Summary: | When multiple agents share space, interactions can lead to deadlocks, where
no agent can advance towards its goal. This paper addresses this challenge with
a deadlock recovery strategy. In particular, the proposed algorithm integrates
hybrid-A$^\star$, STL, and MPPI frameworks. Specifically, hybrid-A$^\star$
generates a reference path, STL defines a goal (deadlock avoidance) and
associated constraints (w.r.t. traffic rules), and MPPI refines the path and
speed accordingly. This STL-MPPI framework ensures system compliance to
specifications and dynamics while ensuring the safety of the resulting
maneuvers, indicating a strong potential for application to complex traffic
scenarios (and rules) in practice. Validation studies are conducted in
simulations and on scaled cars, respectively, to demonstrate the effectiveness
of the proposed algorithm. |
