"The best feeling for steering", one goal of an automotive engineer, is concerned with how much information between a vehicle and road is provided. In this paper, we regard the road information as a frequency band of a tire-steering wheel transmission characteristics, and propose the method to supply the road information to driver by using the systematic control design with "generalized plant" and "H-infinity control". In addition, we prove its effectiveness by an experiment, and the Electric Power Steering (EPS) system is suitable to supply the road information because it has more freedom for designing steering characteristics.
