For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0032] Figure 1 The flowchart of the first embodiment of a method for controlling air conditioning energy consumption provided by the present application is shown, and the method is executed by a vehicle. Figure 1 As shown, the method comprises the following steps:

[0033] Step S110: Detect whether the target seat is occupied;

[0034] Among them, by detecting whether the target seat is occupied, it is determined whether the air outlet corresponding to the unoccupied target seat needs to be closed. Specifically, a seat weight sensor or a camera can be used to collect a portrait to determine whether the target seat is occupied.

[0035] Step S120: If no one is on board, obtain the cabin temperature value;

[0036] If there is no one in the seat, the air outlet corresponding to the unoccupied target seat needs to be closed, and the time to close the air outlet corresponding to the target seat is determined by obtaining the cabin temperature value.

[0037] Step S130: obtaining an actual temperature difference value according to the cabin temperature value and the target operating temperature value of the air conditioner;

[0038] Among them, the cabin temperature value is the actual temperature value in the cabin, and the target operating temperature value of the air conditioner is the temperature value set by the user through the large-screen display at which the air conditioner needs to run. The actual temperature difference is obtained by obtaining the cabin temperature value and the target operating temperature value of the air conditioner to determine whether the air outlet corresponding to the unoccupied target seat can be closed at this moment. When the actual temperature value is too large, the heat exchange effect cannot be achieved, thereby failing to better meet the passengers' expected experience.

[0039] Step S140: If the actual temperature difference is less than the preset temperature difference, the air outlet corresponding to the target seat is controlled to be closed, and the air volume is controlled to drop to the target air volume threshold;

[0040] Among them, when the actual temperature difference is less than the preset temperature difference, it means that the cabin temperature value is slightly different from the target operating temperature value of the air conditioner, which can meet the passengers' experience; and the air volume of the occupied seats is controlled to drop to the target air volume threshold, so that the air conditioner's blower reduces the power and air output, thereby achieving energy saving of the air conditioner.

[0041] By detecting whether the target seat is occupied, if no one is sitting there, the cabin temperature value is obtained, and the actual temperature difference is obtained based on the cabin temperature value and the target operating temperature value of the air conditioner to determine whether to close the air outlet corresponding to the unoccupied target seat; if the actual temperature difference is less than the preset temperature difference, the air outlet corresponding to the unoccupied target seat is controlled to be closed, and the air volume is controlled to drop to the target air volume threshold, so that the air conditioner blower reduces the power output air volume, thereby achieving energy saving of the air conditioner.

[0042] Figure 2 The flowchart of the second embodiment of the method for controlling air conditioning energy consumption provided by the present application is shown, and the method is executed by a car. Figure 2 As shown, if the target seat is a front seat, the method includes the following steps:

[0043] Step S210: Detect whether the front seat is occupied;

[0044] Step S220: If at least one of the front seats is unoccupied, obtaining the front cabin temperature value;

[0045] If at least one of the front seats is unoccupied, it means that energy saving can be achieved by closing the air outlet corresponding to the unoccupied seat. A return air temperature sensor dedicated to detecting the front area is set in the front cockpit; specifically, the front cabin temperature value detected by the return air temperature sensor set in the front cabin area is obtained, and the return air temperature sensor in the front cabin area can be set at the front non-air outlet to detect the spatial environment temperature of the passengers.

[0046] Step S230: Obtaining a front row actual temperature difference value according to the front row cabin temperature value and the front row operating temperature value of the air conditioner;

[0047] Among them, the air-conditioning temperature values ​​of the front cockpit area and the rear cockpit area can be controlled separately, and the front row working temperature value of the air-conditioning can be set separately through the front row control screen.

[0048] Step S240: If the actual temperature difference of the front row is less than the preset temperature difference of the front row, the air outlet corresponding to the unoccupied seat in the front row is controlled to be closed, and the air volume of the front row air outlet is controlled to drop to the front row target air volume threshold;

[0049] Among them, the cabin temperature value includes the front row cabin temperature value; the target operating temperature value of the air conditioner includes the front row operating temperature value; the preset temperature difference includes the front row preset temperature difference; and the target air volume threshold includes the front row target air volume threshold.

[0050] In this embodiment, if the actual temperature difference in the front row is less than the preset temperature difference in the front row, it means that the temperature value of the front cabin is slightly different from the front row target operating temperature value of the air conditioner, which can satisfy the passengers' sense of experience; the air volume sources of the front cabin area and the rear cabin area are independently set, because the air volume source of each air outlet in the front cabin area is consistent and is output by the same blower; when one or more of the air outlets are closed, the air volume of the other open air outlets will increase, and by controlling the air volume of the occupied seats to drop to the front row target air volume threshold, on the one hand, the air volume of the air conditioner blower can be reduced to output air volume, thereby achieving energy saving of the air conditioner, and on the other hand, it can ensure that the air volume of the air outlets at the occupied seats is not too large to affect the passengers' sense of experience.

[0051] It should be noted that this method is applicable to the case where there are one or more front seats; each target seat may correspond to one or more air outlets, and when the target seat is unoccupied, the air outlets of the unoccupied seat are controlled to be closed. For example, in this embodiment, each seat in the front row may correspond to two air outlets. When there are two seats in the front row, specifically, the front row temperature threshold can be set to 10°C, and if one of the seats is unoccupied, the air volume can be controlled to drop to 40% of the original air volume; when the front row seat is unoccupied, its front row target air volume is set to 0, that is, the front row blower is controlled to be closed; the front row target air volume threshold is set according to actual needs.

[0052] Figure 3 The flowchart of the third embodiment of the method for controlling air conditioning energy consumption provided by the present application is shown, and the method is executed by a car. Figure 3 As shown, if the target seat is a back seat, the method includes the following steps:

[0053] Step S310: Detect whether there is someone sitting in the rear seat;

[0054] Step S320: If any three seats in the rear seats are unoccupied, obtain the rear cabin temperature value;

[0055] If at least three seats in the rear row are unoccupied, it means that energy saving can be achieved by closing the air outlets corresponding to the unoccupied seats. A return air temperature sensor dedicated to detecting the rear area is set in the rear cockpit; specifically, the rear cabin temperature value detected by the return air temperature sensor set in the rear cabin area is obtained; the return air temperature sensor in the rear area can be set in the last row of seats to detect the spatial environment temperature of the passengers.

[0056] Step S330: obtaining a rear row actual temperature difference value according to the rear row cabin temperature value and the rear row operating temperature value of the air conditioner;

[0057] Among them, the air-conditioning temperature values ​​of the rear cockpit area and the rear cockpit area can be controlled separately, and the rear working temperature value of the air-conditioning can be set separately through the rear control screen; specifically, the rear working temperature value of the air-conditioning can be set through the control screen of the second row area.

[0058] Step S340: If the actual temperature difference of the rear row is less than the first preset temperature difference of the rear row, the air outlet corresponding to the unoccupied seat in the rear row is controlled to be closed, and the air volume of the rear row air outlet is controlled to drop to the first rear row target air volume threshold;

[0059] Among them, the cabin temperature value includes the rear cabin temperature value; the target operating temperature value of the air conditioner includes the rear target operating temperature value; the preset temperature difference includes the first rear preset temperature difference; and the target air volume threshold includes the first rear target air volume threshold.

[0060] In this embodiment, if the actual rear row temperature difference is less than the first rear row preset temperature difference, it means that the rear cabin temperature value is slightly different from the rear row target operating temperature value of the air conditioner, which can satisfy the passenger experience; the air volume sources of the front cabin area and the rear cabin area are set independently, because the air volume source of each air outlet in the rear cabin area is consistent and output by the same blower; when one or more of the air outlets are closed, the air volume of the other open air outlets will increase, and by controlling the air volume of the occupied seats to drop to the first rear row target air volume threshold, on the one hand, the air volume of the air conditioner blower can be reduced to output air volume, thereby achieving energy saving of the air conditioner, and on the other hand, it can ensure that the air volume of the air outlets at the occupied seats is not too large to affect the passenger experience.

[0061] It should be noted that this method is applicable to the case where there are one or more rear seats; each target seat may correspond to one or more air outlets. When the target seat is unoccupied, the air outlets of the unoccupied seats are controlled to be closed. For example, each seat in the rear row may correspond to one air outlet. When there are four rear seats, specifically, the rear temperature threshold can be set to 10°C. If three of the seats are unoccupied, the air volume can be controlled to drop to 40% of the original air volume. When the rear seats are unoccupied, the front target air volume is set to 0, that is, the rear blower is controlled to be closed. The rear target air volume threshold is set according to actual needs.

[0062] Figure 4 The flowchart of the fourth embodiment of the method for controlling air conditioning energy consumption provided by the present application is shown, and the method is executed by a car. Figure 4As shown, if the actual temperature difference of the rear row is less than the first preset temperature difference of the rear row, the air outlet corresponding to the unoccupied seat in the rear row is controlled to be closed, and the air volume of the rear row air outlet is controlled to drop to the first rear row target air volume threshold, further comprising the following steps:

[0063] Step S341A: If one of the second row seats is unoccupied and the actual temperature difference of the rear row is less than the second rear row preset temperature difference, the air outlet of the third row seat is controlled to be closed, and the air volume of the rear row air outlet is controlled to drop to the second rear row target air volume threshold;

[0064] Among them, there can be 4 seats in the back row. If one of the second row seats is unoccupied, it means that there are 2 unoccupied seats in the third row. At this time, there is only one passenger in the back row, and the heat load generated is less. When the actual temperature difference in the back row is less than the second rear row preset temperature difference, the air outlet of the unoccupied third row seat can be closed first, and the air volume of the rear air outlet can be controlled to drop to the second rear row target air volume threshold, so that the air blower of the air conditioner can reduce the power output air volume in advance, further realizing the energy saving of the air conditioner, and on the other hand, it can ensure that the air volume of the air outlet of the seat where someone is sitting is not too large to affect the experience of the second row passengers. For example, the second rear row preset temperature difference can be set to 15°C, and the second rear row target air volume threshold can be reduced to 30% of the original air volume.

[0065] Step S342A: If the actual temperature difference of the rear row is less than the first preset temperature difference of the rear row, the air outlets corresponding to the unoccupied seats in the second row are controlled to be closed, and the air volume of the rear row air outlets is controlled to drop to the first rear row target air volume threshold;

[0066] Wherein, the preset temperature difference value also includes the second rear row preset temperature difference value; the target air volume threshold value also includes the second target air volume threshold value;

[0067] Among them, the first rear row preset temperature difference is smaller than the second rear row preset temperature difference. When the rear row actual temperature difference is smaller than the first rear row preset temperature difference, it is closer to the rear row working value of the air conditioner set by the passenger, which can better meet the passenger's experience. For example, the second rear row actual temperature difference can be specifically set to 10°C, and the second rear row target air volume threshold can be reduced to 40% of the original air volume.

[0068] Figure 5 The flowchart of the fifth embodiment of the method for controlling air conditioning energy consumption provided by the present application is shown, and the method is executed by a car. Figure 5As shown, if the actual temperature difference of the rear row is less than the first preset temperature difference of the rear row, the air outlet corresponding to the unoccupied seat in the rear row is controlled to be closed, and the air volume of the rear row air outlet is controlled to drop to the first rear row target air volume threshold, further comprising the following steps:

[0069] Step S341B: If one of the third row seats is unoccupied and the actual temperature difference of the rear row is less than the second rear row preset temperature difference, the air outlet of the second row seat is controlled to be closed, and the air volume of the rear row air outlet is controlled to drop to the third rear row target air volume threshold;

[0070] There can be 4 seats in the back row. If one of the seats in the third row is unoccupied, it means that there are 2 seats in the second row that are unoccupied. At this time, there is only one passenger in the back row, and the heat load generated is relatively small. When the actual temperature difference in the back row is less than the second rear row preset temperature difference, the air outlet of the unoccupied third row seat can be closed first, and the air volume of the rear air outlet can be controlled to drop to the second rear row target air volume threshold, so that the air blower of the air conditioner can reduce the power output air volume in advance, further realizing the energy saving of the air conditioner, and on the other hand, it can ensure that the air volume of the air outlet of the seat where someone is sitting is not too large to affect the experience of the third row passengers. For example, the second rear row preset temperature difference can be set to 15°C, and the second rear row target air volume threshold can be reduced to 30% of the original air volume.

[0071] Step S342B: If the actual temperature difference of the rear row is less than the first preset temperature difference of the rear row, the air outlets corresponding to the unoccupied seats in the third row are controlled to be closed, and the air volume of the rear row air outlets is controlled to drop to the first rear row target air volume threshold;

[0072] Wherein, the preset temperature difference value also includes the second rear row preset temperature difference value; the target air volume threshold value also includes the second target air volume threshold value;

[0073] Among them, the first rear row preset temperature difference is smaller than the second rear row preset temperature difference. When the rear row actual temperature difference is smaller than the first rear row preset temperature difference, it is closer to the rear row working value of the air conditioner set by the passenger, which can better meet the passenger's experience. For example, the second rear row actual temperature difference can be specifically set to 10°C, and the second rear row target air volume threshold can be reduced to 40% of the original air volume.

[0074] Figure 6 The sixth embodiment of the method for controlling air conditioning energy consumption provided by the present application is shown in the flowchart, and the method is executed by a car. Figure 6 As shown, if the target seat is a back seat, the method comprises the following steps:

[0075] Step S510: Detect whether there is someone sitting in the rear seat;

[0076] Step S520: If any two seats in the rear seats are unoccupied, obtain the rear cabin temperature value;

[0077] If two of the rear seats are unoccupied, it means that energy saving can be achieved by closing the air outlets corresponding to the unoccupied seats. A return air temperature sensor dedicated to detecting the rear area is set in the rear cockpit; specifically, the rear cabin temperature value detected by the return air temperature sensor set in the rear cabin area is obtained; the return air temperature sensor in the rear area can be set in the last row of seats to detect the spatial environment temperature of the passengers.

[0078] Step S530: Obtaining a rear row actual temperature difference value according to the rear row cabin temperature value and the rear row operating temperature value of the air conditioner;

[0079] Among them, the air-conditioning temperature values ​​of the front cabin area and the rear cabin area can be controlled separately, and the rear working temperature value of the air-conditioning can be set separately through the control screen in the rear row; specifically, the rear working temperature value of the air-conditioning can be set through the control screen in the second row area.

[0080] Step S540: If the rear row actual temperature difference is less than the third rear row preset temperature difference, the air outlets corresponding to the unoccupied seats in the rear row are controlled to be closed, and the air volume of the rear row air outlets is controlled to drop to the third rear row target air volume threshold;

[0081] Among them, the cabin temperature value includes the rear cabin temperature value; the target operating temperature value of the air conditioner includes the rear operating temperature value; the preset temperature difference includes the third rear row preset temperature difference; and the target air volume threshold includes the third rear row target air volume threshold.

[0082] In this embodiment, this method is applicable to the case where there are one or more rear seats; each target seat may correspond to one or more air outlets, and when the target seat is unoccupied, the air outlets of the unoccupied seats are controlled to be closed. For example, each seat in the rear row may correspond to one air outlet. When there are four rear seats, specifically, since the heat exchange load generated by the human body when there are two people in the rear row is greater than the heat exchange load generated when there is one person, the rear temperature threshold may be set to 9°C, and if two of the seats are unoccupied, the air volume may be controlled to drop to 30% of the original air volume.

[0083] Figure 7 The flowchart of the seventh embodiment of the method for controlling air conditioning energy consumption provided by the present application is shown, and the method is executed by a car. Figure 7As shown, if the target seat is a back seat, the method comprises the following steps:

[0084] Step S610: Detect whether there is someone sitting in the rear seat;

[0085] Step S620: If one of the rear seats is unoccupied, obtain the rear cabin temperature value;

[0086] If one of the rear seats is unoccupied, it means that energy saving can be achieved by closing the air outlet corresponding to the unoccupied seat. A return air temperature sensor dedicated to detecting the rear area is set in the rear cockpit; specifically, the rear cabin temperature value detected by the return air temperature sensor set in the rear cabin area is obtained; the return air temperature sensor in the rear area can be set in the last row of seats to detect the spatial environment temperature of the passengers.

[0087] Step S630: Obtaining a rear-row actual temperature difference value according to the rear-row cabin temperature value and the rear-row operating temperature value of the air conditioner;

[0088] Among them, the air-conditioning temperature values ​​of the rear cockpit area and the rear cockpit area can be controlled separately, and the rear working temperature value of the air-conditioning can be set separately through the rear control screen; specifically, the rear working temperature value of the air-conditioning can be set through the control screen of the second row area.

[0089] Step S640: If the actual temperature difference of the rear row is less than the fourth rear row preset temperature difference, the air outlet corresponding to the unoccupied seat in the rear row is controlled to be closed, and the rear row air volume is controlled to drop to the fourth rear row target air volume threshold;

[0090] Among them, the cabin temperature value includes the rear cabin temperature value; the target operating temperature value of the air conditioner includes the rear operating temperature value; the preset temperature difference includes the fourth rear row preset temperature difference; and the target air volume threshold includes the fourth rear row target air volume threshold.

[0091] In this embodiment, this method is applicable to the case where there are one or more rear seats; each target seat may correspond to one or more air outlets, and when the target seat is unoccupied, the air outlets of the unoccupied seats are controlled to be closed. For example, each seat in the rear row may correspond to one air outlet. When there are four rear seats, specifically, since there are more passengers, the heat exchange load generated by the human body is greater, and the rear temperature threshold may be set to 8°C. If one of the seats is unoccupied, the air volume may be controlled to drop to 20% of the original air volume.
