Injecting Hallucinations in Autonomous Vehicles: A Component-Agnostic Safety Evaluation Framework

Nascimento, A.; Shimanuki, G.; Vismari, L.; Camargo Jr., J.; Almeida Jr., J.; Cugnasca, P.; Queiroz, A.; Bailenson, J.

arXiv. 2025. Under Review

We introduce a new safety framework that finds critical autonomous vehicle weaknesses by making the system 'hallucinate' fake sensor data.

Analysis of the Influence of the Safety Zone on the Effectiveness of the Lateral Control Algorithm for Lane Change in Autonomous Vehicles

Shimanuki, G.

30th University of São Paulo's International Symposium of Undergraduate Research. 2022.

This study uses an AV simulator (OpenDS) to analyze how adding a virtual 'Safety Zone' to a control algorithm improves vehicle safety during lane conversions.

Analysis of the Influence of the Safety Zone on the Effectiveness of the Lane Crossing Control Algorithm for Autonomous Vehicles

Shimanuki, G.

29th University of São Paulo's International Symposium of Undergraduate Research. 2021.

This simulation study analyzes two 'Safety Zone' strategies, showing that applying the virtual safety buffer to all vehicles (not just the AV) is more effective for safe lane crossing.
