the average speed, and determines the vehicle's departure time based on the second distance and the average speed.

[0076] Step S303: generating an air circulation strategy according to the vehicle entry time, the vehicle departure time, and the air renewal time.

[0077] In a specific implementation, the on-board computer generates an air circulation strategy that does not update the air in the vehicle in environmentally sensitive areas based on the vehicle entry time, vehicle departure time and air update time.

[0078] Step S304: updating the air inside the vehicle based on the air circulation strategy.

[0079] This embodiment obtains in-vehicle passenger information and in-vehicle oxygen levels, and determines an oxygen consumption rate based on the in-vehicle passenger information; determines an air refresh time based on the oxygen consumption rate and in-vehicle oxygen levels; generates an air circulation strategy based on the air refresh time and vehicle driving information, and refreshes the in-vehicle air based on the air circulation strategy. Because this embodiment determines the air refresh time based on the oxygen consumption rate determined from in-vehicle passenger information and the in-vehicle oxygen levels, and refreshes the in-vehicle air based on the air refresh time and the air circulation strategy generated from the vehicle driving information, it can improve the in-vehicle oxygen content while reducing energy consumption, thereby enhancing the accuracy of in-vehicle air circulation control.

[0080] refer to Figure 3 , Figure 3 FIG. 2 is a flow chart of a second embodiment of a vehicle interior air circulation control method according to the present invention.

[0081] Based on the above first embodiment, in this embodiment, step S303 includes:

[0082] Step S3031: Determine whether the air update time is before the vehicle entry time.

[0083] In a specific implementation, the driving computer determines whether the air update moment is before the vehicle enters the environmentally sensitive area.

[0084] Step S3032: If not, determine whether the air renewal time is after the vehicle departure time.

[0085] In a specific implementation, if the air update time is not before the vehicle's entry time, the air update time may be within the time period when the vehicle is driving in an environmentally sensitive area. At this time, the on-board computer determines whether the air update time is after the vehicle's departure time when the vehicle leaves the environmentally sensitive area.

[0086] Step S3033: If yes, then when the air renewal time is reached, an air circulation strategy is generated to start the air conditioning external circulation and / or open the windows.

[0087] In a specific implementation, if the air update time is after the vehicle leaves, it means that updating the air in the car at this time will not exchange polluted air into the car, and the on-board computer generates an air circulation strategy to start the air conditioning external circulation and / or open the windows.

[0088] Furthermore, since the wind direction will affect the flow direction of polluted air, in order to avoid exchanging polluted air into the car due to the influence of wind direction when updating the air in the car, after step S3031, it also includes: if yes, obtaining the current distance between the vehicle and the environmentally sensitive area; when the current distance is less than the preset distance, determining the current wind direction according to the current weather information of the vehicle's driving area; judging whether the vehicle's driving direction is consistent with the current wind direction; if yes, generating an air circulation strategy for starting the air conditioning external circulation and / or opening the windows when the air update time is reached.

[0089] In a specific implementation, when the air update moment is before the vehicle enters, the on-board computer obtains the current distance between the vehicle and the edge area of ​​the environmentally sensitive area close to the vehicle. When the current distance is less than the preset distance, the current wind direction is determined based on the current weather information of the driving area. When the current wind direction is consistent with the vehicle's driving direction, it indicates that the wind is blowing the polluted air away from the vehicle. When the air update moment is reached, an air update strategy is generated to start the air conditioning external circulation and / or open the windows.

[0090] This embodiment determines whether the air refresh time is before the vehicle's entry time; if not, it determines whether the air refresh time is after the vehicle's departure time; if so, it generates an air circulation strategy for activating the air conditioning's external circulation and / or opening the windows upon reaching the air refresh time. By determining the relationship between the air refresh time, the vehicle's entry time, and the vehicle's departure time, this embodiment generates an air circulation strategy for activating the air conditioning's external circulation and / or opening the windows. This avoids air contamination inside the vehicle by refreshing the vehicle's interior in environmentally sensitive areas, thereby improving air quality.

[0091] refer to Figure 4 , Figure 4 FIG. 4 is a flow chart of a third embodiment of a vehicle interior air circulation control method according to the present invention.

[0092] Based on the above embodiments, in this embodiment, step S10 includes:

[0093] Step S101: Obtain in-vehicle passenger information and in-vehicle oxygen level, and determine the passenger type based on the in-vehicle passenger information.

[0094] It is understandable that the passenger type may be the age type of the passengers in the vehicle; for example, the passenger types include children, teenagers, young and middle-aged people, and the elderly, etc., which is not limited in this embodiment.

[0095] Step S102: determining the unit oxygen consumption rate corresponding to each passenger in the vehicle according to the passenger type and a preset mapping relationship, and determining the oxygen consumption rate according to the unit oxygen consumption rate.

[0096] It is understandable that people of different age groups consume different amounts of oxygen per minute. The preset mapping relationship can be a correspondence between a preset passenger type and a unit oxygen consumption rate; determining the oxygen consumption rate based on the unit oxygen consumption rate can be to add the unit oxygen consumption rates to obtain the total oxygen consumption rate of the passengers in the vehicle.

[0097] Furthermore, in order to improve the accuracy of the in-vehicle passenger information, before step S10, it also includes: obtaining the in-vehicle environment video captured by the in-vehicle camera, selecting a target video frame from the in-vehicle environment video; selecting an area of ​​interest from the target video frame, and performing face recognition on the area of ​​interest; and determining the in-vehicle passenger information based on the face recognition result.

[0098] In a specific implementation, the on-board computer obtains a video of the interior environment of the vehicle captured by the in-vehicle camera within a preset time period, selects a target video frame according to the clarity of each video frame of the interior environment video, selects a region of interest containing a face from the target video frame, and removes the image area outside the region of interest to obtain a number of regions of interest corresponding to the number of passengers in the vehicle, performs face recognition on the several regions of interest, and determines the passenger type of the passengers in the vehicle based on the recognition results.

[0099] This embodiment obtains in-vehicle passenger information and in-vehicle oxygen levels, determines the passenger type based on the in-vehicle passenger information, determines the unit oxygen consumption rate corresponding to each in-vehicle passenger based on the passenger type and a preset mapping relationship, and determines the oxygen consumption rate based on the unit oxygen consumption rate. This embodiment determines the oxygen consumption rate based on the unit oxygen consumption rate determined from the passenger type and the preset mapping relationship table, thereby improving the accuracy of the in-vehicle passenger oxygen consumption rate.

[0100] In addition, an embodiment of the present invention further provides a storage medium storing a vehicle interior air circulation control program. When the vehicle interior air circulation control program is executed by a processor, the steps of the vehicle interior air circulation control method described above are implemented.

Because this embodiment determines the air refresh time based on the oxygen consumption rate determined from in-vehicle passenger information and the in-vehicle oxygen levels, and refreshes the in-vehicle air based on the air refresh time and the air circulation strategy generated from the vehicle driving information, it can improve the in-vehicle oxygen content while reducing energy consumption, thereby enhancing the accuracy of in-vehicle air circulation control.
