Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a car air conditioner control device having a troll panel and capable of independently controlling room temperature.

Recently, one-box type leisure vehicles have become widely used, and air conditioning systems are now installed independently in the front and rear seats. However, each air conditioner had its own control panel, and the air conditioning was controlled manually, which required extremely troublesome operations to create a comfortable cabin.

The present invention allows the control unit to independently control the amount of heat supplied to each air conditioning zone from various information including signals from the setting device and room temperature detector, thereby automatically adjusting the temperature of each air conditioning zone to the room temperature set by each setting device. Therefore, the air conditioning can be controlled independently according to each passenger's preference.Furthermore, in case there are a small number of passengers and it is not possible to operate all the controls, all springs μ can be controlled at once on one control panel. It is an object of the present invention to provide a system that is provided with an operating mechanism for control and that allows easy control of all air conditioning zones.

The present invention will be explained below with reference to embodiments shown in the drawings. Fig. 1 is a layout diagram of an air conditioner showing an embodiment of the system.
There is an air conditioner installed at the front desk that can heat the room.
2 is a cooling-only air conditioner installed at the rear of the car.
3 is a heating-only air conditioner installed at the rear. As shown in FIG. 2, the air conditioner 1 is equipped with a blower 4 for blowing air, an evaporator 5 for cooling the blowing air, a heater core 6 for heating, and an air mix damper 7 for adjusting the ratio of the cooling and heating air. There is. Also, inside the air conditioner 2, there is a blower 8, which serves as a reservoir for blowing air, and a rear evaporator 9, which discharges the blown air. It has a rear heater core 11 that heats the blown air.

In FIG. 2, reference numeral 12 denotes high-pressure piping of the refrigeration cycle (not shown), which includes a front refrigerant valve (electromagnetic valve) 13 and an expansion valve 14 that control the flow of refrigerant to the evaporator 5, and a high-pressure pipe that controls the flow of refrigerant to the rear evaporator 9. A ventilator valve (
It has a solenoid valve) 15 and an expansion valve 16τ. 17 is a piping for engine cooling water sent by a walk pump (not shown), and a water pulp (electromagnetic valve) 18 for controlling the flow of hot water to the heater core 6 and rear heater core 11. +7. 20 is a clutch of the refrigeration cycle compressor.

21. 22 is a room temperature center that detects temperatures TrF and TrR at multiple points in the vehicle interior and generates a room temperature signal. 21 is installed at a position where the front is not exposed to sunlight, and 22 is installed at a position where there is no sunlight at the rear. There is. 23 is an outside air sensor that detects the outside temperature T, a m f, and 24.25 is the amount of solar radiation S at the front and rear of the passenger compartment.
The solar radiation sensors detect F and SR, and FIG. 1 shows the positions of the respective air conditioners 1 to 3 and sensors 21 to 25.

26 is the outlet air temperature TEF of the front evaporator 5.

27 is the temperature TER of the air blown from the rear evaporator 9.

28 is a temperature sensor that detects the temperature THR of the air blown from the rear heater core 11 and generates a signal.

43 is a curtain 433 that partitions the front seat and the rear seat shown in FIG.
are closed and the front and rear seats are separate spaces.
A limit switch, for example, is a sensor that detects whether the curtains are open and the front and rear seats constitute one space, depending on whether the curtains are open or closed. In other words, the heat load on the air to be conditioned 1111 is different when the curtains are open and when they are closed, so in order to maintain the room temperature at the set room temperature, it is necessary to switch the capacity of each air conditioner according to the state. The sensor 43 is used as a sensor to detect the state.

As will be explained later in this embodiment, when the front and rear air conditioners are operated simultaneously, the effect on the vehicle heat load due to opening and closing of the curtains is smaller than when the front and rear air conditioners are operated independently. Therefore, we decided not to change the air conditioner capacity by opening and closing the curtains. However, if more precise room temperature control is required, the air conditioning capacity may be changed as necessary. The curtain 433 may be of a left and right curtain type (5) that moves up and down.

29 is a front control panel, the details of which are shown in FIG. 3(a). 291 is a room temperature setting section consisting of a digital display section and a switch for raising and lowering the set temperature; 292;
293 is a blower switch section for stopping the operation of the front air conditioner and selecting all modes of the front blower, and 293 is a changeover switch for selecting whether to collectively control the rear air conditioner 2.3 at the front.

Reference numeral 44 denotes a rear control panel, which includes a rear seat room temperature setting section 441 and a rear blower mode selection switch 442, as shown in FIG. 3(b).

In addition, each switch in each of the above-mentioned control panels is a self-resetting type bush switch.

In addition, the blower switch section (292, 442) is stopped (O
FF), [LJ clause (AUTO), low speed (LO), high speed (
Select 4 modes: Hl). Although not described in detail, the front seat control panel 29 can be integrally configured with an operating lever or switch (6), not shown, for switching the blowout mode of the front air conditioner l.

301')j: The above sensor and control panel signals are changed and held so that they can be digitally processed, and data is sent to the computer 31 through an input circuit section including an A/D toilet converter.

The digital computer 31 is a single-chip microcomputer that performs arithmetic processing according to a predetermined control program, and is connected to a megahertz (MFTz) crystal oscillator 32. Stabilizing voltage 'ff: The voltage generated in the figure becomes operational due to the stable northern force rimO1 voltage.

The microcomputer 31 has an I-?OM which stores a control program, a C which performs arithmetic processing according to the contents of this FOM, and an R which temporarily stores each yuzu deg.
It is based on a 1-chip LSI whose main parts include a 10-circuit section that adjusts the input/output of A, M, and each Yuzu, and a clock generator that generates a standard pulse for each process. The microcomputer 31 performs calculations, judgments, and other processing on signals from various sensors, control panels, etc. using a control program, and sends command signals to each drive circuit section, which will be described next.

33, 34, and 35 are circuit units that supply power to the blower motors 4, 8, and 10 according to command signals from the computer 31. For example, they convert digital code signals output from the computer 31 into analog voltages, and change the base voltage of the power transistors. Furthermore, the rotational speed of the blower motor, which serves as a collector load, is changed steplessly. 3
6 to 39 are the refrigerant valves 1 according to the instructions from the computer 31.
This is a circuit section that opens and closes each normally closed electromagnetic valve such as 3°J5 and water valve 18 and 19. 40 is a damper drive unit 41 composed of a motor and a link mechanism for changing the opening of the air mix damper 7, or an electromagnetic valve and a diaphragm for switching between engine negative pressure and atmospheric air, and the temperature of the air blown from the air conditioner l is calculated by the computer 31. A circuit that sends a signal in response to the output of the computer 31 so that the blowing temperature becomes the same, converts the digital signal of the computer 31 into an analog voltage, compares it with the signal of the potentiometer 7a of the damper 7, and controls the drive unit 41. Reference numeral 42 denotes a circuit that controls the connection and disconnection of the η magnetic clutch 20 of the compressor 20 in accordance with a command signal.

The above is the main configuration of the present invention.Although not shown, the front air conditioner 1 includes a suction/outlet switching mechanism, etc., for example, as a manual operation mechanism, but this itself is not the main point of the present invention, and well-known technology is adopted. It is possible.

Next, the operation of the above configuration will be explained with reference to the flowcharts shown in FIGS. 4 to 6.

This FIG. 4 is a diagram showing the flow of the air conditioner control program of the present invention among the calculation processing of the microcomputer 31. Now, when this idle 1ilA1 device is activated from the front and rear control panels, the arithmetic processing f11i' of the control program is executed. That is, the arithmetic processing of the microcomputer 31 performs initial setting, etc., and the fourth
From the signal input step 100 in the figure, processing is performed sequentially at a period of several hundred milliseconds.

In the signal input step 101), signals from each sensor and the control panel (9) are sequentially input through the input circuit 30 and stored in the RAM. Note that when the collective control switch 293 is turned on here, the collective control flag is set. This flag is set in steps 102 and 105.15, which will be described later.
Used for status determination in U.

Next, in the set temperature calculation routine 100A, the preset temperature T is calculated each time the switch is pressed once, based on the rise and fall switch data input from the control springs A/43 and 44 and stored in step 100. SetFO, TsetRO are added or subtracted by a unit amount, for example, 0.5° C., and the result is stored as a front set temperature TsθtF1 and a rear set temperature T8θtR. Furthermore, when the switch is pressed, addition and subtraction are performed for each of the stored set temperatures T8etF and TsetR,
Advance the set temperature value. Furthermore, in this l chip, the set temperature value 'rsetF.

(lO) In the next step 150, it is determined whether the collective control flag is set, and if YES, the process goes to step 151;
When , the process goes to step 152.

In step 151, the front control panel is turned off.
mode, the rear control panel is also set to OFF mode, and when both front and rear are in OFF mode in step 52, step 118. Proceeding to step 11'5, each output signal is determined to stop the operation of the front A/C and rear V, and the process proceeds to step 121, a command signal output routine. If neither the front nor the rear is OFF in step 152, the process advances to step 101.

In the next step 1()1, it is determined whether the blower switch on the front control panel is in the OFF mode or in the tow mode.

If YES, proceed to step 102; if NO, proceed to step 103. In step 1()3, it is determined whether the rear control panel is in the OFF mode. If YES
If , go to step 104; if NO, go to step 10
Proceed to 5. This 7-f rough"105 is executed when the blower switches on both the front and rear control panels are in a mode other than the OFF mode, and when the front and rear air conditioners are operated at the same time.

Step 105 determines whether the front collective control switch 294 of the front spring/v29 has been pressed or not.
7. Determine whether or not to control the front control panel. If the front batch control mode is selected, the process proceeds to step 106; if NO, the process proceeds to the front required heat amount calculation subroutine of step 107.

As above, steps 101, 102, 103, 105
At , the control mode is determined, resulting in the reference numeral 100
Three loops from 0.2000.3000 to 400° are processed, and the following three control modes are executed.

Loop 1 (looo~4000) - Front air conditioner control. Only the front air conditioner 1 operates to adjust the temperature.

Roux 12 (2000-4000) - Front and rear air conditioner control. Front and rear air conditioning system 1.2.
3, turn /lli' to m degrees, and perform verse 11.

In this case, it is determined by operating the front collective control switch 294 whether the rear air conditioners 2 and 3 are placed under the subordinate control of the front air conditioner 1 or independently controlled.

Under subordinate control, in step 106, the set temperature set on the front panel, which is displayed on the rear control panel setting section 441, is changed to the rear setting section 44.
1 to determine whether the settings have been changed. If the rear setting has been changed, proceed to step 153, reset or cancel the front collective control flag, and proceed to step 07.If there is no rear setting change and f(,, in step 106, proceed to step 154, Set temperature 'T'

Proceed to 55. Here, it is determined whether or not this is the first time that the Freon batch control flag has been set. If YES, the rear fan is set to AUTO mode in step 156, and if NO, nothing is heated (13). '/Susumu to 107. In other words, when the rear blower mode S/W 442 is operated during front collective control, only the rear blower operates in the desired mode, and the rear set temperature is controlled by the front panel. This also means that operating the rear setting section during batch control will completely cancel batch control.

Under independent control, steps 106 to 107 are bussed, and the front air conditioning zone, which is assigned to the front air conditioning system 1, and the rear air conditioning zone, which is assigned to the rear air conditioning units 2 and 3, are maintained at set temperatures TsetF and TsetR, respectively. The temperature is adjusted so that

Loop 3 (30 (JO~4000) - Rear air conditioner control, only rear air conditioners 2 and 3 are operated to adjust the temperature.

The details of loops 1 to 3 will be explained below.

First, in step 107, #gffiQ, Fk required to bring the front seat to the set room temperature is calculated using equation (1).

In the next step 108, the heat tilQ,R required to bring the rear seat to the set room temperature is calculated using equation (2).

KBRKa, mF, KamR, aF, and OR are constants determined by the physical properties of the air and the body structure of the target vehicle. It will be decided based on the test results.

The next step 109 is the front required heat amount Q.

This is a subroutine that determines the command signal to be sent to each drive circuit to operate the front air conditioner l in order to obtain the following information.The details of the subroutine are shown in FIG. When the process moves to this subroutine, the process starts at step 198. In step 198, it is determined whether the front blower switch 292 is in the AUTO mode. If the result is YES, go to step 200;
If No, the blower is in manual fixed mode, so proceed to step 199 and set the air volume to the one selected with the switch.
The value of the front blower air volume command signal Wp is fixed, and the process jumps to step 201. In the AUTO mode, in step 200, the front set temperature TSetF and the front chamber 2M are set.
The air volume Wp is automatically determined based on the difference in T r F, and is calculated using a preset functional formula such that the larger the temperature difference, the larger the air volume.

Next, in step 201, the blowout temperature TaoF necessary to obtain the required heat quantity Qp with the determined air volume Wp is calculated, and in the next step 202, the air mix damper 7 necessary to obtain the required blowout lHTaOF is calculated. We are looking for the opening degree Sw. The next steps 203 to 205 are related to front water valve control, and when the damper opening degree Sw is the value Sw = 0% that blocks the heater core 6 (MAXCOOL
), the content of the front water valve command signal is determined so that the water valve 18 is fully closed and the valve 18 is opened when the water is 0% or more.

After the above processing, the subroutine is extracted and the process proceeds to the next processing, the Masseria air conditioner control subroutine (step 110). Details of this subroutine are shown in FIG. The subroutine process starts from step 300, and first it is determined whether the amounts of heat Q and R necessary for air conditioning the rear are positive or negative, and whether t, b is requesting cooling or heating. When cooling is required, the process proceeds to step 320; when heating is necessary, the process proceeds to step 321. In the cooling mode, step 320
Now, determine whether the rear blower mode is AUTO or manual. Then, the process proceeds to step 301 in AUTO mode, and to step 322 in manual mode. In step 322, the /IJIII specified by the rear control spring /L/44 is
: To fix the value of the new rear cooler blower wind command signal WRC and at the same time stop the heater blower, WRH=
Set to 0. The process then proceeds to step 302. In step 301 in the case of AUTO, the airflow command signal WRC is automatically determined based on the difference between the set room temperature 'psetR and the rear room temperature TrR, and the process proceeds to the next step 302. In this step 302, the required heat is 1lt at the determined wind jdWRc.
Calculate the outlet air temperature TaoR tray required to obtain QR.

(17) In the next steps 304 to 307, a command signal to control the rear refrigerant valve 15 is determined so as to obtain the target outlet temperature TaOR without frosting the rear evaporator 9. That is, the temperature TE of the air blown from the rear evaporator 9
When R is lower than the calculated necessary blowout air temperature TaoR, close the rear refrigerant valve 15, and in the opposite case, check whether the rear evaporator 9 frosts, that is, TER is 0°C.
It is determined whether the temperature is below 0° C., and the content of the command signal is determined so that the valve 15 is closed when the temperature is below 0° C., and the valve 15 is opened when it is serious. After this process, in step 308, a command signal is determined to close the rear water valve 19 in order to stop the supply of hot water that is not used for cooling.

Then, remove this subroutine.

On the other hand, if it is determined in step 300 that heating is necessary and steps 321 and subsequent steps are executed, steps 321, 323.3
At step 09, it is determined whether the rear blower mode is AUTO or manual, and depending on the result, the rear heater blower command signal WRH is determined using the same method as explained in steps 322 and 301. In order to stop the side blower, set WRC=0 and proceed to the next step 310. Here, calculate the blowing air temperature TaOR of # device 3, and proceed to the next step 311 ~: U1
3 to control the rear water valve 19. Tsuma J), THR
A command signal is determined to control the valve 19 to open when <'c'aon, and to close it when the opposite is true. After IJII, in order to avoid unnecessary cooling in step 314, a command value of - is determined to close the rear refrigerant valve 15, and this subroutine is skipped by +1.

After the subroutine process 11 in step 11() above, the steps in FIG. 3] 1, 11! Proceed to the clutch control routine of 1,120. Here, when the rear refrigerant valves 13 and 15 are both closed, there is no need to operate the compressor, so the clutch 20 is shut off, and the valve] 3. A command signal is determined so that the clutch 20 is turned on when either one of l5 is open. In the next step 121, the A/M damper opening determined in each process up to this point and the ON of each blower fan and valve are determined.
, OFF command signals are output to each drive circuit 33 to 40.42.

The above is how the front air conditioner 1 and the rear air conditioner 2.3 can be adjusted simultaneously and independently, and the front control panel*
7+'29, each air conditioner operates rationally to achieve the set room temperature and air volume mode instructed by the rear control panel 44.

Next, the operation when the front collective control switch 294 of the front panel 29 is activated will be explained. When the collective control signal is sent to the computer 31 by the switch 294, a determination is made in step 105 in FIG. 4, and the processing in step 106 is executed. Here, the rear room temperature setting TsetR is replaced with the front setting TsetF, and at the same time, the rear air volume control is set to AUTO mode, and the process proceeds to step 107, where the above-described processing is executed. Therefore, in the collective control mode, the rear seats are also controlled to the room temperature set by the front control spring p.

At this time, the set temperature display on the rear control panel 43 is the same value as the front, and the sibling lower mode is also set to AUTO.

When canceling collective control, UP the rear setting section 441,
Just operate the DOWN switch. However, only the rear blower was controlled as desired (1) If the blower S/W unit 442 is set to the desired mode, the settings are controlled by the front, and only the blower can be set to the desired mode.

Next, start the air conditioner on the front control panel 29 (Blower mode i, i 0 F on the rear panel)
The operation when F) is explained.

At this time, from step 101 to step 1 in FIG.
This is the case when going to 02. In step 102, it is determined whether batch control is required, and if YES, proceed to step 106.
As described above, the front panel 29 controls the front and rear island air conditioners. If it is not batch control, step 112
Moving forward, it is determined whether the front and rear seats are separated by a curtain 433. This determination is performed by the sensor 43, and when the curtain is closed, the necessary heat amount QFe is calculated in the front necessary heat flatness calculation subroutine in step 107 (the next front air conditioner control subroutine (2)). Controls the damper opening degree and each valve, and then starts the next rear air conditioner stop routine f-11.
5 is performed and the process goes to step 111. Step 11
Specifically, in step 5, a command signal is set to stop the blower blower 8°lO and close the valves 15 and 19.

If the curtains are opened in step 112, the space to be covered by the front air conditioner 10 will include the rear seats or a part of the rear seats, so the formula for calculating the required amount of heat will be changed to increase the amount of heat. do. When the curtain is finally opened, the heat amount calculation formula modified in step 113 is used to determine the required heat amount Qp, and the process proceeds to step 114. Here, the calculation formula in step 113 is basically the same as formula (1), but KsetF.

The values of constants such as Cp are set to different values in advance.

As can be seen from the above explanation, when the air conditioner is started using the front panel 29 (rear air conditioner is 0FF), it is also possible to control the rear air conditioner from the front using the collective control switch 294. Even when only the front air conditioner is operating, the air conditioning capacity is automatically controlled depending on the state of the curtains separating the front and rear (22) seats, so the room temperature of all fJil seats can be controlled to the set room temperature.

Next, a description will be given of the processing in loop 3 when only the rear air conditioner (freon) is operated and when the rear air conditioners 2 and 3 are operated on the serial panel 44. In this case, the process goes from step 103 to step 104. At steps 104, 108, and 116, Lou 1
Similar to 1, the required heat iQ and R are determined according to the state of the curtain, and in step 117, the air conditioner iF is activated to release the heat sensitivity QR.
A command signal for driving the air conditioner 72.3 is determined, and in step 118 the front air conditioner 1 is stopped, and the process moves to step 111. Step 116 heat amount a release KS
θtR.

It is the same as equation (2) except that constants such as CR are changed. 1. The concrete process of step 118 is to set a command signal to stop the front blower 40 and close the pulps 13 and 18.

Therefore, the rear air conditioner t23 is controlled by the rear spring 1V44.

Note that after the output step 121 processing, processing related to other air conditioner control such as switching between intake and blowout of the front air conditioner l (not shown) can also be executed.

The present invention can be implemented by the embodiments described below.

(1) Judgment of each control For example, in steps 203, 206, 300, 304, and 305, 311, it is natural to provide an appropriate hysteresis to prevent hunting and stabilize the control.

(2) When all blowers are automatically controlled, values such as the required blowing temperature (TaoF, TaoB) of each air conditioner may be used instead of determining each air volume based on the difference between the set room temperature and the room temperature.

(3) Refrigerant pulp 15
EPR that allows you to change the set pressure instead of controlling it by opening and closing the
etc. may also be used. Furthermore, instead of controlling the temperature of the air blown from the heating-only air conditioner by opening and closing the hot water pulp 19, it is of course possible to control the temperature by using pulp with a variable flow rate.

(4) Although a curtain was used as a partition between the front seat and the rear seat, and a curtain opening/closing detector was used as the sensor, the present invention is not limited to this. For example, when electric curtains are used, the size of the air-conditioned space may be detected based on signals from a curtain opening/closing command switch, and the partition may be not only a curtain but also a wavy door.

(5) Although the embodiment has been shown in which each of the front and rear seats has an automatic room temperature control air conditioner, the present invention has an automatic room one-item control air conditioning system only in the front seats or only in the rear seats. Of course, this also applies to vehicles.

(6) In a case where only the front seats are equipped with an air conditioner and temperature-controlled air is sent to the front and rear seats through ventilation ducts, when the ventilation ducts toward the rear seats are distributed with dampers etc. , the amount of heat supplied may be reduced.

(7) The present invention can also be applied to the case where a space volume to be air-conditioned is specified by a switch or the like without using a wind shielding means with a curtain door. Further, the switch may be a switch that detects seating of a rear seat passenger.

(25) (8) Use a monitor that indicates that front collective control is in progress, such as a lamp (such as by making the collective control switch 293 illuminated), which lights up when the collective control flag is set. , it may be possible to notify the crew.

(9) As methods for canceling collective control, we have shown a method of canceling by operating the setting device on the rear panel, and a method of canceling only blower control by operating the blower switch, but this is not limited to this, and any switch on the rear panel can be used. When you operate
It may be arranged so that all of them are canceled. Further, a release switch may be provided on the rear panel or the front panel.

Although two types of αtj rear air conditioners are used, one for cooling only and one for heating only, a single air conditioner capable of cooling and heating may be used.

As explained above, the temperature of multiple spaces can be controlled independently,
At the same time, it is possible to adjust the air conditioning according to the preferences of each passenger, and at the same time, it is possible to control multiple control springs (VF) all at once from one place as needed, so there is no need to operate each panel even when there is only one passenger ( 26) It has the excellent effect of providing comfortable air conditioning.
