Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
An air outlet control method of a vehicle air conditioning system, a computer readable storage medium, and an air outlet control device of a vehicle air conditioning system according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an air outlet control method of a vehicle air conditioning system according to an embodiment of the present invention.
As shown in fig. 1, the method for controlling the air outlet of the vehicle air conditioning system according to the embodiment of the invention may include the following steps:
s1, when a vehicle air conditioning system is started, determining the temperature of the outside environment and the temperature of the air outlet in the vehicle.
Specifically, generally after the vehicle is electrified, an air conditioning system of the vehicle can be automatically started, manual operation of a user is not needed, user experience is improved, and the vehicle is intelligent. The means for acquiring the outside environment temperature includes various means such as acquiring the outside environment temperature by a temperature sensor provided on the vehicle; for another example, the current position information is positioned through a GPS system on the vehicle-mounted terminal, and the vehicle-outside environment temperature corresponding to the current position information is automatically generated; for another example, when the user enters the vehicle, the vehicle-mounted terminal and the user mobile terminal automatically establish communication connection, and the weather information on the user mobile terminal is acquired to determine the temperature outside the vehicle, and of course, the acquisition modes of the temperature outside the vehicle are various and are not limited to the listed modes. The method for acquiring the air outlet temperature in the vehicle can be as follows: the temperature sensor arranged at the air outlet is used for acquiring the air outlet temperature in the vehicle, wherein when the number of the air outlets is one, the temperature of the air outlet can be directly used as the air outlet temperature in the vehicle, when a plurality of air outlets are arranged, one temperature sensor can be arranged at each air outlet so as to acquire the air outlet temperature of the corresponding air outlet, then the average value of all the air outlet temperatures is used as the air outlet temperature in the vehicle, or the maximum value and the minimum value are removed, and the average value of the rest air outlet temperatures is used as the air outlet temperature in the vehicle.
S2, controlling an air outlet mode of the vehicle air conditioning system according to the temperature outside the vehicle and the temperature outside the vehicle, wherein the air outlet mode comprises a plurality of modes of face blowing, foot blowing, face blowing and foot blowing and window blowing.
In one embodiment of the present invention, the face blowing mode is generally blowing through the outlets at the center and both sides of the vehicle instrument desk; the foot blowing mode generally blows air through an air outlet below an instrument desk of the vehicle; the face and foot blowing mode is generally to blow air through air outlets in the center and on two sides of an instrument desk of a vehicle and air outlets below the instrument desk; the foot-blowing window-blowing mode is generally the blowing of air through the air outlet below the vehicle instrument desk and the air outlet below the vehicle window.
Specifically, after the outdoor environment temperature and the air-out temperature in the vehicle are obtained through the step S1, the two temperature values are judged, and the corresponding air-out mode is determined according to the magnitude of the temperature values, so that the comfort of the environment where the driver and the personnel in the vehicle are located is improved on the premise of ensuring the driving safety of the driver. For example, when the temperature of the air outlet in the vehicle is very high and the temperature of the air outlet outside the vehicle is low, the situation that frosting is easy to occur on the vehicle window is indicated, if the frosting cannot be timely performed, the driving of a driver can be influenced, potential safety hazards exist, the air outlet mode can be controlled to be a foot-blowing and window-blowing mode, and under the condition that the frosting on the vehicle window is removed, the comfort of feet of a user can be ensured, so that the reaction speed of feet is relatively high. For another example, when the air outlet temperature in the vehicle is low, a face blowing mode is selected, so that the face of the user is preferentially kept cool, the user is enabled to be conscious, and the driving safety is improved.
In conclusion, through the size of indoor air-out temperature and the size of car outside environment temperature, the automatic switch-over different air-out modes need not the manual operation of user, and degree of automation is higher to guaranteed user's travelling comfort, generally speaking, user's travelling comfort principle is head cool foot warm.
According to one embodiment of the present invention, controlling an air outlet mode of a vehicle air conditioning system according to an outside air temperature and an inside air outlet temperature of a vehicle includes: and controlling the vehicle air conditioning system to enter a corresponding air outlet mode and switching modes according to the temperature of the outside environment and the temperature of the air outlet in the vehicle.
That is, not only the entering air-out mode can be determined according to the in-vehicle environment temperature and the in-vehicle air-out temperature, but also the air-out mode can be switched according to the current air-out mode and the in-vehicle environment temperature, for example, when the current air-out mode is the face-blowing mode, if the indoor air-out temperature becomes high, the face-blowing mode can be switched to the face-blowing foot-blowing mode; for another example, when the current air-out mode is the foot blowing mode, if the air-out temperature in the vehicle becomes low, the foot blowing mode may be switched to the foot blowing window blowing mode.
How to automatically select the air-out mode according to the outside air temperature and the inside air outlet temperature is described in detail below.
According to one embodiment of the present invention, controlling a vehicle air conditioning system to enter a corresponding air outlet mode according to an outside air temperature and an inside air outlet temperature of a vehicle includes: when the air outlet temperature in the vehicle is smaller than the first preset temperature, controlling the vehicle air conditioning system to enter a face blowing mode; when the air outlet temperature in the vehicle is greater than or equal to the first preset temperature and less than or equal to the fourth preset temperature, controlling the vehicle air conditioning system to enter a face and foot blowing mode; when the air outlet temperature in the vehicle is greater than the fourth preset temperature and less than or equal to the fifth preset temperature, if the external environment temperature of the vehicle is less than the preset environment temperature threshold value, controlling the vehicle air conditioning system to enter a foot-blowing and window-blowing mode; when the air outlet temperature in the vehicle is greater than the fourth preset temperature and less than or equal to the fifth preset temperature, if the temperature outside the vehicle is greater than or equal to a preset environmental temperature threshold value, controlling the vehicle air conditioning system to enter a foot blowing mode; when the air outlet temperature in the vehicle is higher than the fifth preset temperature, controlling the vehicle air conditioning system to enter a foot blowing mode. The first preset temperature T1, the fourth preset temperature T4, the fifth preset temperature T5 and the preset environmental temperature threshold T can be calibrated according to actual conditions, wherein T1 is smaller than T4 and smaller than T5.
Specifically, at the initial stage of the power-on operation of the air conditioning system, the temperature T ' of the air outlet in the vehicle is detected in real time, and the magnitude of the T ' is judged, wherein when the T ' is smaller than T1, the current temperature in the vehicle is lower, and in order to follow the principle of comfort of users, the air conditioning system is controlled to operate in a face blowing mode, namely, the air outlets in the center and the two sides of the instrument desk of the vehicle are controlled to start to outlet air, and correspondingly, in order to reduce energy consumption, the air outlet below the instrument desk of the vehicle and the air outlet below the window of the vehicle are not provided with air. When T' is greater than or equal to T1 and less than or equal to T4, the temperature in the vehicle is proper, and in order to follow the principle of user comfort, the air conditioning system is controlled to operate in a face blowing and foot blowing mode, namely, the air outlets at the center and the two sides of the instrument desk of the vehicle and the air outlets below the instrument desk are controlled to blow, and correspondingly, in order to reduce energy consumption, the air outlets below the vehicle window cannot blow. When T' is greater than T5, the air conditioning system is controlled to operate in a foot blowing mode, namely, the air outlets below the vehicle instrument desk are controlled to blow, and accordingly, in order to reduce energy consumption, the air outlets at the center and the two sides of the vehicle instrument desk and the air outlets below the vehicle window are not blown.
When T ' is greater than or equal to T4 and less than or equal to T5, the temperature in the vehicle is higher, such as when the heating mode is started in winter, the comfort of the feet of the user is preferentially ensured under the condition, and the situation of frosting of the vehicle window is also required to be considered because the outdoor temperature in winter is lower, so the temperature T ' outside the vehicle is also detected in real time, and the size of the T ' is judged. If T' is smaller than T, it indicates that the temperature outside the vehicle is lower, and when the temperature difference between the inside and the outside of the vehicle is larger, the vehicle window is easy to frost, at this time, in order to improve the driving safety, and simultaneously ensure the comfort of the user, the air conditioning system is controlled to operate in a foot-blowing window mode, namely, the air outlet below the vehicle instrument desk and the air outlet below the vehicle window are controlled to blow, and accordingly, in order to reduce the energy consumption, the air outlet at the center and the two sides of the vehicle instrument desk is not blown. If T' is greater than or equal to T, the temperature difference between the interior and the exterior of the automobile is not low, and the frosting of the automobile window is avoided, so that the energy consumption is saved, the comfort of a user is ensured, the air conditioning system is controlled to operate in a foot blowing mode, namely, the air outlet below the automobile instrument desk is controlled to blow, and correspondingly, the air outlet in the center and the two sides of the automobile instrument desk and the air outlet below the automobile window are not blown in order to reduce the energy consumption.
It should be noted that the above listed temperature intervals may be set according to actual conditions, and the remaining intervals have hysteresis, and the air outlet mode corresponds to the air outlet temperature one by one. For example, as shown in fig. 2, when T' is greater than T1 and less than the second preset temperature T2, the air-out mode of the air-conditioning system may be selected to be a face-blowing mode or a foot-blowing mode, and the air-out mode is determined according to the set correspondence between the air-out mode and the air-out temperature.
Therefore, the air outlet control method can automatically select the corresponding air outlet mode according to the temperature inside and outside the automobile, ensures the comfort of the user to the greatest extent, ensures the driving safety of the user at the same time, does not need manual operation of the user, and has higher degree of automation.
The following describes in detail how the present invention automatically switches the air-out mode according to the outside air temperature and the inside outlet temperature.

Corresponding to the embodiment, the invention further provides an air outlet control device of the vehicle air conditioning system.
Fig. 6 is a block diagram schematically illustrating an air outlet control apparatus of a vehicle air conditioning system according to an embodiment of the present invention.
As shown in fig. 6, an air outlet control device 200 of a vehicle air conditioning system according to an embodiment of the present invention may include: a determination module 210 and a control module 220.
The determining module 210 is configured to determine an outside environment temperature and an inside air outlet temperature when the vehicle air conditioning system is turned on. The control module 220 is configured to control an air-out mode of the vehicle air conditioning system according to an outside air temperature and an inside air-out temperature, where the air-out mode includes a plurality of modes of a face-blowing mode, a foot-blowing mode, a face-blowing foot-blowing mode, and a foot-blowing window-blowing mode.
Specifically, generally after the vehicle is electrified, an air conditioning system of the vehicle can be automatically started, manual operation of a user is not needed, user experience is improved, and the vehicle is intelligent. The means for acquiring the outside environment temperature includes various means such as acquiring the outside environment temperature by a temperature sensor provided on the vehicle; for another example, the current position information is positioned through a GPS system on the vehicle-mounted terminal, and the vehicle-outside environment temperature corresponding to the current position information is automatically generated; for another example, when the user enters the vehicle, the vehicle-mounted terminal and the user mobile terminal automatically establish communication connection, and the weather information on the user mobile terminal is acquired to determine the temperature outside the vehicle, and of course, the acquisition modes of the temperature outside the vehicle are various and are not limited to the listed modes. The method for acquiring the air outlet temperature in the vehicle can be as follows: the temperature sensor arranged at the air outlet is used for acquiring the air outlet temperature in the vehicle, wherein when the number of the air outlets is one, the temperature of the air outlet can be directly used as the air outlet temperature in the vehicle, when a plurality of air outlets are arranged, one temperature sensor can be arranged at each air outlet so as to acquire the air outlet temperature of the corresponding air outlet, then the average value of all the air outlet temperatures is used as the air outlet temperature in the vehicle, or the maximum value and the minimum value are removed, and the average value of the rest air outlet temperatures is used as the air outlet temperature in the vehicle.
In one embodiment of the present invention, the face blowing mode is generally blowing through the air outlets in the center and at both sides of the vehicle instrument desk; the foot blowing mode generally blows air through an air outlet below an instrument desk of the vehicle; the face and foot blowing mode is generally to blow air through air outlets in the center and on two sides of an instrument desk of a vehicle and air outlets below the instrument desk; the foot-blowing window-blowing mode is generally the blowing of air through the air outlet below the vehicle instrument desk and the air outlet below the vehicle window.
After the outdoor environment temperature and the air-out temperature in the vehicle are obtained, the two temperature values are judged, and the corresponding air-out mode is determined according to the temperature values, so that the comfort of the environment where the driver and the personnel in the vehicle are located is improved on the premise of ensuring the driving safety of the driver. For example, when the temperature of the air outlet in the vehicle is very high and the temperature of the air outlet outside the vehicle is low, the situation that frosting is easy to occur on the vehicle window is indicated, if the frosting cannot be timely performed, the driving of a driver can be influenced, potential safety hazards exist, the air outlet mode can be controlled to be a foot-blowing and window-blowing mode, and under the condition that the frosting on the vehicle window is removed, the comfort of feet of a user can be ensured, so that the reaction speed of feet is relatively high. For another example, when the air outlet temperature in the vehicle is low, a face blowing mode is selected, so that the face of the user is preferentially kept cool, the user is enabled to be conscious, and the driving safety is improved.
In one embodiment of the invention, the entering air-out mode can be determined according to the environmental temperature in the vehicle and the air-out temperature in the vehicle, and the air-out mode can be switched according to the current air-out mode and the environmental temperature in the vehicle, for example, when the current air-out mode is a face-blowing mode, if the indoor air-out temperature becomes high, the face-blowing mode can be switched to a face-blowing foot-blowing mode; for another example, when the current air-out mode is the foot blowing mode, if the air-out temperature in the vehicle becomes low, the foot blowing mode may be switched to the foot blowing window blowing mode.
Specifically, at the initial stage of the power-on operation of the air conditioning system, the temperature T ' of the air outlet in the vehicle is detected in real time, and the magnitude of the T ' is judged, wherein when the T ' is smaller than T1 (first preset temperature), the current temperature in the vehicle is lower, and in order to follow the principle of user comfort, the air conditioning system is controlled to operate in a face blowing mode, namely, the air outlets in the center and at the two sides of the vehicle instrument desk are controlled to start to air outlet, and correspondingly, in order to reduce energy consumption, the air outlet below the vehicle instrument desk and the air outlet below the vehicle window cannot air outlet. When T' is greater than or equal to T1 and less than or equal to T4 (fourth preset temperature), the temperature in the vehicle is proper, and in order to follow the principle of user comfort, the air conditioning system is controlled to operate in a face blowing and foot blowing mode, namely, the air outlets in the center and two sides of the instrument desk of the vehicle and the air outlets below the instrument desk are controlled to blow, and correspondingly, in order to reduce energy consumption, the air outlets below the vehicle window cannot blow. When T' is greater than T5 (fifth preset temperature), the air conditioning system is controlled to operate in a foot blowing mode, namely, the air outlets below the vehicle instrument desk are controlled to blow, and accordingly, in order to reduce energy consumption, the air outlets at the center and the two sides of the vehicle instrument desk and the air outlets below the vehicle window are not blown.
When T ' is greater than or equal to T4 and less than or equal to T5, the temperature in the vehicle is higher, such as when the heating mode is started in winter, the comfort of the feet of the user is preferentially ensured under the condition, and the situation of frosting of the vehicle window is also required to be considered because the outdoor temperature in winter is lower, so the temperature T ' outside the vehicle is also detected in real time, and the size of the T ' is judged. If T' is smaller than T, it indicates that the temperature outside the vehicle is lower, and when the temperature difference between the inside and the outside of the vehicle is larger, the vehicle window is easy to frost, at this time, in order to improve the driving safety, and simultaneously ensure the comfort of the user, the air conditioning system is controlled to operate in a foot-blowing window mode, namely, the air outlet below the vehicle instrument desk and the air outlet below the vehicle window are controlled to blow, and accordingly, in order to reduce the energy consumption, the air outlet at the center and the two sides of the vehicle instrument desk is not blown. If T' is greater than or equal to T, the temperature difference between the interior and the exterior of the automobile is not low, and the frosting of the automobile window is avoided, so that the energy consumption is saved, the comfort of a user is ensured, the air conditioning system is controlled to operate in a foot blowing mode, namely, the air outlet below the automobile instrument desk is controlled to blow, and correspondingly, the air outlet in the center and the two sides of the automobile instrument desk and the air outlet below the automobile window are not blown in order to reduce the energy consumption.
It should be noted that the above listed temperature intervals may be set according to actual conditions, and the remaining intervals have hysteresis, and the air outlet mode corresponds to the air outlet temperature one by one. For example, as shown in fig. 2, when T' is greater than T1 and less than the second preset temperature T2, the air-out mode of the air-conditioning system may be selected to be a face-blowing mode or a foot-blowing mode, and the air-out mode is determined according to the set correspondence between the air-out mode and the air-out temperature.

If T' is smaller than T3, automatically switching the foot blowing mode into a foot blowing face blowing mode, namely controlling air outlets at the center and at two sides of the vehicle instrument desk to discharge air, and keeping the air outlet below the vehicle instrument desk from discharging air; if T' is greater than or equal to T3, the current air-out mode is kept unchanged, namely the air-out of the air-out openings below the vehicle instrument desk is kept, the air-out openings in the center and the two sides of the vehicle instrument desk are not blown, and the air-out openings below the vehicle window are not blown.
When the temperature of the air outlet in the automobile suddenly changes, the air outlet is restrained by adopting a first-order lag filtering algorithm, so that the air outlet reaches a stable value, wherein the smaller the filtering coefficient is, the better the filtering effect is, but the slower the speed of reaching the stable value is, so that the proper filtering coefficient can be selected according to actual conditions, and the stable value can be quickly reached while the filtering effect is ensured.

For another example, it is determined whether the passenger is present in the rear left seat, whether the passenger is present in the rear right seat, and whether the passenger is present in the main driver seat. For another example, it is determined whether an occupant is present in the main driver seat, then it is determined whether an occupant is present in the passenger seat, then it is determined whether an occupant is present in the rear right seat, and finally it is determined whether an occupant is present in the rear left seat.
The air outlet direction of the air outlet is adjusted according to the body shape, the face position and the foot position of the passenger in the vehicle, so that the optimal air blowing direction is ensured, and the comfort of the human body is improved. Specifically, the air conditioning system is powered on. The face blowing air door and the foot blowing air door corresponding to the main driver seat are set to be at default positions or memory positions, the face blowing air door and the foot blowing air door corresponding to the auxiliary driver seat are set to be at default positions or memory positions, the face blowing air door and the foot blowing air door corresponding to the rear left seat are set to be at default positions or memory positions, and the face blowing air door and the foot blowing air door corresponding to the rear right seat are set to be at default positions or memory positions. When a face blowing air door on a current seat is opened, judging whether the active area of the face of an occupant in t1 (first preset time) is smaller than S1 (first preset value), and if so, aligning the blowing direction of the face blowing air door to the center of the face active area; if not, blowing according to the default position. When a foot blowing air door on a current seat is opened, judging whether an activity area of feet of an occupant in t2 (second preset time) is smaller than S2 (second preset value) or not, if yes, judging whether the number of the foot blowing air openings is larger than a set value (2), if yes, distributing the foot blowing air doors according to the proportion, and aligning the blowing direction of the foot blowing air doors to the center of the foot activity area; if not, the blowing direction of the foot blowing air door is aligned to the middle of the two feet according to the distance between the two feet.
The above-mentioned manner of determining whether the face and the feet of the occupant are in the active region may be: the face of the passenger is collected through the camera, the facial features are extracted, the localization of the facial features of the passenger in a period of time is judged, and if the position change does not exceed a certain value, the moving area is considered to be smaller than a set value. Similarly, the feet of the passenger are collected through the camera, the foot characteristics are extracted, the foot characteristics of the passenger are judged to be positioned within a period of time, and if the position change does not exceed a certain value, the movement area is considered to be smaller than a set value.
In addition, the above-mentioned order of judging whether the foot-blowing tuyere is opened or not and whether the face-blowing tuyere is opened or not is not limited to the order in the above-mentioned embodiment, and it may be judged whether the foot-blowing tuyere is opened or not first or whether the face-blowing tuyere is opened or not first. When the active area of the face of the passenger in the time t1 is greater than or equal to S1, the air outlet direction can be kept to be a default position; when the movement area of the foot of the passenger in the time t2 is greater than or equal to S2, the air outlet direction can be kept to be the default position.
