Safe Optimal Interactions Between Automated and Human-Driven Vehicles in Mixed Traffic with Event-triggered Control Barrier Functions
Anni Li, Christos G. Cassandras, Wei Xiao
This paper studies safe driving interactions between Human-Driven Vehicles (HDVs) and Connected and Automated Vehicles (CAVs) in mixed traffic where the dynamics and control polici…
Trust-Aware Resilient Control and Coordination of Connected and Automated Vehicles
H M Sabbir Ahmad, Ehsan Sabouni, Wei Xiao +2
We address the security of a network of Connected and Automated Vehicles (CAVs) cooperating to navigate through a conflict area. Adversarial attacks such as Sybil attacks can cause…
Optimal Control of Connected Automated Vehicles with Event-Triggered Control Barrier Functions: a Test Bed for Safe Optimal Merging
Ehsan Sabouni, H. M. Sabbir Ahmad, Wei Xiao +2
We address the problem of controlling Connected and Automated Vehicles (CAVs) in conflict areas of a traffic network subject to hard safety constraints. It has been shown that such…
SafeDiffuser: Safe Planning with Diffusion Probabilistic Models
Wei Xiao, Tsun-Hsuan Wang, Chuang Gan +1
Diffusion model-based approaches have shown promise in data-driven planning, but there are no safety guarantees, thus making it hard to be applied for safety-critical applications.…
Learning Robust and Correct Controllers from Signal Temporal Logic Specifications Using BarrierNet
Wenliang Liu, Wei Xiao, Calin Belta
In this paper, we consider the problem of learning a neural network controller for a system required to satisfy a Signal Temporal Logic (STL) specification. We exploit STL quantita…
Learning Stability Attention in Vision-based End-to-end Driving Policies
Tsun-Hsuan Wang, Wei Xiao, Makram Chahine +3
Modern end-to-end learning systems can learn to explicitly infer control from perception. However, it is difficult to guarantee stability and robustness for these systems since the…
Auxiliary-Variable Adaptive Control Barrier Functions for Safety Critical Systems
Shuo Liu, Wei Xiao, Calin A. Belta
This paper studies safety guarantees for systems with time-varying control bounds. It has been shown that optimizing quadratic costs subject to state and control constraints can be…
Learning Feasibility Constraints for Control Barrier Functions
Wei Xiao, Christos G. Cassandras, Calin A. Belta
It has been shown that optimizing quadratic costs while stabilizing affine control systems to desired (sets of) states subject to state and control constraints can be reduced to a…
Learned Risk Metric Maps for Kinodynamic Systems
Ross Allen, Wei Xiao, Daniela Rus
We present Learned Risk Metric Maps (LRMM) for real-time estimation of coherent risk metrics of high dimensional dynamical systems operating in unstructured, partially observed env…
