Description

Technical Field

[0001] The present application relates to the field of vehicle intelligent control technology, and in particular to a control method, device, vehicle and storage medium for a vehicle air conditioner. Background Art

[0002] In related technologies, intelligent driving control can realize intelligent adjustment of the in-vehicle environment to ensure the comfort of the passengers in the car. For example, environmental data can be collected through in-vehicle / out-of-vehicle temperature sensors, and the cooling / heating power can be adjusted based on the preset temperature threshold. The driver and passengers can be allowed to set different temperature zones (usually two or three zones) through independent control panels, and the air-conditioning system can independently adjust the air supply parameters according to the zone setting values. A time series model can also be established through historical usage data, and the temperature control program can be started in advance when it is predicted that the vehicle is about to enter a high temperature / cold area based on GPS (Global Positioning System) positioning.

[0003] However, in the related technology, it is difficult to achieve differentiated temperature adjustment according to individual differences and actual in-vehicle temperature requirements. Manual adjustment can only achieve relatively rough overall control, such as adjusting the air-conditioning temperature, air-conditioning air volume, air-conditioning blowing mode and air-conditioning blowing direction and other details. It is not easy to adjust them directly at one time, and some adjustment interfaces have deep levels and complex operations. Complex manual adjustment control and fixed threshold adjustment control are also prone to response delays, thereby affecting the comfort of the drivers and passengers in the car, which needs to be improved.

[0036] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0037] The control method, device, vehicle, and storage medium of an in-vehicle air conditioner according to an embodiment of the present application will be described below with reference to the accompanying drawings. In the related art mentioned in the above background art, it is difficult to achieve differentiated temperature adjustment according to individual differences and actual in-vehicle temperature requirements, and the response delays of complex manual adjustment control and fixed threshold adjustment control are relatively large, thus affecting the comfort of in-vehicle passengers. The present application provides a control method for an in-vehicle air conditioner. In this method, when it is detected that the current working condition is an adaptive adjustment working condition, the physiological data of each passenger can be collected, and the internal space of the vehicle can be constructed to determine the actual position of each body part of each passenger according to the internal space. Then, the target requirements of each passenger can be calculated by combining the physiological data and the actual position of the passenger, and the refrigeration operation or heating operation of the in-vehicle air conditioner can be determined to complete the automatic adjustment of the in-vehicle air conditioner. By reusing the existing equipment inside the vehicle, the demand calculation and temperature control for the individual differences of each passenger can be realized, and the comfort of in-vehicle passengers can be guaranteed. Thus, the technical problems in the related art, such as the difficulty in achieving differentiated temperature adjustment according to individual differences and actual in-vehicle temperature requirements, and the relatively large response delays of complex manual adjustment control and fixed threshold adjustment control, which affect the comfort of in-vehicle passengers, are solved.

[0038] Specifically, Figure 1 is a schematic flowchart of a control method for an in-vehicle air conditioner provided by an embodiment of the present application.

[0039] As Figure 1 shown, the control method of the in-vehicle air conditioner includes the following steps:

[0040] In step S101, the current working condition of the in-vehicle air conditioner is detected.

[0041] In the actual execution process, the embodiment of the present application can detect the current working condition of the in-vehicle air conditioner of the vehicle to determine whether the in-vehicle air conditioner is in a manual control working condition, an adaptive adjustment working condition, a closed working condition, etc.

[0042] For example, when performing intelligent control of the in-vehicle air conditioner, the passengers who can perform control operations can open the corresponding intelligent control interface, such as the in-vehicle central control, a mobile terminal associated with the vehicle, or a rear row control terminal, etc., and click the mode activation button to control the in-vehicle air conditioner to enter the corresponding working condition, so that the vehicle can detect the current working condition of the in-vehicle air conditioner according to the above control instruction. Among them, before selecting the mode, the embodiment of the present application can make corresponding selections according to the historical mode selections of the account associated with the intelligent control, and when setting for the first time, the embodiment of the present application can record the first setting result, such as determining the adjustment range, response speed, adjustment period, etc. for the adaptive adjustment working condition, so that it can be directly called later.

[0043] In step S102, when it is detected that the current working condition is the adaptive adjustment working condition, at least one physiological data of each driver and passenger is collected, and the internal space of the vehicle is constructed to determine the actual positions of multiple body parts of each driver and passenger according to the internal space.

[0044] Furthermore, in the embodiment of the present application, when the adaptive adjustment mode is triggered, that is, when the current working condition of the vehicle air conditioner is the adaptive adjustment working condition, the physiological data of each driver and passenger can be collected. Among them, there are various ways to collect physiological data. For example, the image data of the driver and passenger is collected according to the in-vehicle camera to determine the age and gender according to information such as hair color, facial wrinkles, and body shape, determine whether the physiological state is cold according to the purple-red patches caused by frostbite on the exposed skin, determine whether the driver and passenger are in a physiological state of hypoxia, dryness, etc. according to the carbon dioxide concentration and air humidity in the vehicle, and detect the body temperature of the driver and passenger according to the data of the infrared camera.

[0045] The embodiment of the present application can also construct the internal space of the vehicle to three-dimensionalize the space and determine the positions of each driver and passenger in the three-dimensional space, including the position conditions of the body parts of the driver and passenger, so as to more detailedly and specifically determine the target requirements.

[0046] Optionally, in an embodiment of the present application, constructing the internal space of the vehicle includes: obtaining at least two groups of internal image data of the vehicle; taking the corresponding point positions in the at least two groups of internal image data as a reference, and constructing the internal space by combining the reference and the at least two groups of internal image data.

[0047] As a possible implementation manner, the embodiment of the present application can reuse the in-vehicle camera for construction.

[0048] For example, in the embodiment of the present application, the DMS (Driver Monitoring System, cockpit monitoring system) and OMS (Occupancy Monitoring System, passenger detection system) cameras can be combined to form a binocular vision system. Based on the parallax principle and using the imaging device to obtain two images of the object to be measured from different positions, the three-dimensional geometric information of the object is obtained by calculating the position deviation between the corresponding points of the images, that is, taking the corresponding point positions as a reference to construct the internal space of the vehicle.

[0049] Optionally, in an embodiment of the present application, determining the actual positions of multiple body parts of each driver and passenger according to the internal space includes: performing feature matching on the internal image data using preset part features to obtain a matching result; marking multiple body parts of each driver and passenger in the internal image data based on the matching result to obtain internal image data including part labels; and determining the actual positions of the multiple body parts in the internal space using the internal image data including part labels.

[0050] According to the constructed internal space, embodiments of the present application can extract the features of the driver and passengers in the internal image data, then match the extracted features with the conventional human body features to determine the position information of the driver and passengers in the internal space, and mark the body parts in the internal image data, so as to locate the body parts by combining the labels and the position deviation between the two sets of data, and further clarify the distribution of the driver and passengers and the position status of the body parts of the driver and passengers.

[0051] Optionally, in an embodiment of the present application, collecting at least one physiological data of each driver and passenger includes: obtaining the Bluetooth signal data of the vehicle; determining whether there is a wearable device in the vehicle that meets the preset pairing conditions based on the Bluetooth signal data; if there is a wearable device that meets the preset pairing conditions, sending a pairing request, and obtaining at least one physiological data of the corresponding driver and passenger based on the data uploaded by the paired wearable device and the infrared image data of the vehicle.

[0052] When collecting physiological data, embodiments of the present application can collect data in two ways.

[0053] One is the collection of infrared data. By collecting the data inside the vehicle through an infrared camera, physiological information such as the body temperature of each driver and passenger is obtained; the other is the combined collection of infrared data and wearable devices to obtain more accurate physiological information.

[0054] Embodiments of the present application can obtain Bluetooth signal data, pair with the wearable devices of the drivers in the vehicle through Bluetooth. For the paired wearable devices, the vehicle can directly collect the uploaded physiological data, such as heart rate, body temperature, pressure value, blood pressure, height, weight, etc.

[0055] According to the above physiological data, embodiments of the present application can more specifically control the vehicle air conditioner, thereby ensuring the comfort of the drivers and passengers in the vehicle.

[0056] In step S103, calculate the target demand of each driver and passenger according to at least one physiological data and the actual position, and determine the cooling action or heating action of the vehicle air conditioner according to the target demand.

[0057] As a possible implementation manner, embodiments of the present application can evaluate the cooling and heating temperature requirements of the driver and passengers according to physiological data and the actual positions of each part. For example, after determining that the vehicle air conditioner needs to cool or heat, embodiments of the present application can appropriately lower the temperature around the driver or passenger with a too fast heart rate or a relatively high stress value, or direct the air outlet towards the head of the driver or passenger to help the driver or passenger calm down. For the driver or passenger with a relatively large ratio of weight to height, it can be determined that the body type of the driver or passenger is overweight, and the comfortable ambient temperature may be lower than that of others. The temperature around the driver or passenger can be appropriately lowered, or the air outlet can be directed towards the exposed parts (such as arms, head, calves, etc.) of the driver or passenger during cooling, and the air outlet can be avoided from the driver or passenger during heating. For other drivers or passengers sitting next to overweight people, the ambient temperature around them can also be appropriately lowered.

[0058] Optionally, in an embodiment of the present application, calculating the target requirements of each driver and passenger according to at least one physiological data and the actual position includes: matching at least one physiological data with the actual position to obtain a matching result; calculating the target requirements based on the matching result, the external ambient temperature of the vehicle, and the internal ambient temperature of the vehicle.

[0059] When calculating the target requirements, embodiments of the present application can match the physiological data with body parts or the distribution of physiological data of the driver and passengers to clarify data such as the body temperature at positions such as the head, hands, shoulders, and the part in contact with the seat back of the driver and passengers, or clarify the distribution state of the physiological data of the driver and passengers in the internal space. Then, based on the actual temperature of different body parts, different temperature requirements in the vehicle internal space, the external ambient temperature, and the internal ambient temperature of the vehicle, comprehensive calculations are performed to determine the target requirements of each driver and passenger, that is, the target temperature of each area in the internal space.

[0060] Optionally, in an embodiment of the present application, it further includes: updating at least one physiological data, the actual position, the external ambient temperature, and the internal ambient temperature every preset time period; calculating the new target requirements of each driver and passenger based on the updated at least one physiological data, the updated actual position, the updated external ambient temperature, and the updated internal ambient temperature; judging whether the vehicle meets the preset action adjustment condition based on the new target requirements; if the preset action adjustment condition is met, adjusting the cooling action or heating action of the vehicle air conditioner according to the new target requirements.

[0061] In some embodiments, the collected data can be updated every certain time period to judge the temperature adjustment result after the execution of the vehicle air conditioner action in the previous round. If the adjusted temperature does not meet the latest target requirements of the driver and passengers, it is determined that the vehicle meets the action adjustment condition, and a new adjustment can be made to the execution action of the vehicle air conditioner.

[0062] In some other embodiments, by updating data at regular intervals, it is also possible to determine whether the environment inside and outside the vehicle has changed. For example, a sudden change in the outside temperature affects the inside temperature, or there are changes in the number or distribution of passengers in the vehicle. If a change occurs, it can be determined that the vehicle meets the action adjustment condition, and then a new adjustment can be made to the execution actions of the vehicle space to keep the inside of the vehicle always in a comfortable environment.

[0063] Among them, the preset time duration can be set by the vehicle owner himself / herself, or can be set accordingly by those skilled in the art according to the actual situation, and no specific limit is made here.

[0064] Optionally, in an embodiment of the present application, after calculating the target requirements of each passenger, it further includes: matching the corresponding appearance features of each passenger in a preset database based on the external environment temperature and the internal environment temperature; matching the actual features of each passenger with the appearance features to determine whether there is at least one abnormal feature for each passenger; if there is at least one abnormal feature, a corresponding inquiry instruction is generated, and the target requirements are optimized based on the response result of the inquiry instruction or at least one abnormal feature is ignored.

[0065] In addition, for the physical constitution or special needs of each person, the embodiments of the present application can also be identified and differentially processed.

[0066] The embodiments of the present application can determine the conventional appearance features of the people in the vehicle according to the external environment temperature and the internal environment temperature of the vehicle. For example, when the external environment is a cold winter environment, the conventional appearance features of the people in the vehicle should include thick coats, and there may be red patches on the exposed parts such as the nose; when the external environment is a hot environment, the conventional appearance features of the people in the vehicle should be thin clothes, etc. Among them, the appearance features can be obtained through big data and stored in the database for timely calling. The preset database can be placed locally in the vehicle or set in the cloud.

[0067] Using the data collected by the in-vehicle camera, such as internal image data, the actual appearance features of each passenger can be extracted, and the actual appearance features are compared with the appearance features matched with the temperature in the database to determine whether there are abnormal features. For example, in hot weather, if a passenger is wearing thick clothes or covered with a blanket, it can be inferred that the passenger is intolerant to cold and prefers a slightly higher temperature environment; in cold weather, if a passenger is wearing thin clothes, it can be inferred that the passenger prefers a slightly lower temperature environment, etc.

[0068] If there are abnormal features, the embodiments of the present application can initiate an inquiry. For example, it can inquire whether the driver and passengers want to update the temperature adjustment according to the abnormal features, and make corresponding adjustments according to the inquiry result. If the inquiry result is that adjustment is required according to the abnormal features, it controls the vehicle-mounted air conditioner to perform action adjustment. Otherwise, it can ignore the abnormal features and maintain the current action.

[0069] In addition to the above appearance abnormality matching, the embodiments of the present application can also detect various abnormalities by expanding the features of the database. For example, it can determine the abnormal state of the driver and passengers being ill. When a hot compress patch or pain relief patch is recognized from the image data of the driver and passengers, an abnormal feature is generated, and according to the inquiry result, the air outlet of the vehicle-mounted air conditioner can be adjusted to avoid cold air blowing on the painful area.

[0070] Combined with Figure 2 shown, the working principle of the embodiments of the present application is elaborated in detail with an example.

[0071] As Figure 2 shown, the embodiments of the present application include the following steps:

[0072] Step S201: The driver and passengers trigger the function activation button. The embodiments of the present application can receive the trigger button of the adaptive adjustment mode triggered by the driver or passengers in the vehicle. Specifically, it can be adjusted according to the vehicle settings. If the vehicle is set to be triggered only by the driver, other passengers cannot make settings. If the vehicle is set to be freely triggered, the mode can be switched according to any trigger instruction.

[0073] In some embodiments, the adaptive adjustment related requirements of the vehicle-mounted air conditioner can be associated with the vehicle's account information, and the corresponding activation button can be clicked (for example, after the first click to turn on, it is default to remember to turn on, and after the vehicle is ready later, the air conditioner system adaptive adjustment function is default to start).

[0074] After turning on, the embodiments of the present application can attempt to establish communication with the wearable devices of the driver and passengers in the vehicle.

[0075] Step S202: The internal and external temperature sensors and the infrared sensor collect temperature data, the intelligent wearable device provides the physiological data of the driver and passengers (if any), and the in-vehicle binocular camera collects image data. The embodiments of the present application can perform relevant data collection. For example, the internal and external temperature sensors input the internal and external temperatures and transmit them to the intelligent driving data center; the infrared camera and the intelligent wearable device (if any) identify the temperature information of areas such as the head, face, and hands of the driver and passengers, and other physiological information (if any) is transmitted to the intelligent driving data center; the DMS and OMS respectively transmit the images of the driver and passengers' faces, heads, hands, shoulders, instrument panel, deputy instrument panel, steering wheel, and seat backrest to the intelligent driving data center.

[0076] Step S203: The computing unit calculates information such as the 3D positioning information of the driver and passengers and their temperature requirements. The intelligent driving data center infers the 3D positioning information of the driver and passengers' heads, hands, shoulders, and seat backs in the cockpit space, as well as information such as the age and gender of the driver and passengers, by calculating the positions between corresponding points in the image; the intelligent driving data center evaluates the cooling and heating temperature requirements of the driver and passengers through secondary calculation of the input information.

[0077] Step S204: The vehicle-mounted air conditioner performs adjustments related to air temperature, air volume, and air direction.

[0078] Step S205: Perform adaptive adjustment according to the changes in the internal and external environmental temperatures and the physiological information of the driver and passengers. The intelligent driving data center calculates and outputs the cooling and heating requirements of the driver and passengers based on the changes in the temperature environment inside the passenger compartment and in combination with the input from various sensors, and the air conditioning system performs settings for air temperature, air speed, and air direction and automatically makes adaptive adjustments.

[0079] Step S206: Determine whether to turn off / manually adjust the vehicle-mounted air conditioner. If a turn-off instruction or a manual adjustment instruction for the vehicle-mounted air conditioner is received, jump to Step S207; otherwise, jump to Step S202 for adaptive adjustment.

[0080] Step S207: Exit the adaptive adjustment of the vehicle-mounted air conditioner to turn off the vehicle-mounted air conditioner or control the vehicle-mounted air conditioner to perform corresponding actions according to the manual control instruction.

[0081] In summary, the embodiment of the present application utilizes the DMS and OMS cameras in the vehicle to form a binocular stereo vision system. Based on the 3D positioning data of the steering wheel, seat, and the driving posture of the driver in the cockpit, combined with the infrared camera and OMS image recognition technology, by identifying the physiological information such as the gender, age, and body temperature of the driver and other sensor inputs, comprehensively calculate and evaluate the temperature requirements of the driver and passengers. After the mode is activated with one key, the embodiment of the present application can automatically complete the calculation and execute the recommended air conditioning adjustment plan, provide the optimal air conditioning settings, and improve driving safety.

[0082] According to the control method of the vehicle-mounted air conditioner proposed by the embodiments of the present application, when it is detected that the current working condition is the adaptive adjustment working condition, the physiological data of each driver and passenger can be collected, and the internal space of the vehicle can be constructed to determine the actual position of each body part of each driver and passenger according to the internal space. Thus, the target demand of each driver and passenger can be calculated by combining the physiological data and the actual position of the driver and passenger, and the cooling action or heating action of the vehicle-mounted air conditioner can be determined to complete the automatic adjustment of the vehicle-mounted air conditioner.
