Description

  The present invention relates to an in-vehicle air conditioning system for vehicles, particularly automobiles.

JP 2004-306822 A

  Conventionally, the relationship between air conditioning and sound in the passenger compartment has tended to be recognized as interfering with each other. In other words, if priority is given to the performance of the air conditioner, the sound output becomes difficult to hear due to noise such as blowout sound accompanying the air conditioning output. On the other hand, if priority is given to the ease of hearing of the sound output, air conditioning is difficult. There was a recognition that the output level of the device must be suppressed to suppress the generation of noise.

  Therefore, as a technique for changing the air conditioning output and the sound output in conjunction with each other, for example, a technique for changing the blowout output level from the air conditioner according to the sound output level is disclosed in Patent Document 1.

  By the way, in the air conditioning apparatus for vehicles, further improvement in air conditioning capability and energy saving are still required in recent years.

  The subject of this invention is providing the vehicle-mounted air conditioning system which can aim at the further capability improvement and energy saving.

In order to solve the above-described problem, an in-vehicle air conditioning system is provided with an air conditioning output based on operation input information from an air conditioning output state setting operation unit or based on the operation input information and detection result information from an air conditioning sensor. An in-vehicle air conditioning system comprising air conditioning output state setting means for setting a state and air conditioning output control means for performing air conditioning output control based on the set air conditioning output state,
An air conditioning image acoustic data storage unit that stores the air conditioning image acoustic data reflecting the image related to the setting content of the air conditioning output in association with each air conditioning output state;
Air conditioning image acoustic data selection means for selecting the corresponding air conditioning image acoustic data from the air conditioning image acoustic data storage unit based on the setting content of the air conditioning output state;
Air-conditioning image sound data reproduction output means for reproducing and outputting the selected air-conditioning image sound data into the vehicle interior;
It is characterized by providing.

  In the present invention, the vehicle interior sound that has been conventionally recognized to be in a hindering relationship with the vehicle interior air conditioning is configured to function as an assisting function for vehicle interior air conditioning. That is, at the time of air conditioning output, by simultaneously reproducing and outputting the air conditioning image acoustic data reflecting the image related to the setting contents of the air conditioning output, the user can reproduce not only the physical air conditioning effect by the air conditioning airflow but also the air conditioning image acoustic data. By listening to the output sound, an image similar to the physical air conditioning effect can be obtained and the psychological air conditioning effect can be felt. In other words, the present invention has a configuration in which a synergistic air conditioning effect can be obtained by both the physical and psychological aspects, and further improvement of the air conditioning capability is achieved compared to the conventional art.

  The air conditioning output state includes a cooling output state and a heating output state, and the air conditioning image acoustic data storage unit stores air conditioning image acoustic data different from each other in the cooling output state and the heating output state in association with each other. The air-conditioning image acoustic data selection means can be configured to specify the cooling output state and the heating output state and select the corresponding air-conditioning image acoustic data from the air-conditioning image acoustic data storage unit. According to this configuration, in the cooling output state and the heating output state, it is possible to reproduce and output the air-conditioning image sound data reflecting the images of the respective states, so that the cooling effect and the heating effect can be further increased.

  Further, the air conditioning image acoustic data is stored in the air conditioning image acoustic data storage unit in association with the air conditioning output level in the cooling output state, and the air conditioning image acoustic data selection means specifies the air conditioning output level in the cooling output state. In addition, it can be configured to select the air-conditioning image acoustic data that increases the cool feeling as the specified air-conditioning output level increases. As a result, the air-conditioning image acoustic data having a cooler image is reproduced and output as the vehicle interior is hot and it is desired to exert a greater cooling capacity, so that the user can feel cooler more quickly.

  Similarly, the air conditioning image acoustic data is stored in the air conditioning image acoustic data storage unit so as to correspond to the air conditioning output level in the heating output state. After specifying the difference, it is possible to select the air-conditioning image sound data that increases the warmth as the specified air-conditioning level increases. As a result, the warmer image of the air-conditioning image acoustic data is reproduced and outputted as the passenger compartment is colder and the heating capacity is desired to be exhibited more greatly, so that the user can feel the warmth more quickly.

  Further, the air conditioning image acoustic data is classified into a plurality of types, and the air conditioning image acoustic data is stored in the air conditioning image acoustic data storage unit in association with the types. Based on the setting contents, the corresponding type of air-conditioning image acoustic data can be selected from the air-conditioning image acoustic data storage unit. According to this configuration, classification of sound effect and music is performed on the air-conditioning image acoustic data, and the level of contribution to the air-conditioning effect for each type is determined, and then the air-conditioning airflow is set. According to the air conditioning output level determined from the setting content of the air conditioning output state, such as the temperature difference between the temperature and the temperature detected by the in-vehicle temperature detecting means and the blown air volume, the type of air conditioning image acoustic data having an appropriate contribution level is selected. be able to. That is, when the air conditioning output level is high, a type having a high contribution level to the air conditioning effect can be selected, and when the air conditioning output level is low, a type having a low contribution level to the air conditioning effect can be selected. Thereby, an appropriate type of air conditioning image sound data corresponding to the air conditioning output level is reproduced and output. In particular, when the air conditioning output level is high, the user can feel a desired warmth earlier.

  By the way, when the air conditioning image sound data is reproduced and output to the air conditioning output control means, the air conditioning output state correction means for correcting the air conditioning output state set by the air conditioning output state setting means in a direction to lower the air conditioning output level. The air conditioning output control means can be configured to perform air conditioning output control based on the corrected air conditioning output state. According to this configuration, energy saving can be achieved by reducing the actual air conditioning output level by the amount of the air conditioning effect due to the reproduction output of the air conditioning image acoustic data.

  In the case of the above configuration for correcting the air conditioning output, an in-vehicle temperature detecting means for detecting the in-vehicle temperature is provided as an air conditioning sensor, and the air-conditioning output state correcting means has an air-conditioning air flow outlet temperature detected by the in-vehicle temperature detecting means. Can be corrected to approach. In addition, the air conditioning output state correction means can perform correction to reduce the air flow rate of the air conditioning airflow. In these cases, the correction of the air conditioning output state can be easily performed by changing the control parameter for setting the air conditioning output state.

  In the case of the above configuration for correcting the air conditioning output, the air conditioning image acoustic data is stored in the air conditioning image acoustic data storage unit in association with the correction content by the air conditioning output state correction unit, and the air conditioning output state correction unit Can be configured to correct the air conditioning output state with the correction content corresponding to the air conditioning image acoustic data selected by the air conditioning image acoustic data selection means. According to this configuration, when the air conditioning image acoustic data is selected by the air conditioning image acoustic data selection means, the correction content of the air conditioning output state can be grasped only by reading the correction content corresponding to the selected air conditioning image acoustic data. Correction processing can be simplified.

  By the way, in the present invention, it is possible to provide a hearing air conditioning output sound listening assistance means for assisting the listening of the auditory air conditioning output sound that is output into the vehicle with the reproduction output of the air conditioning image acoustic data by the air conditioning image acoustic data reproduction output means. . Thereby, it becomes easy to hear the reproduction output of the air-conditioning image acoustic data, and it becomes easy to obtain the air-conditioning effect.

  The hearing air conditioning output sound listening assistance means can be configured to change the hearing assistance level of the hearing air conditioning output sound based on the setting contents of the air conditioning output state. For example, the sound output state setting means assists the listening of the hearing air-conditioning output sound by changing the playback volume of the air-conditioning image sound data, and changes and sets the playback volume as the hearing assistance level of the hearing air-conditioning output sound And can. Specifically, the auditory air-conditioning output sound listening assistance means can set the reproduction volume to be larger as the air-conditioning air flow is larger. As the air conditioning output level in the vehicle interior increases, noise such as blowout noise increases. Therefore, according to the above configuration, the noise level is judged from the setting contents of the air conditioning output state, and the auditory air conditioning output sound is reliably transmitted to the user. You can set the playback volume that you can hear. Also, an air temperature sensor is provided as an air conditioning sensor to detect the temperature inside the vehicle, and the hearing aid for listening to the air conditioning air conditioning output sound is reproduced as the temperature difference between the air-conditioning air flow setting temperature and the temperature detected by the vehicle temperature detecting means increases. By setting the volume to a large value, it is also possible to assist in listening to the sound output of the auditory air conditioning. In these cases, the change of the listening assistance level can be easily changed by using the control parameters such as the temperature difference and the blown air volume used for the air conditioning control.

  In addition, the air-conditioning image sound which changes the air-conditioning image sound data memorize | stored in association with each air-conditioning output state in the air-conditioning image sound data storage part based on the input operation content to a predetermined air-conditioning image sound data change operation part Data changing means can be provided. Thereby, the air-conditioning image sound data reproduced and output in each air-conditioning output state can be changed according to the user's preference.

  By the way, in the vehicle-mounted air conditioning system 1 having the above configuration, the HDD (air conditioning image acoustic data storage unit) 200H of the navigation device 200 reflects an image related to the setting content of the air conditioning output as shown in FIG. Acoustic data is stored in association with each air conditioning output state. The air conditioning output state is classified into a cooling output state and a heating output state, and the HDD 200H stores different air conditioning image acoustic data in association with the cooling output state and the heating output state, respectively. Yes. In addition, among the classifications of the cooling output state and the heating output state, the air-conditioning image acoustic data is classified into a plurality of types (acoustic types) and stored in the HDD 200H. In the present embodiment, the air conditioning image sound data is classified by sound effect and music. In addition, music may be classified according to genres such as classical music and pop music, or may be classified with or without a song. In the present embodiment, as shown in FIG. 5, for each of the cooling output state and the heating output state, classification is performed by contribution to sound effects and music, and the air conditioning image sound corresponding to each type is provided. Data is registered.

  In the present embodiment, the registered contents can be changed by the user. That is, the air-conditioning image acoustic data stored in association with each air-conditioning output state in the HDD 200H can be changed based on the input operation content to a predetermined operation unit (air-conditioning image acoustic data rewriting operation unit). As shown in FIG. 6, since the plurality of air-conditioning image acoustic data is already stored in the HDD 200 </ b> H for each type classification, the display is performed based on an operation to a predetermined operation unit provided in the display device 210. The air conditioning image acoustic data setting change screen 210 or 220 shown in FIG. 7 is displayed on the screen of the apparatus 210, and the touch switches 211 (211a to 211h) and 221 (221a to 221h) on the screen are displayed for each type classification. In the form of selecting the air-conditioning image acoustic data, the air-conditioning image acoustic data currently set for each type classification can be changed to another one. In the present embodiment, from the screen 210 or 220, first, the touch switches 211a, 211b or 221a, 221b are touch-operated, and a list of the air-conditioning image acoustic data to be changed in the type corresponding to the switches is displayed. Display. Then, the instruction frame appearing in the list is moved by operating the up / down scroll switches 211c, 211d or 221c, 221d, and the selection switch 211e is positioned in a state where the instruction frame is positioned on the name of the air-conditioning image acoustic data to be selected. Touch to operate. As a result, the list is closed in such a manner that the air-conditioning image acoustic data having the name where the instruction frame is located is selected. In this state, by touching the decision switch 211h or 221h, the selected air-conditioning image acoustic data is set in association with each other. That is, the table of FIG. 5 stored in the HDD 200H is rewritten. Note that the screens of FIGS. 7A and 7B can be switched by touching the touch switches 211f and 221f. Further, by touching the initial setting switches 211g and 221g, the selection content is changed to the default setting. In the present embodiment, rewriting to the HDD 200H is performed mainly by the control unit of the navigation device 200 based on the touch operation of the display device 210. That is, the control unit of the navigation device 200 functions as air conditioning image acoustic data rewriting means. Note that music data stored in the HDD 200H by the user may be selected as the air-conditioning image sound data.

  And in the vehicle-mounted air conditioning system 1 of this embodiment, if an air conditioning output is started in the state in which the auditory air conditioning execution switch 150 is turned on, the air conditioning ECU 100 will set the current air conditioning output state based on the setting contents. The air-conditioning image sound data stored in the table of FIG. 5 is selected, and the selected air-conditioning image sound data is reproduced and output in the vehicle interior. That is, the air conditioning ECU 100 obtains the corresponding air conditioning image acoustic data from the HDD 200H based on whether the current air conditioning output state is the heating output state or the cooling output state, whether the output level is high or low, and the like. In addition to the selection, a reproduction output request signal is transmitted to the audio controller 600 so as to reproduce and output the selected air-conditioning image sound data into the vehicle interior. When the audio controller 600 receives the reproduction output request signal, the audio controller 600 transmits a reproduction output instruction signal to the audio driving unit 630 based on the received reproduction output request signal. Finally, the selected air conditioning image is output from the speaker 635. Acoustic data is output as an auditory air conditioning output sound.

  More specifically, the processing of the air conditioning ECU 100 is performed by the CPU executing the air conditioning control program PG (FIG. 2) stored in the ROM in the air conditioning ECU 100. That is, the air conditioning ECU 100 is air conditioning image acoustic data selection means, and the audio controller 600 and the audio drive unit 630 to be controlled function as air conditioning image acoustic data reproduction output means. Hereinafter, the processing flow of the air conditioning control program PG will be described with reference to the flowcharts of FIGS.

  First, in S1, the air conditioning ECU calculates and sets the air conditioning control state. Specifically, control parameters relating to blowout temperature control, air volume control, inside air / outside air intake switching control, and outlet switching control are calculated. In S2, the operation state of the auditory air conditioning execution switch 150 is determined. If the auditory air conditioning execution switch 150 is off, the process proceeds to S9 and normal air conditioning control is started. On the other hand, if the auditory air conditioning execution switch 150 is on, the process proceeds to S3.

  In S3, it is determined from the air conditioning control state calculated and set in S1 whether the executed air conditioning output is cooling or heating. When it is cooling, it progresses to S4, and when it is heating, it progresses to S5. And in S4 and S5, while selecting the air-conditioning image sound data to reproduce and output, the output setting state is determined. Specifically, the process of the flow shown in FIG. 9 is executed.

  That is, first, in S11, it is determined whether or not the audio apparatus is outputting music or program broadcast. If the output is in progress, the process proceeds to S12, and the sound effect set in the table of FIG. 5 is selected (the sound effect corresponding to cooling when cooling, the sound effect corresponding to heating when heating). Subsequently, in S13, the output volume currently being played back is acquired, and in S14, the playback volume of the sound effect is set based on the acquired output volume (auditory air conditioning output sound listening assistance means). That is, in order to ensure that the sound effect can be heard even when the current music or program broadcast is output, the larger the current output volume is, the larger the sound effect playback sound is set, and conversely the current output sound volume is low. Set the playback volume of the sound effect to a lower value. Then, returning to FIG. 8, the process proceeds to S6.

  On the other hand, if it is determined in S11 that the audio device is not outputting, the process proceeds to S15, and the sound effect set in the table of FIG. 5 (the sound effect corresponding to the cooling when cooling, the sound effect when heating) Sound effects corresponding to heating) and music, ie composite sound. Subsequently, in S16, the sound volume of the sound effect and music is set to a predetermined volume. Then, returning to FIG. 8, the process proceeds to S6.

  Returning to FIG. In S6 of FIG. 8, the air conditioning output state set in S1 is corrected in the direction of decreasing the air conditioning output level (air conditioning output state correcting means). Specifically, as shown in FIG. 10, correction is performed simultaneously so that the temperature of the air-conditioning airflow is made closer to the temperature detected by the internal air temperature sensor 121 and correction of reducing the amount of air-conditioning airflow is reduced. Only one of these may be corrected. In the present embodiment, the required blowing temperature (target blowing temperature) TAO is recalculated after the blowing set temperature is brought close to the current vehicle interior temperature by a certain ratio (for example, 80%). In this case, the blown air volume is also changed in the direction of lowering the air conditioning output level based on the recalculation result of the necessary blown temperature TAO.

  In S7, air conditioning output is started based on the air conditioning output state corrected in S6. In S8, sound output, that is, reproduction output of the air-conditioning image sound data is started based on the sound output setting in S4 or S5.

  Thus, the in-vehicle sound, which has been conventionally recognized as having a hindrance to the in-vehicle air conditioning, can function as an assisting function for in-vehicle air conditioning, and the air-conditioning output effect felt by the user can be increased compared to the conventional case. In other words, at the time of air conditioning output, by simultaneously reproducing and outputting the air conditioning image acoustic data, the user listens not only to the physical air conditioning effect by the air conditioning airflow, but also to the reproduction output sound (auditory air conditioning output sound) of the air conditioning image acoustic data. With this, you can get the same image as the physical air conditioning effect and feel the psychological air conditioning effect.

  Moreover, since only the sound effect is output as the auditory air conditioning output sound at the time of audio output, it does not greatly hinder the viewing of the music or program broadcast being played.

  As mentioned above, although embodiment of this invention was described, these are only illustrations to the last, and this invention is not limited to these, A various change is possible unless it deviates from the meaning of a claim. .

  For example, the selection of the air-conditioning image acoustic data can be performed as follows.

  The HDD 200H stores the air-conditioning image acoustic data in a form corresponding to the temperature difference between the air-conditioning air flow setting temperature and the detected temperature of the internal air temperature sensor 121 in the cooling output state, and the air-conditioning image acoustic data selection means 100 After the temperature difference in the cooling output state is specified, the air-conditioning image acoustic data that increases the cool feeling as the specified temperature difference increases can be selected. As a result, the air-conditioning image acoustic data having a cooler image is reproduced and output as the vehicle interior is hot and it is desired to exert a greater cooling capacity, so that the user can feel cooler more quickly.

  In addition, the HDD 200H stores the air-conditioning image acoustic data in association with the temperature difference between the air-conditioning air flow setting temperature and the detected temperature of the internal air temperature sensor 121 in the heating output state, and the air-conditioning image acoustic data selection The means 100 can select the air-conditioning image acoustic data that increases the sense of warmth as the specified temperature difference increases after specifying the temperature difference in the heating output state. As a result, the warmer image of the air-conditioning image acoustic data is reproduced and outputted as the passenger compartment is colder and the heating capacity is desired to be exhibited more greatly, so that the user can feel the warmth more quickly.

  In this case, the HDD 200H stores a plurality of air-conditioning image acoustic data corresponding to the cooling output state and the heating output state, and each of the stored air-conditioning image acoustic data includes a contribution level (hereinafter referred to as an air conditioning effect). , Also referred to as the air conditioning contribution level). Then, depending on the air conditioning output level determined from the setting content of the air conditioning output state, such as the temperature difference between the air conditioning airflow blowing set temperature (or required blowing temperature) and the temperature detected by the internal air temperature sensor 121, and the amount of blown air. It is possible to select air conditioning image acoustic data having a high air conditioning contribution level. That is, when the air conditioning output level is high, the air conditioning image acoustic data with a high air conditioning contribution level can be selected, and when the air conditioning output level is low, the air conditioning image acoustic data with a low air conditioning contribution level can be selected. Thereby, appropriate air-conditioning image sound data according to the air-conditioning output level can be reproduced and output. In particular, when the air conditioning output level is high, the air conditioning state desired by the user is far from the current state, so by selecting and playing back the air conditioning image acoustic data with a higher air conditioning contribution level, the user can You can feel the desired warmth quickly.

  As described above, the level of the air conditioning contribution level may be determined in advance for each type (sound type) instead of being determined for each air conditioning image acoustic data. In this case, the HDD 200H stores air-conditioning image acoustic data associated with a plurality of types, and the air-conditioning contribution level is determined in advance for each of the stored types. Then, depending on the air conditioning output level determined from the setting content of the air conditioning output state, such as the temperature difference between the air conditioning airflow blowing set temperature (or required blowing temperature) and the temperature detected by the internal air temperature sensor 121, and the amount of blown air. The air conditioning image acoustic data of a type having a high air conditioning contribution level can be selected. That is, when the air conditioning output level is high, a type with a high air conditioning contribution level can be selected, and when the air conditioning output level is low, a type with a low air conditioning contribution level can be selected.

  Next, it is possible to do the following with respect to hearing aid for hearing air conditioning output sound.

  In the above embodiment, the hearing air conditioning output sound listening assistance is performed by setting the reproduction volume of the air conditioning image acoustic data as in S14 and S16 of FIG. 9, but other methods may be used. For example, instead of changing the entire sound range of the reproduction volume, the high sound range and the low sound range may be changed relative to the middle sound range therebetween. Moreover, you may use the noise canceling apparatus which cancels noises, such as the blowing sound of an air-conditioning airflow.

  Also, the hearing assistance level of the auditory air conditioning output sound can be changed based on the setting contents of the air conditioning output state. In the vehicle air conditioning, as the air conditioning output level increases, noise such as a blowing sound increases and it becomes difficult to hear the auditory air conditioning output sound. However, the magnitude of such noise can be determined from the setting contents of the air conditioning output state such as the magnitude of the blown air volume. According to the above configuration, the hearing assistance level of the auditory air conditioning output sound can be changed in consideration of the magnitude of noise that can be determined from the air conditioning output state. This ensures that the user can hear the auditory air conditioning output sound.

  Specifically, as shown in FIG. 11, listening to the audio-acoustic output sound can be assisted by setting the listening assistance level to be larger as the amount of air-conditioning airflow is larger. Further, by setting the listening assistance level (for example, the reproduction volume of the air-conditioning image acoustic data) to be larger as the temperature difference between the air-conditioning air flow setting temperature (or the required air-flow temperature) and the detected temperature of the internal air temperature sensor 121 is larger. The hearing of the auditory air conditioning output sound may be assisted. According to these configurations, it is easy to change the listening assistance level by using the air conditioning output setting parameters such as the temperature difference and the blown air volume used for air conditioning control.

  Moreover, regarding the selection of the above-described air-conditioning image sound data, it is possible to use the hearing assistance level of the auditory air-conditioning output sound as follows.

  In other words, the air conditioning image acoustic data or the type (of the air conditioning image acoustic data) can be selected based on the hearing assistance level of the auditory air conditioning output sound and the air conditioning output level determined from the setting content of the air conditioning output state. . Thereby, it is possible to select air conditioning image acoustic data having a more appropriate air conditioning contribution level. For example, as shown in FIG. 12, the air conditioning contribution level based on the temperature difference between the air conditioning airflow blowing set temperature (or the necessary air blowing temperature) and the detected temperature of the internal air temperature sensor 121 and the reproduction volume of the air conditioning image acoustic data. It is possible to switch between a higher type and a lower type. In the case of FIG. 12, the playback volume of the air-conditioning image acoustic data in which the threshold value (type switching threshold value) for switching between music that is a type with a high air-conditioning contribution level and sound effects that are a low type is a hearing assistance level for the auditory air-conditioning output sound. It changes dynamically according to the. Since the air conditioning effect by the auditory air conditioning output sound increases as the playback volume increases, in FIG. 12, the type switching threshold is set so that the type with a lower air conditioning contribution level is selected as the listening assistance level increases. It is. Note that the air-conditioning image sound data or its type can be selected based on the blown air volume and the reproduction volume of the air-conditioning image sound data.

  Further, the correction of the air conditioning output can be performed as follows.

  For example, it is assumed that the air conditioning output is corrected on the assumption that the air conditioning image acoustic data is selected by any one of the various methods for selecting the air conditioning image acoustic data as described above. In this case, first, before selecting the air conditioning image acoustic data, the air conditioning contribution level described above is set in advance for each air conditioning image acoustic data (or the type) to be selected. Then, when the air-conditioning image acoustic data to be reproduced and output is selected, the air-conditioning output state is changed based on the contribution level of the air-conditioning image acoustic data. In other words, the higher the air conditioning contribution level of the selected air conditioning image acoustic data, the more the air conditioning output is corrected, and conversely, the lower the air conditioning contribution level of the selected air conditioning image acoustic data, the more the air conditioning output. The correction is performed to reduce it to a small extent. As a result, when air conditioning image acoustic data with a high air conditioning contribution level is selected, a greater air conditioning effect can be expected. Therefore, the air conditioning output level due to the air conditioning airflow can be greatly reduced by that amount to save energy. Even if air conditioning image acoustic data having a low air conditioning contribution level is selected, energy saving corresponding to the air conditioning image acoustic data can be achieved.

  In the case of the configuration for correcting the air conditioning output, the air conditioning image acoustic data is stored in the HDD 200H in association with the correction content, and the selected air conditioning image data is selected when the reproduced air conditioning image acoustic data is selected. It is possible to read out the correction content corresponding to the image sound data and correct the air conditioning output state based on the content.

  In this case, the correction contents are not associated with each other and stored in the HDD 200H for each of the plurality of air conditioning image acoustic data having different air conditioning contribution levels, but are classified according to the level of the air conditioning contribution level and correspond to these types. The correction content may be set in the HDD 200H. For example, as shown in FIG. 15, as the classification based on the level of the air conditioning contribution level, a first type and a second type having a higher air conditioning contribution level can be provided. In the case of FIG. 15, the correction contents of the first type and the second type are defined in common in the heating output state and the cooling output state. For this reason, when correcting the air conditioning output, without determining whether the current air conditioning output state is the heating output state or the cooling output state, only by determining the type of the selected air conditioning image acoustic data, Since the correction content of the air conditioning output state can be grasped, the correction process is simplified.

  Moreover, in the structure which correct | amends an air-conditioning output, the correction amount of an air-conditioning output can be enlarged, so that the listening assistance level of an auditory air-conditioning output sound becomes high. For example, when switching the type of the air-conditioning image acoustic data as shown in FIG. 12, as shown in FIG. 13, the correction amount of the air-conditioning output (target blowing temperature and blowing amount) is increased as the reproduction volume of the air-conditioning image acoustic data is increased. Can be great. However, in the case of FIG. 12, when the reproduction volume (listening assistance level) of the air-conditioning image acoustic data increases, the type (sound effect) with a low air-conditioning contribution level is switched to a higher type (music). For this reason, although it is determined that the correction amount of the air conditioning output becomes larger as the listening assistance level becomes higher, the increase rate of the correction amount is reduced at the boundary of the type switching threshold (type switching threshold point). That is, since the air conditioning effect by the auditory air conditioning output sound is significantly increased by switching the type of the air conditioning image acoustic data, the correction amount can be increased by the increment. Thereby, more effective energy saving can be achieved.

  The air conditioning contribution level described above may be set by the user.

  For example, as shown in FIG. 14, out of all the data registered as the air conditioning image acoustic data, the first acoustic data (sound 1 in the figure) and the second acoustic data having a higher air conditioning contribution level (see FIG. 14). The user may be able to arbitrarily set the sound 2) inside. Specifically, based on an operation on a predetermined operation unit provided in the display device 210, an air conditioning image acoustic data setting change screen 230 shown in FIG. 14 is displayed on the screen of the display device 210, and the screen is displayed. It changes in the form which selects one each for the sound 1 and the sound 2 from all the air-conditioning image sound data from the upper touch switch 231 (231a-231h). In the case of FIG. 14, from the screen 230, first, the touch switches 231a and 231b are touch-operated to display a list of air conditioning image sound data that can be set for the contribution level (to the air conditioning effect) corresponding to these switches. Display. Note that the list of air-conditioning image acoustic data here has the same contents regardless of the contribution level. Then, the instruction frames appearing in the list are moved by operating the up / down scroll switches 231c and 231d, and the selection switch 231e is touch-operated in a state where the instruction frame is positioned on the name of the air-conditioning image acoustic data to be selected. . As a result, the list is closed in such a manner that the air-conditioning image acoustic data having the name where the instruction frame is located is selected. In this state, by touching the determination switch 231h, the selected air-conditioning image acoustic data is set in a form associated with each type. That is, the table of FIG. 5 stored in the HDD 200H is rewritten. The touch switch 231f switches between a cooling output state setting screen and a heating output state setting screen. Further, the selection content is changed to the default setting by touching the initial setting switch 231g.

  In addition, the setting of the reproduction volume of the air-conditioning image acoustic data can be performed as follows.

  For example, the setting of the reproduction volume of the air-conditioning image acoustic data can be performed based on the setting contents of the air-conditioning output state, in particular, the amount of airflow of the air-conditioning airflow. Specifically, the playback volume can be set to increase as the blowing air volume increases. As a result, the reproduction volume of the air-conditioning image acoustic data can be set in consideration of noise generated with the air-conditioning output so that the user can hear the reproduction sound of the air-conditioning image acoustic data (auditory air-conditioning output sound). . However, if the user cannot hear it at all, the air conditioning effect cannot be obtained. On the other hand, if the sound is too loud, the user feels uncomfortable. Therefore, as shown in FIG. Set the upper limit and lower limit for the playback volume of the acoustic data, and prohibit any change beyond that. The upper limit value and the lower limit value are determined within a range between the maximum volume setting and the minimum volume setting of the audio when the air-conditioning image sound data is reproduced and output from the audio driving unit 630.

  Also, the setting of the reproduction volume of the air-conditioning image acoustic data can be set based on the setting content of the volume adjustment operation unit 641. Specifically, it can be fixedly determined as a predetermined ratio (for example, 80%) of the volume setting value by the volume adjustment operation unit 641. In this case, when the volume adjustment operation unit 641 is set to the no volume state, the playback volume of the air-conditioning image acoustic data is also set to no volume so that the user intention is given priority.
