在使用自适应巡航控制和车道保持辅助系统的2级自动驾驶过程中，我们分析了39名测试对象的驾驶行为，同时在仪表板上安装的HUD上显示系统安全级别和驾驶员的驾驶准备水平。在驾驶模拟器调查中，基于驾驶员的注视动作和制动/油门踏板操作行为，对这种驾驶行为进行了分类。作为实验结果之一，当系统安全水平和驾驶准备水平同时呈现给驾驶员时，与不向驾驶员呈现信息的情况相比，用于风险规避的驾驶行为得到改善。当向驾驶员提供这两条信息时，驾驶员能够理解环境的任务要求，并表现出适当的驾驶行为，以保持驾驶员和自动驾驶系统的总体驾驶性能高于任务要求。
During automated driving categorized to the level 2 using Adaptive Cruise Control and Lane Keeping Assistance Systems, we analyzed the driving behaviors of 39 test subjects when presenting the system safety level and driving preparation level of drivers on HUD fixed on instrument panel. This driving behavior was classified, based on the gaze action and brake/gas pedal operation behavior of drivers, in a driving simulator investigation. As one of the experimental results, when system safety level and driving preparation level were presented to drivers simultaneously, the driving behaviors for risk avoidance was improved compared with a condition when the information was not presented to drivers. When presented with these two pieces of information, the driver was able to understand the task demands from the environment and showed appropriate driving behavior to keep the total driving performance of driver and automated driving system higher than the task demands.
