1. A method for a subject vehicle to avoid collisions, comprising:
- scanning at least one lane feeding into an intersection;
detecting the presence of a threat vehicle in the at least one lane;
predicting whether the subject vehicle and the threat vehicle will occupy the intersection at the same time;
issuing a warning in response to said predicting.

Abstract
A method for a subject vehicle to avoid collisions is provided. At least one lane feeding into an intersection is scanned. The presence of a threat vehicle in the at least one lane is detected. Whether the subject vehicle and the threat vehicle will occupy the intersection at the same time is predicted. A warning is issued in response to the predicting.

7. A method for a subject vehicle to avoid collisions, comprising:
-
separately scanning left, right, and forward sectors of the subject vehicle, said scanning being responsive to the subject vehicle coming within a predetermined distance of an intersection;
detecting the presence of a threat vehicle in at least one lane feeding the intersection;
predicting whether said subject vehicle and said threat vehicle will occupy the intersection at the same time;
issuing a warning in response to said predicting. - View Dependent Claims (8, 9, 10)

11. A method of controlling a radar antenna mounted on a moving vehicle, comprising:
-
oscillating the radar antenna about a predetermined angle relative to a control point, the control point representing a position in a lane feeding into an intersection; and
moving the control point away from the intersection as the subject vehicle approaches the intersection. - View Dependent Claims (12, 13, 14, 15, 18, 19, 20)

16. A method for preventing a subject vehicle from accidents in intersections, comprising:
-
storing a map in a database, the map including at least one intersection with a traffic control device;
receiving coordinate data reflecting a position of the subject vehicle;
determining whether the subject vehicle will enter an intersection of the at least one intersection in violation of an associated traffic control device;
issuing a warning to a driver of the subject vehicle in response to a determination that the subject vehicle will enter an intersection of the at least one intersection in violation of an associated traffic control device;
scanning an area around the intersection;
identifying any threat vehicles in the area;
predicting whether the subject vehicle and the threat vehicle will occupy the intersection at the same time;
issuing a warning to a driver of the subject vehicle in response to a prediction that the subject vehicle and the threat vehicle will occupy the intersection at the same time;
determining whether prevailing conditions indicate a low probability of a collision in the intersection; and
disabling said issuing a warning to a driver of the subject vehicle in response to a prediction when the prevailing conditions indicate a low probability of a collision in the intersection.

17. A collision prevention device mounted on a subject vehicle, comprising:
-
left, right and center radar antennas;
a controller programmed to oscillate said left and right radar antennas about a predetermined angle relative to left and right control points respectively, the control points representing positions in left and right lanes feeding into an intersection; and
said controller being programmed to move said left and right control points away from the intersection as the subject vehicle approaches the intersection.

21. A collision prevention device, comprising:
-
left, right and center radar antennas;
a map database, a map in the database including an intersection;
a tracker capable of distinguishing a threat vehicle approaching the intersection from other objects detected by said left, right, and center radar antennas;
a controller being capable of determining whether said subject vehicle and said threat vehicle will occupy an intersection at the same time; and
said controller being programmed to issue a warning signal in response to whether said subject vehicle and said threat vehicle will occupy an intersection at the same time and when the prevailing conditions do not indicate a low probability of a collision in the intersection. - View Dependent Claims (22, 23, 24)
