Intersection assistance system and method
First Claim
1. An intersection assistance system comprising:
- at least one vehicle sensor configured to obtain vehicle information on vehicles approaching an intersection on a main roadway, wherein the intersection includes the main roadway crossing another roadway; and
a gap estimator configured to estimate gap information relating to a gap between the vehicles based on the vehicle information, the gap information including a length of the gap, a location of the gap, and a velocity of the gap.

Abstract
An intersection assistance system includes at least one vehicle sensor and a gap estimator. The vehicle sensor is configured to obtain vehicle information on vehicles approaching the intersection along a main roadway. The gap estimator is configured to estimate gap information relating to a gap between the vehicles based on the vehicle information. The gap information includes a length of the gap, a location of the gap, and a velocity of the gap. In a method of obtaining information for use in assisting a driver of an entering vehicle to safely enter an intersection, vehicle information is obtained on vehicles traveling toward the intersection on a main roadway. Next, gap information is estimated relating to a gap between the vehicles based on the vehicle information. The gap information includes a length of the gap, a location of the gap, and a velocity of the gap.

12. An intersection assistance system comprising:
-
at least one first vehicle sensor configured to obtain first lane vehicle information on vehicles approaching an intersection in a first lane of a road; a first gap estimator configured to estimate first lane gap information corresponding to a first lane gap between the vehicles traveling in the first lane based on the first lane vehicle information, the first lane gap information including a length of the first lane gap, a location of the first lane gap, and a velocity of the first lane gap; at least one second vehicle sensor configured to obtain second lane vehicle information on vehicles approaching the intersection in a second lane of the road; and a second gap estimator configured to estimate second lane gap information corresponding to a second lane gap between the vehicles traveling in the second lane based on the second lane vehicle information, the second lane gap information including a length of the second lane gap, a location of the second lane gap, and a velocity of the second lane gap. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

37. An intersection assistance system comprising:
-
at least one first vehicle sensor configured to obtain first lane vehicle information on vehicles approaching an intersection in a first lane of a road; a first gap estimator configured to estimate first lane gap information corresponding to a first lane gap between the vehicles traveling in the first lane based on the first lane vehicle information, the first lane gap information including a length of the first lane gap, a location of the first lane gap, and a velocity of the first lane gap; at least one second vehicle sensor configured to obtain second lane vehicle information on vehicles approaching the intersection in a second lane of the road; a second gap estimator configured to estimate second lane gap information corresponding to a second lane gap between the vehicles traveling in the second lane based on the second lane vehicle information, the second lane gap information including a length of the second lane gap, a location of the second lane gap, and a velocity of the second lane gap; and an intersection state controller configured to generate a state output based on at least one of the first lane gap information and the second lane gap information, wherein the state output is indicative of whether an entering vehicle can safely perform an intersection entering operation, and wherein the intersection state controller is configured to calculate a first gap period corresponding to a time at which the first lane gap is at the intersection based on the first lane gap information, and a second gap period corresponding to a time at which the second lane gap is at the intersection based on the second lane gap information, and wherein the intersection state controller is further configured to calculate a gap overlaying period corresponding to a time during which the first and second lane gaps overlay each other at the intersection.
