ON-BOARD VEHICLE WARNING SYSTEM AND VEHICLE DRIVER WARNING METHOD
First Claim
1. An on-board vehicle warning system comprising:
- a location detecting section configured to detect a geographic location of a host vehicle equipped with the on-board vehicle warning system, and a geographic location of a forthcoming intersection;
a regulation retrieving section configured to retrieve a jurisdiction based on the geographic location of the forthcoming intersection, the jurisdiction including local intersection regulation information containing information pertaining to a vehicle position with respect to an intersection boundary at the time of a particular phase transition of a traffic light device;
an incoming message receiving section configured to receive intersection status information of the forthcoming intersection containing a geographic location of a boundary of the forthcoming intersection and phase information including a current phase and a time to the particular phase transition of a traffic light device of the forthcoming intersection; and
a potential violation alerting section configured to estimate a future position at which the host vehicle will be with respect to the boundary of the forthcoming intersection at the time that the particular phase transition is going to occur to determine a potential violation.

Abstract
An on-board vehicle warning system includes a location detecting section, a regulation retrieving section, an incoming message receiving section and a potential violation alerting section. The location detecting section detects respective geographic locations of a vehicle and a forthcoming intersection. The regulation retrieving section retrieves, based on the intersection location, a jurisdiction including local intersection regulation information pertaining to a vehicle position with respect to an intersection boundary at the time of a particular phase transition of a traffic light. The incoming message receiving section receives intersection status information of the intersection containing a geographic location of the boundary and phase information including a current phase and a time to the phase transition of a traffic light of the intersection. The potential violation alerting section estimates a future position of the vehicle with respect to the boundary at the occurrence of the phase transition to determine a potential violation.

11. A vehicle driver warning method comprising:
-
detecting a geographic location of a host vehicle, and a geographic location of a forthcoming intersection; retrieving a jurisdiction including local intersection regulation information containing information pertaining to a vehicle position with respect to an intersection boundary at the time of a particular phase transition of a traffic light device at any traffic intersection governed by the jurisdiction; receiving intersection status information of the forthcoming intersection containing a geographic location of a boundary of the forthcoming intersection and phase information including a current phase and a time to the particular phase transition of a traffic light device that exists at the forthcoming intersection; and estimating a future position at which the host vehicle will be with respect to the boundary of the forthcoming intersection at the time that the particular phase transition is going to occur to determine whether a warning of a potential violation should be provided. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
