ファジィ制御型可変特性操舵系による緊急回避シミュレーション

抄録

Steer by wire technology realizes a change of relationship between the steering wheel angle and the tyre steer angle in accordance with the running state of the vehicle or the environmental conditions during driving. In this research, a variable characteristics steering system (VCSS) using the steer by wire is proposed. Fuzzy control is used for the control of the VCSS. A computer simulation assuming an emergency avoidance situation is performed. According to comparing the vehicle with the VCSS to the normal vehicle, the relationship among driver's operation characteristics, vehicle motion, and each parameter of the VCSS is investigated. The possibility of improving emergency avoidance performance is found.
