2. Description of the Related Art Conventional vehicle air-conditioning control systems include
There is one disclosed in Japanese Patent Laid-Open No. 2-147428. This technology is based on the set room temperature set by the passenger's operation, the detected room temperature detected by the room temperature sensor installed in the passenger compartment, the amount of solar radiation detected by the insolation sensor installed in the vehicle body, the outside air temperature sensor, etc. The so-called automatic air conditioner (automatic air conditioner) that controls the room temperature in the vehicle interior to the target set room temperature by adjusting the temperature and air volume of the conditioned air, the outlet position, etc., according to the thermal environment information inside and outside the vehicle such as the outside air temperature・ Air conditioner).

In such an air conditioner, first, the values of predetermined constants A to H used for the calculation of each step are read from the non-volatile memory built in the control device main body, and then the heat The sensor signal from each sensor as the environmental information detecting means, the room temperature set by the occupant, and the state of each switch are read, and the opening X of the air mix door that controls the passing amount of the cool air after passing through the evaporator is obtained. Where the air mix door opening X
Is calculated as follows. That is, the target outlet temperature T required to reach the set room temperature under the current heat load condition
of of Tof = A × Tptc + B × Tamb + C × Qsun +
D × Tic + E is calculated, and the air mix opening for achieving the outlet temperature Tof is calculated by X = F × Tof ² + G × Tof + H.

Then, when the target outlet temperature is Tof, the optimum outlet mode and the state of the inlet are determined.
Further, the blower fan voltage Vfan is determined based on the blower fan applied voltage characteristic that is predetermined so as to blow out the air volume according to the target blowout temperature Tof. After that, after outputting a control signal to each actuator so that the control amount calculated in each of the above steps is achieved, the processing of each of the above steps is repeatedly executed until the off switch is pressed.

However, in the above-described conventional vehicle air-conditioning control device, usually only one room temperature sensor is arranged due to cost constraints, etc., and in addition, the mounting of the room temperature sensor in the vehicle. Due to layout restrictions with other parts, the position is such that the instrument panel and ceiling are not affected by solar radiation, and the position differs for each vehicle. Therefore, the room temperature detected by the room temperature sensor does not always match the ambient temperature of the occupant, and the air flow distribution in the passenger compartment changes due to the selection of the outlet and the change of the outlet direction. The temperature at the mounting position also fluctuates. That is, even if the average temperature around the occupant is the same, there is a difference in the detected room temperature between the vent mode and the foot mode in the outlet mode, and the detected room temperature (Tic) including such fluctuation factors is used to obtain the target outlet temperature. (T
Since the value of of) is calculated, there is a possibility that the temperature will stabilize at a room temperature different from the desired set room temperature.

Therefore, a method of correcting the detected room temperature from a predetermined detection error characteristic is conceivable. At this time, although the detection error caused by the layout can be verified experimentally, it is possible to select the outlet and the outlet direction. The occupants have a wide variety of tastes, and it is virtually impossible to verify all combinations, and even if it is possible, storing the correction amounts for all combination conditions is a matter of memory capacity. In addition to increasing the number, it is necessary to arrange a detection sensor for detecting the louver position of the outlet in order to detect the direction of the outlet, which results in an increase in cost due to an increase in the number of parts. It was

The present invention has been made in view of the above,
The purpose is to accurately correct the detection error of the room temperature sensor that detects the temperature in the passenger compartment by self-correcting, and to automatically obtain the control characteristics that match the occupant's sensory characteristics.

Set to an and m respectively, and the outlet mode switch,
The selection state of the suction port switch is input (S301).

Air Mix Opening Process FIG. 7 shows details of the air mix opening process shown in FIG. First, the detected room temperature correction amount Tic, cor [i]
Is read (S401). Next, a smoothing process is performed on the stored detected room temperature map (S402). this is,
This process is performed in order to make the correction amounts of the adjacent storage areas as continuous values as possible. Specifically, for example, it is obtained by the following formula.

Assuming that the i-th storage amount is Tic, cor [i] (i = 1, 2, ..., N), (1-Ws) × Tic, cor [i] + Ws × Tic,
cor [i + 1], (i = 1), or Tic, cor [i] = (1-2 × Ws) × Tic, c
or [i] + Ws × Tic, cor [i−1] + Ws ×
Tic, cor [i + 1] (2 <i <n-1), or (1-Ws) * Tic, cor [i] + Ws * Tic,
cor [i-1] (i = n) where Ws is a weighting coefficient that satisfies 0 <Ws <1/3.

Next, Tic and cor [i] are corrected as shown below (S403). That is, Tic, cor = Tic + Tic, cor [i].

After that, the calculation of the target outlet temperature is executed as follows (S404). That is, Tof, cor = A × Tptc + B × Tamb + C × Q
sun + D × Tic, cor + E.

After the calculation of the target outlet temperature is performed, it is determined whether the average of the time derivative of the detected room temperature Tic is less than or equal to the specified value dT01, that is, whether the room temperature is stable (S4).
05). That is, if it is determined that d (Tic) / dt <dT01 and the room temperature is sufficiently stable at dT01 or less, the blowout temperature Tof, cor, step S10.
The predicted room temperature Tic, prd when blowing out with the air volume Vfan determined in 6 is obtained by solving the following differential equation by the difference method (S406).

[0037]

[Equation 1]

Next, the detected room temperature Tic and the predicted room temperature Tic,
It is determined whether or not the difference in prd is less than or equal to the predetermined value T02 (S4
07). That is, Tic-Tic, prd <T02 is determined. As a result, when it is determined that the temperature is T02 or more, the room temperature correction map is updated. That is, using the detected room temperature Tic, the predicted room temperature Tic, prd, the detected room temperature correction amount Tic, cor up to the previous time, and the outside air temperature Tamb and the input amount Qsun, a new room temperature correction amount Tic, co
r ′ [i] is calculated by the following equation (S408), that is, Tic, cor ′ [i] = Wcor × (Tic−Ti)
c, prd-Wex x (B x Tamb + C x Qsu
n)) + (1-Wcor) * Tic, cor [i].

Here, Wcor is a weight for correcting the correction amount, and 0 <Wcor <1. Wex is a coefficient for making the thermal disturbance outside the vehicle compartment due to the outside air temperature and the amount of solar radiation equivalent to the room temperature change,
It is obtained by analysis experimentally or thermodynamically. As shown in FIG. 12, the stored detected room temperature correction map stores Tic and cor for each outside air temperature.

After that, the air mix opening degree X is calculated by the following equation using the corrected target outlet temperature Tof, cor calculated in step S404. That is, the air mix opening X is obtained by X = F × Tof, cor ² + G × Tof, cor + H.

As described above, the detection error of the room temperature sensor for detecting the air temperature in the passenger compartment is set to the predicted room temperature predicted from the current blowing condition of the air-conditioning air and the steady-state deviation obtained by removing the thermal disturbance from the deviation of the detected room temperature. When the value is equal to or more than the value, the steady-state deviation is stored in the storage area corresponding to the thermal environment such as the outside temperature and the amount of solar radiation at that time, and when the same thermal environment area is reached next time, the stored steady-state deviation is stored. The target air conditioning condition is corrected by an amount corresponding to. As a result, the detection deviation of the detected room temperature caused by the layout or the preference of the occupant's blowing characteristic is self-corrected and accurately corrected, and the room temperature does not become different from the room temperature desired by the occupant.

Blow-Out Mode Processing FIG. 8 shows details of the blow-out mode processing shown in FIG. First, an outlet is selected using a predetermined outlet mode map according to the target outlet temperature Tof (S
501). Here, the balloon states in each mode are shown below. Vent mode: blows out only from the ventilator grill located on the instrument panel. Bi-level mode: blow out from both the ventilator grille and the foot outlet. Foot mode: Open at the foot outlet and the upper surface of the instrument, and blow out to the inside of the front window from the defroster outlet.

Next, it is judged whether or not the outlet mode switch 41 is pressed (S502), and if it is judged that it is pressed, the vent mode (S503), the bi-level mode (S504), the foot In the mode (S505) and the defroster mode (S506), an outlet mode corresponding to each is selected.

Suction Port Processing FIG. 9 shows details of the suction port processing shown in FIG.
First, the state of the suction port is selected using a predetermined suction port map according to the target outlet temperature Tof (S60).
1). Here, each state is REC: 100% 20% FRE: 20% outside air introduction, 80% inside air circulation FRE: 100% outside air introduction.

Next, it is judged whether or not the suction port switch is pressed (S602), and if it is judged that it is pressed, it corresponds to the outside air introduction (S603) and the inside air circulation (S604). Select the suction port to use.

Air Volume Processing FIG. 10 shows details of the air volume processing shown in FIG.
First, the blower fan applied voltage Vfan is selected using a predetermined blower fan applied voltage map according to the target blowout temperature Tof (S701). Next, it is judged whether or not the blower fan voltage setting switch is pressed (S
702), if it is determined that the blower fan motor is pressed, the output value Vfan to the blower fan motor is set to the selected voltage Vf.
The values are set to an and m (S703). On the contrary, when it is determined that the button has not been pressed, the process returns. In the air mix opening process, an example is shown in which the target air conditioning condition is corrected by an amount corresponding to the stored steady-state deviation. However, similar correction control may be applied to this air amount process. it can.

Output Processing FIG. 11 shows the details of the output processing shown in FIG.
First, a drive signal is sent to each actuator of the air mix door, the air outlet mode door, and the air inlet mode door so that the air mix opening X, the air outlet mode, and the air inlet are set in steps S103 to 105. It is output (S801). Next, a drive signal is output to the blower fan motor so that the blower fan voltage Vfan set in step S106 is obtained (S80).
2).

[Second Embodiment] [Correction Executed by Integral Amount of Deviation] This second embodiment is different from the first embodiment only in the air mix opening processing of step S103, and therefore only this portion is shown in FIG.
This will be described with reference to the flowchart of. Note that steps S1001 to S1004 shown in FIG. 13 are the same as steps S401 to S404 shown in FIG. 7, so description thereof will be omitted.

After the calculation of the target outlet temperature, it is judged whether or not the room temperature is stable. Here, the room temperature is stabilized by comparing the integrated average of the room temperature change width within the predetermined time T0 seconds with the predetermined value T02. It is determined whether or not (S1
005). That is, the judgment of the following Expression 2 is executed.

[0050]

[Equation 2]

As a result of the above judgment, if the room temperature is stable, the predicted room temperature Tic, prd is calculated (S1006).
Then, it is determined whether the room temperature is stable (S
1007). That is, the judgment of the following Expression 3 is executed.

[0052]

[Equation 3]

Here, the room temperature Tic within the predetermined time T1 second
By comparing the integrated mean Eic of the deviations between the predicted room temperature Tic and prd with the predetermined value T02, it is determined whether or not the steady-state deviation is large. This Eic is determined by the following Equation 4.

[0054]

[Equation 4]

(Tic-Tic, pr in the above equation
d) i is the i-th room temperature Tic in the past and the predicted room temperature Tic, p
It is the deviation of rd, and N01 is a predetermined constant. After that, the room temperature correction amounts Tic, cor [i] of the storage area i corresponding to the current outside temperature are updated and stored, but the first term on the right side of the expression used for updating is slightly different. That is, Tic, cor '[i] = Wcor × (Eic-Wex
X (B x Tamb + C x Qsun)) + (1-Wco
r) × Tic, cor [i], and the deviation integrated average value Eic obtained in step S1007 is used instead of Tic−Tic, prd in step S408.

After that, the target outlet temperature To after correction
The air mix opening X is obtained from the following formula using f and cor. That is, X = F × Tof, cor ² + G × Tof, cor + H.

As described above, the judgment as to whether the room temperature has entered the stable region and the size of the deviation between the room temperature recognition value and the predicted room temperature are carried out by the amount of integration for a predetermined time, so noise or the like suddenly occurs. It is possible to prevent the correction amount from being updated due to the mechanical deviation.

[Third Embodiment] [Correction Performed by Deviation Average with Several Past Information Stored] This third embodiment is based on the air mix opening shown in step S103 in the first embodiment. Of the temperature processing, only the method of updating the room temperature correction amount map shown in step S408 is different, and only this portion will be described using the flowchart of FIG. When step S408 shown in FIG. 7 is entered, first, the correction amount Cor corresponding to the deviation amount this time is obtained by the following formula (S1101). That is, Cor = Tic−Tic, prd−Wex × (B × Ta
mb + C × Qsun).

Next, the correction amount obtained above is shown in FIG.
It is stored in the area corresponding to the current outside temperature in the deviation information memory having the arrangement as shown in FIG. 5 (S1102). At this time, the data already stored in the deviation information memory is 1
When the number of storable data exceeds Nmem, the oldest data is erased. After that, the deviation information updated in the previous step is averaged by the following equation 5 to obtain the room temperature correction amount Tic, cor [i] (S110).
3).

[0060]

[Equation 5]

Here, W [k] (k = 1, 2, ...,
Nmem) is a weight having a size according to the stored order, and if W [k] = 1 for all W [k], it is a simple addition average of all data. Here, W
The newer [k] is set to a larger value, and the average is set so that the latest information is emphasized. After that, in the storage area i corresponding to the current outside temperature of the room temperature correction map, Tic, cor [i]
And revert to the main flow.

In this embodiment, step S408 in the first embodiment has been described, but the same processing can be applied to step S1008 in the second embodiment. . However, in this case, the Cor calculation formula in step S1101 is changed to the following formula. That is, Cor = Eic−Wex × (B × Tamb + C × Qsu
n).

As described above, the correction amount is determined not only based on the deviation information obtained by one ride, but also based on the deviation information of the past several times. The deviation information can be accurately determined.

[Fourth Embodiment] [Storing Past Information for Each Blowout Mode] In this fourth embodiment, the storage forms of the room temperature correction map and the deviation information memory in each of the above-mentioned embodiments are different, and only this part is provided. explain. In this embodiment, the room temperature correction map and the deviation information memory are stored for each outlet mode as shown in FIG. 16, and when the information is read in step S402 in the first embodiment, Alternatively, when the storage is updated in step S408, the process is executed for the storage area corresponding to the current blowing mode.

As described above, since the deviation characteristic corresponding to the wind direction of the passenger for each outlet mode is stored and the room temperature is corrected by this, the difference in the wind direction according to the outlet mode can be added. Correction with higher accuracy is realized.

[Embodiment 5] [Development of Correction Amount During Control Other Than Room Temperature] In each of the above embodiments, the target outlet temperature Tof was corrected by directly correcting the room temperature recognition value Tic. The present invention is not limited to this, and for example, the equation for calculating the target blow-off temperature Tof, cor is calculated as follows: constant term correction Tof, cor = A × Tptc + B × Tamb + C × Q
sun + D × Tic + E + Ecor (Ecor is a correction value of the constant E) or set temperature correction Tof, cor = A × (Tptc + Tptc, cor)
+ B × Tamb + C × Qsun, etc., and the room temperature correction amount Ti in the first embodiment is changed.
All of c and cor may be replaced with Ecor, Tptc and cor.

In this case, the amount stored in the correction map is replaced with Ecor or Tptc, cor,
The correction amount calculation formula in step S408 is calculated as follows: constant term correction Ecor ′ [i] = Wcor · (Tic−Tic, pr
