  As an example of a method for suppressing the increase in energy consumed by the air conditioner, if the cooling or heating by the air conditioner is excessive, that is, if it is determined that the air conditioner is operating excessively, the operation of the air conditioner is stopped. It is possible to suppress and reduce energy consumption. For example, in Patent Document 1, in an air conditioning control system for a vehicle, when it is expected that a required time to a destination, that is, a remaining time to use air conditioning is expected to be short, it is switched to an energy saving mode in which an operating rate of an air conditioner is small. This suppresses the air conditioner from operating excessively and suppresses the amount of energy consumed.

  However, in Patent Document 1, only the excessive operation is suppressed in the situation where the destination is set and the time required to reach the destination is expected to be short, and the excessive operation of the air conditioner is widely suppressed in other situations. I couldn't.

  The present invention has been made based on this situation, and an object thereof is to reduce the energy consumption by changing the operating state of the air conditioner according to the situation where the vehicle equipped with the air conditioner is placed. An object of the present invention is to provide an air conditioning control system that can be set to a different operating state.

  The above objective is achieved by a combination of features described in independent claims, and the subclaims define further advantageous embodiments of the invention. The reference numerals in parentheses in the claims indicate the correspondence with the specific means described in the embodiments described later as one aspect, and do not limit the technical scope of the present invention. .

Changes the operating state of the target air conditioner to the operating state indicated by the operating state of the other vehicle when the energy consumption of the operating state of the target air conditioner is larger than the energy consumption of the operating state of the other vehicle. To.

  According to the above configuration, the other vehicle operation extraction unit, based on the statistical data indicating the operation state of the other vehicle air conditioner in the situation similar to the target vehicle situation, determines the average operation state of the other vehicle in the similar situation. Extract as a state. The operation control unit changes the operating state of the target air conditioner to the operating state indicated by the operating state of the other vehicle when the other vehicle operating state consumes less energy than the operating state of the target air conditioner.

  As a result, when it is estimated that the energy consumption of the operating state of the target air conditioner is higher than the average operating state in a similar situation to the target vehicle situation, the operating state of the target air conditioner is changed to that average operating state. Let That is, in a situation where the energy consumption is higher than the average operating state of other vehicles and it is estimated that the air conditioning system is operating excessively, the energy consumption of the air conditioning system is automatically changed to the reduced operating state.

<Embodiment>
An air conditioning control system 1 as an embodiment of the present invention will be described below with reference to the drawings. The air conditioning control system 1 is a control system for controlling the operating state so that the amount of energy consumed by the target air conditioner of the target vehicle to be controlled is suppressed. Specifically, it is determined that the target air conditioner is operating excessively based on the average operating state of the other vehicle air conditioners used in other vehicles other than the target vehicle. If the target air conditioner operates, the operation of the target air conditioner is suppressed.

  However, the operating state is an air conditioner that can compare the energy consumed when operating in one operating state with the energy consumed when operating in another operating state. Indicates the state of the device. For example, the rotation speeds of the blower and the compressor included in the air conditioner, the target temperature of the temperature of the air that has passed through the evaporator, or a combination thereof may be set as the operating state controlled by the air conditioning control system 1.

  Note that the smaller the rotation speed of the blower or compressor, the smaller the energy consumption, and the smaller the target temperature of the air that has passed through the evaporator, the higher the rotation speed of the compressor or the proportion of the operating time. Grows larger. Further, the state of the air conditioner indicated by the operating state is not limited to this example, and may be appropriately determined according to the configuration of the air conditioner. For example, when it is difficult to control the rotation speed because the compressor is driven by the engine, the ratio of the time the compressor is operating to the time it is stopped may be earned. Alternatively, the target temperature of the blown air may be indicated.

  Before entering the configuration and detailed description of the air conditioning control system 1, an outline of the operation of the air conditioning control system 1 will be described with reference to FIG. The air conditioning control system 1 includes an air conditioner 100a and a mobile terminal 200a used in the vehicle 10a, an air conditioner 100b and a mobile terminal 200b used in the vehicle 10b, and a data management device 300 used in the data center 30.

  However, in the present embodiment, the air conditioner 100a and the air conditioner 100b have the same configuration, and the mobile terminal 200a and the mobile terminal 200b have the same configuration. Hereinafter, when the vehicle 10a and the vehicle 10b are not distinguished from each other, they are collectively referred to as the vehicle 10, and when the air conditioner 100a and the air conditioner 100b are not distinguished from each other, they are collectively referred to as the air conditioner 100. Further, when the mobile terminal 200a and the mobile terminal 200b are not distinguished, they are collectively referred to as the mobile terminal 200.

  Note that, in addition to the two units, an air conditioner 100 and a mobile terminal 200 having the same configuration are actually used, and there is a vehicle 10 whose operation is similarly controlled by the air conditioning control system 1. . However, in the following description of the present embodiment, the air conditioning control system 1 will be described focusing on the operation of the two vehicles 10 shown in FIG. 1.

  Specifically, assuming that the vehicle 10a corresponds to the target vehicle of the claims, the mobile terminal 200a corresponds to the target mobile terminal of the claims, and the air conditioner 100a corresponds to the target air conditioner of the claims, the operating state of the air conditioner 100a is determined. The case of controlling will be described. At this time, the vehicle 10 other than the vehicle 10a corresponds to the other vehicle in the claims, so the vehicle 10b is an example of the other vehicle. Accordingly, the air conditioner 100b used in the vehicle 10b corresponds to the other vehicle air conditioner, and the mobile terminal 200b corresponds to the other vehicle terminal.

  However, the air conditioner 100a and the air conditioner 100b have the same configuration, and the mobile terminal 200a and the mobile terminal 200b have the same configuration. Therefore, the vehicle 10b can also perform an operation corresponding to the claimed subject vehicle, and the vehicle 10a can also perform an operation as another vehicle. That is, the operation of the vehicle 10a and the operation of the vehicle 10b may be interchanged.

  The air conditioner 100 is a device that performs air conditioning in the vehicle interior of the vehicle 10, performs wireless communication with the mobile terminal 200, periodically transmits the operating state to the mobile terminal 200, and is transmitted from the mobile terminal 200. It operates in the operating state indicated by the control signal described later.

  The mobile terminal 200 is a device that performs wireless communication with the base station 2 and also communicates with the data management device 300 via the base station 2 and the public line network 3, and for example, a smartphone or a tablet terminal can be used. it can.

  The public line network 3 is, for example, a mobile phone network or the Internet. The base station 2 is a wireless base station for connecting a device having a wireless communication function such as the mobile terminal 200 to the public line network 3. However, although only one base station 2 is illustrated, a plurality of base stations 2 actually exist, and for example, the base station 2 with which the mobile terminal 200a communicates and the base station 2 with which the mobile terminal 200b communicates are different. Good.

  The mobile terminal 200b transmits, to the data management device 300, an operation record in which the operation state transmitted from the air conditioner 100b is associated with the other vehicle situation where the vehicle 10b is placed. In addition, the transmission of the operation record may be collectively performed at a predetermined cycle.

  The mobile terminal 200a acquires operation statistical data by communicating with the data management device 300. Based on this operation statistical data and the target vehicle status, which is the status where the vehicle 10a is placed, an average operating status in a status similar to the target vehicle status is extracted as another vehicle operating status. However, the average operating state means a normal operating state that is not exceptional, and it is not always necessary to use the average value to determine. For example, the median value or the mode value may be used for the determination. In addition, when the mobile terminal 200a determines that the energy consumption of the operating state of the air conditioner 100a is greater than the extracted operating state of the other vehicle, the portable terminal 200a transmits the other vehicle operating state to the air conditioner 100a, and the other vehicle operating state indicates. Change to operating status.

  The data management device 300 receives operation records from the mobile terminals 200 used in each of the plurality of vehicles 10, classifies the operation states included in the operation records according to the vehicle conditions included in those operation records, and generates operation statistical data. The data management device 300 can be realized using, for example, one or a plurality of server devices.

  The content of the operation statistical data of the present embodiment is that each set of vehicle situations in which the vehicle situations are classified is associated with tendency data indicating the tendency of the operating state in the vehicle situations included in the set.

  The set of vehicle conditions is determined by classifying the vehicle conditions into similar sets of vehicle conditions according to region, season, time of day, and weather. Regions may be classified, for example, by municipalities or by 1 km square. The season and time zone may be divided, for example, every month and every two hours. The weather may be classified into fine weather, cloudy weather, and rain. Therefore, an example of a set of vehicle situations into which the vehicle situations are classified is, for example, a clear 18:00 to 20:00 in August in a certain city.

  The tendency data is data that can determine an average operating state, which indicates the tendency of the operating state corresponding to the vehicle states classified into the set of vehicle states for each set of vehicle states. For example, if the number of revolutions of the compressor is used as the operating state, the distribution of the frequency of each number of revolutions included in the operation record itself or a statistical value indicating the average operating state extracted from the distribution, for example, the average of the number of revolutions Values, median, mode, etc. can be used. In the present embodiment, the average value of the number of revolutions of the compressor will be described as an example of the tendency data.

  Therefore, as an example of the contents of such operation statistical data, the average value of the number of revolutions of the compressor is per minute for a set of vehicle conditions in a certain city in August, which is sunny from 18:00 to 20:00. The tendency of the operating condition of the other vehicle air conditioner, such as 4000 rpm, is associated.

  The air conditioning control system 1 uses such operation statistical data to extract an average operating state in a situation similar to the state in which the vehicle 10 is placed as another vehicle operating state. When the energy consumption of the operating state of the target air conditioner is larger than that of the operating state of the other vehicle, it is determined that the operating state of the target air conditioning system is the operating state that consumes excessive energy, and the operating state of the other vehicle is Control to the operating state shown.

  In addition, in the present embodiment, the operation statistical data is distributed to the mobile terminal 200 at a predetermined distribution cycle such as every one week or every one month, and the operation statistical data most recently distributed until the new distribution. It is held and control is performed using the held operation statistical data. Therefore, it is not necessary to sequentially perform communication in order to acquire the operation statistical data used for control, and thus it is possible to suppress the communication cost.

[Configuration of air conditioner 100]
The configuration of the air conditioner 100 will be described with reference to FIG. The air conditioner 100 includes a short-range communication unit 101, an air conditioning function unit 102, a temperature setting unit 103, and a control unit 110. The short-range communication unit 101 is a communication device for wirelessly communicating with the mobile terminal 200 used in the vehicle 10 that uses the air conditioner 100, and is portable according to a short-range wireless communication standard such as Wi-Fi (registered trademark). Communication with the terminal 200 may be performed.

  The air conditioning functional unit 102 is composed of various air conditioning functional components for realizing air conditioning in the vehicle interior. For example, the air conditioning function unit 102 includes an inside / outside air switching door for switching between inside and outside air, a blower for blowing air, a refrigeration cycle unit configured to cool air including a compressor and an evaporator, a heater core for heating air, and the like. Composed. That is, the operating state of the air conditioner 100 indicates the operating state of various air conditioning functional parts included in the air conditioning functional unit 102.

  The temperature setting unit 103 is an input device for the user to set the target temperature of the air temperature in the vehicle interior, and for example, a slide switch may be used to set the temperature according to the switch position as the target temperature.

  The control unit 110, and a control unit 205 and a control unit 310, which will be described later, respectively included in the mobile terminal 200 and the data management device 300 are configured as a computer including a CPU, a ROM, a RAM, and the like. These control units are predetermined by the CPU executing a program stored in a non-transitory tangible storage medium while using the temporary storage function of the RAM. Exert function. The non-transitional physical storage medium may be realized by using a semiconductor storage device such as ROM or RAM or a magnetic storage medium such as a magnetic disk. It should be noted that some or all of the functions exhibited by these control units may be implemented by hardware by one or more ICs or the like. The control unit 110 exerts the functions of the operation determination unit 111, the operation transmission unit 112, and the operation control unit 113.

  The operation determining unit 111 determines the operation state of the air conditioner 100 when the other vehicle operation state is not received as the normal operation state. In the normal operating state, the outside air temperature, the inside air temperature and the amount of solar radiation acquired by the outside air temperature sensor 11, the inside air temperature sensor 12, and the solar radiation sensor 13 provided in the vehicle 10, and the user operating the temperature setting unit 103. It is determined based on the target temperature set by the above.

  Specifically, first, a target blowout temperature, which is a target temperature of air blown into the vehicle interior, is calculated. The target outlet temperature is calculated by substituting the air temperature, the amount of solar radiation, and the target temperature outside and inside the vehicle into a predetermined relational expression for calculating the target outlet temperature from the temperature, the amount of solar radiation, and the target temperature. To do. Next, the operating state for achieving the calculated target outlet temperature is determined as the normal operating state based on the previously determined relation between the operating state and the temperature of the air blown into the vehicle interior.

  The operation transmission unit 112 causes the short-range communication unit 101 to transmit the normal operation state determined by the operation control unit 113 to the mobile terminal 200. The operation control unit 113 controls various air conditioning functional components that configure the air conditioning functional unit 102 so that the normal operating state determined by the operation determining unit 111 is in the operating state.

  However, when the short-range communication unit 101 receives the other vehicle operating state transmitted from the mobile terminal 200, the operation transmitting unit 112 sets the operating state of the air conditioner 100 to the operating state indicated by the received other vehicle operating state. To control the air conditioning functional parts. In the present embodiment, since the rotation speed of the compressor is in the operating state, the compressor is controlled so that the rotation speed of the compressor is the rotation speed indicated by the determined operating state.

  The other vehicle operating state is transmitted to the air conditioner 100 by the operation change transmitting unit 226 described later when it is determined that the energy consumption in the normal operating state is larger than the energy consumption in the other vehicle operating state. Therefore, when it is determined that the energy consumption in the operating state of the target air conditioner 100a is greater than the energy consumption in the operating state of the other vehicle, the operation control unit 113 sets the operating state of the air conditioner 100a to other states. It will be changed to the operating state indicated by the vehicle operating state.

[Configuration of mobile terminal 200]
The configuration of the mobile terminal 200 will be described with reference to FIG. In this embodiment, a case where a multifunctional mobile phone such as a smartphone is used as the mobile terminal 200 will be described as an example. The mobile terminal 200 includes a near field communication unit 201, a wide area communication unit 202, a touch panel 203, and a control unit 205. The mobile terminal 200 also includes a speaker, a microphone, a camera, and the like (not shown).

  The short-range communication unit 201 is a communication device for communicating with the air conditioner 100 used in the vehicle 10 using the mobile terminal 200, and may perform communication according to the same short-range communication standard as the short-range communication unit 101. .

  The wide area communication unit 202 is a communication device for connecting to the public line network 3 via the base station 2 by performing wireless communication with the base station 2. The touch panel 203 is an input / output device in which a display that displays an image and an input device that can be touched with a finger are integrated.

  The GNSS receiver 204 is a receiver for receiving positioning signals transmitted from a plurality of positioning satellites forming a GNSS (Global Navigation Satellite System) and measuring the position of the GNSS receiver 204.

  The control unit 205 executes a program stored in advance in the ROM and operates as the terminal function unit 210 that realizes a predetermined function as the mobile terminal 200. The terminal function unit 210 includes functions as a position acquisition unit 211, a date / time acquisition unit 212, and a weather acquisition unit 213. In addition to these functions, the terminal function unit 210 also includes functions (not shown) such as a call function.

  The control unit 205 also executes an application program, which is acquired from outside the mobile terminal 200 and additionally stored in the ROM, for realizing the air conditioning control by the air conditioning control system 1. Accordingly, the control unit 205 also operates as the control function unit 220 that realizes the air conditioning control function. The control function unit 220 includes an operation status acquisition unit 221, a vehicle status acquisition unit 222, a statistic storage unit 223, another vehicle operation extraction unit 224, a permission determination unit 225, an operation change transmission unit 226, and an operation record acquisition. The unit 227, the operation record transmission unit 228, the fuel consumption calculation unit 229, and the fuel consumption notification unit 230 are included.

  The position acquisition unit 211 acquires the position of the mobile terminal 200. Specifically, it may be acquired by performing positioning based on the positioning signal received by the GNSS receiver 204. The date and time acquisition unit 212 sequentially acquires the current date and time. The date / time acquisition unit 212 may be realized by, for example, the control unit 205 having a function as a clock. The weather acquisition unit 213 acquires the current weather at the position of the mobile terminal 200. For example, it may be possible to connect to a predetermined server via the base station 2 and the public line network 3, transmit the position of the mobile terminal 200 acquired by the position acquisition unit 211, and return the weather at that position.

  The mobile terminal 200 periodically acquires the date and time, the position of the mobile terminal 200, and the weather at the position as the terminal status in which the mobile terminal 200 is placed by these functions included in the terminal function unit 210. It has a function to do it beforehand. Since the mobile terminal 200 is used in the vehicle 10, the terminal status can be regarded as the vehicle status where the vehicle is placed, and thus the acquired terminal status is used as the vehicle status.

  That is, the target terminal status indicating the status where the mobile terminal 200a is placed, which is acquired by the mobile terminal 200a that is the target mobile terminal, is used as the target vehicle status. In addition, the other vehicle terminal status, which is acquired by the mobile terminal 200b that is the other vehicle mobile terminal and indicates the status where the mobile terminal 200b is placed, is used as the other vehicle status.

  In the present embodiment, when configuring the air conditioning control system 1, since the mobile terminal 200 having such a function is used in advance, the target vehicle condition and other conditions are not provided in the vehicle 10 without providing a member for acquiring the vehicle condition. It is possible to acquire the vehicle status.

  The operating state acquisition unit 221 acquires the normal operating state by communicating with the air conditioner 100 using the short-range communication unit 101.

  The vehicle status acquisition unit 222 acquires at least one of the current date and time, the position of the vehicle 10, and the weather at the position of the vehicle 10 as the vehicle status that is the status in which the vehicle 10 is placed. In the present embodiment, the current date and time acquired by the function included in the terminal function unit 210, the position of the mobile terminal 200, and the weather at the position of the mobile terminal 200 are the current date and time, the position of the vehicle 10, and the position of the vehicle 10, respectively. Considered as the weather and acquired as the vehicle status. Therefore, the vehicle status acquisition unit 222 included in the mobile terminal 200a, which is the target mobile terminal, acquires the status of the vehicle 10a, which is the target vehicle, that is, the target vehicle status. Further, the vehicle status acquisition unit 222 included in the mobile terminal 200b, which is the other vehicle mobile terminal, acquires the status in which the vehicle 10b, which is the other vehicle, has been placed.

  The statistics holding unit 223 holds the operation statistics data acquired by communicating with the data management device 300 using the wide area communication unit 202. For example, it may be held by being stored in the ROM included in the control unit 205. The operation statistical data is acquired, for example, when an application program for realizing air conditioning control is additionally stored in the ROM, and thereafter, the operation statistical data is acquired at a predetermined distribution cycle, and the acquired operation statistical data is acquired. It is sufficient to update the operation statistical data stored in.

  The other vehicle operation extraction unit 224 extracts, as the other vehicle operation state, an average operation state in a vehicle state similar to the vehicle state acquired by the vehicle state acquisition unit 222, based on the operation statistical data held by the statistics holding unit 223. .

  In the present embodiment, a set of vehicle situations in which the vehicle situations are classified is determined, and the trend data associated with the determined set indicates an example of the operating state determined from the tendency of the operating state of the compressor. The average value of the number of rotations is determined as the operating state of the other vehicle. As a result, the average value of the number of revolutions of the compressor in a similar vehicle situation such as the same time zone of the same month and the same weather in the municipality where the vehicle 10 is located is determined as the operating state of the other vehicle.

  Whether or not the permission determination unit 225 indicates that the user of the vehicle 10 operates the touch panel 203 to change the operating state of the air conditioner 100 to the operating state indicated by the operating state of another vehicle. to decide. In this embodiment, each time the user touches and operates the touch panel 203, a virtual button capable of switching between two states, that is, a state indicating permission and a state not permitting is displayed on the touch panel. Thus, the user can set the permitted state and the unpermitted state by operating the virtual button, and the permission determination unit 225 can determine whether or not the permission is indicated according to the display state of the virtual button. Become.

  The operation change transmission unit 226 determines that the permission determination unit 225 indicates that the permission is permitted, and if the energy consumption in the normal operation state is larger than the energy consumption in the operation state indicated by the other vehicle operation state, the operation change transmission unit 226 determines that The distance communication unit 201 is caused to transmit the other vehicle operation state extracted by the other vehicle operation extraction unit 224 to the air conditioner 100. As a result, the operating state of the air conditioner 100 is changed to the operating state indicated by the other vehicle operating state.

  The operation change transmission unit 226 determines that the permission determination unit 225 indicates that the user permits the user to change the operation state to the operation state indicated by the operation state of the other vehicle. It is transmitted to 100, and it changes to the operating state which another vehicle operating state shows. That is, even when the normal operating state consumes more energy than the other vehicle operating state, if the change is not permitted, the normal operating state is continued. Therefore, it is possible to further prevent the operating state from being automatically changed against the user's intention.

  The operation record acquisition unit 227 acquires an operation record including the operation state of the air conditioner 100 and the vehicle status acquired by the vehicle status acquisition unit 222. As a result, in the operation record acquisition unit 227 included in the mobile terminal 200b, the status of the vehicle 10b, which is the other vehicle, acquired by the operation status acquisition unit 221, that is, the status of the other vehicle and the air conditioner 100b that is the other vehicle air conditioner. The operation record including the operation status will be acquired.

  The operating state of the air conditioner 100 is the operating state indicated by the operating state of the other vehicle when the operating change transmission unit transmits the operating state of the other vehicle, and is the operating state when the operating state of the other vehicle is not transmitted. The operating state indicated by the normal operating state acquired by the acquisition unit 221 is obtained. Therefore, the operation record includes the operation state indicated by the other vehicle operation state when the other vehicle operation state is transmitted, and includes the operation state indicated by the normal operation state when the other vehicle operation state is not transmitted.

  The operation record transmission unit 228 causes the wide area communication unit 202 to transmit the operation record acquired by the operation record acquisition unit 227 to the data management device 300.

  The fuel consumption calculation unit 229 determines the fuel consumption of the vehicle 10 in the operating state before changing to the other vehicle operating state, that is, the fuel consumption of the vehicle 10 in the normal operating state, and the operating state after the change, that is, the operating state of the vehicle 10 indicated by the other vehicle operating state. Calculate fuel economy. However, the fuel consumption may be calculated by applying the operating states indicated by the normal operating state and the other vehicle operating state to a predetermined relationship between the operating state and the fuel consumption.

  The fuel consumption notification unit 230 displays on the touch panel 203 the fuel consumption of the vehicle 10 before being changed to the other vehicle operating state and the fuel consumption of the vehicle 10 after being changed, which are calculated by the fuel consumption calculating unit 229, and the user of the vehicle 10 is displayed. To inform. As a result, the user of the vehicle 10 can easily recognize that the fuel economy has been improved by changing the operating state of the other vehicle.

[Configuration of Data Management Device 300]
The configuration of the data management device 300 will be described with reference to FIG. The data management device 300 includes a wide area communication unit 301 and a control unit 310. The wide area communication unit 301 is a communication device for connecting to the public line network 3.

  The control unit 310 functions as an operation record collection unit 311, an operation record storage unit 312, an operation statistics unit 313, and an operation statistics distribution unit 314. The operation record collection unit 311 collects operation records received by the wide area communication unit 301 and transmitted from the mobile terminals 200 used in the plurality of vehicles 10, respectively.

  The operation record holding unit 312 holds the operation record collected by the operation record collection unit 311 in a database (not shown). The database may be realized using a ROM included in the control unit 302, a magnetic disk, or the like.

  The operation statistics unit 313 uses the operation record held by the operation record holding unit 312 to generate operation statistical data. The operation statistics distribution unit 314 causes the wide area communication unit 301 to transmit the operation statistics data generated by the operation statistics unit 313 to the mobile terminal 200 when a predetermined condition for transmitting the operation statistics data is satisfied. The transmission condition is, for example, when the portable terminal 200 is requested to transmit the operation statistical data or when a distribution cycle for distributing the operation statistical data has elapsed.

[Operation of air conditioner 100]
The operation of the air conditioner 100 will be described with reference to the flowchart of FIG. The air conditioner 100 periodically executes the process shown in FIG. 5 from S1 when the vehicle 10 supplies power such as electric power for operating the air conditioner 100.

  In S1, the temperature outside the vehicle, the temperature inside the vehicle, the amount of solar radiation, and the set temperature are acquired. In S2, the target outlet temperature, which is the target temperature of the temperature of the air blown by the air conditioner 100, is determined on the basis of the temperature and the amount of solar radiation inside and outside the vehicle and the set temperature acquired in S1. In S3, the operating state of the air conditioner 100 that realizes the target outlet temperature determined in S2 is determined as the normal operating state. S1, S2, and S3 are processes as the operation determining unit 111.

  In S4, the short-range communication unit 101 is caused to transmit the normal operating state determined in S3 to the mobile terminal 200. S4 is a process as the operation transmission unit 112. In S5, the short-range communication unit 101 determines whether or not the other vehicle operating state transmitted by the mobile terminal 200 is received.

[Summary of Embodiments]
As described above, according to the embodiment described above, the other vehicle operation extraction unit 224 included in the mobile terminal 200a, which is the target terminal, determines the average operating state of the other vehicle based on the operation statistical data in a situation similar to the target vehicle situation. Extract as operating status. The operation control unit 113 operates the air conditioner 100a when the other vehicle operation state extracted by the other vehicle operation extraction unit 224 is determined to consume less energy than the operation state of the air conditioner 100a that is the target air conditioner. Change the state to the operating state indicated by the operating state of the other vehicle.

  At this time, the operation statistical data is the other vehicle air conditioner corresponding to the set of vehicle conditions based on the operation record indicating the correspondence between the other vehicle condition and the operation condition when the other vehicle air conditioner such as the air conditioner 100b is operated. Is generated to show the trend of the operating state of. Therefore, the operation control unit 113 automatically changes the operation state of the air conditioner 100a, which is the target air conditioner, to the average operation state and the operation state in which the energy consumption is reduced. As a result, the air conditioner 100a, which is the target air conditioner, can be brought into an operating state in which the energy consumption is reduced, depending on the situation in which the vehicle is placed.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and the following modified examples are also included in the technical scope of the present invention. Various modifications can be made without departing from the scope. In the following description, elements having the same reference numerals as those used up to now are the same as the elements having the same reference numerals in the previous embodiments, unless otherwise specified. Further, when only a part of the configuration is described, the above-described embodiment can be applied to the other part of the configuration.

<Modification 1>
In the embodiment, the set temperature used is the set temperature input by the vehicle user operating the temperature setting unit 103 provided in the air conditioner 100. However, the vehicle user may operate the mobile terminal 200 to input the set temperature and use the set temperature transmitted from the mobile terminal to the air conditioner 100.

<Modification 2>
In the embodiment, the air conditioning control system 1 includes the operation record acquisition unit 227, the operation record collection unit 311, and the operation statistics unit 313, and the conditions for acquiring, collecting, and statistics the operation records and transmitting the operation statistical data are set. Each time it was established, new operation statistical data was generated. However, it is also possible to adopt a configuration in which only the statistical data generated in advance is used, without newly providing the configuration for generating the statistical operation data.

<Modification 3>
In the embodiment, the function as the control function unit 220 is included in the mobile terminal 200. However, the device having the function as the control function unit 220 is not limited to this. For example, the air conditioner 100 may have a function as the control function unit 220 without using the mobile terminal 200.

<Modification 4>
In the embodiment, the operation control unit 113 controls the air conditioning functional unit 102 to be in the operation state indicated by the other vehicle operation state when it is determined that the normal operation state is larger than the energy consumption of the other vehicle operation state. Was. However, the condition for changing to the operating state in which the energy consumption is smaller is not limited to this. For example, when the accelerator pedal depression amount of the vehicle 10a is greater than or equal to a predetermined threshold value, the operation of the air conditioner 100a is stopped in order to stop the power supplied from the vehicle 10a to the air conditioner 100a and use it for driving the vehicle 10a. The state may be an operation stop state in which the operation is stopped.

  However, the predetermined threshold value is a threshold value for determining whether or not the user of the vehicle 10a indicates an intention to give priority to driving the vehicle 10a rather than operating the air conditioner 100a. In addition, the operation stop state can be realized, for example, by disconnecting the electromagnetic clutch that connects the engine of the vehicle 10a and the compressor included in the air conditioning function unit 102 to stop the rotational force of the engine from being supplied to the compressor. Good. With this, when the user determines that the intention to give priority to driving the vehicle 10a is given to the operation of the air conditioner 100a, the rotational force of the engine is used for the operation of the air conditioner 100a. The open portion can also be used to drive the vehicle 10a.

<Modification 5>
In the embodiment, the permission determination unit 225 displays the virtual button that can be set depending on whether or not the user permits. However, it is also possible to acquire in advance a more detailed setting of the situation permitted by the user, and determine whether or not to permit according to the target vehicle situation and the preset permitted situation. FIG. 8 shows an example of a screen display on which various setting operations can be performed, including an operation for setting a detailed situation in which the user permits changes. The screen of FIG. 8 displays items that allow the user to set whether or not to allow them, and virtual buttons that allow switching between the allowed state and the unpermitted state for each item.

  As an example, the virtual button corresponding to the item "mountain, river, highway is weakened by cooling" is set to the ON position in advance, that is, the state indicating permission is set, and the setting indicating permission is performed. explain. In this case, when the position of the vehicle 10a included in the target vehicle situation is in a predetermined range that is determined to be one of a mountain, a river, and a highway, the permission determination unit 225 causes the user to determine whether the other vehicle is operating. It is judged that it is permitted to change to. On the other hand, when the position of the vehicle 10a is out of those ranges, it is determined that the user does not permit the change to the other vehicle operating state. As a result, the energy consumption of the air conditioner 100a can be reduced according to the user's intention without the user deciding whether or not to permit it.

  Similarly, when the virtual button corresponding to the item "weaker cooling at night" is set to the ON position, it is permitted to change to another vehicle operating state in a predetermined time zone determined to be night. Further, when the virtual button corresponding to the item "rain and cloud is weaker in cooling" is set to the ON position, it is permitted to change to another vehicle operating state in the case of rain and cloud.

  When the virtual button corresponding to the item "stop compressor except in summer" is set to the ON position, it is permitted to stop the compressor according to the operating state of another vehicle when it is determined that it is not summer. Specifically, when the state in which the compressor is stopped is extracted as the operating state of the other vehicle, it is permitted to stop the compressor.

  Further, in addition to the four items for setting whether or not to permit changing to the other vehicle operating state, various setting items are displayed on the screen of FIG. For example, items for setting the stop condition of the compressor, setting of the air volume, the wind direction, etc., and the setting of the engine use when the vehicle 10a is a hybrid car are displayed.
