DETAILED DESCRIPTION

(7) Reference is now made to FIG. 1 schematically illustrating the volatile organic compound (VOC) purge system 10 for a motor vehicle V. As illustrated, the system 10 incorporates a blower 12 and a computing device in the form of a controller 14.

(8) The blower 12 is a part of the standard vehicle ventilation system. The controller 14 may comprise a body control module (BCM). As illustrated in FIG. 2, the controller or BCM 14 comprises a computing device having one or more processors 18, one or more memories 20, one or more network interfaces 22, a human interface 24, a GPS/Geo locator component 26, a display device such as a multi-function display with touchscreen capability 28 and a speech processor 30 that all communicate with each other over a communication bus 32. The controller or BCM 14 performs a number of interior body electrically based functions including, for example, interior locking, remote key entry, interior lighting, exterior lighting, windshield wiper control and the like. In some embodiments the controller or BCM 14 may also function to control entertainment functions (e.g. radio, CD player and communications such as telephone and internet communications over a wireless network). In some embodiments the controller or BCM 14 is connected by a communication bus (not shown) to other control modules that provide one or more of these additional functions.

(9) The controller 14 is configured to operate in shipping mode whereby the blower 12 is periodically operating to draw fresh air into and purge the VOCs from an interior I of the of the motor vehicle V as the motor vehicle is being shipped from a first point to a second point such as from a vehicle manufacturing facility to a retail vehicle dealership.

(10) As further illustrated in FIG. 1, the controller 14 includes a timer component 34 that times the operation of the blower 12 after each activation. Once the blower 12 has been operating for a predetermined period of time such as, for example, two to four minutes, the controller 14 terminates operation of the blower 12.

(11) As further illustrated in FIG. 1, the controller 14 also includes a counter component 36 for counting each blower activation. When the activation count reaches a predetermined number such as 20, 60 or even 80 blower activations, the controller 14 terminates the operation of the purge system 10 thereby forgoing any more periodic activations of the blower 12.

(12) As further illustrated in FIG. 1, the controller 14 is connected to a voltage sensor 38 which monitors the voltage of the vehicle battery 40. The controller 14 is configured to terminate the periodic operation of the blower 12 whenever the voltage of the battery 40 falls below a predetermined minimum voltage level as detected by the voltage sensor 38.

(13) As further illustrated in FIG. 1, the blower 12 is part of the standard motor vehicle ventilation system. When activated and operating, the blower 12 functions to draw fresh air into the intake 42 and through the filter 44 in the filter box 46 before forcing that fresh air through the outlet 48 into the interior I of the vehicle V. Here it should be appreciated that the filter 44 in the filter box 46 during the shipping of the vehicle from the first point to second point is a particle filter that replaces the standard HVAC filter of the ventilation system. For purposes of this document the terminology particle filter includes particle filters, screens and woven or nonwoven filter materials of any appropriate type. The particle filter 44 is characterized by significantly less airflow resistance than the standard HVAC filter thereby reducing the current drawn by the blower 12 during blower operation upon each activation during shipping mode. Advantageously this helps conserve the electrical power in the battery 40. The standard HVAC filter 50 may be placed anywhere in the motor vehicle V. Accordingly, upon reaching the shipping destination point, one can quickly and easily replace the particle filter 44, specifically adapted for shipping mode operation, with the standard HVAC filter 50 specifically adapted for standard operation of the ventilation system in the motor vehicle.

(14) As further illustrated in FIG. 1, the system 10 also includes a window insert 52 that is positioned in a window opening 54 of the motor vehicle above a partially opened window 56 in one of the vehicle doors 58. The insert 52 may be made from injected molded plastic. As schematically illustrated in FIG. 3, the window insert 52 includes a channel 60 for receiving the top edge of the window 56 and a positioning flange 62 for engaging in the window seal at the top of the window opening 54. Thus, it should be appreciated that the window insert 52 is captured in the window opening 54 between the window seal and the window 56, extending completely across that opening as illustrated in FIG. 1.

(15) As further illustrated in FIG. 3, the window insert 52 includes an airflow pathway 64. When the controller 14 activates the blower 12, fresh air is drawn into the intake 42 and passes through the filter 44 into the blower 12 before being forced from the outlet 48 into the interior I of the vehicle V (note action arrows A). This air sweeps potentially VOC contaminated air within the interior I forcing it to pass through the air flow pathway 64 in the window insert 52 and exit the vehicle (note action arrows B in FIGS. 1 and 3). A rain shield 66 overlies the pathway 64 thereby effectively preventing rain and water intrusion into the interior I of the vehicle V through the pathway 64. One or more screens or grid structure 68 extending completely across the airflow pathway 64 prevent insect intrusion into the interior I of the vehicle V through the pathway.

(16) As further illustrated in FIG. 1, in one possible embodiment the purge system 10 also includes one or more filter packs 70 that may be positioned anywhere in the interior I of the vehicle V. Each filter pack 70 may be charged with activated carbon or some other VOC absorbing material and functions to remove VOCs from the air inside the vehicle V even when the blower 12 is between periodic operating cycles. This helps to further clear the VOCs during shipping.

(17) As should be appreciated from above, the VOC purge system 10 functions in accordance with a method of purging volatile organic compounds from a motor vehicle during the shipping of the motor vehicle from a first point to a second point. That method includes initiating shipping mode of the controller 14 prior to shipping the motor vehicle V from, for example, a manufacturing facility to a retail vehicle dealership. When operating in shipping mode, the computing device or controller 14 in the motor vehicle V activates the blower 12 in a manner necessary to periodically draw fresh air into and purge volatile organic compounds from the interior I of the motor vehicle V. This activation occurs at predetermined intervals of time such as, for example, once a day. Further, the controller 14, consistent with a timer component 34 operates the blower 12 for a predetermined operating time after each activation.

(18) Consistent with the method, the voltage sensor 38 monitors the voltage of the vehicle battery 40. In the event that the battery voltage falls below a predetermined minimum level, the controller 14 terminates the operation of the blower 12. Consistent with the counter component 36 of the controller 14, each activation of the blower 12 is counted and further activation is terminated upon the activation count reaching a predetermined value.

(19) Upon reaching the desired destination, or prior to delivery to the final customer the method includes terminating the shipping mode of operation of the controller 14 and replacing the particulate filter 44 in the filter box 46 with the standard HVAC filter 50 that was previously stored in the motor vehicle V during shipping.

(20) An operational flowchart clearly and concisely illustrating the operation of one possible embodiment of the VOC purge system 10 is set forth in FIG. 4.

(21) The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breath to which they are fairly, legally inequitably entitled.
