A Study on the Driver’s Response Performance according to Modality of Planned TOR in Automated Driving

This work represents the heuristic experiments and the results of transition performance from automated driving to manual in terms of the modality channel usage for take-over request (TOR). The heuristic experiments are designed with the dependent measurements and the independent conditions. Statistical analysis is performed to obtain claims about the modality channel of TOR.

I. Introduction

The driver’s role in the automatic driving system depends on the automatic driving phase. In Society of Automotive Engineering (SAE) J3016, the level of automated driving has been changed from manual driving (level 0) to total driving automation (level 5). The driver’s role is highlighted from level 0 to level 3, and above level 4, the driver’s involvement is removed [1] . Therefore, level 3 is conditional automation and the route to the destination consists of stages where the driver operates manually and stages where the automatic driving system (ADS) automatically operates.
