Abstract:
1. A method for assessing a target proximate a vehicle, the method comprising the steps of: via a detection unit configured to provide information pertaining to the target; obtaining a location and a velocity of the target and via a processor coupled to the detection unit; mapping the location and the velocity onto a polar coordinate system, wherein a pole of the polar coordinate system comprises a turn center of the vehicle; calculating an estimated time value at which a path of the target is expected to reach a trajectory of the vehicle using the mapping of the location and the velocity onto the polar coordinate system; determining a likelihood that the vehicle and the target will collide using the mapping, based on the calculated estimated time value; determining a velocity component of the target along a radius from the turn center of the vehicle using the velocity; determining a closest portion of the trajectory relative to the target; and calculating a distance between the closest portion of the trajectory relative to the target and the location; wherein the estimated time value is calculated using the velocity component and the distance.
