理想VLM/VLA盲区减速差异

Core Insights - The article discusses the differences between VLM (Visual Language Model) and VLA (Visual Language Action) in the context of autonomous driving, particularly focusing on scenarios like blind spot deceleration [1][2]. Group 1: VLM and VLA Differences - VLM operates by perceiving scenarios such as uncontrolled intersections and outputs a deceleration request to the E2E (End-to-End) model, which then reduces speed to 8-12 km/h, creating a sense of disconnection in the response [2]. - VLA, on the other hand, utilizes a self-developed base model to understand the scene directly, allowing for a more nuanced approach to blind spot deceleration, resulting in a smoother and more contextually appropriate response based on various road conditions [2]. Group 2: Action Mechanism - The action generated by VLA is described as a more native deceleration action rather than a dual-system command, indicating a more integrated approach to scene understanding and response [3]. - There are concerns raised in the comments regarding VLM's reliability as an external module, questioning its ability to accurately interpret 3D space and the stability of its triggering mechanisms [3].
