Collaborative driving, enabled by the integration of communication among automated vehicle systems, holds great potential to enhance transportation safety and efficiency. One prominent application in this area is Cooperative Adaptive Cruise Control (CACC), particularly in vehicle platooning, which has garnered significant research attention. However, communication disruptions—caused by issues such as signal obstruction, weak transmission, or equipment malfunctions—can compromise the stability of vehicle strings and increase the risk of collisions. To address this challenge, this study introduces a fallback mechanism for the CACC system. Specifically, when communication failures occur, the system transitions to the ACC2 mode, leveraging onboard sensors to maintain operations. The effectiveness of this approach in preserving string stability is demonstrated through a series of comparative analyses and numerical simulations.
