Description

Technical Field

[0001] The present disclosure relates to an air conditioning system for a vehicle, and more particularly, to an air conditioning system configured to adjust the temperature and exhaust direction of conditioned air based on various factors such as outdoor temperature and air conditioning load. Background Art

[0002] Recently, electric vehicles have become a potential solution to climate change by implementing environmentally friendly technology while avoiding the use of fossil fuels. Electric vehicles operate using a motor that receives electrical energy from a battery and outputs power. Therefore, electric vehicles have the advantages of reduced emissions, low noise, and motor efficiency that can be higher than the engine efficiency of internal combustion engine vehicles, and therefore they have attracted attention as environmentally friendly vehicles.

[0003] In electric vehicles, the core technology is related to the battery module, and recently, research has been actively conducted on weight reduction, miniaturization, and short charging time of the battery. The battery module needs to be used in an optimal temperature environment to maintain optimal performance and long life. However, due to the heat generated during operation and external temperature changes, it is difficult to use the battery module in an optimal temperature environment.

[0004] In addition, electric vehicles do not have waste heat generated during combustion in a separate engine like an internal combustion engine, and therefore an electric heating device is used to heat the interior of the vehicle in winter. In addition, preheating is required to improve the charging and discharging performance of the battery in cold weather, and therefore a separate coolant heating type electric heater is configured and used. That is, in order to maintain the optimal temperature environment of the battery module, a technology of operating a cooling and heating system for battery module temperature control separately from a cooling and heating system for vehicle interior air conditioning is used.

[0005] Therefore, conventionally, two independent cooling and heating systems are constructed, one for indoor cooling and heating and the other for battery module temperature control.

[0006] In particular, if the energy efficiency of an electric vehicle is not managed during interior cooling and heating, the cruising range is short, long distance travel is not possible, and the comfort of the occupants is reduced because adequate cooling and heating are not provided.

[0007] The contents described above as background art are only for improving the understanding of the background of the present disclosure and should not be regarded as admitting that they correspond to the prior art known to those skilled in the art. Summary of the invention

[0008] Therefore, the present disclosure provides an air conditioning system for a vehicle, which, when providing conditioned air to the interior of the vehicle, adjusts the temperature and exhaust direction of the conditioned air based on various factors such as outdoor temperature and air conditioning load, so as to quickly adjust the indoor temperature to a desired temperature, thereby improving air conditioning efficiency and indoor comfort, and ensuring energy efficiency based on the improved air conditioning efficiency.

[0009] According to one aspect of the present disclosure, the above and other purposes can be achieved by providing an air conditioning system for a vehicle, the air conditioning system comprising: an input device operably connected to the air conditioning device, in which an air conditioning area of ​​conditioned air is assigned to each exhaust outlet; a temperature sensor configured to detect indoor temperature or outdoor temperature; and a controller configured to store a plurality of determination modes, according to each determination mode, determine the temperature or exhaust area of ​​the conditioned air according to the difference between the indoor temperature and the outdoor temperature, and output a control signal transmitted to the input device.

[0010] It is also possible to adjust the exhaust direction in the air conditioning area in the vertical and horizontal directions to adjust the exhaust area.

[0011] It is also possible that the air conditioning device is configured to automatically adjust the discharge direction of conditioned air, and the input device can individually control the discharge direction of the conditioned air of each discharge port.

[0012] It may also be that in the first determination mode among multiple preset determination modes, the controller determines whether to provide heating or cooling by comparing the outdoor temperature input through the temperature sensor with a predetermined set temperature range, sets the exhaust area at the lower part of the air-conditioning area when it is determined to provide heating, and sets the exhaust area at the upper part of the air-conditioning area when it is determined to provide cooling, and outputs a control signal.

[0013] It may also be that in the first determination mode, if the outdoor temperature is lower than the set temperature range, the controller determines to provide heating, if the outdoor temperature is higher than the set temperature range, the controller determines to provide cooling, and if the outdoor temperature is within the set temperature range, the controller determines to provide a mixture of heating and cooling.

[0014] If the outdoor temperature is within the set temperature range, the controller may set the exhaust area at the center of the air-conditioned area and output a control signal.

[0015] Alternatively, in the first determination mode, the controller outputs a control signal so that the conditioned air is discharged to a maximum horizontal area of ​​the air-conditioning area.

[0016] Alternatively, in a second determination mode among a plurality of predetermined set determination modes, the controller determines the air conditioning load by comparing the indoor temperature with the target exhaust temperature, and sets the vertical range of the exhaust area by dividing the air conditioning load into stages.

[0017] The controller may set the vertical range of the discharge area so that the vertical range becomes narrower as the air conditioning load increases and becomes wider as the air conditioning load decreases.

[0018] Alternatively, in a third determination mode among the plurality of predetermined setting determination modes, the controller derives a temperature difference by comparing the indoor temperature with the outdoor temperature, and sets the horizontal range of the discharge area according to the difference between the indoor temperature and the outdoor temperature.

[0019] The controller may set the horizontal range of the discharge area so that the horizontal range becomes narrower as the difference between the indoor temperature and the outdoor temperature increases, and becomes wider as the difference between the indoor temperature and the outdoor temperature decreases.

[0020] The air conditioning system may also include an occupant detector configured to receive information based on the presence or absence and position of an indoor occupant, and the controller performs control so that the conditioned air is discharged only through the exhaust port corresponding to the seat where the occupant is present.

[0021] Alternatively, the occupant detector receives thermal information about the occupant in the room, and if there is a difference between the temperature of the occupant or the surroundings of the occupant and the target exhaust temperature, the controller sets the exhaust area so that the exhaust area includes the occupant.

[0022] The controller may output a control signal so that the exhaust direction of the conditioned air in the exhaust area is repeatedly changed to a vertical direction or a horizontal direction.

[0023] The controller may set the exhaust direction changing period so that the exhaust direction changing period decreases as the difference between the indoor and outdoor temperatures or the air conditioning load increases, and increases as the difference between the indoor and outdoor temperatures or the air conditioning load decreases.

[0024] It is also possible that when the occupant selects the automatic temperature control mode, the controller determines the temperature and the exhaust area of ​​the conditioned air according to each determination mode.

[0025] Alternatively, the controller may not execute the automatic temperature control mode if any of the conditions for defrosting operation are met, there is no input of the indoor temperature or the outdoor temperature, the automatic temperature control mode is turned off, or the ignition is turned off.

[0026] Also provided is a vehicle comprising an air conditioning system. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The controller may include: a communication device that communicates with other controllers or sensors to control their functions; a memory that stores an operating system, logic commands, input / output information, etc.; and one or more processors that perform the determinations, calculations, and decisions necessary for the control functions.

[0044] Hereinafter, an air conditioning system for a vehicle according to a preferred embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0045] like Figure 1 As shown, the air conditioning system for a vehicle according to the present disclosure includes: an input unit 100 (or "input device"), which is used to control the air conditioning device H, in which the air conditioning area A is assigned to each exhaust port 2, and the exhaust direction can be adjusted in the vertical and horizontal directions in each air conditioning area A to adjust the exhaust area B; a temperature sensing unit 200 (or "temperature sensor"), which receives indoor or outdoor temperature; and a controller 300, which stores a plurality of determination modes, and according to each determination mode, determines the temperature of the conditioned air and the exhaust area B according to the difference between the indoor temperature and the outdoor temperature, and outputs a control signal transmitted to the input unit 100.

[0046] As provided herein, the input unit 100, the temperature sensing unit 200 and / or the controller 300 may constitute a module and / or device of an air conditioning system, and may constitute one or more controllers. For example, the above-mentioned units of the air conditioning system may constitute a hardware component (e.g., a module or device of a high-level controller) that forms part of a controller, or may constitute a separate controller having a processor and a memory, respectively. The air conditioning system may include one or more processors and memories.

[0047] The air conditioning device H according to the present disclosure receives cold air or warm air from the HVAC and allows the cold air or warm air to be provided to the interior of the vehicle.

[0048] That is, the air conditioning device H is a ventilation device, and includes a plurality of outlets 2 so that conditioned air can be supplied to indoor occupants. An air conditioning area is allocated to each outlet 2, and the air conditioning area A can be generated so as to include the occupants.

[0049] Furthermore, the air conditioning device H can be configured as a fully automatic ventilation device, in which the exhaust direction of the conditioned air is automatically adjusted. Figure 2 As shown, the air conditioning device H includes a plurality of discharge ports 2 in a housing 1 , each of the discharge ports 2 is provided with a flap to guide the discharge direction of conditioned air, and the position of the flap can be adjusted by a driving unit 3 .

[0050] The air conditioning device H is capable of fully automatically adjusting the exhaust direction of conditioned air in vertical and horizontal directions, and the air conditioning device H may be applied to various embodiments.

[0051] The input unit 100 is provided to control the air conditioning device H and adjust the position of the exhaust area B in the air conditioning area A.

[0052] The input unit 100 can individually control the conditioned air discharge direction of each discharge port 2 and optimize the discharge direction of the conditioned air discharged through each discharge port 2 according to various situations.

[0053] The temperature sensing unit 200 may receive outdoor temperature information through a temperature sensor disposed outside the vehicle, or may receive indoor temperature information through a temperature sensor disposed indoors. As provided herein, the temperature sensing unit 200 refers to one or more sensors disposed inside and / or outside the vehicle, and may also include a processor and / or memory for storing temperature information.

[0054] The controller 300 transmits a control signal to the input unit 100 based on information input through the temperature sensing unit 200, thereby adjusting the position of the discharge area B. Here, the controller 300 may further receive information on a temperature set by a user or a temperature automatically set.

[0055] The controller 300 stores a plurality of determination modes for determining the position of the exhaust area B, determines the temperature of the conditioned air and the exhaust area B according to the difference between the indoor temperature and the outdoor temperature according to each determination mode, and outputs a control signal transmitted to the input unit 100 .

[0056] When the occupant selects the automatic temperature control mode, the controller 300 may determine the temperature of the conditioned air and the exhaust area B according to each determination mode.

[0057] The automatic temperature control mode requires the occupant to set the executed mode, and therefore even if the automatic temperature control mode is executed and the exhaust direction of the conditioned air is adjusted, the occupant is aware of this and does not feel uncomfortable.

[0058] In addition, if any of the defrost operation is satisfied, there is no input of the indoor temperature or the outdoor temperature, the automatic temperature control mode is off, or the ignition is off, the controller 300 does not perform the automatic temperature control mode.

[0059] That is, the automatic temperature control mode is performed in a state where the defrost mode is turned off and indoor and outdoor temperature information is normally collected.

[0060] The defrost mode can be used in certain situations. The defrost mode is given priority, and when the defrost mode is executed, the automatic temperature control mode is not executed.

[0061] Furthermore, if the indoor temperature information and the outdoor temperature information are abnormal, an error may occur in controlling the temperature and exhaust direction of the conditioned air, and thus the automatic temperature control mode is performed if the indoor temperature information and the outdoor temperature information are normally input.

[0062] The determination mode preset in the controller 300 may include the difference between indoor temperature and outdoor temperature, air conditioning load, etc., and by controlling the exhaust direction of the conditioned air according to each condition, the indoor air conditioning efficiency can be improved and the air conditioning satisfaction of the occupants can be ensured.

[0063] The present disclosure describes this in detail. In a first determination mode among a plurality of preset determination modes, the controller 300 may compare the outdoor temperature input through the temperature sensing unit 200 with a preset temperature range to determine whether to provide heating or cooling, set the exhaust area B at the lower part of the air conditioning area A when it is determined to provide heating, and set the exhaust area B at the upper part of the air conditioning area A when it is determined to provide cooling, and output a control signal.

[0064] The first determination mode is for determining whether to provide heating or cooling by comparing the indoor temperature with the outdoor temperature, and for setting an optimal exhaust area B for providing heating or cooling. Therefore, weather information can be further collected in the first determination mode.

[0065] That is, in the first determination mode, the controller 300 compares the outdoor temperature with a predetermined set temperature range. The set temperature range is a temperature range that does not include cold or hot weather conditions and can be set to 5° C. to 30° C. The set temperature range can be set to various temperature values.

[0066] Therefore, the controller 300 determines that heating is required when the outdoor temperature is lower than the set temperature range, and determines to provide warm air. The controller 300 determines that cooling is required when the outdoor temperature is higher than the set temperature range, and determines to provide cold air. In addition, when the outdoor temperature is within the set temperature range, the controller 300 adjusts the indoor temperature based on the set temperature range by determining to provide a mixture of cold air and warm air. Here, when comparing the outdoor temperature with the set temperature range, when determining whether the outdoor temperature is higher or lower than the set temperature range, if the outdoor temperature is higher or lower than the set temperature range by a certain amount, it can be determined whether to provide warm air or cold air.

[0067] In particular, if Figure 3 As shown, when the controller 300 determines to provide warm air, the controller 300 sets the exhaust area B at the lower part of the air conditioning area A. Therefore, the warm air provided from the air conditioning device H moves to the lower part of the air conditioning area A and then diffuses upward, thereby improving indoor heating efficiency.

[0068] In addition, when the controller 300 determines to provide cool air, the controller 300 sets the exhaust area B at the upper part of the air conditioning area A. Therefore, cool air provided from the air conditioning device H moves to the upper part of the air conditioning area A and then diffuses downward, thereby improving indoor cooling efficiency.

[0069] Furthermore, when the controller 300 determines to provide a mixture of warm air and cool air, the controller 300 sets the exhaust area B at the center of the air-conditioning area A so that the indoor temperature can be maintained at a temperature required by the occupants.

[0070] In this way, the controller 300 sets the temperature of the conditioned air provided to the interior of the vehicle according to the outdoor temperature, and outputs a control signal to adjust the position of the exhaust area B in the air conditioning area A according to the temperature of the conditioned air, and thereby can improve the cooling and heating efficiency and enhance the occupant comfort.

[0071] In the first determination mode, the controller 300 may output a control signal so that the conditioned air is discharged to a maximum horizontal area of ​​the air-conditioning area A.

[0072] In this way, when the controller 300 provides conditioned air according to the first determination mode, the controller 300 causes the conditioned air to be discharged to the maximum horizontal area of ​​the air conditioning area A so that warm or cold air is diffused in a wide range indoors to quickly adjust the indoor temperature.

[0073] That is, on the left and right sides of the air conditioning area A of the air conditioning device H, the discharge area B may be set to a maximum range so that conditioned air can be provided to the occupants and the surrounding area.

[0074] In case of the second determination mode among the plurality of preset determination modes, the controller 300 may determine the air conditioning load by comparing the target discharge temperature with the indoor temperature, divide the air conditioning load into stages, and determine the vertical range of the discharge area B.

[0075] That is, in the second determination mode, the controller 300 compares the target exhaust temperature of conditioned air provided to the vehicle interior by the air conditioning device H with the indoor temperature. The target exhaust temperature may be a temperature directly set by an occupant or may be an automatically set temperature.

[0076] Therefore, the controller 300 can determine the air conditioning load according to the difference between the target exhaust temperature and the indoor temperature. If the difference between the target exhaust temperature and the indoor temperature is large, it is determined that the air conditioning load is high, and if the difference between the target exhaust temperature and the indoor temperature is small, it is determined that the air conditioning load is low.

[0077] Here, the controller 300 can divide the air conditioning load into stages and adjust the exhaust area B in the air conditioning area A into a vertical range.

[0078] like Figure 4 As shown, the controller 300 may limit the discharge area B of the conditioned air and provide concentrated conditioned air or provide conditioned air in a wide range by adjusting the vertical range of the discharge area B according to the air conditioning load.

[0079] Specifically, the controller 300 may set the vertical range of the discharge area B so that the vertical range becomes narrower as the air conditioning load increases, and becomes wider as the air conditioning load decreases.

[0080] That is, when the air conditioning load is high, the indoor temperature needs to be changed quickly, and therefore the vertical range of the discharge area B is narrowed so that the conditioned air is discharged in a narrow range in the discharge direction. Therefore, the conditioned air is densely distributed toward the discharge area B set to affect the indoor temperature change, and thus the indoor temperature can be changed quickly.

[0081] In addition, the condition where the air conditioning load is low is a state where the indoor temperature is stable, and therefore the vertical range of the exhaust area B is widened so that the conditioned air is discharged widely in the exhaust direction. Therefore, the conditioned air can be diffused in a wide area indoors, and thus the indoor temperature can be effectively maintained.

[0082] In a third determination mode among the plurality of preset determination modes, the controller 300 may compare the outdoor temperature with the indoor temperature to derive a temperature difference, and set a horizontal range of the discharge area B according to the temperature difference.

[0083] That is, in the third determination mode, the controller 300 compares the outdoor temperature with the indoor temperature to check the temperature difference.

[0084] Therefore, the controller 300 is able to check whether there is heat loss based on the difference between the outdoor temperature and the indoor temperature, and if the difference between the outdoor temperature and the indoor temperature is large, it is determined that there is a large amount of heat loss, and if the difference between the outdoor temperature and the indoor temperature is small, it is determined that there is a small amount of heat loss.

[0085] Here, the controller 300 may set the horizontal range of the discharge area B such that the horizontal range becomes narrower as the difference between the indoor temperature and the outdoor temperature increases, and becomes wider as the temperature difference decreases.

[0086] like Figure 5 As shown, the controller 300 may limit the discharge area B of the air-conditioned air to concentrate the conditioned air or provide the conditioned air in a wide range by adjusting the horizontal range of the discharge area B according to the difference between the outdoor temperature and the indoor temperature.

[0087] That is, in the case where the difference between the outdoor temperature and the indoor temperature is large, the indoor temperature needs to be changed quickly, and thus the horizontal range of the discharge area B is narrowed so that the conditioned air is discharged in a narrow range in the discharge direction. Therefore, the conditioned air is densely distributed toward the discharge area B set to affect the indoor temperature change, and thus the indoor temperature can be changed quickly.

[0088] In addition, the case where the difference between the outdoor temperature and the indoor temperature is small corresponds to a state where the indoor temperature is stable, and thus the horizontal range of the exhaust area B is increased so that the conditioned air is discharged more widely in the exhaust direction. Therefore, the conditioned air can be diffused in a wider area indoors, and thus the indoor temperature can be effectively maintained.

[0089] Each determination mode of the controller 300 may be implemented as a single determination, or two or more determination modes may be implemented simultaneously or sequentially so that control according to the determination mode is performed.

[0090] Meanwhile, the air conditioning system may further include an occupant detection unit 400 (or "occupant detector") that receives information based on the presence or absence and position of indoor occupants. The occupant detection unit 400 can learn the presence or absence and position of indoor occupants through various sensors including cameras or seat detection sensors.

[0091] Here, the controller 300 may control the conditioned air so that the conditioned air is discharged only through the discharge port 2 corresponding to the seat where the occupant exists.

[0092] For example, in the case where only an occupant is sitting on the driver's seat, if the conditioned air is supplied to other spaces including the passenger seat, the air conditioning efficiency and energy efficiency deteriorate. Therefore, if there is an occupant only on the driver's seat, the conditioned air is supplied only to the air conditioning area A corresponding to the driver's seat, thereby preventing the efficiency of the conditioned air from being reduced and providing comfort to the occupant.

[0093] In addition, the occupant detection unit 400 may receive thermal information about the indoor occupant. That is, the occupant detection unit 400 may detect the temperature of the occupant and the temperature around the occupant through a thermal imaging camera installed inside the vehicle.

[0094] Therefore, the controller 300 compares the difference between the temperature of the occupant or the surroundings of the occupant and the target exhaust temperature, and if there is a difference between the temperature of the occupant and the target exhaust temperature, makes the exhaust area B include the occupant in the air conditioning area A corresponding to the occupant.

[0095] For example, Figure 6 As shown, the controller 300 can compare the temperature f around the occupant with the target exhaust temperature through the occupant detection unit 400, and if the difference between the temperature on the occupant side and the target exhaust temperature is above a certain amount, the exhaust area B is set to include the occupant, thereby quickly meeting the occupant's required temperature while reducing the heat load.

[0096] In addition, the controller 300 may output a control signal such that the exhaust direction of the conditioned air in the exhaust area B is repeatedly changed to a vertical direction or a horizontal direction.

[0097] In this manner, the discharge direction of the conditioned air discharged from the air conditioning device H in the discharge area B is repeatedly changed to the vertical direction and the horizontal direction, and thus the conditioned air can be supplied to the entire discharge area B.

[0098] Specifically, the controller 300 may set the exhaust direction changing period so that it decreases as the difference between the indoor and outdoor temperatures or the air conditioning load increases, and increases as the temperature difference or the air conditioning load decreases.

[0099] like Figure 7 As shown, the controller 300 may compare the outdoor temperature with the indoor temperature to check the indoor / outdoor temperature difference and the air conditioning load.

[0100] Therefore, if the difference between the outdoor temperature and the indoor temperature and the air conditioning load are high, the controller 300 can set a short exhaust direction change cycle in the exhaust area B so that the conditioned air is concentrated in the exhaust area B and evenly distributed, and thus the temperature of the space corresponding to the exhaust area B can be quickly changed.

[0101] In addition, if the difference between the outdoor temperature and the indoor temperature and the air conditioning load are low, the controller 300 can set a long exhaust direction change cycle in the exhaust area B so that the conditioned air diffuses relatively slowly in the exhaust area B, and thus the temperature of the space corresponding to the exhaust area B can be stably maintained.

[0102] The air conditioning system for a motor vehicle having the above-mentioned structure adjusts the temperature and exhaust direction of the conditioned air based on various factors such as outdoor temperature and air conditioning load when providing conditioned air to the interior of the vehicle, so as to quickly adjust the indoor temperature to the desired temperature, thereby improving the air conditioning efficiency and indoor comfort, and ensuring energy efficiency according to the improved air conditioning efficiency.

[0103] Although the preferred embodiments of the present disclosure have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the disclosure as disclosed in the accompanying claims.
