IR Module Assembly

[0017] FIG. 1 is a block diagram of an embodiment of an IR module adapted and configured to be installed in a vehicle according to an embodiment of the present disclosure. The IR module 10 comprises at least one IR panel 8, a controller 14 and a power supply 16. In one embodiment, a thermostat 18 is also provided. The IR panel 8 may include multiple panels, or multiple groups of panels. The IR panel 8 is illustrated as a singular panel in the block diagram of FIG. 1 for simplicity. The IR panel 8 may be a FAR IR heating panel. In one embodiment, there are multiple IR panels 8a-n that are independently in communication with the controller. In another embodiment, there are multiple IR panels 8a-n that are in communication with each other and with the controller 14. As such, the invention envisions embodiments in which the IR panels 8a-n are connected together, through a common communication link with the controller 14, as well as embodiments in which there are independent communication links from the IR panel 8 to the controller 14. In addition, the IR panel 8 may be coupled to the controller via wireless or wired communications. The IR panel 8 is adapted and configured to be installed in a roof within the passenger cabin of a vehicle.

[0018] As noted above, the IR panel 8 is electrically and/or communicatively coupled to the controller 14. The controller 14 may include, but is not limited to, elements such as a processor or CPU, random access memory (RAM), read-only memory (ROM), input/output ports, timers and counters, interrupt controls, AC/DC converters, and the like. The controller 14 controls the operation, of the IR panel 8. In doing so, the controller 14 may operate one or more IR panels 8a-n independently, such that the one or more of the IR panels 8a-n may be in one state of operation (e.g., turned on, turned off, rotate horizontal, rotate vertical, 360 degree rotation, constant operation, intermittent operation, battery saver mode, change of radiation level (min-max), etc.), while another IR panel 8 may be in the same or a different state of operation. In addition, the controller 14 is either electrically coupled to, and/or is in communication with a thermostat 18. The thermostat 18 may be part of the vehicle heating system 12. The thermostat 18 may also be a separate thermostat 18 that is part of the IR module 10, as shown in the exemplary embodiment illustrated in FIG. 1. The controller 14 may also be adapted and configured to be electrically connected to or be in communication with other sensors, control systems or elements within the vehicle (e.g., HVAC, seating or motion sensors, user actuated control systems, etc.)

[0019] The IR module 10 includes a power supply 16 which may be independent from the vehicle heating system 12. In an embodiment, the power supply 16 is also independent of any of the vehicle's power system's such as the vehicle battery. In other embodiments, the power supply 16 may be coupled to, charged or recharged by the vehicle's battery. The power supply 16 may be a separate element from the controller 14 as illustrated in FIG. 1. In another embodiment, the power supply 16 is incorporated into the controller 14 or incorporated with the controller 14 for supplying power to the IR panel 8 of the IR heating module 10.

[0020] The power supply 16 is adapted and configured to operate each of the IR panels 8 with a power output within a range of 150-300 Watts. This power range provides the benefit of rapidly heating the interior cabin of the vehicle, while also providing a healthy type of IR radiation for passengers. In an embodiment, an IR panel 8 implemented, for example, using a FAR IR heating panel works in an opposite way from other heating systems. Instead of heating up the air, as conventional heating systems do, the IR panel 8 heats up the objects around it, including the passenger, or human body, which in turn, releases the heat into the air.

Vehicle and IR Module Configuration and Installation

[0021] FIGS. 2 and 3 are illustrations of vehicles 20 and 40 having an infrared (IR) heating module 10 for controlling a climate within the passenger cabin 22 according to embodiments of the present disclosure. The exemplary vehicles 20, 40 may be conventional petrol fuel or diesel operated vehicles. The vehicles 20, 40 may also be an electric, hybrid, autonomous, or other powered vehicle. While the vehicles 20, 40 of FIGS. 2 and 3, respectively, are illustrated as being a conventional sedan having an engine 32, battery 34 and vehicle heating system 12 (FIG. 2 only), the style/make illustrated in these embodiments are only for exemplary purposes. In addition, the elements of the vehicles 20 and 40 are illustrated as being oriented relative to the right, left, rear and front directions provided in the figures. However, these features may be positioned in other locations in the vehicles 20 and 40 as applicable for a given design in which an embodiment of the IR heating module 10 of the present disclosure is implemented. Further, a vehicle heating system 12 is illustrated in FIG. 2 such that the IR heating module 10 is an auxiliary heating mechanism, the present specification envisions that the IR heating module 10 may be the primary and/or sole source of heating passengers and/or objects within the passenger cabin 22.

[0022] In an embodiment, the vehicles 20, 40 have a 12V electric system, which serves as the power supply for the IR panel(s) 8. In this embodiment, the power consumption is approx. 300 W and there is no need for other power supplies. This has the advantage of minimizing power consumption and increasing efficiency. For example, for a ten minute pre-heating of a passenger cabin 22 on a cold morning, only 50 Watts of power is consumed (300 Watts/hour10 min=50 Watts).

[0023] Turning to FIG. 2, the vehicle 20 includes a front portion external to the passenger cabin 22, which houses the vehicle engine 32, vehicle battery 34 and vehicle heating system 12. However, in some embodiments, portions of the vehicle heating system 12 may be located within the passenger cabin 22, for example, partially within the console 36. The passenger cabin 22 is enclosed by a roof 24, which is shown as transparent, and identified by dotted lines, so as to more easily illustrate the components within the vehicle 20 and passenger cabin 22. In this embodiment, the vehicle 20 includes four passenger seats 28a-28d situated between the left and right of the vehicle's four car doors 30a-30d. While this embodiment corresponds to a standard sedan, the vehicle 20 may include any number of seats 28, depending on the style and/or make of the vehicle 20. The passenger cabin 22 also includes a console 36 towards the front of the passenger cabin 22 of the vehicle 20. In an embodiment, the console 36 houses one or more of the controller 14, power supply 16 and thermostat 18 of the IR heating module 10. However, each these elements may be located in other portions of the passenger cabin 22, including the roof 24.

[0024] The vehicle heating system 12 may be a conventional heating system configured to blow forced heated air through vents to warm passengers within the passenger cabin 22 in connection with the operation of the vehicle engine 32. The IR heating module 10 of the present invention may be adapted and configured to work in conjunction with the vehicle heating system 12 as an auxiliary heating option, or alternatively as a primary heating option, with no vehicle heating system 12, as shown in FIG. 3. In addition, the IR heating module 10 may operate independent of the vehicle heating system 12, such that it is the sole method of warming passengers under certain circumstances. For example, in an embodiment, the IR heating module 10 may serve to pre-heat the passenger cabin 22, prior to utilization of the vehicle heating system 12, in response to a user-initiated action or pre-programmed event. These user-initiated action or pre-programmed events may include, but are not limited to: a scheduled or programmable, user-selected warming time, a threshold vehicle cabin 22 temperature reading, an external temperature reading, a door opening, operation of a remote start function, passenger motion sensor reading, passenger seat actuation, passenger voice command, detection of a failure or poor performance of operation of the vehicle heating system 12, change of status of a vehicle engine 32 or vehicle battery 34 operation, and reduction in threshold vehicle fuel level etc.

[0025] According to the present invention, the IR panel 8 is installed in the roof 24 of the vehicle 20 in order to provide the most direct IR radiation to the passenger(s). The IR panel 8 is illustrated in hashed lines to indicate that it is installed within the roof 24, rather than on the same plane and level within the passenger cabin 22 as the seats 28a-28d and other elements within the passenger cabin 24. In the embodiment illustrated in FIG. 2, the IR panel 8 is mounted substantially in the center of the roof 24 of the passenger cabin 22 along a center axis 26 running horizontally along the body of the vehicle 20. In another embodiment, the IR panel 8 is installed along a b-pillar of the roof 24, which those of ordinary skill in the art would understand to be the center pillar of the vehicle 20 between the driver door 30c and the passenger door 30a.

[0026] FIG. 3 illustrates yet another embodiment of a vehicle 40 if the present invention. Similar to FIG. 2, FIG. 3 provides an aerial plan view of the vehicle 40 having an infrared (IR) heating module 10 for controlling a climate within the passenger cabin 22 of the vehicle 40. As noted above, the exemplary IR heating module 10 of FIG. 3 is adapted and configured to provide the primary source of heat for passengers and/or objects within the passenger cabin 22, as no vehicle heating system 12 is provided within the vehicle 40.

[0027] The IR heating module 10 includes a plurality of IR heating panels 8a-8d installed in the roof 24. In this embodiment, the IR heating panels 8a-8d are aligned in the roof 24 substantially above the location of the passenger seats 28a-28d, respectively. While the IR panels 8a-8d are shown as aligned over the passenger seats 28a-28d, one or more IR panels 8a-8d may be installed in and around various locations within the roof 24 of the vehicle. In addition, while only four IR panels 8a-8d are illustrated in FIG. 3, other embodiments of the present invention may provide any number of IR panels 8a-n according to the desired vehicle design. The number (n) of IR panels 8a-n may or may not correspond to the number of passenger or passenger seats within the vehicle 40 according to the present invention.

[0028] Embodiments of the present invention include various positions for the IR panel 8. In one embodiment, illustrated in FIG. 2, a single IR panel 8 may be positioned in the middle of the roof 24. Alternatively, two smaller IR panels 8 may be provided in the roof 24. For example, one IR panel may be provided in front above the center console 36 towards the front of the vehicle 20, and one may provided towards the rear, above the center head rest (not shown). In other embodiments, IR panels 8a-8d may be positioned over each door window, next to the grab handles (not shown). Exemplary dimensions and associated power for the IR panel(s) 8a-n, may be as follows:

[0029] 1 IR panel: power output 300-400 W, length 500 mmwidth 200 mm;

[0030] 2 IR panels: power output 150-200 W, length 250 mmwidth 150 mm; and

[0031] 4 IR panels: power output 100 W, length 150 mmwidth 100 mm.

[0032] The IR panel(s) 8a-n of the present invention are designed to be as compact, and aesthetically pleasing as possible to compliment the interior design of the roof 24. For example, the IR panels 8a-8d may be hidden or relatively invisible to the passenger. To achieve this, in an embodiment, the roof 24, or portions thereof, are covered with an IR transparent and/or opaque fabric material that permits the IR heat waves of the IR panel 8 to be transmitted without making the IR panel 8 visible to the passenger. The fabric may be provided in the roof 24 only at the location of the IR panel 8, or across the entire roofline, or portions thereof. In an embodiment, the dimensions of the vehicle surface area of the vehicle interior or passenger cabin 22 are approximately 2-5 square meters. The surface area dimensions of the IR panel 8 or IR panels 8a-8d may be adjusted according to the vehicle size. Further, the size and number of IR panels 8a-n used may increase or decrease with a desired power output. One benefit and advantage of utilizing multiple IR panels 8a-n is that each of the IR panels 8 may be operated independently. For example, if only one passenger is in the vehicle 40, only the closest or selected IR panel 8a-n may be in operation. Additionally, if one of such IR panels 8a-n is not working, one or more of the remaining IR panels 8a-n1 may still be in operation.

Controller Executed Program/Instructions Stored on a Non-Transitory Machine-Readable Medium

[0033] The present invention includes embodiments of controller program or instructions executed by and/or stored within the controller 14. The controller instructions may be in the form of a computer program, software program, and/or software algorithm programmed on, or stored in a non-transitory machine-readable medium. The controller instructions may include execution of a number of user-initiated or automatic actions, some of which require incorporating signals and outputs form various systems within the vehicle (e.g., heating, HVAC, seating, emergency, weather). These instructions may include, but are not limited to: commands for operation of the IR module 10 based on a temperature of the passenger cabin 22, vehicle engine 32 or vehicle battery 34 availability; pre-programmed commands designed to save or conserve power, fuel or battery life; detection of an emergency vehicle status; and automatic, simultaneous or follow-on operations connected to other user actuated systems such as door opening, remote start, passenger cabin motion detection, and/or passenger seat actuation.

[0034] FIG. 4 is a flow chart illustrating an exemplary embodiment of the operation of a controller program/instruction executed by the controller 14 of the IR module 10 according to the present disclosure. While the steps S1-S4 of the computer program 40 are illustrated in a certain order, one or more of them may occur ongoing, simultaneously, or in a different order than is shown.

[0035] In step 1 (S1), a temperature inside a vehicle passenger cabin or external to the vehicle is detected and sent to the controller 14 of the IR module 10. In step 2 (S2), if a user-initiated action is present, that signal is also provided to the controller 14. In step 3 (S3), the controller 14 receives and processes the signal(s) and determines a course of action based on the stored instructions in the computer program, look-up table or algorithm. In step 4 (S4), a command signal is sent to the one or more IR panels 8. This command could include turning on or off one or more of the IR panels 8a-n, adjusting their output, rotating the IR panel etc. In step 5 (S5), the temperature within the passenger cabin is detected again, and the previously received command is confirmed, and or adjusted based stored instructions, and the process begins again by returning to S1.

[0036] It will be appreciated that some embodiments described herein may include one or more generic or specialized processors (one or more processors) such as microprocessors; Central Processing Units (CPUs); Digital Signal Processors (DSPs): customized processors such as Network Processors (NPs) or Network Processing Units (NPUs), Graphics Processing Units (GPUs), or the like; Field Programmable Gate Arrays (FPGAs); and the like along with unique stored program instructions (including both software and firmware) for control thereof to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of the methods and/or systems described herein. Alternatively, some or all functions may be implemented by a state machine that has no stored program instructions, or in one or more Application Specific Integrated Circuits (ASICs), in which each function or some combinations of certain of the functions are implemented as custom logic or circuitry.
