Intersection visibility determination device, vehicle with intersection visibility determination device, and method for determining intersection visibility
First Claim
1. A method for determining visibility at an intersection before a host vehicle, comprising:
- obtaining information regarding the intersection before the host vehicle, the information including a type and a traveling position of an intersecting object that is traveling on a road, which intersects with a road on which the host vehicle is present, and that is presumed to cross the intersection; and
setting, based on the information regarding the intersection, a visibility determination area at the intersection as viewed from the host vehicle; and
determining, based on the visibility determination area, a visibility parameter that indicates whether the visibility at the intersection as viewed from the host vehicle is good or poor.

Abstract
An intersection visibility determination device includes an ECU that determines visibility at an intersection. When a host vehicle approaches an intersection with a stop sign, the ECU calculates conflict points at which a trajectory vector of the host vehicle intersects with virtual trajectory vectors of intersecting objects, which are presumed to come from the right side and the left side of the intersection, respectively. The conflict points are calculated based on information on types and traveling positions of the intersecting objects. The ECU sets visibility determination areas at the intersection as viewed from the host vehicle based on the positions of the conflict points, the right-side and the left-side visibility target distances, and the current location of the host vehicle, and calculates, based on the visibility determination areas, visibility distances that are used as visibility parameters indicating whether the visibility at the intersection is good or poor.

3. An intersection visibility determination device that determines visibility at an intersection before a host vehicle, comprising:
-
an intersection information obtaining unit that obtains information regarding the intersection before the host vehicle, the information including a type and a traveling position of an intersecting object that is traveling on a road, which intersects with a road on which the host vehicle is present, and that is presumed to cross the intersection; and a visibility parameter determination unit that sets, based on the information regarding the intersection, a visibility determination area at the intersection as viewed from the host vehicle, and that determines, based on the visibility determination area, a visibility parameter that indicates whether the visibility at the intersection as viewed from the host vehicle is good or poor. - View Dependent Claims (4, 5, 6, 7)
