[0002] As an indispensable part of a car, car air conditioners can provide people with a more comfortable temperature environment. Car air conditioners have multiple air outlets to achieve uniform air supply to every corner of the car from different locations.

The sudden change in air output causes changes in wind speed, which may make users near other air outlets feel uncomfortable. Summary of the Invention

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0026] In the various embodiments of the present application, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0027] In the prior art, vehicle air conditioners have multiple air outlets to achieve uniform air supply from different locations to every corner of the vehicle. At the same time, passengers in different positions can independently adjust the wind direction and air volume of nearby air outlets according to their needs. Since the total air output of each air outlet is determined by the speed of the vehicle air conditioner's blower, if the air output of one air outlet is changed due to the user adjusting the blades, for mechanical air outlets, that is, vehicle air conditioners whose blower speed cannot be automatically adjusted according to the air output conditions, it is inevitable that the air output of other air outlets will be affected. The change in wind speed caused by the sudden change in air output may make users near other air outlets feel uncomfortable.

[0028] In view of this, the present application provides a vehicle air conditioning control method, device, electronic device and vehicle. The present application can obtain the target air volume corresponding to the target air outlet when the blade opening is the second opening and the initial air volume corresponding to each remaining air outlet when the blade opening of the target air outlet is the first opening when the blade opening of the target air outlet is adjusted from the first opening to the second opening, thereby obtaining the target total air volume and the target air volume distribution ratio, and then adjusting the working voltage of the blower and the damper opening corresponding to at least one air outlet. When the blade opening of the target air outlet changes, the air volume of the target air outlet can meet the user's adjustment purpose, while other air outlets can be unaffected by the change in the air volume of the target air outlet and maintain the initial air volume, thereby not changing the air outlet speed of other air outlets.

[0029] like Figure 1 As shown, an embodiment of the present application provides a vehicle air conditioning control method, the method comprising:

[0030] Step 101. When the blade opening of the target air outlet is adjusted from a first opening to a second opening, obtain the target air volume corresponding to the target air outlet when the blade opening is the second opening; wherein, the vehicle air conditioner includes multiple air outlets, and the target air outlet is at least one of the multiple air outlets.

[0031] The vehicle air conditioning control method provided in the embodiments of the present application is applied to an air conditioning controller, wherein the vehicle air conditioning controller includes multiple air outlets. Each air outlet is provided with blades with adjustable openings. The user can manually adjust the opening of the blades to adjust the outlet area, thereby adjusting the air volume. When the blades are fully open, the outlet has the largest ventilation area and the largest air volume. As the blades gradually close, the ventilation area decreases, and the air volume also decreases accordingly.

[0032] When the vehicle air conditioner is turned on, the air conditioner controller can monitor the size of the blade opening at each air outlet and whether it changes.

[0033] When a change in the blade opening of an air outlet is detected, the air outlet is determined as a target air outlet, and the blade opening of the target air outlet before the change is determined as a first opening, and the blade opening after the change is determined as a second opening. The second opening can be greater than or less than the first opening. The target air outlet can be at least one of multiple air outlets included in the vehicle air conditioner.

[0034] At this time, the target air volume corresponding to the target air outlet when the blade opening is the second opening is obtained. Since the user stops adjusting the blade opening of the air outlet when the air volume at the air outlet reaches the desired air volume, the target air volume obtained at this time is the desired air volume when the user adjusts the blade opening of the air outlet.

[0035] Step 102 : For each remaining air outlet except the target air outlet among the plurality of air outlets, obtain an initial air volume corresponding to the remaining air outlet when the blade opening of the target air outlet is a first opening.

[0036] Since the total amount of air output from each air outlet is determined by the speed of the car air conditioner's blower, when the air output from one of the air outlets is changed due to the user adjusting the blades, the mechanical air outlet, that is, the air outlet of the car air conditioner whose blower speed cannot be automatically adjusted according to the air output conditions, will inevitably affect the air output of other air outlets. The change in wind speed caused by the sudden change in air output may make users near other air outlets feel uncomfortable.

[0037] During the specific implementation process, the air conditioning controller also obtains the initial air volume corresponding to each of the remaining air outlets other than the target air outlet among the multiple air outlets included in the vehicle air conditioner when the blade opening of the target air outlet is a first opening, when detecting a change in the blade opening of the target air outlet. That is, the initial air volume corresponding to each of the remaining air outlets before the blade opening of the target air outlet is adjusted. For example, the vehicle air conditioner includes four air outlets, namely the first air outlet, the second air outlet, the third air outlet, and the fourth air outlet. When the blade opening of the first air outlet changes, the air volume of the first air outlet after the blade opening changes, that is, the target air volume, is obtained through step 101. The air volume of the second air outlet, the third air outlet, and the fourth air outlet before the blade opening of the first air outlet changes, that is, the initial air volume corresponding to each air outlet, is obtained through step 102.

[0038] Step 103 : Determine the target total air volume and the target air volume distribution ratios corresponding to the multiple air outlets based on the target air volume and the initial air volumes corresponding to the remaining air outlets.

[0039] After obtaining the target air volume and the initial air volumes corresponding to each remaining air outlet, the target total air volume can be obtained. Specifically, the target total air volume is equal to the sum of the target air volume and the initial air volumes corresponding to each remaining air outlet. The target air volume distribution ratio corresponding to the multiple air outlets included in the vehicle air conditioner can also be obtained, that is, the ratio of the target air volume to the initial air volumes corresponding to each remaining air outlet.

[0040] Step 104: Adjust the operating voltage corresponding to the blower of the vehicle air conditioner according to the target total air volume; and adjust the damper opening corresponding to at least one of the multiple air outlets according to the target air volume distribution ratio.

[0041] Specifically, the blower's operating voltage directly affects the blower's speed, which in turn affects the air volume generated by the blower. The air volume generated by the blower passes through various dampers into the air duct corresponding to each air outlet, and further enters the passenger compartment through the blades of the air outlet. The blades are the air guide blades at the air outlet, and the dampers are the dampers in the air conditioning duct used to adjust the air volume. The opening of both the blades and the dampers are adjustable. The user in the passenger compartment can adjust the air volume of the air outlet by adjusting the opening of the air outlet blades. The air conditioning controller can adjust the opening of the dampers of each air outlet to change the distribution ratio of the air volume generated by the blower among the air outlets.

[0042] It should be noted that when the airflow at the target outlet changes, if the blower speed remains unchanged, the airflow at the remaining outlets (excluding the target outlet) will also change accordingly, thereby changing the airflow speed at each of the remaining outlets. For example, if the blade opening of the target outlet decreases, the airflow at the target outlet will decrease. Then, if the total airflow generated by the blower remains unchanged, the airflow at each of the remaining outlets will increase, and accordingly, the airflow speed will also increase.

[0043] It should be further explained that when the blower speed is changed to make the total air volume generated by the blower equal to the target total air volume, if the target total air volume is still distributed according to the original air volume distribution ratio, the air volume of each air outlet will be affected. That is, the air volume of the target air outlet will not be the target air volume, and may exceed or fall short of the target air volume, and the air volume of each remaining air outlet will not be the initial air volume. For example, the vehicle air conditioner includes four air outlets, namely the first air outlet, the second air outlet, the third air outlet, and the fourth air outlet. When the original air volume distribution ratio of the four air outlets is 1:1:1:1 and the total air volume is 400m3 / h, the air volume distributed to each air outlet is 100m3 / h. At this time, if the blade opening of the first air outlet is reduced by half, the target air volume of the first air outlet is 50m3 / h. At this time, the target total air volume is 350m3 / h, and the target air volume distribution ratio becomes 0.5:1:1:1. When the air volume generated by the blower is adjusted to the target total air volume, the air door opening of the air outlet also needs to be changed accordingly so that the target total air volume is distributed among the air outlets according to the target air volume distribution ratio. When adjusting the damper opening of the air outlet, it is necessary to adjust it in combination with the current damper opening of each air outlet and the target air volume distribution ratio. In this example, only the damper opening corresponding to the target air outlet can be adjusted. By reducing the damper opening of the target air outlet by half, the target total air volume can be distributed among the air outlets at the target air volume distribution ratio of 0.5:1:1:1. In addition, if the blade opening of the first air outlet is doubled, the target air volume of the first air outlet is 200m3 / h. At this time, the target total air volume is 500m3 / h, and the target air volume distribution ratio becomes 2:1:1:1. When adjusting the air volume generated by the blower to the target total air volume, the damper opening of the air outlet also needs to be changed accordingly so that the target total air volume is distributed among the air outlets at the target air volume distribution ratio. When adjusting the damper opening of the air outlet, it is necessary to adjust it in combination with the current damper opening of each air outlet and the target air volume distribution ratio. In this example, if the damper opening of the first air outlet is already the maximum at this time and the damper opening cannot be further increased, the damper openings of the remaining air outlets can be reduced by half to achieve the target total air volume and distribute it among the air outlets according to the target air volume distribution ratio.

[0044] Therefore, when the air conditioning controller obtains the target total air volume, it adjusts the blower's operating voltage based on the target total air volume so that the blower generates the target total air volume. Simultaneously, when the target air volume distribution ratio is obtained, the air damper opening corresponding to at least one of the multiple air outlets is adjusted based on the target air volume distribution ratio so that the air volume of each air outlet meets the target air volume distribution ratio. This results in the target air volume being the target air volume, while the air volumes of the remaining air outlets are the corresponding initial air volumes.

[0045] In an embodiment of the present application, when the blade opening of the target air outlet is adjusted from a first opening to a second opening, the target air volume corresponding to the target air outlet when the blade opening is the second opening and the initial air volume corresponding to each remaining air outlet when the blade opening of the target air outlet is the first opening are obtained, thereby obtaining the target total air volume and the target air volume distribution ratio, and then adjusting the working voltage of the blower and the damper opening corresponding to at least one air outlet. When the blade opening of the target air outlet changes, the air volume of the target air outlet can meet the user's adjustment purpose, and at the same time, other air outlets can be unaffected by the change in the air volume of the target air outlet, maintain the initial air volume, and thus will not change the air outlet speed of other air outlets.

[0046] In an optional embodiment of the present application, a blade opening detector is provided at each of the air outlets; the method further includes:

[0047] When the vehicle air conditioner is in an on-state, for each of the air outlets, obtaining the blade opening of the air outlet based on a blade opening detector corresponding to the air outlet;

[0048] The air outlet at which the blade opening changes is determined as the target air outlet, the blade opening before the change is determined as the first opening, and the blade opening after the change is determined as the second opening.

[0049] Specifically, when the vehicle air conditioner is turned on, the air conditioner controller monitors the blade opening of each air outlet included in the vehicle air conditioner. When a change in the blade opening of an air outlet is detected, the air outlet is determined as the target air outlet, and the blade opening before the change is determined as a first opening, and the blade opening after the change is determined as a second opening.

[0050] In a specific implementation process, a blade opening detector is provided at each air outlet of the vehicle air conditioner, and the air conditioner controller obtains the blade opening of the air outlet based on the blade opening detector.

[0051] The above-mentioned implementation scheme of the present application obtains the blade opening of each air outlet based on each blade opening detector, so as to determine the target air outlet where the blade opening has changed, and the second opening of the target air outlet after the blade is adjusted, so as to facilitate the subsequent determination of the target air volume at the target air outlet based on the second opening.

[0052] The following describes how to obtain the blade opening of the air outlet. In an optional embodiment of the present application, the air outlet is provided with a switch assembly for adjusting the blade opening, and the blade opening detector includes an elastic assembly and a pressure sensor for detecting the elastic force corresponding to the elastic assembly; the elastic assembly is connected to the switch assembly, and the pressure sensor is provided between the elastic assembly and the switch assembly. When the switch assembly moves in a direction to increase the blade opening, the switch assembly compresses the elastic assembly.

[0053] Acquiring the blade opening of the air outlet based on a blade opening detector corresponding to the air outlet includes:

[0054] Obtaining a pressure value collected by the pressure sensor;

[0055] The blade opening is determined according to a pre-calibrated correspondence between the pressure value and the blade opening and the pressure value.

[0056] Specifically, the blade opening detector includes an elastic component, which can be a spring, and a pressure sensor for detecting the elastic force corresponding to the elastic component. A switch assembly for adjusting the blade opening is provided at the air outlet. This switch can be a sliding switch or a knob switch. The elastic component is connected to the switch assembly, and the pressure sensor is positioned between the elastic component and the switch assembly. When the switch assembly moves in the direction of increasing the blade opening, the switch assembly compresses the elastic component; the greater the degree of compression, the greater the elastic force detected by the pressure sensor.

[0057] For example, Figure 2 As shown, when the switch assembly is a sliding switch, the switch assembly specifically includes a slider 201, a housing 202, and a sliding groove 203. One end of the slider 201 is connected to the vanes of the air outlet, and the other end is a protrusion for the user to push. The housing 202 is provided with a groove 204 that matches the protrusion. When the protrusion of the slider 201 is pushed along the groove 204 in a first direction, the slider 201 slides within the sliding groove 203, causing the vanes to open. When the protrusion reaches the limit point of the groove 205, the vanes are fully opened. A spring 205 is located within the sliding groove 203, and a pressure sensor 206 is disposed between the spring 205 and the slider 201. When the slider 201 slides in the first direction, the spring 205 is compressed. The pressure sensor 206 receives the elastic force of the spring 205 and transmits the collected pressure signal to the air conditioning controller.

[0058] When obtaining the vane opening of the air outlet based on the vane opening detector, the air conditioning control can obtain a pressure signal fed back by the pressure sensor and obtain a pressure value collected by the pressure sensor based on the pressure signal. Specifically, a correspondence between the pressure value and the vane opening can be pre-calibrated, so that the vane opening of the air outlet can be determined based on the correspondence and the pressure value.

[0059] The above-mentioned implementation scheme of the present application obtains the pressure value collected by the pressure sensor, and determines the blade opening based on the correspondence between the pre-calibrated pressure value and the blade opening and the pressure value, so that when the user adjusts the blade opening of the air outlet, the blade opening of the air outlet can be determined in time through the pressure change and the pressure value.

[0060] In an optional embodiment of the present application, a wind speed sensor is provided at each of the air outlets;

[0061] Obtaining a target air volume corresponding to the target air outlet when the blade opening is the second opening includes:

[0062] obtaining a target wind speed collected by a wind speed sensor corresponding to the target air outlet when the blade opening of the target air outlet is the second opening;

[0063] determining a target air outlet area corresponding to the target air outlet according to the second opening;

[0064] The target air volume is determined according to the target wind speed and the target air outlet area.

[0065] In the embodiment of the present application, a wind speed sensor is provided at each air outlet. Each wind speed sensor is connected to an air conditioning controller, and the air conditioning controller can obtain the wind speed of each air outlet through each wind speed sensor.

[0066] Specifically, when obtaining the target air volume, based on the air volume calculation method, the air volume is equal to the product of the air velocity and the air area. Therefore, it is necessary to determine the target wind speed and target air area corresponding to the target air outlet. The target wind speed of the target air outlet when the blade opening is at a second opening can be obtained using the wind speed sensor corresponding to the target air outlet. Simultaneously, the target air area of ​​the target air outlet can be determined based on the second opening. A larger blade opening results in a larger air area.

[0067] After obtaining the target wind speed and target air outlet area, the target air volume at the target air outlet can be determined.

[0068] The above implementation scheme of the present application determines the target air volume through the target air outlet area and the target wind speed, so that the desired air volume of the user adjusting the blade opening can be determined, and then the target total air volume and the target air volume distribution ratio can be determined based on the target air volume.

[0069] In an optional embodiment of the present application, obtaining the initial air volume of the remaining air outlet corresponding to when the blade opening of the target air outlet is the first opening includes:

[0070] Obtaining initial blade openings and initial wind speeds corresponding to the remaining air outlets when the blade openings of the target air outlets are the first openings;

[0071] Determining the initial air outlet areas corresponding to the remaining air outlets according to the initial blade openings;

[0072] The initial air volume is determined according to the initial wind speed and the initial air outlet area.

[0073] Specifically, when obtaining the initial air volume, based on the air volume calculation method, the air volume is equal to the product of the air velocity and the air area. Therefore, it is necessary to determine the initial wind velocity and initial air area corresponding to each remaining air outlet. The initial wind velocity of each remaining air outlet when the blade opening of the target air outlet is the first opening can be obtained using the wind speed sensors corresponding to the remaining air outlets. At the same time, the initial air area of ​​the remaining air outlets can be determined based on the initial blade openings corresponding to the remaining air outlets.

[0074] For each remaining air outlet, after obtaining the initial wind speed and initial air outlet area of ​​the remaining air outlet, the initial air volume of the remaining air outlet can be determined.

[0075] The above implementation scheme of the present application determines the initial air volume through the initial air outlet area and the initial wind speed, so that the initial air volume of each remaining air outlet can be determined before the user adjusts the blade opening of the target air outlet, and then the target total air volume and the target air volume distribution ratio can be determined based on the initial air volume.

[0076] In an optional embodiment of the present application, adjusting the operating voltage corresponding to the blower of the vehicle air conditioner according to the target total air volume includes:

[0077] Obtain the corresponding relationship between air volume and blower voltage;

[0078] determining a target voltage corresponding to the blower according to the corresponding relationship and the target total air volume;

[0079] The operating voltage of the blower is adjusted to the target voltage.

[0080] There's a certain relationship between the air volume and the blower's operating voltage for a vehicle air conditioner. This relationship can be pre-calibrated. When determining the target total air volume, this relationship can be used to determine the target blower voltage. By adjusting the blower's operating voltage to the target voltage, the blower can achieve the target air volume.

[0081] The above-mentioned implementation scheme of the present application obtains the correspondence between the air volume and the blower voltage, and based on the correspondence and the target total air volume, determines the operating voltage of the blower when it produces the target total air volume, that is, the target voltage, thereby realizing automatic adjustment of the blower operating voltage when the blade opening of the air outlet changes. When the blade opening of the target air outlet changes, the air volume of the target air outlet can meet the user's adjustment purpose, while other air outlets can be unaffected by the change in the air volume of the target air outlet, maintain the initial air volume, and thus will not change the air outlet speed of other air outlets.

[0082] In an optional embodiment of the present application, adjusting the damper opening corresponding to at least one of the plurality of air outlets according to the target air volume distribution ratio includes:

[0083] determining, according to the target air volume distribution ratio, the opening ratios of the plurality of dampers corresponding to the plurality of air outlets;

[0084] Determining the air outlet to be adjusted and the target air outlet opening corresponding to the air outlet to be adjusted according to the opening ratio and the current air door opening corresponding to each air outlet;

[0085] The damper opening of the air outlet to be adjusted is adjusted to the target damper opening.

[0086] The air volume generated by the blower enters the air duct corresponding to each air outlet through each air door, and further enters the passenger compartment through the blades of the air outlet.

[0087] During specific implementation, when the blower speed is changed so that the total air volume generated by the blower equals the target total air volume, if the target total air volume is still distributed according to the original air volume distribution ratio, the air volume of each air outlet will be affected. That is, the air volume of the target air outlet is not the target air volume, and may exceed or fail to reach the target air volume, and the air volume of each remaining air outlet may also exceed or fail to reach the initial air volume. After adjusting the air volume generated by the blower to the target total air volume by adjusting the operating voltage of the blower, it is also necessary to change the damper opening of at least one air outlet to achieve the distribution of the target total air volume among the air outlets according to the target air volume distribution ratio.

[0088] Specifically, when adjusting the damper opening corresponding to at least one of the multiple air outlets, the opening ratio of the multiple dampers corresponding to the multiple air outlets can be determined based on the target air volume distribution ratio, and then the air outlet to be adjusted and the target damper opening corresponding to the air outlet to be adjusted can be determined based on the opening ratio and the current damper opening corresponding to each air outlet. The air outlet to be adjusted here can be one or more, and finally the damper opening of the air outlet to be adjusted is adjusted to the target damper opening.

[0089] Exemplarily, the vehicle air conditioner includes four air outlets, namely a first air outlet, a second air outlet, a third air outlet and a fourth air outlet. When the original air volume distribution ratio of the four air outlets is 1:1:1:1 and the total air volume is 400m3 / h, the air volume allocated to each air outlet is 100m3 / h. At this time, if the blade opening of the first air outlet is reduced by half, the target air volume of the first air outlet is 50m3 / h. At this time, the target total air volume is 350m3 / h, and the target air volume distribution ratio becomes 0.5:1:1:1. Then, the opening ratio between the air outlets is 0.5:1:1:1. Then, according to the opening ratio and the current damper opening corresponding to each air outlet, since only the damper opening corresponding to the target air outlet can be adjusted at this time, the damper opening of the target air outlet can be reduced by half. Therefore, the target air outlet is the air outlet to be adjusted, and the target damper opening is the current damper opening of the target air outlet multiplied by 0.5. After determining the target damper opening, the damper opening of the air outlet to be adjusted, i.e., the target air outlet, is adjusted to the target damper opening. At this time, the target total air volume can be distributed among the air outlets at the target air volume distribution ratio of 0.5:1:1:1.

[0090] In addition, if the blade opening of the first air outlet is doubled, the target air volume of the first air outlet is 200m3 / h. At this time, the target total air volume is 500m3 / h, and the target air volume distribution ratio becomes 2:1:1:1. When adjusting the air volume generated by the blower to the target total air volume, the damper opening of the air outlet also needs to be changed accordingly so that the target total air volume is distributed among the air outlets according to the target air volume distribution ratio. When adjusting the damper opening of the air outlet, it is necessary to adjust it in combination with the current damper opening of each air outlet and the target air volume distribution ratio. In this example, if the current damper opening of the first air outlet is already the maximum and the damper opening cannot be increased further, the damper opening of the remaining air outlets can be reduced by half to achieve the target total air volume distributed among the air outlets according to the target air volume distribution ratio. At this time, the air outlets to be adjusted are the remaining air outlets. In this example, the target damper opening is the current damper opening of the target air outlet multiplied by 0.5. After determining the target damper opening, the damper openings of the air outlets to be adjusted, i.e., the remaining air outlets, are adjusted to the target damper openings. At this time, the target total air volume can be distributed among the air outlets at the target air volume distribution ratio of 2:1:1:1.

[0091] The above-mentioned implementation scheme of the present application, by adjusting the air door opening of at least one air outlet, can make the air volume of the target air outlet meet the user's adjustment purpose when the blade opening of the target air outlet changes, and at the same time, other air outlets will not be affected by the change of the air volume of the target air outlet and maintain the initial air volume, thereby not changing the air outlet speed of other air outlets.
