Description

A REARVIEW MIRROR HAVING AN ELECTRONIC INSTRUMENT DISPLAY

Technical Field

This invention relates to a novel rearview mirror which incorporates into it all or most of the instrument readouts desired in automobiles, trucks, or other similar vehicles. Electronic components, such as microprocessors and LEDs, are mounted behind the usual mirror for the vehicle. Signals are displayed through unsilvered portions of the mirror.

Background Art

In Canadian Patent 1,063,695, Litman discloses a rearview mirror for a motor vehicle which incorporates repeater lamps connected to the direction indicator system for the vehicle. This arrangement provides greater encouragement for a driver to use the rearview mirror and direction indicators, thereby reducing automobile accidents. Litman also discloses means to prevent the repeater lamps from dazzling the driver in low levels of general light.

The Litman mirror is a safety advance which merely brushes the surface of available alterations to the interior of a vehicle. Traditionally, automotive instruments have been located in the dashboard about the steering column. The practice arose out of necessity for mounting instruments where they would be visible and rigidly attached. However, continued location in this area hinders safety. The instruments generally are outside the driver's peripheral vision. To see them, the driver must take his or her eyes off the road, at least for an instant. The Litman patent discloses that turn signal indicator lamps can be placed behind the mirror reflective surface. However, the patent does not teach the need for multiple conventional dashboard instrumentation at this more desirable eye level location. As highl ighted at pages 45-48 of the De cemb e r , 1980, edition of Radio-Electronics, electronics are quickly replacing mechanical and electromechanical instrumentation in a dashboard. Much more information is available in easily read displays, thanks to these advances. However, it is recognized that the displays are still located out of the driver's field of view. Hope lies with heads-up displays used in military jet aircraft. By moving the readouts to the rearview mirror, the desired result may easily be achieved today.

Disclosure of Invention

A novel feature of this invention is its incorpor- ation of an electronic instrument display for travel infor- mation, such as speed, mileage, or fuel, within a rearview mirror to bring the display into the peripheral vision of the driver while he or she looks straight ahead and to remove the clutter from about the steering column so that additional safety improvements can be made to the dashboar area. Preferably, the mirror contains all the essentia components for the several readouts commonly 'housed in the dashboard. Microprocessors are small enough today to fit within a mirror housing. Sensors about the vehicle need be the only devices outside the mirror. Alternatively, the mirror may have only the readout electronics, such as LED's, with the processing devices mounted elsewhere in the vehicle.

The mirror has a housing which is attachable to the vehicle, either to the frame or to the windshield. The housing holds a mirror and several instrument displays, such as odometers, speedometers, fuel gauges, systems warnings, and turn signal indicators. Preferably the readouts are placed behind unsilvered portions about the periphery of the mirror. A microprocessor preferably is mounted in the housing to process signals and to display the information on the readouts. Means for electrical communication run from the electronic components in the housing to the vehicle. For mirrors glued to the windshield, the means for communication include a plurality of wires encapsulated in a transparent film, such as Mylar, which is glued to the windshield also . Conventional wiring processors and sensors are found in the vehicle frame. The mirror may also have trip log function readouts or a common readout with switches for the various functions.

These and other novel features of the present invention will be apparent from the following description, which is given by way of example of a preferred embodiment.

Brief Description of the Drawings

Figure 1 is a schematic of a rearview mirror having an electronic instrument display.

Figure 2 is a partially sectional schematic similar to Figure 1 showing a microprocessor mounted behind the partially silvered mirror.

Best Mode for Carrying Out the Invention

Referring now to Fig. 1, a rearview mirror which incorporates the novel features of this invention is schematically shown. The mirror has a housing 10 which is attachable by suitable means 11 to the frame or windshield of the vehicle. Means for electrical communication 12 extend from the electrical components in the mirror to suitable wiring in the vehicle, which runs to the ordinary sensors for travel information. Preferably, this means 12 includes a plurality of connecting wires of small diameter, arranged in ribbon form and encapsulated in a transparent plastic film (as shown in Fig. 2). Mounted in the housing 10 is a mirror 13 which has unsilvered portions. Signal lights, repeater lamps, or LEDs mounted behind the unsilvered portions emit light which is visible through the mirror 13. Preferably, these unsilvered portions are arranged about the periphery of the mirror 13 so that they do not impair its ordinary function. Alternately, the readouts may be placed around the housing of the mirror or on the glass of the mirror. As an example of the display possible. Fig. shows a digital speedometer 14 in the lower lefthand corner, an electronic fuel gauge 15 in the upper lefthand corner, digital odometer 16 in the upper center, systems warning lights 17, such as battery, oil, brakes, or seatbelts, along the right edge, and a digital readout 18 in the lower center. Arrayed along the bottom of the mirror are separately identified push-button switches 19 controlling a micropro- cessor 20 (Fig. 2) to permit display of various "trip log" functions in the readout 18. Preferably, the switches are lighted so that they are identifiable at night. The odometer 16, speedometer 14, and fuel gauge 15 may have individual microprocessors if space permits, or all of the readouts in the mirror may share one microprocessor 20 (Fig. 2). The intensity of light from the displays is controlled with a screw dimmer switch 23. Furthermore, a turn signal indicator 21 and a hi-low beam indicator 22 may be placed at a convenient place in the mirror. The microprocessors might just as easily be placed elsewhere in the vehicle, with only the readout components, such as the LEDs, in the mirror.

The odometer 16 preferably features a permanent semiconductor memory capable of extended data retention even with power removed. Thus, if the battery fails, the accumulated mileage will not be lost.

Incorporated 'by reference as part of this description, M. B. Weinsteins's article entitled "Electronics your next car," Radio-Electronics, December, 1980, pp. 45-48, discusses the state of the art in electronic displays as well as the numerous options available. Especially relevant is the discussion of "trip log" functions, such as distance traveled, elapsed time, average speed, estimated time of arrival, and distance to destination.

The mirror may also incorporate a clock, if desired. The clock may be made a part of the "trip log" functions whereby display of the time would appear only on selection, or a separate digital readout may be included in the mirror. In some circumstances, microtransmitters and microreceivers may be used to communicate between the mirror's readouts and the vehicle's sensors. Medical technology has recently developed these small components, although their use should be avoided if interference causes the transmission to be garbled.

Those skilled in the art will recognize numerous modifications to the preferred embodiment shown and described. Therefore, this invention should not be limited unless limitation is necessary due to the prior art or the nature and spirit of the appended claims.
