Priority is claimed on Chinese Patent Application No. 202310898577.8, filed on Jul. 20, 2023, the contents of which are incorporated herein by reference.
The present invention relates to the technical field of air conditioning of a vehicle, in particular to a method and device for controlling an air conditioning outlet of a vehicle, a vehicle, a computing device, and a computer-readable storage medium.
There are usually a plurality of air conditioning outlets on an existing vehicle, and if all air outlet directions thereof are manually controlled by passengers, the operation is cumbersome.
Based on this, methods for automatically controlling an air conditioning outlet are proposed, and one method thereof is as follows: analyzing, according to temperatures inside and outside a vehicle, a temperature of an air outlet, and a voltage of an air blower, to acquire a target opening angle of each air conditioning outlet in the vehicle, and controlling an opening angle of each air conditioning outlet to be the corresponding target opening angle, thereby allowing passengers to feel temperature rise or temperature falling in a short time, and the user experience is improved. However, the method has the following technical problem: a direction of the air conditioning outlet is adjusted only according to the temperatures inside and outside the vehicle and an air volume of the air blower, and a difference between people is not taken into consideration, that is, actual requirements of different passengers are not taken into consideration, so that the user experience is poor.
Another method is as follows: acquiring, when an in-vehicle air conditioner operates, environmental characteristic parameters inside a vehicle and temperature characteristic parameters of a passenger; determining whether the body feeling of the passenger satisfies the thermal comfort according to the environmental characteristic parameters inside the vehicle and the temperature characteristic parameters of the passenger; acquiring a face position of the passenger; and controlling an air direction of the in-vehicle air conditioning outlet according to a determination result and the face position of the passenger. In this manner, the air direction of the air conditioning outlet can be automatically determined according to the face position of the passenger, so that the thermal comfort of the passenger is ensured, thereby achieving an efficient air direction adjustment. However, the method has the following technical problem: the body feeling of the passenger is determined according to a temperature and a humidity inside the vehicle and a temperature of the face and clothes of the passenger, and a machine learning model is established through learning of a robot so as to acquire the determination result of whether the body feeling is comfortable. The method also does not take into consideration of the difference between people, that is, does not take into consideration of the actual requirements of different passengers, so that the user experience is poor.
In automatic control of an air conditioning outlet on an existing vehicle, temperatures inside and outside the vehicle, an air volume of the air blower, or a temperature of the face and the clothes of a passenger are taken into consideration, a difference between people is not taken into consideration, that is, actual requirements of different passengers are not taken into consideration, so that the user experience is poor.

Herein, the present invention will be described in detail with reference to the drawings.
The embodiments of the present invention provide a method for controlling an air conditioning outlet of a vehicle, and in some embodiments, the method for controlling an air conditioning outlet of a vehicle includes:
According to the present invention, controlling the air conditioning outlet of the vehicle not only considers environmental factors but also considers requirements of a user (the user can set a temperature meeting his/her own requirements), and a more matched working mode can be automatically provided based on the requirements of the user, so that the matching degree is higher, it does not require the user to manually adjust the air outlet direction, and an temperature inside the vehicle can always meet the requirements of the user.
In the embodiment of the present invention, the air conditioning outlet may include an opening provided in an instrument panel or an interior trim panel, a shutter arranged in the opening, and a motor driving the shutter to rotate to adjust the air outlet direction. In addition, an execution main body of the control method may be a control unit (for example, an electronic control unit (ECU)) of an air conditioner, and a control mode of the air conditioning outlet may include the following several types: an operation mode, a forced centralization mode, a forced indirect mode, an automatic mode (Auto mode), and a switching mode.
The operation mode refers to that the user can slide up, down, left, right within a specified area on a control mode operation interface of the air conditioning outlet to adjust an air direction. In this mode, the air conditioning outlet can be freely adjusted.
The forced centralization mode refers to a mode in which the air conditioning outlet is forced to execute centralized blowing in a fixed manner, and the user may click an icon ICON of the forced centralization mode on the control mode operation interface of an electric air outlet, thereby adjusting the air outlet direction of the air conditioning outlet to blow air in a centralized manner (blowing air toward the face of the user all the time, or blowing air toward the hand and the body of the user all the time, for example, air may be blown toward the hand of the user sitting on the driver seat, and air may be blown toward the body of the user sitting on the passenger seat). In this mode, a plurality of air conditioning outlets can be simultaneously controlled to execute centralized blowing without an operation on each air conditioning outlet, thereby shortening the operation time.
The forced indirect mode refers to a mode in which the air conditioning outlet is forced to execute indirect blowing in a fixed manner, and the user can click the icon ICON of the forced indirect mode on the control mode operation interface of the air conditioning outlet, thereby adjusting the air outlet direction of the air conditioning outlet to be indirect blowing, so that air is blown avoiding the face of the user, and may be blown upward and toward the top of the head of the user. Also, air may be blown downward and toward the foot of the user. In this mode, a plurality of air conditioning outlets can be simultaneously controlled to execute indirect blowing without an operation on each air conditioning outlet, thereby shortening the operation time.
The automatic mode refers to a working mode in which the control unit automatically adjusts the air conditioning outlet based on collected information. The automatic mode is started by clicking an automatic mode icon ICON on the control mode operation interface of the air conditioning outlet.
The switching mode refers to a mode in which an icon ICON of a switch is clicked on the control mode operation interface of the air conditioning outlet, thereby achieving opening and closing of the air conditioning outlet.
The forced centralization mode, the forced indirect mode, the automatic mode, and the switching mode may also be manipulated by voice or gesture recognition.
In the embodiment of the present invention, the present invention implements control of the air conditioning outlet of the vehicle in an automatic mode, and
In step S1, an ambient temperature and a user set temperature are collected. The ambient temperature refers to a temperature outside the vehicle and a temperature inside the vehicle, and the temperature outside the vehicle and the temperature inside the vehicle may be acquired by a temperature sensor in the vehicle and then transmitted to the ECU of the air conditioner. The temperatures can also be acquired by other temperature measuring devices and then transmitted to the ECU of the air conditioner.
The temperature outside the vehicle is acquired by an outside temperature sensor, the outside temperature sensor is generally made of a thermistor, and a resistance thereof changes when the temperature outside the vehicle changes. When the temperature is low, the resistance is large, and when the temperature is high, the resistance is small.
The temperature inside the vehicle is acquired by an in-vehicle sensor, and the in-vehicle sensor similarly adopts a thermistor material, and has a negative temperature coefficient. The sensor is generally installed below an instrument board and connected to an air conditioning duct through an air tube, and when an airflow passes rapidly, the generated vacuum guides air through the in-vehicle sensor.
The user set temperature is set by the user according to his/her own requirements. The larger a difference between the user set temperature and the ambient temperature, the larger an air conditioning load.
In step S2, a target value is determined according to the ambient temperature and the user set temperature. The target value refers to a temperature air output (TAO) value, and the TAO value refers to an effective air-out temperature, and is an air temperature of an air blower necessary to maintain the temperature inside the vehicle at a set temperature. The TAO value is a default value of the air conditioner and is a control index of a temperature in a carriage. Generally, according to the TAO value, an air blowing temperature, an air-in mode (inner circulation and outer circulation), and an air supply mode (blowing air to face, blowing air to foot, and the like) of the air conditioner can be controlled. In the present invention, the TAO value is calculated according to the temperatures inside and outside the vehicle, and the user set temperature. The TAO value may be calculated according to parameters such as the user set temperature, the temperature inside the vehicle, and the temperature outside the vehicle, or may be calculated by adding insolation to these parameters. Hereinafter, an example of a calculation method of the TAO value is given.
Here, KSET, KR, KAM, and KS are coefficients, and C is a constant, these parameters may be appropriately set by those having ordinary skills in the art in consideration of actual situations and the like. In addition, TSET is a set temperature, TR is a temperature inside the vehicle, TAM is a temperature outside the vehicle, and TS is insolation.
In step S3, a target working mode is determined from a plurality of preset working modes of an air conditioning outlet according to the target value, the working mode including a preset air outlet direction. In the embodiment of the present invention, the target working mode can be determined from the plurality of preset working modes of the air conditioning outlet according to the TAO value.
In step S4, the air conditioning outlet is enabled to work in the target working mode. After the TAO value is determined, the target working mode of the air conditioning outlet may be determined based on the TAO value.
In some embodiments, the working mode includes a first working mode and a second working mode, the first working mode including a preset first air outlet direction in which the air conditioning outlet faces the user, and the second working mode including a preset second air outlet direction in which the air conditioning outlet does not face the user.
In some embodiments, the working mode further includes a third working mode, the third working mode including a preset third air outlet direction in which the air conditioning outlet intermittently faces the user.
In the present invention, according to a change of the target value, different working modes can be achieved, so that the operation frequency of the user on air direction adjustment is reduced, and the expectation of most users can be met.
In some embodiments, the first working mode is a centralized blowing mode, the second working mode is an indirect blowing mode, and the third working mode is a left-right sweeping mode.
In the embodiments of the present invention, the first working mode may be a centralized blowing mode, and the centralized blowing mode is that the air conditioning outlet faces the user and may blow air toward the face of the user. The second working mode may be an indirect blowing mode, and the indirect blowing mode is that the air conditioning outlet avoids the user, in which air may be blown avoiding the face of the user, and may be blown upward and toward the top of the head of the user. Also, air may be blown downward and toward the foot of the user. The third working mode may be a left-right sweeping mode, and the left-right sweeping mode is that the air conditioning outlet intermittently faces the user, in which the air outlet direction continuously changes, that is, the air conditioning outlet faces the user and the left-right sweeping mode is adopted to blow air, specifically, the air outlet direction of the air conditioning outlet is blowing air from left to right (left and right in a vehicle-width direction), and then blowing air from right to left, thereby achieving left-right sweeping in a reciprocating manner.
In some embodiments of the present invention, the first working mode may include a preset first air outlet direction and a preset third air outlet direction, and the first air outlet direction is that the air conditioning outlet faces the user, that is, centralized blowing, in which air may be blown centralizedly toward the face of the user, or may be blown centralizedly toward the body of the user, or may be blown centralizedly toward the hand of the user. The third air outlet direction is that the air conditioning outlet intermittently faces the user, that is, left-right sweeping, in which air may be intermittently blown toward the face of the user. The first working mode may be controlled to be the following air blowing modes, for example: first execute the centralized blowing, and then the left-right sweeping; alternatively, execute the centralized blowing and the left-right sweeping in cycles, that is, execute the centralized blowing for a preset time (for example, 30 seconds)→execute the left-right sweeping for 30 seconds→execute the centralized blowing for 30 seconds→execute the left-right sweeping for 30 seconds . . . until entering the second working mode. Similarly, the second working mode may include a preset second air outlet direction and a preset third air outlet direction, and the second air outlet direction is that the air conditioning outlet avoids the user, that is, indirect blowing, in which air may be blown toward the top of the head of the user, or may be blown toward the foot of the user. The third air outlet direction is that the air conditioning outlet intermittently faces the user, that is, left-right sweeping, in which air may be intermittently blown toward the face of the user. The second working mode may be controlled to be the following air blowing modes, for example: first execute the left-right sweeping, and then the indirect blowing; alternatively, execute the left-right sweeping and the indirect blowing in cycles. Similarly, the third working mode may also include a preset first air outlet direction and a preset third air outlet direction, and the first air outlet direction is that the air conditioning outlet faces the user, that is, centralized blowing, in which air may be blown centralizedly toward the face of the user. The third air outlet direction is that the air conditioning outlet intermittently faces the user, that is, left-right sweeping, in which air may be intermittently blown toward the face of the user. The third working mode may be controlled to be the following air blowing modes, for example: first execute the left-right sweeping, and then the centralized blowing; alternatively, execute the left-right sweeping and the centralized blowing in cycles, that is, execute the left-right sweeping for a preset time (for example, 30 seconds)→execute the centralized blowing for 30 seconds→execute the left-right sweeping for 30 seconds→execute the centralized blowing for 30 seconds . . . until entering the second working mode.
The first working mode, the second working mode, and the third working mode may also include three or more preset air outlet directions.
Each working mode of the present invention is provided with a corresponding air blowing mode, so that different requirements of users can be met.

In the present invention, although the target value changes all the time, when the target value changes within a certain value range, the working mode of the air conditioning outlet does not change (that is, the working mode is fixed within a range of value), so that the user can feel temperature falling in a short time, thereby improving the user experience.

Each coordinate point for the driver seat in the centralized blowing mode, the left-right sweeping mode, and the indirect blowing mode may be set as follows. Centralized blowing mode: in the direction H on a rear side of the vehicle that the air conditioning outlet faces, the air conditioning outlet of the driver seat may be set to face the coordinate point 6; and in the direction B on a rear side of the vehicle that the air conditioning outlet faces, the first air conditioning outlet of the driver seat may be set to face the coordinate point 10, and the second air conditioning outlet of the driver seat may be set to face the coordinate point 4. The coordinate points in this mode are the third coordinate points, and for the direction H: the third coordinate points are set as the coordinate point 6 shown in
Left-right sweeping mode: in the direction H on a rear side of the vehicle that the air conditioning outlet faces, the air conditioning outlet of the driver seat may be set to face the coordinate point 6; and in the direction B on a rear side of the vehicle that the air conditioning outlet faces, the first air conditioning outlet of the driver seat can be set to execute the left-right sweeping facing the coordinate points 4 to 12, and the second air conditioning outlet of the driver seat can be set to execute the left-right sweeping facing the coordinate points 4 to 12, specifically, the air conditioning outlet gradually moves to blow air from toward the coordinate point 4 to toward the coordinate point 12, and then gradually moves to blow air from toward the coordinate point 12 to toward the coordinate point 4, thereby achieving the left-right sweeping in a reciprocating manner. The coordinate points in this mode are the first coordinate point and the second coordinate point, and for the direction H: both the first coordinate point and the second coordinate point are set as the coordinate point 6 shown in
Indirect blowing mode: in the direction H on a rear side of the vehicle that the air conditioning outlet faces, the air conditioning outlet of the driver seat may be set to face the coordinate point 12; and in the direction B on a rear side of the vehicle that the air conditioning outlet faces, the first air conditioning outlet of the driver seat may be set to face the coordinate point 2, and the second air conditioning outlet of the driver seat may be set to face the coordinate point 12. The coordinate points in this mode are the fourth coordinate points, and for the direction H: the fourth coordinate points are set as the coordinate point 12 shown in
The specific coordinate points of each mode in the heating state may all be set by the user. Each coordinate point of the centralized blowing mode and the indirect blowing mode (including the first indirect blowing mode and the second indirect blowing mode) is set as follows.
First indirect blowing mode: in the direction H on a rear side of the vehicle that the air conditioning outlet faces, the air conditioning outlet of the driver seat may be set to face the coordinate point 12; and in the direction B on a rear side of the vehicle that the air conditioning outlet faces, the first air conditioning outlet of the driver seat may be set to face the coordinate point 2, and the second air conditioning outlet of the driver seat may be set to face the coordinate point 12. The coordinate points in this mode are the fourth coordinate points, and for the direction H: the fourth coordinate points are both set as the coordinate point 12 shown in
Centralized blowing mode: in the direction H on a rear side of the vehicle that the air conditioning outlet faces, the air conditioning outlet of the driver seat may be set to face the coordinate point 3; and in the direction B on a rear side of the vehicle that the air conditioning outlet faces, the first air conditioning outlet of the driver seat may be set to face the coordinate point 9, and the second air conditioning outlet of the driver seat may be set to face the coordinate point 5. The coordinate points in this mode are the third coordinate points, and for the direction H: the third coordinate points are set as the coordinate point 3 shown in
Second indirect blowing mode: in the direction H on a rear side of the vehicle that the air conditioning outlet faces, the air conditioning outlet of the driver seat may be set to face the coordinate point 0; and in the direction B on a rear side of the vehicle that the air conditioning outlet faces, the first air conditioning outlet of the driver seat may be set to face the coordinate point 2, and the second air conditioning outlet of the driver seat may be set to face the coordinate point 12. The coordinate points in this mode are the fourth coordinate points, and for the direction H: the fourth coordinate points are both set as the coordinate point 0 shown in
The specific coordinate points of the passenger seat may be set to be the same as or different from the specific coordinate points of the driver seat.
The specific coordinate points of the first indirect blowing mode in the heating state may be consistent with the indirect blowing mode in the cooling state, and the specific coordinate points of the centralized blowing mode and the second indirect blowing mode may be set by the user (same for the driver seat and the passenger seat).
The specific coordinate point in each working mode of the air conditioning outlet of the passenger seat generally maintains the specific coordinate point set in the previous working mode, but can also be reset by the user, and after the user resets the specific coordinate point, the air conditioning outlet is controlled to blow air according to the specific coordinate point in each working mode set by the user.
In some embodiments, the method further includes:
recording a specific coordinate point set by the user and the working mode of the air conditioning outlet; and controlling, when the user is detected, the air conditioning outlet to blow air toward the specific coordinate point in the working mode according to the recorded specific coordinate point and working mode set by the user.
In the present invention, the user can adjust the air conditioning outlet to face a specific coordinate point in a fixed working mode of the air conditioning outlet, and the working mode and the specific coordinate point can both be recorded, when the same user logs in a next ride, after the user selects a working mode, the air conditioning outlet can be controlled to blow air toward the user at the specific coordinate point in each working mode set last time.
In the embodiments of the present invention, an electronic control unit (ECU) of the air conditioner may record specific coordinate point information of different users, and in a case of the same user and the same working mode, a system may extract a working mode recorded last time by the user, and control the air conditioning outlet to blow air according to the working mode. The working mode includes the specific coordinate point information recorded by the user.
Specifically, the ECU may determine whether it is the same user in the following manner. After a user sits in the vehicle and completes seat position adjustment, a camera starts to identify the user, and logs in to a user account after identification. Alternatively, it may be the user inputting the user account on the control mode operation interface. Further, it may be the user using a mobile terminal to scan a two-dimensional code for login displayed on the control mode operation interface, and then the ECU acquiring the user account and identifying the user identity. Specifically, the mobile terminal may be a mobile phone, a tablet personal computer, or the like.
Extracting a working mode recorded last time by the user, and controlling the air conditioning outlet to blow air according to the working mode is specifically as follows: in a case where the direction of the air conditioning outlet is controlled to be centralized blowing, when the user sets the air conditioning outlet to blow air toward the third coordinate point, the ECU of the air conditioner may record a habit of the user, and centralized modes thereafter will all be executed toward the third coordinate point; in a case where the direction of the air conditioning outlet is controlled to be indirect blowing, when the user sets the air conditioning outlet to blow out air toward the fourth coordinate point, the ECU of the air conditioner may record a habit of the user, and indirect modes thereafter will all be executed toward the fourth coordinate point; and in a case where the direction of the air conditioning outlet is controlled to be left-right sweeping, when the user sets the orientation of the air conditioning outlet to be between the first coordinate point and the second coordinate point, the ECU of the air conditioner may record a habit of the user, and left-right sweeping modes thereafter will all be sweeping air back and forth between the first coordinate point and the second coordinate point.
In some embodiments, the present invention may further include: adjusting, when an opened air outlet channel is VENT (blow air to people) or B/L (blow air to people+blow air to foot), the working mode of the air conditioning outlet according to the TAO value.
In some embodiments, the present invention may further include: adjusting, when the opened air outlet channel is HEAT (blow air to foot), H/D (blow air to foot+blow air to window), or DEF (blow air to window), the air conditioning outlet to the indirect blowing mode, in which air is blown upward, specifically air is blown toward the top of the head of the user.
A first embodiment of the present invention provides a method for controlling an air conditioning outlet of a vehicle, the method including: acquiring a temperature inside the vehicle, a temperature outside the vehicle, and a user set temperature (S1), calculating a TAO value according to the temperature inside the vehicle, the temperature outside the vehicle, and the user set temperature (S2), determining a target working mode from two working modes (centralized blowing mode and indirect blowing mode) of an air conditioning outlet according to the TAO value (S3), and enabling the air conditioning outlet to work in the target working mode (S4).
A relation between the TAO value and the working mode of the air conditioning outlet is shown in Table 2.
As shown in
In the heating state, when the calculated TAO value is within the fourth value range, the air conditioning outlet is controlled to be in the indirect blowing mode. When the calculated TAO value is within the fifth value range, the air conditioning outlet is controlled to be in the centralized blowing mode. When the ambient temperature increases, the TAO value decreases and changes from the fifth value range toward the fourth value range, and when the TAO value changes to the fourth value range, the air conditioning outlet is controlled to change from the centralized blowing mode to the indirect blowing mode. When the user set temperature increases, the TAO value increases and changes from the fourth value range toward the fifth value range, and when the TAO value changes to the fifth value range, the air conditioning outlet is controlled to change from the indirect blowing mode to the centralized blowing mode.
A second embodiment of the present invention provides a method for controlling an air conditioning outlet of a vehicle, the method including: acquiring a temperature inside the vehicle, a temperature outside the vehicle, and a user set temperature (S1), calculating a TAO value according to the temperature inside the vehicle, the temperature outside the vehicle, and the user set temperature (S2), determining a target working mode from three working modes (centralized blowing mode, indirect blowing mode, and left-right sweeping mode) of an air conditioning outlet according to the TAO value (S3), and enabling the air conditioning outlet to work in the target working mode (S4).
A relation between the TAO value and the working mode of the air conditioning outlet is shown in Table 3.
As shown in
In the heating state, when the calculated TAO value is within the fourth value range, the air conditioning outlet is controlled to be in the indirect blowing mode. When the calculated TAO value is within the fifth value range, the air conditioning outlet is controlled to be in the centralized blowing mode. When the ambient temperature increases, the TAO value decreases and changes from the fifth value range toward the fourth value range, and when the TAO value changes to the fourth value range, the air conditioning outlet is controlled to change from the centralized blowing mode to the indirect blowing mode. When the user set temperature increases, the TAO value increases and changes from the fourth value range toward the fifth value range, and when the TAO value changes to the fifth value range, the air conditioning outlet is controlled to change from the indirect blowing mode to the centralized blowing mode.
