Autonomous Cooperative Driving Protocol Based on the Security Status of IVN

Autonomous cooperative driving determines the optimal operating conditions and route based on information acquired by the own vehicle and information provided by surrounding vehicles. The cooperative driving environment is an environment with a high probability of accidents such as lane change, overtaking, avoidance, cutting in, intersection, and merging. In addition, the reliability and integrity of the data transmitted by the other vehicle in the cooperative driving must be ensured. This paper proposes a method to proceed/abandon/ignore/warning of autonomous cooperative driving based on exchanging information on security status of In-Vehicle Network (IVN) and safety status through vehicle communication for successful cooperative driving of autonomous vehicles.
