REAR COLLISION WARNING ALERT SYSTEM AND METHOD
First Claim
1. A method of generating a warning of a rear collision, comprising:
- setting, by a controller, a concern area around a vehicle;
measuring, by a sensor, a position and a distance of an approaching object;
storing, by the controller, the position and distance of the approaching object and determining whether the path of the approaching object crosses the boundary of the concern area, using at least two or more stored positions and distances;
calculating, by the controller, a time-to-collision of the approaching object, when the path of the approaching object crosses the boundary of the concern area; and
generating, by the controller, a warning indicating the approaching object.

Abstract
A system and method of generating a warning of a rear collision that includes setting, by a controller, a concern area around a vehicle and measuring, by a sensor, the position and distance of an approaching object. In addition, the controller is configured to store the position and distance of the approaching object and determine whether the path of the approaching object crosses the boundary of the concern area, using at least two or more stored positions and distances. The controller calculates a time-to-collision of the approaching object, when the path of the approaching object crosses the boundary of the concern area; and generates a warning which indicating the approaching object.

6. A system that generates a warning of a rear collision, comprising:
-
a sensor configured to measure the position and distance of an approaching object; and a controller configured to; set a concern area around a vehicle; store the position and distance of the approaching object and determining whether the path of the approaching object crosses the boundary of the concern area, using at least two or more stored positions and distances; calculate a time-to-collision of the approaching object, when the path of the approaching object crosses the boundary of the concern area; and generate a warning indicating the approaching object. - View Dependent Claims (7, 8, 9, 10)

11. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:
-
program instructions that set a concern area around a vehicle; program instructions that control a sensor to measure a position and a distance of an approaching object; program instructions that store the position and distance of the approaching object and determining whether the path of the approaching object crosses the boundary of the concern area, using at least two or more stored positions and distances; program instructions that calculate a time-to-collision of the approaching object, when the path of the approaching object crosses the boundary of the concern area; and program instructions that generate a warning indicating the approaching object. - View Dependent Claims (12, 13, 14, 15)
