Claim Text:
1. A vehicle intersection monitoring method comprising: generating host vehicle information with a navigation unit, the host vehicle information comprising a host vehicle location, and a host vehicle trajectory including a host vehicle heading and a host vehicle velocity; receiving remote vehicle information with a receiver, the remote vehicle information including a remote vehicle location, and a remote vehicle trajectory including a remote vehicle heading and a remote vehicle velocity; determining with a 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 the host vehicle heading and the straight line based on a fixed coordinate system and a preselected angle direction; determining with the controller whether the host vehicle and the remote vehicle are travelling on converging paths, including determining an expected intersection location, based on the location relationship; determining with the controller a host vehicle intent based on a current moving state of the host vehicle, the current moving state of the host vehicle including brake status of the host vehicle and whether the velocity of the host vehicle is below a threshold velocity; selecting with the controller a host vehicle response based on the host vehicle intent indicating an intent to approach the expected intersection location; providing no host vehicle response while the host vehicle brake status indicates a brakes released state and the velocity of the host vehicle is below the threshold velocity; and altering the host vehicle response, including determining with the controller whether the current moving state of the host vehicle has changed, determining with the controller an updated host vehicle intent based on the changed current moving state of the host vehicle, and altering with the controller the host vehicle response based on the updated host vehicle intent.
