生態学的マルチモーダルインタフェースを用いた車両状態提示がステアバイワイヤ車両の運転行動に与える影響

抄録

The present paper reconsiders the active four-wheel steering controller and the steering reactive torque presentation method, which were proposed in the previous studies, from the viewpoint of an ecological interface design. It shows that drivers can intuitively understand how the control law works and the haptic interface enables drivers to perceive the vehicle state. Moreover, an ecological multimodal interface, which presents visual information about longitudinal and lateral accelerations based on the concept of friction circle in addition to the haptic information, is proposed to inform the road surface condition and the working state of the vehicle control system intuitively and comprehensibly. Driving simulator experiments verify the effectiveness of the proposed multimodal interface.
