摘要：

为了提高驾驶员、车辆组成的人-车闭环系统的综合性能,提出一种变传动比反馈方法.根据车速与转向盘转角设计了模糊控制的变传动比策略,仿真表明该策略产生的传动比变化平滑,能改善驾驶员疲劳指标.将该策略与横摆角速度反馈结合,形成基于模糊控制的变传动比反馈方法.采用该方法在车辆模拟器上进行2种车速下的双移线试验和蛇形试验.结果表明：该方法与横摆角速度反馈或定传动比控制相比更加有效,转向盘的转角变化范围最小,降低了驾驶员疲劳程度,同时保证了车辆操纵的稳定性,使得人-车综合性能指标得到了明显改善.
Abstract:

A changeable steering ratio feedback method was described to improve the comprehensive performance of human-vehicle closed-loop system formed by driver and vehicle.  A fuzzy control strategy of changeable steering ratio was designed according to vehicle speed and steering angle. Simulation showed that the change of steering ratio calculated by this strategy was smooth, and the driver tiredness indicator was improved. This strategy was combined with the yaw rate feedback to form a changeable steering ratio feedback method based on fuzzy control. This method was applied to vehicle simulator to perform double shift line experiment and serpentine experiment under two vehicle speeds. The results show that this method is more feasible than the yaw rate feedback and the constant steering ratio control, the range of steering angle change is the minimum, the drivers tired level is reduced and the vehicle handling stability is maintained at the same time, and the human-vehicle comprehensive performance indicator is optimized significantly．
