Problems solved by technology

However, neither Takagi nor Lemelson provide responsive and timely information to vehicles.
Furthermore, Nahla is not scalable and is not adaptable to existing roadways because Nahla teaches path prediction based upon the speed and direction of a particular train along an established railway.

Embodiment Construction

[0017]Referring to the figures wherein like numerals indicate corresponding parts throughout the several views, a system 10 and method 12 for predicting vehicle collision is provided. With reference to FIG. 1, the system 10 includes onboard equipment 14 and roadside equipment 16, both directed towards gathering information required to predict the path of a detected object and a vehicle.

[0018]Specifically, the system 10 includes a system vehicle 18 equipped with onboard equipment 14. The onboard equipment 14 detects information which can be used to predict the path of a vehicle. For example the system vehicle 18 may be equipped with a camera 20 or a global positioning system 10. The system vehicle 18 may also be equipped with a velocity sensor 22 and / or acceleration sensor 24, a wheel sensor 26 to measure the angular orientation of the vehicle wheels. Such sensors and equipment are currently known and used in the art. It is anticipated that the system 10 may also transmit information...

Abstract

A system and method for detecting a collision is provided. The system includes a system vehicle equipped with onboard equipment directed towards gathering vehicle information necessary to predict the path of the vehicle, a roadside infrastructure having a plurality of roadside sensors selectively distributed throughout the infrastructure so as to detect objects and gather information about the detected objects necessary to predict the path of the detected objects. A path predicting circuit is in communication with the system vehicle and the roadside infrastructure. The path predicting circuit processes information from the system vehicle and roadside infrastructure to predict the path of the system vehicle and detected objects. The path predicting circuit is in communication with a path collision circuit and the predicted paths are mapped on the path collision circuit so as to determine if the system vehicle may possibly collide with a detected object.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of U.S. Provisional Patent Application Ser. No. 61 / 107,516 filed Oct. 22, 2008, which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a collision warning system. More particularly, the invention relates to a collision warning system utilizing a path predicting circuit which gathers information from a system vehicle and roadside infrastructure to predict the path of the system vehicle and objects and a path collision circuit which determines if there is a potential for collision between the two.BACKGROUND OF THE INVENTION[0003]Vehicle warning systems are known and used to help drivers identify potential collisions. Specifically, U.S. Pat. No. 6,472,978 to Takagi et al. discloses a system including a communication unit held by a pedestrian and a transmitter / receiver equipped on a vehicle. The communication unit and the transmitter / receiver are in communication...
