1. A method comprising:

  • receiving, at a host vehicle, a plurality of messages transmitted using Vehicle-to-Vehicle (V2V), wherein the plurality of messages are Basic Safety Messages (BSM) with a part for core safety data and a part for optional safety data;

    determining a heading angle and a speed of a remote vehicle according to the plurality of messages received using V2V communications;

    calculating an expected change in frequency of the plurality of messages received at the host vehicle based on the heading angle and the speed of the remote vehicle determined according to plurality of messages received using V2V communications;

    measuring an actual change in frequency of the plurality of messages received at the host vehicle due to the Doppler effect;

    comparing the expected change in frequency to the actual change in frequency;

    determining that the plurality of messages were not transmitted from the remote vehicle when a difference between the expected change in frequency and the actual change in frequency exceeds a predefined frequency change threshold; and

    performing automatic control of the host vehicle according to received V2V messages excluding the plurality of messages in response to determining that the plurality of messages were not transmitted from the remote vehicle.
