[0031] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures and technologies are presented to thoroughly understand the embodiments of the present application. However, those skilled in the art should understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0032] A vehicle air system control method and device according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0033] Figure 1 It is a schematic diagram of an application scenario of an embodiment of the present application. The application scenario may include vehicles 1 and 2, a server 3, and a network 4.

[0034] Vehicles 1 and 2 may be hardware or software. When vehicles 1 and 2 are hardware, they may be various in-vehicle electronic devices that support communication with the server 3, including but not limited to in-vehicle communication devices (Telematics-BOX, TBOX), on-board units (OBU), in-vehicle entertainment systems, etc.; when vehicles 1 and 2 are software, they may be installed in the electronic devices described above. Vehicles 1 and 2 may be implemented as multiple software or software modules, or may be implemented as a single software or software module, and the embodiments of the present application do not limit this. Further, various applications may be installed on vehicles 1 and 2, such as data processing applications, instant messaging tools, social platform software, search applications, shopping applications, etc.

[0035] The server 3 may be a server that provides various services. For example, it may be a background server that receives requests sent by terminal devices with which it establishes a communication connection. The background server may receive and analyze requests sent by terminal devices and generate processing results. The server 3 may be a single server, or may be a server cluster composed of several servers, or may also be a cloud computing service center, and the embodiments of the present application do not limit this.

[0036] It should be noted that the server 3 may be hardware or software. When the server 3 is hardware, it may be various electronic devices that provide various services for vehicles 1 and 2. When the server 3 is software, it may be multiple software or software modules that provide various services for vehicles 1 and 2, or may be a single software or software module that provides various services for vehicles 1 and 2, and the embodiments of the present application do not limit this.

[0037] The network 4 may be a wired network connected by coaxial cables, twisted pairs, and optical fibers, or may be a wireless network that can interconnect various communication devices without wiring, such as Bluetooth, Near Field Communication (NFC), Infrared, etc., and the embodiments of the present application do not limit this.

[0038] Vehicles 1 and 2 establish a communication connection with the server 3 via the network 4 to receive or send information, etc. Specifically, at the same time, Vehicle 1 and Vehicle 2 can directly establish a communication connection or establish a communication connection through the network to receive or send information, etc.

[0039] It should be noted that the specific types, quantities, and combinations of Vehicles 1 and 2, the server 3, and the network 4 can be adjusted according to the actual requirements of the application scenario, and the embodiments of the present application do not limit this.

[0040] As mentioned above, to improve the control accuracy of the vehicle-mounted air system, some vehicles are equipped with high-precision air pollutant sensors. When the vehicle detects that the air pollutants around the vehicle exceed the standard, it can adjust the vehicle-mounted air system in a timely manner to protect the health of users. However, the cost of air pollutant sensors is relatively high. For example, the cost of a vehicle-mounted PM2.5 sensor is usually between 400 and 500 yuan. Therefore, not all vehicles will install this sensor.

[0041] In view of this, considering the rapid development of the Internet of Vehicles, most vehicles are equipped with network communication modules, and the single-vehicle data can also be transmitted to the cloud server for analysis and processing. Therefore, the air pollutant detection data uploaded by the vehicles equipped with air pollution source sensors can be obtained through the cloud server and shared with the vehicles in the same area that are not equipped with air pollutant sensors, so that these vehicles can also adjust the vehicle-mounted air system in a timely manner when the air pollutants around the vehicle exceed the standard to protect the health of users.

[0042] It should be noted that in the embodiments of the present application, all operations of vehicles uploading information and data to the server are performed after user authorization.

[0043] Figure 2 It is a flowchart showing the control method of a vehicle-mounted air system provided by the embodiments of the present application. As Figure 2 shown, the control method of the vehicle-mounted air system includes:

[0044] In step S201, in response to the start of the first vehicle, a first signal sent by the first vehicle is received.

[0045] Among them, the first signal at least includes the air system status information of the first vehicle, the first position of the first vehicle, and the first timestamp, and the first vehicle includes at least one vehicle.

[0046] In step S202, a second signal sent by the second vehicle is received.

[0047] Among them, the second signal at least includes the second position of the second vehicle, the air pollutant information detected by the second vehicle, and the second timestamp, and the second vehicle includes at least one vehicle.

[0048] In step S203, in response to determining that the air system of the first vehicle is in a non-purification mode based on the air system status information, a first reference signal is determined from the second signal according to the first position, the first timestamp, the second position, and the second timestamp.

[0049] In step S204, a reference air pollutant concentration is determined based on the air pollutant information in the first reference signal.

[0050] In step S205, in response to the reference air pollutant concentration being greater than the first preset threshold, control information is sent to the first vehicle so that the first vehicle adjusts the air system to the purification mode in response to the control information.

[0051] In the embodiment of the present application, the in-vehicle air system control method can be executed by Figure 1 server 3, where the server can be a cloud server. The cloud server can directly receive the information sent by the vehicle TBOX and send the information to the vehicle TBOX. Alternatively, data can also be forwarded between the cloud server and the vehicle TBOX through an automotive telematics service provider (TSP), that is, the vehicle TBOX first sends the information to the TSP, and the TSP forwards the information to the cloud server. At the same time, the cloud server can also first send the information to the TSP, and then the TSP forwards the information to the vehicle TBOX. When the TSP forwards information for the cloud server and the vehicle TBOX, each piece of information can carry the vehicle identification of the vehicle, such as the vehicle identification number (VIN).

[0052] In the embodiment of the present application, the server can receive a first signal sent by the first vehicle after the first vehicle starts. The first signal at least includes the air system status information of the first vehicle, the first position of the first vehicle, and the first timestamp. It should be noted that the first vehicle can be one vehicle or multiple different vehicles. When the first vehicle is multiple different vehicles, the server receives the first signal of each first vehicle respectively and saves and manages the first signal of each first vehicle respectively. For example, a project can be established for each first vehicle to save and manage the first signal of the first vehicle. Further, the in-vehicle air system of each first vehicle is managed based on each first signal.

[0053] Further, the first vehicle can be a vehicle without an air pollutant detection device installed.

[0054] In the embodiments of the present application, the server may receive a second signal sent by a second vehicle. The second signal includes at least the second position of the second vehicle, air pollutant information detected by the second vehicle, and a second timestamp. It should be noted that the second vehicle may also include one vehicle or multiple vehicles. The server uniformly stores and manages the second signals sent by the received second vehicles. For example, a project may be established for the second signals to store all the second signals sent by the second vehicles.

[0055] Furthermore, the second vehicle may be a vehicle equipped with an air pollutant detection device.

[0056] In the embodiments of the present application, receiving the first signal sent by the first vehicle may be performed after the first vehicle starts, and receiving the second signal of the second vehicle may be a normal operation. That is to say, after the first vehicle starts, it may report the first signal to the server so that the server can determine whether to adjust the air system of the first vehicle according to the received first signal. On the other hand, the server may continuously receive the second signals reported by the second vehicles and store the second signals.

[0057] In the embodiments of the present application, after receiving the first signal, the server may determine the state of the air system of the first vehicle based on the air system state information in the first signal. In response to determining that the air system of the first vehicle is in a non-purification mode according to the air system state information, the server may determine a first reference signal from the second signal according to the first position, the first timestamp, the second position, and the second timestamp. That is to say, when it is determined that the air system of the first vehicle is in a non-purification mode, the server may screen out the first reference signal that meets the position requirements and time requirements from the second signal to use the first reference signal to determine the air quality at the first position where the first vehicle is located.

[0058] In the embodiments of the present application, the reference air pollutant concentration may be determined based on the air pollutant information in the first reference signal. In response to the reference air pollutant concentration being greater than a first preset threshold, control information is sent to the first vehicle so that the first vehicle adjusts the air system to the purification mode in response to the control information. That is to say, after the server screens out the first reference signal, it may obtain the air pollutant information in the first reference signal and determine the reference air pollutant concentration based on the air pollutant information in the first reference signal. Among them, the air pollutant information in the first reference signal with the closest distance between the second position and the first position may be determined as the reference air pollutant concentration. On the other hand, the air pollutant information in all the first reference signals may also be weighted and averaged to determine the reference air pollutant concentration. Among them, the weighting weights may be determined based on the distances between the second positions and the first position in each first reference signal.

[0059] In the embodiments of the present application, when the determined reference air pollutant concentration is greater than the first preset threshold, the server sends control information to the first vehicle. Among them, the control information may be a control instruction, and the control instruction can directly control the first vehicle to adjust the air system to the purification mode. On the other hand, the control information may also be a control reminder message, and the control reminder message can remind the user to perform the operation of adjusting the air system to the purification mode.

[0060] It can be understood that the value of the first preset threshold can be set according to actual needs and is not limited here. In one example, the first preset threshold may be 75 milligrams per cubic meter.

[0061] According to the technical solution provided by the embodiments of the present application, by receiving the first signal of the first vehicle and the second signal of the second vehicle, when it is determined based on the air system status information in the first signal that the air system of the first vehicle is in the non-purification mode, the first reference signal is filtered out from the second signal according to the first position and the first timestamp in the first signal, and the second position and the second timestamp in the second signal, and the reference air pollutant concentration is determined according to the air pollutant information in the first reference signal to judge the air quality of the area where the first vehicle is located. Furthermore, based on the air quality, the on-vehicle air system of the first vehicle is controlled, which can realize the timely and accurate adjustment of the on-vehicle air system of the vehicle without an air pollutant detection device, ensuring user health and improving user experience.

[0062] In the embodiments of the present application, the air system of the first vehicle being in the non-purification mode may be that the air system of the first vehicle operates in the outside air circulation mode, and / or the air purification function of the air system of the first vehicle is not turned on. The air system of the first vehicle being in the purification mode may be that the air system of the first vehicle operates in the recirculation mode, and / or the air purification function of the air system of the first vehicle is turned on.

[0063] Figure 3 It is a schematic flowchart of a method for determining a first reference signal from a second signal provided by an embodiment of the present application. As Figure 3 shown, the method includes the following steps:

[0064] In step S301, the reference distance between the first vehicle and the second vehicle is determined according to the first position and the second position.

[0065] In step S302, the reference time difference is determined according to the first timestamp and the second timestamp.

[0066] In step S303, the second signal with the reference distance less than the preset distance threshold and the reference time difference less than the preset time threshold is determined as the first reference signal.

[0067] In the embodiments of the present application, in order to screen out the first reference signal that meets the position requirements and time requirements from the second signal, the reference distance between the first vehicle and the second vehicle may be determined according to the first position and the second position, and the reference time difference may be determined according to the first timestamp and the second timestamp. Among them, the first position may be represented by the first longitude and latitude, the second position may be represented by the second longitude and latitude, and the reference distance between the first vehicle and the second vehicle may be determined based on the difference between the first longitude and latitude and the second longitude and latitude. On the other hand, the absolute value of the time difference between the first timestamp and the second timestamp may be used as the reference time difference.

[0068] In the embodiments of the present application, the server may determine that the second signal with a reference distance less than the preset distance threshold and a reference time difference less than the preset time threshold is the first reference signal. That is to say, the server may screen out the second signal whose distance from the first vehicle is less than the preset distance threshold and the upload time is within the preset time threshold range of the first vehicle uploading the first signal as the first reference signal, and then determine the air quality at the position of the first vehicle according to the air pollutant information in these second signals uploaded in the same area and within a similar time range.

[0069] According to the technical solution provided by the embodiments of the present application, by obtaining the second signal uploaded by the second vehicle with an air pollutant detection device in the same area and within a similar time range to determine the air quality at the position of the first vehicle, the air quality at the position of the first vehicle can be accurately determined, and then the in-vehicle air system of the first vehicle can be controlled in a timely manner to improve the user experience.

[0070] Figure 4 It is a schematic flowchart of a method for controlling an in-vehicle air system provided by an embodiment of the present application. Among them, Figure 4 Steps S401 to S405 in the illustrated embodiment are basically the same as Figure 2 Steps S201 to S205 in the illustrated embodiment, and will not be elaborated here. As Figure 4 shown, the method further includes the following steps:

[0071] In step S406, in response to the reference air pollutant concentration being less than or equal to the first preset threshold, the first signal is periodically received, and the first reference signal is updated according to each received first signal.

[0072] In step S407, the reference air pollutant concentration is determined based on the air pollutant information in the updated first reference signal until the reference air pollutant concentration is greater than the first preset threshold, or the first vehicle's current driving ends.

[0073] In the embodiments of the present application, when the reference air pollutant concentration determined by the server based on the air pollutant information in the first reference signal is less than or equal to the first preset threshold, it indicates that the air quality around the current first vehicle is good, and there is no need to adjust the vehicle-mounted air system to the purification mode. At this time, since the first vehicle is in a driving state after starting, its position usually changes in real time. Therefore, the server can periodically receive the first signal and update the first reference signal according to the first signal received each time.

[0074] As described above, the server can create an item for each first vehicle, such as creating a form, to save and manage the first signal of the first vehicle. When the first vehicle starts, the server receives and saves the first signal received for the first time in the form; when the vehicle-mounted air system of the first vehicle is not adjusted, the server continues to periodically receive the first signal uploaded by the first vehicle and saves each received first signal in chronological order in the form.

[0075] After receiving a new first signal each time, the server updates the first reference signal with the latest received first signal. That is, the server uses the first position and the first timestamp in the latest received first signal, and the second position and the second timestamp in the second signal to determine the new first reference signal, and then determines the reference air pollutant concentration according to the air pollutant information in the new first reference signal. This is repeatedly executed until the reference air pollutant concentration determined based on the air pollutant information in the updated first reference signal is greater than the first preset threshold, or the current driving of the first vehicle ends. Herein, the end of the current driving of the first vehicle may be that the first vehicle shuts down or the first vehicle loses power.

[0076] In the embodiments of the present application, when the air system status information of the first vehicle should indicate that the air system of the first vehicle is in the purification mode during the server's periodic reception of the first signal reported by the first vehicle, the server may no longer screen the first reference signal in real time based on the second signal to determine the reference air pollutant concentration. The first vehicle can always keep the air system in the purification mode until the user manually adjusts the air system, or the first vehicle receives an air quality prompt message sent by the server, other vehicles or the user terminal, confirms that the current air quality in the area where the first vehicle is located meets the standard, and the first vehicle automatically adjusts the air system to the non-purification mode based on the prompt message.

[0077] According to the technical solution provided by the embodiments of the present application, by periodically receiving the first signal sent by the first vehicle when it is confirmed that the reference air pollutant concentration is less than or equal to the first preset threshold, updating the first reference signal and determining the reference air pollutant concentration, the real-time monitoring of the air of vehicles without installed air pollutant detection devices is realized, and the user experience is improved.

[0078] In the embodiments of the present application, a first time period can be used to periodically receive a first signal.

[0079] Figure 5 It is a schematic flowchart of a method for determining a first time period provided by the embodiments of the present application.

[0080] Such as Figure 5 shown, the method includes the following steps:

[0081] In step S501, a judgment area is determined according to the first position.

[0082] In step S502, wind speed information and rainfall information of the judgment area are obtained.

[0083] In step S503, a first time period is determined based on the wind speed information and the rainfall information.

[0084] In the embodiments of the present application, the first time period can be adjusted based on the climate conditions in the area where the first vehicle is located. Specifically, the server can first determine a judgment area according to the first position. In one example, the server can determine an area within a preset radius centered on the first position as the judgment area. It can be understood that in practical applications, other methods can also be used to determine the judgment area, which is not limited here.

[0085] In the embodiments of the present application, the server can obtain the wind speed information and rainfall information of the judgment area. In one example, the server can synchronously obtain the wind speed information and rainfall information of the judgment area from a third-party weather platform. Further, to ensure the rationality of the time deviation, the obtained wind speed information and rainfall information can be the information of the judgment area within a preset time range, such as the wind speed information and rainfall information of the judgment area in the most recent 1 hour. Furthermore, the server can determine a first time period based on the obtained wind speed information and rainfall information.

[0086] It can be understood that the greater the wind speed and the greater the rainfall, the lower the pollutant concentration in the air. Therefore, when determining the first time period based on the obtained wind speed information and rainfall information, the wind speed information and rainfall information can be referred to. When the wind speed is relatively high and / or the rainfall is relatively large, the first time period is determined as a relatively long calculation period. On the contrary, when the wind speed is relatively low and / or the rainfall is relatively small, the first time period is determined as a relatively short calculation period.

[0087] Table 1 shows an example of determining the first signal reception frequency based on wind speed and rainfall. The first time period can be calculated according to this first signal reception frequency. Where m represents meter, mm represents millimeter, s represents second, and min represents minute.

[0088] Table 1

[0089]

[0090] According to the technical solution provided by the embodiment of the present application, by adjusting the first time period based on the climate conditions in the area where the first vehicle is located, the air quality judgment efficiency can be improved and resource waste can be reduced.

[0091] In the embodiment of the present application, the service area can also record the calculated air pollutant concentrations at each location. When it is determined that the air pollutant concentrations at multiple adjacent locations in the same area are all greater than the first preset threshold at similar times, the area is marked as a polluted area.

[0092] Figure 6 It is a schematic flowchart of a vehicle-mounted air system control method provided by an embodiment of the present application. Among them, Figure 6 Steps S601 to S605 in the illustrated embodiment are basically the same as Figure 2 Steps S201 to S205 in the illustrated embodiment, and will not be elaborated here. As Figure 6 shown, the method further includes the following steps:

[0093] In step S606, in response to sending control information to the first vehicle, mark the first location as a polluted location.

[0094] In step S607, with a specific polluted location in the polluted locations as the center, cluster all the polluted locations within a preset range.

[0095] In step S608, in response to the number of polluted locations obtained by clustering being greater than the second preset threshold, determine the preset range as a polluted area.

[0096] In step S609, in response to determining that the third vehicle enters the polluted area and the air system status information of the third vehicle is in a non-purification mode, send control information to the third vehicle so that the third vehicle adjusts the air system to the purification mode in response to the control information.

[0097] Among them, the third vehicle is at least one vehicle among the first vehicles.

[0098] In the embodiment of the present application, after the server sends control information to the first vehicle, it can mark the first location as a polluted location. As mentioned above, the first vehicle can also be multiple vehicles. That is to say, the server can receive the first signals sent by multiple first vehicles respectively, and determine whether to send control information to each first vehicle in combination with the second signal received by the server. After the server sends control information to the first vehicle, it can mark all the first locations in the first signals sent by each first vehicle as polluted locations. Subsequently, the server can cluster all the polluted locations within a preset range with a certain specific polluted location in the polluted locations as the center. If the number of polluted locations obtained by clustering is greater than the second preset threshold, it can be considered that there is a pollution source in this area, and the server can determine the preset range as a polluted area. The value of the second preset threshold can be set according to actual needs and is not limited here.

[0099] Among them, the clustering algorithm can use the Density-Based Spatial Clustering of Applications with Noise (DBSCAN). For example, let the initial value of the minimum number of polluted location points (MinPts) be 5, and scan with a specific polluted location as the center and a radius of 1 kilometer. When there are 5 or more polluted locations within 1 kilometer of the scan, use the other polluted locations obtained by the scan as new centers and continue to scan with a radius of 1 kilometer until the number of polluted locations in the areas scanned with all the polluted locations obtained by the scan as the centers and a radius of 1 kilometer is less than 5. At this time, the area obtained by the scan can be determined as the polluted area.

[0100] In the embodiment of the present application, after the service area receives the first signal reported by the third vehicle, when it is determined based on the air system state information in the first signal that the air system of the third vehicle is in a non-purification mode and based on the first location in the first signal that the third vehicle is located in the polluted area, it can directly send control information without calculating the air pollutant concentration at the location of the third vehicle in real time to control or prompt the third vehicle to adjust the air system to the purification mode. The third vehicle is at least one of the first vehicles.

[0101] According to the technical solution provided by the embodiment of the present application, by marking the area as a polluted area when it is determined that the air pollutant concentrations at multiple adjacent locations in the same area are all greater than the first preset threshold at a similar time, and directly controlling or prompting the vehicle to adjust the air system when a vehicle without an air pollutant detection device enters this area, the adjustment speed can be increased and the user experience can be improved.

[0102] On the other hand, some air pollution sources, such as construction sites, may disappear over time. Therefore, when the pollution source disappears, it is also necessary to adjust the polluted area and re-label it as a normal area.

[0103] Figure 7 is a schematic flowchart of a vehicle air system control method provided by an embodiment of the present application. Among them, Figure 7 Steps S701 to S709 in the illustrated embodiment are substantially the same as Figure 6 Steps S601 to S609 in the illustrated embodiment, and will not be described in detail here. As Figure 7 shown, the method further includes the following steps:

[0104] In step S710, a second signal whose second position is located in the polluted area and the time difference between the second timestamp and the current time is less than a preset time threshold is determined as a second reference signal.

[0105] In step S711, using a second time period, periodically determine the reference air pollutant concentration of the polluted area based on the air pollutant information in the second reference signal.

[0106] In step S712, in response to the reference air pollutant concentration of the polluted area being less than a first preset threshold, determine that the polluted area is a normal area.

[0107] Among them, the second time period is greater than the first time period.

[0108] In an embodiment of the present application, a second signal whose second position is located in the polluted area and the time difference between the second timestamp and the current time is less than a preset time threshold can be screened out as a second reference signal, and using a second time period, periodically determine the reference air pollutant concentration of the polluted area based on the air pollutant information in the second reference signal. When the reference air pollutant concentration of the polluted area is less than a first preset threshold, determine that the polluted area is a normal area. Among them, the second time period can be greater than the first time period. That is to say, the judgment of whether the pollution source has disappeared can be carried out at a lower frequency, because usually, the disappearance speed of the pollution source is much slower than the vehicle movement speed.

[0109] According to the technical solution provided by the embodiment of the present application, by periodically detecting the polluted area at a lower frequency, when it is determined that the air pollutant concentration of the polluted area is less than a first preset threshold, the polluted area is corrected to a normal area, thereby avoiding misjudgment of the polluted area, resulting in unnecessary air system adjustment and saving resources.

[0110] All of the above optional technical solutions can be combined arbitrarily to form optional embodiments of the present application, which will not be described in detail here.

[0111] Figure 8 This is a signal interaction diagram of a vehicle air system control method provided by an embodiment of the present application. As Figure 8 shown, the data sharing center in the cloud server can receive signals sent by vehicles without in-vehicle PM2.5 sensors. Among them, vehicles without in-vehicle PM2.5 sensors can periodically send the air-conditioning internal / external circulation status signal 1 and the air purification system switch status signal 2 to the vehicle's TBOX by the air system control module. The TBOX forwards signal 1, signal 2, and the vehicle's longitude and latitude information to the TSP, and then the TSP forwards signal 1, signal 2, and the vehicle's longitude and latitude information to the data sharing center. Among them, when the TSP forwards signal 1, signal 2, and the vehicle's longitude and latitude information, it also needs to carry the vehicle's VIN and timestamp.

[0112] The shared data center can also receive the PM2.5 data of surrounding vehicles, and preprocess and store the received data. The shared data center makes a cyclic judgment and big data calculation based on the received PM2.5 data of surrounding vehicles, signal 1, signal 2, the vehicle's longitude and latitude information, and timestamp. Among them, the premise of the calculation needs to meet that the vehicle air conditioner is in the "external circulation state" judged according to signal 1, and / or the vehicle air purification system is not turned on judged according to signal 2. The calculation rule can be to obtain the PM2.5 value closest to the current VIN position in the PM2.5 sensor stock vehicle data within a range with a coverage radius of 5 kilometers and a time window of 30 minutes based on the longitude and latitude and timestamp of the current VIN. Judge whether the PM2.5 value is greater than 75 milligrams per cubic meter. If so, issue a request instruction to turn on the air-conditioning internal circulation and / or turn on the air purification system. If not, there is no need to issue it.

[0113] When issuing a request instruction to turn on the air-conditioning internal circulation and / or turn on the air purification system, it passes through the data sharing center, TSP, TBOX, and air system control module in sequence. Specifically: the data sharing platform issues an instruction to the TSP only once per single vehicle driving cycle, and carries the vehicle VIN, timestamp, and the request instruction to turn on the air-conditioning internal circulation and / or turn on the air purification system; the TSP calls the request instruction interface to turn on the air-conditioning internal circulation and / or turn on the air purification system from the TBOX; the TBOX issues the opening requirement of the request instruction to turn on the air-conditioning internal circulation and / or turn on the air purification system to the vehicle's air system control module; the vehicle's air system control module returns the execution result, and the vehicle's air system control module only executes the first request instruction to turn on the air-conditioning internal circulation and / or turn on the air purification system within a single driving cycle.

[0114] By adopting the technical solution of the embodiment of the present application, through the PM2.5 data reported by high - end vehicles within a certain time and range of the positions passed by low - end vehicles, after being processed by the big data platform, the effective sharing of sensor data is carried out, providing a basis for judging the in - vehicle air - conditioner turning - on strategy. At the same time, using the density - based clustering algorithm DBSCAN can effectively improve the accuracy of the PM2.5 data set.
