Development of Driving Assist System Using Steer-by-Wire System

-Fundamental Consideration on Steering Burden on Driver due to Steering Amount and Reaction Torque-

Abstract

Currently, the elderly people have shown a strong desire to purchase ultra-compact mobility vehicle for one or two people, but since the body of the ultra-compact mobility vehicle is small, there is no enough space to install a system that supports steering operations such as power steering. Our research group is equipped with a steer-by-wire system, which is a small steering system, and is studying steering support for drivers. However, since the steering reaction torque that the driver feels appropriate is different for each person, the fundamental consideration of the burden evaluation for the steering reaction torque was conducted in this study.
