Researchers propose a neural network-based lane-change trajectory planner that uses dual-head architecture to balance safety guarantees with personalized driving preferences. The system adaptively switches between a baseline safe mode and a driver-specific comfort/efficiency mode based on contextual driving conditions, enabling autonomous vehicles to optimize maneuvers while maintaining feasibility across diverse scenarios.
Researchers propose a novel Vision-Language Navigation approach that grounds waypoints in executable trajectories rather than predicting isolated navigation points.

Researchers propose Sequential Navigation Guidance (SNG), a framework addressing a critical flaw in end-to-end autonomous driving systems that over-rely on local scene understanding while underutilizing global navigation information. The SNG framework combines navigation paths and turn-by-turn instructions with a new VQA dataset and efficient model to improve autonomous vehicle planning and navigation-following in complex scenarios.
Researchers introduced BEV-VLM, a new autonomous driving trajectory planning system that combines Vision-Language Models with Bird's-Eye View maps from camera and LiDAR data. The approach achieved 53.1% better planning accuracy and complete collision avoidance compared to vision-only methods on the nuScenes dataset.
Researchers introduce Max-V1, a novel vision-language model framework that treats autonomous driving as a language problem, predicting trajectories from camera input. The model achieved over 30% performance improvement on the nuScenes dataset and demonstrates strong cross-vehicle adaptability.
Researchers developed PC-Diffuser, a safety framework for autonomous vehicle trajectory planning that integrates certifiable safety measures directly into diffusion-based planning models. The system addresses safety failures in AI-driven autonomous vehicles by embedding barrier functions into the denoising process rather than applying safety fixes after planning.
