Saya Yamamoto･Ryu Atsuta (1FINITY Mobile Techno)

This study investigates a network bonding technique using multiple wireless interfaces to provide a stable communication environment for mobility systems. We measured wireless characteristics using a cellular measurement system based on smart devices and emulated the effectiveness of network bonding. We report the results of these evaluations.

Simulation-Based Evaluation of One-to-Many Remote Support for Automated Driving Services

Yanbin Wu･Toshihisa Sato･Naohisa Hashimoto (AIST)

In the implementation of Level 4 automated mobility services, operations in which a remote supervisor monitors multiple vehicles must achieve both safety and efficiency. This study developed a remote supervision simulator and conducted experimental evaluations of remote supervision tasks and operational simulations to examine how the number of monitored vehicles affects safety and efficiency, as well as the operational constraints of one-to-many supervision.

Effect of Steering Torque Feedback Timing on Driver Control in Teleoperation Driving

Ryotaro Hosoi･Keiji Jimi (Gunma University)･Toshiki Kanbayashi (SUBARU/Gunma University)･Ren Okuma･Hisato Fukuda (Gunma University)･Toshihiko Kozai･Tsutomu Iwase (Gunma University/SUBARU)

In teleoperated driving, steering resistance and reaction forces from the road surface are not transmitted to the driver, making stable steering difficult. In this study, we generate steering torque feedback using a non-linear tire model on a driving simulator. We evaluate its effectiveness for vehicle control assistance and report the results on how the presentation timing of steering torque feedback affects driver operations.

A Simulator Study on the Effects of Teleoperation Video Quality and Driving Support by White Line Enhancement

In teleoperation, the communication environment fluctuates significantly; however, stabilizing the connection can be expected by reducing video quality. Conversely, a decline in video quality degrades the perception of the surrounding environment, making stable maneuvering difficult. This study compares the effects of a low-resolution state with those of lane-marker enhancement, and reports the effects of lane-marker enhancement under low-resolution conditions on driving behavior.
