Abstract:
1. An autonomous vehicle positioning system of a mobile host vehicle identifying malicious communication activity broadcast by a remote vehicle involved in an accident, the system comprising: a host vehicle communication unit communicating with the remote vehicle for receiving safety alert broadcast messages from the remote vehicle, the safety alert broadcast messages including notification of the remote vehicle's involvement in the accident; a host vehicle control unit identifying reference points along the road of travel, each reference point identifying a position of the host vehicle and a signal reception property when the host vehicle receives the safety alert broadcast message from the remote vehicle involved in the accident; and wherein the host vehicle control unit selects a set of the reference points having identified positions and associated signal reception properties, wherein the host vehicle control unit utilizes the signal reception properties at each reference point associated with the received safety alert broadcast message, wherein the host vehicle control unit determines a position of the remote vehicle as a function of the signal reception properties at each selected reference point in the set, wherein each reference point identifies a position of the host vehicle and associated signal reception properties when the host vehicle receives the safety alert broadcast message, wherein the host vehicle control unit determines whether the remote vehicle involved in the accident broadcasting the safety alert message is either mobile or not in a vicinity of the accident based on the associated signal reception properties at each reference point, and wherein the host vehicle control unit determines misbehavior by the remote vehicle involved in the accident if the determination is made that the remote vehicle is either mobile or not in a vicinity of the accident.
