A compressor on / off determining means 68 for controlling the temperature, a display calculating means 6 for instructing a display device 73 to input a set temperature Ts from the room temperature setting device 53 together with the temperature control command value.
The present invention relates to a vehicle air conditioner provided with a control device including a control device 9 and the operation of this part is the same as that of a conventional device, and therefore description thereof will be omitted.

In the present embodiment shown in FIG. 1, in addition to the above apparatus, the room temperature setting device 53 and the temperature control command value calculating means 7 are provided.
2 is provided between the outside air temperature sensor 43 and the outside air temperature Ta
Is input and the vehicle interior temperature Ti is input from the vehicle interior temperature sensor 44, and the set temperature Ts output from the room temperature setting device 53 is converted into the control set temperature Tss and output to the temperature adjustment command value calculation means 72. The operation control device 80 is provided.

Regarding the learning operation control device 80, the selection output means 81, the ignition (IG) switch 82, the comparison means 83, the setting means 84, the set temperature learning storage means 85, and the learning which will be described in detail below are provided. Map 8
6, the filter setting means 88, and the control set temperature determining means 89.

The selection output means 81 selectively outputs the set temperature Ts inputted from the room temperature setting device 53 under a predetermined condition. As the predetermined conditions, the vehicle interior temperature sensor 44 detects the indoor temperature Ti and IG. Switch 82 (1,2
ON / OFF signals are input from the OFF signal in each stage and the one that outputs the ON signal in three stages).

Therefore, the selection output means 81 causes the change amount ΔTi of the room temperature Ti to be changed every predetermined time (for example, 10 minutes).
(= Ti before 10 minutes-current Ti) is calculated, and when this is within a predetermined value (for example, 1 to 2 ° C.) (recognizing that the air conditioning inside the vehicle is in a stable state), and from the IG switch 82. The set temperature Ts when the off signal is received is selected and extracted as the learning value, and is output to the comparison means 83.

The reason why the selecting means 81 is provided will be described below. When the car engine is started and the air conditioner is started, it is first operated with maximum cooling (heating) capacity (pull-down operation), and when the room temperature reaches Ts, the A / M damper 18 is controlled and the air conditioner is controlled. The capacity of the machine is adjusted and the room temperature is maintained at Ts (capacity control operation). However, since the change of Ts needs to be performed after the capacity control operation is stable, the selecting means 81 controls the capacity control in a stable state. It is provided to output only Ts during operation to the storage means 83.

It should be noted that, for a predetermined time (for example, 10 minutes), the room temperature fluctuates when there is a disturbance during running in a stable state, but it is considered that the room temperature will be stable again within 10 minutes, and a predetermined value (for example, 1 to 2). ℃) is determined from the fact that the fluctuation of room temperature is considered to be within this predetermined value even if there is a disturbance.

In the comparing means 83, a predetermined temperature (hereinafter, abbreviated as indoor air conditioning reference temperature, for example, 25 ° C.) is set as a reference value (maximum common divisor air conditioning temperature at which most passengers feel comfortable) from the setting means 84 in the comparing means 83. ) Is input, and the comparison means 83 uses the set temperature Ts and the indoor air-conditioning reference temperature (for example, 25
Deviation A (hereinafter referred to as a learning correction value. A = Ts −
25) is calculated and output to the set temperature learning storage means 85.

Here, the reason why the comparing means 83 outputs the deviation A instead of Ts is to reduce the number of digits of the numerical value and to efficiently use the storage device of the set temperature learning storage means 85. is there.

The set temperature learning storage means 85 is a means for storing Ts in association with the running condition. The detected value Ti of the vehicle interior temperature sensor 44 and the detected value Ta of the outside air temperature sensor 43 are input to this, and the stored value is stored. The storage unit is provided with a two-dimensional learning map 86 based on the vehicle interior temperature Ti and the outside air temperature Ta as shown in FIG. 2, and 49 addresses 87 are set at intervals of 10 degrees, for example.

Therefore, the set temperature learning storage means 85 is
When the learning correction value A input from the comparison means 83 is received, the outside air temperature sensor 43 and the vehicle interior temperature sensor 4
4 is written and stored in the address 87 of the learning map 86 corresponding to the vehicle interior temperature Ti and the outside air temperature Ta input from the No. 4 vehicle.

The above writing is performed by the following (1),
It is performed as in (2). (1) When a new learning correction value A'is input to the address 87 where the learning correction value A has already been written, the old one is erased and the latest one is written. This is because the numerical value stored in each address 87 of the learning map 86 is updated. (2) When the learning correction value A = O (set temperature = indoor air-conditioning reference temperature, for example, 25 ° C.), writing is not performed. This is because A = 0 is output to the control set temperature determining means 89 described later from the address 87 in which the A value is not written.

A predetermined filter is input from the filter setting means 88 to the set temperature learning storage means 85, and the learning correction value A input from the comparison means 83 is applied with a predetermined filter. , Written in the learning map 86. This is the address 87 because the driving conditions of the car change.
This is to prevent the set temperature Ts from changing suddenly when the temperature changes.

The contents of the predetermined filter are the abnormal value exclusion process (1) and the smoothing process (2) described below. (1) In the abnormal value exclusion processing, the learning correction value A to be written is limited in order to avoid a sudden change in the vehicle interior temperature.
For example, A value exceeding ± 2 ° C. is not written. (2) In the smoothing process, the learning correction value A between the adjacent addresses 87 of the learning map 86 is used in order to avoid a sudden change in the vehicle interior temperature.
Since the difference is within a predetermined value (for example, 1 ° C.), the received A value is removed or corrected and written.

In the control set temperature determining means 89, the set temperature Ts from the room temperature setter 53, the outside air temperature Ta from the outside air temperature sensor 43, and the vehicle interior temperature T from the vehicle interior temperature sensor 44.
i has been entered. The control set temperature determining means 89 calls the learning correction value A written in the address 87 of the learning map 86 corresponding to the received outside air temperature Ta and vehicle interior temperature Ti, and receives the set temperature T received as follows.
s is corrected by the A value to calculate the control set temperature Tss, which is output to the temperature adjustment command value calculation means 72.

The above correction is performed as follows. (1) Set temperature Ts = indoor air conditioning reference temperature (for example, 25
Cs), Tss = Ts + A = Ts' (2) The set temperature Ts is the indoor air conditioning reference temperature (for example, 25
Other than (° C.), Tss = Ts This is because the set temperature is set to the passenger's favorite temperature.

As described above, in the present embodiment, the deviation between the set temperature Ts set according to the occupant's individual preferences (cold, hot) and the indoor air-conditioning reference temperature (for example, 25 ° C.) is defined as the vehicle running condition ( In the example, the learning correction value A is stored in correspondence with the indoor temperature and the outside air temperature, and when the set temperature Ts is other than 25 ° C., normal temperature control is performed and the set temperature Ts is 25 ° C.
When, the set temperature Ts is set by the stored learning correction value A.
Assuming that the temperature setting according to the individual preference of the occupant can be performed by obtaining the control set temperature Tss in which the temperature is corrected and performing the temperature control (hereinafter referred to as learning temperature control, the operation by this control is referred to as learning operation) There is. Therefore, in the present embodiment, the learning operation control device 80 is interposed between the conventional room temperature setting device 53 and the temperature control command value calculating means 72.

A second embodiment of the invention is shown in FIG. In the present embodiment shown in FIG. 3, the solar radiation sensor 42 inputs the detected solar radiation amount to the control set temperature determining means 89 'and the set temperature learning storage means 85', respectively. In the storage section of the means 85 ',
Although illustration is omitted, a three-dimensional learning map 86 ′ based on the vehicle interior temperature, the outside air temperature, and the amount of solar radiation is provided. Others are the same as those in the first embodiment.

In the first embodiment, two elements of the vehicle interior temperature and the outside air temperature are extracted from the driving conditions of the vehicle, and the learning correction value A is written in the two-dimensional learning map 86 based on the vehicle interior temperature Ti and the outside air temperature Ta. While the set temperature is corrected by the stored learning correction value A to control the learning temperature, in this embodiment, the amount of solar radiation is added to this, and the learning correction value A is added to the vehicle interior temperature, the outside air temperature, and the amount of solar radiation. 3D learning map 86 '
Can be written on. Therefore, the set temperature can be corrected more finely, and the comfort of the learning temperature control can be further improved.

A third embodiment of the invention is shown in FIG. In the present embodiment shown in FIG. 4, reference numeral 90 denotes a learning operation switch arranged on the control operation panel 46, which is operated when an occupant wants to start learning operation, and an ON / OFF signal of the learning operation switch is used to determine the control temperature setting means. 89 and the display calculation means 69.

The control set temperature determining means 89 operates only when an ON signal is received from the learning operation switch 90. That is, the control set temperature determining means 89 uses the learning correction value A stored in advance in the set temperature learning storage device 85 in accordance with the traveling conditions of the vehicle (in the illustrated example, the vehicle interior temperature and the outside air temperature). Air conditioning reference temperature (eg 25
C) is corrected to calculate a control set temperature Tss [Tss = room reference temperature (for example, 25 ° C.) + A], and the calculated temperature is output to the temperature adjustment command value calculation means 72.

When the display operation means 69 receives an ON signal from the learning operation switch 90, the room temperature setting device 53.
It is determined that the indoor air conditioning reference temperature (eg, 25 ° C.) is displayed regardless of the set temperature received from the temperature display 74 of the display device 73 is switched from the set temperature to the indoor reference temperature (eg, 25 ° C.).

Thus, the occupant learns the driving switch 90.
When is turned on, the indoor air-conditioning reference temperature (for example, 25 ° C.) is displayed on the display device 73 regardless of the set temperature at that time, and the indoor air-conditioning reference temperature (for example, 25 ° C.) is set as the traveling condition. Correspondingly, temperature control (learning temperature control) is performed by the control set temperature Tss corrected by the learning correction value A stored in advance. When the learning operation switch 90 is off, the temperature is normally controlled by the set temperature Ts.

In the first and second embodiments, since the learning temperature control is automatically entered, there is a problem that it is difficult for the occupant to judge whether the temperature control is in the normal temperature control or in the learning temperature control, but in the third embodiment. Since the learning operation switch 90 is added and the occupant can select which one of the driving operations, the driver does not hesitate to make a decision. Other configurations and operations are similar to those of the first embodiment shown in FIG. Although illustration and description are omitted, similar additions can be made to the second embodiment shown in FIG.

A fourth embodiment of the invention is shown in FIG. In this embodiment, the display method on the display device 73 in the third embodiment is improved, and the control system is the same as that in FIG.

The display calculation means 69 'is the learning operation switch 9
When the ON signal is received from 0, the indoor air conditioning reference temperature (for example, 25 ° C.) is displayed regardless of the set temperature received from the room temperature setting device 53, and the display indicating that the learning operation is in progress is displayed. Then, the temperature display 74 of the display device 73 ′ displays the set temperature from the indoor air conditioning reference temperature (for example, 25
At the same time, the display indicating that the learning operation is being performed, for example, "learning" 76 is displayed. Note that neither of the temperature indications 74 of the display device 73 is displayed,
It is also possible to display only “learning” 76.

In the present embodiment, during the learning operation, a display indicating that the learning operation is in progress, for example, "learning" 76 is displayed on the display device 73, so that the occupant can easily determine whether the normal operation or the learning operation is in progress. I can know.
