Integrated Simulator for Evaluating Cooperative Eco-driving System

초록

In recent years, connected and automated vehicles (CAVs) have attracted considerable attention because they can improve driver convenience and safety using vehicle to everything (V2X) communication. CAV system must satisfy safety and performance requirements, and they are required to go through rigorous evaluation processes. In this study, we design an integrated simulator to evaluate a CAV system, cooperative eco-driving system, which models vehicular ad hoc network (VANET) topology, driver models, vehicle models, and vehicle control algorithms. This is done by integrating three simulators: network simulator, traffic simulator, and driving simulator. Cooperative eco-driving system requires precise and accurate map data including real-time traffic conditions and surrounding environmental information. Therefore, we construct a local map system based on V2X communication to provide a host vehicle (HV) with surrounding traffic and environment information. A local map system generates a local map by utilizing surrounding traffic information of HV acquired from each simulator and shares it with the simulators.
