Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a learning control type air conditioner for a vehicle, which can reflect the preference of a driver (operator) in air conditioning control.

[0002]

2. Description of the Related Art In recent years, an air conditioner (hereinafter, abbreviated as an air conditioner) for controlling an air conditioning condition in a vehicle compartment has been widely used in automobiles. In addition to manual air conditioners in which the occupant manually adjusts the air-conditioning temperature and the amount of air blown out, automatic air-conditioners that automatically adjust the air-conditioning temperature and the amount of air blown according to the set temperature of the occupant are becoming popular. .

In such an automatic air conditioner, for example, the air conditioning temperature and the blown air volume are adjusted by a controller such as a computer based on the outside temperature and the inside temperature of the vehicle and the set temperature set by the occupant. Further, the air conditioning temperature is adjusted by adjusting the opening degree of the air mix damper, controlling the on / off of the compressor, and controlling the switching between the inside air circulation and the outside air introduction.

That is, in the memory portion of the controller, the opening of the air mix damper, the selection of ON / OFF of the compressor, the selection of the internal air circulation and the external air introduction, corresponding to the external temperature, the internal temperature and the set temperature, The control information relating to the blown air volume and the like is preset and stored by, for example, a map or a data table, and the controller uses the preset map or data based on the detected outside air temperature, inside air temperature, and the set temperature. By using a table or the like, the opening degree of the air mix damper, on / off selection of the compressor, inside / outside air selection, blown air volume, etc. are set, and these controls are performed.

Regarding the set temperature, for example, a reference temperature may be set in advance and the occupant may press the "UP switch" or "DOWN switch" to adjust the reference temperature. In this case, the occupant may press the "UP switch" to raise the set temperature and the "DOWN switch" to lower the set temperature. As a result, the air-conditioning state of the passenger compartment is automatically adjusted to the one according to the operation of the passenger.

[0006] By adjusting the set temperature in this way, it is possible to realize an air-conditioning state in the passenger compartment according to the individual preference of the occupant, but normally, the change of the set temperature according to the operation of the occupant is performed by, for example, the ignition. It is reset when the switch is switched from OFF to ON, and when the air conditioner control is started, the control is started with the preset reference temperature as the set temperature of the air conditioner.

Such a reference temperature is preset as a standard air-conditioning state with respect to the environmental conditions inside and outside the vehicle such as the outside temperature and the inside temperature. For example, FIG. 22 shows a temperature adjustment allocation diagram (temperature adjustment allocation diagram) showing the control contents of a conventional learning control type air conditioner for an automobile, in which the opening of the air mix damper, the blower air volume, the outlet Switching, inside / outside air switching, and compressor on / off control are set based on the inside temperature, the set temperature, and the outside temperature.

In FIG. 22, the control characteristic A of the opening degree of the air mix damper is set so as to correspond to the inside air temperature (room temperature).
A control characteristic B of the blower air amount, a control characteristic C of switching the outlet (foot / face switching), a control characteristic D of switching the inside / outside air, and a control characteristic E of turning the compressor on / off are shown. These show the case where the outside air temperature is the standard temperature (20 ° C) and the set temperature is the reference temperature (25 ° C). The opening of the air mix damper, the blower air volume, the outlet switching (foot face) Each of the control values (switching), inside / outside air switching, and on / off of the compressor correspond to the temperature adjustment command value (expressed by four digits in the figure) below the room temperature in FIG.

Each control amount with respect to the temperature adjustment command value is given as shown in the figure. Naturally, the opening degree of the air mix damper is made small or fully closed so that the air conditioning temperature becomes lower if the room temperature is higher, or Under this setting, the higher the room temperature, the larger the blower air volume. On the contrary, if the room temperature is low, the opening degree of the air mix damper is increased so that the air conditioning temperature is increased, and under this setting, the blower air volume is increased as the room temperature is lower.

Regarding the switching of the air outlets, when the room temperature is low and the opening degree of the air mix damper is large, the foot blowout increases, and when the room temperature rises and the opening degree of the air mix damper becomes small, the face blowout increases. The compressor is turned off when the room temperature is low and turned on when the room temperature is high. Further, the inside / outside air switching is switched to the outside air introduction when the room temperature is high and the room temperature is low when the room temperature is high.

By the way, the value at room temperature shown in FIG.
This is a case where the set temperature is the reference temperature (for example, 25 ° C) and the outside air temperature is the standard temperature (for example, 20 ° C), and the set temperature is changed from the reference temperature, or the outside air temperature is other than the standard temperature. Then, the room temperature value slides left and right in the figure by an amount corresponding to each scale of the set temperature and the outside air temperature in FIG.

For example, when the room temperature is 28 ° C., the set temperature is not changed, but when the outside air temperature is 30 ° C.,
On the scale of the outside air temperature in FIG. 22, the standard temperature (20 °
Among difference a only the scale of the room temperature in the same direction (FIG. 22 from C) to 30 ° C, place is moved to the right) T _R (28+
Each control amount is determined in a). Therefore, the higher the outside air temperature, the more each controlled variable is set as if the room temperature had risen.
If it is heated, weaken it. On the contrary, as the outside air temperature is lower, each control amount is set as if the room temperature was lower. When the air conditioner is cooling, the control amount is weakened, and when the air conditioner is heating, the control amount is strengthened. As a result, the outside air temperature is reflected in the air conditioning control.

Further, an example in which the set temperature is changed is explained.
To clarify, for example, the room temperature is 28 ° C and the outside air temperature is 30 °
When the temperature is C, the change to raise the set temperature by 1 ° C
Once performed, the scale of the set temperature in FIG.
Difference b from temperature (25 ° C) to 26 ° C
Location T where the bank was moved in the same direction (left in FIG. 22) _R
Each control amount is determined at (28 + a-b).

Therefore, the higher the set temperature,
Each control amount is set as if the room temperature became low, and weakens this when cooling, and strengthens it when heating. Conversely, the lower the set temperature,
Each control amount is set as if the room temperature had risen. When the air conditioner is cooling, the control amount is increased, and when the air conditioner is heating, the control amount is weakened. Thus, the air conditioning control is performed according to the set temperature such that the room temperature rises when the set temperature is raised and the room temperature falls when the set temperature is lowered.

When the air conditioning control is started, the set temperature is always started from the reference temperature, and the air conditioning control is also changed according to the change of the set temperature.

[0016]

By the way, in the above-mentioned conventional auto air conditioner for automobile, it is necessary to adjust the set temperature at the start of the air conditioner control if the air conditioner control based on the preset reference temperature is satisfactory. But not
Otherwise, the driver needs to adjust the set temperature to obtain his or her desired temperature condition.

That is, when the air conditioner control is started, the air conditioner control based on the reference temperature is started, and the reference temperature is preset as a standard air conditioning state with respect to the environmental conditions inside and outside the vehicle. Since the preferred air conditioning condition is different for each person, there are of course many passengers who are not satisfied with this standard air conditioning condition. When such a standard air conditioning control state is started, such an occupant must necessarily operate so as to obtain an air conditioning state of his or her preference, for example, by raising or lowering the set temperature.

By the way, considering the usage pattern of an automobile,
It is common for a specific driver or passenger to get on a vehicle, and there are many cases where only one specific driver always gets on the vehicle. If the feeling of the driver or the like in such a usage form does not conform to the standard air conditioning control based on the preset reference temperature, the driver or the like is forced to change the set temperature every time the engine is started, for example. By the way, even automatic air conditioners have not been fully automated.

Regarding such an automatic air conditioner, various techniques have been proposed in order to make it more convenient. For example, in Japanese Unexamined Patent Publication No. 4-243617 (first prior art), when an occupant manually operates a setting end switch when a desired air conditioning state is achieved, a vehicle detected by various sensors at the time of this operation is detected. The indoor and outdoor environmental conditions, engine operating conditions, and setting information of various operation switches are stored in the second storage means, and a plurality of data forming a data table stored in the first storage means are stored in the second storage. A new data table is generated by updating the optimum data using fuzzy inference based on the setting data stored in the means, and thereafter, the operation stored in the changed data table and the first storage means. A technique of controlling an air conditioner based on a processing program is disclosed.

Further, Japanese Patent Laid-Open No. 5-77634 (second
In the prior art), in a vehicle air conditioner in which a blower voltage is set by fuzzy reasoning with temperature deviation between the inside temperature and the set temperature, the outside temperature, and the amount of solar radiation as input conditions, the outside temperature is set to the outside temperature. Uses 6 types of fuzzy rules set according to corresponding midwinter, winter, spring-autumn, spring-summer, summer, and mid-summer, and sufficiently reflects the set temperature set by the operation of the passenger to the blower voltage setting. As described above, a technique for calculating the temperature deviation is disclosed.

However, in the above-mentioned first conventional technique,
By updating the data table, the driver's preference will be reflected in the air conditioner control, and the auto air conditioner can be made more convenient. However, update the data table by changing each of the multiple data that composes this. Therefore, the update of this data table will be a large scale. In addition, since it is necessary to operate the setting end switch when the desired air conditioning condition is realized,
This can be tricky in some cases.

In both the first and second prior arts, since the air conditioner is controlled by utilizing the complex fuzzy inference using a large number of parameters, a large number of sensors for control are required, and A high level of computer capacity and memory capacity is required. Second
In the conventional technique, since only the blower voltage is adjusted, it is not always possible to obtain the optimum air conditioning state for the occupant, and it is necessary to simultaneously control other various air conditioning elements.

The present invention was devised in view of the above-mentioned problems, and while it can be constructed at a low cost with a simple structure, it learns the driver's preference and surely reflects this in the air conditioner control. It is an object of the present invention to provide a learning control type air conditioner for a vehicle, which can realize the air conditioner control desired by the driver with a slight air conditioner setting operation.

That is, in the temperature adjustment command value computing means 23, the room temperature value T _R detected by the room temperature sensor 11, the outside air temperature value T _OUT detected by the outside air temperature sensor 12, and the set temperature storage means 22 are stored. The temperature adjustment command value F is calculated based on the control set temperature T _S , for example, by the following equation. F = f ₁ (T _R ) + f ₂ (T _OUT ) + f ₃ (T _S ) ... (1) However, here, f ₁ and f ₃ are as shown on the corresponding scale of FIG. Each is a linear function, and f ₂ is given as a non-linear function as shown in the corresponding scale of FIG.

The sensor values (that is, the room temperature value T _R and the outside air temperature value T _OUT ) and the control set temperature T _S used for calculating the temperature adjustment command value are converted into internal values so as to be suitable for computer processing. Used above, the temperature adjustment command value itself is also processed as an internal value. For example, as shown in FIG. 19, the AD conversion value SD of the temperature sensor value is filtered by a primary digital filter, and the filtered value SDF is obtained.
To an internal value SDFI. This internal value is given in 2's complement, and one unit of the internal value corresponds to 0.25 ° C. Therefore, conversion to a physical quantity may be multiplied by 0.25.

[Control set temperature by learning set temperature characteristics

Here, in each area, the outside air temperature T _OUT and the room temperature T _R are divided into about 10 ° C., and are divided into 7 parts by adding 0 to 6, respectively. The boundary values of the outside air temperature T _OUT and the room temperature T _R are set appropriately higher when the temperature rises than when they fall, and so-called hysterisis is provided. This makes it possible to stabilize the control in the temperature range near this boundary value,
It is possible to avoid such a problem that the up switch and the down switch are alternately operated in the temperature range near the boundary value.

By the way, the up / down correction amount (hereinafter, referred to as a learning value) of the peripheral area adjacent to the relevant area may be set as follows. In other words, the up / down learning value of the peripheral area adjacent to the relevant area is opposite to the learning value of the peripheral area itself at this time, the up / down amount of the relevant area, and the relevant area centered around the peripheral area itself. That is, the learning value of the region on the side is obtained by weighted averaging.

The updating of the control set temperature T _S for the peripheral area adjacent to the corresponding area by such a weighted average is referred to as smoothing processing here. For this smoothing processing, for example, the number of setting changes of each area is changed. Let X (N, M) be the setting change operation in X (I, J), and in the peripheral area of X (I, J), The learning value after the change, the current learning value of its own area (the area surrounding the area where the setting was changed), and the current learning value of the area on the opposite side of this area around this area itself , 1: 2: 1 weighted averaging to update the learning value.

In this case, the peripheral area X of X (I, J)
The learning values of (I-1, J-1) to X (I + 1, J + 1) are
It can be calculated by the following formula. X (I-1, J) = [X (I-2, J) + X (I-1, J) * 2 + X (I, J)] / 4 X (I + 1, J) = [X (I + 2, J) + X (I + 1, J) * 2 + X (I, J)] / 4 X (J, J-1) = [X (I, J-2) + X (I , J-1) * 2 + X (I, J)] / 4 X (J, J + 1) = [X (I, J + 2) + X (I, J + 1) * 2 + X (I , J)] / 4 X (I-1, J-1) = [X (I-2, J-2) + X (I-1, J-1) * 2 + X (I, J)] / 4 X (I + 1, J-1) = [X (I + 2, J-2) + X (I + 1, J-1) * 2 + X (I, J)] / 4 X (I- 1, J + 1) = [X (I-2, J + 2) + X (I-1, J + 1) * 2 + X (I, J)] / 4 X (I + 1, J + 1 ) = [X (I + 2, J + 2) + X (I + 1, J + 1) * 2 + X (I, J)] / 4 The above equation is, for example, the area A in FIG.₃₃Set in a part like

X (I-1, J-1) = [X (I-1, J-1) * 3 + X (I, J)] / 4 X (I-1, J) = [X (I -1, J) * 3 + X (I, J)] / 4 X (I-1, J + 1) = [X (I-1, J + 1) * 3 + X (I, J)] / 4 Here, if the set temperature up switch 7 or the set temperature down switch 8 is operated by one unit, it is set that the set temperature for control T _S is raised or lowered in units of 0.25 ° C. If the one less than one unit operation is truncated, for example, at the beginning of learning (that is, when the correction values are all 0), the area A ₃₃ (the outside temperature T _OUT and the room temperature T _R is When the set temperature in the range of approximately 10 ° C. to approximately 20 ° C. is increased by 1 ° C., the learning value of each region as shown in (a) to (d) of FIG. Will be updated.

That is, the learning value X (3,3) is increased by 4 units so as to correspond to 1 ° C, and the learning values X (2,2), X (2,3), X ( 2, 4), X
(3,2), X (3,4), X (4,2), X (4
Each of 3) and X (4,4) goes up by 1 unit only when X (3,3) goes up by 4 units. In the middle of this, as shown in (a) to (c), these learning values are rounded down to 0.

Here, [see FIG. 6 (d)], a region A ₄₃ (outside air temperature T _OUT within a range of approximately 10 ° C. to approximately 20 ° C. and room temperature T _{R of} approximately 20 ° C. to approximately 30 ° C.). When the set temperature of the area within the range of ° C) is lowered by 1 ° C, the learning value of each area is updated as shown in (e) to (h) of FIG. That is, the learning value X (4,3) is lowered by 4 units so as to correspond to 1 ° C., and the learning values X (3,2), X (3,4) excluding the area A ₃₃ in the surrounding area ), X
(4,2), X (4,4), X (5,2), X (5
3) and X (5,4) are both 0 due to the truncation processing.
Becomes Note that the truncation process is performed as 0.0 with the decimal point set to 0 even when the number is negative such as −0.75. Further, the learning value X (3,3) of the area A ₃₃ is
When the learning value X (4,3) decreases by one unit, it is calculated by the following equation and further rounded down to become 2 [see FIG. 6 (e)].

X (3,3) = [X (2,3) + X (3
3) * 2 + X (4,3)] / 4 = [1 + 4 * 2 + 0] /
4 = 9/4 = 2.25 → 2 (truncation processing) By repeating such processing, X (3,3) is 1 [see FIG. 6 (f)], 0 [see FIG. 6 (g)]. , 0 [Fig. 6
(See (h)].

If the peripheral area is not updated in this way, as shown in FIGS. 7A to 7H, only the area that has been changed may have a large correction amount locally. Smooth control cannot be realized. When learning is performed in this way and the learning value of each area is updated, as a result, the learning value (temperature unit) of each area is set as shown in FIG. 10, for example. Then, the map of the control set temperature corrected by such a learning value is as shown in FIG. Further, when the map shown in FIG. 11 is displayed three-dimensionally, it becomes as shown in FIG.

As shown in FIG. 8, the learning-corrected set temperature for control is increased or decreased with respect to the reference set temperature (see FIG. 9) for each region of room temperature and outside air temperature. Therefore, for example, when the outside air temperature changes when the room temperature is 10 to 20 ° C., the control set temperature changes as shown in FIG. That is, if the learning correction is not performed, the set temperature for control does not change even if the outside air temperature changes as shown in FIG. 13, but if the learning correction is made, the setting change operation is performed as shown in FIG. Even if it does not perform, the set temperature for control changes according to the outside air temperature.

The set temperature storage means 22 stores a set temperature for control having an initial value of 25 as shown in FIG. 11, for example. However, instead of the set temperature for control itself,
You may make it memorize | store the learning value (correction value with respect to reference | standard setting temperature) as shown in FIG. [Use of Set Temperature for Control] In this way, the set temperature storage means 22 stores, for example, the set temperature for control shown in FIG. 11 for each area. The temperature is used to set the temperature adjustment command value F as shown in the above equation (1). That is, the temperature adjustment command value calculating means 23 periodically fetches the room temperature value T _R and the outside air temperature value T _OUT from the room temperature sensor 11 and the outside air temperature sensor 12, and as shown in FIG. The control set temperature T _S stored in the area corresponding to the room temperature value T _R and the outside air temperature value T _OUT is taken in, and the room temperature value T _R , the outside air temperature value T _OUT and the set temperature for control T taken in are taken. Based on _S , the temperature adjustment command value F is calculated by the equation (1).

When the temperature adjustment command value F is calculated in this way, as shown in the temperature adjustment allocation diagram (see FIG. 2), the compressor control amount storage means 25 as the temperature control amount storage means 24 and the inside / outside air are stored. Switching control amount storage means 26, outlet control amount storage means 27, and air mix damper control amount storage means 2
8, according to the set characteristics stored in the air volume control amount storage means 34, each control of the on / off of the compressor, the switching of the inside / outside air, the switching of the outlet, the opening of the air mix damper, and the blower air volume from the temperature adjustment command value F. Find the value. Based on these control values, on / off of the compressor, switching of the inside / outside air, switching of the air outlet, opening of the air mix damper, and blower air volume are controlled.

[Display of Set Temperature] The temperature indicator 15 includes
Although the set temperature is displayed, this set temperature is a display set temperature different from the control set temperature T _S. This display set temperature is always set to the reference set temperature (25 ° C) immediately after the key switch (ignition switch) is turned on or immediately after the air conditioner switch is turned on.
The display is started from C), and thereafter, while the key switch is kept in the ON state or the air conditioner switch is kept in the ON state, the set temperature change switches 7, 8 are set.
When is operated, the set temperature for display is also increased or decreased according to this operation.

That is, the control set temperature T _S is stored in the set temperature storage means 22 while being appropriately updated by learning, and the stored contents are saved even if the key switch (ignition switch) is turned off. . Therefore, the control set temperature T _S in the set temperature storage means 22 often becomes a value different from the reference set temperature (25 ° C.) when updated by learning (see FIG. 11), but the display setting is set. The temperature is always the standard set temperature (25 ° C) at the start of control.
The display starts from.

Then, for example, as shown in FIG. 15C, when the driver operates the set temperature change switches 7 and 8, the display set temperature is set to the reference set temperature (25 ° C.) as an initial value. Therefore, the control set temperature T _S is changed or updated from the initial value by using the update value obtained by the learning so far as the initial value by an amount according to the operation content of the set temperature change switches 7 and 8. Be done.

For example, as shown in FIG. 15 (A), when the key switch (ignition switch) is turned on / off, the set temperature for display becomes the reference set temperature (25) as shown in FIG. 15 (B). .Degree. C.) as an initial value, the temperature is changed by an amount corresponding to the operation contents of the set temperature change switches 7 and 8. In this way, the display set temperature different from the control set temperature is displayed without displaying the control set temperature as it is. If the control set temperature is displayed as it is, the operator may feel uncomfortable. Because there is. That is, as described above (see FIG. 12), the control set temperature may change due to changes in the outside air temperature or the room temperature without operating the set temperature change switches 7 and 8.
Although the set temperature change switches 7 and 8 are not operated in this way, the operator will feel uncomfortable if the display of the set temperature changes. Therefore, the set temperature for display different from the actual set temperature used for control is displayed so that it can be used as a guide for the operator to change the set temperature.

[Blower Air Volume Control] Regarding the blower air volume (blowing air volume), when the auto switch 14 is turned on, the air mode is switched to the automatic mode, and the blower air volume is controlled to the optimum air volume through the air conditioner ECU 13. The blower air volume is controlled to be increased or decreased according to the input operation of 9 and 10.

That is, the control value of the blower air volume is obtained from the temperature adjustment command value F in accordance with the set characteristic stored in the air volume control amount storage means 34. As shown in FIG. 1, it is obtained in this way. An adder 35 is provided for performing an increase / decrease calculation according to the input operation of the blower air flow rate change switches 9 and 10 for the control value of the blower air flow rate. It is designed to be controlled.

As the correction amount sent to the adder 35, the learning value stored in the set air volume storage means 32 is used. In the set air volume storage means 32, as in the set temperature storage means 22, for example, as shown in FIG.
The air volume increase / decrease learning value is stored in each of a plurality of areas A _{00 to} A ₆₆ divided in a matrix by the outside air temperature T _OUT and the room temperature T _R , similarly to the control set temperature T _S. The learning value of the air volume increase / decrease learning value is updated by the learning operation unit 31 as the set air volume characteristic learning means by the same learning as in the case of the control set temperature T _S.

That is, in the set air volume characteristic learning means 31, when the setting change operation of the set air volume change switches 9 and 10 is performed, the contents of the setting change operation at this time (that is, whether the set air volume is increased or decreased) is described. , Outside temperature T at this time
Based on the state of _OUT and the room temperature T _R , the control set temperature T _S of the corresponding region of the set air volume storage means 32 and the region around this region is updated. The specific content of this update is
Similar to the case of learning the set temperature, as shown in FIG. 16, the learned value of the corresponding area of the air volume increase / decrease map stored in the set air volume storage means 32 is taken out and increased / decreased to the corresponding area again. Write and update.

As a result of such learning, the learning value (air volume increase / decrease amount) of each area of the set air volume storage means 32 is updated, and an air volume increase / decrease map is formed which is in an increase / decrease state according to each area. . This air volume increase / decrease map is shown in FIG.
Similar to that shown in 0, each initial value is a map of 0. As shown in FIGS. 1 and 17, such a learning value corresponds to the blower air volume obtained from the temperature adjustment command value F in accordance with the setting characteristics stored in the air volume control amount storage means 34. The learning values of the air volume increase / decrease stored in the corresponding areas of 32 are added by the adder 35 to obtain the final blower air volume control amount, and the blower air volume is controlled based on this. Although various corrections are made in FIG. 17 in addition to the correction based on the information in the set air volume storage means 32, such various corrections may be omitted.

Since the extreme change of the set air volume may affect the automatic mode control, the learning value (air volume increase / decrease amount) may be clipped at an appropriate upper limit value or lower limit value. In addition, the blower air volume displayed by the air volume indicator 16 is
The actual blower air volume is displayed. This is because in blower auto mode, the blower air volume generally changes automatically, and displaying the actual blower air volume does not cause any discomfort, but rather the actual blower air volume is displayed to the operator. This is because it is considered convincing.

[Identification of Setting Change Operator] In this learning control type automobile air conditioner, each learning of the above-mentioned set temperature and set air volume is performed while identifying the operator. That is, a plurality of learning value files are prepared in advance in the set temperature storage means 22 and the set air volume storage means 32, and a dedicated learning value file is used for each operator (usually a driver). ing.

In FIG. 1, the set temperature storage means 22 and the set air volume storage means 32 are provided with first and second two kinds of learning value files, for example, the first learning value files FT1, FW1. Is used for the operator (driver) A, and the second learning value files FT2, FW2 are used for the operator (driver) B. Therefore, it is necessary to identify the operator (driver).

Here, the keyless entry system 4
0 is used to identify the driver. The keyless entry system 40 shown in FIG. 1 is of a radio wave type, and a driver can transmit a radio wave to a receiver 43 mounted on a vehicle body by a transmitter 41 or 42 to remotely control locking and unlocking of a door. ing. When a radio wave is transmitted from the transmitter 41 or 42 to the receiver 43, this radio wave signal is input to a microcomputer 44 connected to the receiver 43, and from this microcomputer 44, driver determination means provided in the air conditioner ECU 13 (Operator identification means) 36 is input.

In this way, it is possible to identify which of the first transmitter 41 and the second transmitter 42 has transmitted, based on the signal input to the driver determination means 36. Generally, the transmitters 41 and 42 are provided for each driver, so that the driver A uses the first transmitter 41 and the second transmitter 41, for example.
It is possible to correspond to the fact that it is the driver B who uses the, and the operator can be identified (driver's identification).

Note that the operator identification signal is transmitted several times (three times in FIG. 18) only immediately after the ignition key is turned on, as shown in FIG. 18, for example, as shown in FIG. May be input to. Then, the driver determination means 36 identifies the operator if the identification signal is detected even once. By thus transmitting the operator identification signal several times, it is possible to reliably pick up the signal, and to reliably identify the operator.
Note that the identification signal may be continuously transmitted after the ignition key is turned on. In this case, the driver determination unit 36 identifies the operator even if the identification signal is detected even once after the ignition key is turned on, and then ignores the identification signal.

By the way, the operator identification signal includes the driver A
In addition to the identification signal A corresponding to (1) and the identification signal B corresponding to the driver B, a signal (no identification signal) C indicating that the driver cannot be identified is prepared. Therefore, in the driver determination means 36, whether the driver is the driver A or the driver B
It can be determined in three ways: whether or not it can be determined.

In the microcomputer ECU 13D, the driver is
If it can be determined which of B is selected, the learning value file corresponding to the set temperature storage means 22 and the set air volume storage means 32 is selected and updated or used for control. If neither B can be determined, the control based on the learning of the set temperature or the like is not performed, and the setting change operation is performed based on the reference set temperature (25 ° C) as in the conventional case. It is designed to control.

[Overall Control Operation] Since the learning control type automobile air conditioner as one embodiment of the present invention is configured as described above, for example, the operation shown in FIG. The air conditioner control is performed by repeating the procedure. That is, first, initial setting is performed (step S10), but here, the display set temperature is set to 25 ° C. which is the reference value (reference set temperature). Next, the detected values of the room temperature T _R and the outside temperature T _OUT are input (step S2).
0), it is determined whether or not the set temperature has been changed (step S30).

When the set temperature is changed, the learned value of the set temperature information stored in the set temperature storage means 22 corresponding to the areas of the present room temperature and the outside air temperature is updated (step S4).
0). That is, when there is a setting change operation of the set temperature change switches 7 and 8, the set temperature characteristic learning means 21 describes the contents of the setting change operation at this time (that is, whether the set temperature is raised or lowered), and Outside temperature T _OUT and room temperature T
Based on the state of _R , the control set temperature T _S of the corresponding area of the set temperature storage means 22 and the surrounding area is updated.

Further, the display set temperature is updated (step S50). That is, the reference set temperature (25 ° C.) is used as the initial value for the set temperature for display, and the set temperature is changed from this initial value by an amount corresponding to the operation content of the set temperature change switches 7 and 8. Of course, if the set temperature is not changed, these steps S40 and S50 are not performed.

Then, it is determined whether or not the set air volume is changed.
Set (step S60) and the set air volume is changed,
Current room temperature and outside temperature stored in the set air volume storage means 32

If the set air volume is not changed, the process of step S70 is not performed. Then, the temperature control amount is obtained from the outside air temperature, the room temperature, and the set temperature information for control through the temperature control amount storage means, and the temperature control is performed based on the temperature adjustment control amount (step S80). Then, the air volume adjustment control amount is obtained from the control set temperature information and the control set air volume information, and the air volume control is performed based on this (step S90).

Further, the set temperature for display is displayed on the set temperature display 16 (step S100), and the current air volume is displayed on the blower air volume display 15 (step S110). In this way, in the learning control type automobile air conditioner, when the setting change operation of the set temperature change switches 7 and 8 and the set air volume change switches 9 and 10 is performed, the set temperature characteristic learning means 21 and the set air volume characteristic learning are performed. On the basis of the contents of the setting change operation at this time and the states of the outside air temperature T _OUT and the room temperature T _R at this time, the means 31 and the corresponding region of the set temperature storage means 22 and the set air volume storage means 32 and the surrounding area While updating the set temperature for control T _{S of the area} and the amount of change in the air volume, this is saved for each area of the outside air temperature and the room temperature.

Therefore, for example, even if the ignition key is turned off or the air conditioner switch is turned off, when the air conditioner control is started next time, the air conditioning is performed based on the learning values stored in the set temperature storage means 22 and the set air volume storage means 32. Control will be performed. In particular, since the learning values are stored in the set temperature storage means 22 and the set air volume storage means 32 for each region of the outside air temperature and the room temperature, for example, it is possible to perform the air conditioner control according to the characteristics desired by the driver for each season. become.

That is, as shown in FIG. 21, in the summer,
As the air conditioner is operated from a state where the outside temperature is high and the room temperature is high, the actual room temperature decreases to approach the set temperature. In winter, when the air conditioner is operated from a state where the outside temperature is low and the room temperature is low, the actual room temperature rises to approach the set temperature. In this way, since the room temperature changes in the process of operating the air conditioner, the region defined by the outside temperature and the room temperature also changes, but since learning is performed in each changing region, learning once When the control is performed, the air conditioning control can be performed so as to finely correspond to the driver's preference in the process of adjusting the room temperature.

Of course, if such learning is performed once for each season, the air conditioning control for the full season can be realized without any operation. In addition, while recognizing the driver (operator),
Since learning control can be performed, there is an advantage that even in an automobile used by a plurality of drivers, each driver can realize desired air conditioning control. Of course, when the driver (operator) cannot be recognized, the control is started based on the standard air conditioning control, so that there is an advantage that extreme air conditioning control can be avoided.

And setting characteristic learning means for correcting and updating the control set temperature information stored in the set temperature storage means according to the learned characteristics while learning the characteristics of temperature setting with respect to the outside air temperature and the vehicle interior temperature. With such a configuration, once the operator performs a change operation to obtain a desired air conditioning condition under the environment of a certain outside air temperature and vehicle interior temperature, thereafter, the outside operation like that at the time of this change is performed. In an environment of temperature and vehicle interior temperature, even without a change operation, there is an advantage that so the temperature adjustment is performed on the state of the preference.
Further, since it can be realized only by adding the learning control function to the conventional technique, there is an advantage that the structure of the device is simple and can be constructed at low cost.
