JP 2008-265549 A Japanese Patent No. 4124035

  However, although the fuel consumption rate of the vehicle changes according to the operating state of the vehicle air conditioner, such as worsening when the load of the vehicle air conditioner is increased, the above Patent Document 1 and Patent In Document 2, there is a problem that even if the operating state of the vehicle air conditioner is adjusted, it is not evaluated that the vehicle is performing energy saving operation.

  This invention is made in view of such a situation, Comprising: The energy saving evaluation apparatus and energy saving evaluation method which can be made to evaluate that it is an energy saving operation according to the driving | running state of a vehicle air conditioner. The purpose is to provide.

In order to solve the above problems, the energy saving evaluation apparatus and the energy saving evaluation method of the vehicle air conditioning control apparatus of the present invention employ the following means.
The present invention is an energy-saving evaluation device applied to the vehicle air conditioner that provides the user with eco-point information that can be used as a privilege according to the operating state of the vehicle air conditioner. Standard acquisition means for acquiring a standard operating state based on the operating state of the air conditioner, operating state detecting means for detecting a current operating state corresponding to the standard operating state, the standard operating state, and the current operating state And eco point output means for outputting the determined eco point information in a state in which the determined eco point information can be delivered to a user. Provided is an energy saving evaluation device applied to a vehicle air conditioner.

  According to such a configuration, the eco point information determined based on the standard operating state determined based on the operating state of the vehicle air conditioner and the detected current operating state can be delivered to the user. Is output in the correct state. The operating state of the vehicle air conditioner is a state of setting information such as the air volume, temperature, and operating time of the vehicle air conditioner, power consumption, and a load of the vehicle air conditioner. The standard operating state refers to the operating state of the vehicle air conditioner that is performed with a standard energy consumption determined according to various conditions such as outside air temperature, solar radiation, weather, occupant, and vehicle configuration. Further, the vehicle form includes vehicle interior volume (vehicle size), windows (design, etc.), luggage compartment (presence of luggage), and the like.

  For example, when the setting information when the air volume of the vehicle air conditioner is in the standard operation state is set to the standard operation state, when the current air volume is detected as a high level, the energy saving performance is reduced, so eco point information is not given, It is determined that the eco point information is given when the current air volume is detected as a low level. Thus, since the eco point information given to the user is determined and output by comparing the standard operation state and the current operation state, the user can perform air conditioning operation in which the vehicle air conditioner saves energy in order to acquire the eco point. Will come to mind.

The standard operation state of the energy saving evaluation device applied to the vehicle air conditioner may be determined based on at least one of the vehicle operation state, the vehicle environment, and the vehicle configuration.
The driving state of the vehicle includes the number of passengers, the vehicle speed, and the like. For example, when the number of occupants is two and the setting temperature of 24 ° C. is set as the standard operation state of the vehicle air conditioner as the setting information, the current set temperature of the vehicle air conditioner is set to 24 by the operation state detection means. When it is detected that the number of occupants is four, the eco point information is given. This is because the temperature inside the vehicle rises due to the increase in the number of passengers, and it is predicted that the passengers will feel uncomfortable, but before the number of passengers increases without changing the set temperature of heating or cooling to the high load side. This is because the same set temperature is used. Or, when increasing the number of passengers, even if the set temperature is not changed, the power of the vehicle air conditioner increases due to the change in load, but if the load of the vehicle air conditioner per person is small, Even if the power increases, eco point information is given.

The vehicle environment is, for example, the amount of solar radiation, the outside air temperature, or the like. For example, when the outside air temperature is 30 ° C. and 25 ° C. is set as the standard operation state as the temperature predicted to be set in the vehicle, if the set temperature (setting information) in the vehicle is 27 ° C., the eco point If the set temperature in the vehicle is 23 ° C., the eco point information is not given.
Further, the vehicle form includes vehicle interior volume (vehicle size), windows (design, etc.), luggage compartment (presence of luggage), and the like. The window design may vary depending on the vehicle type, but for example, the solar load varies depending on whether the window is large or small, with or without a sunroof, etc. .
In this way, eco-point information is determined not only by focusing only on the driving state of the vehicle air conditioner such as setting information, but also by considering the vehicle environment, the vehicle form, and the driving state of the vehicle. Eco point information can be determined according to the specific situation.

The operation state detection means of the energy saving evaluation apparatus applied to the vehicle air conditioner determines a new operation state for bringing the current operation state closer to the corresponding standard operation state, and notifies the user of the new operation state. It is good also as providing a new driving | running state notification means.
If the user changes the operation state of the vehicle air conditioner from the current operation state based on the new operation state determined and notified by the new operation state notification means, the user can be brought closer to the standard operation state. .

The output unit of the energy saving evaluation apparatus applied to the vehicle air conditioner may output the eco point information in a format readable by an external storage medium.
Since the eco-point information in a format that can be read by the external storage medium is output, the user can easily acquire the eco-point information by connecting the external storage medium to the output unit. The external storage medium is a medium that can retain the eco-point information in a state where it does not disappear. For example, non-existing such as USB (Universal Serial Bus) memory, ETC (Electronic Toll Collection: automatic toll collection system), various credit cards, etc. An IC card or the like provided with a contact-type nonvolatile memory.

  The standard acquisition means of the energy saving evaluation device applied to the vehicle air conditioner calculates a first energy consumption that is a first energy consumption amount that is an energy consumption amount of the vehicle air conditioner in the standard operation state. Means and a second energy calculating means for calculating a second energy consumption amount that is an energy consumption amount of the vehicle air conditioner in the current operating state, and the point determining means comprises: The eco point information may be determined based on the first energy consumption and the second energy consumption.

The first energy consumption amount in the standard operation state calculated by the first energy calculation means and the second energy consumption amount detected from the current operation state of the vehicle air conditioner detected by the second energy calculation means. The eco point information is determined on the basis of the information, and is output in a state where it can be transferred to the user.
For example, in the case of an electric vehicle or a hybrid vehicle, a difference occurs between the first energy consumption amount and the second energy consumption amount consumed in an electric motor or the like that operates a blower or a compressor during operation of the vehicle air conditioner. When the second energy consumption is smaller than the one energy consumption, the operation is energy saving. As described above, since the eco point information is determined based on the energy consumption, the eco point information can be determined with high accuracy and can be easily provided to the user.

  The present invention provides a vehicle air conditioner including any one of the above energy saving evaluation devices.

This invention provides the electric vehicle provided with the energy saving evaluation apparatus provided with the said air conditioning apparatus for vehicles.
In an electric vehicle, the amount of electricity used by the vehicle air conditioner affects driving. For this reason, the user can be made aware of energy saving and use the electric vehicle.

  The present invention is applied to a vehicle air conditioner that determines eco-point information that can be used as a privilege according to energy consumption used for air conditioning in a vehicle and provides the eco-point information to a user. An energy saving evaluation method that determines a standard operating state, detects a current operating state with respect to the standard operating state, and represents the eco point representing energy saving based on the standard operating state and the current operating state Provided is an energy saving evaluation method applied to a vehicle air conditioner that determines information and outputs the determined eco point information in a state where it can be delivered to a user.

  The present invention is an energy-saving evaluation program applied to the vehicle air conditioner that provides the user with eco-point information that can be used as a privilege according to the operating state of the vehicle air conditioner. Standard acquisition processing for acquiring a standard operation state based on the operation state of the air conditioner, an operation state detection process for detecting a current operation state corresponding to the standard operation state, the standard operation state, and the current operation state An eco-point determination process for determining the eco-point information representing energy saving based on the information, and an eco-point output process for outputting the determined eco-point information in a state that can be delivered to a user. An energy saving evaluation program applied to the vehicle air conditioner to be executed is provided.

  According to the present invention, energy-saving operation can be evaluated according to the operation state of the vehicle air conditioner.

It is a perspective view showing the state where the air harmony device for vehicles concerning a 1st embodiment of the present invention is arranged in the front of vehicles. It is a functional block diagram of the energy-saving evaluation apparatus which concerns on the 1st Embodiment of this invention. It is a figure which shows schematic structure of a control part and its peripheral device.

  Embodiments of an energy saving evaluation apparatus and an energy saving evaluation method for a vehicle air conditioner according to the present invention will be described below with reference to the drawings. The energy saving evaluation apparatus according to the present invention will be described as applied to a vehicle equipped with an engine, but is not limited thereto. For example, it may be an electric vehicle or a hybrid vehicle.

[First Embodiment]
FIG. 1 is a perspective view showing a state in which a vehicle air conditioner 10 to which an energy saving evaluation device 1 according to the present embodiment is applied is arranged at the front of the vehicle.
The vehicle air conditioner 10 is mainly an air conditioning unit 20 that is an HVAC unit that performs air conditioning such as cooling and heating, a refrigerant system 50 that supplies refrigerant to the air conditioning unit 20 during cooling operation, and a heat source to the air conditioning unit 20 during heating operation. And a control unit 30 (see FIG. 3) that controls the operation of the vehicle air conditioner 10 as a whole.

The configuration of the refrigerant system 50 will be described with reference to FIG.
The refrigerant system 50 is a refrigerant circuit that supplies a low-temperature and low-pressure liquid refrigerant to an evaporator in the air conditioning unit 20, and as shown in FIG. 1, an evaporator (not shown), a compressor 51, A capacitor 52 and an expansion valve 53 are provided.
The evaporator evaporates the liquefied gas refrigerant that has been liquefied by the condenser 52 and has become low-temperature and low-pressure by the expansion valve 53, thereby removing heat from the air passing outside the evaporator and vaporizing the refrigerant in the evaporator.
The compressor 51 compresses the low-temperature and low-pressure gas refrigerant vaporized by taking the heat of the air inside or outside the vehicle with an evaporator, and sends the high-temperature and high-pressure gas refrigerant to the condenser 52. In the case of the vehicle air conditioner 10, the compressor 51 usually receives a driving force for compressing the gas refrigerant by the engine 61 via a belt and a clutch. In the case of an electric vehicle or a hybrid vehicle, the compressor is driven by an electric motor.

The condenser 52 is disposed in the front part of the engine room 26 and discharges the heat of the high-temperature and high-pressure gas refrigerant supplied from the compressor 51 to the outside air to condense and liquefy the gaseous refrigerant. The liquefied refrigerant is sent to a receiver (not shown) for gas-liquid separation, and then only the high-temperature and high-pressure liquid refrigerant is sent to the expansion valve 53.
The expansion valve 53 decompresses and expands the high-temperature and high-pressure liquid refrigerant to form a low-temperature and low-pressure liquid refrigerant and supplies the liquid refrigerant to the evaporator. The expansion valve 53 is generally installed together with an evaporator.

  The heating source system 60 is a hot water circuit that supplies high temperature engine cooling water serving as a heat source to a heater core (not shown) in the air conditioning unit 20, and hot water is supplied from the engine cooling water system that circulates between the engine 61 and the radiator 62. A part of the flow rate is controlled by a water valve (not shown) and introduced into the heater core.

  The control unit 30 controls the operation of the air conditioning unit 20, the refrigerant system 50, and the heating source system 60. Normally, the control unit 30 incorporates a control circuit into an operation panel (described later) 14 on which various settings are made. It is arranged at the center of the instrument panel in the room. The control unit 30 performs selection switching of the operation mode, selection switching of the introduced air by switching operation between the inside air and the outside air, an air volume switching operation of the blower fan, a desired temperature setting operation, and the like.

FIG. 2 is a functional block diagram showing the functions provided in the energy saving evaluation device 1 applied to the control unit 30 in an expanded manner.
The energy saving evaluation apparatus 1 includes a standard acquisition unit (standard acquisition unit) 2, an operation state detection unit (operation state detection unit) 3, an eco point determination unit (eco point determination unit) 4, and an eco point output unit (eco point output). Means) 5 is provided.

  The standard acquisition unit 2 acquires a standard operation state based on the operation state of the vehicle air conditioner 10. The driving state of the vehicle air conditioner 10 is a state of setting information such as the air volume, temperature, and operation time of the vehicle air conditioner 10, power consumption, a load of the vehicle air conditioner 10, and the like. In addition, the standard operation state is performed with a standard energy consumption determined according to various conditions such as outside air temperature, solar radiation, weather, number of passengers, and vehicle configuration (for example, vehicle interior volume, windows, luggage compartment). The operating state of the vehicle air conditioner 10 (required cooling (heating) capacity).

  The load of the vehicle air conditioner 10 is obtained from, for example, the high pressure side pressure of the refrigerant (for example, the discharge pressure of the compressor 51), the low pressure side pressure (for example, the suction pressure of the compressor 51), and the rotation speed of the compressor 51. This is a load of the vehicle air conditioner 10. For example, it is an ability that is directly measured from actual compressor power, blower power, or the like, or calculated from a balance point and compressor rotational speed. Therefore, the setting is input on the operation panel 14, and the operation state of the vehicle air conditioner 10 is determined from the result.

Specifically, in the vehicle air conditioner 10, the standard operation state based on the operation state is given in advance in a table or the like, and when the operation is started, the table is referred to and the standard operation state corresponding to the operation state Is read and acquired. For example, the set air volume and the set temperature in the operation state performed with the standard energy consumption corresponding to the outside air temperature of “30 ° C.” are read from the table, and the read information “air volume level”, “temperature 25 ° C.” Is acquired as the standard operating state.
In the present embodiment, the standard operating state is described as being given by a table or the like, but is not limited to this. For example, it is good also as inputting from the outside, and good also as calculating from a driving | running state.

  The driving state detection unit 3 detects the current driving state corresponding to the standard driving state. For example, the driving state detection unit 3 detects the current air volume, wind speed, temperature, power consumption, load of the vehicle air conditioner 10, and the like of the vehicle air conditioner 10.

  The eco point determination unit 4 determines eco point information representing energy saving based on the standard operation state and the current operation state. Specifically, the eco point determination unit 4 prescribes eco point information according to the difference between the standard operation state and the current operation state, and determines the eco point information to be given to the user based on this difference. . For example, the eco point determination unit 4 is provided with an eco point table that prescribes that the eco point information is proportionally given as the difference between the standard operation state and the current operation state increases. When the difference from the driving state is calculated, the eco point information corresponding to the difference is read with reference to the table. The eco point determination unit 4 determines the read eco point information as eco point information to be given to the user, and outputs it to the eco point output unit 5.

  In the present embodiment, the eco point determination unit 4 is provided with an eco point table that stipulates that more eco point information is proportionally provided as the difference between the standard operation state and the current operation state increases. However, the method of defining the eco point information is not limited to this. For example, the eco point information given according to the difference between the standard operating state and the current operating state may not be proportional. In addition, instead of providing eco-point information in a table, the eco-point determining unit 4 is provided with a function for calculating eco-point information corresponding to the difference between the standard operating state and the current operating state. The point information may be determined.

  The eco point output unit 5 outputs the eco point information acquired from the eco point determination unit 4 in a state in which it can be delivered to the user. The method of delivering eco point information from the eco point determination unit 4 to the user is not particularly limited, and may be directly taken out from the eco point output unit 5 or may be another device that is communicably connected to the eco point output unit 5. It is good also as outputting via. For example, when the eco point output unit 5 includes an interface that can connect an external storage device such as a USB (Universal Serial Bus), the user connects an external storage device such as a USB to the eco point output unit 5. Thus, the eco point information is directly extracted from the eco point output unit 5.

  In addition, as an example of connecting and outputting an eco-point picking device that can communicate with the eco-point output unit 5, for example, the eco-point output unit 5 sends eco-point information to an ETC (Electronic Toll Collection System). Toll collection system) By outputting to the ETC on-board unit a special card for outputting eco-point information that can be output to the on-board unit 16a and reading eco-point information compatible with the ETC on-board unit 16a. Pass point information to various cards. The eco point output unit 5 outputs the eco point information to the dedicated card slot 16b, for example, and passes the eco point information to the dedicated card by inserting a readable dedicated card or the like, or the eco point information to the dedicated reader 16c. The point information is output, and the eco point information is extracted by a medium that can be read through the dedicated reading device 16c. Further, the eco-point information is output to an interface 16d that can be read by a non-contact IC (Integrated Circuit) card connected to the vehicle-side charging cable via a charging device, and the non-contact IC card is brought close to this interface. The eco point information may be read out.

  In addition, the eco point information output by such a configuration is variously measured at a predetermined timing (for example, 10 seconds or 1 minute), for example, during a period in which the vehicle air conditioner 10 is on. It may be calculated based on the information and may be summed, or the average energy consumption and actual time from when the key is inserted into the vehicle to start driving to when the key is removed and driving ends The point may be finally determined from the difference from the consumed energy. Alternatively, the eco point information may be determined by integrating the total power consumption from the start of operation to the end of operation.

  In addition, it is preferable that the standard acquisition part 2 acquires a standard driving | running state based on at least any one among the driving | running state of a vehicle, a vehicle environment, and a vehicle form. The driving state of the vehicle is, for example, the number of passengers, the vehicle speed, and the like. For example, the current operation state of the vehicle air conditioner 10 is compared with the set temperature (for example, 24 ° C.) of the standard operation state during the “cooling” operation when the number of occupants is a predetermined number (for example, two people). When the operating state detection unit 3 detects that the temperature is set (for example, 24 ° C.) and the number of passengers (for example, 4 persons), the eco point information is given. This is because the temperature inside the vehicle rises due to the increase in the number of passengers, and it is predicted that the passengers will feel uncomfortable, but before the number of passengers increases without changing the set temperature of heating or cooling to the high load side. This is because the same set temperature is used. Even if the set temperature is not changed, the power of the vehicle air conditioner 10 may increase due to an increase in the number of passengers and a change in load. If the load per person is small, eco point information may be given.

  The vehicle environment is, for example, the amount of solar radiation or the outside air temperature, and is measured by, for example, a solar radiation amount sensor, an outside air temperature sensor, or the like. The case where the standard operation state (set temperature) of the “cooling” operation when the outside air temperature is 35 ° C. is 23 ° C. will be described as an example. In such a case, if the set temperature (setting information) in the vehicle detected by the driving state detection unit 3 is a set temperature (for example, 25 ° C.) that reduces the load compared to the standard driving state, energy saving is improved. So give eco point information. Further, if the set temperature in the vehicle is a set temperature (for example, 20 ° C.) that increases the load compared to the standard driving state, the energy saving performance is reduced, so eco point information is not given (or eco point information is reduced).

In addition, for example, although the outside air temperature is relatively low in early spring and the like, there are cases where the vehicle air conditioner 10 is used because the amount of solar radiation is large and the inside temperature of the vehicle rises. It is more preferable to evaluate energy saving in consideration of the amount of solar radiation.
As the vehicle environment changes, the followability of the room temperature when air conditioning is performed changes. Therefore, more specific information can be obtained by determining the eco point information by taking into consideration the vehicle environment and the driving state of the vehicle. Eco point information corresponding to various conditions can be determined.

FIG. 3 is a diagram showing a schematic configuration in which the control unit 30 to which the energy saving evaluation device 1 is applied and its peripheral devices are connected.
The control unit 30 includes the energy saving evaluation device 1, and is connected to the operation panel 14, the display device 15, and the eco point extraction device via the communication path 13 so as to be communicable.
The control unit 30 controls the vehicle air conditioner 10 based on setting information and the like of the vehicle air conditioner 10 input by the occupant operating the operation panel 14 and is acquired from the vehicle air conditioner 10. Information on the operation state is output to the energy saving evaluation apparatus 1. In addition, the control unit 30 outputs information such as the current operation state of the vehicle air conditioner 10 to the display device 15.

  The operation panel 14 is a panel in which setting information such as temperature and air volume of the vehicle air conditioner 10 is set by an occupant. Further, the operation panel 14 includes an air conditioner ECO dial, and the strength (compressor on / off set temperature) of the vehicle air conditioner 10 can be changed by the air conditioner ECO dial.

The display device 15 is a device that displays setting information, the current operating state of the vehicle air conditioner 10, eco point information, the degree of energy saving, and the like.
The eco-point picking device is, for example, an ETC vehicle-mounted device 16a, a dedicated card slot 16b, a dedicated reading device 16c, or a device 16d capable of reading with a non-contact IC card. In addition, the eco-point taking-out device may be a standardized device, or may be a reading device developed exclusively for eco-point taking-out.
The communication path 13 is not particularly limited as long as the connected apparatuses can communicate with each other. In the present embodiment, communication is established through a CAN (Controller Area Network).

[Cooling operation]
Next, an energy saving evaluation method having the above configuration will be described.
The case where the vehicle air conditioner 10 is air-cooled will be described with reference to FIG.
As the engine 61 rotates, the compressor 51 is driven. When the gas refrigerant evaporated in the evaporator is sucked into the compressor 51, it is compressed into a high-temperature and high-pressure gas. The gas refrigerant that has reached a high temperature and a high pressure is sent to the capacitor 52. The high-temperature and high-pressure refrigerant is cooled to a liquid refrigerant by running wind caused by running of the vehicle and a cooling fan provided in the condenser 52. The high-temperature and high-pressure liquid refrigerant is sent from the condenser 52 to the expansion valve 53 and is decompressed by the expansion valve 53 to become a low-temperature and low-pressure refrigerant. The low-pressure liquefied gas refrigerant is circulated through the heat exchanger and vaporized, and takes the heat of vaporization from the surroundings to become a gas refrigerant at the outlet of the evaporator. At this time, when the air blown from the blower that sends the wind into the vehicle is applied to the evaporator, the cool air that has been cooled by the removal of the heat of vaporization is sent into the vehicle. As the refrigerant is circulated in this way, cold air is supplied into the vehicle.

[Heating operation]
The case where the vehicle air conditioner 10 is operated for heating will be described with reference to FIG.
The engine cooling water whose temperature has been increased by cooling the engine 61 serves as a heat medium, and a part of which the flow rate is controlled by the water valve is supplied to the heater core in the air conditioning unit 20. The engine coolant flowing into the heater core is heat-exchanged with air introduced by a fan (not shown) or the like. At this time, the air is heated by the sensible heat of the engine cooling water and is sent into the vehicle by a duct or the like, so that warm air is supplied into the vehicle. The engine coolant that has circulated through the heater core is returned to the engine 61 side, and the engine 61 is cooled.
In the case of an electric vehicle or a hybrid vehicle, heating is obtained by operating the above-described refrigeration cycle in a reverse cycle and using the evaporator as a condenser.

[Operation of energy-saving evaluation system]
Next, the operation of the energy saving evaluation apparatus will be described with reference to FIGS.
When the operation panel 14 is operated by an occupant, operation information (for example, cooling operation, set temperature 28 ° C., outside air temperature 35 ° C., etc.) of the vehicle air conditioner 10 is input and the vehicle air conditioner 10 is turned on. When the state is reached, the operation information input by the occupant is output from the operation panel 14 to the control unit 30. The control unit 30 controls the vehicle air conditioner 10 based on the acquired operation information, acquires the current operating state of the vehicle air conditioner 10 (for example, cooling operation, indoor temperature 33 ° C., etc.), The acquired current operating state is output to the energy saving evaluation device 1. In addition, the control unit 30 outputs operation information input from the occupant to the energy saving evaluation apparatus 1.

  The operation information input from the occupant is input to the standard acquisition unit 2 of the energy saving evaluation apparatus 1. The standard acquisition unit 2 reads a standard operation state (for example, cooling operation, set temperature 25 ° C.) corresponding to the operation information based on a table in which the standard operation state is defined, and outputs it to the eco point determination unit 4. In addition, the current operation state input from the vehicle air conditioner 10 is detected by the operation state detection unit 3 as information on the operation state (for example, cooling operation, set temperature 28 ° C.) and output to the eco point determination unit 4. Is done.

  The point determination unit 4 refers to the eco point table and determines eco point information according to the difference between the standard operation state and the current operation state. For example, in the present embodiment, the current operation state (cooling operation, set temperature 28 ° C.) has a smaller load on the vehicle air conditioner 10 than the standard operation state (cooling operation, set temperature 25 ° C.). It is determined that eco point information (for example, 10 points) corresponding to this difference is given to the occupant. The determined eco point information is output to the eco point output unit 5.

The eco point output unit 5 converts the output eco point information (for example, 10 points) into a state in which it can be delivered in order to give it to the occupant (user). The eco point output unit 5 outputs the eco point information to the display device 15 in order to notify the user of the eco point information.
The user grasps the eco point information and the degree of energy saving by confirming the display content of the display device 15, and, at a desired timing, inserts the ETC card into the ETC vehicle-mounted device that is communicably connected to the energy saving evaluation device 1. By inserting, the eco point information is acquired from the ETC card.

  As described above, according to the energy saving evaluation device 1 and the method according to the present embodiment, the standard operation state that is a standard operation state acquired based on the operation state of the vehicle air conditioner 10; The eco point information is determined based on the detected difference from the current driving state, and is output in a state that can be delivered to the user. Users aim to acquire eco-points and try to perform air-conditioning operation in which the vehicle air conditioner saves energy.

  According to the present embodiment, the standard operating state and the current operating state are compared, and the eco point information to be given to the user is determined according to the difference in the comparison result. It is not limited to this. For example, the standard operating state and the current operating state may be converted into energy consumption, and the eco point information may be given according to the difference in the calculated energy consumption.

Specifically, the standard acquisition unit 2 includes a first energy calculation unit (first energy calculation unit) (not shown) and a second energy calculation unit (second energy calculation unit) (not shown).
The first energy calculation unit calculates a first energy consumption amount that is an energy consumption amount of the vehicle air conditioner 10 in the standard operation state, and the second energy calculation unit calculates the vehicle air conditioner 10 in the current operation state. The second energy consumption amount that is the energy consumption amount is calculated.
The energy consumption is calculated based on, for example, the high pressure side pressure of the refrigerant (for example, the discharge pressure of the compressor 51), the low pressure side pressure (for example, the suction pressure of the compressor 51), the rotation speed of the compressor 51, and the rotation speed of the blower.

The point determination unit 4 determines the eco point information based on the first energy consumption and the second energy consumption calculated as described above. Specifically, the eco-point determination unit 4 prescribes eco-point information corresponding to the difference between the first energy consumption and the second energy consumption, and the eco-point information given to the user based on this difference To decide. For example, the eco point determination unit 4 includes an eco point table that prescribes that as the difference between the first energy consumption and the second energy consumption increases, more eco point information is proportionally provided. When the difference between the energy consumption amount and the second energy consumption amount is calculated, the eco point information corresponding to the difference is read with reference to the table. The eco point determination unit 4 determines the read eco point information as eco point information to be given to the user, and outputs it to the eco point output unit 5.
Thus, by determining the eco point information based on the energy consumption, it is possible to determine the eco point information with high accuracy and easily provide it to the user.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
The energy saving evaluation apparatus of this embodiment is different from the first embodiment in that a new operation state notification unit (new operation state notification means) (not shown) is provided in the operation state detection unit 3. Hereinafter, regarding the energy saving evaluation apparatus 1 of the present embodiment, description of points that are common to the first embodiment will be omitted, and different points will be mainly described.

  Since it is energy saving not to use energy, it seems that it is preferable not to use the vehicle air conditioner 10 in any case. However, when energy saving is considered from the viewpoint of the energy of the entire vehicle. However, not necessarily using the vehicle air conditioner 10 is not necessarily energy saving. In the present embodiment, energy is captured from the viewpoint of the entire vehicle, and a more preferable operating state of the vehicle air conditioner 10 is notified in order to improve energy saving.

  The new operation state notification unit determines a new operation state for bringing the current operation state closer to the corresponding standard operation state, and notifies the user of the new operation state. Specifically, the new driving state notifying unit reads the standard driving state corresponding to the current driving state from the eco point table provided in the eco point determining unit 4. Subsequently, the new operation state notifying unit displays the read standard operation state or a preferable operation state determined based on the relationship between the read standard operation state and the current operation state on the display device 15 (see FIG. 3) or the like. To output the energy saving operation state. Thus, the occupant can grasp a preferable driving state based on the notified contents.

  For example, when the electric vehicle is traveling on a highway, the indoor temperature in the vehicle is 30 ° C., and the outside air temperature is 25 ° C., when the electric vehicle window is not fully opened and the vehicle air conditioner 10 is not used. The two driving methods when using the vehicle air conditioner 10 with the window of the electric vehicle fully closed will be described.

When all the windows of the electric vehicle are fully opened, the air resistance received by the vehicle is larger than when the windows are closed, so that the room temperature can be lowered without using the vehicle air conditioner 10 However, depending on the vehicle speed, the load on the motor that drives the vehicle may increase.
On the other hand, when the vehicle air conditioner 10 is used with the window of the electric vehicle fully closed and the set temperature (for example, 28 ° C.) set so that the difference from the room temperature in the vehicle is within a predetermined range. Depending on the vehicle speed, the load applied to the motor for driving the vehicle may be smaller than when the window is fully opened, and the energy consumed by the vehicle as a whole may be reduced.

As described above, even when the vehicle air conditioner 10 is used, the energy consumed by the entire vehicle may be reduced depending on the vehicle speed. The setting information of preferable driving | operations, such as the presence or absence of use of the vehicle air conditioner 10, is notified.
Thereby, when the user is unconsciously using the vehicle air conditioner 10 in an operation state in which energy is not saved, the user can be notified of the state in which the energy saving operation is performed. By confirming this, it becomes possible to easily switch to energy saving operation.
