VEHICLE COMMUNICATIONS VIA WIRELESS ACCESS VEHICLE ENVIRONMENT
First Claim
1. A vehicle on-board-unit (OBU) comprising:
- at least one processor running at least one computer program configured to enable the OBU to (i) comply with IEEE 802.11p Wireless Access Vehicular Environment (WAVE) functionality, including the IEEE 1609 suite of specifications. and (ii) trilaterate position fixes based on the geo-location of roadside units (RSUs) from which it can receive periodic WAVE service advertisements and the variable signal strength indicated in said announcements.

Abstract
Vehicle Communications using IEEE 802.11p WAVE functionality includes structure and method whereby a smart phone (SP) linked to an On Board Unit (OBU) having WAVE functionality, and incorporating Automotive Telemetry Protocol (ATP), has at least one processor to configure the SP as a GUI for the OBU, and to enable WAVE authentication of the SP through a networked Road Side Unit. Preferably, the OBU opens, after a command from an ATP Client, a virtual connection for streaming data between the vehicle data bus and a remote server providing an automotive scan tool. Also preferably, the SP may use either cellular or IEEE 802.11 control signals to trialaterate its geographic position with greater accuracy than GPS, and to hand off the geo-position fixes to the OBU. Accumulated geo-location information may be reported to a remote server, providing a centralized geographic trend analysis of plural SPs operating with OBUs.
