Autonomous high-density platooning imposes one of the most demanding requirements to Ultra-Reliable Low-Latency Communications (URLLC) for today's Vehicle-to-Vehicle (V2V) networks. Cooperative Adaptive Cruise Control (CACC) systems developed in recent years require resilient communication to prevent collisions among vehicles of the platoon and to prevent distance error amplification along the platoon. On the other hand, modern CACC algorithms need to handle sudden network outages, which are rare but inevitable in wireless communication.
In this research, both the challenges of the communication system and the control system are addressed. Firstly, a characterization and requirement definition of the state-of-the-art communication technology such as Dedicated Short-Range Communications (DSRC) and the Device-to-Device (D2D) mode of 5th Generation (5G) / 5G Advanced cellular networks is modeled analytically. Secondly, this information is used to define reliability requirements of safe high-density platooning systems and to work towards safety bounds of state of the art CACC systems and enhanced collision-free CACC algorithms.
