0002

2. Description of the Related Art Conventionally, in an auto mode, a vehicle air conditioner adjusts the temperature or volume of air blown into a vehicle interior so that a preset interior temperature is achieved. Further, in this type of device, one provided with a thermal input operation switch is known. This includes a first operation switch that is operated when the occupant feels hot, and a second operation switch that is operated when the occupant feels cold.
When the first operating switch is operated, the set indoor temperature is forcibly lowered by a predetermined amount, and when the second operating switch is operated, the set indoor temperature is forcibly increased by a predetermined amount.

0003

[Problems to be Solved by the Invention] However, in the conventional device, the set indoor temperature is only forcefully changed by a predetermined value by operating the first and second operation switches, and it is difficult to achieve optimal air conditioning. It is insufficient from the perspective of implementation. An object of the present invention is to provide a vehicle air conditioner that can achieve optimal air conditioning using a temperature-sensitive switch.

0004

[Means for Solving the Problems] A first invention provides a vehicle air conditioner that adjusts the temperature or air volume of air blown into a vehicle interior so that the temperature inside the vehicle reaches a set interior temperature. A thermal input operation switch that is operated when the user feels cold or cold, and a temperature input operation switch that forcibly increases or decreases the set indoor temperature or airflow volume by a predetermined amount when the temperature input operation switch is operated in a steady state of air conditioning. The gist of the present invention is to provide an air conditioner for a vehicle, which is equipped with a thermal sensation processing means that does not change the set indoor temperature or the airflow volume even though the temperature input operation switch is operated in a transient air conditioning state. It is.

[0005] The second invention is a vehicle air conditioner that adjusts the temperature or air volume of air blown into a vehicle interior so that the temperature inside the vehicle reaches a set interior temperature. A thermal sensation input operation switch that is operated when the user feels the temperature, and a thermal sensation processing means that forcibly increases or decreases the temperature of the blown air or the volume of the blown air by a predetermined amount in accordance with the amount of solar radiation when the temperature input operation switch is operated. The gist is a vehicle air conditioner equipped with the following.

[0006] The third invention is a vehicle air conditioner that adjusts the temperature or air volume of air blown into the vehicle interior so that the temperature inside the vehicle reaches a set interior temperature. A temperature sensing input operation switch that is operated when the user feels the temperature, and a temperature sensing input operation switch that forcibly increases or decreases the set indoor temperature or blowout air volume by a predetermined amount when the temperature input operation switch is operated, and then gradually returns to the temperature over time. The gist of the invention is a vehicle air conditioner equipped with a sensory processing means.

[0007]

[Operation] In the first aspect of the present invention, the thermal sensation processing means forcibly increases or decreases the set indoor temperature or the blowout air volume by a predetermined amount when the thermal input operation switch is operated in a steady state of air conditioning;
In the transient air conditioning state, the set room temperature or the blowout air volume is not changed even though the thermal input operation switch is operated. Note that the transient air conditioning state refers to the state from when air conditioning is started until the vehicle interior temperature reaches the set interior temperature, and is a so-called cool-down or warm-up state. As a result, with conventional equipment, even if the thermal input operation switch is operated and the set indoor temperature or airflow volume is changed when the capacity is at its maximum in a transient air conditioning state, the change is not reflected in the air conditioning and the stationary air conditioning state is reached. However, deviations may occur in the set indoor temperature or airflow volume that would otherwise be comfortable, but this can be avoided.

In a second aspect of the invention, the thermal sensation processing means forcibly increases or decreases the temperature of the blown air or the volume of the blown air by a predetermined amount in accordance with the amount of solar radiation when the thermal sensation input operation switch is operated. As a result, thermal air conditioning is performed according to the amount of solar radiation. In a third aspect of the present invention, the thermal sensation processing means forcibly increases or decreases the set indoor temperature or the blowout air volume by a predetermined amount when the thermal input operation switch is operated, and then gradually restores the temperature over time. As a result, the occupant can respond more quickly by increasing or decreasing the set indoor temperature or the air volume by a predetermined amount, and overshoot can be prevented by gradually returning the temperature over time.

3, and outputs a command signal to the air conditioning operation display device 34 to display a predetermined temperature and air volume. Furthermore, the control microcomputer 24 has a built-in memory 24a (see FIG. 1).
A map shown in FIG. 4 is stored in a. In this map, the horizontal axis shows the difference (
Tr - Tset ), and the vertical axis shows the set temperature change width ΔT.
I am taking a set. The set temperature change width ΔTset is for forcibly changing the set temperature Tset. This map has a cold time characteristic line L1 and a hot time characteristic line L2. The cold characteristic line L1 is (T
r −Tset ) is 0℃ or higher, ΔTset is +1
℃, when (Tr - Tset) is below -10℃, ΔT
set to "0" and (Tr - Tset ) to -10
℃~0℃, ΔTset is linearly directly proportional between 0℃ and +1℃. The hot time characteristic line L2 is (Tr
-Tset ) is below 0℃, ΔTset is set to -1℃, and when (Tr -Tset ) is above +10℃, ΔTset is set to -1℃.
t is set to "0", (Tr - Tset) is 0°C to +10
At °C, ΔTset is linearly directly proportional between -1 °C and 0 °C.

Next, the operation of the vehicle air conditioner will be explained using the flowchart shown in FIG. The microcomputer 24 performs initial settings in step 100 at the start of operation, and thereafter repeats the calculation processing in steps 101 to 109 to independently control the upper and lower outlets (vent outlet 8, heat outlet 9) of the air conditioner unit 1. Furthermore, thermal signal processing is performed in response to the operation of the thermal input operation switch 38.

First, in step 101, the microcomputer 24 inputs sensor signals from the inside temperature sensor 30, outside temperature sensor 25, solar radiation sensor 31, etc., and also inputs sensor signals from the switch panel 33.
Input the switch signal from And microcomputer 24
In step 102, the temperature signal generated by the operation of the temperature input operation switch 38 is processed. That is, the difference (Tr - Tset) between the inside temperature Tr measured by the inside temperature sensor 30 and the initially set temperature Tset is calculated, and based on that value,
The set temperature change range ΔTset in the map of FIG. 4 is determined, and the set temperature is determined by adding the change range ΔTset to the set temperature Tset. At this time, for example, in the early stage of the cool-down period, if the value of (Tr - Tset ) is positively large and is 10° C. or more, even if the thermal input operation switch 38 in hot weather is operated, the air conditioning state will not be cool. Maximum state (Blower voltage is H)
i, and the air mix dampers 18 and 21 are at their maximum opening on the cooling side), so the settings are not changed. On the contrary, (Tr −
If the cold temperature input operation switch 38 is operated when Tset ) is +10° C. or higher, the set temperature changes immediately after the operation of the temperature input operation switch 38. Also, when the value of (Tr - Tset) is around 0°C,
Since the air conditioning is in a stable state (steady air conditioning state), the set temperature will be changed immediately. Also, during warm-up, (Tr − Tse
When the (Tr - Tset ) value is negatively large and about -10°C, even if the thermal input operation switch 38 is operated in cold weather, the operation is ignored, and when the (Tr - Tset ) value is around 0°C, both signals are ignored. (Cold and hot weather signals) Change the settings immediately.

Next, in step 103, the microcomputer 24 calculates the amount of heat (required air temperature TAO) required for air conditioning the vehicle interior based on the following equation (1).

[0019]

[Equation 1] TAO=Kset ・Tset −Kr ・T
r -Kam・Tam-Ks ・ST +C


...(1) However, Kset, Kr, Ka
m, Ks, and C are constants. In step 104, the microcomputer 24 calculates the total air volume VA into the vehicle interior by the blower 3 based on the TAO. Furthermore, the microcomputer 24
The ratio of the total air volume VA to the heat outlet 9 and the vent outlet 8 is calculated based on the following. That is, the ratio between the heat blown air volume VH and the vent blown air volume VV by the air volume distribution unit 5 is calculated.

Then, in step 105, the microcomputer 24 calculates the heat blowing temperature TH and the vent blowing temperature TV by adjusting the opening degrees of the air mix dampers 18 and 21. Furthermore, the microcomputer 24 inputs the vent duct temperature TVin and the heat duct temperature THin from the vent duct sensor 28 and the heat duct sensor 29 in step 106. Then, in step 107, the microcomputer 24 sets the heat and vent control target temperatures TH and TV and the actual temperature THi.
The amount of deviation of n and TVin is determined, and if the amount of deviation is outside the predetermined tolerance range, the control signal to the heat or vent unit is corrected in step 108, and the air mix is adjusted so that the temperature of each duct becomes the target blowout temperature. Damper 18
, 21 correction signals are output. Further, the microcomputer 24 performs various outputs in step 109 after the processing in step 108 and if it is within the permissible range in step 107.

[0021] By repeating this process, the air conditioning capacity (air volume, temperature) of the vent and the heat outlet are independently controlled. In this way, in this embodiment, the control microcomputer 24 (thermal sensation processing means) is in the steady air conditioning state (L in FIG. 4).
1 If (Tr - Tset ) during use is -10°C or higher, or (Tr - Tset ) during use of L2 is +
10 degrees Celsius or lower), when the thermal input operation switch 38 is operated, the set indoor temperature Tset is forcibly increased or decreased by a predetermined amount, and the transient air conditioning state (L in FIG.
1 When (Tr - Tset ) during use is -10°C or lower, or when (Tr - Tset ) during use of L2 is +10°C or higher), even though the thermal input operation switch 38 is operated. Set indoor temperature Tse
Do not allow changes in t. In other words, in the conventional device, the temperature input operation switch 38
Even if the set room temperature Tset is changed by operating the air conditioner, the outlet air temperature does not change, and there is a deviation in the comfortable Tset when the steady state of air conditioning is reached.
It was necessary to operate the thermal input operation switch 38, which was complicated. In this embodiment, accurate operation can be performed by changing the temperature correction based on the input air conditioning state without changing the set room temperature Tset in the transient air conditioning state.

(Second Embodiment) Next, a second embodiment will be explained. Hereinafter, only the points different from the first embodiment will be explained,
The rest is the same as the first embodiment, so the explanation will be omitted. A map shown in FIG. 6 is stored in the memory 24a of the control microcomputer 24. In this map, the horizontal axis is the required blowout temperature TAO
The vertical axis is the set temperature change width ΔTset. This map has a cold time characteristic line L1 and a hot time characteristic line L2. The cold characteristic line L1 is TAO
is below 40℃, set ΔTset to +1℃ and TAO to 6
ΔTset is "0" at 0℃ or higher, TAO is 40℃~6
At 0°C, ΔTset is linearly inversely proportional between +1°C and 0°C. The hot time characteristic line L2 has a TAO of 0°C.
In the following, ΔTset is set to "0", -1°C when TAO is 20°C or higher, and ΔTset when TAO is between 0°C and 20°C.
is linearly inversely proportional between 0°C and -1°C.

The microcomputer 24 then executes the routine shown in FIG. Only the portions of this routine that are different from the first embodiment will be explained. Microcomputer 24 is step 1
At step 01, signals from various sensors and switches are inputted, and at step 102, the necessary blowout temperature TAO is calculated using the above equation (1). Next, in step 103, the microcomputer 24
ΔTset is determined from the map in FIG. 6 using O. At this time, the operation of the thermal input operation switch 38 when the TAO value is large (60°C or higher) or when it is cold is ignored;
In the following, ΔTset = +1°C. In addition, when operating the thermal input operation switch 38 in hot weather, when the TAO value is small (
below 0°C) is ignored, and above 20°C ΔTset =
-1℃.

Next, in step 104, the microcomputer 24 corrects the necessary blowout temperature using ΔTset obtained in step 103 (Tset +ΔTset →Tse
t). Using the Tset, TAO is recalculated using equation (1). Thereafter, control is performed using the TAO value in the same manner as in the first embodiment. As described above, in this embodiment, the control microcomputer 24 (thermal sensation processing means) is in the steady air conditioning state (FIG.
When the TAO during L1 use is 60°C or lower, or when the TAO during L2 use is 0°C or higher), when the temperature input operation switch 38 is operated, the set indoor temperature is forcibly increased by a predetermined amount or Even though the thermal input operation switch 38 is operated in a transient air conditioning state (when TAO is 60°C or higher when L1 is used in FIG. 6 or TAO is 0°C or lower when L2 is used). Do not allow changes to the set room temperature. As a result, accurate operation can be performed by changing the temperature correction based on the air conditioning state at the time of input.

(Third Embodiment) Next, a third embodiment will be explained. Hereinafter, only the points different from the first embodiment will be explained,
The rest is the same as the first embodiment, so the explanation will be omitted. As shown in FIG. 8, the value of the blower voltage (air volume of the blower 3) is corrected based on the required blowout temperature TAO. In other words, the memory 24a of the control microcomputer 24 stores the necessary blowout temperature TAO shown in FIG.
A map for changing the blower voltage correction amount ΔV is stored. In this map, the horizontal axis is the necessary blowout temperature TAO, and the vertical axis is the blower voltage correction amount ΔV. This map has a cold time characteristic line L1 and a hot time characteristic line L2. The cold characteristic line L1 has a TAO of 60°C.
If TAO is less than 60℃, ΔV is set to “0”, and if TAO is 60℃ or higher, ΔV is
is set to +0.3 volts. The hot time characteristic line L2 is
If TAO is greater than 0°C, set ΔV to “0” and TAO to 0.
At temperatures below ℃, ΔV is set to +0.3 volts. and,
The microcomputer 24 adds correction to the blowout air volume in step 104 in FIG. 5 (V+ΔV→V).

As described above, in this embodiment, the control microcomputer 24 (thermal sensation processing means) operates in the steady air conditioning state (L1 in FIG.
TAO during use is 60℃ or higher, or TAO during use is L2

1) When the TAO during use is less than 60°C, or L2 when the TAO during use is 0°C or more), the volume of blowing air is not changed even though the thermal input operation switch 38 is operated. . As a result, accurate operation can be performed by changing the temperature correction based on the air conditioning state at the time of input.

(Fourth Embodiment) Next, a fourth embodiment will be explained. Hereinafter, only the points different from the first embodiment will be explained,
The rest is the same as the first embodiment, so the explanation will be omitted. In this embodiment, thermal signal processing is associated with the amount of solar radiation. In other words,
The memory 24a of the control microcomputer 24 stores a map for changing the amount of correction of the vent outlet temperature according to the amount of solar radiation ST shown in FIG. In this map, the horizontal axis represents the amount of solar radiation ST, and the vertical axis represents the vent outlet temperature correction amount ΔTV. This map has a cold time characteristic line L1 and a hot time characteristic line L2. The cold characteristic line L1 is ST
is 100kcal/m2h or less, set ΔTV to “0”
In addition, when ST is 300 kcal/m2h or more, ΔTV
at +5℃, ST is 100-300kcal/m2h
Here, ΔTV is linearly and directly proportional between 0°C and +5°C. In the hot weather characteristic line L2, ST is 100 kca.
Below l/m2h, set ΔTV to 0 and ST to 30
At 0kcal/m2h or more, set ΔTV to -5℃, ST
is 100 to 300kcal/m2h, ΔTV is 0
It is linearly inversely proportional between °C and -5 °C.

This correction amount ΔTV is calculated from step 10 in FIG.
A correction is added to the vent outlet temperature calculated in step 5. The rest is the same as the first embodiment. In this embodiment, the control microcomputer 24 (thermal sensation processing means) forcibly increases the temperature of the air blown from the vent side by a predetermined amount in accordance with the amount of solar radiation ST when the temperature input operation switch 38 is operated. increase or decrease As a result, thermal air conditioning is performed according to the amount of solar radiation. In this way, accurate operation can be performed by changing the temperature correction based on the air conditioning state at the time of input.

As an application of this embodiment, the vent air volume may be forcibly increased or decreased by a predetermined amount in accordance with the amount of solar radiation ST when the thermal input operation switch 38 is operated. (Fifth Embodiment) Next, a fifth embodiment will be explained. Hereinafter, only the points that are different from the first embodiment will be explained, and since the others are the same as the first embodiment, the explanation will be omitted.
