自動運転における監視制御および異常時対応に関するドライビングシミュレータ実験

抄録

In SAE J3016 autonomous level 3 (conditional driving automation), the driver must monitor the system, and in case of a system error, the transition to manual driving must be performed. However, it is unknown for general drivers whether it is possible to drive properly under such circumstances. In this study, we conduct a driving simulator experiment to observe the behavior of the driver when the transition to manual. In the experiment, we simulate a situation where the system error occurres in the autonomous vehicle for some reasons and the authority of driving have to be transferred to the driver. The system error occurs when the autonomous vehicle running on a curved road of highway at 100 km/h. Then, if the driver does not operate, the car collides with the preceding vehicle or the curb road. From the experiment data, we analyze the characteristics of the transition to manual due to the system error, and propose the cause of the problem.
