车企的辅助驾驶体系正加速转向AI。一个鲜明的表征是，头部新势力的车端辅助驾驶模型参数，已接 近许多AI大模型的参数量级。 36氪汽车了解到，小鹏汽车即将部署在车端的大模型，其参数量至少是70亿；另一家头部新势力理想汽 车，待明年它自研的辅助驾驶芯片上车后，其车端大模型参数也将来到70亿级。 这样的参数量已接近AI大模型的普遍参数量级。 小鹏、理想的AI布局 小鹏的车端大模型，是由内部正在开发的云端大模型——"小鹏世界基座大模型"蒸馏而来。之所以如 此，主要是为了应对车载辅助驾驶芯片算力、存储、内存带宽不足，从而无法直接在车端部署大模型的 问题。 2024年下半年，小鹏汽车开始向云端大模型迈进。目前，小鹏正在研发一个720亿参数打底的超大规模 自动驾驶大模型，即 "小鹏世界基座模型"，将在下个月的AI科技日上发布。 小鹏在今年4月的AI技术分享会上介绍，这个云端大模型，以LLM为骨干网络，使用海量多模态驾驶数 据训练，具备视觉理解、链式推理和动作生成能力。小鹏在云端完成对这一模型的训练后，会"取其精 华"，将蒸馏出的小模型部署到车端。 这种方法，参考的是DeepSeek已经使用过的知识蒸馏路线，其本质上是模型的 ...
