Abstract

The present invention is a system for use, for example, in motorized vehicles to provide a warning signal directed to the attention of the driver of the equipped vehicle and also to the operator of a target vehicle, as well as possibly other drivers in the vicinity of the system-equipped vehicle of impending danger. The system senses the presence of obstacles that can be identified by scanning and subsequently tracked. Obstacles may be fixed objects or other vehicles either also moving or still. The system detects and determines the distance separating the object from the sensor location, its ground velocity and rate of closure. The system'"'"'s signaling sound and light emitters are able to be positioned and adjustable to face a target receiver and are able to signal with varying sound and light patterns and output amplitudes.

Claims
