Abstract

PURPOSE:To perform stable air conditioning control by controlling a second signal processed to equality or less than to a specified speed of response into a specified state at a time when a deviation between detection information of environmental conditions and a first signal processed to the specified speed of response is under the specified condition. CONSTITUTION:A temperature controlling value of a means 100 doing temperature control in a car room is controlled by a means 110 according to detection information on at least one type of environmental conditions. In this case, the aforesaid detection information is processed by a first means 120 at a specified speed of response, while it is processed by a second means 130 at a speed of response equal to or less than that in the first means 120.

In brief, when a deviation between the said detection information and the signal outputted out of the first means 120 is under the specified condition, a signal value being outputted out of the second means 130 is fixed to a value when specified conditions are materialized, by way of example.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a vehicle air conditioning control device, and particularly to one having a function of processing input signals related to environmental conditions.

(Prior art) Conventionally, as this type of device, for example, the Japanese Patent Publication No. 62580
As shown in Publication No. 4, in an air conditioner that controls temperature control means such as a blower or a heat exchanger according to environmental information such as outside air temperature, the environmental information such as outside air temperature is calculated per unit time. In addition to providing a detection means for detecting the amount of change or the degree of change in the temperature, the environmental information is inputted after being subjected to delay processing according to the detected amount or degree of change, or the amount of adjustment input to the above-mentioned temperature adjustment means is inputted. There is a known system in which the time response of changes is adjusted to prevent the air conditioning state from changing more than necessary due to environmental changes.

(Problem to be Solved by the Invention) However, in the above conventional example, when delay processing is performed depending on the degree of change in environmental information, for example, even if the degree of change in a short time is greater than a predetermined value, the total amount of change is Although it is not necessary to perform the above-mentioned delay processing etc. when the amount of data is small, there is a problem in that even in such a case, the delay processing etc. are performed.

Furthermore, even with a configuration that detects the amount of change, signal detection must be performed for a relatively long time in order to determine whether the amount of change is large enough to require delay processing, etc.; There were problems such as a decrease in performance and a heavy program load for those using microcomputers.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a vehicle air conditioning control device that solves the problems of the conventional example and processes environmental information that affects temperature control according to changes in the environment so as not to impair the air conditioning feeling. It is something to do.

(Means for Solving the Problems) Accordingly, the vehicle air conditioning control device according to claim 1 is provided as shown in FIG.
As shown in FIG. 1, a temperature control means 100 includes at least a blower and a heat exchanger to control the temperature inside the vehicle, and a temperature control amount of the temperature control means 100 is adjusted according to detected information of at least one type of environmental condition. Adjustment amount control means 1 to be set
10, the first signal processing means 120 receives the detected information and outputs it with a predetermined response speed; a second for outputting the input signal to said i) section 4 M II 111 means 110 with a response speed equal to or slower than the response speed in the means 120;
a signal processing means 130, and an operation control means 140 for inputting the detection information and the output signal of the first signal processing means 120 to control the operation of the second signal processing means 130, the first signal processing means 120
If the deviation of the output signal is under a predetermined condition, the output value of the second signal processing means 130 is fixed to the output value when the predetermined condition is met, or the input signal is processed with a response speed that is slower than the normal response speed. The system is equipped with a device that controls the output of the image.

Further, as shown in FIG. 1(b), the air conditioning control device for a vehicle according to claim 2 includes a temperature adjusting means 100 that includes at least a blower and a heat exchanger to adjust the temperature inside the vehicle, and a
In a vehicle air conditioning control device, the air conditioning control device for a vehicle is equipped with an adjustment amount control means 110 that sets a temperature adjustment amount of the temperature adjustment means 100 based on outside air temperature information, and the outside air temperature information is inputted and is controlled at a predetermined response speed. a first signal processing means 120 for outputting, and a second signal processing for inputting the outside air temperature information and outputting an input signal with a response speed equal to or slower than the response speed in the first signal processing means 120. means 130, the outside air temperature information and the output signal of the second signal processing means 130 are input, and after the ignition switch is turned on, the outside air temperature information is inputted until the change in the outside air temperature information satisfies a predetermined condition. a signal selection means 150 that selects and outputs the signal preferentially; and an operation control means that receives the outside air temperature information and the output signal of the first signal processing means 120 and controls the operation of the second signal processing means 130. 140, when the deviation between the outside temperature information and the output signal of the first signal processing means 120 is under a predetermined condition, the output value of the second signal processing means 130 is changed to the output value when the predetermined condition is satisfied. The input signal is controlled to be output at a fixed output value or at a response speed that is slower than the normal response speed.

Further, the signal selection means 150 may preferentially select and output the outside air temperature information t8 until a predetermined period of time has elapsed since the ignition switch was turned on.

(Function) Therefore, the detection information subjected to so-called delay processing is inputted to the adjustment amount control means by the second signal processing means. If the deviation from the processed output signal of the first signal processing means is under certain conditions, the output value of the second signal processing means is fixed or output with a slower response time than usual, so that the detected information This prevents the influence of changes from exerting more influence on the temperature control means than necessary.

In particular, when it comes to information that is easily affected by vehicle exhaust, such as outside temperature information, the adjustment amount control means does not perform signal processing on the detected information until the selection means satisfies a predetermined condition. For example, if a temperature higher than the true outside temperature is detected due to vehicle exhaust gas, etc., this detection information can be used instead, and the second signal processing means and Even if processing is performed such that the outside air temperature is fixed at a high value near the detected outside air temperature due to the action of the operation control means, such a signal will not be input to the adjustment amount control means, and therefore,
The above-mentioned problems can be achieved.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 2, the vehicle air conditioning control device includes an air conditioning duct 1
An intake door switching device 2 is provided on the most upstream side of the intake door switching device 2, and an inside/outside air switching door 5 is disposed at the part where the inside air population 3 and the outside air population 4 are separated. By operating the actuator 6, the air introduced into the air conditioning duct l-1 can be selected between inside air and outside air.

The blower 7 sucks air into the air conditioning duct 1 and blows it downstream, and an evaporator 8 and a heater core 9 are provided behind the blower 7.

An air mix door 10 is provided in front of the heater core 9, and by adjusting the opening degree of the air mix door 10 using an actuator 11, the air passing through the heater core 9 and the air bypassing the heater core 9 are separated. The proportions are now adjusted. Further, on the downstream side of the heater core 9, a defrost outlet 12 and a Ghent outlet 13 are provided.
The mode doors 15a, 15b are provided at the separated portions, and the mode doors 15a, 15b are operated by an actuator 16.1.
The blowout mode can be switched by operating 7.

The actuators 6.11, 16.17 and the motor 7a of the blower 7 are connected to drive circuits 403 to 4, respectively.
It is controlled based on the output signal from the microcomputer 41 via 0d. This microcomputer 41
are central processing unit (CPLI), read-only memory (ROM), and random access memory (RAM) not shown.
, an input/output board (Ilo), etc., and the microcomputer 41 has a vehicle interior temperature TR input from a vehicle interior temperature sensor 42 that detects the temperature inside the vehicle interior.
1 The outside air temperature TA from the outside air temperature sensor 43 that detects the outside air temperature, the solar radiation amount T3 from the solar radiation sensor 44 that detects the amount of solar radiation, and the set temperature T from the temperature setting device 45 that sets the temperature inside the vehicle are multiplexed. The signal is converted into a digital signal and input via 46.

Further, an output signal is inputted to the microcomputer 41 from the operation section 48 . This operation unit 48 is used to switch between automatic control states (AUTO) as the control state of the air conditioner.

OR) 5 changeover switch, a switch for manually setting the speed of the blower 7, etc. (not shown).

Next, the basic control of this apparatus by the microcomputer 41 mentioned above will be explained with reference to the main flowchart shown in FIG.

First, the microcomputer 41 starts execution at step 200, and proceeds to step 202 to initialize various variables, flags, etc.

In the next step 204, the above-mentioned vehicle interior temperature sensor 42
Detection signals and the like are inputted from etc., and the process proceeds to step 206. In step 206, the target blowout temperature X8 of the air blown into the vehicle interior is calculated using the detection signal input in step 204, for example, according to the following equation.

χM・A・T, +B−T, child C−T, +D−Ts−A−
TosuE However, A, B, C, and D are calculation coefficients, and E is a calculation constant. Further, T is a set temperature, T is a vehicle interior temperature, TAD is an outside temperature for control which will be described later, and T is a solar radiation amount.

Then, the process proceeds to the next step 300, where the opening degree of the air mix door 10 is calculated with respect to the above-mentioned target blowout temperature XH, and the air mix door 10 is rotated via the drive circuit 40b so as to achieve this opening degree. . Here, target blowing temperature X,
The opening degree of the air mix door lO with respect to RO degree characteristics
Opening degree control is performed using M-shaped valves.

Thereafter, the processing in steps 400 to 700 is basically the same as in the case of step 300 described above.
, the mode doors 15a, 15b, and the inside/outside air switching door 5). In step 700, after controlling the drive of a compressor (not shown) based on the above-mentioned target blowout temperature, the process returns to step 204 and the above-described process is repeated.

FIG. 4 shows a control routine for outside air temperature processing that is carried out as part of the target air temperature calculation in step 206 described above, and its contents will be explained below with reference to the same figure.

First, the microcomputer 41 starts execution at step 208 and proceeds to step 210 to determine whether the ignition switch (not shown) has been turned from off to on. If it is determined that the switch has been made from off to on (YES), the process proceeds to step 212;
Otherwise (No), that is, after the ignition switch is once turned on, the process proceeds to step 228.

Here, it is determined whether the ignition switch is on or off because the operation of the air conditioner is linked to the on/off state of the ignition switch.

In step 212, the detected value T of the outside air temperature sensor 43 is input, and the outside air temperature variable TA (N-0 is set to the detected value TA).
is set, and the process proceeds to step 214. In step 214, FLAGI to FLAG3 are set to zero. Here, F.L.
AGI is called an outside air temperature sampling timer flag, and when inputting the outside air temperature detection value from the outside air temperature sensor 43, it is performed at every predetermined timer time as described later, and it is checked whether this timer is in operation or not. It is set to "1" while the timer is operating.

Further, FLAG2 is used to display whether or not a control outside air temperature TAD, which will be described later, is in a fixed state, and is set to "1" while TAD is in a fixed state. Furthermore, FLAG3 is an outside air temperature reset flag for judgment criteria.
As will be described later, outside air TAB for judgment criteria is T under specified conditions.
"1" is set except when it matches AD.

After step 214 described above, proceed to step 216 and T
Determine whether A > TA (N-11. In other words, in this step immediately after starting the device, TA, T T□1., where the detected outside air temperature TA is substituted with the detected outside air temperature TA at the time of the previous process execution.

It has the meaning of determining whether it is larger than the other.

And if TA is greater than TA(N-11) (YE
In step S), the process proceeds to step 218, sets FLAGφ to "1", and proceeds to step 224. Here, FLAGφ is used to display whether or not the detected outside air temperature TA is used as is for the outside air temperature TAll for judgment reference, and for a predetermined period after the ignition switch is turned on, T s m = T
A, and zero is set in FLAGφ.

In this way, T AM = T A is set because, for example, when the vehicle stops after traveling for a certain amount of time and the ignition switch is turned on again while the vehicle is stopped, the residual heat of the engine causes the surroundings of the outside temperature sensor 43 to rise while the vehicle is stopped. The temperature may be rising, causing you to enter a value higher than the actual outside temperature. In this state, the outside air temperature T, o for control, which will be described later, is
If control is performed to change the temperature according to the comparison between the judgment reference outside temperature TAIl and the detected outside air temperature TA, the engine will be cooled due to the operation of the radiator fan (not shown) etc. when the device is started. Since the temperature around the outside air temperature sensor 43 is rapidly approaching the actual temperature, the TAD is fixed at a certain value higher than the actual outside air temperature.

For this reason, the temperature of the blown air may drop more than necessary and the air volume of the blower 7 may also become large. Therefore, in order to avoid such a situation, after turning on the ignition switch, do not turn on the T until the predetermined conditions are satisfied.
As=TA.

For this reason, in step 220, step 2
As mentioned above based on the result of the judgment in step 16, it is assumed that the temperature near the outside air temperature detector 7, which has increased due to engine residual heat, is gradually approaching the actual temperature.
LAGφ is set to zero. And step 222
Proceed to outside air temperature variable TA (detected outside air temperature TA in 8-11)
Set.

In step 224, TA is set to the control outside air temperature TAI, and in step 226, the judgment reference outside air temperature TAX, which will be described later, is
TA is set in I, respectively, and the process returns to the main routine via step 278.

On the other hand, in the stem knob 228, FLAGφ is “1”.
”, and if it is “1” (YES), the process proceeds to step 234, and if it is not “1” (NO), the process proceeds to step 214 described above.

In step 232, a timer is started for determining a predetermined time interval for updating the determination reference outside air temperature TA and the control outside air temperature TAIll, which will be described later, and FLAG is set to "l", and the process proceeds to step 234. Step 23
In step 4, it is determined whether or not the elapsed time since starting the evening/immediate timer in step 232 described above has exceeded 60 seconds, and if t exceeds 60 seconds (YES), step 2
Proceed to step 40, and if it has not exceeded <NO), proceed to step 23
Proceed to 6 and set "1" to FLAG2. FL
AG3 is both set to zero and the process advances to step 238.

Then, the current TAB value is set as the control outside air temperature TAD, that is, TAD is maintained as it is, and the process returns to the main routine via step 27B.

On the other hand, in step 240, in response to the timer time t exceeding 60 seconds, FLAGl is set to zero, and step 2
Proceed to 42 and lTa-Tag! >a (YES
), that is, the detected outside air temperature TA and the outside air temperature TA for judgment criteria.
If the difference from II is greater than the predetermined value a('C), proceed to step 244; if ITATAR>a is not (No)
proceed to step 240, respectively.

At step 244, FLAG3 is set to zero and the process proceeds to step 246. Also, in step 260, l TA
- TA, determine whether j > b (a >b);
If IT^-TAa l > b (YES), that is, if the difference between the detected outside air temperature TA and the judgment reference outside air temperature TA11 is greater than or equal to the predetermined value b ('c) (however, a>b
(If I TATAI 1>b is not satisfied (NO), the process proceeds to step 262.

In step 246, it is determined whether FLAG2 is "1" or not. If FLAG2=1 (YES), the process proceeds to step 250, and if FLAG2 is not "1" (No
) proceeds to step 248, sets the variable N to zero, sets FLAG2 to "1", and proceeds to step 250.

In step 250, the current value of N is set to 1.
The added value is newly set as N, and the process proceeds to step 252. At step 252, the value of TAD is held at the current value, and the process proceeds to step 254.

In step 254, it is determined whether T,>TAIl, and if TA>TAIl (YES), step 256
Then, add the value of NxC (C is the predetermined temperature of the sheep position) to TAD and set this to 'T'Aa. Also, TA〉TA
If it is not l (NO), proceed to step 258 and TAI
, the value of NXC is subtracted from the value of NXC, and this is set to TAIl. After step 256 or step 258, the process returns to the main routine via step 278.

On the other hand, in the case of No in step 260, the process proceeds to step 262, sets FLAG'2 to zero, and proceeds to step 264. In step 264, FLAG
If FLAG 3 is "1" (YES), go directly to step 268; if not "1" (No), set variable N to zero in step 266 and set FLAG3 to Step 2 after setting “1”
Proceed to step 68 respectively.

In step 268, after setting N+1 to a new N, the process proceeds to step 270, where it is determined whether the detected outside air temperature TA is greater than the control outside air temperature TAD.

Then, if T,〉TAI, (YES), step 2
The process proceeds to step 72, where the value obtained by adding the NXC value to the current TAn is set as a new TAD value, and the process proceeds to step 276.

Also, if TA>TAD is not the case (NO), step 27
The process proceeds to step 4, where the value obtained by subtracting NXC from the current TAD is set as a new TAoO value, and the process proceeds to step 276.

In step 276, steps 272 or 2 described above are performed.
At step 74, the updated value of TAI is set to TAll, and the process returns to the main routine via step 1278.

Next, the operation of this device will be comprehensively explained with reference to FIG. 6.

First, FIG. 6 shows the TAB, etc. when this device starts processing the outside air temperature when the area around the outside air temperature sensor 43 is higher than the actual outside air temperature due to engine residual heat before the ignition switch is turned on. It is an explanatory diagram of the change, and a relatively high value is detected based on the above-mentioned preconditions when the ignition switch is turned on.

After the ignition switch is turned on, the radiator fan (not shown) etc. operate, so the temperature around the outside air temperature sensor 43 gradually decreases and approaches the actual outside air temperature (Fig. 6, ICON). to time T). During this time, the processes from step 1210 to step 226 in the aforementioned flowchart are performed, and the detected outside air temperature T is directly substituted for the control outside air temperature TA (see step 226), so that the target blowout temperature is The calculation will be performed using the detected outside air temperature TA.

Then, when it is confirmed that the detected outside air temperature T, has started to rise again, the outside air temperature TAR for judgment and the outside air temperature TAD for control are changed to a predetermined temperature α(' C) (between time T1 and T2 in Figure 6).

Here, as shown in FIG. 6, a case where the temperature once drops rises again is considered to be, for example, a case where the vehicle remains stopped even when the ignition switch is turned on. The above-mentioned process includes steps 216, 218-226, and step 2 in the flowchart of FIG.
28 to 256.

After lTA TAal>a holds true at time T2, TAII increases by α('C) every 60 seconds as before, but TAD increases by TA-TA
It will be fixed to the value at the time when II>a holds (
(See step 252 in FIG. 4).

Therefore, during this period, the same value is used for TAI in calculating the target blowout temperature X9. In FIG. 6, TA and TAo are represented by solid lines, and TAB is represented by dotted lines.

After this, the detected outside air temperature TA decreases and ITATAa
When l > b (provided that l TA TA II l > a does not hold) (Figure 6, time T3
), thereafter TA! l is again changed from the previous fixed value to α(C
), and at the same time TAIl is increased by TA
It is assumed to be the same as the value of D. These processes are executed by steps 260 to 276 in the flowchart of FIG.

Here, the case where the TA suddenly decreases as shown in FIG. 6 is, for example, a case where a vehicle that was previously stopped starts traveling.

Then, when TA falls further and becomes lower than TAD, TA
D is decreased by α (°C) every 60 seconds, and Ta
When TAD l > a holds true (time T in Figure 6),
While fixing TAD as in the process at time T2,
'rA@ will continue to be decreased by α (°C). (See step 274 in Figure 4).

Incidentally, from this point on, basically the same processing as the processing from time T2 to T3 is repeated, so the explanation thereof will be omitted.

FIG. 5 shows a second embodiment of the outside air temperature treatment as a flowchart, and the same processing steps as in the previous embodiment are given the same numbers as in FIG. 4, and their explanations are omitted. In the following, only the boundary will be explained with reference to the same figure.

This second embodiment differs from the previous embodiments in that, as a condition for starting the process of changing TAD by α (°C), in the previous embodiments, TA>TA(N-1
However, in this example, a timer is provided and Tao is set to α after a predetermined timer period has elapsed.
The reason is that ('c) is changed one by one.

Therefore, in step 213, a timer is started, and in step 217, it is determined whether the elapsed time t from the start of the timer has passed 120 seconds,
After t > 120 seconds, T
AD and TAB are increased by a predetermined amount.

Looking at this in FIG. 6, according to the first embodiment, time T1
, which used to change variously depending on changes in the detected outside air temperature, is fixed at 120 seconds according to this second embodiment.

In the first and second embodiments, the predetermined elapsed time in step 234 was set to 60 seconds, but it is not limited to this value and may be arbitrarily set to any other value. .

Further, in the second embodiment, the predetermined time in step 217 is not particularly limited to this value, and may be set to any other value.

Furthermore, in this embodiment, the times for periodically increasing and decreasing TAB and TADO are the same, but they do not necessarily have to be the same; for example, the synchronization time for increasing and decreasing TAD is
It may be longer.

(Effect of the invention) Since the present invention is configured as described above, the temperature: A prefix also does not change suddenly due to a sudden change in the detection information, and the feeling of the sky 11 is not spoiled. If the detected information changes by a predetermined amount due to the vehicle entering and exiting the tunnel, the second
Since the output value of the signal processing means is fixed or outputted with a longer delay time than usual, sudden changes in the air conditioning condition can be more effectively prevented and stable air conditioning control can be obtained.

In addition, the detected information is not used as is for temperature control, except in certain cases immediately after the ignition switch is turned on, but it is subjected to signal processing, so the sensor can detect changes over time due to environmental conditions, etc. It does not need to be an expensive sensor that has a special coating or the like to reduce the amount of damage caused by the noise, and an inexpensive sensor can be used to reduce the cost of the device.

Furthermore, if the detected information is used as is from the time the ignition switch is turned on until a predetermined condition is satisfied, for example, if a temperature higher than the true outside temperature is detected after the ignition switch is turned on, and then the detected temperature drops. The operation control means prevents the output value of the second signal processing means from being fixed at a temperature higher than the true outside air temperature, thereby providing a more comfortable air conditioner. be.
