Claim:
1. A vehicle headlight control method comprising: generating host vehicle information with a positioning system, the host vehicle information including a host vehicle location and a host vehicle trajectory; receiving remote vehicle information with a receiver, the remote vehicle information including a remote vehicle location and a remote vehicle trajectory; calculating a remote vehicle distance from the host vehicle location with a controller based on the remote vehicle information and the host vehicle information; determining with the controller whether the host vehicle trajectory and the remote vehicle trajectory are such that the remote vehicle will pass by the host vehicle within a predetermined distance and whether the remote vehicle distance is less than the predetermined distance; determining with the controller whether the host vehicle information and the remote vehicle information indicate a converging path or a diverging path based on the host vehicle trajectory and the remote vehicle trajectory by determining an absolute value of the difference between a heading angle of the host vehicle and an angle between a direction of the host vehicle and a straight line from the host vehicle to the remote vehicle; and automatically operating with the controller a headlight of the host vehicle in a first setting while the remote vehicle distance is determined to be less than the predetermined distance and only when the converging path is indicated.
