Embodiments of the present invention relate centrally controlling the environment inside a vehicle including the temperature of a seat.
In conventional vehicles, controlling the temperature of the environment inside a vehicle is separate from controlling the temperature of the seats. Conventional vehicles may include heaters that heat the seat; however, the temperature of the seat is controlled separately from controlling the temperature of the air inside the cabin. Passengers would benefit from the same controller centrally controlling the temperature of the air inside the cabin and the temperature of the seats.
In an example embodiment, a central environmental controller (e.g., control circuit, processing circuit, microprocessor) controls both the HVAC system that sets the temperature of the air in the interior (e.g., inside the cabin) of the vehicle and the heater/coolers in the seats that set the temperature of the one or more seats. The central environmental controller receives information from sensors (e.g., temperature sensors) that are positioned around the interior of the vehicle and in one or more of the seats of the vehicle. The user sets a desired temperature for the interior of the vehicle via a user interface. The central environmental controller controls the HVAC system so that the air temperature inside the cabin is at or near the desired temperature as specified by the user. The environment controller also controls the heater/cooler in each seat so that the temperature of the cover or cushion of the seat is the same as the desired temperature set by the user. The temperature to which the seat is heated or cooled is the same temperature to which the interior of the vehicle is heated or cooled. As the desired temperature is changed, the temperature of the air in the cabin and the seat also change.
In another example embodiment, the central environment controller controls the heater/cooler in the seat so that the temperature of the seat is the desired temperature plus or minus an offset so that the temperature of the seat may be greater than or less than the temperature in the interior of the vehicle. However, the temperature of the seat is related to the temperature of the interior and is controlled (e.g., monitored) by the same controller that regulates the temperature of the interior. Further, as the desired temperature is increased or decreased, the temperature of the seat increases or decreases in accordance with the desired temperature plus or minus the offset.
In any example embodiment, the temperature of the environment inside the vehicle (e.g., interior) and the temperature of the seats are related to the desired temperature provided by the user. Further, the temperature of the interior and the seats are controlled by the same central environmental controller as opposed to having a first controller for controlling the temperature of the interior (e.g., via the HVAC system) and a second unrelated and independent controller for controlling the temperature of each seat.
The vehicle further includes a plurality of ducts and dampers distributed throughout the vehicle. In an example embodiment, a hollow central portion of one or more pillars (e.g., A-pillar, B-pillar, C-pillar) are used as ducts to distribute conditioned air to various portions of the vehicle. Ducts may further include a hollow portion of the roof, a hollow portion of the floor and/or a hollow portion of a door. Ducts include one or more outlets that releases air from the duct into the interior of the vehicle. The distribution of the ducts and outlets around the interior of the vehicle permits the air to be delivered at a lower velocity into the interior than in a conventional vehicle that has ducts solely in the dashboard. Further, the distribution of the ducts and outlets around the interior enable the central environment controller to maintain a desired temperature in a particular region (e.g., zone) of the interior of the vehicle. The central environment controller may use information from temperature sensors positioned around the interior the vehicle to form a temperature map to enable the central environment controller to determine where conditioned air should be delivered via the ducts into the interior to reach or maintain a desired temperature.
Embodiments of the present invention will be described with reference to the figures of the drawing. The figures present non-limiting example embodiments of the present disclosure. Elements that have the same reference number are either identical or similar in purpose and function, unless otherwise indicated in the written description.
In conventional vehicles, the seats may be heated. However, the control of the temperature of each seat is separate from and independent of the other seats and the HVAC system that heats and cools the interior of the vehicle. In other words, in a conventional vehicle, the temperature of the seats and the temperature of the interior are not centrally monitored and/or controlled. A conventional seat is shown in
An example embodiment of the present disclosure relates to a central environmental controller 220, also referred to as controller 220, that controls the HVAC system to heat or cool the interior (e.g., inside, cabin) 260 of a vehicle 200 and the heater/cooler in one or more seats to heat or cool the one or more seats (e.g., 270, 272). In an example embodiment, the controller 220 includes a touchscreen 330 that is part of the environmental control interface 340, also referred to as a user interface. The user may set a desired temperature of the interior 260 and the seats using the environmental control interface 340. In an example embodiment, the controller 220 controls the HVAC system 210 and a heater/cooler 240 and 242 to maintain the temperature of the interior 260, the temperature of a seat 270 and the temperature of the seat 272 to be at or near (e.g., within a threshold) the desired temperature.
In another example embodiment, the controller 220 controls the HVAC system 210 to maintain the temperature of the interior 260 at or near the desired temperature and the heater/cooler 240 and 242 to be at or near the desired temperature plus or minus an offset.
In another example embodiment, the controller 220 controls the HVAC system 210 to maintain the temperature of the interior 260 at or near a first desired temperature, controls the heater/cooler 240 to maintain the temperature of the seat 270 at or near a second desired temperature, and controls the heater/cooler 242 to maintain the temperature of the seat 272 at or near a third desired temperature.
Accordingly, the temperature of the interior 260 and the cover or cushion of the seat 270 or 272 are related to the desired temperature and thereby to each other. Further, the temperature of the interior 260 of the vehicle, the temperature of the seat 270, and the temperature of the seat 272 are all controlled and/or maintained by the controller 220 rather than being controlled by separate controllers that operate independently of each other.
In an example embodiment, only one of the seat 270 or the seat 272 includes a heater/cooler (e.g., 240, 242) and a temperature sensor (e.g., 290, 292).
In another example embodiment, the vehicle includes a plurality of ducts that deliver conditioned air from the HVAC system to various positions inside the vehicle. The positions include physicians at the front, in the center, and/or the rear of the interior the vehicle. Outlets from the ducts deliver the conditioned air at the various positions into the interior of the vehicle. In an example embodiment, the ducts include the hollow portions of the pillars (e.g., A-pillar, B-pillar, C-pillar) of the vehicle, and ducts or hollow portions in the floor, the roof and/or the doors. A plurality of dampers control the flow of the air through the ducts. The controller controls the dampers and thereby the distribution of air through the ducts. Further the controller controls the temperature of the air entering a duct. The controller controls the dampers and the temperature to heat the interior the vehicle, including regions (e.g., zones) of the interior, and the seat to one or more desired temperatures. In an example embodiment, the ducts in the control of the ducts are used to heat the seat to a desired temperature thereby eliminating the need for a heater/cooler from the seat. In another example embodiment, the ducts heat or cool the seat in addition to the conditioned air from the ducts.
In an example embodiment, a heating, ventilation and air conditioning (“HVAC”) system 210 is used to heat, cool, and/or condition (e.g., decrease humidity, remove air-born particles) the air in the interior 260 of the vehicle 200. The HVAC system 210 is used to establish and/or maintain the temperature of the interior 260 of the vehicle 200. Air from the HVAC system 210 heats or cools objects or surfaces of the materials inside the vehicle 200. For example, the air from the HVAC system 210 heats the surfaces inside the interior 260, the seats (e.g., 270, 272, 250), objects placed inside the interior 260, and the people inside the interior 260.
The HVAC system 210 may intake air, work on the air to heat, cool, and/or condition the air and expel the air into the interior 260 of the vehicle 200 as an airflow 230 and/or an airflow 232. In another example embodiment, air from the HVAC system 210 enters the interior 560 of the vehicle 500 as airflows 630-632, 640-646, 650-652, 660, 670, 760, 770,860 and/or 870. The HVAC system 210 may provide air via an airflow at a temperature that is greater than the temperature of the interior 260/560 to heat the interior 260. The HVAC system 210 may provide air via an airflow at a temperature that is less than the temperature of the interior 260/560 to cool the interior 260/560.
In an example embodiment, the HVAC system 210 provides airflows 230, 630, 640-642 and/or 650, collectively referred to herein as driver-side airflow, to the driver-side of the interior 260/560 to heat or cool primarily the driver-side of the vehicle 200/500. The HVAC system 210 provides the airflow 232, 632, 644, 646 and/or 652, collectively referred to herein as passenger-side airflow, to the passenger-side of the interior 260/560 to heat or cool primarily the passenger-side of the vehicle 200/500. In an example embodiment, the desired temperature of the driver-side, and therefore the driver-side airflow, and the temperature of the passenger-side, and therefore the passenger-side airflow, are the same temperature. The user provides (e.g., specifies) the desired temperature to the controller 220 via the environmental control interface 340.
In another example embodiment, the HVAC system 210 provides the driver-side airflow to the driver-side of the interior 260/560 to heat or cool primarily the driver-side of the vehicle 200/500. The HVAC system 210 provides the passenger-side airflow to the passenger-side of the interior 260/560 to heat or cool primarily the passenger-side of the vehicle 200/500. The desired temperature of the driver-side, and therefore the driver-side airflow, may be set independently of the desired temperature of the passenger-side, and therefore the passenger-side airflow. The user may provide the desired temperature to the controller 220 via the environmental control interface 340.
In an example embodiment, the HVAC system 210 is controlled by the controller 220. The controller 220 controls the operation of the HVAC system 210. The controller 220 controls the temperature of the air in the driver-side airflow and the air in the passenger-side airflow. The controller 220 receives information from one or more temperature sensors (e.g., 280-282) regarding the temperature inside the interior 260/560 of the vehicle 200/500. The central environment controller 220 controls the HVAC system 210 which sets the temperature of the driver-side airflow and/or the passenger-side airflow so that the temperature of the interior 260/560 is at or near the desired temperature selected by the user. The controller 220 may use the temperature detected by the temperature sensors 280 and/or 282 to determine whether to increase or decrease the temperature of the driver-side airflow and/or the passenger-side airflow to bring the temperature of the interior 260/560 at or near the desired temperature.
In an example embodiment, the heater/cooler 240 and the heater/cooler 242 are positioned in (e.g., inside, in the interior of) the seat 270 and the seat 272 respectively. The heater/cooler 240 and the heater/cooler 242 are adapted to provide heat to cause the temperature of the seat 270 and the seat 272 respectively to increase. The heater/cooler 240 and the heater/cooler 242 are adapted to remove heat (e.g., cool down, make cold) to cause the temperature of the seat 270 and the seat 272 respectively to decrease. In another embodiment, the heater/cooler 240 and/or the heater/cooler 242 include only a heating element to provide heat. In another embodiment, the heater/cooler 240 and/or the heater/cooler 242 include only a cooling element to remove heat. The heater/cooler 240 and the heater/cooler 242 are adapted to heat and/or cool a cover and/or a cushion of the seat 270 and the seat 272 respectively. A person sitting in the seat 270 or the seat 272 can feel the heat provided to or the heat removed from the cover and or the cushion of the seat.
The heater/coolers 240 and 242 generally are positioned below a cover or a cushion of the seat so that the user does not come into direct contact with the heater/coolers 240 or 242. Each seat may include one or more heater/coolers positioned at various locations (e.g., bottom, back, head rest, sides) of the seat to increase or decrease the temperature of the respective portions of the seats. In an example embodiment, the heater/coolers 240 and 242 are controlled by the controller 220. In an example embodiment, the controller 220 controls the operation of the heater/cooler 240 and the heater/cooler 242 to heat or cool the temperature of the seat 270 and 272 respectively to the same temperature. The temperature to which the seat is heated or cooled is specified by the user (e.g., desired temperature). In another example embodiment, the controller 220 controls the operation of the heater/cooler 240 and the heater/cooler 242 so that the seat 270 is heated or cooled to a different temperature than the seat 272. The user may specify a desired temperature for each seat.
In an embodiment, in which the heater/cooler 240 and/or the heater/cooler 242 comprises a plurality of heaters/coolers positioned at different locations in the seat 270 or the seat 272 respectively, the controller 220 may control the plurality of heater coolers to bring the different locations of the seat 270 or the seat 272 to the same temperature (e.g., the desired temperature). In another example embodiment, the plurality of heater/coolers 240 may bring the seat 270 to a first temperature (e.g., first desired temperature) and the plurality of heater/coolers 242 may bring the seat 272 to a second temperature (e.g., second desired temperature). The first temperature may be different than the second temperature.
In another example embodiment, each heater/cooler of the plurality of heater/coolers of the seat 270 are controlled by the controller 220 to bring each heater/cooler of the plurality of heater/coolers to the same temperature. In another example embodiment, the controller 220 controls one or more heater/coolers of the plurality of heater/coolers of the seat 270 to operate at a first temperature and one or more other heater/coolers of the plurality of heater/coolers of the seat 270 to operate at a second temperature. Regardless of the various temperatures of the different heater/coolers of the plurality of heater/coolers of the seat 270, the operation of each heater/cooler of the plurality of heater/coolers is controlled by the controller 220. The seat 270 may further include a plurality of temperature sensors for detecting the temperature of the various portions of the seat 270 that are heated or cooled by the various heater/coolers of the plurality of heater/coolers. The controller 220 receives the data from the plurality of temperature sensors for controlling the operation of the plurality of heaters/coolers. Another example embodiment, the temperature of the seat 270 may be determined using one or more infrared cameras (e.g., IR camera). The controller 220 may receive the data from the one or more infrared cameras for controlling the operation of the plurality of heaters/coolers.
In an example embodiment, the vehicle 200/500 includes a plurality of temperature sensors that detect temperature. A temperature sensor may be further configured to capture data regarding the temperatures that it detects. The temperature sensor may report (e.g., provide) the data that it captures to the controller 220. The temperature sensor may detect and provide data regarding temperature over any period of time. The temperature sensor may report capture data at any interval.
Each temperature sensor (e.g., 280, 282, 290, 292) detects the temperature of the area surrounding the temperature sensor. Each temperature sensor may capture and report the detected temperature to the controller 220. Each temperature sensor may send temperature data to the controller 220 via a wired and/or wireless communication link. Each temperature sensor may provide temperature data as an analog signal or as digital data. Each temperature sensor may provide temperature data continuously or periodically. A temperature sensor may detect the temperature of the material (e.g., plastic, metal, wood) proximate to the temperature sensor and/or the air proximate to the sensor. A temperature sensor may detect the temperature of the surface (e.g., interior wall, windshield, rear window, steering wheel) of the material proximate to the temperature sensor. A temperature sensor may be embedded in material to detect the temperature of the material. The vehicle 200/500 may include any number of temperature sensors. Temperature sensors may be positioned at any location in the vehicle 200/500.
In an example embodiment, the temperature sensors 280 are positioned on the driver-side of the vehicle 200/500 to detect the temperature of the material and/or the air on the driver-side of the vehicle 200/500. Temperature sensors 282 are positioned on the passenger-side of the vehicle 200/500 to detect the temperature of the material and/or the air on the passenger-side of the vehicle 200/500. Temperature sensor 290 is positioned in the seat 270 to detect the temperature of the seat 270. The seat 270 may include a plurality of temperature sensors 290. Temperature sensor 292 is positioned in the seat 272 to detect the temperature of the seat 272. The seat 272 may include a plurality of the temperature sensors 292. As discussed above, the controller 220 controls the HVAC to bring the air or a surface in the interior 260/560 to be at or near the desired temperature set by the user. The controller 220 controls the heater/cooler 240 and/or the heater/cooler 242 to bring the temperature of the seat 270 and/or the seat 272 to be at or near the desired temperature set by the user. In an embodiment that includes a plurality of temperature sensors in the interior 260/560, the controller 220 may combine the temperature data from the plurality of temperature sensors to determine whether the temperature of the interior 260/560 is at or near the desired temperature. The controller 220 may average the data to determine an average temperature. The controller 220 may compare the average temperature to the desired temperature to determine whether the interior 260/560 is at or near the desired temperature. The controller 220 may detect the lowest temperature, the highest temperature or the median temperature reported by the plurality of temperature sensors as representing the temperature of the interior 260/560. The controller 220 may similarly combine the temperature data from the plurality of temperature sensors 290 and/or the plurality of temperature sensors 292 to determine the temperature of the seat 270 or the seat 272 respectively. The data from a plurality of temperature sensors may be combined in any manner to determine a representative temperature.
In another example embodiment, the temperature in the interior 260/560 of the vehicle 200/500 is determined using one or more infrared cameras (e.g., IR cameras). The IR cameras provide data regarding the temperature of the air and objects on the interior 260/560 in three dimensions. The controller 220 uses the data from the IR cameras to determine the temperature of the air, surfaces and/or objects in the interior 260/560 of the vehicle 200/500. The one or more IR cameras may be positioned around the interior 260/560 of the vehicle 200/500 to provide a 3D picture of the temperature throughout the interior 260/560. The controller 220 receives the data from the one or more IR cameras. The controller 220 uses the data to determine the temperature of a specific location in the 3D volume of the interior 260/560.
The central environmental controller 220, also referred to as the controller 220 herein, controls the operation of the HVAC system 210, the heater/cooler 240, the heater/cooler 242 and as discussed in further detail below dampers in accordance with the temperature data sensed by the temperature sensors 280 — 282, 290 and 292 and/or the one or more IR cameras.
In an example embodiment, the controller 220 controls the operation of the HVAC system 210, the heater/cooler 240, the heater/cooler 242 and the dampers to bring the interior 260/560, the seat 270 and the seat 272 to a desired temperature. In an example embodiment, the user sets a single desired temperature for the interior 260/560, for the seat 270 and for the seat 272. Setting one desired temperature instructs the controller 220 to operate the HVAC system 210, the heater/cooler 240, the heater/cooler 242 and the dampers to bring the interior 260/560, the seat 270 and the seat 272 to the same temperature. The interior 260/560, the seat 270 and the seat 272 do not necessarily reach the desired temperature at the same time. The controller 220 receives data from the temperature sensors 280 and 282 or the one or more IR cameras to determine when the interior 260/560 is at or near the desired temperature. When the interior 260/560 reaches the desired temperature, the controller 220 may cause the HVAC system to stop heating or cooling the driver-side airflow and/or the passenger-side airflow. When the temperature of the seat 270 or the seat 272 reaches the desired temperature, the controller 220 causes the heater/cooler 240 or the heater/cooler 242 respectively to stop heating or cooling the cover or cushion of the seat 270 and the seat 272 respectively. The controller 220 independently controls the HVAC system 210, the heater/cooler 240, the heater/cooler 242 and the dampers to maintain the interior 260, the seat 270 and the seat 272 at or near the desired temperature.
The phrase “at or near” refers to a range of temperature that includes the desired temperature. In an example embodiment, at or near means maintaining the temperature at the desired temperature plus or minus 2 degrees. The amount in the range that deviates from the desired temperature referred to as a threshold. So, the controller 220 operates to maintain the temperature of the interior 260/560, the seat 270 and the seat 272 at the desired temperature plus or minus a threshold (e.g., two degrees, three degrees, so forth). In an example embodiment, the threshold is a range of zero to three degrees.
In an example of an embodiment that uses a single desired temperature to heat or cool the interior 260/560, a user sets the desired temperature to be 70° F. In a situation when the interior 260/560 of the vehicle 200/500, the seat 270 and the seat 272 are presently less than 70° F., the temperature sensors 280, 282, 290 and 292, or one or more RF cameras, initially report a detected temperature of less than 70° F. While the temperature sensors 280, 282, 290, 292 and/or RF cameras detect and report temperatures that are less than the desired temperature, the controller 220 activates the HVAC system 210, the heater/cooler 240, and/or the heater/cooler 242 to provide heat to increase the temperature in the interior 260, the seat 270 and/or the seat 272 respectively. The controller 220 continues to control the HVAC system 210, the heater/cooler 240, and/or the heater/cooler 242 to provide heat until the temperature sensors 280, 282, 290, 292 and/or RF cameras report a detected temperature at or near the desired temperature of 70° F. When the temperature sensors 280, 282, 290, 292 and/or RF cameras detect 70° F., within a threshold, the controller 220 instructs the HVAC system 210, the heater/cooler 240, and/or the heater/cooler 242 to cease heating. The interior 260/560, the seat 270 and the seat 272 may not reach the desired temperature at the same time, so the controller 220 individually controls the HVAC system 210, the heater/cooler 240 and/or the heater/cooler 242. The controller 220 further controls the HVAC system 210, the heater/cooler 240 and/or the heater/cooler 242 independent of each other to operate when needed to maintain the interior 260/560, the seat 270 and the seat 272 at or near the desired temperature. For example, the controller 220 may control the HVAC system 210 to still provide hot air after it has terminated the operation of the heater/cooler 240 and the heater/cooler 242 because the seat 270 and the seated 272 are at or near the desired temperature.
The controller 220 controls the HVAC system 210, the heater/cooler 240, and the heater/cooler 242 to bring the temperature of the interior 260/560, the seat 270, and the seat 272 to the desired temperature set by the user. The desired temperature provided by the user sets the temperature for both the interior 260/560 of the vehicle and the seats 270 and 272. The seats 270 and 272 are both controlled by the controller 220 and not by independent controllers (e.g., 130). Two controllers are independent of each other when they execute separate stored programs with no feedback or information from one controller to the other controller.
The driver-side airflow and the passenger-side airflow play a role in heating or cooling the seats 270 and 272. The temperature sensors 290 and 292 detect the temperature of the seat 270 and the seat 272 (e.g., cover, cushion, interior) respectively regardless of whether the seat 270 and/or the seat 272 are heated by the heater/cooler 240 and the heater/cooler 242 respectively or the driver-side airflow and/or passenger-side airflow. In other words, the heating or cooling of the seat 270 and the seat 272 is related to the heating and cooling of the interior 260/560 of the vehicle 200/500. When the interior 260/560, the seat 270 and/or the seat 272 reach the desired temperature, regardless of the source of heat or cooling, the controller 220 operates to maintain the interior 260/560, the seat 270 and the seat 272 at the desired temperature regardless of whether the HVAC system 210, the heater/cooler 240 or the heater/cooler 242 is operated to maintain the temperature. The temperature of the seats 270 and 272 are not set (e.g., 140) and/or controlled (e.g., 130) separate from the temperature of the interior 260/560. In other words, a common desired (e.g., target) temperature is used to control the HVAC system 210, the heater/cooler 240 and the heater/cooler 242.
In an example embodiment, the HVAC system 210 is used primarily to control the temperature of the interior 260/560 and the temperature of the seats 270 and 272. However, the heater/cooler 240 and the heater/cooler 242 assist the HVAC system 210 in bringing the seats 270 and 272 to the desired temperature more quickly than the HVAC system 210 alone. For example, on a cold winter morning, the HVAC system 210 can take a while to heat the interior 260/560 and the seats 270 and 272 to the desired temperature. However, after the user sets the desired temperature, the heater/cooler 240 and the heater/cooler 242 begin to heat the seats 270 and 272 so that the seats more rapidly reach the desired temperature than relying on the HVAC system 210 alone. Once the temperature of a seat has reached the desired temperature, its respective heater/cooler is turned off. Once the interior 260/560 has reached the desired temperature, the HVAC system 210 alone may be able to maintain the temperature of the interior 260, the seat 270 and the seat 272. The controller 220 may cycle the operation of the heater/coolers 240 and 242 to help maintain the temperature of the seats 270 and 272 at the desired temperature.
Similarly, the heater/cooler 240 and the heater/cooler 242 may assist to cool the seats 270 and 272 more quickly under hot conditions then HVAC system 210 alone. In another example embodiment, the controller 220 operates the HVAC system 210, the heater/cooler 240 and the heater/cooler 242 as needed to cool the interior 260/560, the seat 270 and the seat 272. The controller 220 cycles the operation of the HVAC system 210, the heater/cooler 240 and the heater/cooler 242 as needed to maintain the interior 260/560, the seat 270 and the seat 272 at or near the desired temperature.
In another example embodiment, the user sets a desired temperature for the driver-side (e.g., driver-side desired temperature) of the interior 260 and for the seat 270. The driver-side desired temperature is the same for the interior 260/560 on the driver-side and the seat 270. The user sets a desired temperature for the passenger-side (e.g., passenger-side desired temperature) of the interior 260/560 and for the seat 272. The passenger-side desired temperature is the same for the interior 260 on the passenger-side and the seat 272. The passenger-side desired temperature is the same for the interior 260/560 on the passenger-side and the seat 272. The driver-side desired temperature may be different from the passenger-side desired temperature.
Since the air in the interior 260/560 freely circulates, the final temperature of the air in the interior 260/560 may be somewhere between the driver-side desired temperature and the passenger-side desired temperature. However, since the heat or lack of heat of a seat does not easily transfer to the other seat, the temperature of the seat 270 may be different from the temperature of the seat 272. Further, the controller 220 may operate to maintain the different seat temperatures in accordance with the driver-side desired temperature and the passenger-side desired temperature.
In an example embodiment, the user sets the driver-side desired temperature and the passenger-side desired temperature using icons presented on the touchscreen 330 of the environmental control interface 340 (e.g., user interface). The environmental control interface 340 presents information and an icon for a driver-side temperature 310 and a passenger-side temperature 320. As best shown in
The driver-side desired temperature 312 and the passenger-side desired temperature 322 are provided to the controller 220. The controller 220 uses the driver-side desired temperature 312 to control the temperature of the airflow 230 from the HVAC system 210 and the heater/cooler 240 of the seat 270. The controller 220 controls the HVAC system 210 and the heater/cooler 240 to heat or cool the airflow 230 and at the seat 270 respectively to bring the driver-side of the interior 260 and the seat 270 to the driver-side desired temperature 312. The controller 220 controls the HVAC system 210 and the heater/cooler 242 to heat or cool the airflow 230 and at the seat 272 respectively to bring the passenger-side of the interior 260 and the seat 270 to the passenger-side desired temperature 322.
In an example embodiment, the temperature sensors 280 and 282 measure one or more surfaces on the driver-side and the passenger-side respectively of the interior 260/560, and not the air temperature, to detect the temperature of the driver-side and the passenger-side of the interior 260/560. The temperature sensors 290 and 292 are embedded in the seat 270 and the seat 272 respectively, so they fairly accurately represent the respective temperatures of the seats.
The controller 220 receives data from the temperature sensors 280 and 290 on the driver-side and data from the temperature sensors 282 and 292 on the passenger-side or from one or more IR cameras. The controller 220 compares the data from the temperature sensors 280 and 290, or IR camera, to the driver-side desired temperature 312 to determine when the driver-side of the interior 260/560 and the seat 270 have reached the driver-side desired temperature 312. The controller 220 compares the data from the temperature sensors 282 and 292, or IR camera, to the passenger-side desired temperature 322 to determine when the driver-side of the interior 260/560 and the seat 272 have reached the passenger-side desired temperature 322.
In another example embodiment, the user may specify a first offset to the driver-side desired temperature 312 and/or a second offset to the passenger-side desired temperature 322. The offset is an amount added to or subtracted from the desired temperature. The seat is heated to the desired temperature plus or minus the offset so that the temperature of the seat is different from the temperature of the air in the interior 260/560. For example, the controller 220 controls the HVAC system 210 to heat or cool the driver-side of the interior 260/560 to or near (e.g., within a threshold) the driver-side desired temperature 312 and the heater/cooler 240 to heat or cool the seat 270 to or near (e.g., within a threshold) the driver-side desired temperature 312 plus or minus the offset. Heating or cooling the seat 270 to or near the driver-side desired temperature 312 plus or minus the offset allows the user to have a seat temperature that is warmer or cooler than the driver-side of the interior 260/560. The controller 220 controls the HVAC system 210 and the heater/cooler 240 to maintain the driver-side of the interior 260 and the seat 270 at the different temperatures. For example, the offset is plus 5 degrees, so the controller 220 operates the heater/cooler 240 and the HVAC system 210 maintain the temperature of the seat 270 at a temperature that is 5 degrees higher than the temperature of the interior 260/560.
The second offset for the passenger-side desired temperature 322 accomplishes the same heating or cooling difference between the passenger-side of the interior 260/560 and the seat 272.
In another example embodiment, the user sets a desired temperature for different zones of the interior 560. In this example embodiment, the interior 560 is divided into four regions (e.g., zones): the driver-side front DF562, driver-side rear DR564, passenger-side front PF566 and passenger-side rear PR568 as best shown in
An example embodiment of the controller 220 (e.g., controller 220) includes a processing circuit 410, a memory 412, and the touchscreen 330. The processing circuit 410 communicates with and controls the operation of the HVAC system 210, the temperature sensors 280, 282, 290, 292 and/or IR cameras, and the heater/coolers 240 and 242.
As discussed above, the temperature sensors 280, 282, 290 and 292 and/or the IR cameras detect the temperature of the air in interior 260/560 or and/or a surface of the interior of vehicle 200/500, the temperature of the seat 270 and the temperature of the seat 272. The temperature data detected by the temperature sensors 280, 282, 290 and 292 and/or the IR cameras is reported to the processing circuit 410.
In an example embodiment, the touchscreen 330 receives information from the user regarding the desired temperature for the interior 260/560, the seat 270 and the seat 272. The touchscreen 330 provides the desired temperature to the processing circuit 410. The processing circuit 410 may store the desired temperature in the memory 412. In another example embodiment, the touchscreen 330 receives information from the user regarding the desired temperature of the interior 260/560 and an offset so that the seat 270 and/or the seat 272 are heated or cooled to the desired temperature plus or minus the offset. The processing circuit 410 receives the desired temperature and the offset from the touchscreen 330. The processing circuit 410 may store desired temperature and the offset in the memory 412.
In another example embodiment, the touchscreen 330 receives information from the user regarding the driver-side desired temperature for the driver-side of the interior 260/560 and the seat 270 (e.g., 312), and the passenger-side desired temperature for the passenger-side of the interior 260/560 and the seat 272 (e.g., 322). The processing circuit 410 receives the driver-side and passenger-side desired temperatures from the touchscreen 330. The processing circuit 410 may store the driver-side and passenger-side desired temperatures in the memory 412.
In another example embodiment, the touchscreen 330 receives information from the user regarding the driver-side desired temperature and a driver-side offset. The touchscreen 330 also receives information from the user regarding a passenger-side desired temperature and a passenger-side offset. The processing circuit 410 receives the driver-side desired temperature, the driver-side offset, the passenger-side desired temperature and the passenger-side offset. The processing circuit 410 may store the driver-side desired temperature, the driver-side offset, the passenger-side desired temperature and the passenger-side offset in the memory 412.
In another example embodiment, the touchscreen 330 receives information from the user regarding a desired temperature for the driver-side front DF562, driver-side rear DR564, passenger-side front PF566 and passenger-side rear PF568 regions of the interior 260/560. The processing circuit 410 receives the desired temperatures for the driver-side front DF562, driver-side rear DR564, passenger-side front PF566 and passenger-side rear PF568 regions and may store the desired temperatures in the memory 412.
The processing circuit 410 controls the HVAC system 210 to heat or cool the interior 260/560 as a whole (e.g., single desired temperature), as driver-side and passenger side (e.g., driver-side desired temperature, passenger-side desired temperature) or as regions (e.g., desired temperatures for DF562, DR564, PF566, PF568 regions). The processing circuit further controls the heater/cooler 240 and the heater/cooler 242 to heat or cool the seat 270 and 272 to the desired temperature (e.g., driver-side, passenger-side, DF562 region, PF566 region) including our not including an offset. The seat 250 may also have one or more heater/coolers that are controlled by the processing circuit 410 in accordance with an appropriate desired temperature.
In an example embodiment, the processing circuit 410 controls the touchscreen 330 to receive information from and present information to the driver. In the example shown in
In another example embodiment, best seen in
The processing circuit 410 may execute a stored program to perform the functions of the controller 220. The program executed by the processing circuit 410 may be stored in the memory 412. The processing circuit 410 may also store and retrieve data to and from the memory 412 respectively. For example, the desired temperature, the offset, the driver-side desired temperature, the passenger-side desired temperature, the driver-side offset and/or the passenger-side offset may be stored in the memory 412 as mentioned above.
In another example embodiment, the touchscreen 330 may be replaced by a display (e.g., monitor, LCD screen, segmented display) for presenting information to the user and a touchpad for receiving information from the user. The user may move their finger up or down on the touchpad to control the position of the sliders 314 and 324 of the environmental control interface 340. The user may press an upper portion of the touchpad or a lower portion of the touchpad to activate the up arrows (e.g., 350, 354, 358, 362) and down (e.g., 352, 356, 360, 364) arrows respectively of the environmental control interface 342. In another example embodiment, the siders and arrows of the environmental control interfaces 340 and 342 may be implemented using electro-mechanical controls (e.g., sliders, buttons).
In the example embodiment of the vehicle 200, the HVAC system 210 provides conditioned air via ducts located in the front of the vehicle, primarily from the dashboard while the seats were heated or cooled using the heater/coolers 240 and 242. In the example embodiment of the vehicle 500, the HVAC system 210 provides airflow via ducts that substantially surround the interior of the vehicle while the seats 270 and/or 272 are heated/cooled primarily using the heater/coolers 240 and 242. The seat 250 may also be heated or cooled using one or more heater/coolers. In some example embodiments of the vehicle 500, air from the HVAC system 210 heats or cools the seats 250, 270, 272 sufficiently so that the heater/coolers 240 and 242 may be omitted.
In an embodiment in which the HVAC system 210 provides air via a plurality of ducts that substantially surround the interior of the vehicle, the controller 220 controls HVAC system 210 and the heater/coolers 240 and 242 if present. The controller 220 may further control the amount of flow of air and the temperature of the air that flows through a particular duct. For example, the controller 220 may control dampers (not shown) that control the amount of flow of air through one or more ducts.
Further, the information from the temperature sensors 280, 282, 290 and 292 and/or the IR cameras may be used to create a map of the temperature (e.g., temperature map) of the interior 260/560 of the vehicle. The controller 220 may use the temperature map in combination with the desired temperature (e.g., single, driver-side, passenger-side, regions) to control airflow through the ducts and the temperature of the air that flows through the ducts to heat or cool particular areas of the interior 260/560 to reach the desired temperature.
In an embodiment that includes a plurality of ducts (e.g., vehicle 500), the flow of air need not be as high (e.g., strong, forceful) is in an embodiment where the ducts are primary located in the dashboard (e.g., vehicle 200). Further, in an embodiment that includes a plurality of ducts, the interior 560 may be divided into zones (e.g., driver-side, passenger-side, DF562, DR564, PF566, PR568) where different zones may be maintained at different temperatures within reason. Further, the controller 220 may monitor the information of the temperature map to try to maintain the different zones at the desired temperature for the zone. Any number of temperature sensors (e.g., 280, 282, 290, 292, IR cameras) may be positioned throughout the interior 260/560 to detect the temperature of the air and/or surfaces. Each temperature sensor may detect and represent a particular portion of the interior in the temperature map. Further, sensors may be included in the interior of the seat 250 to control of the temperature of the seat 250.

Generally, the interior of a pillar is hollow to reduce the weight of the vehicle. The hollow interior of a pillar may be used as a duct to transport conditioned air. Only the A-pillar, B-pillar and C-pillar on the driver's side are shown in
Any number of dampers may be positioned between the ducts and/or on the outlets to regulate the flow of air between the ducts and/or out of an outlet into the interior 560. Dampers are not explicitly shown in the drawing but may be positioned at any location to control any flow of air. Some dampers at outlets may be controlled manually by user. However, most dampers are controlled by the controller 220. The controller 220 controls the dampers to regulate the flow of air in the interior 560 and toward the seats 270, 272 and 250. The controller 220 may control dampers to regulate the flow of air in accordance with the temperature map. The controller 220 may control dampers to increase or decrease the temperature of a flow through a particular duct and thereby the temperature of a portion of the vehicle 500.
In an example embodiment, as best seen in
In this embodiment, a portion of airflow 640 is directed toward the seat 270. The airflow may be used to heat or cool the seat 270; however, heating and cooling of the seat 270 may benefit from the heater/cooler 240. Accordingly, the heater/cooler 240 and 242 are not omitted from the seats 270 and 272.
In another example embodiment, as best seen in
In this embodiment, a portion of airflow 760 is directed toward and even upward into the interior of the seat 250, the seat 270 and/or the seat 272. The outlets from the floor duct 710 may be positioned directly underneath the seat 250, the seat 270 and/or the seat 272, so that the air that flows from those ducts directly heats or cools the seats 250, 270 and/or 272. Outlets that direct air from the floor ducts 710 and 712 toward a seat may include dampers that assist in controlling airflow to and the temperature of the seats. The seats 250, 270 and 272 may include ducts internal to the seat that fit over an outlet from the floor ducts 710 or 712. Air from the floor ducts 710 or 712 may flow into ducts that are positioned inside the seats. The ducts inside the seats may have outlets that direct air into or against a cover and/or cushion of the seat thereby heating or cooling the seat using air from the HVAC system 210. In this embodiment, the heater/coolers 240 and 242 may be omitted from the seat 270 and 272 because the air provided by the HVAC system 210 via the plurality of ducts heats or cools the seats.
In another example embodiment, best shown in
In this example embodiment, the hollow interiors of the doors 810 and 812 serve as ducts along with the A-pillars 510/512, the B-pillars 520/522 and the C-pillars 530/532 to distribute air around and into the interior 560. The vehicle 500, in this embodiment, may further include dampers between the A-pillars 510/512 and the door 810, the door 810 and the B-pillars 520/522, the B-pillars 520/522 and the door 812, the door 812 and the C-pillars 530/532. Air flows from the A-pillars 510/512, the door 810, the B-pillars 520/522, the door 812 and the C-pillars 530/532 as airflows 630, 860, 640, 642, 644, 646, 870, 650 and 652 respectively. Airflows 630, 860 and 640 provide air primarily to the driver-side front zone DF562. Airflows 642, 870 and 650 provide air primarily to the driver-side rear zone DR564. Airflows 632, 860 and 644 provide air primarily to the passenger-side front region DF566. Airflows 646, 870 and 652 provide air primarily to the passenger-side rear region DR568.
In this embodiment, a portion of airflow 860 and airflow 870 are directed toward the seat 270 and the seat 250 respectively. It is possible that airflow 860 and airflow 870 are sufficient heat or cool the seat 270 and the seat 250; however, heating and cooling of the seats (e.g., seat 270) may benefit from a heater/cooler (e.g., heater/cooler 240) inside the seat. Accordingly, the heater/coolers 240 and 242 are not omitted from the seats 270 and 272.
The ducts from any of the above embodiments may be included in a new embodiment. For example, the vehicle 500 may include any combination of pillar ducts, roof ducts, floor ducts and door ducts. For example, the vehicle 500 may use the A-pillars 510/512, the B-pillars 520/522, the C-pillars 530/532, the roof duct 610, the roof duct 612, the floor duct 710, the floor duct 712, the door 810 and the door 812. In another embodiment, the vehicle 500 includes the A-pillars 510/512, the B-pillars 520/522, the C-pillars 530/532, the floor duct 710 and the roof duct 612. Any combination of ducts may be used that circulates air around and into a majority of the interior 560.
As discussed above, temperature sensors (e.g., 280, 282, 290, 292) and/or the IR cameras may be placed anywhere in the interior 560 to detect the temperature of the air, an object or a surface. The temperature sensors and/or the IR cameras may provide data to the controller 220. The controller 220 may prepare a temperature map, as best seen in

With respect to the temperature map of
Because the conditioned air from the HVAC system 210 is delivered to the interior 560 via a plurality of ducts, the velocity of the airflow through the plurality of ducts does not need to be as high as the velocity of the air delivered primarily through outlets located in the dashboard. For example, for a duct whose outlet is positioned near the dashboard to deliver conditioned air to the rear of the vehicle, the air must exit the outlet of the duct at a high velocity to reach the back of the vehicle. Air that is delivered through a duct to an outlet positioned in the rear of the vehicle may exit the outlet at a much lower velocity because the duct has delivered the conditioned air to the rear of the vehicle for release from an outlet positioned in the rear of the vehicle. The velocity of air through a duct may be modulated (e.g., controlled) by dampers that control the flow of air through the duct or through the speed of the fan that supplies air to the duct. If one duct feeds (e.g., provides, supplies) other ducts, the speed of the fan may need to be increased to supply the flow of air through the ducts positioned serially and dampers used to control the speed of the air exiting the outlets of the ducts.
The HVAC system 210 may include a plurality of fans the drive conditioned air into the plurality of ducts. The controller 220 may control the plurality of fans to provide air to different ducts at different velocities. The controller 220 may control the temperature of the air provided by the HVAC system 210 to the plurality of ducts so that the temperature of air in some ducts is greater than the temperature of air in other ducts. The controller 220 may control the temperature and/or the velocity of the air in the plurality of ducts to bring the interior 560, or a portion thereof, to a desired temperature.
Providing conditioned air to the interior 560 at reduced velocity means that the controller 220 may more effectively control the temperature in regions of the vehicle because there is less turbulence and mixing of the air at the boundaries of the regions. Further, delivering air through a plurality of ducts that include a plurality of dampers that are controlled by the controller 220 increases control of the air delivered to the different zones of the vehicle.
