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 selectively retrieve a jurisdiction from a plurality of jurisdictions based on the geographic location of the forthcoming intersection, the jurisdiction including local intersection regulation information, the local intersection regulation information including 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 that is impermissible within at least the jurisdiction and is permissible within at least one other jurisdiction of the plurality of jurisdictions;
an incoming message receiving section configured to receive intersection status information of the forthcoming intersection with the intersection status information 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, the potential violation alerting section being further configured to estimate a required stopping distance and a reaction distance, and determine a first warning distance from the boundary of the traffic intersection based on the reaction distance and the required stopping distance when the estimated future position is determined to be impermissible according to the local intersection regulation, the potential violation alerting section being further configured to provide a first warning notification to a driver of the host vehicle when the host vehicle reaches the first warning distance.

Abstract
An on-board vehicle warning system includes a vehicle location detecting section, a traffic regulation retrieving section, an incoming message receiving section, a vehicle information detecting section, a potential violation alerting section. The traffic regulation retrieving section is configured to retrieve information relating to a local traffic regulation corresponding to the location of the host vehicle from traffic regulation data including traffic regulations relating to a plurality of jurisdictions. The potential violation alerting section is configured to determine a potential traffic violation based on the intersection information and the vehicle travel information, and to selectively produce a driver notification to a driver of the host vehicle based upon a determination of the potential traffic violation according to the local traffic regulation corresponding to the location of the host vehicle.

2. An on-board vehicle warning system comprising:
-
a vehicle location detecting section configured to detect a location of a host vehicle equipped with the on-board vehicle warning system; a regulation retrieving section configured to selectively retrieve local intersection regulation information relating to a local traffic intersection regulation, which includes information pertaining to a vehicle position in relation to a phase of a traffic light device at a traffic intersection that is impermissible within at least one jurisdiction and permissible within at least one other jurisdiction of a plurality of jurisdictions, based on a location of the traffic intersection; an incoming message receiving section configured to receive intersection status information of the traffic intersection that is in front of the host vehicle with the intersection status information containing at least phase information of the traffic light device, the intersection status information containing information relating to a width of the traffic intersection; a vehicle information detecting section configured to detect vehicle travel information; and a potential violation alerting section configured to determine whether a potential violation of the local traffic intersection regulation by the host vehicle is possible based on the local intersection regulation information, the location of the host vehicle, the intersection status information and the vehicle travel information, and to selectively produce a driver notification to a driver of the host vehicle based upon a determination that the potential violation is possible. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)

10. 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 from a plurality of jurisdictions based on the geographic location of the forthcoming intersection, the jurisdiction including local intersection regulation information, the local intersection regulation information including 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 that is impermissible within at least the jurisdiction and is permissible within at least one other jurisdiction of the plurality of jurisdictions; receiving intersection status information of the forthcoming intersection with the intersection status information 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 in the forthcoming intersection; 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, and estimating a required stopping distance and a reaction distance; determining a first warning distance from the boundary of the traffic intersection based on the reaction distance and the required stopping distance when the estimated future position is determined to be impermissible according to the local intersection regulation; and providing a first warning notification to a driver of the host vehicle when the host vehicle reaches the first warning distance. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
