摘要
A method involves calculating a closest point of approach (CPA) between a vehicle and a moving obstacle, determining the CPA is within a pre-determined distance from the vehicle at a point in time along the vehicle path, calculating a projected obstacle area (POA) for the moving obstacle, and modifying the vehicle path so the vehicle avoids the POA. The POA is a polygonal region between the boundaries calculated by determining a first point in time along the obstacle path that the moving obstacle is within the pre-determined distance, determining a second point in time along the obstacle path that the moving obstacle is within the pre-determined distance, creating a first line on one side of a midpoint line based upon a pre-determined angle of uncertainty, and creating a second line on the other side of the midpoint line based upon the pre-determined angle of uncertainty.
