Vehicle pedestrian safety system and methods of use and manufacture thereof
First Claim
1. A vehicle control system for use with:
- a vehicle communications network, at least one source of pedestrian data relevant to at least one pedestrian'"'"'s location, and at least one source of vehicle system data relevant to the vehicle'"'"'s location and movement, the control system, comprising;
a processor that is configured to;
access the pedestrian data and the vehicle system data, determine a vehicle'"'"'s current location and speed based on the vehicle system data, build a predetermined number of vehicle polygons hardcoded into an application for representing a predicted path of the vehicle, build at least one pedestrian polygon representing a predicted path for at least one pedestrian detected in pedestrian data, classify each pedestrian detected in the pedestrian data as either at a left position or a right position relative to a centerline of the predicted path of the vehicle, define a plurality of warning zones based on the vehicle polygons, each warning zone defined by one or more vehicle polygons within the predicted path of the vehicle with a different level of warning based on a distance of each vehicle polygon from the vehicle, determine if one or more of the pedestrian polygons intersects at least one of the predetermined number of hardcoded vehicle polygons, and actuate a warning to a vehicle operator based on an intersection of the one or more pedestrian polygons with one or more of the vehicle polygons.

Abstract
The systems and methods are directed to a vehicle control system for use with: a vehicle communications network, at least one source of pedestrian data relevant to at least one pedestrian'"'"'s location, and at least one source of vehicle system data relevant to the vehicle'"'"'s location and movement. The control system can include a processor that is configured to determine a vehicle'"'"'s current location and speed based on the vehicle system data, build a predetermined number of vehicle polygons hardcoded into an application for representing a predicted path of the vehicle, build at least one pedestrian polygon representing a predicted path for at least one pedestrian detected in pedestrian data, and define a plurality of warning zones based on the vehicle polygons, and determine if one or more of the pedestrian polygons intersects at least one of the predetermined number of hardcoded vehicle polygons.
