2. Description of the Related Art Conventionally, an air conditioning controller for estimating the temperature sensation (warmness) of an occupant only from the skin temperature of the occupant and controlling the air conditioner based on the estimated temperature sensation has been proposed. It is known (Japanese Patent Laid-Open No. 1-229713). In addition, by estimating the comfort level of a person in the room and controlling the air conditioner based on this comfort level, it is possible to realize a more comfortable air conditioning and living environment in consideration of the indoor environment and the state of the person. A control device for an air conditioner is known (Japanese Patent Laid-Open No. 4-316947).

However, in the above conventional air conditioner control device, the same feeling of warmth and comfort is given to any of the states, and it is desired to make it warmer, cooler, or need more air volume. It was not possible to satisfy the individual preference of the user who uses the air conditioner that is unnecessary. Therefore, it is hard to say that it is an air conditioner that makes the user comfortable enough. It is possible to obtain a comfortable air-conditioning system that has been completed for the first time by performing control according to the user's preference, but the demands of such user's preference change delicately depending on the environmental conditions, and the level is uniquely set. The method of changing it is not enough, and it is necessary to adjust it in consideration of environmental conditions. However, in the past, there is no control device that performs control that matches the preference of the user in consideration of environmental conditions as described above, and the present preference is that the preference of the user for air conditioning is not sufficiently taken into consideration.

The present invention has been made to solve the above problems, and provides an air conditioner control device capable of performing control according to the user's preference in consideration of the user's preference. The purpose is to provide.

[0005]

In order to achieve the above object, the present invention provides an input means for inputting information on a user's preference for air conditioning using an air conditioner, and an environment surrounding the user. Detection means for detecting the condition,
Based on the ambient environment condition and the correction amount, a correction amount calculation means for calculating and storing a correction amount for making the air conditioning correspond to the user's preference based on the information on the preference and the ambient environment condition. And a control means for controlling the air conditioner by calculating the control amount of the air conditioner.

[0006]

When the user is uncomfortable with the current air-conditioning condition, the correction amount calculating means of the present invention detects the information about the air-conditioning preference of the user who uses the air-conditioning apparatus, which is input from the inputting means, and the detecting means. On the basis of the user's surrounding environmental conditions detected in step 1, the correction amount for making the air conditioning correspond to the user's preference is calculated, and at the same time the correction amount is stored. From the next time, when the detection unit detects the same environmental condition as when the correction amount is stored this time, the correction amount calculation unit automatically outputs the stored correction amount. Then, the control means calculates the control amount of the air conditioner based on the ambient environment condition of the user and the correction amount to control the air conditioner. As described above, according to the present invention, the air conditioning by the air conditioning apparatus is controlled so as to correspond to the preference of the user, so that the air conditioning according to the preference of the user can be performed. The information regarding the user's preference for air conditioning includes temperature, humidity, speed of air flow, and odor.

[0007]

As described above, according to the present invention, since the air conditioning by the air conditioner is controlled so as to correspond to the preference of the user, the air conditioning corresponding to the preference of the user is performed. The effect is obtained.

A pyranometer 11, an exterior thermometer 28 for measuring the temperature outside the vehicle, a preference input device 9 for inputting preference information indicating an occupant's preference for air conditioning, and a thermal sensation setter 12 for setting a thermal sensation value are connected. ing. The vehicle interior thermometer 27, the vehicle interior hygrometer 30, the pyranometer 11, and the vehicle exterior thermometer 2
Reference numeral 8 acts as a detection means for detecting the environmental conditions of the occupant.

As shown in FIG. 3, the preference input device 9 includes a button group 9A for inputting preference information for the temperature of the air flow supplied from the air conditioner, and a flow velocity (air volume) of the air flow supplied from the air conditioner. It is provided with a button group 9B and the like for inputting preference information regarding. Button group 9A is hot,
The button group 9B is composed of three buttons displayed as appropriate and cold, and the button group 9B is composed of three buttons displayed as strong, appropriate, and weak. When the occupant feels hot, the occupant is controlled to lower the temperature inside the vehicle by operating the button displayed as hot. Further, when the occupant feels that the air volume is strong, the air volume is controlled to be weakened by operating the button displayed as strong.

In the RAM having the backup function, as shown in FIG. 6, a three-dimensional map of the correction amount determined according to the vehicle room temperature and the amount of solar radiation is stored in advance. As for the map of the correction amount, two maps, a correction amount map for correcting the opening degree of the air mix damper 38 and a correction amount map for correcting the supply voltage of the blower 39 are defined, but only one is disclosed. did. Note that a map of the correction amount for correcting the target temperature sensation set by the temperature sensation setter 12 may be further provided.

FIG. 2 is a functional block diagram of the air-conditioning control device 14. The air-conditioning control device 14 detects the vehicle room temperature detected by the vehicle interior thermometer 27 and the vehicle interior detected by the vehicle interior hygrometer 30. It is provided with a measurement value capturing means 14A configured by a multiplexer for sequentially capturing the humidity, the amount of solar radiation detected by the pyranometer 11, and the outside air temperature detected by the vehicle exterior thermometer 28, that is, ambient environment conditions. The measured value acquisition means 14A is connected to the preference learning / correction amount calculation means 14B. The preference learning / correction amount calculation means 14B is for making the air conditioning correspond to the occupant's preference based on the ambient environment conditions captured by the measurement value capture means 14A and the occupant's preference information input by the preference input device 9. By calculating and storing the correction amount, the occupant's air conditioning preference is learned. Further, the measured value taking-in means 14A and the preference learning / correction amount calculating means 14B have the surrounding environment conditions taken in from the measured value taking means 14A, the correction amount and the thermal sensation calculated by the favorite learning / correction amount calculating means 14B. It is connected to an air conditioner controller 14C for controlling the air temperature and the air volume by controlling the opening of the air mix damper 38 of the air conditioner and the supply voltage to the blower 39 based on the temperature value set by the setter 12. ing.

Next, the control routine of the air conditioning controller 14 will be described. When an occupant gets on and turns on the switch of the air conditioner, the routines shown in FIGS. 4 and 5 are executed. FIG. 4 shows an interrupt routine executed by the occupant operating the button of the preference input device 9 when the occupant feels uncomfortable during air conditioning or when the current air conditioning does not match the occupant's preference. FIG. 5 shows a main routine for controlling the opening degree of the air mix tamper and the supply voltage to the blower 39 based on the calculated control amount.

When the occupant operates the button of the preference input device 9, an interrupt routine for learning the occupant's preference shown in FIG. 4 is started, and the preference information input from the preference input device 9 is fetched in step 100. . In the next step 102, the amount of solar radiation detected by the pyranometer 11 and the vehicle room temperature detected by the vehicle interior thermometer 27 are captured via the measurement value capturing means 14A. In step 104, based on the preference information input from the preference input device 9, two correction amounts, that is, a correction amount for the opening of the air mix damper 38 and a correction amount for the supply voltage of the blower are calculated to have a backup function. Set to the two-dimensional map stored in RAM. In this embodiment, the correction amount ΔZ is formed by forming a peak or a valley having a constant height and a constant width around the vehicle room temperature and the amount of solar radiation when the preference information is input.
Is set. When the air conditioner is used for the first time, this map has no peaks and valleys, and the correction amount output from the preference learning / correction amount calculation means 14B is 0.

The peak or valley of the correction amount calculated in this way is stored in the backup RAM in step 106 and returned to the main routine.

In the main routine shown in FIG. 5, the ambient temperature, the amount of solar radiation, the vehicle room temperature, the vehicle cabin humidity, and the target temperature sensation value set by the temperature sensation setter 12 are fetched in step 110, and the preference shown in FIG. The correction amount for the opening of the air mix damper 38 and the correction amount for the supply voltage of the blower calculated by the learning interruption routine are fetched. In the next step 114, the control amount for controlling the opening degree of the air mix damper 38 and the control amount for controlling the opening degree of the air mix damper 38 based on the outside air temperature, the solar radiation amount, the vehicle room temperature, the vehicle cabin humidity, the target temperature sensation value and the correction amount fetched in step 112. A control amount for controlling the supply voltage of the blower 39 is calculated. Then, in step 116, the opening degree of the air mix damper 38 and the supply voltage of the blower 39 are controlled based on this control amount. in this way,
Since the opening amount of the air mix damper 38 and the supply voltage of the blower 39 are controlled by calculating the correction amount according to the occupant's preference information, the air conditioning is controlled to suit the occupant's preference. In addition, this correction amount is R which has a backup function.
Since it is stored in the AM, once the correction amount is calculated and stored in accordance with the preference information, if the environment conditions change and the environment condition coincides with the environment condition at the time when the preference information is input again, the storage condition will change. The opening amount of the air mix damper 38 and the blower 39 are controlled so as to meet the occupant's tastes by the correction amount being set.

FIG. 7 shows changes in pleasantness and discomfort before and after the learning when the learning according to the preference is performed as described above.

As described above, according to the present embodiment, the measuring means for measuring the environmental conditions and the control means for controlling the air conditioner provided in the conventional vehicle air conditioner can be used as they are. As a result, in addition to the conventional control for keeping the temperature in the vehicle interior constant or the control for keeping the passenger's warm feeling constant, it is possible to efficiently and accurately perform the control considering the occupant's preference.

In the above embodiment, an example in which the correction amount is stored in the form of peaks and valleys has been described, but the shape representing this correction amount may be any shape and may be stored in the form of a slope. Further, in the present embodiment, the map of the correction amount is formed by the insolation amount and the vehicle room temperature, but the two-dimensional map using any one of the outside air temperature, the insolation amount, the vehicle room temperature and the cabin humidity, the outside air temperature and the insolation amount. ,
A three-dimensional map in which any two of the vehicle room temperature and the vehicle room humidity are combined may be used, and a map using the outside temperature, the amount of solar radiation, the vehicle room temperature and the vehicle room humidity, and a map using all of them may be used. In addition to the above, the map for storing the correction amount is also divided into two for the air mix damper opening and the blower in the present embodiment, but one map is used, and the air mix damper opening or the blower is used from that map. The correction amount may be obtained by using a formula or the like for converting into the supply voltage.

In the above embodiment, the temperature sensation setter 12 is used to set the target temperature sensation. However, the present invention is not limited to this, and the setter is a temperature setter for setting the target temperature. It may be.

Further, a map showing a correction amount according to the preference information is stored in a RAM having a backup function for each occupant and a map corresponding to the occupant is selected, or the correction amount according to the preference information is set. If the magnetic card or IC card is recorded every time and the magnetic card or the IC card is replaced every time the occupant who uses the vehicle is different, the air conditioning suitable for the occupant can be realized for each occupant or each vehicle. it can.

Further, when one map is used and the occupant is changed, the peaks and valleys of the map of the correction amounts stored so far are flattened, and all the correction amounts are set to 0, thereby easily resetting. By doing so, it is possible to carry out learning that reflects the new occupant's taste.

Furthermore, in the above, an example in which a map is used for learning the occupant's preference has been described, but this part may be configured by a neural network or the like.

Although an example in which the present invention is applied to a vehicle has been described above, the present invention is not limited to this, and is applicable to air conditioning of vehicles such as railroad cars, aircrafts, ships, and indoor air conditioning in building structures. Can also be applied.
