DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0023] In order to solve the above problems, the first embodiment of the present invention proposes a vehicle air-conditioning system, which can provide air volume to the front and rear rows of the vehicle, and independently adjust the air volume of different air outlets in the rear row of the vehicle, thereby reducing the overall weight and cost of the vehicle.

[0024] Reference below Figure 1 The vehicle air conditioning system 100 according to the embodiment of the present invention is described. The vehicle air conditioning system 100 includes a plurality of rear air outlets 14 , a front air outlet 3 , a first blower 4 and a second blower 5 .

[0025] Among them, multiple rear air outlets 14 are arranged at the rear row of the vehicle; the front air outlet 3 is used to provide air volume for the front driver's seat of the vehicle; the first blower 4 is connected with the multiple rear air outlets 14 and the front air outlet 3, and the first blower is used to deliver air volume to the rear air outlet 14 and / or the front air outlet 3 according to the front air outlet gear and the rear air outlet gear given by the user, that is, the first blower 4 delivers air volume to the rear air outlet 14 and the front air outlet 3 according to the front air outlet gear and the rear air outlet gear given by the user, or the first blower 4 delivers air volume to the rear air outlet 14 according to the front air outlet gear and the rear air outlet gear given by the user, or, or the first blower 4 delivers air volume to the front air outlet 3 according to the front air outlet gear and the rear air outlet gear given by the user; the second blower is connected with the multiple rear air outlets 14, and the second blower 5 is used to compensate the air volume at the rear air outlet 14 according to the front air outlet gear and the rear air outlet gear given by the user.

[0026] Specifically, when the user turns on the front and rear air outlet functions, the first blower 4 provides air volume to the front air outlet 3 according to the front air outlet gear position given by the user, so as to ensure that the air volume of the front air outlet 3 meets the user's air volume requirement for the front driver's seat, and at the same time, the first blower 4 provides air volume to multiple rear air outlets 14, wherein, there will be air volume loss when the air from the first blower 4 reaches different rear air outlets of the vehicle after the air is discharged. If the air volume reaching the multiple rear air outlets 14 after the air from the first blower 4 cannot meet the rear air outlet gear position given by the user, that is, the air volume of the multiple rear air outlets 14 cannot meet the user's requirement for the rear air volume of the vehicle, therefore, the present application compensates the air volume at the multiple rear air outlets 14 through the second blower 5, that is, provides the multiple rear air outlets 14 with the air volume after the loss according to the rear air outlet gear position and the front air outlet gear given by the user regarding the multiple rear air outlets 14, so as to determine the compensating wind volume provided by the second blower The gear or speed corresponding to the amount is used to compensate for the air volume at multiple rear air outlets 14. Alternatively, when the user does not turn on the front air outlet function but turns on the rear air outlet function, the first blower provides air volume to multiple rear air outlets 14 according to the rear air outlet gear, and the gear of the first blower is controlled to be higher than the rear air outlet gear. For example, the gear of the first blower can be the sum of the rear air outlet gear and the loss air volume gear, so that the air volume of multiple rear air outlets 14 reaches the air outlet gear set by the user. Therefore, the present application connects the first blower 4 and the second blower 5 to the multiple rear air outlets 14, so as to realize compensation for the air volume of different rear air outlets 14 of the vehicle, thereby avoiding the problem of insufficient air volume at different rear air outlets 14 of the vehicle under the rear air outlet gear set by the user, so that the actual air volume of different rear air outlets of the vehicle reaches the air outlet gear set by the user, and the weight and cost of the vehicle are extremely low.

[0027] Exemplarily, the first air outlet 1 can be located on the right B-pillar of the vehicle; the second air outlet 2 can be set on the left B-pillar of the vehicle, or the first air outlet 1 and the second air outlet 2 are set at different positions in the rear row of the vehicle; the front air outlet 3 is used to provide air volume for the front driver's seat of the vehicle; the first blower 4 is connected to the first air outlet 1, the second air outlet 2, and the front air outlet 3, and the first blower 4 is used to deliver air volume to the first air outlet 1, the second air outlet 2 and / or the front air outlet 3 according to the front air outlet gear and the rear air outlet gear given by the user, and the first blower 4 is set on the instrument panel; the second blower 5 is connected to the first air outlet 1 and the second air outlet 2, and the second blower 5 is set on the auxiliary instrument panel, and the second blower 5 is used to compensate the air volume at the first air outlet 1 according to the front air outlet gear and the rear air outlet gear given by the user, and to compensate the air volume at the second air outlet 2 according to the front air outlet gear and the rear air outlet gear given by the user.

[0028] Specifically, when the user turns on the front and rear air outlet functions, the first blower 4 provides air volume to the front air outlet 3 according to the front air outlet gear position given by the user, so as to ensure that the air volume of the front air outlet 3 meets the user's air volume requirement for the front driver's seat, and at the same time, the first blower 4 provides air volume to the first air outlet 1 and the second air outlet 2. However, there will be air volume loss when the air from the first blower 4 reaches different air outlets at the rear of the vehicle after the air is discharged. If the air volume reaching the first air outlet 1 and the second air outlet 2 after the air from the first blower 4 cannot meet the rear air outlet gear position given by the user, that is, the air volume of the first air outlet 1 and the second air outlet 2 cannot meet the user's requirement for the rear air volume of the vehicle; the present application compensates the air volume at the first air outlet 1 and the second air outlet 2 by the second blower 5, that is, provides air volume for multiple rear air outlets according to the rear air outlet gear position and front air outlet gear position given by the user regarding the first air outlet 1 and the second air outlet 2. The air volume after the loss is determined, and the gear or speed corresponding to the compensatory air volume provided by the second blower is determined to compensate for the air volume at the first air outlet 1 and the second air outlet 2. Alternatively, when the user does not turn on the front air outlet function but turns on the rear air outlet function, the first blower provides air volume to the first air outlet and the second air outlet according to the rear air outlet gear. For example, the gear of the second blower 5 is controlled to be the sum of the rear air outlet gear and the lost air volume gear to compensate for the air volume at the first air outlet 1 and the second air outlet 2. Therefore, the present application connects the first blower 4 and the second blower 5 to multiple rear air outlets, so as to realize compensation of the air volume of different rear air outlets of the vehicle, thereby avoiding the problem of insufficient air volume at different rear air outlets of the vehicle when the rear air outlet gear is set by the user, so that the actual air volume of different rear air outlets of the vehicle reaches the air outlet gear set by the user, and the weight and cost of the vehicle are extremely low.

[0029] According to the vehicle air-conditioning system of an embodiment of the present invention, based on the structure that the first blower 4 and the second blower 5 are connected with multiple rear air outlets 14, on the basis of providing air volume for the front driver's seat of the vehicle through the first blower 4, the second blower 5 compensates the air volume for different rear air outlets of the vehicle, so that the actual air volume of different rear air outlets of the vehicle reaches the air outlet gear set by the user. Therefore, compared with the prior art of configuring two blowers in the rear row of the vehicle to realize the individual adjustment of the air volume of different rear air outlets of the vehicle, the present application connects the first blower 4 and the second blower 5 with multiple rear air outlets, thereby realizing the individual adjustment of the air volume of different rear air outlets of the vehicle and effectively reducing the overall weight and cost of the vehicle.

[0030] In some embodiments, Figure 1 As shown, the vehicle air conditioning system 100 further includes: a first air door 6 , a second air door 7 , a first air duct 8 , a second air duct 9 , a third air duct 10 and a third air door 11 .

[0031] Among them, the first damper 6 is arranged between the first air outlet 1 and the second blower 5, and the first damper 6 is used to adjust the air outlet volume of the first air outlet 1; the second damper 7 is arranged between the second air outlet 2 and the second blower 5, and the second damper 7 is used to adjust the air outlet volume of the second air outlet 2; the first blower 4 and the second blower 5 are connected through the first air duct 8; one end of the second air duct 9 is connected to the second blower 5, and the other end of the second air duct 9 is connected to the first air outlet 1; one end of the third air duct 10 is connected to the second blower 5, and the other end of the third air duct 10 is connected to the second air outlet 2; the third damper 11 is arranged on the first air duct 8, and the third damper 11 is used to control whether the air volume delivered by the first blower 4 enters the first air outlet 1 and the second air outlet 2. In addition, it should be noted that the air volume provided by the first blower 4 to the second air duct 9 and the third air duct 10, the first damper 6 and the second damper 7 do not adjust the air volume delivered by the first blower to the rear air duct, but adjust the air volume that has already flowed into the second air duct 9 and the third air duct 10.

[0032] It can be seen from Table 1 that when the second blower is not turned on, the wind generated by the first blower will have a certain amount of air loss after passing through the first air duct, and the actual air volume reaching the first air outlet and the second air outlet in the rear row of the vehicle is lower than the air volume at the front air outlet. For example, when the first blower delivers air to the first air outlet and the second air outlet through the air duct and the second blower 5 does not deliver air to the first air outlet and the second air outlet, there will be a certain amount of air loss, and the amount of air loss is different for different vehicles. For example, the amount of air loss can be 0.5 gear, 1 gear or other gears, with a loss of 1 gear. Taking the air volume as an example, if the first blower gear is gear 1, the air outlet gear of the first air outlet and the second air outlet gear are gear 0; if the first blower gear is gear 2, the air outlet gear of the first air outlet and the second air outlet gear are gear 1; if the first blower gear is gear 3, the air outlet gear of the first air outlet and the second air outlet gear are gear 2; if the first blower gear is gear 4, the air outlet gear of the first air outlet and the second air outlet gear are gear 3; if the first blower gear is gear 5, the air outlet gear of the first air outlet and the second air outlet gear are gear 4; if the first blower gear is gear 6, then The air outlet gear of the first air outlet and the air outlet gear of the second air outlet are gear 5; if the gear of the first blower is gear 7, the air outlet gear of the first air outlet and the air outlet gear of the second air outlet are gear 6. In order to provide air volume compensation for different air outlets in the rear row of the vehicle, the vehicle air-conditioning system of the present application is provided with a second blower 5 to compensate for the air volume at the first air outlet 1 and the second air outlet 2. That is to say, if the first blower 4 provides air volume for the first air outlet, the second air outlet and the front air outlet according to the gear shown in Table 1, the air volume at the first air outlet 1 and the second air outlet 2 is compensated by the second blower 5, wherein the first The second blower 5 can achieve up to 7 levels of adjustment. For instance, taking the loss of 1 level of air volume as an example, if the front air outlet gear is 3 levels and the rear air outlet gears are both 3 levels, the gear of the second blower is controlled to be 1 level to provide 1 level of compensation air volume. In other words, the air volume reaching different rear air outlets of the vehicle after the first blower 4 blows out air cannot meet the rear air outlet gear set by the user. The second blower 5 is controlled to work and the gear size of the second blower 5 is controlled according to the front air outlet gear, the loss air volume gear and the rear air outlet gear, so that the air volume at different rear air outlets of the vehicle meets the air outlet gear set by the user.

[0033] Table 1

[0034] Specifically, when the user turns off the rear exhaust air function, the third air door 11 is controlled to be closed. At this time, the air volume generated by the first blower cannot be delivered to the second blower 5, and also cannot be delivered to the first air outlet 1 and the second air outlet 2. When the user turns on the rear exhaust air function, the third air door 11 is controlled to be opened, and the first blower 4 delivers the generated air volume to the second blower 5 through the first air duct. At the same time, the second blower 5 adjusts the air volume of the first air outlet according to the front exhaust air gear and the rear exhaust air gear and the loss air volume gear given by the user. The air volume generated by the first blower 4 and the compensating air volume generated by the second blower 5 are compensated for at the first air outlet 1 and the second air outlet 2, the air volume generated by the first blower 4 and the compensating air volume generated by the second blower 5 are transported to the first air outlet 1 through the second air duct 9, and the air volume generated by the first blower 4 and the compensating air volume generated by the second blower 5 are transported to the second air outlet 2 through the third air duct 10. Therefore, the present application compensates for the air volume at the first air outlet 1 and the second air outlet 2 through the second blower 5, so that the air volume at different air outlets in the rear row of the vehicle reaches the air outlet gear set by the user.

[0035] In the related art, when the temperature inside the vehicle is adjusted by air conditioning, different air outlets are set at the rear of the vehicle to adjust the air temperature in order to take care of the rear passengers. Passengers in the vehicle may have different requirements for air volume, so in order to achieve independent adjustment of the air volume of different air outlets in the rear of the vehicle, two additional blowers are usually configured at the rear of the vehicle to adjust the air volume of different air outlets in the rear of the vehicle, but this approach will increase the overall weight and cost of the vehicle. Therefore, in order to achieve individual adjustment of the air volume of different air outlets in the rear row of the vehicle, the first air door 6 and the second air door 7 are set in the present application. By adjusting the opening of the first air door 6 and the second air door 7, the air volume of the first air outlet 1 and the second air outlet 2 can be adjusted respectively, so that the air volume of the first air outlet 1 and the second air outlet 2 are different. Therefore, compared with the prior art of configuring two blowers in the rear row of the vehicle to achieve individual adjustment of the air volume of different air outlets in the rear row of the vehicle, the present application only sets the first air door 6 and the second air door 7, which can achieve individual adjustment of the air volume of different air outlets in the rear row of the vehicle and effectively reduce the overall weight and cost of the vehicle.

[0036] In some embodiments, Figure 1 As shown, the vehicle air conditioning system 100 further includes an armrest box 12 and a fourth air door.

[0037] Among them, the armrest box 12 is located between the main driver's seat and the co-driver's seat of the vehicle, and a fourth air duct 13 is arranged in the armrest box 12. One end of the fourth air duct 13 is connected to the second air duct 9 through the first air door 6, and the other end of the fourth air duct 13 is connected to the third air duct 10 through the second air door 7. Among them, the first air door 6 is also used to adjust the ventilation amount entering the second air duct 9 and the fourth air duct, and the second air door 7 is also used to adjust the ventilation amount entering the third air duct 10 and the fourth air duct 13. After the wind in the second air duct and the third air duct enters the fourth air duct 13, the air volume is provided for the items inside the armrest box through the air supply port of the armrest box 12. Since the armrest box 12 is not a closed space, it can flow out through the gap of the armrest box, for example, through the gap of the armrest box cover. Alternatively, if the wind in the second air duct 9 enters the fourth air duct 13 through the first air door 6, when the armrest box 12 needs to discharge air, the fourth air duct 1 can also be opened by adjusting the opening of the first air door 6. 3 flows out of the armrest box. On the contrary, if the wind from the third air duct 10 enters the fourth air duct 13 through the second air door 7, when the armrest box 12 needs to discharge air, the wind from the fourth air duct 13 can also be made to flow out of the armrest box by adjusting the opening of the second air door 7; the fourth air door is located on the heat exchange air outlet duct of the vehicle air-conditioning system 100, and the heat exchange air outlet duct is used to transport the air generated by the vehicle air-conditioning system 100 after heat exchange into the fourth air duct 13 through the first air duct 8. The fourth air door is used to adjust the ventilation volume entering the first air duct 8 from the heat exchange air outlet duct, that is, the fourth air door is used to adjust the mixing ratio of the air-conditioned air heated by the warm air core and the air-conditioned air cooled by the evaporator. Based on this, when the first air outlet and the second air outlet are closed, the armrest box set temperature given by the user is obtained, and the speed of the compressor and the opening of the fourth air door are controlled according to the set temperature of the armrest box to adjust the temperature of the armrest box so that the temperature of the armrest box meets the set temperature of the armrest box. The greater the opening of the fourth air door, the higher the temperature of the armrest box, and the higher the speed of the compressor, the higher the temperature of the armrest box.

[0038] Specifically, since the second blower 5 provides the same air volume to the second air duct 9 and the third air duct 10, in order to control the different air volumes of the first air outlet 1 and the second air outlet 2, the present application provides a fourth air duct 13 in the armrest box 12, wherein the fourth air duct 13 is connected to the second air duct 9 through the first air door 6, and the fourth air duct 13 is connected to the third air duct 10 through the second air door 7, that is, the first air door 6 and the second air door 7 are located at the air inlet of the fourth air duct 13, and the ventilation volume entering the second air duct 9 and the fourth air duct 13 can be increased or decreased by rotating the first air door 6, and the ventilation volume entering the third air duct can be increased or decreased by rotating the second air door 7. The ventilation volume of the air duct 10 and the fourth air duct 13. Based on this, when the air outlet position of the first air outlet 1 set by the user is different from the air outlet position of the second air outlet 2, the air volume flowing into the fourth air duct 13 is increased or decreased by adjusting the opening of the second air door 7, thereby reducing or increasing the air volume flowing from the third air duct 10 to the second air outlet, and the air volume flowing into the fourth air duct 13 is increased or decreased by adjusting the opening of the first air door 6, thereby reducing or increasing the air volume flowing from the second air duct 9 to the first air outlet, so that the air outlet of the first air outlet 1 and the second air outlet 2 meets the air outlet position set by the user, and at the same time, excess air volume can be provided for the armrest box.

[0039] In addition, it should be noted that the larger the opening of the first damper 6 and the second damper 7, the less the air inlet of the fourth air duct 13 is blocked, the more air flows to the armrest box, and the less air flows in the first air outlet 1 and the second air outlet 2. A second embodiment of the present invention provides an air conditioning control method, such as Figure 2 As shown, the air conditioning control method includes steps S1-S3, and the specific steps are as follows.

[0040] Step S1, obtaining the front air flow position and the rear air flow position specified by the user.

[0041] Specifically, the front row user selects the front air flow gear through the front air flow button as required, so as to control the air flow of the front air outlet 3 according to the front air flow gear; and the rear row user selects the rear air flow gear of the vehicle's multiple rear air outlets through the vehicle's rear air flow button as required, so as to control the air flow of the multiple rear air outlets 14 according to the rear air flow gear. Alternatively, the user can also input the front air flow gear and the rear air flow gear through the central control screen, thereby obtaining the front air flow gear and the rear air flow gear given by the user.

[0042] Step S2, controlling the working state of the first blower 4 according to the front air discharge gear position and the rear air discharge gear position.

[0043] Specifically, when the user turns on the front exhaust air flow function, the first blower 4 is controlled to work, and the standard air volume value corresponding to the front exhaust air flow gear is obtained. The speed or gear of the first blower 4 during the operation is controlled according to the standard air volume value. At the same time, if the user turns on the rear exhaust air flow function, the air volume provided by the first blower 4 can provide air volume for different rear air outlets of the vehicle. Thus, the first blower 4 is controlled to generate the air volume corresponding to the front exhaust air flow gear for output, thereby meeting the user's air volume requirements for the front driver's seat of the vehicle, and the rear exhaust air flow function can also be realized. When the user does not turn on the front exhaust air flow function but turns on the rear exhaust air flow function, the first blower 4 is controlled to work, and the standard air volume value corresponding to the rear exhaust air flow gear is obtained. The speed and gear of the first blower 4 during the operation are controlled according to the standard air volume value and the loss air volume corresponding to the rear exhaust air flow gear. Thus, the first blower 4 is controlled to generate the air volume and loss air volume corresponding to the rear exhaust air flow gear for output, thereby meeting the user's air volume requirements for the rear driver's seat of the vehicle.

[0044] Step S3, controlling the working state of the second blower 5, the opening degree of the first damper 6 and the opening degree of the second damper 7 according to the front air discharge gear position and the rear air discharge gear position.

[0045] Specifically, since the first blower 4 can provide the multiple rear air outlets 14 with the air volume corresponding to the front air outlet gear through the first air duct 8, the wind generated by the first blower 4 will have a certain air volume loss after passing through the air duct, so that the air volume out of the multiple rear air outlets 14 is reduced. Therefore, in the present application, when the first blower 4 is controlled to work according to the front air outlet gear and the rear air outlet gear and the air volume provided to the multiple rear air outlets 14 cannot meet the rear air outlet gear set by the user, the second blower 5 is controlled to work based on the front air outlet gear and the rear air outlet gear to provide air volume compensation to the multiple rear air outlets 14, that is, the air volume after loss is provided to the multiple rear air outlets 14 according to the rear air outlet gear and the front air outlet gear given by the user regarding the multiple rear air outlets 14, so as to determine the gear or speed corresponding to the compensatory air volume provided by the second blower, so as to adjust the air volume at the multiple rear air outlets 14 Compensation, or, when the user does not turn on the front air outlet function but turns on the rear air outlet function, the first blower provides air volume to multiple rear air outlets 14 according to the front air outlet gear and the rear air outlet gear. For example, when the first blower provides air volume to multiple rear air outlets 14 at the front air outlet gear, the air volume corresponding to the loss air volume gear will be lost, and the gear of the second blower is controlled to be the sum of the rear air outlet gear and the loss air volume gear to compensate for the air volume of multiple rear air outlets 14. Therefore, the present application connects the first blower 4 and the second blower 5 to the multiple rear air outlets 14, so as to realize the compensation of the air volume of different rear air outlets 14 of the vehicle, thereby avoiding the problem of insufficient air volume of different rear air outlets 14 of the vehicle when the rear air outlet gear is set by the user, so that the actual air volume of different rear air outlets of the vehicle reaches the air outlet gear set by the user, and the weight and cost of the vehicle are extremely low.

[0046] Exemplarily, multiple rear air outlets 14 have a first air outlet 1 and a second air outlet 2. After the user sets the front air outlet gear and the rear air outlet gear, if the front air outlet gear is higher than the rear air outlet gear, the first blower 4 provides the first air outlet 1 and the second air outlet 2 with an air volume corresponding to the front air outlet gear after air volume loss. If the air volume is greater than or equal to a standard air volume value corresponding to the rear air outlet gear, there is no need to control the second blower 5 to provide compensating air volume to the first air outlet 1 and the second air outlet 2. If the air volume is less than the standard air volume value corresponding to the rear air outlet gear, the second blower 5 operates to provide air volume compensation to the first air outlet 1 and the second air outlet 2, that is, the working state of the second blower 5 is controlled according to the front air outlet gear and the rear air outlet gear, wherein the working state includes the gear and the speed, to provide air volume compensation to the first air outlet 1 and the second air outlet 2; if the front air outlet gear When the exhaust air gear is less than or equal to the rear exhaust air gear, at this time, the air volume provided by the first blower 4 to the first air outlet 1 and the second air outlet 2 cannot meet the gear corresponding to the rear exhaust air gear, then the compensation air volume gear or compensation air volume speed is determined according to the rear exhaust air gear and the front exhaust air gear given by the user for the first air outlet 1 and the second air outlet 2, and the gear or speed of the second blower 5 is controlled to be the compensation air volume gear or compensation air volume speed to provide the first air outlet 1 and the second air outlet 2 with the lost air volume, so as to determine the gear or speed corresponding to the compensation air volume provided by the second blower, so as to provide air volume compensation for the first air outlet 1 and the second air outlet 2, that is, the second blower 5 is controlled to work according to the rear exhaust air gear to provide air volume compensation for the first air outlet 1 and the second air outlet 2 according to the rear exhaust air gear, so that the air volume of the first air outlet 1 and the second air outlet 2 meets the air outlet gear set by the user.

[0047] Therefore, in the present application, when the air volume provided to different rear air outlets by the first blower 4 when operating according to the front air outlet gear cannot meet the air volume corresponding to the air outlet gear set by the user, the air volume of different rear air outlets is compensated by the second blower 5, thereby avoiding the problem of insufficient air volume at different rear air outlets at the rear air outlet gear, thereby ensuring that the air volume of the first air outlet 1 and the second air outlet 2 meets the air outlet gear set by the user.

[0048] According to the air conditioning control method of an embodiment of the present invention, based on the structure that the first blower 4 and the second blower 5 are connected to the multiple rear air outlets 14, in this application, when the first blower 4 is controlled to work according to the front air outlet gear and the air volume provided to different rear air outlets cannot meet the air outlet gear set by the user, the second blower 5 is controlled to work according to the front air outlet gear and the rear air outlet gear to provide air volume compensation for the multiple rear air outlets 14, thereby avoiding the problem of insufficient air volume of the multiple rear air outlets at the rear air outlet gear, so that the air volume of the multiple rear air outlets 14 meets the air outlet gear set by the user.

[0049] In some embodiments, the working state of the second blower 5 is controlled according to the front row air outlet gear and the rear row air outlet gear, including: when the rear row air outlet gear is not 0 and the rear row air outlet gear is lower than the front row air outlet gear, or when the front row air outlet gear is 0 and any one of the rear row air outlet gears is not 0, the second blower 5 is controlled not to start; when the front row air outlet gear is not 0 and any one of the rear row air outlet gears is higher than or equal to the front row air outlet gear, the second blower 5 is controlled to start.

[0050] Specifically, the rear air outlet gear is a gear given by the user for multiple rear air outlets 14. When the rear air outlet gears are not 0 and the rear air outlet gears are lower than the front air outlet gears, or when the front air outlet gear is 0 and any of the rear air outlet gears is not 0, the air volume delivered by the first blower 4 is greater than the air volume of the rear air outlet gear set by the user for each rear air outlet 14. In other words, after the first blower 4 loses air volume when conveying air through the air duct, it can still meet the rear set gears of multiple rear air outlets 14. At this time, there is no need to control the second blower 5 to start to provide air volume compensation, and the second blower 5 is controlled not to start; or, when the front air outlet gear is 0 and any of the rear air outlet gears is not 0, the first blower 4 does not need to provide air volume to the front air outlet 3, and the gear of the first blower 4 is controlled to provide air volume higher than the rear air outlet gear. gear, for example, the gear of the first blower is controlled to be the sum of the rear exhaust airflow gear and the lost air volume gear. At this time, the air volume provided by the first blower 4 has excess air volume, so that after the air volume provided by the first blower 4 is lost when passing through the air duct, the air volume of the first air outlet 1 and the second air outlet 2 can still meet the rear exhaust airflow gear set by the user. There is no need to control the second blower 5 to start to provide air volume compensation, and the second blower 5 is controlled not to start; when the front exhaust airflow gear is not 0, and any gear of the rear exhaust airflow gear is higher than or equal to the front exhaust airflow gear, the air volume provided by the first blower 4 can only meet the front exhaust airflow gear set by the front exhaust air outlet 3, but cannot meet the rear exhaust airflow gear set by multiple rear exhaust air outlets 14, then the second blower 5 is controlled to start to provide air volume compensation for multiple rear exhaust air outlets 14, thereby ensuring that the air volume of multiple rear exhaust air outlets 14 meets the rear exhaust airflow gear set by the user.

[0051] In some embodiments, the rear air discharge gear includes a first rear air discharge gear and a second rear air discharge gear, and the working state of the second blower 5, the opening of the first damper 6, and the opening of the second damper 7 are controlled according to the front air discharge gear, the first rear air discharge gear, and the second rear air discharge gear, including: when the first rear air discharge gear and the second rear air discharge gear are not 0, and the first rear air discharge gear and the second rear air discharge gear are lower than the front air discharge gear, the second blower 5 is controlled not to start, and the opening of the first damper 6 is controlled according to the front air discharge gear and the first rear air discharge gear, and the opening of the second damper 7 is controlled according to the front air discharge gear and the first rear air discharge gear. And, when the front air discharge gear is not 0, and any of the first rear air discharge gear and the second rear air discharge gear is higher than or equal to the front air discharge gear, the second blower 5 is controlled to start, and the opening of the first damper 6 is controlled according to the first rear air discharge gear, and the opening of the second damper 7 is controlled according to the second rear air discharge gear.

[0052] Specifically, when the first rear air outlet gear and the second rear air outlet gear are both not 0, and the first rear air outlet gear and the second rear air outlet gear are both lower than the front air outlet gear, the air volume delivered by the first blower 4 is greater than the air volume corresponding to the rear air outlet gear, that is, after the first blower 4 loses air volume when conveying air through the air duct, the first rear air outlet gear and the second rear air outlet gear can still be satisfied. At this time, there is no need to control the second blower 5 to start to provide air volume compensation, or when the front air outlet gear is 0, and any of the first rear air outlet gear and the second rear air outlet gear is not 0, the first blower 4 does not need to provide air volume to the front air outlet 3, then by controlling the gear of the first blower 4 to be a gear higher than the rear air outlet gear, for example, controlling the gear of the first blower to be the sum of the rear air outlet gear and the lost air volume gear, at this time, the air volume provided by the first blower 4 has excess air volume, so that After the air volume provided by the first blower 4 is lost when passing through the air duct, the air volume of the first air outlet 1 and the second air outlet 2 can still meet the rear air outlet gear set by the user. There is no need to control the second blower 5 to start to provide air volume compensation, so the second blower 5 is controlled not to start. At the same time, the opening of the first damper 6 is controlled according to the front air outlet gear and the first rear air outlet gear, and the opening of the second damper 7 is controlled according to the front air outlet gear and the second rear air outlet gear. In other words, the air volume provided by the first blower 4 to the first air outlet 1 and the second air outlet 2 is determined according to the front air outlet gear, and the air volume of the first air outlet 1 and the second air outlet 2 is determined according to the first rear air outlet gear and the second rear air outlet gear, and the opening of the first damper 6 and the second damper 7 is controlled to achieve separate adjustment of the air volume of different rear air outlets of the vehicle, and at the same time, ensure that the air volume of the first air outlet 1 and the second air outlet 2 meets the air outlet gear set by the user.

[0053] Furthermore, when the front air outlet gear is not 0, and any one of the first rear air outlet gear and the second rear air outlet gear is higher than or equal to the front air outlet gear, the air volume provided by the first blower 4 can only meet the front air outlet gear set for the front air outlet 3, but cannot meet the rear air outlet gear set for the rear air outlet, then the second blower 5 is controlled to start to provide air volume compensation for the first air outlet 1 and the second air outlet 2, and the size of the compensation air volume is determined according to the front air outlet gear, the first rear air outlet gear, the second rear air outlet gear and the lost air volume, so as to determine the gear of the second blower according to the size of the compensation air volume, and the gear of the second blower is determined according to the front air outlet gear. The first air door 6 and the second air door 7 are controlled according to the front air outlet gear and the second rear air outlet gear. That is to say, the air volume provided by the first blower 4 to the first air outlet 1 and the second air outlet 2 is determined according to the front air outlet gear, and the air volume of the first air outlet 1 and the second air outlet 2 is determined according to the first rear air outlet gear and the second rear air outlet gear. The openings of the first air door 6 and the second air door 7 are controlled to realize separate adjustment of the air volume of different air outlets in the rear row of the vehicle, and at the same time, ensure that the air volume of the first air outlet 1 and the second air outlet 2 meets the air outlet gear set by the user.

[0054] Therefore, in the present application, the working state of the second blower 5 is controlled according to the size relationship between the front air outlet gear and the rear air outlet gear. When it is determined that the air volume provided by the first blower 4 to different rear air outlets cannot meet the rear air outlet gear set by the user, the air volume of different rear air outlets is compensated by the second blower 5, thereby avoiding the problem of insufficient air volume at different rear air outlets at the rear air outlet gear. On the basis of the air volume provided at the front air outlet gear, the opening of the first air gate 6 and the second air gate 7 are respectively controlled according to the first rear air outlet gear and the second rear air outlet gear, so as to realize the separate adjustment of the air volume of different rear air outlets of the vehicle, and at the same time, ensure that the air volume of the first air outlet 1 and the second air outlet 2 meets the air outlet gear set by the user.

[0055] In some embodiments, a damper is provided corresponding to each rear air outlet, and when the front air outlet gear is not 0 and any of the rear air outlet gears is higher than or equal to the front air outlet gear, the second blower is controlled to start, including: when the front air outlet gear is not 0 and any of the rear air outlet gears is higher than or equal to the front air outlet gear, the highest air outlet gear among the rear air outlet gears is determined, the second blower is controlled to start, and the speed of the second blower is controlled according to the front air outlet gear and the highest air outlet gear; wherein, when there are other air outlet gears lower than any gear except any gear, the damper opening corresponding to the highest air outlet gear is controlled to be fully opened according to the highest air outlet gear, and the opening of the dampers corresponding to other air outlet gears is controlled to be less than the maximum opening, or, when all rear air outlet gears are equal, the opening of each damper is controlled to be fully opened.

[0056] Specifically, when the front air outlet gear is not 0, and there is any gear among the rear air outlet gears that is higher than or equal to the front air outlet gear, it means that the air volume provided by the first blower 4 can only meet the front air outlet gear set for the front air outlet 3, but cannot meet the rear air outlet gears set for multiple rear air outlets 14, and the highest air outlet gear among the rear air outlets 14 is determined, the second blower is controlled to start, and the speed of the second blower is controlled according to the front air outlet gear and the highest air outlet gear, that is, the speed of the second blower 5 is controlled according to the difference between the required air volume corresponding to the highest air outlet gear and the lost air volume provided by the front air outlet gear, so that the first blower 5 can meet the rear air outlet gear set for the front air outlet 3. The compensating air volume provided by the second blower 5 satisfies the highest air outlet gear. When there is an air outlet gear other than any gear that is lower than any gear, the damper opening corresponding to the highest air outlet gear is controlled to be fully open according to the highest air outlet gear to satisfy the air outlet volume of the rear air outlet 14 corresponding to the highest air outlet gear, and the damper openings corresponding to other air outlet gears are controlled to be less than the maximum opening to reduce the air outlet volume of the rear air outlet corresponding to other air outlet gears to satisfy the air outlet gears of other rear air outlets, or, when all rear air outlet gears are equal, the opening of each damper is controlled to be fully open so that the air outlet volume of multiple rear air outlets 14 satisfies the rear air outlet gear set by the user.

[0057] Therefore, in the present application, the working state of the second blower 5 is controlled according to the size relationship between the front air outlet gear and the rear air outlet gear. When it is determined that the air volume provided by the first blower 4 to different rear air outlets cannot meet the rear air outlet gear set by the user, the air volume of each rear air outlet 14 is compensated by the second blower 5, thereby avoiding the problem of insufficient air volume at different rear air outlets at the rear air outlet gear. On the basis of the air volume provided at the front air outlet gear, the opening of the corresponding air door of each rear air outlet 14 is controlled according to the rear air outlet gear, so as to realize the individual adjustment of the air volume of different rear air outlets of the vehicle, and at the same time, ensure that the air volume of each rear air outlet 14 meets the rear air outlet gear set by the user. In some embodiments, the working state of the second blower 5, the opening of the first damper 6 and the opening of the second damper 7 are controlled according to the front row air outlet gear, the first rear row air outlet gear and the second rear row air outlet gear, including: when the front row air outlet gear is not 0, and any one of the first rear row air outlet gear and the second rear row air outlet gear is equal to or higher than the front row air outlet gear, and the other gear of the first rear row air outlet gear and the second rear row air outlet gear except any one gear is lower than any gear, determine the highest air outlet gear of the first rear row air outlet gear and the second rear row air outlet gear, control the second blower 5 to start and control the speed of the second blower 5 according to the highest air outlet gear, control the damper opening corresponding to the highest air outlet gear to be fully open, and control the damper opening corresponding to the lowest air outlet gear to be reduced according to the lowest air outlet gear. When the front row air flow speed is not 0, and the first rear row air flow speed is equal to the second rear row air flow speed, and the first rear row air flow speed is higher than the front row air flow speed, the second blower 5 is started and the speed of the second blower 5 is controlled according to the first rear row air flow speed or the second rear row air flow speed, and the opening of the first damper 6 and the opening of the second damper 7 are both controlled to be fully open.

[0058] Specifically, when the front row air outlet gear is not 0, and any one of the first rear row air outlet gear and the second rear row air outlet gear is equal to or higher than the front row air outlet gear, and the other gear of the first rear row air outlet gear and the second rear row air outlet gear except any one gear is lower than any gear, the highest air outlet gear of the first rear row air outlet gear and the second rear row air outlet gear is determined, and the second blower 5 is started and the speed of the second blower 5 is controlled according to the highest air outlet gear, that is, the gear of the second blower 5 is controlled by the difference between the required air volume corresponding to the highest air outlet gear and the lost air volume provided by the front row air outlet gear, so that the compensating air volume provided by the second blower 5 meets the highest air outlet gear of the first rear row air outlet gear and the second rear row air outlet gear, and the damper opening corresponding to the highest air outlet gear is controlled to be fully open, and the damper opening corresponding to the lowest air outlet gear is controlled to be reduced according to the lowest air outlet gear. Small, in order to reduce the air outlet volume corresponding to the lowest air outlet gear to meet the lowest air outlet gear; when the front row air outlet gear is not 0, and the first rear row air outlet gear is equal to the second rear row air outlet gear, and the first rear row air outlet gear is higher than the front row air outlet gear, then it means that the air volume provided by the first blower 4 cannot meet the rear row air outlet gear of the first air outlet 1 and the second air outlet 2, and the air volume of the first air outlet 1 and the second air outlet 2 are equal. At this time, there is no need to change the opening of the first air door 6 or the second air door 7 to change the air outlet volume of the first air outlet 1 and the second air outlet 2. Then, the second blower 5 is controlled to start and the speed of the second blower 5 is controlled according to the first rear row air outlet gear or the second rear row air outlet gear, and the opening of the first air door 6 and the opening of the second air door 7 are controlled to be fully opened, so that the air outlet volume of the first air outlet 1 and the second air outlet 2 meets the rear row air outlet gear set by the user.

[0059] Therefore, in the present application, the working state of the second blower 5 is controlled according to the size relationship between the front air outlet gear and the rear air outlet gear, so that when it is determined that the air volume provided by the first blower 4 to different rear air outlets cannot meet the rear air outlet gear set by the user, the air volume of different rear air outlets is compensated by the second blower 5, so as to avoid the problem of insufficient air volume of different rear air outlets at the rear air outlet gear. On the basis of the air volume provided at the front air outlet gear, the opening of the first air gate 6 and the second air gate 7 are respectively controlled according to the first rear air outlet gear and the second rear air outlet gear, so as to realize the separate adjustment of the air volume of different rear air outlets of the vehicle, and at the same time, ensure that the air volume of the first air outlet 1 and the second air outlet 2 meets the rear air outlet gear set by the user.

[0060] For example, in actual situations, there are multiple gears for the front row air flow gear, the first rear row air flow gear and the first rear row air flow gear, which can be understood in combination with Table 2. The gears are described by defining the relationship between the front row air flow gear and the first rear row air flow gear and the second rear row air flow gear. For example, if the front row air flow gear is one gear greater than the first rear row air flow gear and the second rear row air flow gear, the first rear row air flow gear and the second rear row air flow gear are defined as medium gears, that is, when the second blower 5 is not turned on, only the first blower 4 can meet the air volume requirements of the first air outlet 1 and the second air outlet 2. For example, if the front row air flow gear is 3 gears, and the first rear row air flow gear and the first rear row air flow gear are both 2 gears, then the first rear row air flow gear and the first rear row air flow gear are considered to be medium gears; if the front row air flow gear is two gears or more greater than the first rear row air flow gear and the second rear row air flow gear, the first rear row air flow gear and the second rear row air flow gear are defined as low gears, or the front row air flow gear is lower than the first rear row air flow gear. The first rear row air flow gear and the second rear row air flow gear define the front row air flow gear as a low gear. For example, if the front row air flow gear is 3, the first rear row air flow gear is 2, and the first rear row air flow gear is 1, then the first rear row air flow gear is considered to be a medium gear and the first rear row air flow gear is a low gear. Or, if the front row air flow gear is 1, the first rear row air flow gear and the first rear row air flow gear are both 2, then the front row air flow gear is considered to be a low gear. If the first rear row air flow gear and the second rear row air flow gear are The exhaust air gear is one gear or more higher than the front air gear, that is, the first rear air gear and the second rear air gear are higher than the middle gear, that is, the second blower 5 needs to be turned on to provide air volume compensation for the first air outlet 1 and the second air outlet 2, and the first rear air gear and the second rear air gear are defined as high gears. For example, if the front air gear is 3 gears, the first rear air gear and the first rear air gear are both 3 gears, then the first rear air gear and the first rear air gear are considered to be high gears. Among them, if it is in a low gear, but the first rear air gear and the second rear air gear are different, it is defined as low one and low two gears; if it is in a high gear, but the first rear air gear and the second rear air gear are different, it is defined as high one and high two gears. If the front air gear is 3 gears, the first rear air gear is 4 gears, and the first rear air gear is 3 gears, then the first rear air gear is considered to be high one and the first rear air gear is high two.

Referring to Table 2, when the front row air flow gear is high, and when the first rear row air flow gear is medium, and when the second rear row air flow gear is medium, the second blower 5 is controlled not to start. At this time, since the first rear row air flow gear and the second rear row air flow gear are the same, the opening of the first damper 6 is controlled to be 0, and the opening of the second damper 7 is controlled to be 0; or, when the front row air flow gear is high, and when the first rear row air flow gear is medium, and when the second air outlet 2 is low, the second blower 5 is controlled not to start. At this time, the opening of the first damper 6 is controlled to be 0, and the opening of the second damper 7 is controlled to be the first opening value, so as to reduce the air volume of the second air outlet 2 to a low gear. At this time, the armrest The passive ventilation of the armrest box is turned on; or, when the front row air outlet gear is high, the first rear row air outlet gear is low, and the second rear row air outlet gear is low, the second blower 5 is controlled not to start, and the opening of the first damper 6 and the second damper 7 is controlled to be the first opening value, so as to reduce the air outlet of the second air outlet 2 to a low gear, and the passive ventilation of the armrest box is turned on; or, when the front row air outlet gear is high, and the second rear row air outlet gear is low one, and the second air outlet 2 is low two, the second blower 5 is controlled not to start, the opening of the first damper 6 is controlled to be the second opening value, and the opening of the second damper 7 is controlled to be the third opening value, wherein the third opening value and the second opening value are actually calibrated according to the low two and low one during the experiment, so as to reduce the air outlet of the second air outlet 2 to the low two gear, and reduce the air outlet of the first air outlet 1 to the low one gear, and the passive ventilation of the armrest box is turned on.

[0063] And, when any one of the first rear row air flow gear and the second rear row air flow gear is equal to the front row air flow gear, and the other one of the first rear row air flow gear and the second rear row air flow gear except any one of the gears is lower than the front row air flow gear, the second blower 5 is controlled to start and perform the action according to any gear, and the damper opening corresponding to any gear is controlled to be fully open, and the damper opening corresponding to the other gear is controlled according to the first rear row air flow gear and the first rear row air flow gear. Referring to Table 2, when the front row air flow gear is high, and the first rear row air flow gear is high, and the second rear row air flow gear is medium, the second blower 5 is controlled according to the first rear row air flow gear being a high gear. At this time, the gear of the second blower 5 is controlled according to the difference between the air volume required by the high gear and the air volume after the loss provided by the medium gear to compensate for the gear corresponding to the air volume difference, and the gear of the first rear row air flow gear is controlled. The opening of the first damper 6 corresponding to the first air outlet 1 is fully open, and the opening of the second damper 7 corresponding to the second air outlet 2 is controlled to be a fourth opening value, wherein the fourth opening value is actually calibrated according to the middle gear during the experiment, so as to reduce the air outlet of the second air outlet 2 to the middle gear, and the passive ventilation of the armrest box is turned on; or, when the front air outlet gear is high, the first rear air outlet gear is high, and the second rear air outlet gear is low, the first blower 4 is controlled according to the first air outlet 1 being a high gear, the opening of the first damper 6 corresponding to the first air outlet 1 is controlled to be fully open, and the opening of the second damper 7 corresponding to the second air outlet 2 is controlled to be a fifth opening value, wherein the fifth opening value is actually calibrated according to the low gear during the experiment, so as to reduce the air outlet of the second air outlet 2 to a low gear, and the passive ventilation of the armrest box is turned on.

[0064] And, in the case that any one of the first rear air outlet gear and the second rear air outlet gear is higher than the front air outlet gear, the highest air outlet gear and the lowest air outlet gear of the first rear air outlet gear and the second rear air outlet gear are determined, and the second blower 5 is controlled to start and perform the action according to the highest air outlet gear, and the damper opening corresponding to the highest air outlet gear is controlled to be fully opened, and the damper opening corresponding to the lowest air outlet gear is controlled according to the first rear air outlet gear and the first rear air outlet gear. Referring to Table 2, in the case that the front air outlet gear is low, the first rear air outlet gear is high, and the second rear air outlet gear is high, according to the first rear air outlet gear and the second rear air outlet gear being equal, the second blower 5 is controlled to start according to any gear, and the openings of the first damper 6 and the second damper 7 are controlled to be fully opened, and the passive ventilation of the armrest box is closed at this time; or , when the front air outlet gear is low, and the first rear air outlet gear is high one, and the second rear air outlet gear is high two, if, high one is greater than high two, then the highest air outlet gear is high one, and the lowest air outlet gear is high two. At this time, the second blower 5 is controlled to start and execute the action according to the highest air outlet gear, that is, the gear of the second blower is controlled according to the air volume difference between the air volume provided by high one and the compensation air volume provided by the low gear of the front air outlet. At this time, the compensation gear of the second blower is the first rear air outlet gear - the front air outlet gear + 1 gear, and the damper opening of the first damper 6 corresponding to high one is controlled to be fully open, and the damper opening of the second damper 7 corresponding to high two is controlled to be the sixth opening value, wherein the sixth opening value is actually calibrated according to the high two gear during the experiment to reduce the air outlet volume of the second air outlet 2 to the high two gear, and the passive ventilation of the armrest box is turned on.

[0065] In the embodiment, when the user selects the high air flow gear for the front row, the high air flow gear for the second rear row, and the high air flow gear for the second air outlet 2, or when the user selects the high air flow gear for the front row, the medium air flow gear for the second rear row, and the medium air flow gear for the second air outlet 2, a pop-up window is required to remind the user of the passive ventilation function of the associated armrest box, and the user can only turn it on after clicking "Agree". In some embodiments, when the first rear outlet air flow gear position and the second rear outlet air flow gear position are both 0, the third air door 11 is controlled to be closed.

[0066] Specifically, when the first rear air outlet gear position and the second rear air outlet gear position are both 0, the user requires that no air should flow out of the rear air outlet of the vehicle. Therefore, the third air door 11 is controlled to close to stop delivering the air generated by the first blower 4 to the first air outlet 1 and the second air outlet 2.

[0067] In some embodiments, the vehicle air conditioning system includes a compressor and a fourth air door. When the rear air outlets 14 are closed, the armrest box set temperature given by the user is obtained; the operating frequency of the compressor and the opening of the fourth air door are controlled according to the armrest box set temperature.

[0068] Specifically, under normal circumstances, when the vehicle air-conditioning system is in operation, if the user has requirements for the rear exhaust air volume of the vehicle and also has requirements for the temperature of the armrest box 12, the vehicle air-conditioning system will give priority to the user's demand for the rear exhaust air volume of the vehicle, and the temperature adjustment of the armrest box 12 is passively adjusted. Therefore, the temperature adjustment of the armrest box 12 is related to the rear exhaust air volume of the vehicle. If the user needs to adjust the temperature of the armrest box 12 without restriction, it should be done under special circumstances. For example, when the first air outlet 1 and the second air outlet 2 are closed, there is no interference from the adjustment of the rear exhaust air volume of the vehicle, and the user can adjust the temperature of the armrest box 12 at will; after the user gives the set temperature of the armrest box 12 through the operation interface, the operating frequency of the compressor is controlled to change the outlet temperature of the vehicle air conditioner, and the ventilation volume and ventilation temperature entering the first air duct 8 from the heat exchange air outlet duct are changed by adjusting the fourth damper, so as to adjust the temperature of the armrest box 12 to the set temperature of the armrest box, thereby realizing the adjustment of the temperature of the armrest box.

[0069] In an embodiment, when the user turns on the rear ventilation function, the armrest box temperature is the same as the rear set temperature.

[0070] In some embodiments, the armrest box air outlet control gear given by the user is obtained; when the speed of the second blower 5 has not reached the maximum speed, the working state of the second blower 5, the opening of the first damper 6 and the opening of the second damper 7 are controlled according to the armrest box air outlet control gear.

[0071] Specifically, the armrest box 12 has passive ventilation function and active ventilation function, wherein the air volume of the passive ventilation function cannot be actively controlled by the user, but, under the passive ventilation function, the current armrest box 12 gear will be displayed through the armrest box 12 ventilation control interface, and, under the active ventilation function, for example, if the second blower 5 has not reached the maximum speed, the armrest box air outlet control gear increase button will be displayed in green, and the user increases or decreases the armrest box 12 air outlet control gear by touching the button to increase or decrease the air volume of the armrest box 12. At the same time, the rear face wind volume of the vehicle is kept unchanged, and the opening of the first damper 6 and the second damper 7 is adjusted to be reduced to ensure that the air volume of the first air outlet 1 and the second air outlet 2 remains unchanged; or, if the speed of the second blower 5 has reached the maximum speed, the display device will display the armrest box 12 air outlet control gear increase button in gray, prompting the user that the air volume of the armrest box 12 cannot be increased at this time. In addition, it should be noted that the actual air volume of the armrest box ventilation is the superposition of the active ventilation and passive ventilation volumes.

[0072] In addition, when reducing the ventilation air volume of the armrest box 12, the air-conditioning controller will calculate the compensation gear level required by the second blower when the air volume of the rear air outlet set by the user does not meet the corresponding air volume of the rear row setting gear level. For example, when the gear level of the first blower 4 is 3, the rear row setting gear level of the first air outlet 1 is 2, and the rear row setting gear level of the second air outlet 2 is 2, the compensation gear level of the second blower is 0. At this time, if the actual gear level of the second blower is higher than the compensation gear level provided by the second blower, the actual gear level of the second blower may be the gear level that is changed when the user adjusts the air volume of the armrest box. Then, the button to reduce the air volume of the armrest box will be displayed in green, and the user can touch the button to reduce the air volume level of the armrest box, that is, reduce the air volume inside the armrest box by reducing the speed of the second blower, and at the same time adjust the opening of the first damper 6 and the second damper 7 to keep the air volume on the rear row of the vehicle unchanged. In addition, when the actual gear position of the second blower set by the user is equal to the compensation gear position provided by the second blower, the button for reducing the air volume of the armrest box 12 is displayed in gray, and the air volume of the armrest box 12 cannot be reduced by the user.
