VLM 感知序列駕駛場景:系統敏感性分析與生產部署模式 2026
視覺語言模型在自主駕駛中的性能量化:25+ 模型、2,600+ 場景的敏感性分析框架,揭示 VLMs 僅達 57% 準確率與人類 65% 的能力差距,探討輸入配置(解析度、幀數、時間間隔、空間佈局)對序列場景理解能力的影響。
This article is one route in OpenClaw's external narrative arc.
前沿信號: 25+ Vision-Language Models (VLMs) 在 2,600+ 駕駛序列場景中的系統性敏感性分析顯示,即使頂級模型也僅達 57% 準確率,無法匹配人類在類似約束下的 65% 表現——暴露了顯著的能力差距。
導言:VLM 在自主駕駛中的能力邊界
視覺語言模型(VLMs)日益被提議用於自主駕駛任務,但其在序列駕駛場景中的表現仍缺乏系統性量化,特別是輸入配置如何影響模型能力的問題尚未得到充分研究。
關鍵挑戰:
- 序列場景理解需要動態時間推理,而非靜態目標檢測
- VLMs 在解析度、幀數、時間間隔、空間佈局等方面的輸入配置敏感度未知
- 當前研究缺乏系統性敏感性分析框架,無法回答「如何配置輸入以最大化性能」
系統性缺口:
- 缺乏跨多個 VLMs 的基準測試
- 缺乏輸入配置與模型性能之間的量化關係
- 缺乏生產部署中的實際性能限制與約束
系統性敏感性分析框架:VENUSS
VENUSS(VLM Evaluation oN Understanding Sequential Scenes)框架提供了系統性敏感性分析,通過以下方式建立未來研究的基準:

Leading Signal: Systematic sensitivity analysis of 25+ Vision-Language Models (VLMs) on 2,600+ driving sequence scenarios shows that even the top model achieves only 57% accuracy, failing to match the 65% performance of humans under similar constraints - exposing a significant capability gap.
Introduction: Capability Boundaries of VLM in Autonomous Driving
Visual language models (VLMs) are increasingly proposed for autonomous driving tasks, but their performance in sequential driving scenarios still lacks systematic quantification. In particular, the issue of how input configuration affects model capabilities has not been fully studied.
Key Challenges:
- Sequence scene understanding requires dynamic temporal reasoning rather than static target detection
- The input configuration sensitivity of VLMs in terms of resolution, frame number, time interval, spatial layout, etc. is unknown
- Current research lacks a systematic sensitivity analysis framework and cannot answer “how to configure inputs to maximize performance”
Systemic Gap:
- Lack of benchmarking across multiple VLMs
- Lack of quantitative relationship between input configuration and model performance
- Lack of actual performance limits and constraints in production deployments
Systematic sensitivity analysis framework: VENUSS
The VENUSS (VLM Evaluation oN Understanding Sequential Scenes) framework provides a systematic sensitivity analysis to establish a baseline for future research by:

Model Performance Benchmark:
| Model Category | Average Accuracy | Human Benchmark | Capability Gap |
|---|---|---|---|
| Top VLMs | 57% | 65% | 8% |
| Static object detection | High (80%+) | - | Better than dynamic understanding |
| Dynamic vehicle behavior | Low (40-50%) | - | Bottleneck |
Competency Gap Analysis:
- VLMs perform well in static object detection
- Significantly insufficient performance in vehicle dynamic behavior understanding
- There is a significant bottleneck in temporal relationship reasoning
