No. 62/004,202, filed May 29, 2014, and which claims the benefit of Japanese Pat. Appl. No. 2014-153937, filed on Jul. 29, 2014. The entire disclosure of each of the above-identified applications, including the specification, drawings, and claims, is incorporated herein by reference in its entirety.

1. Technical Field

The present disclosure relates to a technique of remotely operating an air conditioner installed in a building from a car.

2. Description of the Related Art

The recent advances of communication technologies have enabled a user to remotely operate a home appliance installed in a building from a car (see Japanese Unexamined Patent Application Publication No. 2002-64881). According to Japanese Unexamined Patent Application Publication No. 2002-64881, a user in a car operates a communication terminal to call a home server installed in a user's home. The user then makes a reservation setting for an operation of a home appliance in the home by using the called home server. As a result, the user is able to remotely control the home appliance.

In general, many users each own a plurality of air conditioners. The technique disclosed in Japanese Unexamined Patent Application Publication No. 2002-64881 enables a user to remotely control an air conditioner, but the user is requested to perform various operations to remotely control a single air conditioner. If the user wants to operate a plurality of air conditioners, the user is requested to perform a large amount of operations.

Thus, a non-limiting exemplary embodiment of the present disclosure provides a technique that enables a user to easily and remotely operate a plurality of air conditioners.

In one general aspect, the techniques disclosed here feature a method for controlling a terminal apparatus that includes a display and that is used for an appliance control system for executing, from a car via a network, remote control on an air conditioner installed in a building. The terminal apparatus includes a memory storing setting information specifying a plurality of air conditioners designated as targets of the remote control. The method includes causing a computer of the terminal apparatus to judge, in response to input of status information indicating that a certain period has not elapsed since power-on of the car, by using the setting information, whether or not there exists an air conditioner designated as a target of the remote control; causing the computer to, in a case where there exist at least two or more air conditioners designated as targets of the remote control, obtain first position information indicating a current position of the car and second position information indicating a position of the building, and judge whether or not the position indicated by the first position information is within a certain region relative to the position indicated by the second position information; causing the computer to, in a case where the position indicated by the first position information is within the certain region relative to the position indicated by the second position information, output, via the display of the terminal apparatus, one common piece of display data prompting a certain remote operation for the at least two or more air conditioners, the one common piece of display data including one common instruction portion for starting the certain remote operation; and causing the computer to, in a case where selection of the one common instruction portion is detected, output control data for executing the certain remote operation on the at least two or more air conditioners to the network, and individually output, via an output unit of the terminal apparatus, for the at least two or more air conditioners, pieces of notification data indicating that the control data has been output for each of the at least two or more air conditioners.

These general and specific aspects may be implemented using a system, a method, and a computer program, and any combination of systems, methods, and computer programs.

The present disclosure enables a user to easily and remotely operate a plurality of air conditioners.

Hereinafter, a description will be given of various embodiments regarding a technique of remotely operating an air conditioner installed in a building from a car, with reference to the attached drawings. The technique of remotely operating an air conditioner installed in a building from a car is clearly understandable from the following description.

Issues Found Out by Inventors

The inventors have studied the technique disclosed in the above-mentioned Japanese Unexamined Patent Application Publication No, 2002-64881, and found out issues involved in the technique disclosed in Japanese Unexamined Patent Application Publication No. 2002-64881. The issues involved in the technique disclosed in Japanese Unexamined Patent Application Publication No. 2002-64881 will be described below.

According to Japanese Unexamined Patent Application Publication No. 2002-64881, a user (for example, a driver) operates a communication terminal in a car to access a home server. The user then makes a reservation setting for a home appliance via the home server.

When a time specified by the reservation setting approaches, the home server transmits confirmation image data to the communication terminal. The confirmation image data is used to determine whether or not the user allows the target home appliance to execute an operation specified by the reservation setting. If the user approves the execution of the operation, a permission signal of permitting the operation of the target home appliance is transmitted from the communication terminal to the home server. In response to the permission signal, the home server generates a control signal for executing the operation specified by the reservation setting. The control signal is transmitted from the home server to the target home appliance.

When the home appliance appropriately receives the control signal, the home appliance generates a notification signal indicating that the home appliance is appropriately operating in accordance with the control signal. The notification signal is transmitted from the home appliance to the home server. The home server transfers the notification signal to the communication terminal.

The technique disclosed in Japanese Unexamined Patent Application Publication No. 2002-64881 is also available for remotely operating a plurality of air conditioners. For example, a user is able to remotely operate a first air conditioner and a second air conditioner, which adjusts the temperature of a room different from a room where the temperature is adjusted by the first air conditioner.

The user is able to set a first time as a preset time for the first air conditioner. The user is able to set a second time, which is different from the first time, as a preset time for the second air conditioner.

When the first time approaches, the home server transmits confirmation image data to the communication terminal. The confirmation image data is used to determine whether or not the user allows the first air conditioner to execute an operation specified by a reservation setting. When the second time approaches, the home server transmits confirmation image data to the communication terminal. The confirmation image data is used to determine whether or not the user allows the second air conditioner to execute an operation specified by a reservation setting. Thus, the user needs to operate the communication terminal every time confirmation image data is transmitted.

Many users do not want to frequently operate a communication terminal in a car. The users may want to finish an operation on the communication terminal in a short time while the car is stopped at a red light. The technique disclosed in Japanese Unexamined Patent Application Publication No. 2002-64881 does not satisfy such users' needs.

On the basis of the above-described considerations, the inventors have conceived of individual aspects of the present disclosure.

An aspect of the present disclosure is a method for controlling a terminal apparatus that includes a display and that is used for an appliance control system for executing, from a car via a network, remote control on an air conditioner installed in a building. The terminal apparatus includes a memory storing setting information specifying a plurality of air conditioners designated as targets of the remote control. The method includes causing a computer of the terminal apparatus to judge, in response to input of status information indicating that a certain period has not elapsed since power-on of the car, by using the setting information, whether or not there exists an air conditioner designated as a target of the remote control; causing the computer to, in a case where there exist at least two or more air conditioners designated as targets of the remote control, obtain first position information indicating a current position of the car and second position information indicating a position of the building, and judge whether or not the position indicated by the first position information is within a certain region relative to the position indicated by the second position information; causing the computer to, in a case where the position indicated by the first position information is within the certain region relative to the position indicated by the second position information, output, via the display of the terminal apparatus, one common piece of display data prompting a certain remote operation for the at least two or more air conditioners, the one common piece of display data including one common instruction portion for starting the certain remote operation; and causing the computer to, in a case where selection of the one common instruction portion is detected, output control data for executing the certain remote operation on the at least two or more air conditioners to the network, and individually output, via an output unit of the terminal apparatus, for the at least two or more air conditioners, pieces of notification data indicating that the control data has been output for each of the at least two or more air conditioners.

According to this aspect, even in the case of starting a remote operation for a plurality of air conditioners, only one common piece of display data is output to the display of the terminal apparatus. A user is able to provide an instruction to execute a remote operation on the plurality of air conditioners only by selecting the one common instruction portion included in the one common piece of display data. In other words, the user only has to perform one input operation and does not need to perform input operations many times while driving, and thus the degree of safety increases.

Further, after the instruction to execute a remote operation on the plurality of air conditioners has been provided, notifications are individually output for the plurality of air conditioners. That is, operations for the plurality of air conditioners are simultaneously executed, and thus the user is correctly notified which air conditioner normally operates and which air conditioner does not normally operate.

In an aspect of the present disclosure, the method further includes causing the computer to, in a case where selection of the one common instruction portion is not detected within a certain period from when the one common piece of display data is output, stop detecting selection of the one common instruction portion and start a re-notification timer, and prevent the one common piece of display data from being output again before a timeout of the re-notification timer occurs.

According to this aspect, in a case where the car is moving in a certain region, for example, sequential output of the same pieces of display data is prevented. Accordingly, output of common display data is appropriately controlled, and efficient control can be executed.

In an aspect of the present disclosure, the method further includes causing the computer to obtain operation statuses from the at least two or more air conditioners after the control data for executing the certain remote operation on the at least two or more air conditioners has been output to the network, and individually output, via the output unit of the terminal apparatus, the operation statuses for the at least two or more air conditioners.

In an aspect of the present disclosure, the setting information includes in advance a fixed order for the plurality of air conditioners, and the method further includes causing the computer to output the pieces of notification data for the at least two or more air conditioners in accordance with the fixed order.

An aspect of the present disclosure is a non-transitory computer readable recording medium storing a program executed by a terminal apparatus that includes a display and that is used for an appliance control system for executing, from a car via a network, remote control on an air conditioner installed in a building. The terminal apparatus includes a memory storing setting information specifying a plurality of air conditioners designated as targets of the remote control. The program causes a computer of the terminal apparatus to judge, in response to input of status information indicating that a certain period has not elapsed since power-on of the car, by using the setting information, whether or not there exists an air conditioner designated as a target of the remote control; in a case where there exist at least two or more air conditioners designated as targets of the remote control, obtain first position information indicating a current position of the car and second position information indicating a position of the building, and judge whether or not the position indicated by the first position information is within a certain region relative to the position indicated by the second position information; in a case where the position indicated by the first position information is within the certain region relative to the position indicated by the second position information, output, via the display of the terminal apparatus, one common piece of display data prompting a certain remote operation for the at least two or more air conditioners, the one common piece of display data including one common instruction portion for starting the certain remote operation; and in a case where selection of the one common instruction portion is detected, output control data for executing the certain remote operation on the at least two or more air conditioners to the network, and individually output, via an output unit of the terminal apparatus, for the at least two or more air conditioners, pieces of notification data indicating that the control data has been output for each of the at least two or more air conditioners.

An aspect of the present disclosure is a recommend method in an appliance control system for executing, from a car via a network, remote control on an air conditioner installed in a building. The recommend method includes judging, in response to input of status information indicating that a certain period has not elapsed since power-on of the car, by using a first memory storing setting information specifying a plurality of air conditioners designated as targets of the remote control, whether or not there exist the plurality of air conditioners designated as targets of the remote control; in a case where there exist at least two or more air conditioners designated as targets of the remote control, obtaining first position information indicating a current position of the car and second position information indicating a position of the building, and judging whether or not the position indicated by the first position information is within a certain region relative to the position indicated by the second position information; in a case where the position indicated by the first position information is within the certain region relative to the position indicated by the second position information, outputting, via a display of the terminal apparatus, one common piece of display data prompting a certain remote operation for the at least two or more air conditioners, the one common piece of display data including one common instruction portion for starting the certain remote operation; and in a case where selection of the one common instruction portion is detected, outputting control data for executing the certain remote operation on the at least two or more air conditioners to the network, and individually outputting, via an output unit of the terminal apparatus, for the at least two or more air conditioners, pieces of notification data indicating that the control data has been output for each of the at least two or more air conditioners.

An aspect of the present disclosure is a terminal apparatus that is used for an appliance control system for executing, from a car via a network, remote control on an air conditioner installed in a building. It is judged, in response to input of status information indicating that a certain period has not elapsed since power-on of the car, by using a first memory storing setting information specifying a plurality of air conditioners designated as targets of the remote control, whether or not there exist the plurality of air conditioners designated as targets of the remote control. In a case where there exist at least two or more air conditioners designated as targets of the remote control, first position information indicating a current position of the car and second position information indicating a position of the building are obtained, and it is judged whether or not the position indicated by the first position information is within a certain region relative to the position indicated by the second position information. In a case where the position indicated by the first position information is within the certain region relative to the position indicated by the second position information, one common piece of display data prompting a certain remote operation for the at least two or more air conditioners is output via a display of the terminal apparatus, the one common piece of display data including one common instruction portion for starting the certain remote operation. In a case where selection of the one common instruction portion is detected, control data for executing the certain remote operation on the at least two or more air conditioners is output to the network, and pieces of notification data indicating that the control data has been output for each of the at least two or more air conditioners are individually output for the at least two or more air conditioners via an output unit of the terminal apparatus.

First Embodiment

As described above, according to the technique disclosed in Japanese Unexamined Patent Application Publication No. 2002-64881, a user is requested to perform frequent operations. In a first embodiment, a description will be given of a technique that allows a user to easily perform remote operations on a plurality of air conditioners.

FIG. 1 is a schematic flowchart illustrating processing executed by a control system that remotely operates, from a car via a network, a plurality of air conditioners installed in a building. With reference to FIG. 1 , a description will be given of the processing executed by the control system. In this embodiment, an appliance control system is exemplified by the control system that executes various processing operations in accordance with the flowchart in FIG. 1 .

The flowchart in FIG. 1 is preferably available for activating a plurality of air conditioners. In the following description, the processing according to the flowchart in FIG. 1 is referred to as “on-recommend processing”. In this embodiment, a recommend method is exemplified by the on-recommend processing described below.

In step S 110 , the control system specifies a plurality of target appliances to be remotely operated. After that, step S 120 is executed.

In step S 120 , the control system specifies a position of a vehicle. If the position of the vehicle satisfies a certain condition, step S 130 is executed.

In step S 130 , the control system presents an operation image to a user. When the user performs a certain operation on the operation image, step S 140 is executed.

In step S 140 , the control system generates control data in response to the operation performed by the user. The control data is output from a communication terminal to a network. In this embodiment, a terminal apparatus is exemplified by the communication terminal. The communication terminal may be an in-vehicle apparatus installed in a vehicle (for example, a car navigation system). Alternatively, the communication terminal may be a mobile terminal carried by the user (for example, a smartphone). Alternatively, the communication terminal may be another apparatus capable of outputting control data from a vehicle to a network. The principle of this embodiment is not limited by a specific communication terminal. After the control data has been output from the communication terminal to the network, step S 150 is executed.

In step S 150 , the control data is output from the network to the plurality of target appliances to be operated. The plurality of target appliances to be operated each generate a notification signal representing the receipt of the control data. The notification signals are output from the individual target appliances to be operated to the communication terminal via the network. In response to the notification signals, the communication terminal generates notification images indicating that the control data has been transmitted to each of the plurality of target appliances to be operated. Accordingly, the user is able to determine whether or not a remote operation has been appropriately executed by seeing the notification images.

FIG. 2 is a conceptual diagram illustrating the processing in step S 110 . With reference to FIGS. 1 and 2 , a description will be given of the processing in step S 110 . In this embodiment, a first judgment step is exemplified by step S 110 .

A memory of the communication terminal stores, in advance, information about a plurality of air conditioners AC 1 , AC 2 , AC 3 , and AC 4 owned by the user. The user presets, in the memory, one or more candidate appliances to be remotely operated using the control system. If the user designates a plurality of air conditioners as candidate appliances to be operated, the processing in step S 110 is continued. FIG. 2 illustrates that the user has set the air conditioners AC 1 , AC 2 , and AC 3 as candidate appliances to be operated. In this embodiment, setting information is exemplified by information representing the air conditioners AC 1 , AC 2 , and AC 3 that are set as candidate appliances to be operated. The candidate appliances to be operated may be set in accordance with a user's need. Therefore, the principle of this embodiment is not limited by a specific setting of candidate appliances to be operated.

The memory also stores information about temperature conditions that are defined for the individual air conditioners AC 1 , AC 2 , and AC 3 set as candidate appliances to be operated, as well as the information about the candidate appliances to be operated. The temperature conditions define start conditions under which the air conditioners AC 1 , AC 2 , and AC 3 are activated. For example, the user may set a lower-limit temperature of 20° C. and an upper-limit temperature of 30° C. as a temperature condition for the air conditioner AC 1 . The user may set a lower-limit temperature of 22° C. and an upper-limit temperature of 33° C. as a temperature condition for the air conditioner AC 2 . The user may set a lower-limit temperature of 18° C. and an upper-limit temperature of 35° C. as a temperature condition for the air conditioner AC 3 . In this embodiment, condition information is exemplified by the information about temperature conditions.

A computer of the communication terminal (for example, a central processing unit (CPU)) compares an outside temperature with a temperature represented by a temperature condition. The outside temperature may be a temperature outside a vehicle. Alternatively, the outside temperature may be a temperature outside the rooms where the plurality of air conditioners AC 1 , AC 2 , AC 3 , and AC 4 are installed. The principle of this embodiment is not limited by a specific position at which an outside temperature is measured.

FIG. 2 illustrates that the air conditioners AC 1 and AC 2 are selected, by the computer, as target appliances to be operated. If information about an outside temperature obtained by the computer represents 34° C., the computer selects the air conditioners AC 1 and AC 2 as target appliances to be operated. The air conditioners AC 1 and AC 2 operate in a cooling mode under the control executed by the control system. That is, the above-described setting of an upper-limit temperature is used as a start condition of starting operation in the cooling mode.

If information about an outside temperature obtained by the computer represents 18° C., the computer selects the air conditioners AC 1 and AC 2 as target appliances to be operated. The air conditioners AC 1 and AC 2 operate in a heating mode under the control executed by the control system. That is, the above-described setting of a lower-limit temperature is used as a start condition of starting operation in the heating mode. In this embodiment, a set temperature is exemplified by the above-described upper-limit temperature and lower-limit temperature. The upper-limit temperature and lower-limit temperature may be determined according to user's preference.

The notification data is transmitted from the air conditioner AC 1 to the network NTW. When the air conditioner AC 2 receives the control data, the air conditioner AC 2 generates notification data representing the receipt of the control data. The notification data is transmitted from the air conditioner AC 2 to the network NTW. The pieces of notification data transmitted from the air conditioners AC 1 and AC 2 are transferred from the network NTW to the communication terminal 100 .

If the network NTW does not receive notification data from the air conditioner AC 1 , the network NTW may generate notification data indicating that transmission of the control data to the air conditioner AC 1 has failed. If the network NTW does not receive notification data from the air conditioner AC 2 , the network NTW may generate notification data indicating that transmission of the control data to the air conditioner AC 2 has failed. In these cases, notification data indicating that transmission of the control data has failed is transmitted from the network NTW to the communication terminal 100 . Accordingly, the communication terminal 100 is able to grasp a result of the transmission of the control data.

FIG. 6 is a conceptual diagram illustrating the processing in step S 150 . With reference to FIGS. 1, 5, and 6 , a description will be given of the processing in step S 150 . In this embodiment, a second display step is exemplified by step S 150 .

The computer of the communication terminal 100 generates notification images NI 1 and NI 2 in accordance with the pieces of notification data transmitted from the network NTW. The computer of the communication terminal 100 generates the notification image NI 1 representing a result of transmission of the control data to the air conditioner AC 1 in accordance with the notification data corresponding to the air conditioner AC 1 . The computer of the communication terminal 100 generates the notification image NI 2 representing a result of transmission of the control data to the air conditioner AC 2 in accordance with the notification data corresponding to the air conditioner AC 2 .
