DETAILED DESCRIPTION

[0023] Reference is now made to FIGS. 1-5 illustrating the new and improved motor vehicle display 10. That motor vehicle display 10 includes a display screen 12 having a first end 14 adjacent a first A-pillar 16 and a second end 18 adjacent a second A-pillar 20 of the motor vehicle 22. As illustrated in FIG. 1, the display screen 12 may extend fully across the bottom or base portion of the windshield 24 and the top of the instrument panel 26 the full width across the motor vehicle from the first A-pillar 16 to the second A-pillar 20. In such an embodiment, the two A-pillars 16, 20 may provide structural support for the display screen 12. In alternative embodiments, the display screen 12 may extend to within approximately ten, seven, five or three centimeters of the first A-pillar 16 and the second A-pillar 20 with the small space between the first end 14 of the display screen 12 and the first A-pillar 16 and the small space between the second end 18 of the display screen and the second A-pillar filled by a decorative closeout trim panel or a structural support feature.

[0024] As best illustrated in FIGS. 2-4, the display screen 12 has a display side 28 directed away from the windshield 24 toward the occupants of the motor vehicle 22 and adapted to display an image for viewing. In addition, the display screen 12 includes a back side 30 oriented motor vehicle forward toward the windshield 24 and opposite the display side 28. A plurality of external ribs 32 support the display screen 12 along the back side 30. As best illustrated in FIGS. 3 and 4, the plurality of external ribs 32 are configured as airflow vanes and are adapted to direct airflow from an HVAC system of the motor vehicle and, more particularly from the defrost register outlet 34 between the display screen 12 and the windshield 24 of the motor vehicle. Note action arrows A showing the airstream passing through the gap G maintained at the top of the display screen 12 between the display screen and the windshield 24.

[0025] As should also be appreciated from reviewing FIG. 4, a blackout 36 may be provided along the bottom portion of the windshield 24 in order to conceal the back side 30 of the display screen 12 and the external ribs 32 from view. This improves the aesthetic appearance of the motor vehicle when viewed from the front or front quarter of the motor vehicle.

[0026] As illustrated in FIG. 5, the motor vehicle display 10 may also include a controller 38 operatively connected to the display screen 12 and configured to control the display of information on the display screen. That controller 38 may comprise a computing device such as a dedicated microprocessor or an electronic control unit (ECU) operating in accordance with instructions from appropriate control software. Thus, the controller 38 may comprise one or more processors, one or more memories and one or more network interfaces all in communication with each other over a communication bus.

[0027] In some embodiments the controller 38 may comprise a body control module or BCM having one or more processors, one or more memories, one or more network interfaces, a human interface, a GPS/Geo Locator component, and a speech processor that all communicate with each other over a communication bus. As is known in the art, a body control module or BCM 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 or BCM 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 or BCM may be connected by a communication bus (not shown) to other control modules that provide one or more of these additional functions. Advantageously, the speech processor would allow the controller 38 to respond to voice commands from the motor vehicle operator or other occupants of the motor vehicle if desired.

[0028] As further illustrated in FIG. 5, the motor vehicle display 10 may also include a first rearview side camera 40 and a second rearview side camera 42 connected to the controller 38. More specifically, the first rearview side camera 40 would provide a rearview commonly associated with an exterior driver's side rearview mirror while the second rearview side camera 42 would provide a rearview commonly associated with an external passenger side rearview mirror.

[0029] In some embodiments or applications, the controller 38 may be configured to display a first image I.sub.1 from the first rearview side camera 40 on the display side 28 of the display screen 12 adjacent the first end 14 and first A-pillar 16. See FIG. 2. Similarly, the controller 38 may also be configured to display a second image I.sub.2 from the second rearview side camera 42 on the display side 28 of the display screen 12 at the second end 18 adjacent the second A-pillar 20. In such an embodiment, actual driver's side and passenger side exterior rearview mirrors may be omitted from the motor vehicle to improve the aesthetic appearance and aerodynamic performance of the motor vehicle while at the same time providing the necessary rearview images to allow safe operation of the motor vehicle. Here it should be noted that the first image I.sub.1 and second image I.sub.2 are located at positions where a driver is conditioned to find them: that is near where the exterior rearview mirrors would normally be located.

[0030] The display screen 12 may comprise a single display extending all the way across the motor vehicle 22 at the base of the windshield 24 along the top of the instrument panel 26 or a plurality of displays that are configured together to form a continuous display screen extending from the first A-pillar 16 to the second A-pillar 20. In one possible embodiment, the display screen 12 is a liquid crystal display. It should be appreciated, however, that the display screen 12 may comprise other known technologies or even technologies to be developed in the future which are suitable for the intended purpose. Thus, the display screen 12 may be an organic light emitting diode (OLED) based display, a light emitting diode (LED) based display or a plasma display panel (PDP).

[0031] Consistent with the above description, a method is provided of displaying information in a motor vehicle 22. That method may be broadly described as comprising the steps of locating the display screen 12 across the top of the instrument panel 26 and along the bottom portion of the windshield 24 so that the display screen extends from adjacent the first A-pillar 16 to adjacent the second A-pillar 20.

[0032] The method may also include the step of displaying, by the controller 38, the first image I.sub.1 from the first rearview side camera 40 on the display screen 12 adjacent the first A-pillar 16. Similarly, the method may include the step of displaying, by the controller 38, the second image I.sub.2 from the second rearview side camera 42 on the display screen 12 adjacent the second A-pillar 20.

[0033] In addition, the method may include the step of displaying, by the controller 38, information from a wireless data network, such as the internet, on the display screen 12. Data or information from substantially any other computing device, such as a smart phone, a lap top computer or a tablet computing device may also be displayed on the display screen 12. Still further the method may include the step of displaying, by the controller 38, operating parameters of the motor vehicle on the display screen 12. Those operating parameters may include but are not necessarily limited to the speed of the motor vehicle, the revolutions per minute of the engine of the motor vehicle, the mileage of the motor vehicle, the oil pressure of the motor vehicle, the fuel level of the motor vehicle, the oil temperature of the motor vehicle, the coolant temperature of the motor vehicle, the operating status of the HVAC system of the motor vehicle, the operating status of the transmission of the motor vehicle, the operating status of the turn indicators of the motor vehicle, one or more warning lights respecting operating conditions of the motor vehicle and the like.

[0034] In addition, the method may include displaying, by the controller 38, other information of interest to the motor vehicle operator including, for example, navigation system data, directions to a desired location, the remaining travel range of the motor vehicle, telephone numbers, wireless messages, video or other streaming data or the like.

[0035] Still further, the method may include the step of directing conditioned air from the HVAC system of the motor vehicle 22 across the windshield 24 by means of a plurality of external ribs 32 that support the display screen 12 and are configured as airflow vanes. This is illustrated by the action arrows A in FIG. 4.

[0036] Further, the method may include the step of closing out the back side 30 and the external ribs 32 by providing the blackout 36 along the bottom portion or base of the windshield 24. See FIG. 4.

[0037] Still further, the method may include the step of maintaining a good sight line above the display screen 12 through the windshield 24 wherein that sight line meets down vision requirements for safely and efficiently operating the motor vehicle 22.

[0038] 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, the motor vehicle display 10 may further include a third rearview center camera 48 configured to provide a livestream video image consistent with the view commonly associated with the interior rearview mirror of a motor vehicle. The controller 38 may be further configured to display this third image I.sub.3 from the third rearview center camera 48 at the center of the display screen 12 where a driver is conditioned to find such a rearview image. See FIG. 1. In such an embodiment, the interior rearview mirror 44 may be removed from a motor vehicle in order to provide a more aesthetically pleasing and uncluttered interior along the windshield 24.

[0039] The controller 38 may also be configured to display a fourth image (not shown) from a fourth forward center camera 50 configured to provide a livestream video image forward of the motor vehicle. Further, the controller 38 may be connected with a series of video cameras configured to provide a 360 view around the motor vehicle for display on the display screen. Such a view is particularly beneficial when parking the motor vehicle in a tight area. 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.
