SYSTEM AND METHOD FOR IMPROVED TRAFFIC FLOW REPORTING USING SATELLITE DIGITAL AUDIO RADIO SERVICE (SDARS) AND VEHICLE COMMUNICATIONS, NAVIGATION AND TRACKING SYSTEM

摘要

Systems and methods are provided for improved traffic flow reporting (e.g., system bandwidth conservation and timely traffic flow updates) using in-vehicle devices, service hub, and communications system for transmitting aggregated traffic flow data to the vehicles. In-vehicle devices store data relating to monitored segments of roadways (e.g., segment identifiers or location codes and designated range(s) of speed), and send messages to the hub when current vehicle speed is not within a selected range designated for the current segment of roadway where the vehicle is located. The hub provides updated traffic flow data based on the messages to the communications system for transmission to the vehicles. Vehicles can be configured to send messages based on various criteria. One or more selected vehicles can be commanded to send a message to the hub. Vehicles can respond to location-specified content in broadcast data when they determined themselves to be in the specified location.

主权项

1. A computer-implemented method of providing vehicle telematics services comprising:
receiving, at a vehicle, information comprising location-specific content when it is broadcast to a plurality of vehicles, the vehicle being one of the plurality of vehicles; determining, at the vehicle, its current position data; determining, at the vehicle, whether the vehicle position is within the location specified by the broadcast information; and generating a response, at the vehicle, when the vehicle location is within the location specified by the broadcast information.
