摘要

For human-driven as well as autonomous vehicles, one of the key requirements is continuous awareness of the surroundings to detect any potential threats (vehicles, pedestrians, wild-life etc.). This requires continuous cooperation between the vehicles by efficiently sharing safety information in a timely manner. However, this is a multi-dimensional and challenging problem due to the complex nature of the vehicular environment. To solve this problem, this paper proposes an elegant solution to efficiently share the safety information among vehicles by using only Basic Safety Messages (BSM), which are part of the existing V2V standards. Through this research, the vehicles are able to quickly and preemptively identify potential threats, not only in their close proximity, but also those which are further along the roadway by intelligently exchanging safety information between neighboring vehicles. Additionally, for the first time, the proposed architecture presents a practical approach of incorporating the onboard sensor data with the V2V communications. This leads to vehicles having improved visibility and situational awareness further outside of their one-hop coverage. Simulation results show that improved visibility of vehicles up to 2.6 km can be achieved while placing minimum overhead and complexity on the network.
