Autonomous vehicle positioning system for determining position of car for e.g. traffic management application, has host vehicle control unit for utilizing signal reception properties at reference points associated with broadcast messages

摘要

The system has a host vehicle control unit for identifying reference points along a road of travel, where each reference point identifies a position of a host vehicle (32) and signal reception property. The control unit selects a set of the reference points having identified positions and associated signal reception properties, utilizes the signal reception properties at reference points associated with received broadcast messages and determines position of a remote vehicle (30) as function of the signal reception property at each selected reference point. An independent claim is also included for a method for determining position of a remote vehicle relative to a mobile host vehicle based on safety alert messages broadcast from the remote vehicle related to event in a road of travel.
