自動車用可変特性操舵系における微分制御の効果とファジィ推論によるパラメータ決定手法

抄録

A steer-by-wire technology creates new automobile steering control that was impossible in past days. Since this technology can vary the characteristics of the steering system, the characteristics adapted to drivers and running conditions can be made. In this study, we conduct a simulation of the variable characteristics steering system in an emergency lane change to avoid an obstacle on a road. We use PID control for the variable characteristics steering system, and the values of the proportional gain and the differential gain are determined moment by moment by fuzzy control. The usefulness of the variable characeristics steering system with fuzzy gain-switching is clarified.
