[0002]

2. Description of the Related Art In recent automobiles, for example, as described in JP-A-3-224818, a radiant panel (thermoelectric conversion device) provided with an air conditioning unit (air conditioner) provided on the inner surface of a door, for example. Some of them are assisted by Thereby, there is an advantage that efficient cooling and heating can be performed, and energy saving and improvement in fuel efficiency can be realized.

[0003]

By the way, it is often the case that a single driver rides a vehicle without putting a person in the passenger seat. Even in such a case, in the above-described conventional configuration, the temperature of the left and right radiation panels is adjusted in the same manner, but the distance between the driver and the left and right radiation panels is far left (passenger seat side) and far right. (Driver's seat side), so in the case of single driver only driver, if the left and right radiation panels are adjusted to the same temperature,
The amount of heat received by the driver is smaller on the left side than on the right side, and the driver may feel that the left side is cold during heating. In other words, if there is also a passenger in the passenger seat,
During heating, the body temperature of the passenger in the front passenger seat becomes a heat source of about 36 ° C, so the amount of heat received by the driver is balanced on the left and right, but when no passenger is on the front passenger seat, the passenger seat side Since the heat source (person) at about 36 ° C. is eliminated, the driver feels that the passenger side is cold. Such a situation is the same also at the time of cooling.

The present invention has been made in view of such circumstances, and has as its object to balance the amount of heat received by an occupant on the left and right even when no person is sitting on a side seat, and to radiate radiation. It is an object of the present invention to provide a vehicle air conditioner capable of realizing comfortable energy-saving air conditioning using a panel.

Occupant detection means for detecting whether the air conditioning capability of the radiant panel on the side where no person is sitting when the seat where no person is sitting is detected by the occupant detection means. A correction means for correcting the air conditioning capacity to be higher than the air conditioning capacity is provided.

[0006]

According to the above arrangement, the occupant detection means detects whether or not a person is sitting on a seat at a position receiving radiant heat from the radiant panel. If an unoccupied seat is detected, a correction is made. By means, the air conditioning capacity of the radiation panel on the side where no person is sitting is corrected to be higher than the air conditioning capacity of the radiation panel on the side where the person is sitting. This allows
The temperature of the radiant panel on the side where no person is sitting is adjusted to be higher during heating (or lower during cooling) than the surface temperature of the radiant panel where the person is sitting, and the occupant receives from the radiant panel. Balance the amount of heat between left and right.

11 light-emitting elements 56a are arranged in a horizontal row, and the setting state of the temperature level S is displayed by the position of the light-emitting element 56a to be turned on.

On the other hand, as shown in FIGS. 2 and 3, the inner panels of the left and right doors 60, 61 on the front seat side are formed as radiating panels 62, 63 for radiating radiant heat, respectively. A heating / cooling source 64 composed of a conversion device or the like is provided. Each radiation panel 62,
The radiating surfaces (surfaces) 63 have radiating surface temperatures Tw1 ',
Radiation surface temperature sensors 41 and 42 for detecting Tw2 'are provided. Further, the passenger seat 65 has an occupant sensor 66 as occupant detecting means for detecting whether or not a person is sitting on the seat.
Is provided. The occupant sensor 66 is constituted by, for example, a pressure switch. On the other hand, the ECU 37 determines whether or not a person is sitting in the driver's seat 67 based on an on / off signal of an ignition switch (hereinafter referred to as “IG switch”) 68 (see FIG. 6).
This takes into account the situation in which the driver is sitting in the driver's seat 67 when the ignition switch 68 is turned on.

The aforementioned ECU 37 is mainly composed of a microcomputer, and has a built-in ROM (not shown).
Stores a control program shown in FIG. The ECU 37 executes the control program shown in FIG. 1, and when the occupant sensor 66 detects that no person is sitting on the passenger seat 65, the radiant panel on the passenger seat 65 side (the side where no person is sitting) is provided. 62 air conditioning capacity
It functions as correction means for correcting the radiation panel 63 on the side (the side on which a person is sitting) to be higher than the air conditioning capacity.

Hereinafter, the control contents of the ECU 37 will be described with reference to the flowchart of FIG. First, in step 101, while reading the temperature level S set by the temperature level setting switch 55, the inside air temperature sensor 44
And the outside air temperature (outside air) detected by the outside air temperature sensor 45.
And the solar radiation amount T detected by the solar radiation sensor 46.
s, the output signal of the occupant sensor 66, the vehicle speed signal V from the vehicle speed sensor 57, and the radiation surface temperatures Tw of the left and right radiation panels 62, 63 detected by the radiation surface temperature sensors 41, 42.
1 'and Tw2' are read.

Next, at step 102, the radiation panel 6
The vehicle interior set temperature Tset 'in the off state of 2, 63 is obtained from the relationship shown in FIG. For example, in FIG.
When it is 0, Tset '= T0, and the thermal sensation level S =
+2, Tset '= T + 2, and the thermal sensation level S
When = -2, Tset '= T-2.

Thereafter, in step 103, the radiation panel 6
The target outlet temperature Tao 'of the air conditioning unit 21 when the air conditioner 2 and 63 are off is calculated by the following equation (1). Tao '= Kset Tset' -Kr Tr-Kam Tam-Ks Ts-C (1) where Tr is the inside air temperature detected by the inside air temperature sensor 38, and Tam is detected by the outside air temperature sensor 39. The outside air temperature, Ts, is the amount of solar radiation detected by the solar radiation sensor 40, Kse
t, Kr, Kam, and Ks are coefficients, and C is a constant.

Next, in step 104, the radiation panel 6
The required heat quantity Qao for turning the inside air temperature Tr in the vehicle interior to the vehicle interior set temperature Tset 'when the vehicle is turned off at the time of 2, 63 is shown in the following (2).
It is calculated by the formula. Qao = Cp · γ · Va · (Tao′−Tr) (2) where Cp is the specific heat of air at a constant pressure, γ is the specific weight of air, and V
a is the blowing air volume. Thereafter, in step 105, it is determined whether or not the required heat quantity Qao ≧ 0. If “YES”, that is, if Qao ≧ 0, the heating mode is set and the process proceeds to step 106.

In step 106, the target radiation surface temperature Twi (the surface temperature of the radiation panels 62 and 63) is determined so as to save the most energy (the energy saving degree ε is maximized). Here, the energy saving degree ε is obtained by the following equation (3). .epsilon. = (Qr-Qp) / Qao (3) where Qr is the saving of the air conditioning unit 21 obtained from the decrease .DELTA.T (see FIG. 10) of the vehicle interior set temperature due to the heating effect of the radiation panels 62 and 63. Energy, Qp
Is the input power of the radiation panels 62 and 63 required to bring the surface temperatures of the radiation panels 62 and 63 to the target radiation surface temperature Twi. Qao is the amount of heat required to bring the inside air temperature Tr in the vehicle compartment to the vehicle compartment set temperature Tset 'when the radiation panels 62 and 63 are turned off, and is obtained by the above-described equation (2).

The energy saving amount Qr of the air conditioning unit 21 is affected by the outside air temperature Tam and the vehicle speed V, and the input power Qp of the radiation panels 62 and 63 is affected by the inside air temperature Tr, the outside air temperature Tam and the vehicle speed V. Since the required heat quantity Qao is affected by the outside air temperature Tam and the vehicle speed V, the energy saving degree ε varies depending on the vehicle structure, but as shown in FIG. 8 as an example. FIG. 8 shows that the outside air temperature Tam = −
The energy saving ε at 10 ° C. is calculated as follows: vehicle speed V = 0 km /
h, 20 km / h, 40 km / h, 60 km / h, 80
km / h is indicated by a solid line, and the input electric energy Qp of the radiant panels 62 and 63 is represented by the following equation: outside air temperature Tam = −10 ° C., −8 ° C.
-5 ° C, -3 ° C, and 0 ° C are indicated by alternate long and short dash lines.
As described above, the target radiation surface temperature Twi is determined to be a temperature at which the energy saving degree ε is maximized.
At 80 km / h, Twi = T1 is determined and 60 km
When m / h, Twi = T2 is determined and 40 km / h
When Twi = T3, Twi = T4 is determined at 20 km / h, and Twi is determined at 0 km / h.
= T5.

After the target radiant surface temperature Twi is determined as described above, in step 107, in accordance with the outside air temperature Tam and the vehicle speed V, it is necessary to achieve the target radiant surface temperature Twi from the characteristic data of FIG. The input power Qp of the radiant panels 62 and 63 is determined.

On the other hand, if "NO" in the step 105, the cooling mode is set, and the process shifts to a step 108, where the target radiation surface temperature Twi is set so that the energy saving degree ε becomes the maximum as in the above-mentioned heating. Decision (step 108)
The input power Qp of the radiation panels 62 and 63 required to achieve the target radiation surface temperature Twi is obtained (step 10).
9).

As described above, for both heating and cooling, the target radiant surface temperature Twi and the input power Qp of the radiant panels 62 and 63 are set.
Is determined, the process proceeds to step 110, where the occupant sensor 6
From the output signal of No. 6, it is determined whether or not the occupant is sitting beside the driver. Note that since it is impossible to drive a car without a person sitting in the driver's seat 67, when the ignition switch 68 is turned on, the driver cannot drive in the driver's seat 6.
7 is assumed to be sitting. Step 110 above
If the answer is "YES", that is, if the occupant is sitting beside the driver, the left and right radiation panels 6 receive the heat from the other party's body temperature and balance the amount of heat received by the occupants.
There is no need to correct the target radiation surface temperatures Tw1 and Tw2 of 2,63. Therefore, in this case, at step 111, Tw1
= Tw2 (= Twi).

On the other hand, "NO" in step 110,
That is, if the occupant is not sitting beside the driver, for example, the driver feels that the left side (passenger seat 65 side) is cold during heating, so the process proceeds to step 112 and the side where no person is sitting is placed. The surface temperature of the radiant panel 62 on the side of the passenger seat 65 (the side of the driver's seat 67) is determined by measuring the surface temperature of the radiant panel 62 on the side of the seat (the side of the driver's seat 67).
The temperature is corrected by the following equation (4) so as to be higher than the surface temperature of No. 3.

Tw1 = Ts + ψ2 / 1 · (Tw2−Ts) (4) Tw1; target radiant surface temperature of the radiant panel 62 on the passenger seat 65 side Tw2; target radiant surface temperature of the radiant panel 63 on the driver seat 67 side Ts: Body surface temperature of the occupant ψ1; Angular relationship between the radiant panel 62 on the passenger seat 65 side and the driver (view factor) ψ2; Angular relationship between the radiant panel 63 on the driver seat 67 side and the driver ( In general, the difference in the amount of radiant heat received by the occupant from the left and right is determined by the view factors ψ1 and ψ2.
By correcting the target radiation surface temperature Tw1 in accordance with the ratio of 2, the amount of heat received by the occupant is balanced on the left and right.

For reference, the above equation (4) is derived as follows. Generally, the total amount of radiant heat QRT received by each occupant is obtained by the following equation.

[0025]

(Equation 1) Qi: amount of radiant heat from radiant surface i (radiant panels 62, 63) αri; radiant heat transfer coefficient of radiant surface i Twi; surface temperature of radiant surface i (target radiant surface temperature) Si: area of radiant surface i ψi: radiant surface In this case, the radiant heat transfer coefficient αri of the left and right radiation surfaces i (radiation panels 62 and 63), the body surface temperature Ts of the occupant, and the area Si of the left and right radiation surfaces i are: Since the left and right can be considered equal,
Radiant heat quantity Q1, Q given to the occupant from the left and right radiation surfaces i
The relationship between the left and right target radiation surface temperatures Tw1 and Tw2 that makes 2 equal is derived by solving the following equations (7), (8), and (9), and the above-described equation (4) is obtained.

Αr1 · ψ1 (Ts−Tw1) S1 = αr2 · ψ2 (Ts−Tw2) S2 (7) αr1 = αr2 (8) S1 = S2 (9) Therefore, the occupant sits next to the driver. If not, the target radiation surface temperature Tw1 on the passenger seat 65 side is corrected to be higher than the target radiation surface temperature Tw2 on the driver seat 67 side during heating according to the above equation (4), and Tw1 is decreased to Tw2 during cooling. After the correction is made to be lower than the above, the process proceeds to step 113, and the target outlet temperature Tao of the air conditioning unit 21 when the radiation panels 62 and 63 are turned on is calculated by the following equation (10). Tao = Kset · Tset−Kr · Tr−Kam · Tam−Ks · Ts−C (10) where Tset is the vehicle interior set temperature when the radiant panels 62 and 63 are turned on. Desired. For example, when the thermal sensation level S = 0 is set, FIG.
, The temperature Tso at the intersection of the straight line of S = 0 and the target radiation surface temperature Twi obtained in step 106 or 108 becomes the vehicle interior set temperature Tset, and similarly, when the thermal sensation level S = + 2, Tset = Ts + 2. When the warm feeling level S = -2, Tset = Ts-2.

After calculating the target outlet temperature Tao by the above equation (10), the routine proceeds to step 114, where the air conditioning unit 2
1 is controlled so that the blown air temperature becomes the target blown temperature Tao, and the surface temperatures of the left and right radiating panels 62 and 63 are controlled so as to become the target radiating surface temperatures Tw1 and Tw2, respectively. Thereafter, by returning to step 101 and repeating the above-described processing, the air-conditioning effect of the radiant panels 62 and 63 is appropriately corrected depending on the presence or absence of the occupant in the passenger seat 65, and the sensation felt by the occupant is set by the sensation level setting switch 55. The air conditioning unit 21 and the radiant panel 8 are set so that the set warm feeling level S and the energy consumption are minimized.
1 is comprehensively controlled.

According to the first embodiment described above, when the occupant is not sitting beside the driver, the target radiation surface temperature Tw1 on the passenger seat 65 side is set, and the target radiation surface temperature on the driver seat 67 side is set during heating. Since the correction is made to be higher than the temperature Tw2 (and lower than Tw2 during cooling), the amount of heat received by the occupant can always be balanced on the left and right irrespective of the presence or absence of the occupant in the passenger seat 65, and the radiation panel It is possible to realize comfortable energy-saving air-conditioning using the air conditioner.

In addition, the target radiant surface temperature Twi (the surface temperature of the radiant panels 62 and 63) is determined so as to maximize the energy saving degree ε defined by the equation (3). And the greatest energy saving and fuel efficiency improvement can be realized. However, in the present invention, the energy saving degree ε
In FIG. 8, the target radiation surface temperature Twi may be set to the most comfortable temperature for the occupant within a range where the energy saving degree ε> 0 in FIG. If the energy saving degree ε> 0, an energy saving effect can be obtained.

If the target radiant surface temperature Twi is set too high, the occupant's face will be flared and the driver will feel uncomfortable. Therefore, the upper limit of the target radiant surface temperature Twi is set to, for example, 40 to 50 ° C. The target radiation surface temperature Twi may be set within the range not more than the upper limit temperature.

In the first embodiment, the radiation panels 62, 6
Although a thermoelectric conversion device is used as the heat generation / cooling source 64 of the third embodiment, a part of the wind blown out of the air conditioning unit 21 is transmitted to the door 6.
Alternatively, it may be guided into 0,61.

In the first embodiment, the radiation panels 62,
63 was also turned on during cooling, but the radiation panel 6
2, 63 may be turned on only during heating and turned off during cooling. This is embodied in the second embodiment of the present invention shown in FIG. In the second embodiment,
"NO" in the step 105, that is, the cooling mode (Qao <
If it is determined as 0), the process proceeds to step 115, where the radiation panels 62 and 63 are turned off. After this, the previous step 1
The target outlet temperature Tao ′ when the radiation panels 62 and 63 are off determined in 03 is set to the actual target outlet temperature Tao (step 116), the air conditioning unit 21 is controlled (step 117), and thereafter, the process returns to step 101. , The same processing as in the first embodiment is repeated.

In the second embodiment, the radiation panel 6
2 and 63 are not used during cooling, so that the radiation panels 62 and 63 are not used.
A sheet heater, a heat pipe,
A hot water pipe or the like may be provided.

In the first and second embodiments described above, the inner panels of the left and right doors 60 and 61 on the front seat side are radiated by the radiation panel 6.
However, the inner panels of the left and right doors on the rear seat side may be radiation panels. In this case, occupant sensors (occupant detection means) are provided on the left and right sides of the rear seat, respectively, and the surface temperature of the radiation panel (radiation surface temperature) is determined according to the presence or absence of the occupant in the rear seat.
Should be corrected. Further, a transparent heater may be joined to the window glass of the door to use the window glass as a radiation panel. Further, the ceiling surface or the windshield of the passenger compartment may be used as a radiation panel. In this case, the radiation surface temperature may be corrected by dividing the ceiling surface or the windshield of the windshield into right and left. However, when the ceiling surface of the passenger compartment or the window glass of the door is a radiant panel, the position of the radiant panel is close to the face of the occupant.
It is preferable to set the temperature at 0 ° C. and set the target radiation surface temperature within a range of 30 ° C. or less. For reference, FIG. 12 shows the relationship between various radiation surface positions and the vehicle interior set temperature Tset.

In the first and second embodiments, the occupant sets the temperature sensation level S by using the temperature sensation level setting switch 55. Alternatively, the occupant may set the vehicle interior set temperature T.
The set may be manually set by a temperature setting switch. In the first and second embodiments, when the occupant is not sitting beside the driver, the target radiation surface temperatures Tw1 and Tw2 are automatically corrected by the ECU 37 using the equation (4). A switch for adjusting the correction amount is provided so that the occupant can change the correction amount as desired. The target radiation surface temperatures Tw1 and T2 are adjusted by the correction amount set by the switch.
w2 may be corrected.

In the above embodiment, the temperature control of the radiant panels 62 and 63 and the control of the blowing air from the air conditioning unit 21 are automatically controlled in association with each other in accordance with the setting value of the temperature sensation level setting switch 55. However, each of them may be controlled independently for the purpose of adjusting the temperature according to the occupant's temperature feeling.

For example, while the AUTO switch 49 is turned on, the radiation panel and the blowing air are controlled in association with each other. Then, when the AUTO switch 49 is turned off, the temperatures of the radiant panels 62 and 63 are set to a constant temperature (the temperature immediately before the AUTO switch 49 is turned off), and the blowing air control is determined by the setting value of the temperature level setting switch 55. Control is performed at the target outlet temperature. Then, set the IG switch 68 to OF
F, when the IG switch 68 is turned on again, the radiant panels 62 and 63 and the blown air are controlled in association with each other.
By doing so, if the filling does not match the user's preference when the radiation panels 62 and 63 are controlled in association with the blowing wind, the AUTO switch 49 is turned off and the warming level setting switch 55 is operated. Air conditioning is performed according to the user's feeling.

The present invention is not limited to the above embodiments. For example, a switch for detecting wearing of a seat belt may be used as an occupant detecting means, instead of an occupant sensor such as a pressure switch. It goes without saying that various changes can be made without departing from the gist, such as by appropriately changing the configuration of the air conditioning unit 21.

[0039]

As is apparent from the above description, according to the present invention, when a seat where no person is sitting is detected,
Since the air conditioning capacity of the radiation panel on the side where no person is sitting is corrected to be higher than the air conditioning capacity of the radiation panel on the side where the person is sitting, regardless of whether other occupants are sitting sideways, Therefore, the amount of heat received by the occupant can be balanced on the left and right, and comfortable energy-saving air conditioning using the radiation panel can be realized.
