Abstract

This article describes a system that utilizes the processing power on board a car to gather, retain and make available transportation information. In recent years microcomputers have established an essential role in automotive applications. Areas such as entertainment, comfort, convenience, instrument panel and transmission controls have assumed a growing importance in addition to the initial major application of engine controls. Considerable growth is expected in automotive electronics such that some future car modules will have ten to twenty microcomputers. Products such as satellite navigation systems, high quality displays, touch-sensitive panels, radio telephone voice and data communication, voice synthesis and recognition, and greatly improved theft-deterrent systems will be part of future automobiles.

Transportation Information Distribution System

This article describes a system that utilizes the processing power on board a car to gather, retain and make available transportation information. In recent years microcomputers have established an essential role in automotive applications. Areas such as entertainment, comfort, convenience, instrument panel and transmission controls have assumed a growing importance in addition to the initial major application of engine controls. Considerable growth is expected in automotive electronics such that some future car modules will have ten to twenty microcomputers. Products such as satellite navigation systems, high quality displays, touch-sensitive panels, radio telephone voice and data communication, voice synthesis and recognition, and greatly improved theft- deterrent systems will be part of future automobiles. This disclosure describes a product that utilizes the processing power on board the car to gather, retain, and make available transportation information. It provides a useful and desirable service while providing a means for eliminating congestion caused by a proliferation of signs and unattractive advertising billboards. The transportation information distribution system (TIDS), disclosed herein, is illustrated in block diagram form in Fig. 1 in a representative location. A low power, short range (2 miles), radio transmitter 1 is placed on the side of a highway at the outskirts of town. This transmitter operates in the 2 to 30 MHz band, above the AM broadcast range. Information transmitted about the town being approached may ...
