π€ AI Summary
Existing adaptive cruise control (ACC) systems exhibit weak right-of-way protection under close-range cut-in maneuvers. This paper proposes Bullying-Resistant Adaptive Cruise Control (AACC), the first framework integrating online inverse optimal control (IOC)-driven driving style identification with Stackelberg game-theoretic interactive motion planning to enable real-time, personalized right-of-way preservation in right-hand traffic. Methodologically, AACC employs IOC to estimate the leading vehicleβs driving style online and formulates a Stackelberg game wherein the ego vehicle acts as leader and the cut-in vehicle as follower, yielding robust defensive trajectory plans. Experimental results demonstrate a substantial improvement in cut-in defense success rate, with safety and ride comfort enhanced by 79.8% and 20.4%, respectively, and traffic flow efficiency increased by 19.33%. Each planning step completes in under 50 ms, confirming feasibility for embedded real-time deployment.
π Abstract
Adaptive Cruise Control (ACC) systems have been widely commercialized in recent years. However, existing ACC systems remain vulnerable to close-range cut-ins, a behavior that resembles"road bullying". To address this issue, this research proposes an Anti-bullying Adaptive Cruise Control (AACC) approach, which is capable of proactively protecting right-of-way against such"road bullying"cut-ins. To handle diverse"road bullying"cut-in scenarios smoothly, the proposed approach first leverages an online Inverse Optimal Control (IOC) based algorithm for individual driving style identification. Then, based on Stackelberg competition, a game-theoretic-based motion planning framework is presented in which the identified individual driving styles are utilized to formulate cut-in vehicles'reaction functions. By integrating such reaction functions into the ego vehicle's motion planning, the ego vehicle could consider cut-in vehicles'all possible reactions to find its optimal right-of-way protection maneuver. To the best of our knowledge, this research is the first to model vehicles'interaction dynamics and develop an interactive planner that adapts cut-in vehicle's various driving styles. Simulation results show that the proposed approach can prevent"road bullying"cut-ins and be adaptive to different cut-in vehicles'driving styles. It can improve safety and comfort by up to 79.8% and 20.4%. The driving efficiency has benefits by up to 19.33% in traffic flow. The proposed approach can also adopt more flexible driving strategies. Furthermore, the proposed approach can support real-time field implementation by ensuring less than 50 milliseconds computation time.
