Abstract

A sensor responsive display device includes a common display section for displaying various messages and/or warnings for a given period of time, and plural individual display sections, each corresponding to one of the messages and/or warnings displayed in the common display section.

Claims

1. An automotive vehicle display device for displaying various information according to vehicle driving conditions, comprising:

detector means for detecting driving and/or driver conditions for deriving plural detector signals in response to preselected vehicle driving and/or driver conditions being detected;

a common display for displaying various visual patterns, each corresponding to one of the conditions to be displayed, said common display including a storage for storing said display patterns;

a plurality of individual displays, each displaying one of said display patterns indicative of a corresponding one of said conditions; and

a display controller associated with said common and individual displays for controlling displays thereon, said common display, and one of the display patterns corresponding to the detected notable condition for a predetermined period of time; and

said controller operating one of said individual displays to display specific information concerning said notable condition in response to said detector signal as long as the preselected vehicle driving condition is maintained.

2. The display device as set forth in claim 1, wherein said common display comprises a plurality of superimposed transparent plates, each of which has a display image corresponding to one of said conditions, and a plurality of light sources, each of which is adapted to emit light through one of said plates to illuminate the display image in the corresponding plate.

3. The device as set forth in claim 1 or 2, wherein said common display has a display area greater than that of each of said individual displays, said display area of said common display being large enough to be noticeable and legible.

4. The device as set forth in claim 3, wherein said common display includes:

a digital clock, and means for displaying a time indication of the digital clock on the common display while other messages of the common display are not being displayed.

5. A display device applicable for an automotive vehicle to display driving messages and/or warnings, comprising:

a plurality of first superimposed transparent members each of which is formed with a plurality of apertures which in combination constitute an image representative of information to be displayed;

first light sources, each of which is positioned to emit light through one of said transparent members, each of said light sources being responsive to the occurrence of one of preselected vehicle driving conditions and remaining on for a given period of time when activated;

a plurality of second transparent members, each of which has an image corresponding to one of the images of said first transparent members, the images of the second transparent members being mutually spaced from each other; and

second light sources, each of which is positioned to emit light through one of said second transparent members and is adapted to emit light as long as the corresponding notable condition persists.

6. A display device as set forth in claim 5, wherein each of said first light sources is associated with a time setting circuit which defines said given period for which said first light sources remain on.

7. A display device as set forth in claim 5, wherein said first transparent members comprises a common display including a digital clock system, said first light sources being associated with said digital clock system so that an image derived from said digital clock system is normally applied to said common display and is decoupled from said common display while any of first light sources emits light.

8. A display device as set forth in claim 5, wherein said first light sources are interrelated so that a previously-activated light source responsive to one notable condition is deactivated in response to any other of said notable conditions being derived.

9. A system for visually signalling vehicle drivers comprising sensor means for deriving a plurality of information signals, a display including a common display area and plural individual display areas, one individual display area being provided for each of the signals, each individual display area including means for providing a different image in a different space to the driver for each signal, the common display area including means for providing a different image in the same space to the driver for each signal, and means responsive to the signals for activating the common display area and one of the individual display areas so that the individual display area associated with one of said signals provides the driver with an image indicative of the information associated with said one signal after the image indicative of the information associated with said one signal is no longer provided to the driver by the common display.

10. The system of claim 9 wherein the means for activating includes means for enabling the common display to provide the driver with the information associated with said one signal for only a predetermined interval.

11. The system of claim 10 wherein the means for activating includes means for enabling each individual display to provide the driver with the information associated with said one signal for a predetermined duration that overlaps with and extends considerably beyond the predetermined interval.

12. The system of claim 10 further including a clock source, means for normally coupling a time indication image derived in response to the clock source to the common display area and for replacing the time indication on the common display with the information associated with said one signal for the predetermined interval in response to said one signal being derived.

13. The system of claim 9 wherein the means for activating includes means responsive to derivation of a second of said signals for replacing the information associated with said one signal on the common display with information associated with the second of the signals without affecting the displayed information associated with said first signal on the individual display area provided for the first signal.

14. The system of claim 9 wherein the common display area includes plural superimposed fixed image representations, one for the information in each signal, an optical arrangement for separately illuminating each fixed image representation, the optical arrangement for each fixed image representation responsive to one of the signals so that the fixed image representation associated with the information of each signal is provided to the driver in response to derivation of the associated signal.

15. The system of claim 14 wherein each image representation is formed on a different translucent member, and the optical arrangement includes a different light source positioned at an edge of each translucent member for transmitting light through the member and causing the image on the member to be projected to the driver.

16. The system of claim 9 wherein the means for activating includes means for enabling plural individual areas to simultaneously provide the driver with images of the information associated with a plurality of said signals.
