Vehicle intersection monitoring system and method
First Claim
1. A vehicle intersection monitoring method comprising:
- generating host vehicle information with a navigation unit, the host vehicle information including a host vehicle location, a host vehicle heading, and information indicating a host vehicle intended next maneuver;
receiving remote vehicle information with a receiver, the remote vehicle information including a remote vehicle location, a remote vehicle heading, and information indicating a remote vehicle intended next maneuver;
determining an intersection location with a controller based on the host vehicle heading and the remote vehicle heading;
selecting with the controller an intersection scenario from a plurality of intersection scenarios stored in a storage unit, based on the host vehicle information and the remote vehicle information;
determining with the controller a location relationship between the host vehicle location and the remote vehicle location, the location relationship including a straight line between the host vehicle location and the remote vehicle location, and an angle between a travel path of the host vehicle and the straight line based on a fixed coordinate system and a preselected angle direction; and
monitoring, with the controller, the location relationship between the host vehicle location and the remote vehicle location according to an algorithm that is determined based on the selected intersection scenario.

Abstract
A vehicle intersection monitoring method includes exchanging host vehicle information and remote vehicle information between a host vehicle and a remote vehicle, with the host vehicle information including information pertaining to a host vehicle location, a host vehicle heading and a host vehicle intended next maneuver and the remote vehicle information including information pertaining to a remote vehicle location, a remote vehicle heading and a remote vehicle intended next maneuver. The method further includes identifying a road intersection relating to the host vehicle heading and the remote vehicle heading, selecting an intersection scenario from a plurality of intersection scenarios based on the host vehicle information and the remote vehicle information, and monitoring, by operation of a processor, a location relationship between the host vehicle and the remote vehicle according to an algorithm that is determined based on the selected intersection scenario.
