An event-triggered real-time motion planning strategy for autonomous vehicles

Abstract: Motion planning is an essential part of autonomous vehicles. The planning process should respond to environmental changes in real time to ensure safety. This paper proposes an event-triggered real-time motion planning strategy to achieve a more real-time planning effect and a scenario-based planning process. The path planning process is discretized into several parts and integrated into the behavioral planning process. A hierarchical finite state machine (HFSM) based integrated motion planning process is propo… Show more

“…Rule-based path planning strategies are widely used in autonomous driving systems [4] and the planning results are strictly constrained by the planning process, i.e., if the inputs are unchanged, the output path remains unchanged [5,6]. The driving path can be obtained using the curve-fitting-based planning strategies through fitting functions.…”

“…This work aims to provide a flexible, accurate, and efficient path planning strategy for autonomous vehicles traveling on half-structured roads: (1) bringing higher efficiency compared to traditional sampling strategies, especially in vast areas [4]; (2) bringing more flexibility compared to state machine-based planning strategies and avoiding unintended hazards due to fault transmission [15]; and (3) bringing a higher degree of interpretability compared to numerical optimization strategies [16], where the output paths are filtered from within the path candidates.…”
