METHOD AND SYSTEM FOR COLLISION ASSESSMENT FOR VEHICLES
First Claim
Patent Images
1. A method for assessing a target proximate a vehicle, the method comprising the steps of:
- obtaining a location and a velocity of the target;
mapping the location and the velocity onto a polar coordinate system via a processor; and
determining a likelihood that the vehicle and the target will collide using the mapping.

Abstract
Methods and systems are provided for assessing a target proximate a vehicle. A location and a velocity of the target are obtained. The location and the velocity of the target are mapped onto a polar coordinate system via a processor. A likelihood that the vehicle and the target will collide is determined using the mapping.

9. A method for assessing a target proximate a vehicle, the method comprising the steps of:
-
identifying a location and a velocity of the target; identifying a turn center, a trajectory, and a turn radius of the vehicle; calculating a first estimated time value at which the target is expected to reach the trajectory using the location and the velocity; calculating a second estimated time value at which the vehicle will contact the target if the vehicle and the target were to collide using the turn center and the turn radius; and determining that a collision between the vehicle and the target is likely if the first estimated time value is less than or equal to the second estimated time value via a processor. - View Dependent Claims (10, 11)

12. A system for assessing a target proximate a vehicle, the system comprising:
-
a detection unit configured to provide information pertaining to a location and a velocity of the target; and a processor coupled to the detection unit and configured to; map the location and the velocity onto a polar coordinate system, generating a mapping; and determine a likelihood that the vehicle and the target will collide using the mapping. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
