Generative and Agentic AI for Connected and Autonomous Systems

Research question

What can multimodal and language models understand about a driving scene, and how can their outputs support useful interaction? Collaborative research develops driving-scene benchmarks, instruction-based interfaces over established driving functions, and scene-grounded dialogue. Complementary studies investigate scenario generation, traffic simulation, and selective reasoning, each with its own evaluation task.

Methods & contributions

  1. Making model capabilities testable

    NuPlanQA provides multi-view driving-scene question answering and evaluates perception and spatial reasoning. PDB-Eval tests descriptions and explanations of personalized behavior. Concept-bottleneck control studies explanations through human-understandable concepts.

  2. Connecting instructions to existing driving functions

    LaMPilot studies language-model programs over established driving functions. LLM4AD contributes a collaborative review, benchmark, and vehicle-platform experiments that examine language models in autonomous-driving applications.

  3. Scene-grounded dialogue with driver confirmation

    SC-ADAS combines scene interpretation, multi-turn dialogue, and structured function calling. Driver-confirmed requests are converted to ADAS commands; evaluation examines interaction behavior and the latency and context costs of cloud-based generative models.

  4. Generating scenarios and simulating traffic

    SIMSplat studies language-aligned driving-scenario generation with 4D Gaussian splatting, while NIVA studies learned closed-loop multi-agent traffic simulation.

  5. Selecting when reasoning runs

    Tonic meta-control maintains a persistent vigilance state to decide when costly reasoning modules run, evaluated with a synthetic testbench and highway driving simulation.

  6. Related agentic and language-system applications

    Coauthored studies explore agentic trip planning and input-ambiguity detection in language models.
