摘　　要：以宝马轿车上选装的主动转向系统为例,详细介绍了该系统的组成、双行星齿轮机构的结构及工作模式,以及该系统可变传动比、稳定车辆等功能的实现原理和系统安全性设计。指出通过与其他动力学控制系统一起实现底盘一体化集成控制将是主动转向技术未来的发展方向。As an example, the structure and working modes of active front steering （AFS） system and its double planetary gear mechanism of a BMW car are presented. The implementation of variable gear ratio and vehicle stability control as well as system safety design are discussed in detail. It is pointed out that using the system, together with other dynamics control systems to realize integrated chassis control is the development trend of AFS technology in the future.

关 键 词：主动转向 可变转向传动比 稳定性控制
