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 comprising a host vehicle location, a host vehicle trajectory including a host vehicle heading and a host vehicle velocity, and host vehicle component information including a host vehicle brake status;
receiving remote vehicle information with a receiver, the remote vehicle information comprising a remote vehicle location, a remote vehicle trajectory including a remote vehicle heading and a remote vehicle velocity, and remote vehicle component information including a remote vehicle brake status;
determining with a controller an expected host vehicle travel path based on the host vehicle information, an expected remote vehicle travel path based on the remote vehicle information, and an expected intersection location based on the expected host vehicle travel path and the expected remote vehicle travel path;
selecting with the controller an intersection scenario, from a plurality of intersection scenarios stored in a storage unit, based on the expected host vehicle travel path and the expected remote vehicle travel path;
determining with the controller a host vehicle intent to approach the expected intersection location based on the host vehicle trajectory and the host vehicle brake status;
determining with the controller a remote vehicle intent to approach the expected intersection location based on the remote vehicle trajectory and the remote vehicle brake status; and
selecting with the controller a host vehicle response corresponding to the intersection scenario, the determined host vehicle intent, and the determined remote vehicle intent, the host vehicle response including performing an intervening threat mitigation operation or refraining from performing an operation.

Abstract
A vehicle intersection monitoring method includes exchanging host vehicle information and remote vehicle information between a host vehicle and a remote vehicle, identifying a road intersection based on at least one of the host vehicle information and the remote vehicle information, and selecting an intersection scenario from a plurality of intersection scenarios based on the host vehicle information and the remote vehicle information. The method further includes 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, to determine whether a possibility of contact between the host vehicle and the remote vehicle exists proximate to the intersection, and performing a threat mitigation operation while the possibility of contact exists.
