DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air outlet control device for a vehicle, which switches the blown state of a conditioned wind into the vehicle compartment to perform better air conditioning in the vehicle compartment.

[0002]

2. Description of the Related Art As a conventional automobile air outlet control device, there is, for example, one disclosed in Japanese Patent Laid-Open No. 58-49513. The device of this conventional example is arranged on an instrument panel or the like in a vehicle compartment, and as shown in FIG. 20, a solar radiation sensor 101 for detecting a sunshine state,
The inside air sensor 103 for detecting the temperature inside the vehicle, the louvers 107a and 107b capable of freely adjusting the blowing direction of the harmonious air from the outlet by the servo circuit 105, and the detected values from the solar radiation sensor 101 and the inside air sensor 103 are used. Microcomputer 10 for automatically controlling the blowing direction of the harmony wind based on
9.

According to this conventional example, depending on the magnitude of the amount of solar radiation and the magnitude of the temperature difference between the vehicle interior temperature and the target temperature, the direction of the conditioned wind supplied from the air outlets is the concentrated air outlet directed toward the occupant. Since it is automatically switched to the diffused blowout that diffuses into the entire passenger compartment, the occupant does not need to manually switch the blown blowout state due to changes in the amount of solar radiation and the temperature in the passenger compartment, and a comfortable blowout state can be obtained.

[0004]

However, in such a conventional vehicle air outlet control device, the change of the target temperature is directly related to the blown state of the harmonious wind, and the target temperature is lowered, for example, at the time of diffused blowing. Then, the temperature difference between the vehicle interior temperature and the target temperature becomes large, and the blowout state may be automatically switched from the diffused blowout to the concentrated blowout. When the blowout state is switched from the diffused blowout to the concentrated blowout, the wind speed of the harmonious air supplied from the air outlet increases, and the passenger may feel that the temperature of the harmonious air has dropped more than expected.

Further, although the change of the set amount of the harmony wind is not directly related to the blowout state of the harmony wind, for example, when the set air amount is increased, if another factor such as a change in the amount of solar radiation acts, The blowing direction may suddenly change regardless of the change in the set air volume. When the blowout state is switched from concentrated blowout to diffuse blowout when the set air volume is increased, the wind speed of the harmony wind supplied from the outlet does not actually increase,
Occasionally, the occupant may not be able to experience the increase in air volume, and on the contrary,
When the diffused blowout is switched to the concentrated blowout, the air volume to the occupant increases more than necessary, and the occupant may feel the increase in the air volume more than expected.

Further, if the blowing direction changes when the target temperature or the set temperature is changed, not only will the occupant feel this kind of discomfort, but also the work of searching for an appropriate target temperature and set air volume will become complicated, and these settings will be complicated. However, there is an inconvenience that it takes a lot of time.

The present invention has been made in order to solve such a conventional problem, and an object thereof is to change a switch operation when a target temperature or a set air volume is manually changed by an occupant. It is an object of the present invention to provide an air outlet control device for an automobile in which the occupant does not feel uncomfortable due to the difference between the amount and the amount of change actually experienced by the occupant.

The air conditioner 7 is provided with four air outlets 49 for supplying the occupants of the respective seats 43 and 45 with conditioned air from both left and right directions. These four air outlets 49 communicate with the vent air outlet 29 of the air conditioner body 1, and each air outlet 49 is provided with a wind direction setting device 51 that sets the wind direction of the harmony wind.

The wind direction setting device 51, as shown in FIG.
Three louvers 53 that are rotatable in the horizontal direction are provided, and the direction of the louvers 53 determines the blowing direction of the harmony wind. The louver 53 is connected to a movable plate 57 that is movable along the upper surface of the air outlet 49 via a rotatable link 55. The guide pin 59 protruding from the link 55 is
When the movable plate 57 moves by being engaged with the guide groove 61 formed in the movable plate 57, the link 55 is moved along the guide groove 61.

When all the louvers 53 face the occupant 65, the blowout state of the harmony wind becomes a concentrated blow toward the occupant 65, and when the louvers 53 at both ends face outward,
The blowout state of the harmonious wind is a diffuse blowout that diffuses throughout the vehicle interior. Further, the movable plate 57 is repeatedly reciprocated from the center to the innermost side of the vehicle compartment, so that the blowout state is a swing blowout in which concentrated blowout and diffuse blowout are alternately repeated. The concentrated wind and the diffused blow differ in the sensational wind speed given to the occupant 65 even with the harmonious wind adjusted to the same air volume.
The swing blowing gives the occupant 65 a feeling of fluctuation in the wind speed.

As shown in FIG. 1, this apparatus is provided with a room temperature setting device 67 and an air volume setting device 69 as manual setting means for making it possible to manually set the conditions of the supplied harmonious air, and each has a manual switch. It is composed of. The set temperature in the vehicle compartment and the set air volume of the harmonious air are set by these setters 67 and 69, and the operation signal thereof is a controller 71 constituted by a microcomputer or the like.
The signal is input to.

Signals are also input to the controller 71 from detection values from an outside air temperature sensor 73, a room temperature sensor 75, and a solar radiation sensor 77 as a thermal environment detecting means. The controller 71 includes the intake door 15 and the vent door 3
7 and signals to each actuator of the defroster foot switching door 41 to control their opening, and to detect values from the sensors 73, 75 and 77 and set values from the setters 67 and 69. Based on this, the temperature and the air volume of the harmonious air are obtained, and a signal is output to the blower fan motor 17 and the air mix door actuator 25 to appropriately control the rotation speed of the blower fan 19 and the opening degree of the air mix door 27.

The controller 71 also constitutes switching control means for automatically switching the outlet 49 between concentrated and diffused blowing in accordance with the detected value from the thermal environment detecting means. That is, the blowout state of the harmony wind from the blowout port 49 is automatically controlled to be switched to concentrated blowout or diffuse blowout based on the detected value and the set value which are signaled.

On the other hand, in the embodiment of the present invention, each setting device 6
When 7, 7 are manually operated, an operation signal is input to the controller 71, and accordingly, the controller 72 is operated.
A signal is appropriately output to each motor 63 of the four wind direction setting devices 51 from. As a result, the automatic switching control of each air outlet 49 is interrupted, and each air outlet 49 is fixed in a predetermined state for a predetermined time. Therefore, the outlets do not switch during the manual adjustment by the setting devices 67 and 69, and the adjustment can be performed reliably and easily, and the uncomfortable feeling during the manual adjustment due to the change in the blowout state can be prevented.

Next, referring to the flow charts shown in FIGS. 6 to 10, the control operation of the vehicle outlet control device according to the present embodiment constructed as above will be described in the case of normal automatic outlet control. And the case where the automatic switching control is interrupted when the manual switch is operated and the blowout port is fixed will be described separately.

Automatic outlet switching control This control includes steps S ₁ , S ₂ , S ₅ , S ₆ , S ₇ ,
Being processed by the practice of the _{S 8, S 9, S 10} , S 11, S 12, S 13, S 14, S 24, when the ON the unillustrated air conditioner switch, the controller 71 is activated with the air conditioner main body 1 .

First, in step S ₁ , a set of constants A to H used for subsequent process discrimination and resetting of each flag value, that is, initialization are performed.

In step S ₂ , it is judged whether or not the manual switch is turned on. Here, the manual switch is O
The case where N is performed means that the room temperature setting device 67 or the air volume setting device 69
In this control, the manual switch is not operated, so the process proceeds to step S ₅ .

In step S ₅ , the outside air temperature sensor 73, the room temperature sensor 75, and the solar radiation sensor 77 determine the outside air temperature T _A , the room temperature T _IC, and the amount of solar radiation Q _SUN , and the room temperature setting device 67 and the air flow setting device 69. The room temperature set value T _SET and the air volume set value V _FAN are read, and the process proceeds to step S ₆ .

In step S ₆ , it is determined whether the air flow rate set value V _FAN is set automatically. Here, if the air volume setting value V _FAN is automatically set, the process proceeds to step S _7, applied to the blower fan motor 17 in accordance with the difference between T _IC -T _SET the room temperature T _IC at room temperature setting value T _SET voltage is set, if not automatically set, the process proceeds to step S _8, the voltage applied to the blower fan motor 17 is set to V _fAN read in step S _5, the process proceeds to step S _9.

[0033] In step S _9, the target air temperature T _OF harmonic air supplied from the air outlet 49, as determined by _{T OF = A · T A +} B · T IC + C · T SET + D · Q SUN + E, further In step S ₁₀ , this T _OF
The opening X of the air mix door 27 is calculated by using X = F · T _OF ² + G · T _OF + H. Here, A to H are steps S ₁
Is a constant set in.

[0034] Thus, after the setting of harmony air flow rate and temperature is made, the process proceeds to step S _11, the target air temperature T
_The outlet mode is selected from the foot mode, the high level mode, and the vent mode according to _OF . here,
In the foot mode, the foot outlet 33 and the defroster outlet 31 are opened, and in the high level mode,
The vent outlet 29 and the foot outlet 33 are opened,
In the vent mode, only the vent outlet 29 is opened.

In step S ₁₂ , it is determined whether or not the outlet mode selected in step S ₁₁ is the foot mode. If it is determined that it is not the foot mode, that is, the high level mode or the vent mode, the process proceeds to step S ₁₃ . After the transition, the state of the harmonious air blown from the air outlet 49 is concentrated,
It is selected from diffusion blow and swing blow. Specifically, the target outlet temperature T _OF obtained in step S ₉ is
When the temperature is lower than 10 ° C, concentrated blowout is performed. When the temperature is 10 ° C or higher and 25 ° C or lower, swing blowout is performed, and when the temperature is higher than 25 ° C, diffusion blowout is performed. Here, the maintenance time ratio between the concentrated blowout and the diffused blowout during the swing blowout is set so that the lower the T _OF is, the larger the concentrated blowout is, and the higher the temperature is, the more the diffused blowout is increased.

[0036] When the blow state is selected, the process proceeds to step S _14, it is determined whether the manual flag is ON, this control is, since the manual flag is not ON, step S ₂₄
Move to.

In step S ₂₄ , the applied voltage set in steps S ₇ and S ₈ is applied to the blower fan motor 17, the opening X determined in step S ₁₀ is applied to the air mix door actuator 25, and also in step S 24. Vent door actuator 35 and defroster foot switching door actuator 3 according to the outlet mode selected in ₁₁
Signals are output to 9 respectively.

As a result, the harmonious air adjusted to a predetermined temperature and air volume is supplied from the air outlet, and the air blowout state is automatically switched and controlled in accordance with changes in the vehicle interior temperature and the amount of solar radiation.

Discontinuation of automatic switching control and fixing of air outlet This control is processed by carrying out steps S _{1 to} S _{32. During} the automatic switching control , either or both of the room temperature setting device 67 and the air volume setting device 69 are operated. When manually operated, in step S _2, it is determined that the manual switch is ON, the process proceeds to step S _3.

In step S ₃ , the manual switch flag is turned on, and the air volume setting value and the room temperature setting value before the manual switch is turned on are stored as V ₀ , [T _SET ] ₀ , and then the process proceeds to step S ₄ . . In step S ₄ , the integrated value ΔV of the air volume change width and the integrated value ΔT _SET of the room temperature change width are 0.
The timer t is reset and then started, and the process proceeds to step S ₅ .

[0041] In step S ₅ to S _13, the automatic switching control similar processing is performed, the process proceeds to step S _14. Here, in step S ₅ , the room temperature set value T _SET is changed when the room temperature setting device 67 is operated, and the air flow setting value V _FAN is changed when the air amount setting device 69 is operated.

[0042] In step S _14, the manual flag whether ON is determined, in this control, the manual flag Since ON, the process proceeds to step S _15.

In step S ₁₅ , the time t ₀ for maintaining the blowout state by the vent blowout is calculated based on the flow shown in FIG.

In this calculation process, first, step S ₂₆
Then, it is judged whether the operated manual switch belongs to the air volume setting device 69 or the room temperature setting device 67, and the air volume setting device 6
In the case of 9, the process proceeds to step S _27, and in the case of the room temperature setting device 67, the process proceeds to step S ₃₀ .

In step S ₂₇ , the integrated value Δ of the air volume change width
V is obtained by ΔV = ΔV ₀ + | V ₀ −V _FAN |, and in step S ₂₈ , the maintenance time t ₀ is longer as ΔV is larger, depending on the magnitude of this ΔV.
The smaller it is, the shorter it is. For example, it is set within 10 to 20 seconds.

Here, when the manual switch is turned on, ΔV ₀ is reset to 0 in step S ₄ , and V ₀ is stored with the air volume set value before the manual switch was turned on in step S ₃ . Since the air flow setting value after the manual switch is turned on is read in V _FAN in step S ₅ ,
ΔV is the amount of change in the air volume before and after the manual switch is turned on. As a result, the maintenance time t ₀ becomes longer as the air volume before and after the manual switch is turned on is greatly changed.

When the manual switch is repeatedly operated, t ₀ is newly set every time the manual switch is operated.
Even in this case, the blowout state is maintained fixed for a long time.

[0048] After obtaining the maintaining time t _0, in step S _29, V _FAN to V ₀ is also the [Delta] V ₀ [Delta] V are stored. As a result, the maintenance time t ₀ does not change unless the manual switch is operated.

On the other hand, in step S ₂₉ when the room temperature setting device 67 is operated, the integrated value ΔT _SET of the room temperature change width is calculated by ΔT _SET = [ΔT _SET ] ₀ + | [T _SET ] ₀ −T _SET | sought, in step S _31, depending on the size of the [Delta] t _sET, maintaining time t ₀ is, the higher [Delta] t _sET is large long, smaller short, is set, for example, between 5 to 15 seconds.

Here, when the manual switch is turned on, [ΔT _SET ] ₀ is reset to 0, and [T _SET ] ₀
The room temperature set value before the manual switch is turned on is stored in
Further, since the room temperature set value after ON of the manual switch to T _SET is loaded, [Delta] T _SET becomes a set temperature change width before and after ON of the manual switch, the manual switch O
The longer the set temperature around N is changed, the longer the maintenance time t ₀ is. Similarly, when the manual switch is repeatedly operated, the blowout state is maintained for a long time.

[0051] After obtaining the maintaining time t _0, in step _{S 32, [T SET] 0} T SET for, but also the [ΔT _{SET] 0} ΔT _SET is stored. As a result, the maintenance time t ₀ does not change unless the manual switch is operated.

[0052] With such holding time of the blow state by vent is calculated, the operation proceeds to Step S _16, blowout state selected in step S ₁₃ it is determined whether the swing blowing, if not the swing blowing , that is, when the intensive blowing or diffusion blowing, the process proceeds to step S _17,
The blowing state at that time is maintained.

Meanwhile, if the blowing state of swing blowing, the process proceeds to step S _18, the manual switch is operated, or not those or room temperature setting device 67 of the air volume setting device 69 is determined, the air volume setter In the case of 69, the process proceeds to step S _19, and in the case of the room temperature setting device 67, the process proceeds to step S ₂₂ .

[0054] In step S _19, it is determined whether a reduction or airflow change direction is increased, in the case of air flow increases the operation proceeds to Step S _20, blowing state is fixed maintained intensive blowing, also, air volume in the case of decreases in proceeds to step S _21,
The blowout state is fixed and maintained at the diffusion blowout.

On the other hand, in step S ₂₂ when the room temperature setting device 67 is operated, whether it is rising or climate change direction is lowered is determined in the case of falling, the process proceeds to step S _20, the blow-out state There are fixed maintained intensive blowing, also, in the case of rise proceeds to step S _21, blowout state is fixed maintained diffusion blowing.

When the blowout state is maintained fixed in steps S ₁₇ , S ₂₀ and S ₂₁ , the process proceeds to step S ₂₃ and step S ₄
In Start by timer t has reached or the maintenance time t ₀ obtained in step S ₁₅ it is determined, if not reached, the process proceeds to step S _24, also in the case has been reached, the step S ₂₅ Move to.

In step S ₂₄ , a signal is output to each motor and actuator. In addition the step S _25, the manual switch flag is OFF, the Thus, the manual switch flag is ON judged not in step S _14,
After that, the normal automatic outlet switching control is resumed.

[0058] Incidentally, even if the air outlet mode is determined to foot mode in step S _12, since the vent outlet 29 is closed, it remains fixed for blowing state is not performed.

As described above, according to the present embodiment, when the manual switch is operated when the blowout state of the vent blowout is the concentrated blowout or the diffused blowout, the blowout state at that time is changed by the manual switch by a wide range. Is maintained for a fixed time only, and when the manual switch is operated during swing blowing, concentrated blowing occurs when the air volume increases or the temperature drops.
When the air volume decreases or the temperature rises, it is fixed and maintained in the diffusion blowout respectively. For example, as shown in FIG. 11, when the manual switch of the air volume setting device 69 is operated and the air volume is increased when the blowout state is swing airflow, t after the manual switch is operated.
_{During 0} seconds, the blowout state is fixed to the concentrated blowout, and then the swing blowout is resumed.

Thus, when the occupant operates the manual switch, it is possible to prevent the occupant from feeling uncomfortable due to a change in the vent blowing condition. In addition, even if the amount of change in air volume or temperature is large, the occupant can experience the air volume and temperature after the change because the maintenance time of the blowout state increases depending on the amount of change, and manual operation is possible. This makes it easy to set the air volume or temperature.

Next, FIG. 12 shows the second embodiment of the present invention.
~ It demonstrates based on the flowchart shown in FIG.

The automatic outlet switching control in this embodiment is performed in steps S ₃₃ , S ₃₄ , S ₃₇ , S ₃₈ , S ₃₉ ,
Is processed by the practice of _{S 40, S 41, S 42} , S 43, S 44, S 45, S 46, S 54, since they are at the air outlet automatic switching control similar to the processing in the first embodiment, A description of each step will be omitted, and a case of interrupting the automatic switching control and fixing the outlet will be described below.

Similar to the first embodiment, when either or both of the room temperature setting device 67 and the air flow setting device 69 are manually operated during the automatic switching control, it is determined in step _S34 that the manual switch is turned on. , And _proceeds to step S35.

[0064] In step S _35, the manual switch flag is turned ON, the previous air volume set value ON of the manual switch is V ₀
After being stored as, the process proceeds to step S _36, the value of the integrated value ΔV of air volume change width is reset to 0, the timer t is started after a reset, the process proceeds to step S _37.

[0065] At step S ₃₇ to S _45, the automatic switching control similar processing is performed, the process proceeds to step S _46, the manual flag is determined whether ON, this control is a manual flag Since ON, step _Go to S47.

In step S ₄₇ , the time t ₀ for maintaining the blowout state due to the vent blowout is calculated based on the flow shown in FIG.

In this calculation process, first, step S ₅₆
Then, the integrated value ΔV of the air volume change width is obtained by ΔV = ΔV ₀ + | V ₀ −V _FAN |, and in step S ₅₇ , the maintenance time t ₀ is large in ΔV in accordance with the magnitude of this ΔV. So long,
The smaller it is, the shorter it is. For example, it is set within 10 to 20 seconds. As a result, as in the first embodiment, the maintenance time t ₀ becomes longer as the air volume changes largely before and after the manual switch is turned on, and also becomes longer when the manual switch is repeatedly operated.

Further, in this embodiment, even when the manual switch of the room temperature setting device 67 as well as the air amount setting device 69 is operated, the maintenance time t ₀ is set only by the fluctuation range of the air amount. For example, in step _S37 , the air volume setting value V _FAN
Is automatically set, and the room temperature set value T _SET is changed by operating the manual switch of the room temperature setting device 67, the maintenance time t _{0 at} this time is changed by the air flow set value V _FAN obtained in step S _39. For example, it is set according to the fluctuation range of the air volume setting value V _FAN , and if the air volume setting value V _FAN is unchanged, it is set to the shortest 10 seconds.

[0069] After the hold time t ₀ is After determining, in step S _58, V _FAN to V ₀ is also the [Delta] V ₀ [Delta] V are stored.

[0070] When the maintaining time of the blow state by this way vent is calculated, the operation proceeds to Step S _48, blowout state selected in step S ₄₅ Do is determined whether the swing blowing, if not the swing blowing _Shifts to step S _49, and the blowout state at that time is maintained.

[0071] On the other hand, if the blowing state of swing blowing, the process proceeds to step S _50, whether a reduction or airflow change direction is increased is determined, in the case of air volume increase or no change, step S ₅₁ transition to the outlet state is fixed maintained intensive blowing, in the case of reduction, which remain fixed to the diffusion blowing operation proceeds to step S _52.

When the blowout state is fixedly maintained in steps S ₄₁ , S ₅₁ and S ₅₂ , the process proceeds to step S ₅₃ and step S _36.
In Start by timer t has reached or the maintenance time t ₀ obtained in step S ₄₇ it is determined, if not reached, the process proceeds to step S _54, also in the case has been reached, the step S ₅₅ Move to. In step _S54 , a signal is output to each motor and actuator. Further, in step _S55 , the manual switch flag is turned off, and thereafter the normal automatic outlet switching control is resumed.

As described above, according to the present embodiment, the setting change by the manual operation can be accurately and easily performed similarly to the first embodiment, and the air volume can be changed regardless of the type of the operated manual switch. The duration of the blowout state is set only by the fluctuation range of the air flow rate, and the blowout state that is fixed and maintained during the swing blowout is determined only by the direction of change in the air flow rate. The vehicle is fixedly maintained, and the occupant's discomfort during manual switch operation can be further alleviated.

In this embodiment, when the blowing state is the swing blowing, when the air volume does not change even if the manual switch is operated, the concentrated blowing is kept fixed. May be maintained.

Next, FIG. 17 shows the third embodiment of the present invention.
It will be described based on the flowchart shown in FIG.

[0076] This example fixed maintenance of the air state during the swing blowing in the first embodiment, the present invention is made in blowing direction during operation of the manual switch, blowing state swing blowing at step S ₁₆ in FIG. 8 If it is determined, the process _proceeds to step S ₅₉ .

In step S ₅₉ , the louver 53 at that time is
At the position, the drive motor 63 of the wind direction setting device 51 is stopped, and the blowing direction is maintained fixed. In step S _60, the timer t is which is started in step S _4, step S ₁₅

[0088] In step S _75, a determination is made as whether the delivery direction is any direction at that time, if the intensive blowing of most concentrated, fixed maintained intensive blowing operation proceeds to step S _76, the most diffused diffusion If it is a blowout, the process proceeds to step S ₇₇ and is fixedly maintained to the diffusion blowout, and if it is the other position, that is, if it is an intermediate position between the concentrated blowout and the diffusion blowout, the process proceeds to step S ₇₈ .

[0089] In step S _78, the air volume variation direction is determined, fixed maintained intensive blowing operation proceeds to step S ₇₆ if the increase or no change, the transition to diffuse blowout to step S ₇₇ if the reduction Maintained fixed.

[0090] When blowing state in step S _76, S ₇₇ is fixed maintained, the process proceeds to step S _79, whether the timer t has reached t ₀ is determined, if not reached, step S
_In step S81, signals are output to the respective motors and actuators, and if the signals have been reached, step _S81 is entered in which the manual switch flag is turned off, and then the normal automatic blowout port switching control is resumed.

As described above, according to the present embodiment, similar to the second embodiment, the uncomfortable feeling at the time of operating the switch is alleviated in response to the change in the air volume, and the setting change by the manual operation becomes accurate and easy. Especially when a manual operation is performed during swing blowing, if the blowing direction at the time of operation is concentrated blowing or diffusion blowing, it is fixedly maintained in the blowing direction at the same time as the manual operation, and the concentration blowing direction and the diffusion blowing direction are In the middle direction, the blowing direction is fixed and maintained according to the direction of air volume change by manual switch operation.Therefore, the blowing direction is kept fixed without impairing the feeling of swing air volume change due to swing blow during manual operation. Will be even less.
