Screen cleaning system for a motor vehicle

## Abstract

A screen cleaning system for a motor vehicle includes a screen cleaning device and a dedicated receiver for holding the screen cleaning device. That receiver is integrated into the interior trim of the motor vehicle.

## Background
TECHNICAL FIELD
This document relates generally to the motor vehicle equipment field and, more particularly, to a screen cleaning system as well as to a touchscreen for a motor vehicle.
BACKGROUND
Motor vehicles are often equipped with display screens in the center stack or other areas. These may be used for a number of purposes and may display vehicle information relating to, for example, the entertainment system, the navigation system, the climate control system, the time, vehicle operating parameters or the like. Many vehicles now incorporate rear view cameras and the video image from such a camera may also be displayed on the screen to aid when backing up a vehicle.
In addition, many motor vehicles today are equipped with touchscreens thereby effectively turning the screen into a control panel and allowing the elimination of various switch gear from the center stack and instrument panel for a cleaner uncluttered appearance.
While these screens provide a number of benefits and advantages and are becoming more and more popular, it should be appreciated that they are also prone to unsightly finger prints. Further, dust tends to collect on these screens over time. Up until the present, the operator has had to bring a cloth and cleaning solution into the vehicle every time he wished to clean the screen or store such cleaning supplies inside the center console, door pockets or glove box of the vehicle where they occupy storage that could be used for other items and are loosely held and free to shift around and create annoying rattles and noise during vehicle operation.
The screen cleaning system disclosed in this document addresses this problem by providing a screen cleaning device and a dedicated receiver integrated into the interior trim that holds the screen cleaning device.

DETAILED DESCRIPTION
Reference is now made to FIG. 1 illustrating a first embodiment of screen cleaning system 10. As best illustrated in FIG. 1, that screen cleaning system 10 includes a screen cleaning device 12 comprising a base 14 having a cleaning pad 16 on one side and a projecting handle 18 on the other side. In one possible embodiment the cleaning pad 16 is a dry pad of microfiber material.
A second embodiment of screen cleaning device 12 is illustrated in FIGS. 2a and 2b. As illustrated in FIG. 2a, that screen cleaning device 12 is held in a dedicated receiver 20 when not in use. That receiver 20 may be integrated into the interior trim of the motor vehicle at various locations including, for example, the center stack 22 adjacent a viewing screen 24 (see FIG. 2a). It should be appreciated that the center stack position for the receiver 20 is merely presented for purposes of illustration and description and that other locations could be utilized if desired.
As illustrated in FIG. 3, the screen cleaning device 12 may be removed from the dedicated receiver 20 at any desired time and used to clean the viewing screen 24 of fingerprints dust and dirt as desired. This is done by simply wiping the cleaning pad 16 over the viewing screen 24 (note action arrows).
Reference is now made to FIG. 3 illustrating yet another alternative embodiment of screen cleaning device 32. The screen cleaning device 32 includes a body 34 having a reservoir 36 holding cleaning fluid 38. A metering device 40 meters cleaning fluid 38 from the reservoir 36 to the wet cleaning pad 42. In the illustrated embodiment, the metering device 40 comprises a disk including a series of small fluid feeding apertures 46 that function to feed cleaning fluid 38 to the cleaning pad 42 by capillary action.
The screen cleaning device 32 further includes a handle 48 and a dry pad 50 held in a compartment 52 beneath a removable cap 54.
In use, an individual removes the cleaning device 32 from the receiver or well 56 held in an interior trim component 58 of the vehicle. The individual may then use the wet cleaning pad 42 to clean fingerprints and dust from the viewing screen 24. Afterwards or in the alternative, the individual may remove the cap 54 and sweep the viewing screen 24 with the dry pad 50 to complete the cleaning of the viewing screen.
Many high-end motor vehicles today include a body control module 60. As illustrated in FIG. 4, such a body control module 60 may comprise a computing device having one or more processors 68, one or more memories 70, one or more interfaces 72, a human interface 74, a GPS/geo locator component 76, a display device such as a multi-function display with touchscreen capability 78 and a speech processor 80 that all communicate with each other over communication bus 82. The body control module 60 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 body control module 60 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 body control module 60 is connected by communication bus (not shown) to other control modules that provide one or more of these additional functions.
Where the viewing screen 24 is a touchscreen, cleaning of the screen may inadvertently change vehicle operating settings such as radio stations, entertainment system volume, climate control settings and the like that are accessed and controlled through the touchscreen.
In order to avoid this problem, the screen cleaning system 10 further includes a cleaning mode wherein all screen settings are frozen so that no setting is changed inadvertently during screen cleaning. In one possible embodiment, the cleaning mode is activated by contacting the touchscreen 24/78 at an image indicating the cleaning mode function. In another possible embodiment a separate actuator or switch 82 is provided on the center stack 22 to activate and deactivate cleaning mode. See FIG. 2b. In yet another possible embodiment illustrated in FIG. 3, an actuator switch 83 is associated with the receiver 20 or well 56 so that when the screen cleaning device 12 or 32 is removed from the receiver, cleaning mode is activated. In contrast, when the screen cleaning device 12 or 32 is held in the receiver 20 or well 56, cleaning mode is deactivated. That switch 83 may comprise, for example, a microswitch, a capacitive sensor or the like.
In one possible embodiment, when cleaning mode is active, that activation is indicated by a message presented on the touchscreen. In another possible embodiment, when cleaning mode is activated, the indication is provided by a separate indicator such as an illuminated bezel 84 around the receiver 56 (see FIG. 3) or an illuminated bezel 86 around the screen 24 to be cleaned (see FIG. 2a). Not only does the illumination of the bezel 84 or 86 alert the driver to the fact that the cleaning device 12 or 32 has been removed from the receiver 20 or well 56, it also aids in preventing the cleaning device from being misplaced or lost. In yet another possible embodiment, the bezel 84 could be illuminated one color, such as green, when the cleaning device 32 is in the receiver 56 and illuminated a different color, such as red, when the cleaning device is removed from the receiver.
In another possible embodiment, when cleaning mode is activated, the screen is a solid color particularly suited to help an individual see and clean finger prints and dust from the viewing screen 24. A blank or black screen are two possibilities.
In summary, the screen cleaning system 10 provides a number of benefits. The system ensures that the screen cleaning device 12 or 32 is readily available at all times to clean a viewing screen 24 of fingerprints and dust whenever needed. Further, the cleaning device 12, 32 is secured in a dedicated receiver 20 or well 56 integrated into the interior trim of the motor vehicle when not in use. There the cleaning device 12, 32 remains readily assessable to an individual at all times for user convenience. Further, the system 10 eliminates cluttering a glove box, console storage compartment or door pockets with screen cleaning utensils. Significantly, the cleaning device 12, 32, when held securely in the receiver 20, 56, will not produce an annoying vibration or rattle.
The cleaning pads 16, 42 or 50 of the screen cleaning device 12 or 32 may be replaced and the cleaning fluid reservoir 36 may be recharged with cleaning fluid 38 in some embodiments. In others, the entire screen cleaning device 12 or 32 is simply replaced as necessary due to pad wear or use of all the cleaning fluid.
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. For example, while FIGS. 2a and 2b illustrate an embodiment wherein the cleaning device 12 is held in a receiver 20 provided on the center stack 22, it should be appreciated that other trim locations are possible. For example, the well 56 is held in the trim component 58 which may comprise the center console, the center console storage compartment, the instrument panel, the glove box or other conveniently located position in the motor vehicle. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
