Abstract

A virtual image display management system using a head-up display that improves the ability of an operator of an automobile, or other equipment, to focus on primary functions, such as vehicle operation, while providing secondary information within the operator'"'"'s primary visual field without requiring the operator to refocus. The present virtual image display management system integrates one or more secondary function displays into one reconfigurable virtual image head-up display. Several secondary functions are displayed sequentially using analog/digital symbology, icon representation, alphanumeric text or static/motion picture format. The operator may select secondary functions to be monitored, the display format, and the data acquisition intervals. A reconfigurable virtual image display processor accommodates more sophisticated sensor and communication functionality without penalizing efficiency and safety of the operator'"'"'s primary functions. The present system integrates, interprets, selects and displays data derived from multiple sensors and communications systems at an optimum visual location within the operator'"'"'s primary field of view. By displaying data in this fashion, an operator can vigilantly perform critical system functions while being kept well-informed of vehicle performance data, communication data and other useful functions and information.

Claims

1. A virtual image display management system for use in a vehicle, said system comprising:

a display projector disposed in the vehicle;

an optical combiner disposed on the vehicle for displaying a virtual image projected by the display projector at a predetermined location within the field of view of an operator of the vehicle;

a monitoring system disposed in the vehicle for sensing data external to the vehicle that is to be displayed to the operator;

a data and communication system disposed in the vehicle for providing data that is to be displayed to the operator;

a display electronics unit coupled to the monitoring system, data and communication system and to the display projector for providing data to the projector for display thereby to the operator;

an external video source coupled to a video input of the display unit; and

selection means disposed in the display unit for alternatively selecting data derived from the video source and the display electronics unit for display to the operator.

2. The system of claim 1 wherein further comprising;

a vehicle performance monitoring transducer coupled to the display electronics unit.

3. The system of claim 1 which further comprises:

a transceiver system; and

a modem coupled between the transceiver system and the display electronics unit.

4. The system of claim 1 which further comprises a keyboard input device coupled to the display electronics unit for permitting data entry thereto.

5. The system of claim 1 which comprises:

a plurality of monitoring systems and data and communication systems disposed in the vehicle, each of which is coupled to the display electronics unit, and wherein the display electronics unit simultaneously displays data from multiple ones of the plurality of monitoring systems and data and communication systems.

6. The system of claim 1 wherein the display electronics unit comprises:

a plurality of data adapters for interfacing interface to the plurality of monitoring systems and data and communication systems;

a processor for processing data from the plurality of monitoring systems, data systems, and communication systems; and

a mode selection switch coupled between the plurality of data adapters and the processor for selectively coupling data from a selected one of the plurality of monitoring systems and data and communication systems to the processor.

7. The system of claim 1 wherein the optical combiner comprises an aspheric combiner.

8. The system of claim 1 wherein the optical combiner comprises a spherical combiner.

9. The system of claim 1 wherein the optical combiner comprises an aspheric visor.

10. The system of claim 1 wherein the optical combiner comprises a spherical visor.

11. The system of claim 1 wherein the display electronics unit comprises:

a plurality of data adapter for interfacing to the plurality of monitoring systems and data and communication systems;

a processor for processing data from the plurality of monitoring systems, data systems, and communication systems; and

a voice recognition device coupled to the processor for selectively coupling data from a selected one of the plurality of monitoring systems and data and communication systems to the processor in response to predetermined voice commands issued by the operator.

12. The system of claim 1 wherein the display projector is disposed within a dashboard of the vehicle and wherein the optical combiner is comprised of a windshield of the vehicle.

13. The system of claim 1 wherein the display projector is disposed on top of a dashboard of the vehicle and wherein the optical combiner is comprised of a windshield of the vehicle.
