The operation of each seat air conditioner 50 will be described with reference to FIG. 5 showing the flow of individual air conditioning control processing executed by the seat side control device 70. Each seat-side control device 70 executes the individual air conditioning control process shown in FIG. 5 at a predetermined timing in a state where the start switch of the vehicle MV is turned on. Note that each step shown in FIG. 5 constitutes a function realizing unit that realizes each function by the seat-side control device 70.

  As shown in FIG. 5, in step S <b> 100, the seat side control device 70 reads various signals such as sensor signals and operation signals of the individual side operation unit 71 from various sensors connected to the input side. And the seat side control apparatus 70 acquires the whole side information which the indoor side control apparatus 40 holds from the indoor side control apparatus 40 in step S110. Specifically, the seat-side control device 70 receives the operation state of the indoor air-conditioning device 10 from the indoor-side control device 40, detection signals of various sensors connected to the input side of the indoor air-conditioning device 10, On-off information of the 1-sheet switch 433 is acquired.

  Subsequently, the seat side control device 70 calculates the target outlet temperature TAOs of the seat air conditioner 50 in step S120. The seat-side control device 70 calculates a temporary target temperature based on, for example, the air blowing temperature Tes from the sub-evaporator 53 and the set temperature Tsets set by the temperature setting switch. And the seat side control apparatus 70 calculates the value which correct | amended temporary target temperature with internal temperature Tr and the solar radiation amount Ts as target blowing temperature TAOs.

  Here, at the time of cooling the passenger compartment, the cooling load in the passenger compartment increases when the inside air temperature Tr is higher than the set temperature Tsets or when the solar radiation amount Ts is large. For this reason, when the inside air temperature Tr is higher than the set temperature Tsets or when the solar radiation amount Ts is large during cooling of the vehicle interior, the seat side control device 70 corrects the temporary target temperature so that the target blowing temperature TAOs becomes high. .

  Subsequently, in step S130, the sheet-side control device 70 determines whether any of the sheet switches 433 and 711 is turned on. In the determination processing in step S130, it is determined whether or not a request signal for instructing air conditioning (that is, seat air conditioning) at a specific location in the vehicle interior is received from the outside.

  As a result of the determination process in step S130, when both the sheet switches 433 and 711 are off, the sheet-side control device 70 returns to step S100.

  On the other hand, if any of the seat switches 433 and 711 is turned on as a result of the determination process in step S130, the seat-side control device 70 exhibits the air conditioning capability in step S140 when the operating state of the indoor air conditioner 10 is activated. It is determined whether it is the driving | running state to perform.

  As a result, when the operating state of the indoor air conditioner 10 is the operating state, the seat side control device 70 controls the operation of various devices of the seat air conditioner 50 based on the target blowing temperature TAOs in step S150.

  On the other hand, when the operating state of the indoor air conditioner 10 is a stop state in which the air conditioning function is not exhibited, the seat-side control device 70 enters a stop state in which the operating state of the seat air conditioner 50 does not exhibit the air conditioning capability in step S160. To control.

  Then, in step S170, the seat-side control device 70 indicates an air-conditioning stop state in which the operation state of the seat air-conditioning device 50 is stopped even if any of the seat switches 433 and 711 is turned on. Is output to the indoor control device 40. Thereafter, the seat-side control device 70 returns to step S100.

  Next, the operation of the indoor air conditioner 10 will be described with reference to FIG. 6 showing the flow of the overall air conditioning control process performed by the indoor control device 40. The indoor-side control device 40 executes the overall air conditioning control process shown in FIG. 6 at a predetermined timing in a state where the start switch of the vehicle MV is turned on. In addition, each step shown in FIG. 6 comprises the function implementation part which the indoor side control apparatus 40 implement | achieves each function.

  As shown in FIG. 6, the indoor side control device 40 reads various signals such as a sensor signal and an operation signal of the overall operation unit 43 from various sensors connected to the input side in step S500. And the indoor side control apparatus 40 acquires the individual side information which the sheet | seat side control apparatus 70 holds from the sheet | seat side control apparatus 70 in step S510. Specifically, the indoor-side control device 40 receives the operation state of the seat air-conditioning device 50 from the seat-side control device 70, detection signals of various sensors connected to the input side of the seat air-conditioning device 50, The on / off information of the 2A / C switch 713 is acquired.

  Subsequently, in step S520, the indoor side control device 40 notifies the user of the air conditioning information of the indoor air conditioning device 10 and the seat air conditioning device 50 by the notification device 41.

  Specifically, when the indoor-side control device 40 receives a signal indicating an air-conditioning stop state from the seat-side control device 70, the seat control is performed regardless of which of the seat switches 433 and 711 is on. The user is notified that the air conditioner 50 is stopped. At this time, it is desirable to provide the user with information that prompts the A / C switches 431 and 713 to be turned on.

  Subsequently, in step S530, the indoor side control device 40 determines whether any of the A / C switches 431 and 713 is turned on. In the determination processing in step S530, it is determined whether or not a request signal for instructing air conditioning in the passenger compartment is received from the outside.

  If both the A / C switches 431 and 713 are off as a result of the determination process in step S530, the indoor side control device 40 returns to step S500.

  On the other hand, if any of the A / C switches 431 and 713 is turned on as a result of the determination process in step S530, the indoor control device 40 calculates the target outlet temperature TAOa of the indoor air conditioner 10 in step S540. To do.

  For example, the indoor control device 40 calculates the target blowing temperature TAOa by substituting the set temperature Tset, the internal temperature Tr, the external temperature Tam, and the solar radiation amount Ts set by the temperature setting switch into the following formula F1.

TAOa = Kset × Tset−Kr × Tr−Ktam × Tam−Ks × Ts + C (F1)
Note that Kset, Kr, Ktam, and Ks in Formula F1 described above are control gains. Further, C in the above formula F1 is a correction constant.

  Subsequently, in step S550, the indoor side control device 40 determines whether or not the operating state of the seat air conditioner 50 is an operation state in which the air conditioning capability is exhibited. As a result, when the operating state of the seat air conditioner 50 is the stopped state, the indoor control device 40 controls the operation of various devices of the indoor air conditioner 10 based on the target blowing temperature TAOa in step S560.

  On the other hand, as a result of the determination process in step S550, when the operating state of the seat air conditioner 50 is the operating state, the indoor control device 40 determines in step S570 whether the temperature deviation condition is satisfied.

  This temperature divergence condition is established when the temperature difference between the temperature at a specific location (that is, around the seat) to be air-conditioned by the seat air conditioner 50 and the temperature at a location different from the specific location is a predetermined value or more. It is a condition to do. The temperature deviation condition of the present embodiment is a condition that is satisfied when the temperature around the rear seat RS detected by the infrared sensor 405 is higher than a predetermined value with respect to the temperature around the front seat FS. Note that the temperature divergence condition may be a condition that is satisfied when, for example, a factor that increases the indoor temperature difference based on an experiment or the like is specified in advance and the factor occurs.

  When the temperature around the rear seat RS is higher than the temperature around the front seat FS by a predetermined value or more, it is considered that air conditioning by the indoor air conditioner 10 and the seat air conditioner 50 is excessive.

  For this reason, when the temperature deviation condition is satisfied in the determination process of step S570, the indoor control device 40 calculates a correction coefficient α for reducing the air conditioning capability of the indoor air conditioner 10 in step S580. . The correction coefficient α may be a fixed value, but is preferably a variable value that increases as the temperature difference between the temperature around the rear seat RS and the temperature around the front seat FS increases.

  Subsequently, in step S590, the seat-side control device 70 controls the operation of various devices of the indoor air conditioner 10 based on the value obtained by adding the correction coefficient α to the target blowing temperature TAOa. Thereby, the temperature distribution in the passenger compartment is reduced due to a decrease in the air conditioning capability of the indoor air conditioner 10.

  When the temperature divergence condition is not satisfied in the determination process of step S570, the indoor control device 40 proceeds to step S560 and controls the operation of various devices of the indoor air conditioner 10 based on the target blowing temperature TAOa. To do.

Specifically, the vehicle air conditioning system 1 according to the present embodiment is configured such that the indoor side control device 40 and the seat side control device 70 can communicate with each other by wireless communication. According to this, since the wiring for communication in the passenger compartment is not required, the degree of freedom of arrangement of the indoor air conditioner 10 and the seat air conditioner 50 can be improved.

  Moreover, the vehicle air conditioning system 1 of this embodiment can also acquire the information which one control apparatus acquired among the indoor side control apparatuses 40 and the seat side control apparatuses 70 also in the other control apparatus. Specifically, the seat side control device 70 acquires information on the inside air temperature Tr and the solar radiation amount Ts from the indoor side control device 40, and controls the air conditioning capability of the seat air conditioner 50 using the acquired information.
