Introduction
This study introduces a vision-language pipeline that detects risky driving behaviors and generates emotionally expressive responses to support driver awareness and comfort. Although vision-language models have advanced perception and reasoning in autonomous driving, existing systems rarely consider the emotional dimension or real-world user experience.
System Design
Keep Yelling Assistant (KYA) detects high-risk driving maneuvers in real time, such as sudden cut-ins, and produces emotional responses through a large language model tailored to driver preferences. The framework comprises two core modules:
- Vision module: Uses YOLOv8 variants to detect nearby vehicles and identify risky behaviors such as sudden cut-ins. Key driving metrics — relative distance, speed, and projected reach time — are extracted and normalized to produce a structured behavior log.
- Language module: Processes the behavior log with user-defined emotional tone settings (e.g., neutral, humorous, analytical) and generates verbal reactions using state-of-the-art LLMs including ChatGPT-4o, Claude 3, Gemini 2.5, and Copilot.
- All models received favorable ratings, although preferences varied across personas.
- The combination of YOLOv8s + ChatGPT-4o achieved the highest score: 4.29 / 5.00.
Evaluation
The system was evaluated using dashcam videos containing risky driving behaviors and a user study involving 108 participants. Participants selected preferred response styles, and the LLMs were evaluated based on emotional alignment.
Conclusion
By integrating real-world perception with emotionally adaptive dialogue, KYA introduces a new paradigm for emotionally intelligent in-vehicle artificial intelligence.
