System and method for implementing vehicle collision avoidance warning via sensor pulses

摘要

In some examples, a device or system is configured to create a narrow vertical pathway of detection that permits the enforcement of a fixed "exclusion zone" that is narrow and does not widen with range. An example system located on a vehicle includes at least two vertically separated antennas that receive radar reflection signals, a processor, and an output device. The processor receives the radar reflection signals received by the antennas, determines vertical position of any obstacles identified in the radar reflection signals and determines if the obstacles are within a predefined alert zone. The output device can output an alert if any obstacle is within the alert zone. The predefined alert zone may be related to a protruding portion of the vehicle.
