A Solution Design for Solving Road Deadlock in Autonomous Driving

With the rapid development of automatic control technology, self-driving cars have demonstrated their superior performance, but self-driving vehicles are often caught in a deadlock state surrounded by other vehicles, and unable to move forward or backward, which not only greatly reduces driving efficiency, but also easily causes traffic congestion and result in safety issues. In this paper, we address the definition of the deadlock states and analyze the possible reasons during autonomous driving. Based on vehicle-to-vehicle communication, the deadlocked state can be detected. And then forming a multi-vehicle coordination group through a cooperative manoeuvring procedure to realize collaborative driving with surrounding vehicles, so the locked vehicles can get rid of the deadlock state, and the congestion can be avoided and the driving efficiency can be improved.
