[0002] With the rapid development of vehicle technology, users have increasingly higher requirements for vehicle air quality regulation, especially in scenarios where the smell of bad gases is serious. Since the relevant sensors have a certain delay in collection and execution, it will cause an uncomfortable experience to users, thus affecting the user's driving.

[0003] In related technologies, vehicle air quality systems are mostly based on PM2.5 sensors and AQS (Air Quality Sensor) sensor identification, air dust particle concentration and nitrogen oxide concentration such as automobile exhaust to judge air quality, and then adjust the air conditioning internal and external circulation dampers to prevent bad air from entering the car.

[0004] However, this method cannot accurately identify unpleasant gases that always exist in some areas, such as basements, near garbage disposal stations, and roads with many roadside stalls. Users will still breathe in unpleasant odors for a short period of time, which urgently needs to be solved. Summary of the Invention

[0022] An air quality value at the current vehicle location is determined according to the air dust particle concentration and / or the nitrogen oxide concentration.

[0023] According to the air quality adjustment method of the embodiment of the present application, the air quality value and current air conditioning status of the current vehicle location are obtained. When the air quality value is less than a preset threshold, its duration is obtained. When the duration is greater than or equal to the first preset duration and / or the current air conditioning status is switched to the internal circulation status, the current vehicle location is marked on the vehicle map as the air conditioning air quality adjustment location. When the current vehicle and / or other vehicles enter the air conditioning air quality adjustment location again, the air conditioning status is automatically switched to the internal circulation status.

[0051] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0052] The following describes an air quality control method, device, vehicle, and storage medium according to an embodiment of the present application with reference to the accompanying drawings. To address the problem mentioned in the background art above, whereby sensors are limited by gas concentration and execution time when collecting undesirable gases, and thus cannot accurately identify undesirable gases in multiple scenarios, the present application provides an air quality control method. In this method, the air quality value and current air conditioning state at the current vehicle location are obtained. When the air quality value is less than a preset threshold, its duration is obtained. When the duration is greater than or equal to a first preset duration and / or the current air conditioning state is switched to an internal circulation state, the vehicle's location is marked on an onboard map as an air conditioning air quality control location. When the current vehicle and / or other vehicles enter the air conditioning air quality control location again, the air conditioning state is automatically switched to an internal circulation state. This solves the problem of sensors being limited by gas concentration when collecting undesirable gases, and thus being unable to accurately identify undesirable gases in multiple scenarios. The location of undesirable gases is pre-marked using navigation map positioning data and vehicle information data, allowing the air conditioning to automatically switch to internal circulation, thereby reducing the scenarios and probability of users breathing undesirable gases.

[0053] Specifically, Figure 1 A flow chart of an air quality adjustment method provided in an embodiment of the present application.

[0054] like Figure 1 As shown, the air quality adjustment method includes the following steps:

[0055] In step S101 , the air quality value and current air conditioning status of the current vehicle location are obtained.

[0056] Furthermore, in some embodiments, the air quality value and current air conditioning status of the current vehicle location are obtained, including: obtaining the air dust particle concentration and nitrogen oxide concentration at the current vehicle location identified by the PM2.5 sensor and / or the air quality sensor AQS; and determining the air quality value at the current vehicle location based on the air dust particle concentration and / or nitrogen oxide concentration.

[0057] Specifically, such as Figure 2 and Figure 3As shown, when identifying some adverse gases, the embodiment of the present application first needs to identify the air dust particle concentration and nitrogen oxide concentration at the current vehicle location through the PM2.5 sensor and / or the air quality sensor AQS, and upload them to the vehicle air-conditioning controller through LIN (Local Interconnect Network) communication; secondly, after identifying the air dust particle concentration and nitrogen oxide concentration at the current vehicle location, the air quality value at the current vehicle location is determined according to the obtained air dust particle concentration and / or nitrogen oxide concentration; finally, the adverse gas situation of the current vehicle is further determined based on the obtained air quality value.

[0058] In step S102, if the air quality value is less than the preset threshold, the duration of the air quality value being less than the preset threshold is obtained, and it is determined whether the duration is greater than or equal to the first preset duration, and / or whether the current air-conditioning state is switched to the internal circulation state.

[0059] The preset threshold and the first preset time duration may be thresholds set by those skilled in the art according to actual test conditions, or may be thresholds obtained through multiple computer simulations, and are not specifically limited here.

[0060] Specifically, the air quality value obtained according to the embodiment of the present application is compared with a preset threshold. If the air quality value is less than the preset threshold, it means that the air quality value is not within the normal range, that is, the user can breathe in an odor. At this time, the duration of the air quality value being less than the preset threshold is obtained, and it is determined whether the duration is greater than or equal to the first preset duration, and / or whether the current air-conditioning state is switched to the internal circulation state by the user through the central control screen or a physical switch.

[0061] In step S103, if the duration is greater than or equal to the first preset duration, and / or the current air-conditioning state is switched to the internal circulation state, the current vehicle's position is marked on the on-board map as the air-conditioning air quality adjustment position, and when the current vehicle and / or other vehicles enter the air-conditioning air quality adjustment position again, the air-conditioning state of the current vehicle and / or other vehicles is automatically switched to the internal circulation state.

[0062] For example, when the air quality value at the current vehicle location is less than the preset threshold, assuming that the duration of the air quality value being less than the preset threshold is 4 minutes, and the first preset duration is 3 minutes, it means that the duration is greater than the first preset duration, then the current vehicle location is marked on the on-board map as the air conditioning air quality adjustment position.

[0063] Furthermore, in an embodiment of the present application, if the user turns on the vehicle's central control screen or actively switches the air conditioning state to the internal circulation state, the current vehicle position is marked on the vehicle map as the air conditioning air quality adjustment position.

[0064] Further, in some embodiments, marking the current vehicle position on the on-board map as the air conditioning and air quality adjustment position includes: determining the number of times the current vehicle enters the air conditioning and air quality adjustment position within a second preset time period; if the number of entries is greater than or equal to the first preset number, determining whether the duration is greater than or equal to the first preset time period within the number of entries, and / or the number of adjustments during which the current air conditioning state is switched to the internal circulation state; if the duration is greater than or equal to the first preset time period, and / or if the number of adjustments is greater than the second preset number, marking the current vehicle position on the on-board map as the air conditioning and air quality adjustment position.

[0065] Among them, the second preset time, the first preset number and the second preset number can be thresholds set by technical personnel in this field according to actual test conditions, or can be thresholds obtained through multiple computer simulations, and are not specifically limited here.

[0066] Specifically, such as Figure 2 and Figure 3 As shown, in an embodiment of the present application, after the on-board map marks the current vehicle position as the air conditioning air quality adjustment position (for example, point A1), the map marking points are collected through the CAN (Controller Area Network) bus and sent to the on-board TBOX (Telematics BOX). The on-board TBOX forwards the information to the vehicle backend database through the wireless network for analysis and records the map marking points.

[0067] Furthermore, in an embodiment of the present application, after the on-board TBOX records the map mark point, it is necessary to further determine the number of times the current vehicle enters the air-conditioning air quality adjustment position within the second preset time period. If the number of entries is greater than the first preset number, then determine whether the duration within the number of entries is greater than or equal to the first preset time period, and / or the number of times the current air-conditioning state is switched to the internal circulation state; if the duration is greater than or equal to the first preset time period, and / or, if the number of times the current air-conditioning state is switched to the internal circulation state is greater than the second preset number, then mark the current vehicle position on the on-board map as the air-conditioning air quality adjustment position to obtain a more accurate air-conditioning air quality adjustment position and reduce misjudgment.

[0068] For example, if the second preset time of the embodiment of the present application is 30 days, the first preset number of times is 15 times, the second preset number of times is 15 times, and if the current vehicle enters the air-conditioning air quality adjustment position 17 times within 30 days, then the number of entries at this time is greater than the first preset number. At the same time, it is determined whether the duration is greater than or equal to the first preset time within the number of entries, and / or the number of adjustments for the current air-conditioning state to be switched to the internal circulation state; if the duration is greater than or equal to the first preset time, and / or, if the number of adjustments is 18 times, then the number of adjustments for the current air-conditioning state to be switched to the internal circulation state is greater than the second preset number. At this time, the current vehicle position is marked on the on-board map as the air-conditioning air quality adjustment position.

[0069] It should be noted that the air quality adjustment position of the air conditioner in the embodiment of the present application is based on point A1, and the area within 100 meters of point A1 is recorded as point A1.

[0070] Furthermore, in some embodiments, after the vehicle-mounted map marks the current vehicle's position as the air conditioning air quality adjustment position, the method further includes: updating the vehicle-mounted maps of other vehicles.

[0071] Specifically, in the example of this application, after the on-board map marks the current vehicle position as the air conditioning air quality adjustment position, the software of the Kongming bar controller needs to be upgraded, and the on-board maps of other vehicles need to be updated, so that when subsequent vehicles approach point A1 within a certain range (for example, 300 meters), the air conditioning will be automatically switched to the internal circulation state to reduce the scenario and probability of users breathing in bad gases.

[0072] Furthermore, in some embodiments, after automatically switching the air-conditioning status of the current vehicle and / or other vehicles to the internal circulation state, it also includes: obtaining the target state before switching the air-conditioning status of the current vehicle and / or other vehicles to the internal circulation state; obtaining the distance traveled by the current vehicle and / or other vehicles from the air-conditioning air quality adjustment position; if the distance traveled is greater than the preset release distance, restoring and adjusting the air-conditioning status of the current vehicle and / or other vehicles to the target state.

[0073] The preset release distance may be a threshold value set by those skilled in the art according to actual test conditions, or a threshold value obtained through multiple computer simulations, and is not specifically limited here.

[0074] Specifically, in an embodiment of the present application, if the vehicle's departure distance from point A1 is 1,500 meters, and the preset release position is 1,000 meters, the departure distance is greater than the preset release distance, and the vehicle is released from the internal circulation state. Then, the air-conditioning state of the current vehicle and / or other vehicles is obtained and switched to the target state before the internal circulation state, and the air-conditioning state of the current vehicle and / or other vehicles is restored and adjusted to the target state to ensure the normal operation of the vehicle.

[0075] In summary, the embodiments of the present application have the following advantages:

[0076] (1) Through the comprehensive logical judgment of PM2.5 sensors, AQS sensors, map navigation information, and internal and external circulation opening information, more risk points can be effectively identified, greatly reducing the possibility of users breathing in odors;

[0077] (2) Based on the existing hardware, without any additional cost, the intelligence of air quality control is further improved through the comprehensive judgment of multi-system signals and information.

[0078] According to the air quality adjustment method of the embodiment of the present application, the air quality value and current air conditioning status of the current vehicle location are obtained. When the air quality value is less than a preset threshold, its duration is obtained. When the duration is greater than or equal to the first preset duration and / or the current air conditioning status is switched to the internal circulation status, the current vehicle location is marked on the vehicle map as the air conditioning air quality adjustment location. When the current vehicle and / or other vehicles enter the air conditioning air quality adjustment location again, the air conditioning status is automatically switched to the internal circulation status. This solves the problem that when collecting undesirable gases through sensors, it is limited by gas concentration and cannot accurately identify undesirable gases in multiple scenarios. The location of undesirable gases is marked in advance through navigation map positioning data and vehicle information data, and the air conditioning automatically switches to the internal circulation status, thereby reducing the scenarios and probability of users breathing undesirable gases.

[0079] Next, the air quality control device according to the embodiment of the present application will be described with reference to the accompanying drawings.

[0080] Figure 4 Schematic diagram of an air quality control device according to an embodiment of the present invention.

[0081] like Figure 4 As shown, the air quality adjustment device 10 includes: an acquisition module 100 , a judgment module 200 and a marking module 300 .

[0082] The acquisition module 100 is used to obtain the air quality value and the current air conditioning status of the current vehicle location;

[0083] a determination module 200 for, if the air quality value is less than a preset threshold, obtaining a duration for which the air quality value is less than the preset threshold, and determining whether the duration is greater than or equal to a first preset duration, and / or whether the current air conditioning state is switched to an internal circulation state; and

[0084] The marking module 300 is used to mark the current vehicle's position as an air conditioning air quality adjustment position on the vehicle map if the duration is greater than or equal to a first preset duration and / or the current air conditioning state is switched to the internal circulation state, and automatically switch the air conditioning state of the current vehicle and / or other vehicles to the internal circulation state when the current vehicle and / or other vehicles enter the air conditioning air quality adjustment position again.

[0085] Furthermore, in some embodiments, the marking module 300 includes:

[0086] a determination unit, configured to determine a number of times the current vehicle has entered the air-conditioning air quality adjustment position within a second preset time period;

[0087] If the number of entries is greater than or equal to a first preset number, determining whether a duration within the number of entries is greater than or equal to the first preset duration, and / or the number of times the current air conditioning state is switched to the internal circulation state;

[0088] If the duration is greater than or equal to the first preset duration, and / or if the number of adjustments is greater than the second preset number, the current vehicle position is marked on the vehicle map as the air conditioning air quality adjustment position.

[0089] Furthermore, in some embodiments, after marking the current vehicle location as an air conditioning air quality adjustment location on the vehicle map, the marking module 300 further includes:

[0090] An updating unit is used to update the onboard maps of other vehicles.

[0091] Furthermore, in some embodiments, after automatically switching the air-conditioning state of the current vehicle and / or other vehicles to the internal circulation state, the marking module further includes:

[0092] A first acquiring unit is configured to acquire a target state before switching the air-conditioning state of the current vehicle and / or other vehicles to an internal circulation state;

[0093] A second obtaining unit is used to obtain a distance traveled by the current vehicle and / or other vehicles from the air-conditioning air quality adjustment position;

[0094] If the driving distance is greater than the preset release distance, the air conditioning status of the current vehicle and / or other vehicles is restored and adjusted to the target state.

[0095] Furthermore, in some embodiments, the acquisition module 100 includes:

[0096] a third acquiring unit, configured to acquire the concentration of air dust particles and the concentration of nitrogen oxides at the current location of the vehicle as identified by the PM2.5 sensor and / or the air quality sensor AQS;

[0097] The determination unit is used to determine the air quality value at the current location of the vehicle according to the concentration of dust particles and / or nitrogen oxides in the air.

[0098] According to the air quality control device of the embodiment of the present application, the air quality value and current air conditioning state of the current vehicle location are obtained. When the air quality value is less than a preset threshold, its duration is obtained. When the duration is greater than or equal to the first preset duration and / or the current air conditioning state is switched to the internal circulation state, the current vehicle location is marked on the vehicle map as the air conditioning air quality control position. When the current vehicle and / or other vehicles enter the air conditioning air quality control position again, the air conditioning state is automatically switched to the internal circulation state. This solves the problem that when collecting bad gas through the sensor, it is limited by the gas concentration and cannot accurately identify bad gas in multiple scenarios. The location of the bad gas is marked in advance through navigation map positioning data and vehicle information data, and the air conditioning automatically switches to the internal circulation, thereby reducing the scenarios and probability of the user breathing bad gas.
