FIG. 2 shows a specific configuration of one embodiment of the vehicle air conditioner of the present invention. At the most upstream side of the air conditioning unit 20, an inside / outside air switching damper 22a is installed. The inside / outside air switching damper 22a is arranged at a portion where the outside air introduction port and the inside air introduction port are separated, and selects a ratio of inside air to outside air to be introduced into the air conditioning unit 20 by an actuator (not shown).

The blower motor 24 and the fan 23 fixed to the blower draw air into the air conditioning unit 20 and blow air to the downstream side of the unit 20, and an evaporator 25 and a heater core 26 are provided downstream of the fan 23. ing.

The evaporator 25 is combined with a compressor (not shown) or the like to constitute a cooling cycle, and cools the passing air. In the heater core 26, engine cooling water (not shown) circulates and heats air passing therethrough.

An air mix damper 22b is provided upstream of the heater core 26.
The opening of 2b is adjusted by an actuator (not shown), whereby the ratio of the air passing through the heater core 26 and the ratio of the air bypassing the heater core 26 is adjusted, and the temperature of the air blown into the most downstream passenger compartment is controlled.

The DEF blower damper 22c, the FACE blower damper 22d, and the FO
An OT blowing damper 22e is provided. The air whose temperature is controlled is blown out in each blowing mode by operating each of these dampers by an actuator (not shown).

The amount of air blown is controlled by a drive circuit 30 that drives the blower motor 24 based on an output signal from a microcomputer 31. The microcomputer 31 includes a central processing unit (CPU), ROM, RA (not shown).
It has an M, a standby RAM, an I / O port, an A / D conversion function, etc., and is itself well known.

The standby RAM is an RA for storing (backing up) a value obtained by learning a passenger's preference even when an ignition switch (hereinafter referred to as IG.) Is off.
M and IG. Is off even if battery is off
G. FIG. The power is supplied directly without going through. Also, the microcomputer 31 is configured with a backup power supply (not shown) that supplies power to the microcomputer 31 for a short time even when the power is removed from the battery.

The microcomputer 31 has an operation unit 37
Is input. The operation unit 37 includes an AUTO switch for setting an automatic control state (not shown), a manual inside / outside air changeover switch, and a manual air outlet mode changeover switch (D
EF, FACE, FOOT, B / L, F / D), a manual air flow rate changeover switch, and the like. In one embodiment, the manual control means includes the operation unit 37 and step 410 (FIG. 6) described later.

The microcomputer 31 has an internal temperature sensor 33, an environmental condition affecting the air conditioning in the vehicle.
The signals are input from the outside air temperature sensor 34 and the solar radiation sensor 35 via the respective level conversion circuits 32. These are A / D-converted by the microcomputer 31 and environmental conditions are read. The occupant's favorite temperature is input from the temperature setting switch 36, level-converted by the level conversion circuit 32, and input to the microcomputer 31. In one embodiment, the environmental condition detecting means is replaced by the internal temperature sensor 3.
3, an outside air temperature sensor 34 and a solar radiation sensor 35.

In one embodiment, each damper 22
a to 22e, fan 23, and blower motor 24
Constitutes air conditioning means. Next, the learning switch will be described with reference to FIG.

In one embodiment, the learning switch 10
The air conditioner panel in the vehicle compartment is disposed at a position where it is easy for the driver to operate and visually recognize, and includes a momentary switch 10a and a learning state display LED 10b. As described later, the learning switch 10 is configured so that a mode after learning is prohibited (a learning prohibition mode 1, a learning prohibition mode 2, and a factory shipment mode) is selectively used depending on a time actually pressed by an occupant.

Next, basic control by the microcomputer 31 will be described with reference to FIG. The microcomputer 31 has an IG. Control is started in step 100 when the power is turned on, and the flow advances to step 110 to set initial values such as various conversions and flags.

In the next step 150, the internal temperature sensor 3
3. Inputting environmental conditions based on sensor signals from the outside air temperature sensor 34 and the solar radiation sensor 35,
6 and the operation unit 37, the state of the operation switch is input. Further, a signal from the learning switch 10 described above is also input.

In the next step 200, the target blowing temperature (TAO) of the air blown into the vehicle compartment is calculated according to the following equation 1 based on the environmental conditions and the like input in step 150.

[0024]

[Equation 1] TAO = K _SET × T _SET −K _R × T _R −K _AM ×
_{T AM -K S × T S +} C However _{K SET, K R, K AM} , K S is a coefficient, C is a constant, T _R is the inside air temperature, T _AM is the outside air temperature, T _S is the amount of solar radiation. T _SET is a set temperature calculated based on a signal from the warm feeling setting switch 36 and the environmental condition.

Next, the routine proceeds to step 300, where the opening of the air mix damper 22b is calculated with respect to TAO, and an actuator (not shown) is driven by the driving circuit 30 so that the opening becomes equal to this opening.
Control the temperature of the air sent from the outlet. However, there is an individual difference in the passenger compartment temperature that passengers prefer, and it is difficult to determine uniformly. Therefore, in one embodiment, when the occupant manually operates the warm feeling setting switch 36, the occupant's favorite vehicle interior temperature is learned, and the temperature characteristics reflect the occupant's preference.

Next, the routine proceeds to step 400, where the amount of air is calculated, and the fan 23 fixed to the blower motor 24 is rotated via the drive circuit 30 to control the amount of air. But,
The airflow desired by the crew varies from individual to individual, and it is difficult to determine uniformly. Therefore, in one embodiment, the air volume desired by the occupant is learned at the time of manual operation of the occupant, so that the air blowing characteristics reflect the occupant's preference. This will be described later in detail.

Then, the program proceeds to a step 500, wherein the inside / outside air introduction ratio by the inside / outside air switching damper 22a is calculated, and an actuator (not shown) is controlled via the drive circuit 30. Further, in one embodiment, the inside / outside air mode of the occupant's preference is learned at the time of the manual operation of the occupant, so that the inside / outside air characteristic reflecting the occupant's preference is obtained.

Next, at step 600, the mode state is calculated, and actuators (not shown) for driving the DEF blower damper 22c, the FACE blower damper 22d, and the FOOT blower damper 22e are controlled via the drive circuit 30. Further, in one embodiment, the occupant's favorite blowing mode is learned at the time of manual operation of the occupant, and the blowing characteristic reflects the occupant's preference.

Then, the program proceeds to a step 700, wherein a compressor (not shown) is controlled. After the processing of step 700,
Returning to step 150, various signals are read again, thereby calculating TAO in step 200.
Steps 300, 400, 500, 600, 7 according to O and the state of the switch read in step 150
The control of air conditioning is repeated by 00.

Next, the learning control of the blowing characteristics (step 400 in FIG. 4) will be described in detail with reference to FIGS. In step 401 following step 400, it is determined whether or not the air volume is manually set (changed) by the operation unit 37. If there is no manual setting, it is determined as NO and the routine proceeds to step 402. Since the initial value of F1 is set to 0 in step 110 (FIG. 4), NO is determined in step 402, and the process proceeds to the next step 406 (FIG. 6).

When the blowing amount is in the automatic control, F2 = 0,
In step 406 it is determined NO, and the process proceeds to step 407, the blower voltage V _F is determined according to the characteristics of the blower voltage with respect to the target blowing temperature TAO (Figure 7). The blower voltage characteristic is indicative of the blower voltage V _F for the most common human TAO, this property is stored in the ROM.

This characteristic is common in the automatic control of the air flow, and TAO decreases along the left side of the horizontal axis. TAO
If ≤ T1, the state becomes MAX COOL and the blower voltage becomes V
_H. This state means a rapid cooling state in which the inside air temperature is considerably higher than the set temperature.

The TAO is gradually rise from T1, until the T3 to the inside air temperature is approaching the set temperature, blower voltage V _F is gradually reduced. Inside air temperature is in a state close to the set temperature T3 ≦ TAO <T5 in blower voltage V _F becomes V _L is L _O. TAO gradually becomes higher when the blower voltage V _F from the T5 gradually increases.

When TAO ≧ T7, V _F = V _H. In this state, the inside air temperature is much lower than the set temperature,
It means that it is in HOT state. The blower voltage characteristic of this TAO is as follows.
Seven points (T1, V1), which are divided and plotted, for example, as a blower voltage V1 with respect to T1, (T2,
V2), (T3, V3), (T4, V4), (T5, V
5), (T6, V6), and (T7, V7) are configured as lines connecting these, and these seven points are stored in the ROM in advance.

In step 407 in FIG. 6, when the battery is connected and the microcomputer 31 is supplied with + B power and the air volume is not manually set,
According The most common (personal preference is not learned) a blower voltage characteristic shown in FIG. 7, the blower voltage V _F is calculated based on TAO obtained in step 200 (FIG. 4).

[0036] At step 411, the blower voltage V _F which is computed in step 407 through the driving circuit 30 is applied to the blower motor 24. Thereafter, the process proceeds to step 412, exits the subroutine of step 400, and proceeds to step 500 of FIG.

On the other hand, if the air volume is manually set (changed) by the operation unit 37, the determination is Yes in step 401, and the process proceeds to step 408. In step 408, a learning request flag F1 and a flag F indicating the manual setting of the air volume are set.
2 is set, and the counter CNT1 for indicating the time after the manual setting is cleared. CNT1 is always incremented by a timer interrupt (not shown) at every predetermined time, for example, every 0.1 second.

In the next step 409, the current TAO
Is stored as CTAO, and then the process proceeds to step 406. In step 406, F2 = 1 in step 408
Is set to "Yes", so that it is determined that the
Proceeds to 10, changing the blower voltage V _F to manually set the blower voltage V _M. Then the process proceeds to step 411, the blower motor 24 as a blower voltage V _M which is manually set
, And exits the subroutine and proceeds to step 500 in FIG.

Next, if the occupant is manually setting the air volume when the subroutine 400 is called, steps 401, 408, 409, 406, 410, and 41 are performed as described above.
The control is performed in the order of 1 and 412 to exit the subroutine, and the applied voltage of the blower motor 24 is controlled so that the blower voltage becomes a manually set blower voltage.

However, when the manual setting is completed, step 4
At 01, No is determined, and the routine proceeds to step 402. Since the learning request flag F1 is set to 1 in step 408, the determination in step 402 is Yes, and the process proceeds to step 403.

Since CNT1 is cleared to 0 in step 408 and is always incremented every 0.1 seconds as described above, CNT1 <C1 (C
1 is a constant, and here, C1 = 30).
Proceed to. In step 406, since the manual setting flag F2 is set to 1 in step 408, the determination is Yes. Thereafter, control is performed in the order of steps 410, 411, and 412 to exit the subroutine, and the blower voltage is set to the manually set blower voltage. , The voltage applied to the blower motor 24 is controlled. Steps 400, 401, 402, 403, 406, and 4 described above are performed within 3 seconds (C1 = 30) after the manual setting is completed.
Controls 10, 411, and 412 are repeatedly executed.

Thereafter, when three seconds or more have passed after the completion of the manual setting, CNT1 ≧ C1 is satisfied, and the determination in Step 403 is Yes, and the process proceeds to Step 420. At this time, if the learning mode is set, the process proceeds to step 421. In other words, if it is neither the learning inhibition mode 1 as the first learning change inhibition mode described later, the learning inhibition mode 2 as the second learning change inhibition mode, nor the factory shipment mode, step 4
Proceed to 21. If it is 3 seconds or more and 5 seconds or less after the completion of the manual setting, NO is determined in step 421 and step 42
Proceed to 3. Note that C2 = 50 in one embodiment.

In step 423, the learning state display LED 10b is provided to inform the occupant whether the learning of the blower voltage characteristic (FIG. 7) may be changed according to the manual setting.
A buzzer sounds at the same time as blinking (FIG. 3). In addition to this method, a voice synthesizing device may be separately provided, and the occupant may be notified by voice such as “learn”.

By the above notification, the occupant can know that the blower voltage characteristics (FIG. 7) are learned and changed according to the manual setting. Here, if the learning change is to be prohibited for some reason, the learning change is prohibited by the occupant pressing the learning switch 10 within 2 (= 5-3) seconds after the notification in step 423 is made. Can be. That is, if the learning switch 10 is pressed within two seconds from the start of the notification in step 423, the determination in step 420 of FIG. 5 is NO, and the process proceeds to step 422. That is, step 405 as learning change means can be bypassed. However, if the learning switch 10 is pressed after 2 seconds from the start of the notification in step 423, the process proceeds to step 420 and step 421, and YES is determined in step 421, and the blower voltage characteristic is determined in step 405. Learning changes. In one embodiment, the learning change prohibiting means is constituted by step 422 and step 425 described later.

By the way, there are several possible reasons for the above, but in one embodiment, two of them are given and a learning prohibition mode is provided for each reason. These two modes can be easily used depending on the time during which the occupant is actually pressing the learning switch 10.

For example, the first reason for prohibiting the learning change is that the physiological condition of the occupant is different from usual, or that the vehicle is driven behind a truck. When it is desired to prohibit the learning change for the first reason, the occupant can prohibit the learning change by pressing the learning switch 10 for a period of three seconds or less. The mode at this time is called learning inhibition mode 1.
In the embodiment, when the learning inhibition mode 1 is set, the learning state display LED 10b is turned off, a buzzer sounds, and the occupant is notified by a voice such as "set learning inhibition mode 1". If it is desired to return to the learning mode again after the learning prohibition mode 1 has been entered, the learning switch 10 must be pressed again for a period of less than three seconds, or an ignition switch (IG.)
Can be returned to the learning mode by turning it off once and then turning it on again.

A second reason for prohibiting the learning change is a case where the vehicle is lent to another person for several days. When the learning change is to be prohibited for the second reason, the learning change can be prohibited by the occupant pressing the learning switch 10 for 3 to 10 seconds. The mode at this time is referred to as learning inhibition mode 2. In one embodiment, when the learning inhibition mode 2 is set, the learning state display LED 10
b turns off, the buzzer sounds, and the occupant is informed by voice such as "Let's go into learning inhibition mode 2." When returning from the learning inhibition mode 2 to the learning mode, the learning switch 10 may be pressed again for 3 to 10 seconds. In this case, the IG. Is turned off once and then turned on again, so that it does not return to the learning mode. Therefore, once the learning prohibition mode 2 is set, the learning prohibition state is maintained even if the vehicle is lent for several days. be able to.

In one embodiment, a factory shipment mode is provided in addition to the first and second learning inhibition modes.
For example, when the blower voltage characteristic after learning change becomes worse than the initial characteristic (FIG. 7), or when the owner of the vehicle changes, such as when the vehicle is bought second-hand, the factory By setting to the shipping mode, the blower voltage characteristics can be returned to the initial characteristics. In one embodiment,
By pressing the learning switch 10 for 10 seconds or more, the factory shipping mode can be set. In one embodiment, when the factory shipping mode is set, the learning state display LED 10b is turned off, a buzzer sounds, and the occupant is notified by a voice such as "Switch to factory shipping mode". When returning from the factory shipping mode to the learning mode, the learning switch 10 is set to 1 again.
Press it for more than 0 seconds.

FIG. 8 shows the relationship between the learning prohibition mode 1, the learning prohibition mode 2, the factory shipping mode, and the learning mode with respect to the pressing time (t) of the learning switch 10. Here, A in FIG. 8 indicates that the pressing time (t) of the learning switch 10 is t> 3 seconds, and B is 3 seconds ≦ t <1.
0 seconds, and C indicates that T ≧ 10 seconds.

At step 422 (FIG. 5), it is determined from the pressing time (t) of the learning switch 10 whether the learning inhibition mode 1 or the learning inhibition mode 2 is set. Step 42
If it is determined in step S2 that the mode is the learning prohibition mode 1 or the learning prohibition mode 2 (YES), step 404 is performed.
If the determination in step 422 is NO, the process proceeds to step 425 to set the factory shipping mode, and clears the blower voltage characteristics that have been learned and changed. Thereafter, the process proceeds to step 404.

After resetting the learning request flag F1 in step 404, control is performed in the order of step 406, step 410, step 411, and step 412 to exit the subroutine and proceed to step 500 in FIG.

As described above, when the occupant manually sets the air flow to his or her desired amount, the blower voltage characteristics in the auto mode reflect the occupant's preference after a lapse of a predetermined time (here, 5 seconds) after the manual setting is completed. Change to characteristics.

Thereafter, when the occupant operates the AUTO switch of the operation unit 37, the manual setting flag F2 is reset in step 150 (FIG. 4), and the blower voltage is automatically controlled with the blowing amount. That No is determined in step 406, calculates the blower voltage V _F by the blower voltage characteristic after learning changed in step 407, the blower voltage that V
_The voltage applied to the blower motor 24 is controlled so as to be _F.

[0054] Therefore, the preference learning at step 405 each time the occupant changes the air volume to suit their own preferences, calculates the blower voltage V _F is the blower voltage characteristic after incorporating learned preferences during automatic operation is, the blower voltage controlling the voltage applied blower motor 24 as a its V _F.

Here, the reason why the learning is performed in step 405 only when a predetermined time has elapsed after the completion of the manual setting of the air flow rate is that learning is performed when the occupant is manually setting, or when learning is manually performed by mistake. This is to avoid learning and learning when the occupant prefers a short-term change in the air flow.

In the above-described embodiment, the automatic control means is controlled by steps 300, 400 and 50.
0, step 600. As described above, in the above-described embodiment, the occupant is configured to notify the occupant of the learning change of the blower voltage characteristic in advance, and the learning switch 10 for inhibiting the learning change is provided. If you do not want to change learning, you can easily prohibit it.

Although the embodiment in which the learning change of the air flow rate is prohibited has been described above, the present invention is not limited to this, and can be applied to control of inside / outside air characteristics, blow temperature characteristics, blow mode characteristics, and the like. It is.

In the above embodiment, the learning switch 10
Is constituted by a momentary switch as shown in FIG. 3, but may be constituted by a rotary switch as shown in FIG.

In the above embodiment, the learning inhibition mode 1
As a method of returning from the learning mode to the learning mode, a method of pressing the learning switch 10 again within 3 seconds and a method of once turning off the ignition switch (IG.) And then turning it on again are adopted. After a predetermined time (for example, 10 minutes) elapses, the mode may automatically return to the learning mode. Further, in the above-described embodiment, the learned content is designated as IG. Standby R for memorizing even when off
Although the AM is used, a nonvolatile memory may be used without using the standby RAM. Also in this case, IG. When the power is turned off, the learned contents are saved even if the power supply from the battery is stopped.
