A Multi-Vehicle Longitudinal Trajectory Collision Avoidance Strategy Using AEBS With Vehicle-Infrastructure Communication

Shortening inter-vehicle distance can increase traffic throughput on roads for increasing volume of vehicles. In the process, accidents occur more frequently, especially multi-car accidents. Furthermore, it is difficult drivers to drive safely under such complex driving conditions. This article investigates multi-vehicle longitudinal collision avoidance issue conditions based Advanced Emergency Braking System (AEBS). AEBS used avoid collisions or mitigate impact during critical situations by applying brake automatically. Hierarchical controller proposed guarantee safety multi-cars using Vehicle-to-Infrastructure (V2I) communication capability in addition radar vehicle control. High-level designed ensure and optimize total energy calculating target braking force. Vehicle network get key vehicle-road interaction data constrained hybrid genetic algorithm (CHGA) adopted decouple interactive system,which obtain maximum ground friction through data, provide predictive parameters controller. Lower level non-singular Fractional Terminal Sliding Mode(NFTSM) Controller built achieve control goals high-level Simulations are carried out typical Results verify that system this risk compared without system.
