Description

Technical Field

[0001] The present invention relates to the technical field of vehicle air conditioning, and in particular to a method and device for controlling a circulation mode of a vehicle air conditioning. Background Art

[0002] The air quality in a vehicle affects the health of the driver and passengers. Most current vehicles are equipped with air conditioners that can adjust their circulation modes. These modes can include internal and external circulation. Internal circulation recycles existing air within the vehicle, allowing it to circulate within the enclosed space without exchanging air with the outside environment. External circulation utilizes air from the outside environment to circulate the air inside the vehicle, maintaining good air flow between the cabin and the outside environment. Currently, vehicle air conditioning circulation mode switching and regulation is primarily manual by the driver or passenger, resulting in a low level of automation and a reduced user experience.

[0060] The following description of exemplary embodiments of the present invention is made in conjunction with the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0061] It should be pointed out that, in the absence of conflict, the embodiments of the present invention and the technical features therein may be combined with each other.

[0062] Figure 1 FIG. 1 is a schematic diagram of the main steps of the vehicle air conditioning circulation mode control method according to an embodiment of the present invention. Figure 1 As shown, the vehicle air conditioning circulation mode control method of the embodiment of the present invention mainly includes the following steps S101 to S103:

[0063] Step S101, monitoring the real-time driving conditions of target vehicles around the vehicle and the real-time environmental information of the vehicle's current environment;

[0064] Target vehicles can be pre-defined vehicles that may emit significant pollution, including but not limited to garbage trucks, trucks, and agricultural vehicles. Agricultural vehicles refer to vehicles that are primarily used for agricultural production and can also be used for transportation or driving, including but not limited to tractors, harvesters, seeders, and three-wheeled agricultural transport vehicles.

[0065] It is understandable that a target vehicle may emit significant pollution under certain driving conditions, thereby affecting nearby pedestrians or occupants, while under other driving conditions, it may emit less pollution, thus having less impact on nearby pedestrians or occupants. Therefore, the real-time driving conditions of the target vehicle can be further determined.

[0066] Real-time environmental information includes road congestion, air conditions, air quality data, and traffic space types. Road congestion can include congested and unobstructed traffic; air conditions can include polluted and clean air; air quality data refers to the air quality of the vehicle's external environment, which can be obtained through the air quality monitoring device pre-installed on the vehicle; and traffic space types can include open and enclosed traffic spaces.

[0067] Among them, open traffic space refers to roads that are not blocked or fenced, and have good air circulation; enclosed traffic space refers to semi-enclosed or closed traffic space, where air circulation is hindered to a certain extent, including but not limited to tunnels, underground garages, etc.

[0068] Among them, the target vehicle, the real-time driving conditions of the target vehicle and the real-time environmental information can be obtained through various software in the vehicle's computer, various sensors pre-installed in the vehicle body or other devices, for example, the target vehicle can be obtained by performing image analysis on image data collected by a camera pre-installed in the vehicle.

[0069] Step S102, analyzing the real-time driving situation and the real-time environmental information;

[0070] By analyzing the real-time driving situation and real-time environmental information, an analysis result is generated, and it is determined whether the air conditioning internal circulation strategy is met based on the analysis result.

[0071] Step S103, when the analysis result indicates that at least one of the above-mentioned real-time driving conditions and the above-mentioned real-time environmental information satisfies the air-conditioning internal circulation strategy, a first control signal indicating the internal circulation mode is generated, and the above-mentioned first control signal is sent to the air-conditioning controller, so that the above-mentioned air-conditioning controller controls the vehicle air-conditioning to the internal circulation mode based on the above-mentioned first control signal.

[0072] When the vehicle air conditioner is in the internal circulation mode and the analysis results indicate that the above-mentioned real-time driving conditions and the above-mentioned real-time environmental information all do not meet the air conditioning internal circulation strategy, a second control signal is generated to indicate to turn off the above-mentioned internal circulation mode, and the above-mentioned second control signal is sent to the air conditioning controller, so that the above-mentioned air conditioning controller turns off the internal circulation mode based on the above-mentioned second control signal, thereby realizing intelligent control of the air conditioning circulation mode.

[0073] By determining the control signal for the circulation mode of the vehicle air conditioner based on the real-time driving conditions of the vehicle and the real-time environmental information of the current environment, the timing for starting the internal circulation can be automatically identified, and the vehicle air conditioner can be automatically controlled to enter the internal circulation mode through the first control signal indicating the internal circulation mode, thereby realizing automatic purification of the air in the vehicle, avoiding the problem of requiring occupants of the vehicle to manually adjust the circulation mode of the vehicle air conditioner according to their own feelings, reducing the driver's manual operations during driving, and improving the user's vehicle experience.

[0074] In an optional embodiment, the above method also includes: when garbage trucks, trucks, and agricultural vehicles are identified to exist within a preset range around the vehicle, directly determining them as target vehicles; in response to identifying the existence of buses and / or public buses within a preset range around the vehicle, obtaining the vehicle type of the buses and / or public buses; determining the buses and / or public buses whose vehicle type indication is a fuel vehicle as target vehicles.

[0075] Target vehicles can be pre-defined vehicle types. Garbage trucks, trucks, agricultural vehicles, and other vehicles typically use diesel as fuel, emitting significant pollutants. In particular, some of these vehicles may not be equipped with or upgraded with emission control devices, resulting in low fuel combustion efficiency and even greater emissions in polluted areas.

[0076] There are two main types of buses and public buses: gasoline-powered vehicles and new energy vehicles powered by hydrogen or electricity. New energy vehicles typically achieve zero or low emissions, with minimal impact on ambient air quality. Therefore, if a bus and / or public bus is identified within a preset range around the vehicle, its type must be further determined. Only buses and / or public buses designated as fuel-powered vehicles will be considered as target vehicles, while buses and / or public buses designated as new energy vehicles will not be considered as target vehicles.

[0077] Furthermore, if a bus and / or public bus is detected within a preset range around the vehicle, its type can be determined by identifying the color of its license plate. The background color of a new energy vehicle's license plate is generally a gradient of white and green or a combination of yellow and green. Therefore, if green is detected in the background color of the license plate, the bus and / or public bus can be determined to be a new energy vehicle.

[0078] It should be noted that with the development of new energy vehicle technology, new energy vehicles that use hydrogen or electricity as their main power source may also appear in vehicles such as garbage trucks and trucks. In this case, after identifying vehicles such as garbage trucks or trucks, their vehicle type can be further determined. If the vehicle type indicates that it is a fuel vehicle, it can be used as the target vehicle.

[0079] In an optional embodiment, the above-mentioned analysis of the real-time driving conditions includes: analyzing whether the driving speed of the target vehicle included in the real-time driving conditions is lower than a first speed threshold; if so, determining whether the real-time driving conditions satisfy the air-conditioning internal circulation strategy; when the driving speed is greater than or equal to the first speed threshold, combining the driving speed and the acceleration included in the real-time driving conditions and / or the driving scene of the target vehicle, judging whether the real-time driving conditions satisfy the air-conditioning internal circulation strategy, and the driving scene indicates whether the target vehicle is in an uphill driving scene.

[0080] The real-time driving condition of the target vehicle may include the driving speed, acceleration and driving scene of the target vehicle.

[0081] It is understandable that when a target vehicle is crawling at a speed below the first speed threshold, it may also be accompanied by frequent acceleration, deceleration, starting, and stopping, which may lead to increased emissions. To avoid the impact on occupants of the vehicle in such situations, when a target vehicle traveling at a speed below the first speed threshold is identified within a preset range around the vehicle, the analysis result can be determined to indicate that the real-time driving conditions meet the air conditioning internal circulation strategy. The first speed threshold is lower than the second speed threshold. For example, the first speed threshold can be 30 km / h and the second speed threshold can be 40 km / h.

[0082] In an optional embodiment, the above-mentioned judgment of whether the above-mentioned real-time driving condition satisfies the air-conditioning internal circulation strategy includes: when the above-mentioned driving speed is lower than the second speed threshold and the above-mentioned acceleration is greater than the acceleration threshold, or, the above-mentioned driving speed is lower than the second speed threshold and the above-mentioned target vehicle is in an uphill driving scenario, determining that the above-mentioned real-time driving condition satisfies the above-mentioned air-conditioning internal circulation strategy.

[0083] Therefore, in the process of combining the target vehicle's driving speed, acceleration and driving scene to determine whether its actual driving conditions meet the air-conditioning internal circulation strategy, when the target vehicle's driving speed is greater than or equal to the first speed threshold and less than the second speed threshold, the target vehicle's driving speed is still relatively low. Once the acceleration is greater than the acceleration threshold, a sudden acceleration occurs, and the engine needs to output greater power instantaneously, resulting in increased emissions; when the target vehicle's driving speed is greater than or equal to the first speed threshold and less than the second speed threshold, even if the target vehicle's driving speed is still relatively low, the engine needs to output greater torque due to the need to overcome gravity and do work during climbing, which will result in increased emissions.

[0084] Furthermore, the navigation data and / or image data can be analyzed to determine whether the driving scene of the target vehicle is an uphill driving scene. For example, some navigation software can provide road slope information within a preset range around the vehicle, including but not limited to navigation data such as a 5% slope for a 300-meter uphill slope.

[0085] Optionally, a slope threshold can be pre-set to remove gentle slopes that have little effect on the target vehicle's power from the uphill driving scene. The slope threshold can be set according to actual conditions. For example, the slope threshold can be set to 3%, such as Figure 2 and Figure 3 As shown, there is a target vehicle X2 in front of the vehicle X1. When the target vehicle X2 is in an uphill driving scenario with a slope α less than the slope threshold of 3%, the driver basically does not need to perform special operations such as stepping on the accelerator for the target vehicle X2, and the emissions of the target vehicle X2 may not increase significantly. When the target vehicle X2 is in an uphill driving scenario with a slope α greater than or equal to the slope threshold of 3%, it is necessary to increase the power, and the emissions of the target vehicle X2 may increase significantly.

[0086] In an optional embodiment, analyzing the above-mentioned real-time environmental information includes: analyzing at least one of the road congestion conditions, air conditions and space types of the above-mentioned traffic space included in the above-mentioned real-time environmental information; when the analysis result indicates road congestion and / or air pollution and / or the above-mentioned space type is indicated as an enclosed traffic space, and the first duration of the above-mentioned vehicle being in the above-mentioned road congestion and / or the above-mentioned air pollution and / or the above-mentioned enclosed traffic space is greater than a preset time threshold, determining that the above-mentioned real-time environmental information meets the air-conditioning internal circulation strategy.

[0087] Optionally, the road congestion condition can be determined by identifying the number of vehicles within a preset range around the vehicle and the driving speed of the vehicle and the vehicles within the preset range, or by using navigation data in navigation software. In the case where the road congestion condition is determined by identifying the number of vehicles within a preset range around the vehicle and the driving speed of the vehicle and the vehicles within the preset range, a vehicle number threshold and a driving speed threshold can be pre-set. If the number of vehicles within the preset range around the vehicle is greater than the number threshold and the driving speed of the vehicle and the vehicles within the preset range is less than or equal to the driving speed threshold, the road congestion condition is determined to be road congestion; if the number of vehicles within the preset range around the vehicle is less than or equal to the number threshold, or the driving speed of the vehicle and the vehicles within the preset range is greater than the driving speed threshold, the road congestion condition is determined to be road clear.

[0088] The air condition can be determined by atmospheric environment data in weather software or by air quality data obtained by an air quality monitoring device pre-installed on the vehicle body. Specifically, an atmospheric environment data threshold or an air quality data threshold can be pre-set, and the air condition is determined based on the comparison result of the atmospheric environment data with the atmospheric environment data threshold or the comparison result of the air quality data with the air quality data threshold. If the atmospheric environment data is greater than the atmospheric environment data threshold or the air quality data is greater than the air quality data threshold, the air condition is determined to be polluted; if the atmospheric environment data is less than or equal to the atmospheric environment data threshold or the air quality data is less than or equal to the air quality data threshold, the air condition is determined to be clean.

[0089] The spatial type of a traffic space can be determined by analyzing image data captured by a camera pre-installed on the vehicle, or by using navigation data in navigation software. Specifically, when determining the spatial type of a traffic space through image data analysis, a pre-trained spatial type recognition model can be used to analyze the image data and determine the spatial type of the traffic space the vehicle is located in. The spatial type recognition model can be trained using a big data model using images of traffic spaces pre-labeled with spatial types. The big data model includes, but is not limited to, convolutional neural networks, support vector machines, and the like.

[0090] It is understandable that even if the analysis results indicate road congestion and / or air pollution and / or the above-mentioned space type is indicated as an enclosed traffic space, if the scene of the vehicle being in road congestion and / or air pollution and / or enclosed traffic space only occurs and ends in a short time, it may not have a major impact on the people in the car. The first duration of the vehicle being in road congestion and / or air pollution and / or enclosed traffic space can be further monitored. When the first duration is greater than the preset time threshold, it is determined that the real-time environmental information meets the air-conditioning internal circulation strategy.

[0091] In an optional embodiment, the above-mentioned real-time environmental information also includes: air quality data of the vehicle's external environment acquired by an air quality monitoring device preset on the vehicle body.

[0092] Analyzing the above-mentioned real-time environmental information includes: calculating the rising rate of the above-mentioned air quality data per unit time; in response to the above-mentioned rising rate being greater than or equal to a preset rising rate threshold, determining that the above-mentioned real-time environmental information meets the air conditioning internal circulation strategy.

[0093] In addition to the above analysis of whether the vehicle is in the above-mentioned road congestion and / or the above-mentioned air pollution and / or the above-mentioned enclosed traffic space scenario, the rate of increase of air quality data per unit time can also be calculated. When the rate of increase is less than the preset rate of increase threshold, the road section passed by the vehicle may not have a situation where air pollution gradually increases; when the rate of increase is greater than or equal to the preset rate of increase threshold, the road section passed by the vehicle may have a situation where air pollution gradually increases. Regardless of whether the vehicle is in an air pollution scenario, it can be determined that the real-time environmental information meets the air conditioning internal circulation strategy to generate a first control signal indicating the internal circulation mode, thereby avoiding the gradual increase of pollutants in the external environment affecting the occupants of the vehicle, preventing external pollutants from entering the vehicle, and reducing the inhalation of harmful gases or odors by the occupants of the vehicle.

[0094] In an optional embodiment, in addition to the above-mentioned real-time driving status and environmental information, the vehicle's state may also be monitored. If the vehicle's air conditioning is on and the internal circulation mode is not engaged, and a signal is generated to activate the windshield wipers to spray windshield washer fluid, the vehicle's state satisfies the air conditioning internal circulation strategy, and a first control signal indicating internal circulation mode is generated. If the vehicle's air conditioning is on but not in internal circulation mode, the smell of windshield washer fluid during spraying may enter the vehicle cabin through the air conditioning ducts, causing an unpleasant odor. Therefore, to prevent the smell of windshield washer fluid from affecting vehicle occupants, the vehicle's state in this situation may be determined to satisfy the air conditioning internal circulation strategy.

[0095] In an optional embodiment, before generating the first control signal indicating the internal circulation mode, the method further includes: identifying the window status and door status of the vehicle; in response to the window status and the door status being both closed, executing the step of generating the first control signal indicating the internal circulation mode.

[0096] Because the internal circulation mode primarily recycles existing air within the vehicle cabin and isolates polluted air from the outside environment from entering the cabin, it is necessary to ensure that the windows and doors are closed before activating the internal circulation mode. When it is recognized that both the windows and doors are in the closed state, the step of generating a first control signal indicating the internal circulation mode is executed; when it is recognized that both the windows and doors are in a non-closed state, a prompt message prompting the occupants to close the windows or doors may be generated, or an audio, visual, or voice prompt may be used to prompt the occupants to close the windows or doors. After it is recognized that both the windows and doors are in the closed state, the step of generating the first control signal indicating the internal circulation mode is executed.

[0097] In an optional embodiment, the above method also includes: monitoring the operating mode of the vehicle air conditioner; in response to at least one of the above window status and the above door status being in the open state and the operating mode of the above vehicle air conditioner indicating the internal circulation mode, generating a prompt message to close the window or door; after the above window or the above door is closed, executing the step of generating a first control signal indicating the internal circulation mode.

[0098] When the vehicle air conditioner is in the internal circulation mode, if it is identified that the window status and / or door status are open, a prompt message can be generated to close the window or door, or the occupants of the vehicle can be prompted to close the window or door through sound and light prompts, voice prompts, etc. After identifying that the window status and door status are both closed, the step of generating a first control signal indicating the internal circulation mode is executed, and the air conditioner controller can control the vehicle air conditioner to continue to operate in the internal circulation mode according to the received first control signal.

[0099] Furthermore, when the vehicle air conditioner is in the internal circulation mode, if it is identified that the window status and / or door status are in the open state, it can be further determined whether the vehicle air conditioner is in the process of opening the window based on the third control signal. If it is in the above process, no prompt information is generated to prompt closing the window or door.

[0100] In an optional embodiment, the above method also includes: monitoring the second duration of the vehicle air conditioner being in the internal circulation mode; in response to the second duration reaching a preset internal circulation duration threshold, generating a second control signal instructing to turn off the above internal circulation mode, and sending the second control signal to the air conditioning controller, so that the air conditioning controller turns off the internal circulation mode based on the second control signal.

[0101] In order to prevent the vehicle air conditioner from being in the internal circulation mode for a long time, which will cause the oxygen content in the vehicle to decrease and the carbon dioxide content to increase, affecting the health of the people in the vehicle, the second duration of the internal circulation mode can be monitored after the internal circulation mode is started. Once the second duration reaches the preset internal circulation duration threshold, a second control signal indicating to turn off the internal circulation mode can be generated.

[0102] While the internal circulation mode is turned off based on the second control signal, the external circulation mode can be turned on or the vehicle air conditioner can be turned off.

[0103] Optionally, if the second duration reaches a preset internal circulation duration threshold, a third control signal instructing window opening may be generated, causing the vehicle body controller to open the window based on the third control signal, thereby enabling air circulation between the vehicle cabin and the external environment. The window opening duration is monitored, and if the window opening duration reaches the preset window opening duration threshold, a fourth control signal instructing window closing is generated. As an example, the preset internal circulation duration threshold may be 12 minutes. When the second duration reaches 12 minutes, the third control signal instructing window opening is generated, causing the vehicle body controller to open the window. If the window opening duration reaches the window opening duration threshold of 2 minutes, the fourth control signal instructing window closing is generated, causing the vehicle body controller to close the window.

[0104] According to an embodiment of the present invention, the vehicle air conditioning circulation mode control method monitors and analyzes the real-time driving conditions of target vehicles surrounding the vehicle and the real-time environmental information of the vehicle's current environment. When the air conditioning internal circulation strategy is met, a first control signal indicating the internal circulation mode is generated. This automatically activates the vehicle air conditioning internal circulation mode and automatically purifies the air inside the vehicle, eliminating the need for manual adjustment by the occupants, thereby improving the user's vehicle experience. In addition, by automatically activating the vehicle air conditioning internal circulation mode when the air quality outside the vehicle is poor, the impact of gradually increasing air pollution outside the vehicle on the occupants can be avoided, external pollutants can be prevented from entering the vehicle, and the inhalation of harmful gases or odors by the occupants can be reduced, thereby ensuring the air quality inside the vehicle and the health and safety of the occupants.

[0106] By automatically triggering the start and stop of the internal circulation mode, the tedious manual adjustment operations of the car occupants are avoided, making the control of the air-conditioning circulation mode intelligent. After the vehicle's intelligent driving is turned on, the user's attention to the external environment and driving scenes can be further reduced, thereby improving the user's driving comfort during intelligent driving and enhancing the intelligent experience.

[0173] The modules involved in the embodiments of the present invention may be implemented in software or in hardware. The modules described may also be provided in a processor. For example, they may be described as: a processor including a monitoring module, an analysis module, and a generation module. For another example, they may also be described as: a processor including: a receiving module and a control module. The names of these modules do not, in some cases, constitute a limitation on the modules themselves. For example, the monitoring module may also be described as a "module for monitoring the real-time driving conditions of target vehicles around the vehicle and the real-time environmental information of the vehicle's current environment."

[0174] As another aspect, the present invention further provides a computer-readable medium, which may be included in the device described in the above embodiment; or may exist independently and not be assembled into the device. The computer-readable medium carries one or more programs, and when the one or more programs are executed by a device, the device includes the following steps: monitoring the real-time driving conditions of target vehicles around the vehicle and real-time environmental information of the vehicle's current environment; analyzing the real-time driving conditions and the real-time environmental information; and, if the analysis result indicates that at least one of the real-time driving conditions and the real-time environmental information satisfies the air conditioning internal circulation strategy, generating a first control signal indicating an internal circulation mode, and sending the first control signal to an air conditioning controller, so that the air conditioning controller controls the vehicle air conditioning to the internal circulation mode based on the first control signal.

[0175] According to the technical solution of the embodiment of the present invention, by monitoring and analyzing the real-time driving conditions of target vehicles around the vehicle and the real-time environmental information of the vehicle's current environment, a first control signal indicating the internal circulation mode is generated when the air conditioning internal circulation strategy is met, thereby automatically starting the vehicle air conditioning internal circulation mode and automatically purifying the air inside the vehicle without the need for manual adjustment by the occupants, thereby improving the user's vehicle experience. In addition, by automatically starting the vehicle air conditioning internal circulation mode when the air quality outside the vehicle is poor, the impact of gradually increasing air pollution outside the vehicle on the occupants can be avoided, external pollutants can be prevented from entering the vehicle, and the inhalation of harmful gases or odors by the occupants can be reduced, thereby ensuring the air quality inside the vehicle and the health and safety of the occupants.

[0176] When the vehicle air conditioner is in the internal circulation mode, if the analysis results indicate that the real-time driving conditions and real-time environmental information do not meet the air conditioning internal circulation strategy or the second duration of the vehicle air conditioner in the internal circulation mode reaches the preset internal circulation duration threshold, a second control signal is generated to indicate turning off the above-mentioned internal circulation mode, thereby realizing the automatic turning off of the vehicle air conditioner internal circulation mode, solving the problem that the vehicle air conditioner of this vehicle is in the internal circulation mode for a long time, resulting in a decrease in oxygen content and an increase in carbon dioxide content in the vehicle cabin, which may affect the health of people in the vehicle.

[0177] By automatically triggering the start and stop of the internal circulation mode, the tedious manual adjustment operations of the car occupants are avoided, making the control of the air-conditioning circulation mode intelligent. After the vehicle's intelligent driving is turned on, the user's attention to the external environment and driving scenes can be further reduced, thereby improving the user's driving comfort during intelligent driving and enhancing the intelligent experience.

[0178] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
