本文提出了一种方向盘反转率指标，旨在评估次要任务（例如与车载信息系统交互）对车辆横向控制性能的影响。该指标与许多其他常见的方向盘指标在视觉和认知次要任务负载的敏感性方面进行了比较。结果表明，所提出的反转率度量以及现有的转向熵度量在整个实验条件下是最敏感的。系统地研究了该指标的不同参数设置，并推荐了捕捉视觉和认知次要任务负荷影响的合适值。有关封面摘要，请参阅 ITRD E134653。
This paper presents a steering wheel reversal rate metric intended for assessment of the effects of secondary tasks, such as interacting with in-vehicle information systems, on vehicle lateral control performance. The metric was compared to a number of other common steering wheel metrics with respect to the sensitivity to visual and cognitive secondary task load. It was shown that the proposed reversal rate metric, together with the existing steering entropy metric, was the most sensitive across experimental conditions. Different parameter settings for the metric were systematically investigated and suitable values for capturing the effects of visual and cognitive secondary task load recommended.
