Abstract
This article describes the scope of vehicle dynamics control application on micro-scale electric vehicle for enhancing its active safety. The use of in-wheel-motor control in various control objectives as active safety devices are stated in the paper. In the first half of the paper, the control systems for enhancing vehicle dynamics are described. The active front steering by using steer-by-wire mechanism for improving vehicle handling and stability is mainly presented. The latter half of the paper presents the control system designed for driving assist system. The lane keeping control with torque distribution strategy is described. The theoretical controller design and experimental validation are shown in the paper

Summary
From the viewpoint of environmental concerns and energy conservation, advanced researches as well as development efforts in the field of low-emission vehicles have been extensively conducted. This paper mainly describes the scope of utilizing electric motor for controlling vehicle dynamics. Besides DYC system, as a part of the paper, the active front steering system utilizing electric motor is studied. The first half of the paper discusses about the steer-by-wire system which is equipped for the other micro electric vehicle “NOVEL-II”. It consists of two electric AC servo motors which are used for the control of front steering angle and steering reaction torque. The controller design and experimental validation are described In the latter half of the paper, a chassis control system which utilizes DYC as lane keeping assistance system for driver steering workload reduction. The functionality of lane keeping control with DYC are demonstrated and its effectiveness on lane keeping are verified
