FIG. 11 is a block diagram showing the configuration of the server 91 according to this modification. The server 91 of FIG. 11 includes a communication unit 91a and a control unit 91b, and can perform wireless communication with a vehicle device 93 that controls a plurality of display devices, an air conditioner, and the like of the vehicle 92.

The communication unit 91a, which is an acquisition unit, receives the temperature and occupant information of a plurality of display devices in the vehicle interior acquired by the vehicle device 93 by performing wireless communication with the vehicle device 93.

The control unit 91b has the same function as the control unit 12 of FIG. 1 when a processor (not shown) of the server 91 or the like executes a program stored in a memory (not shown) of the server 91. That is, the control unit 91b generates a control signal for performing individual display device control and air conditioning device control based on the temperature and occupant information of the plurality of display devices in the vehicle interior received by the communication unit 91a. The communication unit 91a transmits the control signal generated by the control unit 91b to the vehicle device 93. According to the server 91 configured in this way, the same effect as that of the air conditioning control device 1 described in the first embodiment can be obtained.

FIG. 12 is a block diagram showing the configuration of the communication terminal 96 according to this modification. The communication terminal 96 of FIG. 12 includes a communication unit 96a similar to the communication unit 91a and a control unit 96b similar to the control unit 91b, and can perform wireless communication with the vehicle device 98 of the vehicle 97. ing. The communication terminal 96 is, for example, a mobile terminal such as a mobile phone, a smartphone, or a tablet carried by the driver of the vehicle 97. According to the communication terminal 96 configured in this way, the same effect as that of the air conditioning control device 1 described in the first embodiment can be obtained.

It is possible to freely combine each embodiment and each modification, and appropriately modify or omit each embodiment and each modification.

The above explanation is an example, not a limitation, in all aspects. A myriad of variants not illustrated are understood to be conceivable.
