The present invention relates to a method for intensive control of heating and cooling by a user position input, wherein a controller controls a door actuator according to a user position input, so that cold air or hot air passing through an air conditioner or a heater device is concentrated and discharged to each input position selected by a user. The present invention relates to a centralized control method for heating and cooling by inputting a user's location so that the vehicle air conditioning can be concentrated to a specific location of an indoor space by selecting a user location.

In general, the vehicle is equipped with a cooling / heating system, that is, an air conditioning system for controlling the temperature of the room.

In such a vehicle air conditioning system, air forcibly blown by a blower is cooled by passing through an air conditioner for cooling or heating in a room, or cooled by passing through a heater and then heated and then supplied into the cabin.

At this time, the driver or the passenger selects the cold or hot air by operating the cold / hot air selection switch, and when the cold or hot air is selected, the cold or hot air switching door is opened and closed to selectively open and close the cold or hot air passage, The air blown by the blower is supplied after being cooled or heated while selectively passing through the cold air passage and the hot air passage.

On the other hand, in recent years, according to the trend of high-end automobiles, high-techization is being promoted to create a more comfortable space for indoor air conditioning, and one of them is a FATC (Full Automatic Temperrature Control) system.

This FATC system automatically controls each unit for cooling, heating, ventilation, air cleaning, etc. by using a microcomputer that is programmed to make passengers feel comfortable. It is composed.

In this FATC system, the position of various doors and the speed of the blower motor are adjusted through logical operations in the microcomputer based on signals input from various sensors and switches.

For example, the controller automatically controls each actuator such as the intake door (internal / external air switching door), the temp door, and the mode door according to the sensor and the switch input, so that the environment of the car (temperature, etc.) is set by the driver. And retaining function.

However, in such a conventional air conditioning apparatus, only simple wind direction control such as room temperature control and air volume control or discharge mode control such as vent, B / L, floor, mix, etc. is possible and necessary. There is no function to discharge the cold air or warm air to the user's desired location.

Therefore, there is an urgent need for a method for increasing the efficiency of the vehicle air conditioning by concentrating air conditioning and heating to a desired location of the user.

Accordingly, the present invention has been invented to solve the above problems, the controller controls the door actuator according to the user position input, so that the cold or hot air passing through the air conditioning device or the heater device is concentrated to each input position selected by the user. It is to be discharged, and through this the car air conditioning and air conditioning can be concentrated to a specific location of the interior space by the user location selection, to provide a centralized control method for heating and cooling by user location input that can increase the efficiency of the indoor air conditioning There is this.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The heating and cooling centralized control method by the user location input according to the present invention,

In the distribution duct, through which a cold or hot air temperature controlled is passed through a heater or an air conditioner, individual branch ducts connected to the respective areas of the vehicle interior space are connected to each other so that the cold and hot air distribution to each branch duct is performed. It is provided with a plurality of doors and actuators for intermittent air flow to each branch duct, and a position input means for allowing the user to selectively input the respective areas,

When the user selects and inputs an area of the vehicle interior space through the location input means, (a) determining, by the location input means, the user input area and comparing the area with the already selected area to determine the final selection area, (b) Determining, by the position input means, an actuator control value according to the final selection area, and outputting a signal corresponding to the control value to the controller of the air conditioning system; and (c) the controller controlling the actuator according to the signal of the position input means. And outputting a signal to control and operate the actuator to intensively discharge cold / hot air only to a region of the vehicle interior space corresponding to the final selection region.

Particularly, as the position input means, a touch screen for selecting and inputting an area of a vehicle interior space where air conditioning and heating is desired and a coordinate signal output from the touch screen are received to perform the steps (a) and (b). Characterized in that the use of the screen drive module.

In addition, the step (a),

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

According to the present invention, the controller controls the door actuator according to the user's position input to increase the efficiency of the vehicle's indoor air conditioning so that the cold air or the warm air passing through the air conditioner or the heater is discharged to each input position. The present invention relates to a heating and cooling concentration control method by a user location input to be concentrated to a specific location of a vehicle interior space.

Typically, as shown in the accompanying FIG. 1, the interior space of a vehicle includes a driver's seat ('zone 1') and a passenger seat ('zone 2'), and a rear left passenger seat ('zone 3') and a right passenger seat (' Region 4 ').

In addition, the conventional vehicle air conditioning system is provided with separate ducts and discharge ports 1a to 1d for individually blowing and discharging cold or warm air into the respective divided areas.

By using this, in the present invention, a plurality of individual branch ducts 121 to 124 connected to respective areas of the vehicle interior space are connected while the temperature controlled cold or hot air passes through the air conditioner or the heater. A plurality of doors 112 to 114 and respective doors for selectively controlling the air flow to the respective branch ducts 121 to 124 in the distribution duct 100 in which the cold / hot air distribution to the 121 to 124 is made. Actuators 112a to 114a for driving 112 to 114 are installed.

For example, as shown in FIG. 2A to FIG. 2C, the distribution duct 100 has an inner space divided into an upper passage 102a and a lower passage 102b by a horizontal wall 101. The rear downstream end of the distribution duct 100 has a structure in which the upper and lower passages 102a and 102b branch again from side to side.

The distribution duct 100 is a duct in which the final distribution of each of the individual branch ducts 121 to 124 is passed through the temperature controlled cold or hot air through the air conditioner or heater in the automotive air conditioning system as described above. .

In addition, the air flow to the upper passageway 102a and the lower passageway 102b toward the inlet side of the upper passageway 102a and the lower passageway 102b, that is, just in front of the transverse wall 101, in the distribution duct 100. A first door 112 that selectively intercepts and an actuator 112a for driving the first door 112 are provided.

Also, in the distribution duct 100, a second control unit selectively intercepts the air flows to the left and right branch passages 103a and 103c immediately in front of the rear downstream left and right branch passages 103a and 103c in the upper passage 102a. Actuator 113a for driving the door 113 and the second door 113 is provided, and the left and right branch passages are similarly directly forward of the respective downstream branch passages 103b and 103d in the lower passage 102b. A third door 114 for selectively intermittent air flow to 103b and 103d and an actuator 114a for driving the third door 114 are provided.

Of course, the actuators 112a to 114a for driving the doors 112 to 114 may be implemented by step motors that are commonly used for driving the doors, and each of the actuators 112a to 114a may be a controller 300 of an air conditioning system. The driving is controlled by the control signal output from

That is, the cold or warm air passes through the upper passageway 102a or the lower passageway 102b in the distribution duct 100 according to the position of the first door 112. In FIG. 2b, the first door 112 is upward. When rotated, the cold or warm air flows only to the lower passageway 102b, and when rotated downward, the cold or warm air flows only to the upper passageway 102a, and in the middle, the upper passageway 102a and the lower passageway 102b All flows through.

In addition, the cold air or warm air passing through the upper passage 102a or the lower passage 102b passes through the left or right branch passage according to the position of the second door 113 or the third door 114. In FIG. When the second door 113 (or the third door 114) is rotated to the left as described above, the cold or warm air flows only to the right branch passages 103a and 103b, and the second door 113 (or the third door 114). If)) is rotated to the right side, the cold or warm air flows only to the left branch passages 103c and 103d, and in the case of being positioned in the middle, both the left and right branch passages flow.

Therefore, finally, the cold or warm air that enters through the inlet of the distribution duct 100 according to the position of each door flows only through the selected place of each of the branch ducts 121 to 124. It can only be provided to the selected area of.

Here, each door actuator, i.e., the door motors 112a to 114a, moves the doors 112 to 114 up / down / down (in the case of the first door) by a control signal output from the controller 300 of the air conditioning system. It is driven to each position of the left / middle / right (in the case of the second and third door), one or two or three selected from the branch duct (121 ~ 124) according to the position of each door (112 ~ 114) If necessary, cold or warm air can be distributed to all four locations.

On the other hand, in order to achieve the object of the present invention, a position input means is required, which is provided to enable the user to selectively input a desired area for heating and cooling, and the touch screen as shown in FIG. 210 and the driving module 220 can be implemented.

The touch screen 210 outputs a coordinate signal corresponding to the screen position contacted by the user's hand to the screen driving module 220 when the user presses each area indicated by a picture or a letter on the screen by the user's hand.

Hereinafter, the process of the present invention in which the heating and cooling is concentrated according to the user position input by the touch screen 210 and the screen driving module 220, the controller 300 of the air conditioning system, and the door actuators 112a to 114a). As follows.

4 is a flowchart illustrating a process of performing a centralized heating and cooling operation according to the present invention.

First, in step S1, when the user selects each area of a picture or a letter displayed on the touch screen 210 as needed and presses it with his or her hand, the touch screen 210 corresponds to a screen position touched by the user's hand. The coordinate signal is output.

Thereafter, the determination unit 221 in the screen driving module 220 acquires the coordinate signal output from the touch screen 210 as described above in step S2, and then inputs the user in the method shown in Table 1 below in step S3. Determine the area.

For example, in the step S3, as shown in Table 1, when the sensing height section and the sensing width section on the touch screen 210, respectively, h and w, the determination unit 221 in the screen driving module is obtained If (x, y) of one coordinate signal is 0 <x <w / 2 and 0 <y <h / 2, it is determined as 'area 1' corresponding to the driver's seat.

Next, the determination unit 221 in the screen driving module determines whether the area input by the user is already selected or not (S41), and if it is determined that the area is not already selected, selects the area input by the user. In operation S42, the selection region is determined as the final selection region (S46).

Next, the motor control value according to the final selection area is determined by the method shown in Table 2 (S47), and then the signal corresponding to the motor control value is output to the controller of the air conditioning system (S48).

Here, the motor control value according to the selection area shown in Table 2 is a value that must be set in advance in the determination unit 221 in the drive module. When the 'region 1' is selected, the control value of the first motor 112a ' The signal corresponding to the control value '+1' of the -1 'and the second motor 113a is output to the controller 300 of the air conditioning system, and the control value signal of the third motor 114a is not output.

Accordingly, the controller 300 receives the signal from the screen driving module 220 to control each motor 112a to 114a as set forth in Table 2 (S5), and eventually each door (by the control operation of the motor) As the rotation of the 112 to 114 is made, concentration of cooling and heating is discharged only to the area input by the user through the individual branch ducts 121 to 124 selected through the distribution air duct 100 through the distribution duct 100 (S6). ).

For example, when 'region 1' is selected, the controller 300 receives a signal output from the screen driving module 220 and transmits a motor control signal to the first motor 112a and the second motor 113a. In this case, a signal for controlling the first motor 112a is output so that the first door 112 rotates downward, and at the same time, the second motor 113a is controlled to rotate the second door 113 to the right. In order to output a signal, the cold air or hot air is discharged only to the driver's seat corresponding to 'Area 1' through the branch duct 121 and the discharge port 1a by the final rotational position of the door.

This case corresponds to a case where a user adds a new area, which will be described later through an example.

On the other hand, when the determination unit 221 in the screen driving module 220 determines that the area input by the user is already selected in step S41, it is determined whether there is another area already selected in addition to the area input by the user (S43). If it is determined that there is no other selection area, the current cooling / hot air discharge mode is continuously maintained (S44).

In this case, the user repeatedly selects the previously selected area again. Since the screen driving module 220 does not output any signal, the centralized air conditioning is maintained in the current mode, and of course, the user operates the air conditioning system. When turned off, the air-conditioning centralized air conditioning by this invention is complete | finished.

However, if it is determined in step S43 that there is another area already selected, the user inputs the selected area (S45), and concentrates the heating and cooling only in the remaining selected mode.

That is, the determination unit 221 in the screen driving module releases the selection of the area input by the user (S45), determines the remaining selection area as the final selection area (S46), and finally selects the method shown in Table 2 below. After determining the motor control value according to the area (S47), the motor control value signal for the remaining selected area is output to the controller 300 of the air conditioning system (S48).

As a result, the controller 300 receives the signal from the screen driving module 220 to control the respective motors 112a to 114a (S5), and eventually, each door 112 to the control operation of the motors 112a to 114a. While the rotation of the 114 is made, the cooling and hot air provided through the distribution duct 100 is discharged to the heating and cooling concentrated only to the selected area remaining through the respective branch ducts 121 to 124 (S6).

In this case, after the user confirms that there are several selection areas through the touch screen 210, the user may leave some areas selected and release an arbitrary area.

Hereinafter, the determination process of the above-described final selection area made by the determination unit 221 of the screen driving module 220 will be described with reference to several cases.

First, when the user selects a new 'zone 2' while the heating and cooling is concentrated with the 'zone 1' selected, the 'zone 1' and the 'zone 2' are final through the steps S41 → S42 → S46. It becomes a selection area.

In addition, when the user selects a new 'zone 3' when the heating and heating is concentrated with the 'zone 1' and the 'zone 2' selected, the 'zone 1' and ' Areas 2 'and' area 3 'are both final selection areas.

In addition, when the user selects the 'zone 2' again while the heating and heating concentration is being performed with the 'zone 1' and the 'zone 2' selected, the 'zone 1' goes through the steps S41 → S43 → S45 → S46. Only the final selection area.

In addition, when the user selects the 'zone 1' again while the heating and heating concentration is being performed with the 'zone 1' selected, the step S41 → S43 → S44 is performed to maintain the current mode. .

In addition, when the user selects 'zone 2' again and then selects 'zone 3' when the heating and heating concentration is being performed with 'zone 1' and 'zone 2' selected, After selection, the process goes from S41 → S43 → S45 → S46 (the selection state of 'zone 2' is released), and then the step from S41 → S42 → S46 ('zone 3' is additionally selected by the selection of 'zone 3'). ), And finally 'area 1' and 'area 3' become selection areas.

Of course, when the final selection area is determined as described above by the steps S47 and S48 and the steps S5 and S6, the screen driving module 220 outputs the motor control value to the controller 300 of the air conditioning system, and thus the controller 300. ) Controls each of the motors 112a to 114a, and as a result of the rotation of each door 112 to 114 according to the motor control, cold or warm air provided through the distribution duct 100 is corresponding to individual branch ducts ( 121 to 124 are concentrated in the heating and cooling is discharged only to the final selection area.

As described above, according to the air-conditioning centralized control method according to the user position input according to the present invention, the controller controls the door actuator according to the user position input to the cold air or hot air passed through the air conditioning device or the heater device to the user selection position Since it can be concentrated discharge, the efficiency of the indoor air conditioning of the vehicle can be increased, and the heating and cooling concentrated position can be adjusted as desired by the user, thereby increasing the convenience.
