  In this paper, we investigate the decision making of autonomous vehicles in
an unsignalized intersection in presence of malicious vehicles, which are
vehicles that do not respect the law by not using the proper rules of the right
of way. Each vehicle computes its control input as a Nash equilibrium of a game
determined by the priority order based on its own belief: each of non-malicious
vehicle bases its order on the law, while a malicious one considers itself as
having priority. To illustrate our method, we provide numerical simulations,
with different scenarios given by different cases of malicious vehicles.
