Masaki Kuge･Hailong Liu (Nara Institute of Science and Technology)･Toshihiro Hiraoka (JARI)･Takahiro Wada (Nara Institute of Science and Technology)

Level 3 automated driving vehicles may exhibit irregular and unstable vehicle behavior when requesting the driver to take control, increasing the risk of other vehicles being involved in traffic accidents. This study aims to verify the effectiveness of accident prevention through information cues to other vehicles during the request to intervene via eHMIs.

Relationship between Kansei Evaluation and Sound Quality Characteristics of Operating Sound of Haptic Switch

Hajime Yasuda･Tomotaka Igarashi (Nissan Motor)･Akinari Hirao (Shibaura Institute of Technology)

Many kinds of switches are used inside the cabin. Recently, the switches without stroke tend to be used by technology advances and styling demands. In this study, the evaluation structure of operation sound and the sound quality characteristics were analyzed for haptic switch that are the new type of push switches operating by finger.

Verification of Operability and Strength of Variable Steering Wheel throught Analysis

Dongmin Kim･Hyeonmuk Kim (KOMOS)

The purpose of this study is to verify through analysis the operational performance of the variable steering wheel, which is being developed to improve driver convenience as autonomous vehicle driving technology develops. For future autonomous driving levels 3 and above, entertainment inside the vehicle is becoming more important. Accordingly, securing driver's seat and interior space is becoming essential and important, and the need to hide the steering wheel as a technical solution is being highlighted. We are currently developing a folding/unfolding steering wheel, and NVH, strength, fatigue durability, etc. are verified and analyzed through analysis of problems that arise when the steering wheel is folded/unfolded.
