1. A method of monitoring vehicle movement for use in a first vehicle, the method comprising the steps of:
- determining a lane location of the first vehicle at a first point in time;
determining a position of a second vehicle at a second point in time, the second point in time being subsequent to the first point in time;
determining additional lane locations of the first vehicle at a plurality of additional points in time, each of the additional points comprising a different intermediate point in time that is subsequent to the first point in time and prior to the second point in time;
determining additional positions of the second vehicle at the intermediate points in time; and
determining, via a processor, a path of the second vehicle based at least in part on the position of the second vehicle at the second point in time, the additional positions of the second vehicle at the intermediate points in time, the lane location of the first vehicle at the first point in time, and the additional lane locations of the first vehicle at the intermediate points in time, for use in evaluating possible intersection of paths between the first and second vehicles,wherein determining a position of the second vehicle comprises correlating prior lane locations of the first vehicle with subsequent positions of the second vehicle, to ascertain a relationship between a current position of the second vehicle and a current location of the lane with respect to the second vehicle.

Abstract
A method for monitoring vehicle movement for use in a first vehicle includes the steps of determining a lane location at a first point in time, determining a position of a second vehicle at a second point in time, the second point in time being subsequent to the first point in time, and determining a path of the second vehicle based at least in part on the position of the second vehicle and the lane location.

8. A system for monitoring vehicle movement for use in a first vehicle, the system comprising:
-
a first detection unit configured to at least facilitate obtaining a lane location of the first vehicle at a first point in time; a second detection unit configured to at least facilitate obtaining a position of a second vehicle at a second point in time, the second point in time being subsequent to the first point in time; wherein; the first detection unit is further configured to at least facilitate obtaining additional lane locations of the first vehicle at a plurality of additional points in time, each of the additional points comprising a different intermediate point in time that is subsequent to the first point in time and prior to the second point in time; and the second detection unit is further configured to at least facilitate obtaining additional positions of the second vehicle at the intermediate points in time; and a processor coupled to the first detection unit and the second detection unit and configured to at least facilitate determining a path of the second vehicle based at least in part on the position of the second vehicle at the second point in time, the additional positions of the second vehicle at the intermediate points in time, the lane location of the first vehicle at the first point in time, and the additional lane locations of the first vehicle at intermediate points in time, for use in evaluating possible intersection of paths between the first and second vehicles, wherein the processor is further configured to at least facilitate determining if the second vehicle is encroaching on the lane of the first vehicle, if the second vehicle is trailing the first vehicle, based at least in part on a lane position of the first vehicle as identified using a camera on the first vehicle and a current position of the second vehicle that is identified using a radar system on the first vehicle shortly after the identification of the lane position of the first vehicle by the camera. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of monitoring vehicle movement for use in a first vehicle, the method comprising the steps of:
-
determining a lane location of the first vehicle at a first point in time; determining a position of a second vehicle at a second point in time, the second point in time being subsequent to the first point in time; determining additional lane locations of the first vehicle at a plurality of additional points in time, each of the additional points comprising a different intermediate point in time that is subsequent to the first point in time and prior to the second point in time; determining additional positions of the second vehicle at the intermediate points in time; determining, via a processor, a path of the second vehicle based at least in part on the position of the second vehicle at the second point in time, the additional positions of the second vehicle at the intermediate points in time, the lane location of the first vehicle at the first point in time, and the additional lane locations of the first vehicle at the intermediate points in time, for use in evaluating possible intersection of paths between the first and second vehicles; and determining if the second vehicle is encroaching on the lane of the first vehicle, if the second vehicle is trailing the first vehicle, based at least in part on a lane position of the first vehicle as identified using a camera on the first vehicle and a current position of the second vehicle that is identified using a radar system on the first vehicle shortly after the identification of the lane position of the first vehicle by the camera.
