Here, the heater core 18, the mix damper 19, the outlet 23
The tuning of the heater unit composed of # 24 and mode switching dampers 21 and 22 will be described. As is well known, the heater unit is tuned so that the temperature of the air blown to the foot outlet 24 is higher than the temperature of the air blown to the vent outlet 23. In other words, except for the opening degree at which the mix damper 18 does not allow air to flow to the heater core 18 (described as cold) and the opening degree at which the total amount of air flows through the heater core 18 (described as hot), the vent outlet 23 is selected to blow air. In the vent mode, the relationship between the mix door opening and the outlet temperature is as shown in FIG. 4 (a). In the bi-level mode in which the foot outlet 24 and the vent outlet 23 are selected to blow out the air, the mix door opening is set. FIG. 4B shows the relationship between the temperature and the blowing temperature.

Outlet control routine in step S ₆ is as shown in Figure 5.

In FIG. 5, c to f indicate temperatures, respectively, c <d
<E <f, a and b indicate the output of the solar radiation sensor S, and a <b. The flag "1" is a flag indicating whether or not the selection according to the manual selection order display (1) described later is the first time. The flags "2", "3", and "4" are the manual selection order display (2). (3), it is set when the corresponding, and a flag select according the order displayed indicating whether the first time, the flag "5" is the Defuroito instruction switch 28 ₄ is pressed in (4) This is a flag. Counter CN
1 to CN4 are counters for counting the number of selections of the respective order indications "1", "2", "3", and "4".

When entering the air outlet control routine, the calculated target air temperature _XM becomes C
Degrees whether is checked (step S _12), a case where the target air outlet mode is in vent mode the automatic control state when less than C degree, manual selection order display (1) is selected in advance in the ROM manual selection order stored (1) is transferred to the fourth area of the RAM, the air outlet changes order is displayed on the graphic display unit 28 ₅ with the storage contents of the fourth area of the RAM (step S _12). That is the first column of the graphic display unit 28 ₅ B / L (bilevel)
But, in the second column, FOOT (foot), in the third column, VENT
(Vent) is caused to light up, respectively, if there is no change in other conditions for each pressing of the blow mode switch 28 ₃ B / L → FOOT
→ It is displayed that VENT and the blowing mode can be changed. In the ROM, the manual selection order (1) to the target blowing mode, the target blowing mode, and the detected solar radiation amount T _S are set in advance.
(4) is stored. This is when the target blowout mode as described above is in the vent mode when the step S ₁₂ is executed, the automatic control state has a vent mode. In this state, when it is desired to change the blow mode, the feet are cool, and the blow mode switch is set.
By the pressing of 28 ₃ it is switched to the bilevel mode, still be pressed blowing mode switch 28 ₃ again when still insufficient. At this time, even if the mode is changed to the bi-level mode, the feet are still cool, and the mode is switched to the foot mode. The selection order of the manual selection order display (1) is as follows.
₃ is pressed when the upper body is comfortable but the feet feel cold. Thus following the pressing of the blow mode switch 28 ₃ are to be switched to the bi-level mode. By switching to the bi-level mode, the air temperature blown out from the foot outlet 24 is higher than the air temperature blown out from the vent outlet 23 as described above.
This is because the feeling that the feet feel cold is eliminated. By when still insufficient in level mode is pressed blowing mode switch 28 ₃ again, is switched by the pressing the foot mode. In the automatic control state before entering the manual selection order display (1), it is not necessary to switch to the vent mode because the target blowing mode is the vent mode, and the foot mode is set next to the bi-level mode.

Calculating a target air temperature X _M in step S ₁₁ is when it is determined that the c or more degrees, followed by calculation target air temperature X _M in step S ₁₁ it is checked whether or e degree (step
S _13). Incidentally are a hysteresis of c~d degree determination temperature in step S _11. Further, there is a hysteresis in e~f degree determination temperature in step S _13.

When calculating the target air temperature X _M is determined to less than e degree in step S ₁₃ is when the target air outlet mode is the bi-level mode, the automatic control state has a bi-level mode. The output of the subsequently solar radiation sensor S to step S ₁₃ it is checked whether or less a (step
S _14). Are a hysteresis in the output of the solar radiation sensor S in step S _14. When the output of the solar radiation sensor S in step S ₁₄ is judged to be less than a is transferred to the fourth area manual selection order (2) is a RAM that is stored in advance in the ROM 4, the storage of the fourth area of the RAM outlet changed order is displayed on the graphic display unit 28 ₅ with the contents (step S _15). That FOOT The first column of the graphic display unit 28 _5, in the second column VENT is, the third column in B / L is lit, respectively, outlet if there is no change in other conditions FOOT every time mode switch 28 ₃ is pressed
→ VENT → B / L indicates that the blowing mode can be changed.

When the output of the solar radiation sensor S is determined to be greater than or equal to a in step S _14, the manual selection order stored in advance in the ROM (3) is transferred to the fourth area of the RAM, a fourth area of the RAM outlet changed order is displayed on the graphic display unit 28 ₅ with the storage contents (step S
₁₆ ). That is the first column of the graphic display unit 28 ₅ V
ENT is FOOT the second column is the third column in being lit B / L, respectively, if there is no change in other conditions VENT every pressing of the blow mode switch 28 ₃ → FOOT → B / It is shown that L and the blowing mode can be changed.

When step S ₁₄ to S ₁₆ is performed is when the target air outlet mode is the bi-level mode, the automatic control state has a bi-level mode. In this case blow mode switch 28 ₃ is being pressed (i) is the colder upper body lower blowing air temperature from are comfortable vent outlet 23 feet in a state, when the hot upper body per are (b) Solar Radiation is there. Thus when the output of the solar radiation sensor S is less than a, i.e. the priority to be switched to the foot mode when less solar radiation, then when the blowing mode switch 28 ₃ is pressed, the target air outlet mode was in the bi-level mode Therefore, the vent mode was set to the next switching order. The solar radiation sensor S
When the output is equal to or greater than a, i.e. priority to be switched to the vent mode when solar radiation is large, then the foot mode for the target blowing mode is a bi-level mode when the blowing mode switch 28 ₃ is pressed following Switching order.

When calculating the target air temperature X _M is determined to be greater than or equal to e degrees in step S _13, in the automatic control state is when the target air outlet mode is the foot mode, the manual selection order (4 previously stored in the ROM ) is transferred to the fourth area of the RAM, the air outlet changes order is displayed on the graphic display unit 28 ₅ with the storage contents of the fourth area of the RAM (step S _17). That first column in the B / L of the graphic display unit 28 _5, in the second column VENT is, the third column F
OOT and is lit, respectively, if there is no change in other conditions for each extrusion blow mode switch _{28 3 B / L → VENT →} FOOT
And that the blowing mode has been changed is displayed. This is when the target blowout mode as described above is in the foot mode when step S ₁₇ is executed, it has a foot mode in the automatic control state. When you want to change the blowing mode in this state, your feet are comfortable, but when the hot air at your feet rises to the head and the head becomes fogged, or when the sun hits and your upper body is warm, There, by the pressing of the blow mode switch 28 ₃ is switched to the bilevel mode. This eliminates the hot upper body. Also blow mode switch 28 ₃ is extruded at still insufficient even switch to the bi-level mode. In this case, the mode is switched to the vent mode. The target outlet air mode because a foot mode and the lowest switching order of the blow mode by pressing the blow mode switch 28 ₃ as foot mode.

Step S _12, S ₁₅ defrost signal switch 28 ₄ Following execution to S ₁₇ is checked whether it is pressed (Step S _18), when the defrost instruction switch 28 ₄ is determined to have been pressed, blow Mode manual indicator 28 ₇

There is cleared (step S _20). Blow-out mode is set to the defrost mode is followed by step S ₂₀ (step S
_21), defrost indicator 28 ₈ is lit (step S _22).

Defrost instruction switch 28 ₄ in step S ₁₈ is judged to be in an off state, the blow mode switch 28 _3, when off switch 28 ₂ and the automatic control mode switch 28 ₁ is off (Step S ₂₃ to S _25), Flags “1” to “5”
There is checked whether it is set (step S ₂₆ ~S
_30), the flag "1" to "5" when either of is determined to have been set step S ₁ is executed. Steps
S ₂₆ when all the to S ₃₀ flag of "1" ~ "5" is determined to have been reset, a check is made operational target air temperature X _M is less than or c degree Following step S ₃₀ It is (step S _31). When calculating the target air temperature X _M is determined to be less than c degrees, the air outlet mode is set to the vent mode following step S ₃₁ (step S _33), followed by a vent mode indicators 28 ₆₂ is lit (step _S34 ).

When calculating the target air temperature X _M is determined to be c degree or higher in step S _31, the arithmetic target air temperature X _M is checked whether less than e degree Following step S ₃₁ (step
S ₃₂ ). When calculating the target air temperature X _M is determined to be less than e degree steps subsequent to S ₃₂ air outlet mode is set to the bi-level mode (step S _35), followed by the bi-level mode display, i.e. foot mode indicator 28 ₆₁ and the vent mode indicator light 28 ₆₂ are turned on (step
_S36 ). When calculating the target air temperature X _M is determined to e degrees or more in the step S _32, the air outlet mode is set to the foot mode following step S ₃₂ (step S _37), followed by a foot mode indicators 28 ₆₁ lit (Step
S ₃₈ ). Step S ₁ is executed following steps _{S 34, S 36, S 38} .
