As shown in Figure 1, the temperature control system 10 according to an embodiment of the present invention is the first to L-th wind direction controller (110_1 ~ 110_L), the first to N-th pressure sensor (130_1 ~ 130_N), the user interface The unit 140 and the controller 120.

Here, the temperature control system 10 according to an embodiment of the present invention may be an air conditioner, a heater, an air conditioner, or the like, and when the temperature control system 10 is an air conditioner, the vents output cold air, and in the case of the heaters, the vents may provide warm air. Output, and in case of air conditioner, outputs outside air.

The first to L th wind direction controllers 110_1 to 110_L adjust the wind direction of cold air, warm air, or outside air (hereinafter referred to as “wind”) supplied to the vehicle interior according to a command of the controller 120.

The first to L th wind direction controllers 110_1 to 110_L are respectively provided at each of the ventilation holes, and automatically adjust the direction of each of the ventilation holes that have been opened and closed manually, or operated up, down, left, and right according to a command of the controller 120. In this case, L may correspond to the number of vents.

For example, the wind direction controllers 110_1 to 110_L adjust the opening and closing direction of the wind by applying a pushing or pulling force to the rear of the ventilation opening through which the wind is input or in front of the ventilation opening through which the wind is output. It can be a mechanical device to regulate.

The first to Nth pressure sensors 130_1 to 130_N are respectively provided on the chair seats of the plurality of vehicle seats, and detect the pressure of each seat. In this case, N may correspond to the number of vehicle seats.

For example, in the case of a passenger car having five seats, five pressure sensors 130_1 to 130_5 are respectively provided on the seats of five seats, and detect the pressure of each seat.

The user interface unit 140 is a button and a display, etc., and receives a passenger's operation such as on / off control, air conditioner temperature setting, temperature auto / manual control setting, and displays an air conditioner operation state.

The controller 120 checks whether the automatic temperature control is set when driven on and driven by the occupant's operation, and uses the pressure sensed by the first to Nth pressure sensors 130_1 to 130_N when the automatic temperature control is set. To identify the location of all occupants in the seats of the vehicle.

The controller 120 may determine the position of the seat where the pressure detected by the first to Nth pressure sensors 130_1 to 130_N is greater than or equal to a predetermined threshold pressure as the occupant's position. Here, the threshold pressure is a reference pressure for determining whether the occupant is, and may be determined by experiment.

The controller 120 adjusts the direction of each vent and the intensity of the wind output to each vent in consideration of the positions of all the occupants in the vehicle so that the wind is uniformly supplied to all the occupants in the vehicle.

On the other hand, when the occupant does not want to be supplied with the wind, the user interface unit 140 may request not to output the wind to the seat on which he boarded. In this case, the controller 120 may close the air vent that outputs the wind to the seat, or adjust the direction of the air vent so that the wind is not supplied to the seat. Therefore, the temperature control system 10 of the present invention can consider the occupants who do not like the wind of the air conditioner or heater.

Hereinafter, a specific example in which the controller controls the direction and intensity of the wind will be described with reference to FIG. 2. 2 is a view showing a vehicle having ①, ②, ③ and ④ vents according to an embodiment of the present invention.

For example, when one passenger sits in the driver's seat, the controller 120 controls each of the wind direction regulators 110_1 to 110_L to adjust the ① and ② vents toward the driver's seat, and the ③ and ④ vents to be closed. ③ and ④ The vent can prevent the wind from outputting.

In another example, when two occupants sit in the driver's seat and the passenger seat, the controller 120 controls each of the wind direction controllers 110_1 to 110_L to adjust ① and ② vents toward the driver's seat, and ③ and ④ vents to the passenger seat. Can be adjusted to face.

In another example, when four passengers are seated in the driver's seat, the passenger seat, the left rear seat and the right rear seat, respectively, the controller 120 controls the respective wind direction regulators 110_1 to 110_L to adjust the ventilation holes toward the driver's seat, ④ Vents can be adjusted toward the passenger seat, ② vents to the right of the rear seats, ③ vents can be adjusted to the left of the rear seats.

On the other hand, the controller 120 may control the intensity of the wind output through each vent in consideration of the distance between each vent and the occupant.

For example, the controller 120 outputs wind of the first intensity when the direction of the vent hole is directed toward the driver's seat or the passenger seat, and outputs the wind of the second intensity greater than the first intensity when it faces the rear seat. Can be.

Hereinafter, a temperature control method according to an embodiment of the present invention will be described with reference to FIG. 3. 3 is a flowchart illustrating a temperature control method according to an embodiment of the present invention.

Referring to FIG. 3, when the temperature control system 10 is turned on according to a passenger's operation (YES in S310), the temperature control system 10 checks whether automatic temperature control is set by the passenger (S320).

When the automatic temperature control is set, the temperature control system 10 checks the pressure for each seat detected by the pressure sensors 130_1 to 130_N, and determines the position of the seat where the occupant is seated whose pressure is greater than or equal to the threshold pressure. S330).

The temperature control system 10 adjusts the direction and strength of the ventilation openings in consideration of the positions of the seats of all the passengers in the vehicle to supply wind to all the passengers (S340).

Specifically, the temperature control system 10 controls the mechanical device to adjust the direction and opening and closing of the vents by applying a force to push or pull the plurality of vents to supply wind to the seat seated by the occupants in the vehicle, the occupants do not sit Empty seats may not provide air.

In addition, the temperature control system 10 may provide a stronger wind than when the occupant sits in a seat (eg, the front seat) closer to the seat (eg, the back seat) relatively far from the vent.

If the automatic temperature control is not set by the occupant, the temperature control system 10 outputs wind through all the ventilation holes provided without separately controlling the pressure sensing, the direction and the intensity of the ventilation holes for each seat (S350). At this time, the occupant can adjust the opening, closing and direction of the vent opening by hand.

As such, the present invention may improve the convenience and efficiency of temperature control by adjusting the direction and intensity of the cold or warm air supplied by the air conditioner or the heater in consideration of the occupant's position.

In addition, the present invention may not supply cold air, warm air or outside air to the passengers who do not want to supply the wind, and can adjust the temperature in consideration of the selection of each passenger.

While the present invention has been described in detail with reference to the accompanying drawings, it is to be understood that the invention is not limited to the above-described embodiments. Those skilled in the art will appreciate that various modifications, Of course, this is possible.
