Abstract

A navigation device (100) estimates a time when a user utilizing the navigation device (100) comes home, and transmits the estimated expected arrival time to a control device (203) in association with the user identifier of the user. In response to receiving the expected arrival times from a plurality of the navigation devices (100), the control device (203) transmits, to an air conditioner (201), a reservation instruction for setting the room temperature at the home to a predetermined target temperature by the estimated arrival time of the earliest user who is supposed to come home earliest. The air conditioner (201) is turned on in accordance with the transmitted reservation instruction among the users.

the control device, in response to receiving the expected arrival times from a plurality of the navigation devices, transmits, to the air conditioning device, a reservation instruction for setting a room temperature at the home to a predetermined target temperature by an expected arrival time of an earliest user who is supposed to come home earliest among the users;

the air conditioning device is turned on in accordance with the transmitted reservation instruction;

the navigation device causes a display device to display a confirmation screen for allowing the user to choose whether to cancel activation reservation of the air conditioning device, and in response to the user'"'"'s choosing the activation reservation cancellation, cancellation notification is transmitted to the control device; and

in response to receiving the cancellation notification, the control device determines the earliest user from among the users other than the user who cancels the activation reservation.

19. The control method according to claim 18, wherein

when the expected arrival time is changed, the navigation device transmits the changed expected arrival time to the control device in association with the user identifier, and

the control device updates the expected arrival time of the earliest user, using the transmitted changed expected arrival time.

20. The control method according to claim 18, wherein

the control device determines, as the target temperature, an intended temperature set by the earliest user, using management data, in which user identifiers of the users and intended temperatures of the air conditioning device set by the users are associated with each other.

21. The control method according to claim 20, wherein

the management data further includes registered room identifiers for identifying rooms at the home where the users use the air conditioning devices, and

the control device determines the room where the earliest user is supposed to stay, using the management data, and transmits the reservation instruction to the air conditioning device installed in the determined room.

22. The control method according to claim 18, wherein

the control device specifies the room where the earliest user is supposed to stay at the expected arrival time of the earliest user, using behavior pattern data indicating which user stays in which room at the home during each time zone, and transmits the reservation instruction to the air conditioning device installed in the specified room.

23. The control method according to claim 18, wherein

when the reservation instruction is transmitted to the air conditioning device, the control device notifies the navigation device of the earliest user, of setting notification including the expected arrival time of the earliest user and the target temperature.

24. The control method according to claim 18, wherein

when the reservation instruction is transmitted to the air conditioning device, the control device notifies the navigation device of a user other than the earliest user, of setting notification including the expected arrival time of the earliest user and the target temperature.

25. The control method according to claim 18, wherein

the control device monitors an operation state of the air conditioning device, and

when a change in the operation state is detected, the control device transmits state change notification indicating the change to the navigation device.

26. The control method according to claim 18, wherein

after the reservation instruction is transmitted, when a change in the room temperature at the home is detected by a temperature sensor for measuring the room temperature, and an activation time of the air conditioning device is changed by the air conditioning device, the control device transmits, to the navigation device, change notification including the detected temperature, the changed activation time, and the target temperature.

27. The control method according to claim 18, wherein

when the reservation instruction is transmitted, if a temperature difference between the room temperature at the home detected by a temperature sensor for measuring the room temperature, and the target temperature exceeds a predetermined allowable value, the control device notifies the navigation device of disable notification indicating that it is impossible to set the target temperature by the expected arrival time of the earliest user.

28. The control method according to claim 23, wherein

in response to receiving the setting notification, the navigation device causes a display device to display the confirmation screen for allowing the user to choose whether to cancel activation reservation of the air conditioning device.

29. The control method according to claim 25, wherein

in response to receiving the state change notification, the navigation device causes a display device to display a confirmation screen for allowing the user to choose whether to stop activation of the air conditioning device, and in response to the user'"'"'s choosing to stop activation, an activation stop instruction is transmitted to the control device, and

in response to receiving the activation stop instruction, the control device stops activation of the air conditioning device.

30. The control method according to claim 26, wherein

in response to receiving the change notification, the navigation device causes a display device to display the confirmation screen for allowing the user to choose whether to cancel activation reservation of the air conditioning device.

31. The control method according to claim 27, wherein

in response to receiving the disable notification, the navigation device causes a display device to display the confirmation screen for allowing the user to choose whether to cancel activation reservation of the air conditioning device.

32. An air conditioning control system provided with a navigation device which guides a user home, a control device which controls an air conditioning device installed at the home, and the air conditioning device, wherein

the navigation device includes:

an estimation unit which estimates a time when the user utilizing the navigation device comes home; and

a first communication unit which transmits the estimated expected arrival time to the control device in association with a user identifier of the user,

the control device includes;

a second communication unit; and

a setting unit, in response to receiving the expected arrival times from a plurality of the navigation devices by the second communication unit, transmits a reservation instruction to the air conditioning device via the second communication unit, the reservation instruction being an instruction for setting a room temperature at the home to a predetermined target temperature by the expected arrival time of an earliest user who is supposed to come home earliest among the users,

the air conditioning device is turned on in accordance with the transmitted reservation instruction,

the navigation device further includes a display device which displays a confirmation screen for allowing the user to choose whether to cancel activation reservation of the air conditioning device,

in response to the user'"'"'s choosing the activation reservation cancellation, the first communication unit of the navigation device transmits cancellation notification to the control device, and

in response to receiving the cancellation notification, the setting unit of the control device determines the earliest user from among the users other than the user who cancels the activation reservation.

33. A navigation device for use in an air conditioning control system provided with a navigation device which guides a user home, a control device which controls an air conditioning device installed at the home, and the air conditioning device, comprising:
