Description

  The present invention relates to an air conditioning control device that controls the operation of an air conditioning device, and relates to an air conditioning control device that determines whether or not a user setting of an air conditioning operation is environmentally conscious.

  Traditionally, efforts to reduce greenhouse gas emissions have been emphasized. Specifically, it is recommended that the cooling is set to 28 degrees and the heating is set to 20 degrees, or the exhaust gas discharged from the vehicle is technically reduced. Similarly, with respect to the behavior of the air conditioner itself, it has been devised to perform optimal control based on the surrounding environment as disclosed in Patent Document 1.

  In addition, the air conditioner of a vehicle may be used for the purpose of removing the cloudiness (condensation) of a window other than control of a vehicle room temperature. Since the clouding of the window cannot be effectively removed by the operation that is suppressed such as the energy saving mode, Patent Document 2 discloses that the clouding of the window is performed even when the energy saving mode is selected as the compressor mode of the in-vehicle air conditioner. Disclosed is a technology that prioritizes cooling when detecting.

  In addition to the operation control on the vehicle side, in recent years, a technology has been devised that encourages users to take environmentally conscious actions by providing information to users and evaluating user actions. For example, Patent Literature 3 discloses a technique for evaluating whether or not a user has used it in consideration of the environment based on the user's efforts, and Patent Literature 4 discloses an energy saving temperature every time a temperature setting button is operated. A technique for prompting the user to save energy by displaying a range threshold on a remote control display unit is disclosed.

  Furthermore, patent document 5 is disclosing the technique notified to a user by displaying specific electric energy and power saving related information. Similarly, Patent Document 6 discloses a technique that allows a vehicle user to easily recognize how the fuel consumption changes when the set temperature is changed.

JP-A-5-310028 Japanese Patent Laid-Open No. 62-227809 JP 2006-16443 A JP 2006-125668 A JP 2003-220907 A JP 2003-166868 A

  By the way, when evaluating a user's operation input, for example, by simply comparing and evaluating the set room temperature (target room temperature of the air conditioner) input by the user and the ideal set temperature with a small environmental load, the accuracy of the evaluation Becomes lower.

  Specifically, if the vehicle room temperature is very high at the time of boarding the vehicle, no matter what set temperature the user inputs, the maximum cooling is performed until the vehicle room temperature drops to some extent. Reduce the car room temperature. Therefore, even if the user inputs the ideal set temperature of 28 degrees or 18 degrees, the operation state of the air conditioner remains the same for a while.

  Although the operation of the air conditioner itself is the same as described above, it is inappropriate to evaluate the user operation based only on the set temperature.

  Further, in an air conditioner for a vehicle, the air conditioner may be used for the purpose of removing clouding (condensation) of a window. In such a situation, it is necessary to remove the fog quickly in order to secure the driver's field of view and ensure the safety of driving, so the capacity of the air conditioning equipment should be exercised to the maximum. It is inappropriate to evaluate a user's operation based only on an action.

  However, the conventional technique does not take into consideration such a substantial operating state of the air conditioner and the operation purpose of the air conditioner, and thus there is a problem that the user operation cannot be evaluated with high accuracy. If the accuracy of the evaluation is low, the reliability of the user with respect to the evaluation result is lowered, and the user cannot be encouraged to take an action in consideration of the environment.

  The present invention has been made in order to solve the above-described problems in the prior art and to solve the problems. In consideration of the substantial operating state of the air conditioner and the operation purpose of the air conditioner, the user can operate the air conditioner. An object of the present invention is to provide an air-conditioning control device with improved accuracy in determining whether or not an environmentally-friendly device.

  In order to solve the above-described problems and achieve the object, the air conditioning control device according to the present invention determines the operation content of the air conditioning equipment based on the user input, and the user input or operation content and the ideal input content or An air conditioning control device that compares an ideal operation content and evaluates an air conditioning operation based on a user input, and changes an evaluation criterion by the evaluation unit based on an internal temperature of an air conditioning control target space, or the evaluation unit Stop evaluation by.

  In addition, the air conditioning control device according to the present invention receives the target air temperature of the air conditioning control target space as a user input, calculates an ideal target temperature based on the outside air temperature, and obtains the air conditioning equipment obtained from the target temperature by the user input The user input is evaluated by comparing the operation content of the air conditioner with the operation content of the air conditioner obtained from the ideal target temperature.

  In addition, the air conditioning control device according to the present invention is in the operation of the defroster that removes the glass fogging within a predetermined period after the user gets on, when evaluating the user input or the operation content of the air conditioning equipment based on the user input. Is excluded from evaluation.

  According to the present invention, the air conditioning control device compares the user input or operation content with the ideal input content or ideal operation content and evaluates the air conditioning operation based on the user input. The evaluation criteria by the evaluation means are changed based on the internal temperature, or the evaluation by the evaluation means is stopped, so that the user's operation of the air conditioning equipment considers the environment in consideration of the substantial operating state of the air conditioning equipment. It is possible to obtain an air-conditioning control device that determines whether or not it is highly accurate.

  Further, according to the present invention, the air conditioning control device receives the target temperature of the air conditioning control target space as a user input, calculates an ideal target temperature based on the outside air temperature, and obtains the air conditioning equipment obtained from the target temperature by the user input. Because the user input is evaluated by comparing the operation details of the air conditioner and the operation details of the air conditioner obtained from the ideal target temperature, the user's operation of the air conditioner considers the environment based on the actual operating state of the air conditioner Thus, there is an effect that it is possible to obtain an air conditioning control device that determines with high accuracy whether or not it is.

  In addition, according to the present invention, the air conditioning control device operates a defroster that removes the glass fogging within a predetermined period after the user gets on the board when the user inputs or the operation content of the air conditioning equipment based on the user input is evaluated. Air conditioning control that accurately determines whether the user's operation of the air conditioning equipment is environmentally conscious based on the actual operating state of the air conditioning equipment and the purpose of operating the air conditioning equipment. There exists an effect that an apparatus can be obtained.

  Exemplary embodiments of carrying an air-conditioning control apparatus according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a schematic configuration diagram showing a schematic configuration of an in-vehicle air conditioning control device 10 according to an embodiment of the present invention. As shown in the figure, the air conditioning control device 10 includes a setting input unit 21, an outside air temperature sensor 22, a vehicle room temperature sensor 23, an engine water temperature sensor 24, a defroster 25, a compressor 31, a blower 32, an air mix actuator 33, a display 41, The speaker 42 is connected.

  The setting input unit 21 is input receiving means for receiving an operation input such as ON / OFF of an air conditioning operation and a target vehicle room temperature from a user (a vehicle driver or the like), and is realized by a switch, a touch panel, or the like. The outside air temperature sensor 22 is a sensor that measures the temperature outside the vehicle, and the vehicle room temperature sensor 23 is a sensor that measures the temperature inside the vehicle interior that is the air-conditioning target space. The engine water temperature sensor 24 is a sensor that measures the temperature of engine cooling water, and the defroster 25 is a mechanism that removes cloudiness and condensation on the glass (mainly the rear window) of the vehicle.

  The compressor 31, the blower 32, and the air mix actuator 33 are in-vehicle air conditioners, and the air that has been cooled by circulating the refrigerant by the compressor 31 and the air that has been warmed by the engine coolant at a predetermined ratio by the air mix actuator 33. The mixture is mixed and blown out into the passenger compartment by the blower 32.

  The display 41 and the speaker 42 are output means for providing information to the user by display output and audio output, respectively. The display 41, the speaker 42, and the setting input unit 21 can be shared with other in-vehicle devices such as a navigation system and a car audio system.

  The air conditioning control device 10 is a device that controls the operation of an in-vehicle air conditioner such as the compressor 31, the blower 32, and the air mix actuator 33, and includes an air conditioning operation setting unit 11, an eco evaluation unit 12, an ideal state calculation unit 13, A boarding determination unit 14 and a defroster operation detection unit 15 are provided.

  The air conditioning operation setting unit 11 determines the operation content of the in-vehicle air conditioner (the compressor 31, the blower 32, and the air mix actuator 33) based on the user input, the passenger compartment temperature, and the like, and the operation of each in-vehicle air conditioner according to the determined operation content. The process which controls is performed.

  For example, when a user input is performed to cool the vehicle at a target room temperature of 20 degrees, the air conditioning operation setting unit 11 controls the operation of the in-vehicle air conditioner while monitoring the measurement result of the vehicle room temperature sensor 23, so that the vehicle room temperature is set. The cooling operation is executed so as to be 20 degrees.

  The eco evaluation unit 12 is a processing unit that evaluates whether the air conditioning operation based on the user input is environmentally conscious. Specifically, the eco-evaluation unit 12 compares the set room temperature (target temperature in the passenger compartment) input by the user with an ideal set temperature with a low environmental load, and the set room temperature input by the user is the target room temperature. If the value is within the predetermined range, it is determined that the setting is suitable for the environment, and if it is outside the predetermined range, it is determined that the setting is inappropriate.

  The ideal set temperature is set by the ideal state calculation unit 13 based on the outside air temperature. For example, if the outside temperature is 38 degrees or less during cooling, the ideal set temperature may be 28 degrees, and if it exceeds 39 degrees, the correspondence may be held as a map, such as 25 degrees. The temperature may be derived. Further, the ideal state calculation unit 13 may obtain an ideal operation state of the in-vehicle air conditioner without being limited to the set temperature.

  The eco-evaluation for the user operation is repeatedly performed at predetermined time intervals, for example, during operation of the in-vehicle air conditioner. Then, the obtained determination results are integrated and output by the display 41 or the speaker 42, thereby prompting the user to perform setting in consideration of the environment. Here, the case where the user is notified of the result of the eco-evaluation is described as an example. However, the result of the eco-evaluation is not limited to this, and can be used universally by an arbitrary method.

  By the way, when evaluating the user's operation input, for example, if the set room temperature (target temperature of the air conditioner) input by the user and the ideal set temperature with a small environmental load are simply compared and evaluated, the accuracy of the evaluation May be lower.

  For example, as shown in FIG. 2, when the vehicle room temperature is very high (36 degrees in the figure) at the time of boarding the vehicle, the vehicle room temperature decreases to some extent no matter what set temperature the user inputs. Until it is done, cool the vehicle as much as possible to lower the vehicle room temperature.

  Therefore, as shown in the room temperature transition A1 and the room temperature transition A2, even if the user inputs the ideal set temperature of 28 degrees or 18 degrees at the start of the air conditioning operation (time t1), for a while The operation state of the air conditioner is the same (until time t1 in the figure).

  For this reason, after sufficient time has elapsed since the start of air conditioning (for example, at time tn), it is possible to evaluate the load on the environment of the in-vehicle air conditioner by comparing the set temperature input by the user. It is difficult to accurately evaluate this state.

  Therefore, the air-conditioning control device 10 improves the evaluation accuracy by comparing the substantial operation of the air-conditioning equipment, changing the threshold value of the eco-evaluation in a specific state such as immediately after boarding, or excluding it from the evaluation target for the specific state period. Yes.

  As shown in FIG. 3, the control identity determination unit 12 a operates the vehicle air conditioner operation content obtained by the air conditioning operation setting unit 11 based on the temperature set by the user input (for example, the air direction and air volume of the blower 32, the air mix actuator 33 The air mix setting, the internal circulation and the setting state of the introduction of the outside air, etc.) and the operation content of the in-vehicle air conditioner calculated based on the ideal set temperature calculated by the ideal state calculation unit 13 are performed.

  In this way, it is possible to accurately evaluate the user setting contents by comparing the substantial air conditioning operation by the air conditioning operation setting unit 11 instead of directly comparing the user setting contents.

  The processing operation of the air conditioning control device 10 in this case is shown in FIG. The flowchart shown in the figure is a processing operation repeatedly executed during the operation of the in-vehicle air conditioner.

  As shown in the figure, first, the ideal state calculation unit 13 calculates an ideal set temperature from the outside air temperature (step S101), and the air conditioning operation setting unit 11 obtains an ideal air conditioning operation from the ideal set temperature ( Step S102).

  Subsequently, the air conditioning operation setting unit 11 obtains an actual air conditioning operation from the set temperature input by the user (step S103), and the eco evaluation unit 12 compares the ideal air conditioning operation with the actual air conditioning operation (based on the user input). (Step S104).

  As a result, if the difference in the air conditioning operation is within the allowable range (step S105, Yes), the eco evaluation unit 12 determines that the setting is suitable (step S106), and if not within the allowable range (step S105, No), it is determined that the setting is inappropriate (step S107), and the process ends.

  Next, the processing operation of the air-conditioning control apparatus 10 when changing the threshold value of the eco-evaluation in a specific state such as immediately after boarding or excluding it from the evaluation target for the specific state period will be described.

  FIG. 5 shows the processing operation of the air conditioning control device 10 when the vehicle room temperature is outside the predetermined range and is excluded from the evaluation target by the eco evaluation unit 12. In this process, if the passenger compartment is very hot in summer or if the passenger compartment is very cold in winter, the temperature in the passenger compartment is not sufficiently controlled immediately after the user gets on the vehicle. It is estimated that the vehicle is in a state and excluded from the eco-evaluation target, and the eco-judgment is performed after the vehicle room temperature falls within a predetermined range.

  Specifically, the boarding determination unit 14 first acquires the vehicle room temperature measured by the vehicle room temperature sensor 23 (step S201). If the vehicle room temperature is not within the predetermined range (step S202, No), the boarding determination unit 14 It is determined that the state is immediately after boarding, and the evaluation exclusion processing unit 12c interrupts the evaluation and ends the processing.

  On the other hand, if the vehicle room temperature is within the predetermined range (step S202, Yes), the ideal state calculation unit 13 calculates an ideal set temperature from the outside air temperature (step S203), and the eco evaluation unit 12 sets the user input. The temperature is compared with the ideal set temperature calculated by the ideal state calculation unit 13 (step S204).

  As a result, if the difference between the set temperatures is equal to or less than the threshold (step S205, Yes), the eco-evaluation unit 12 determines that the setting is suitable (step S206), and if not within the allowable range (step S205, No), It is determined that the setting is inappropriate (step S207), and the process ends.

  Further, the processing operation shown in FIG. 6 is a processing operation of the air-conditioning control apparatus 10 when the evaluation threshold value by the eco-evaluation unit 12 is changed when the vehicle room temperature is outside the predetermined range. In this process, if the passenger compartment is very hot in summer or if the passenger compartment is very cold in winter, the temperature in the passenger compartment is not sufficiently controlled immediately after the user gets on the vehicle. Estimating that it is in a state, temporarily changing the eco-evaluation threshold, and performing eco-judgment.

  Specifically, the boarding determination unit 14 first acquires the vehicle room temperature measured by the vehicle room temperature sensor 23 (step S301). If the vehicle room temperature is not within a predetermined range (step S302, No), the boarding determination unit 14 It is determined that the state is immediately after boarding, and the threshold value changing unit 12b changes the evaluation threshold value (step S303).

  When the vehicle room temperature is within the predetermined range (step S302, Yes), or after changing the threshold value of the set temperature comparison (step S303), the ideal state calculation unit 13 calculates the ideal set temperature from the outside air temperature (step S304). The eco-evaluation unit 12 compares the set temperature input by the user with the ideal set temperature calculated by the ideal state calculation unit 13 (step S305).

  If the difference between the set temperatures is equal to or less than the threshold (step S306, Yes), the eco evaluation unit 12 determines that the setting is suitable (step S307), and if not within the allowable range (step S306, No), It determines with it being an appropriate setting (step S308), and complete | finishes a process.

  In FIGS. 5 and 6, the boarding determination unit 12 determines whether or not the vehicle is in a state immediately after boarding based on the vehicle room temperature. However, any method can be used for boarding determination. For example, it may be determined from the coolant temperature of the engine whether or not the vehicle is in a state immediately after boarding, a change in pressure applied to the seat seat surface may be detected, or image recognition may be used.

  In addition to immediately after boarding, when air conditioning equipment is operated for the purpose of removing clouding (condensation) of the window, it is necessary to remove the fog quickly in order to secure the driver's field of view and ensure driving safety. Therefore, the capacity of air conditioning equipment should be exercised to the maximum.

  Therefore, the air-conditioning control device 10 uses the eco-evaluation unit 12 when the defroster 25 is operating within a predetermined time from the boarding, that is, when the user is performing an operation for removing the cloud of the window. Exclude from evaluation. The processing operation of the air conditioning control device 10 in this case is shown in FIG.

  In the flowchart shown in the figure, first, the boarding determination unit 14 determines the user's boarding state from the vehicle room temperature, the engine water temperature, and the like, and if it is within a predetermined time from boarding (step S401, Yes), the evaluation exclusion processing unit 12c interrupts the evaluation and terminates the process.

  Similarly, the defroster operation detection unit 15 monitors the operation state of the defroster 25. If the defroster 25 is operating (step S402, Yes), the evaluation exclusion processing unit 12c interrupts the evaluation and performs processing. Terminate.

  On the other hand, if the defroster is not in operation (step S402, No), the ideal state calculation unit 13 calculates an ideal set temperature from the outside air temperature (step S403), and the eco evaluation unit 12 calculates the set temperature input by the user. The ideal setting temperature calculated by the ideal state calculation unit 13 is compared (step S404).

  As a result, if the difference between the set temperatures is equal to or less than the threshold value (step S405, Yes), the eco evaluation unit 12 determines that the setting is suitable (step S406). It determines with it being an appropriate setting (step S407), and complete | finishes a process.

  As described above, the air-conditioning control apparatus 10 according to the present embodiment compares the substantial operation of the air-conditioning equipment, changes the threshold value of the eco-evaluation in a specific state such as immediately after boarding or during cloudy removal, and excludes it from the evaluation target. By performing the above, it is accurately evaluated whether or not the user's operation of the air conditioning equipment is environmentally friendly, and the user is notified. Therefore, the reliability of the user with respect to the evaluation result can be improved, and the user can be effectively encouraged to take an action in consideration of the environment.

  In this embodiment, the case where the user sets the target room temperature in the cooling operation has been described as an example. However, the present invention is not limited to this, and can be applied to the heating operation. However, it is also applicable when individually specifying and inputting the wind direction, air volume, air mix setting, switching between internal circulation and outside air introduction.

  In addition, in a vehicle air conditioner powered by an engine, the present invention is based on a mechanism in which air heated by engine cooling water and air cooled by a refrigerant circulated by a compressor are mixed and blown into the vehicle interior. The degree of consideration for the environment evaluated by the user does not necessarily match the degree of influence on the actual environment. In other words, in the present invention, rather than how much the user's operation actually affects the environment, whether or not the user himself / herself takes an action in consideration of the environment is qualitatively evaluated, so that the user's action guideline Is presented.

  As described above, the air-conditioning control apparatus according to the present invention is useful for reducing the load on the environment due to air-conditioning, and is suitable for highly accurate evaluation of user settings.
