Abstract
A method includes: receiving, at a host vehicle, a plurality of messages transmitted using Vehicle-to-Vehicle (V2V) communications indicating a heading angle and a speed of a remote vehicle; 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; 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; and 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.
