The support and advice of Robert Nicholson, chief of that office, is gratefully acknowledged. High-technology displays and controls are having a substantial impact on the driving environment and, in the future, this impact will increase because of advances in electronics and computers as well as cost advantages. This report reviews the status of these displays and controls and the concerns that may be raised in their relation to the driving task.

The report describes the need to integrate this technology into the driving environment, thereby enhancing safety, convenience and comfort without degrading or distracting from the primary driving tasks. Automotive manufacturers are beginning to develop methodologies for evaluating the impact of these new technologies on safety, but at present no single methodology exists. This report outlines the requirements for such a methodology. New display technology utilizes electronic graphic displays to replace, expand, and augment more traditional analog displays. The advances in microprocessor technology and related cost advantages have fostered a new era in displays and controls. The Japanese car manufacturers have made the greatest use of the technology in this field with the European manufacturers adhering to the more traditional type of display/control systems. The U.S. manufacturers occupy a middle position. Four main types of display technologies are available, vacuum fluorescent, liquid crystal, light-emitting diodes, and cathode-ray tubes. The advantages and disadvantages of each type regarding resolution, brightness, color, cost, and other features are described in the report. These display types are now used for instrument clusters (speedometer, tachometer, odometer, temperature, and fuel gauges), radios, clocks, trip function and driver information monitors. New vehicle diagnostic systems continuously monitor up to twenty vehicle functions and alert the driver through both visual and auditory warnings of an out-of-specification condition. A likely future trend in display systems is the use of the multi functional cathode-ray tube (CRT) type display for systems which provide detailed information. The 1986 Buick Riviera is an example of this application. The CRT can provide an interface for vehicle systems such as status, climate control, and audio entertainment systems, and also display maps required for navigations systems (i.e., Etak Navigator). A good indicator of the use of CRTs in the future is the extensive use of them in concept cars.
