Vehicle pedestrian safety system and methods of use and manufacture thereof
First Claim
1. A vehicle control system to enhance pedestrian safety, comprising:
- a memory storing instructions when executed by a processor cause the processor to;
access pedestrian data and vehicle system data;
determine a current location and a speed of a vehicle based on the vehicle system data;
build at least one vehicle polygon 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;
define a plurality of warning zones based on the at least one vehicle polygon, wherein at least one warning zone of the plurality of warning zones is defined with a different level of warning based on a distance of the at least one vehicle polygon with respect to the vehicle;
determine if the at least one pedestrian polygon intersects the at least one vehicle polygon; and
actuate a warning to a vehicle operator based on an intersection of the at least one pedestrian polygon and the at least one vehicle polygon.

Abstract
A system and method to enhance pedestrian safety that include accessing pedestrian data and vehicle system data and determining a current location and a speed of a vehicle based on the vehicle system data. The system and method also include determining a current location and a speed of a pedestrian based on the pedestrian data and building at least one vehicle polygon that represents a predicted path of the vehicle. The system and method additionally include building at least one pedestrian polygon that represents a predicted path of the pedestrian. The system and method further include determining if the at least one pedestrian polygon intersects the at least one vehicle polygon and actuating a warning based on an intersection of the at least one pedestrian polygon with the at least one vehicle polygon.
