S22: when heating or ventilating the seat in the vehicle, the air quantity of the blower of the air conditioner in the vehicle is reduced.
After determining to heat or ventilate the seats in the vehicle according to the parameters monitored by the air conditioner in the vehicle, the seat controller 19 controls the seat heating device 18 or the seat ventilation device 19 to work; when heating or ventilating the seats in the vehicle, the air quantity of the blower 16 of the air conditioner in the vehicle is reduced under the condition of meeting the comfort level of the air in the vehicle, so that the energy consumption of the air conditioning system in the vehicle is saved.

The automatic control scheme provided by the invention can perform different control according to two different conditions of the opening of the air conditioner and the non-opening of the air conditioner.
In the case that the air conditioner in the vehicle is on and the manual mode of the seat is not on, the executing step S11 specifically includes:
step 111: calculating target temperature T of air outlet of air conditioner in vehicle gvent And the actual temperature T of the air outlet vent Is a difference DeltaT between (1) vent ，△T vent ＝T gvent -T vent 。
Step 112: calculating target evaporator temperature T of air conditioner in vehicle ge And the actual temperature T of the evaporator e Is a difference DeltaT between (1) e ，△T e ＝T ge -T e 。

In one embodiment, when DeltaT vent ≥T vent1 And DeltaT e ≥T e1 And when the temperature is high, the heating of the seat in the vehicle is determined, otherwise, the heating of the seat in the vehicle is not determined. For a seat having a heating level, a process of determining the heating level is also included when determining to heat the seat in the vehicle.
The heating grade determining process comprises the steps of determining heating parameters according to a heating parameter formula; and determining the heating grade according to the range of the heating parameter. The heating parameter formula is:
R HL ＝S×((f Tam2 -T am )+(I/f I2 ))×(f Tin2 -T in )
wherein R is HL S is a correction parameter, S is more than 0, T am F is the actual temperature outside the vehicle Tam2 For the second outside temperature threshold, I is the sunlight intensity, f I2 For a second sunlight intensity threshold, T in F is the actual temperature in the vehicle Tin2 A second in-vehicle temperature threshold. f (f) Tam2 、f I2 And f Tin2 All are calibration constants, f is more than or equal to 5 Tam2 ≤10；5≤f Tin2 ≤10，50≤f I2 ≤100。
For the seat with the heating grade, the air quantity of the blower of the air conditioner in the vehicle can be reduced differently according to different heating grades.
For a seating system with three-stage seat ventilation, R will be HL Value and preset R HL1 、R HL2 、R HL3 Comparing, and performing heat grade pre-judgment, wherein the pre-judgment conditions are as follows:
conditions (conditions) Heating gear H
R HL1 ≥R HL 0
R HL2 ≥R HL ≥R HL1 1
R HL3 ≥R HL ≥R HL2 2
R HL ≥R HL3 3
R HL3 ≥R HL2 ≥R HL1 And is more than or equal to 0. The more the value of the heating gear HA large heating level indicates a higher heating effect. A heating range H of 0 indicates that no heating is performed. When the seat in the vehicle is heated, the air volume Ga of the blower of the air conditioner in the vehicle is adjusted according to the formula ga=k1×ga. k1 is a calibration parameter associated with a heating range H, the relationship between which is shown in the following table.
Step 114: according to DeltaT vent And a second temperature difference threshold T vent2 Is a function of the magnitude of DeltaT e And a fourth temperature difference threshold T e2 And judging whether to ventilate the seats in the vehicle.

In one embodiment, when DeltaT vent ≤T vent2 And DeltaT e ≤T e2 When the vehicle seat is large, the ventilation of the vehicle seat is determined, otherwise, the ventilation of the vehicle seat is not determined. For seats having ventilation levels, the process of determining the ventilation level is also included when determining ventilation to the seat in the vehicle.
The ventilation grade is determined by determining ventilation parameters according to a ventilation parameter formula; and determining the ventilation level according to the range of the ventilation parameters. The ventilation parameter formula is specifically as follows:
R VL ＝K×((T am -f Tam1 )+(I/f I1 ))×(T in -f Tin1 )
wherein R is VL Is ventilation parameter, K is correction parameter, K is greater than 0, T am F is the actual temperature outside the vehicle Tam1 Is a first vehicle exterior temperature threshold, I is sunlight intensity, f I1 For a first sunlight intensity threshold, T in F is the actual temperature in the vehicle Tin1 A first in-vehicle temperature threshold. f (f) Tam1 、f I1 And f Tin1 All are calibration constants. F is not less than 5 Tam1 ≤10；5≤f Tin1 ≤10，50≤f I1 ≤100。
For the seats with ventilation grades, different air volumes of the blowers of the air conditioner in the vehicle are reduced according to different ventilation grades.
For a seating system with three-stage seat ventilation, R will be VL Value and preset R VL1 、R VL2 、R VL3 Comparing, and pre-judging the ventilation grade, wherein the judging conditions are as follows:
conditions (conditions) Ventilation gear D
R VL1 ≥R VL 0
R VL2 ≥R VL ≥ RVL1 1
R VL3 ≥R VL ≥R VL2 2
R VL ≥R VL3 3
R VL3 ≥R VL2 ≥R VL1 And is more than or equal to 0. The larger the value of the ventilation gear D is, the higher the ventilation grade is, and the better the ventilation effect is; a ventilation gear D of 0 indicates that no ventilation is performed. When ventilation is performed on the seat in the vehicle, the vehicle is ventilated according to the formula ga=f×gaThe air volume Ga of the blower of the air conditioner in the vehicle is adjusted. f is a calibration parameter associated with a ventilation gear D. The relationship between the two is shown in the following table
In the control process, along with the actual temperature T outside the vehicle am Actual temperature T in the vehicle am And the change of parameters such as sunlight intensity I and the like, R VL And R is HL The values will vary so that the ventilation level and the heating level of the seats in the vehicle will also vary. The control of the vehicle seat and the vehicle air conditioner is coordinated.
In the case where the in-vehicle air conditioner is not turned on and the manual mode of the seat is not turned on, the performing step S11 specifically includes: according to the temperature range of the actual temperature outside the vehicle and the temperature range of the actual temperature inside the vehicle, whether the seat inside the vehicle is heated or not is judged, and whether the seat inside the vehicle is ventilated or not is judged.
For the vehicle seat with the heating level, when the heating of the vehicle seat is determined, the specific heating level is also determined according to the temperature range in which the actual temperature outside the vehicle is located and the temperature range in which the actual temperature inside the vehicle is located. And reducing the heating level after the duration of the sunlight intensity greater than the sunlight intensity threshold is greater than the duration threshold while heating the seat within the vehicle.

3、0℃＜T in less than or equal to 10 ℃ and T am And when the temperature is less than 10 ℃, the heating of the H=1 grade seat is started.

I≥I3 t≥t1 H-3
When the condition 1 and the condition 2 are satisfied simultaneously, the output value is the adjusted heating gear value, and when the output value is smaller than 0, the output value is 0.
For the vehicle seat with the ventilation level, when the ventilation of the vehicle seat is determined, the specific ventilation level is determined according to the temperature range of the actual temperature outside the vehicle and the temperature range of the actual temperature inside the vehicle. And increasing the heating level after the duration of the sunlight intensity greater than the sunlight intensity threshold is greater than the duration threshold while ventilating the seat in the vehicle.
For a seat system with three-stage seat ventilation when ventilation is performed on a seat in a vehicle, the ventilation is performed according to the actual temperature T in the vehicle in And the actual temperature T outside the vehicle am Determining a specific ventilation level:
