The integrated control device 5A learns the relationship with (on or off), and the integrated control device 5A sets the comfort level within the comfort range based on the relationship between the comfort level learned in the learning unit 51 and the operation of the air conditioning operation panel 3. An instruction is given to the air conditioning control device 4. As a result, the air conditioning control device 4 integrates the air temperature, the ratio of outside air introduction and inside air circulation, the amount of air blown, the air blowing mode, or the on / off of the refrigeration cycle so that the comfort level becomes a preset comfort range. Can be instructed to.

[Embodiment 3]
As shown in FIG. 6, in the vehicle air-conditioning system 1B according to the third embodiment of the present invention, in the vehicle air-conditioning system 1B according to the above-described first or second embodiment of the present invention, the integrated control device 5B has a correction unit 52. Including. The correction unit 52 corrects the comfort level set in advance based on the operation of the air conditioning operation panel 3 when the comfort level is in the preset comfort range and the air conditioning operation panel 3 is operated. In this way, when the comfort level is in the preset comfort range and the air conditioning operation panel 3 is operated, it is an individual to correct the comfort range based on the operation of the air conditioning operation panel 3. This is because there is a difference and the preset comfort range (default comfort range) may not be comfortable for the user of the vehicle 100.

Therefore, for example, when the air conditioning operation panel 3 is operated so that the temperature setting becomes lower when the comfort level is in the comfort range (default comfort range), the temperature setting becomes lower than the default comfort range. Correct to. Further, for example, when the air conditioning operation panel 3 is operated so that the temperature setting becomes high when the comfort level is in the comfort range (default), the comfort range is corrected to be higher than the default comfort range. The correction of the comfort range may extend the comfort range, but may change (shift) the comfort range.

As shown in FIG. 7, in the vehicle air-conditioning system 1B according to the third embodiment of the present invention described above, it is determined whether or not the comfort level is within the comfort range (step S21).

Associate the conversation with the operation to raise the set temperature (learning). Further, in the learning unit 55, when the air conditioning operation panel 3 is operated so that the set temperature becomes low within a predetermined time after the conversation of the occupant including words such as hot, the conversation including words such as hot is included. Is associated with the operation of lowering the set temperature (learning).

Further, as shown in FIG. 10, in the vehicle air-conditioning system 1C according to the fourth embodiment of the present invention, it is determined whether or not the comfort level is within the comfort range (step S41). When the comfort level is within the comfort range (step S41: Yes), it is determined whether or not there is a conversation including a specific action or a specific word (step S42). When it is determined in step S42 that there is a conversation containing a specific action and a specific word (step S42: Yes), a preset comfort range (default) is set based on the specific action and the conversation including the specific word. Comfort range) is corrected (step S43).

For example, when the movement of touching the arm or thigh is associated with the operation of raising the set temperature, if the movement of the arm or thigh is touched while the comfort level is within the comfort range, the comfort range is higher than the default comfort range. It is corrected so that it becomes. For example, when the action of wiping sweat and the action of lowering the set temperature are related, if the sweat is wiped while the comfort level is in the comfort range, the comfort range is corrected to be lower than the default comfort range. The default.

Also, for example, when a conversation containing words such as cold is associated with an operation of raising the set temperature, it is comfortable to have a conversation containing words such as cold while the comfort level is within the comfortable range. The range is corrected to be higher than the default rotation range. Also, for example, when a conversation containing words such as hot is associated with an operation of lowering the set temperature, it is comfortable to have a conversation containing words such as hot while the comfort level is within the comfortable range. The range is corrected to be lower than the default rotation range.

According to the vehicle air-conditioning system 1C according to the fourth embodiment of the present invention described above, when the air-conditioning operation panel 3 is operated within a predetermined time after the acquisition of subjective information including the movement or conversation of the occupant.
