Description

Technical Field

[0001] This invention relates to the field of vehicle charging technology, and in particular to a vehicle air conditioning control method, device, readable storage medium, and vehicle. Background Technology

[0002] With the rapid development of society and economy, cars have entered thousands of households. As cars make people's lives more and more convenient, people are paying more and more attention to the functions of vehicles.

[0003] Among them, car air conditioning is one of the vehicle functions that people are paying more and more attention to. Therefore, there are many improvements to car air conditioning in the existing technology. For example, the automatic start of car air conditioning means that when the driver or passenger enters the car and the car engine is started, the air conditioning will be automatically turned on according to the current vehicle environment, such as the temperature inside and outside the car.

[0004] However, when the air conditioning is turned on automatically, most of its operating parameters, such as temperature and airflow, are fixed. This means that the operating parameters are based on the parameters when the air conditioning was last turned off. Under different vehicle conditions, the same operating parameters will give the driver different feelings. For example, with the same operating parameters, the user will feel more comfortable when the vehicle is driving due to heat dissipation and other factors, but will feel hot when the vehicle is idling. Therefore, fixed air conditioning parameters can lead to poor air conditioning experience for the driver or passengers, resulting in a poor vehicle experience. Summary of the Invention

This optimal operating parameter is then used to control the air conditioning system, ensuring a relatively comfortable environment regardless of the vehicle's operating conditions. This improves the user experience. Furthermore, the age range of passengers is taken into account, further enhancing the user experience. Attached Figure Description

[0050] Figure 2 This is a structural block diagram of the vehicle air conditioning control device in the fourth embodiment of the present invention;

[0051] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0052] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0053] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed types.

[0055] The following will describe in detail how to improve the user's vehicle experience when the air conditioner is turned on, with reference to specific embodiments and accompanying drawings.

[0056] Example 1

[0057] Please see Figure 1 The figure shows a vehicle air conditioning control method in the first embodiment of the present invention, the method including steps S10 to S14.

[0058] Step S10: When it is detected that the vehicle needs to turn on the air conditioning, obtain the current passenger information and vehicle operating information.

[0059] When the vehicle's engine starts, the need to turn on the air conditioning can be determined via the air conditioning activation button, or automatically based on real-time environmental monitoring. For example, a temperature sensor inside the vehicle can activate the air conditioning when the engine starts if a high interior temperature is detected. Specifically, the current occupant information includes at least the number of occupants, which may indicate whether the driver is driving alone or with passengers. In practice, image acquisition devices can be installed in the front and rear seats to determine the number of occupants, or pressure sensors can be installed on the seats to determine the number of occupants. Alternatively, image acquisition devices can be installed in the front and rear seats, and pressure sensors can be installed on the seats to determine the number of occupants. Vehicle operating information includes at least the vehicle's operating condition information, which can determine the vehicle's operating status, such as idling, low-speed driving, or high-speed driving.

[0060] Step S11: Obtain subjective evaluation information of the vehicle air conditioning under different operating parameters by different numbers of passengers and different operating conditions.

[0061] Because the air conditioning provides different experiences for drivers and passengers under the same operating parameters, the cooling effect varies depending on the vehicle's operating conditions. For example, the cooling effect at idle speeds differs from that at high speeds. Generally, the cooling capacity at idle is relatively low, and drivers often feel the air conditioning is ineffective. To achieve a more comfortable riding environment, it may be necessary to increase the airflow to ensure a comfortable temperature inside the vehicle. In other words, the purpose of obtaining subjective evaluation information is to determine whether the air conditioning's operating parameters under different vehicle conditions can better meet the needs of the current driver or passengers, or to find relatively comfortable air conditioning operating parameters under different conditions. Specifically, these operating parameters include, but are not limited to, airflow and temperature adjustment.

[0062] In practical implementation, subjective evaluation information is mainly used to obtain the comfort level of the air conditioner under the current operating parameters based on the user's actual experience. This subjective evaluation information can be obtained through user testing according to specific experimental rules; it is an example rather than a limitation. The experimental method can be carried out as follows:

[0063] I. Selection of Test Conditions (including selection of weather, road, time, and vehicle preparation)

[0064] 1. Weather Selection

[0065] 1) Evaluation of air conditioning cooling performance: The test environment temperature range is set to the temperature range where the air conditioner would actually be turned on, for example, above 35℃.

[0066] 2) Evaluation of air conditioning heating performance: The test environment temperature range is set to the temperature range where the air conditioner would actually be turned on, for example, below 5℃.

[0067] 2. Road selection

[0068] 1) Evaluation of air conditioning cooling performance: It is required to select a flat route with little traffic, allowing vehicles to travel at stop-and-go traffic and a speed of 50km / h with safe idling, and a flat and safe route where vehicles can travel at a speed of 100-120km / h for a certain period of time (priority given to highways with little traffic).

[0069] 2) Evaluation of air conditioning heating performance: A flat and uncrowded route that allows vehicles to maintain a speed of 50 km / h and safely idle, and a flat and safe route that allows vehicles to travel at a speed of 100-120 km / h for a certain period of time (prioritizing less congested highways).

[0070] 3. Time Selection

[0071] 1) Evaluation of air conditioning cooling performance: from 11:00 AM to 4:00 PM, and must be completed before 4:00 PM.

[0072] 2) Evaluation of air conditioning heating performance: between 8:00 AM and 10:00 AM, or between 4:00 PM and 6:00 PM.

[0073] 4. Vehicle preparation

[0074] 1) Clean the exterior of the vehicle and both the inside and outside of the windows. Ensure that the area under the seats is clean and free of any foreign objects.

[0075] 2) Check the heating system, ventilation system and air conditioning system for air leaks, whether the ducts / grilles are installed correctly, and whether the blower / temperature and mode control system functions properly.

[0076] 3) Check the engine cooling system for leaks and ensure the coolant level is within acceptable limits. Ensure the engine cooling fan is functioning properly.

[0077] 4) Check the front grille, condenser / radiator for dirt or blockage, and check that the front seal is installed correctly.

[0078] 5) Evacuate the entire A / C system and maintain the vacuum state before refilling the refrigerant.

[0079] 6) Check the climate control heating system channels and check the vehicle body for leaks. The air intake and exhaust ports should be checked for blockages.

[0080] II. Test run and evaluation record:

[0081] Test officially launched:

[0082] 1) All evaluators must spend a full 5 minutes in the surrounding environment before the test begins. The driver must board first. Check the test vehicle and evaluator seating positions. Once inside the vehicle, close the doors to minimize heat loss. Each evaluator should enter the vehicle as quickly as possible. Each evaluator must carry a subjective evaluation form for the air conditioning cooling performance and record the start time.

[0083] 2) Once the signal from the timekeeper is received, start the engine and set the air conditioning operating parameters according to the predetermined requirements. Then begin driving along the predetermined route and under the predetermined operating conditions. All evaluators will then fill out the subjective evaluation form for the air conditioning cooling performance.

[0084] Finally, we will obtain subjective evaluation information under different operating parameters and conditions of the air conditioner, which can determine under what operating parameters the air conditioner performs more comfortably under different conditions.

[0085] Step S12: Determine the optimal operating parameters of the vehicle air conditioner under different operating conditions of the vehicle after the vehicle is carrying different numbers of passengers, based on the subjective evaluation information.

[0086] Specifically, subjective evaluation information generally includes the user's evaluation of the current comfort level of the air conditioner, such as quite uncomfortable, moderately uncomfortable, comfortable, extremely comfortable, etc. Based on the comfort level filled in by the user, the optimal operating parameters of the air conditioner under a certain operating condition can be determined. Alternatively, for each established standard of comfort level, passengers can score the performance of the air conditioner under a certain operating parameter under the current operating condition, and the optimal operating parameters under the current operating condition can be determined based on the score.

[0087] Step S13: Determine the number of current passengers and the operating condition of the vehicle based on the current passenger information and vehicle operating information, respectively.

[0088] Specifically, under the same operating parameters, the cooling effect of the air conditioner on the vehicle interior varies depending on the number of passengers. To improve the accuracy of determining the optimal operating parameters of the air conditioner, the comfort level of the air conditioner under different operating parameters can be evaluated based on the number of passengers during the test. Subsequently, the optimal operating parameters can be selected based on the corresponding number of passengers. Furthermore, the vehicle's operating information can determine the current operating condition of the vehicle, such as idling, low-speed driving, or high-speed driving.

[0089] Specifically, in some optional embodiments of the present invention, the step of determining the number of current passengers and the operating condition of the vehicle based on the current passenger information and the vehicle operating information includes:

[0090] The system acquires image data from an image acquisition device installed inside the vehicle and pressure information from pressure sensors installed inside the vehicle seats; and determines the number of passengers based on the image data and pressure information.

[0091] The vehicle is equipped with image acquisition devices, such as cameras, in both the front and rear rows. These devices can capture images of the occupants inside the vehicle. Specifically, the image acquisition devices can be activated to capture images of the interior after the doors are opened and closed and the vehicle is powered on, and then deactivated after the images are captured. Pressure sensors are installed on the seats to collect pressure information. The number of occupants in the vehicle is determined based on the image data collected by the image acquisition devices and the pressure information collected by the pressure sensors.

[0092] It should be noted that pressure sensors can collect pressure information from the vehicle seats to determine the current occupants. However, relying solely on pressure information collected by pressure sensors may lead to misjudgments. For example, when a significant object is placed on the seat, its weight may be close to that of a normal human body, causing the pressure sensor to mistakenly identify a passenger as seated. Image acquisition devices can collect image data from inside the vehicle to determine the number of occupants. However, relying solely on image data collected by image acquisition devices may also lead to misjudgments. For instance, the image acquisition device may not be able to capture the seat where the occupants are seated, or the occupants' height or the limited angle of the image acquisition device may prevent the acquisition of image data of the occupants. Therefore, in this embodiment of the invention, the number of occupants is determined by combining the image data collected by the image acquisition device and the pressure information collected by the pressure sensor.

[0093] Furthermore, in some optional embodiments of the present invention, the step of acquiring image data collected by an image acquisition device installed inside the vehicle and pressure information collected by a pressure sensor installed inside the vehicle seat, and determining the number of passengers based on the image data and pressure information, includes:

[0094] Acquire image data from image acquisition devices installed inside the vehicle and pressure information from pressure sensors installed inside the vehicle seats;

[0095] The number of the first passenger and the number of the second passenger in the vehicle are determined based on the image data and pressure information, respectively.

[0096] Determine whether the number of the first passenger and the number of the second passenger are equal;

[0097] If so, then the number of the first passenger or the number of the second passenger shall be taken as the number of passengers.

[0098] If not, the target seat causing the quantity deviation is determined based on the image data and pressure information, and the image acquisition device responsible for acquiring the target seat is controlled to adjust its angle and acquire the image of the target seat. The number of the first passenger is corrected based on the image acquisition results to determine the number of passengers.

[0099] Understandably, the number of first passengers determined by image data and the number of second passengers determined by pressure information can be determined based on image data and pressure information, respectively. When the two numbers are equal, it indicates that there are no errors in the information collected by the image data and pressure information; that is, either determined number of passengers is the current number of passengers. However, when the two numbers are not equal, it indicates that there is an error in the data. For example, the number determined by the image data may be inaccurate due to the height of the passengers or the acquisition angle of the image acquisition device, or the number of passengers determined by the pressure information collected by the pressure sensor may be inaccurate due to the presence of heavy objects in the rear of the vehicle. Based on this, the target seat where the number deviation occurs can be identified. This is because pressure sensors and pressure sensors are installed under each seat in the vehicle. Each seat is equipped with an image acquisition device. Therefore, it is possible to determine which seat the acquired number of occupants in the vehicle comes from, thus identifying the seat causing the quantity error. For example, if the pressure sensor determines that the current seat is occupied, but the image acquisition device determines that the current seat is empty, or vice versa, the image acquisition device responsible for acquiring the target seat can be adjusted in angle to re-acquire the image of the target seat. Based on the acquisition result, it can be determined whether the current seat is occupied, thereby determining the final number of occupants. For example, if the current seat is empty, the previous acquisition result is retained, and the first number of occupants is taken as the current number of occupants in the vehicle. If the current seat is occupied, the current number of occupants is summed with the first number of occupants to obtain the current number of occupants in the vehicle.

[0100] Furthermore, in some optional embodiments of the present invention, the step of acquiring image data collected by an image acquisition device installed inside the vehicle and pressure information collected by a pressure sensor installed inside the vehicle seat, and determining the number of passengers based on the image data and pressure information, includes:

[0101] Acquire image data from image acquisition devices installed inside the vehicle and pressure information from pressure sensors installed inside the vehicle seats;

[0102] The occupant type of each seat in the vehicle is determined based on the image data, and the pressure threshold of each seat is determined based on the occupant type.

[0103] Step S14: Determine the current operating parameters of the vehicle based on the number of passengers and the optimal operating parameters corresponding to the vehicle's current operating condition.

[0104] Specifically, the optimal operating parameters, the corresponding number of passengers, and the vehicle's operating conditions can be stored in the vehicle in advance in the form of a mapping table. After determining the current number of passengers and the vehicle's operating conditions, the optimal operating parameters are obtained from the mapping table and used as the current operating parameters of the vehicle's air conditioning.

[0105] Step S15: When the vehicle air conditioner is turned on, control the vehicle air conditioner using the vehicle's current operating parameters.

[0106] The operating parameters include at least the air conditioning air volume and the current air conditioning temperature. When the vehicle air conditioning is turned on by a button, the air conditioning will adjust the air conditioning air volume and temperature to the corresponding values ​​according to the current operating parameters. When the vehicle air conditioning is turned on automatically, after sensing that the vehicle needs to turn on the air conditioning, the air conditioning will be turned on and the air conditioning air volume and temperature will be adjusted to the corresponding values ​​according to the current operating parameters.

[0107] In summary, the vehicle air conditioning control method in the above embodiments of the present invention obtains information about the people inside the vehicle and the vehicle's operating information when it is detected that the vehicle needs to turn on the air conditioning. It then obtains the optimal operating parameters of the air conditioning based on the subjective evaluation information of different numbers of air conditioning users on the vehicle air conditioning under different operating conditions and different operating parameters. Finally, it determines the current optimal operating parameters of the vehicle air conditioning based on the number of people and the vehicle operating conditions determined by the personnel information and vehicle operating information, and uses these operating parameters as the current operating parameters of the air conditioning to control the vehicle air conditioning. This ensures that the vehicle air conditioning can provide a relatively comfortable environment when the vehicle is in any operating condition, thereby improving the user experience.

[0108] Example 2

[0109] This invention also proposes a vehicle air conditioning control method. The difference between the vehicle air conditioning control method in this embodiment and the vehicle air conditioning control method proposed in Embodiment 1 is as follows:

[0110] Step S12 includes:

[0111] Based on the subjective evaluation information, determine the favorability of different numbers of passengers towards the vehicle's air conditioning under different operating parameters when the vehicle is in different operating conditions;

[0112] The average favorability is determined based on the number of passengers and their favorability, and the working parameters corresponding to the subjective evaluation information with the highest average favorability are taken as the optimal working parameters of the vehicle under the current working conditions.

[0113] Subjective evaluation information mainly includes users' evaluations of the current vehicle air conditioning operation during testing. Generally, during testing, users can score the comfort of the current vehicle air conditioning operation based on multiple predetermined indicators. The specific scores reflect the user's satisfaction. The average satisfaction level under a certain operating condition and a certain operating parameter is determined based on the satisfaction level of each passenger during the test and the number of passengers during the test. By repeating the test in this way, the average satisfaction level under different operating parameters under a certain operating condition can be obtained, and the operating parameter corresponding to the highest average satisfaction level is taken as the optimal operating parameter.

[0114] Furthermore, in some optional embodiments of the present invention, to further improve the accuracy of the average favorability calculation, after the step of determining the favorability of different numbers of passengers towards the vehicle air conditioning under different operating parameters based on the subjective evaluation information, the method further includes:

[0115] Determine whether there is a biased favorability among the multiple favorability ratings that differs from other favorability ratings by a difference threshold;

[0116] If so, the deviation in favorability is removed, and then the steps of determining the average favorability based on the number of passengers and the favorability, and taking the working parameter corresponding to the subjective evaluation information with the highest average favorability as the optimal working parameter of the vehicle under the current working conditions are executed.

[0117] Specifically, the difference in favorability scores can be used to determine whether there are any biased favorability scores that differ significantly from other favorability scores. If biased favorability scores are found, they can be removed before calculating the average favorability score. This avoids the problem of inaccurate average favorability calculations caused by personal reasons during testing (such as the tester being unwell).

[0118] In summary, the vehicle air conditioning control method in the above embodiments of the present invention obtains information about the people inside the vehicle and the vehicle's operating information when it is detected that the vehicle needs to turn on the air conditioning. It then obtains the optimal operating parameters of the air conditioning based on the subjective evaluation information of different numbers of air conditioning users on different operating parameters of the vehicle air conditioning under different vehicle operating conditions. Finally, it determines the current optimal operating parameters of the vehicle air conditioning based on the number of people and the vehicle operating conditions determined by the personnel information and vehicle operating information, and uses these operating parameters as the current operating parameters of the air conditioning to control the vehicle air conditioning. This ensures that the vehicle air conditioning can provide a relatively comfortable environment when the vehicle is in any operating condition, thus improving the user experience. Furthermore, it takes into account the age group of passengers, further enhancing the user experience.

[0119] Example 3

[0120] This embodiment also proposes a vehicle air conditioning control method. The difference between the vehicle air conditioning control method proposed in this embodiment and the vehicle air conditioning control method proposed in Embodiment 1 is as follows:

[0121] Step S11 includes:

[0122] The system collects subjective evaluation information of the vehicle's air conditioning under different operating parameters by passengers of different ages and numbers, and by passengers of different ages and numbers under different operating conditions.

[0123] Step S12 includes:

[0124] Based on the current passenger information and vehicle operating information, determine the number of current passengers, their age group, and the vehicle's operating condition.

[0125] Step S13 includes:

[0126] Based on the subjective evaluation information, the optimal operating parameters of the vehicle air conditioner under different operating conditions of the vehicle after carrying passengers of different age groups and different numbers are determined.

[0127] Step S14 includes:

[0128] The current operating parameters of the vehicle are determined based on the number of current passengers, the age range of the current passengers, and the optimal operating parameters corresponding to the vehicle's current operating conditions.

[0129] Understandably, in this embodiment, when collecting subjective evaluation information and determining the optimal operating parameters, the age range of the passengers being tested is taken into account. After the test, the evaluation of the car air conditioner under different operating parameters by different age groups and different numbers of passengers will be obtained. Furthermore, the age range of the passengers is obtained when the air conditioner is turned on, and the corresponding optimal operating parameters are determined based on the age range and number of passengers. This is equivalent to adding an extra factor to ensure that the air conditioner is turned on in a way that better meets the needs of the current passengers. The age range of the passengers can be determined by image information collected by the in-vehicle image acquisition device.

[0130] It should be noted that the methods for subjective evaluation of car air conditioning by passengers of different ages and numbers, as well as how to determine the optimal operating parameters, are largely the same as those in Example 1, and will not be repeated here.

[0131] In summary, the vehicle air conditioning control method in the above embodiments of the present invention obtains information about the people inside the vehicle and the vehicle's operating information when it is detected that the vehicle needs to turn on the air conditioning. It then obtains the optimal operating parameters of the air conditioning based on the subjective evaluation information of different numbers of air conditioning users on different operating parameters of the vehicle air conditioning under different vehicle operating conditions. Finally, it determines the current optimal operating parameters of the vehicle air conditioning based on the number of people and the vehicle operating conditions determined by the personnel information and vehicle operating information, and uses these operating parameters as the current operating parameters of the air conditioning to control the vehicle air conditioning. This ensures that the vehicle air conditioning can provide a relatively comfortable environment when the vehicle is in any operating condition, thus improving the user experience. Furthermore, it takes into account the age group of passengers, further enhancing the user experience.

[0132] Example 4

[0133] Please see Figure 2 The image shows a vehicle air conditioning control device proposed in the fourth embodiment of the present invention, the device comprising:
