Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle air-conditioning control device, and particularly to improve the suitability of learning control.
[0002]
[Prior art]
As disclosed in Japanese Patent No. 3111566, for example, a conventional vehicle air conditioning control device relates an applied voltage (air flow rate) of a blower in an air conditioner to a predetermined control characteristic (an amount of solar radiation and an applied voltage). Control) and the signal set by the manual operation of the occupant. In addition, if the occupant's manual operation (air flow rate switch) is turned on, the amount of solar radiation at that time and the application By learning the voltage and changing the control characteristics, it is possible to control the amount of air blown according to the passenger's preference according to the increase or decrease of the amount of solar radiation.
[0003]
[Problems to be solved by the invention]
However, as shown in FIG. 10, the above control characteristics are obtained by dividing the entire area where the amount of solar radiation can be easily divided into areas having a uniform width, and applying the applied voltage to each divided area. Therefore, the situation of manual operation of the occupant with respect to the amount of variation in the amount of solar radiation differs between the divided region on the side where the amount of solar radiation is large and the divided region on the side where the amount of solar radiation is large, resulting in a situation where learning of the air flow control characteristics is not properly performed .
[0004]
That is, as shown in FIG. 11, as if 0~1000W / m ² the entire area may take the solar radiation, between the dividing 5, etc., if you set the divided areas by 200 W / m ^2, a lot of insolation Even if the amount of solar radiation fluctuates from 800 to 950 W / m ^{2 in} the region of 800 to 1000 W / m ² , the sensation does not change much, but 0 to 150 W in the region of 0 to 200 W / m ² where the amount of solar radiation is small. When the amount of solar radiation fluctuates to / m ² , the amount of fluctuation (150 W / m ² ) varies greatly as a passenger's feeling despite being the same as above.
[0005]
Therefore, even if the amount of sunshine is 0 W / m ² , even if the amount of air blow suits your preference, if the amount of sunshine is 150 W / m ^2, you will manually set the air amount to feel unsatisfactory and increase the amount of air blow. The control characteristics are learned so that the air flow increases. However, at the next boarding and when the solar radiation amount is 0 W / m ² , due to the control characteristics learned last time, the air flow rate will be too large, and the manual setting will be made so as to reduce the air flow rate. Repeat happens.
[0006]
In this way, if the solar radiation amount division region is set evenly, in the region where the solar radiation amount is small, it cannot be converged to the control characteristics that suit the passenger's preference, and manual operation is required each time the solar radiation amount fluctuates. turn into.
[0007]
To prevent this, it is possible to converge to control characteristics that suit the passenger's preference by increasing the number of divisions of solar radiation and learning finely, but increasing the number of divisions leads to an increase in memory and calculation. This leads to an increase in time.
[0008]
In view of the above problems, an object of the present invention is to provide a vehicle air-conditioning control apparatus that can perform appropriate learning control without increasing storage capacity and calculation time.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention employs the following technical means.
[0010]
In the first aspect of the present invention, an operating part (27) provided in the air conditioner (20) and operating to function the air conditioning, an environmental condition detecting means (35) for detecting an environmental condition of the vehicle, A control characteristic storage means (31a, 31b) for storing a control characteristic, which is a relative relationship between the condition and a control amount to the operating unit (27), and an environmental condition detected by the environmental condition detection means (35) are controlled. Control amount determination means (S430, S460) for determining the control amount based on the characteristics, control amount manual setting means (371) for the passenger to manually set the control amount, control amount determination means (S430, S460), and control amount Controlled by a drive means (30) for controlling the drive of the operating portion (27) based on each output signal of the manual setting means (371), and a control amount manual setting means (371) under a predetermined environmental condition among the control characteristics. Amount changed In the vehicle air-conditioning control device having the control characteristic changing means (S450) for changing the control characteristic when the control characteristic is stored, the control characteristic stored in the control characteristic storage means (31a, 31b) Divided into a plurality of divided areas, the control amount is related to each divided area, and the width of the divided area of the environmental condition is set to two or more different sizes ,
The width of the divided area of the environmental condition set by the control characteristic storage means (31a, 31b) is characterized by being made smaller according to the frequency of use of the vehicle with respect to the environmental condition .
[0011]
As a result, by weighting the area that requires learning accuracy in the entire area that can be taken by the environmental conditions and reducing the division width of that area, it is possible to perform fine learning control, and Control that suits your preferences is possible. In this case, since the number of divisions is not increased, the memory capacity is not increased and the calculation time is not increased.
[0012]
In the invention according to claim 2, in the vehicle air conditioning control device, the control characteristics stored in the control characteristics storage means (31a, 31b) are divided into a plurality of divided areas, and the entire area that the environmental condition can take is divided into the divided areas. The control amount is related to each area, and the width of the divided area of the environmental condition is set to two or more different sizes,
The width of the divided area of the environmental condition set by the control characteristic storage means (31a, 31b) is reduced according to the operation frequency of the occupant control amount manual setting means (371) for the environmental condition . .
[0013]
Thereby, the same effect as that of the first aspect of the invention can be obtained.
[0018]
In addition, the code | symbol in the bracket | parenthesis of each said means shows a corresponding relationship with the specific means of embodiment description mentioned later.
[0019]

[0025]
The air volume of the blower 27 in the air conditioning unit 20 and the opening degrees of the various doors 22a, 22b, 22c, 22d, and 22e are controlled by the control device 30A. Specifically, it is controlled through a voltage controller and an actuator (not shown) by a drive circuit 30 as drive means based on an output signal from the microcomputer 31 in the control device 30A.
[0026]
The microcomputer 31 includes a central processing unit (CPU), an I / O port, an A / D conversion function, a ROM 31a, a RAM, a standby RAM 31b, and the like (not shown), which are known per se. Note that the control characteristic storage means in this embodiment corresponds to the ROM 31a and the standby RAM 31b.
[0027]
The standby RAM 31b is a RAM for storing (backup) various signals and control characteristics described later even when the ignition switch (hereinafter referred to as IG switch) is off. Power is supplied directly without intervention. Further, even if the power is removed from the battery, the microcomputer 31 is constituted by a backup power source (not shown) that supplies power to the microcomputer 31 in a short time. The control characteristic storage means may be a non-volatile memory having its own memory holding capability such as a flash memory.
[0028]
The ROM 31a stores various control characteristics as initial characteristics.
Specifically, it is the inside / outside air mode control characteristic by opening / closing the inside / outside air switching door 22a, the opening degree control characteristic of the air mix door 22b, and the blowing mode control characteristic by opening / closing the defroster door 22c, face door 22d, and foot door 22e. These control characteristics are determined in advance so as to change according to a target blowing temperature TAO described later. Similarly, the ROM 31a stores an applied voltage control characteristic applied to the blower 27 as an initial characteristic, which will be described later in detail.
[0029]
Environmental conditions that affect the air conditioning in the passenger compartment are input to the microcomputer 31 via the respective level conversion circuits 32 by the inside air temperature sensor 33, the outside air temperature sensor 34, and the solar radiation sensor 35 as environmental condition detecting means. Is A / D converted by the microcomputer 31 and read as an environmental condition signal. The passenger's favorite temperature is input by the temperature setting switch 36, input through the level conversion circuit 32 as described above, A / D converted by the microcomputer 31, and read as a set temperature signal.
[0030]
Further, an output signal from the operation unit 37 is input to the microcomputer 31. The operation unit 37 includes an AUTO switch (not shown) for setting an automatic control state, a manual air supply amount changeover switch 371 as a control amount manual setting means, a manual inside / outside air changeover switch, a manual blowout mode changeover switch (face, bilevel, foot, foot differential). , Defroster) and the like.
[0031]
The details of the manual air flow rate changeover switch 371 among the above switches will be described with reference to FIG. The manual air flow rate changeover switch 371 is composed of four switches: a low switch 371a, a down switch 371b, an up switch 371c, and a high switch 371d. Of these, the low switch 371a is configured to output a signal for controlling the voltage applied to the blower 27 to 4 volts (minimum voltage) when pressed. The high switch 371d is configured to output a signal for controlling the applied voltage to 12 volts (maximum voltage) when pressed.
[0032]
The down switch 371b outputs a signal that lowers the applied voltage by a predetermined voltage (0.25 volts) when pressed, and the up switch 371c reduces the applied voltage by a predetermined voltage (0.25 volts) when pressed. ) It is configured to output a raising signal.
[0033]
Next, the overall control of the air conditioning unit 20 by the microcomputer 31 will be described with reference to FIG. 3, and then the learning control of the blower 27 will be described with reference to FIGS. 4 to 6 including the contents of the applied voltage control characteristics. .
[0034]
First, as shown in the flowchart of FIG. 3, the microcomputer 31 starts control in step S100 when the IG switch of the vehicle is turned on, proceeds to step S110, and sets initial values such as various conversions and flags.
[0035]
In step S150, environmental conditions are input from sensor signals from the inside air temperature sensor 33, the outside air temperature sensor 34, and the solar radiation sensor 35, and the state of the operation switch is input from the temperature setting switch 36 and the operation unit 37.
[0036]
Next, the process proceeds to step S200, and a target blowing temperature TAO (hereinafter referred to as TAO) of air blown into the vehicle interior is calculated according to the following equation 1 from various environmental conditions and set temperatures among the input signals in step S150.
[0037]
(Formula 1)
TAO = KSET × TSET-KR × TR-KAM × TAM-KS × TS + C
However, KSET, KR, KAM, and KS are coefficients, C is a constant, TSET is a set temperature, TR is an inside air temperature, TAM is an outside air temperature, and TS is an amount of solar radiation.
[0038]
In step S300, the opening degree of the air mix door 22b corresponding to TAO is calculated from the opening degree control characteristic stored in the ROM 31a in advance, and an actuator (not shown) is controlled via the drive circuit 30 so as to be this opening degree. The temperature of the air blown out from each outlet into the passenger compartment is controlled.
[0039]
Next, it progresses to step S400, the voltage applied to the air blower 27 is calculated, the air blower 27 is driven via the drive circuit 30, and the air volume blown out into the vehicle interior is controlled. It is difficult to determine the applied voltage (that is, the amount of air flow) using uniform applied voltage control characteristics because there are individual differences in the amount of air flow preferred by the occupant. Here, manual operation of the occupant's manual air amount switching switch 371 is difficult. Accordingly, the applied voltage control characteristics are learned so as to obtain a desired blowing amount, and appropriate learning control is performed. Details of this will be described later.
[0040]
In step S500, an inside / outside air mode corresponding to TAO is calculated from inside / outside air mode control characteristics stored in the ROM 31a in advance, and an actuator (not shown) that drives the inside / outside air switching door 22a is controlled via the drive circuit 30. To do.
[0041]
Next, in step S600, the blowing mode corresponding to TAO is calculated from the blowing mode control characteristics stored in advance in the ROM 31a, and an actuator (not shown) that drives the defroster door 22c, face door 22d, and foot door 22e is driven by the drive circuit 30. Control through.
[0042]
In step S500 and step S600, when each mode is manually selected by each changeover switch of the operation unit 37, each door 22a, 22c to 22e is controlled so as to be in the selected mode.
[0043]
In step S700, a compressor (not shown) is controlled. After the process of step S700, the process returns to step S150 to read various signals again, and the air conditioning control is repeated in steps S150 to S700.
[0044]
Next, based on the flowchart shown in FIG. 4 together with the details of the learning control (step S400) of the blower 27 as the main part of the present invention, together with the applied voltage control characteristics of the blower shown in FIGS. I will explain.
[0045]
First, applied voltage control characteristics will be described. The applied voltage control is applied to the doors 22a to 22e whose mode control characteristics and opening degree control characteristics are related to TAO (a comprehensive variable depending on the set temperature, internal air temperature, external air temperature, and solar radiation amount). The characteristics are such that the inside temperature, outside temperature, and solar radiation are related as independent variables to better fit the passenger's feeling. That is, as shown in FIG. 5 (a), the map is divided by the amount of solar radiation and the outside air temperature to determine the current environment area, and as shown in FIG. 5 (b), it corresponds to each environment area of this map. It is composed of applied voltage characteristics with respect to the inside air temperature and the amount of solar radiation.
[0046]
The applied voltage characteristics shown in FIG. 5 (b) are shown in (1), (2), (3), (4), indicated in FIG. 5 (b) in a predetermined region width (temporarily A region) of the amount of solar radiation. It is expressed as an equation relating to the five planes (5). When the applied voltage is BLW, these five equations are determined by the following formulas 2 to 5.
[0047]
(Formula 2)
BLW = Hc in (1)
However, Hc is a constant (here, Hc1 to Hc5) that is different for each divided region of the solar radiation amount to be described later, and is updated by learning.
[0048]
(Formula 3)
BLW = Hw in (5)
However, Hw is a constant (here, Hw1 to Hw5) that is different for each divided region of the solar radiation amount to be described later, and is updated by learning.
[0049]
(Formula 4)
BLW in (2) and (4) = a × TR + b × TAM + c × TS + d
However, a, b, c, and d are constants updated by learning. Note that TR, TAM, and TS are the inside air temperature, the outside air temperature, and the amount of solar radiation described in Formula 1, respectively.
[0050]
(Formula 5)
BLW = L in (3)
However, L is a constant (L1 to L5 here) that is different for each divided region of the solar radiation amount to be described later, and is updated by learning.
[0051]
The equations {circle around (1)} to {circle around (5)} concerning these five planes are provided for each divided region of the solar radiation amount as A, B, C, D and E.
[0052]
Hereinafter, in order to facilitate understanding, among the equations (1) to (5) relating to the five planes, the portion (3) will be described as a representative example with reference to FIG. FIG. 6 is a projection of the plane equation (3) on a two-dimensional plane indicated by the amount of solar radiation and the applied voltage. Here, the divided areas of solar radiation will be described.
[0053]
In order to simplify various calculations related to control, the entire area that the solar radiation amount can take is divided into five areas (A to E above). Each of the divided areas corresponds to a divided area in the present embodiment. Then, the interval width of the division is set to two or more different sizes as compared with the uniform width in the prior art. Specifically, the region where the occupant can easily feel the change in the amount of solar radiation is made smaller. That is, the width of the divided area is set to be smaller as the area has a smaller amount of solar radiation. In the actual setting, the division area is determined to increase exponentially as the amount of solar radiation increases.
[0054]
The applied voltage BLW (L1 to L5) is set as an initial characteristic for each divided region of the solar radiation amount, and is stored in the ROM 31a in the microcomputer 31.
[0055]
Based on the content of the applied voltage control characteristics described above, details of step S400 related to learning control of the blower 27 will be described below with reference to the flowchart of FIG.
[0056]
First, in step S410, the current environmental region is determined from the outside air temperature and the amount of solar radiation input in step S150. That is, in the map shown in FIG. 5A, an applied voltage characteristic (FIG. 6) corresponding to the outside air temperature TAM1 at that time is called from the ROM 31a. Although the applied voltage characteristic is originally FIG. 5B, FIG. 6 omits the internal air temperature condition for simplicity of explanation.
[0057]
Next, in step S420, it is determined whether or not there has been a manual operation by the occupant on the manual air flow rate changeover switch 371. If it is determined that the manual operation has not been performed, the process proceeds to step S430, and the applied voltage BLW (any one of L1 to L5) corresponding to the amount of solar radiation at this time is calculated as the control amount, and the drive circuit 30 is calculated in step S440. Output.
[0058]
On the other hand, if it is determined in step S420 that the occupant has manually operated the manual air supply amount changeover switch 371 of the operation unit 37, the applied voltage characteristic is changed (learned) in step S450. The learning method uses a method in which a voltage value input by manual operation and an applied voltage BLW (any one of L1 to L5) as an initial characteristic are changed to an equation that approximates a least square. The changed applied voltage characteristics are stored in the standby RAM 31b. Note that the voltage value data by manual operation of the occupant is taken and stored in the standby RAM 31b in time series, and the manual operation data of the occupant increases each time this flow is performed, and the minimum 2 The applied voltage characteristic is further changed to a value close to the manual operation value of the passenger so as to approximate the power.
[0059]
Next, in step S460, based on the changed applied voltage characteristics, the applied voltage of the divided region corresponding to the amount of solar radiation at this time is calculated as a control amount, and is output to the drive circuit 30 in step S440.
[0060]
In the present embodiment, the control characteristic changing means corresponds to step S450, and the control amount determining means corresponds to steps S430 and S460.
[0061]
The configuration and operation in the first embodiment have been described above. The operation and effect will be described below.
[0062]
In the applied voltage control characteristics, weighting of areas that require learning accuracy is performed in the entire area that can be taken by the amount of solar radiation as an environmental condition, and the division width of the area is set to be small. Fine learning control is possible, and control that suits the passenger's preference is possible. In this case, since the number of divisions is not increased, the memory capacity is not increased and the calculation time is not increased.
[0063]
Specifically, in the present embodiment, the present invention is applied to the learning control of the applied voltage of the blower 27 with respect to the solar radiation amount among various environmental conditions, and the divided region is usually used in the region where the passengers are sensitive to the solar radiation amount. Is set to be small, the applied voltage characteristics are learned in accordance with the manual operation of the occupant, and this learning makes it possible to reliably obtain the desired air flow rate.
[0064]
In addition, since the width of the solar radiation amount divided region is set so as to increase exponentially with respect to the solar radiation amount, the control characteristics can be easily programmed.
[0065]
In the present embodiment, among the applied voltage characteristics, the equation relating to the plane of (3) indicated in FIG. 5B has been described as a representative example, but other equations relating to the plane of (1) and (5) are explained. You may make it respond | correspond. Further, the equations relating to the planes (2) and (4) can be similarly dealt with by setting a to d to be different constants for each divided region of the solar radiation amount. Furthermore, although the equation relating to the plane of (3) is a step-like characteristic indicated by BLW = L (L1 to L5), it may be a characteristic that is continuous with each other as an equation having a gradient.
[0066]
(Second Embodiment)
In the second embodiment, the method of setting the solar radiation amount divided region is changed from the first embodiment.
[0067]
In the said 1st Embodiment, although it set so that the division area by the side with little solar radiation amount as an environmental condition might become small, it was made to make it small according to the usage frequency of the vehicle with respect to an environmental condition, an environment, You may make it make small according to the operation frequency of the manual ventilation volume changeover switch 371 of the passenger | crew with respect to conditions.
[0068]
In other words, when setting the divided areas in accordance with the frequency of use of the vehicle, for example, as shown in FIG. 7, in the relationship between the amount of solar radiation and the boarding time, the area of the amount of solar radiation with high boarding frequency (here, areas 1 to 4). Should be divided into smaller parts.
[0069]
In addition, when setting the divided areas according to the operation frequency of the manual airflow changeover switch 371 of the occupant, as shown in FIG. 8, in the relationship between the amount of solar radiation and the number of operations, an area with high operation frequency (here, area 2). 3) should be divided into smaller parts.
[0070]
Thereby, the effect similar to the said 1st Embodiment can be acquired.
[0071]
(Other embodiments)
In the said 1st Embodiment, although demonstrated as what was applied to the air blower 27 as an action | operation part of the air conditioner 20, it is good not only for this but various doors 22a-22e. In this case, the opening control characteristics and mode control characteristics of the various doors 22a to 22e are related to independent environmental conditions such as the outside air temperature, the inside air temperature, and the amount of solar radiation with respect to those related to the TAO. And
[0072]
For example, in the opening control of the air mix door 22b, as shown in FIG. 9, there is one that incorporates learning control into a set temperature map divided by the outside air temperature and the amount of solar radiation. That is, in this map division, the division width on the side where the amount of solar radiation is small is provided small. Then, the initial set value of the set temperature is assigned in advance so as to be 25 ° C., for example, the solar radiation amount and the outside air temperature are set in the TS1 and TAM2 sections by the manual operation of the passenger temperature setting switch 36, for example. The learning is changed so that the temperature becomes higher. Thereby, if the opening degree of the air mix door 22b is controlled so as to correspond to the learned set temperature, the air temperature can be adjusted to the passenger's preference.
[0073]
The environmental conditions for setting the widths of the divided areas to be different are not limited to the amount of solar radiation, and may be applied to the outside temperature and the inside temperature.
