ABSTRACT:
A continuous exterior perimeter monitoring system for collision avoidance by vehicles with exterior objects is provided utilizing microelectronic digital logic circuits and techniques to produce a visual three-digit numerical display, a discrete multi-color display and a multi-level sound warning system, indicating precise and range of distances of exterior objects from vehicles which could collide therewith within pre-selected distances. The time-to-distance circuits of the system are an integral part of the digital logic circuits that are utilized to ascertain distances and such circuits are in a compact electronic package adapted to and is readily installed and integrated into existing vehicles utilizing the existing wiring electrical power systems primarily as a retro-fitting process for vehicles or as an original installation.
