複数のHMIを搭載したインピーダンス制御を用いた操舵支援システムの受容性評価

抄録

In this research, we aim to evaluate the acceptability of the steering intervention support system introducing the impedance control of the steering torque command equipped with multiple HMIs such as HUD and sound effects.

Using the damping ratio as an evaluation index, we examine the change of the damping ratio that compatible with acceptability and safety by changing the use situation of HMI. Experimental results of subjective and objective evaluation showed that the system acceptability of the driver improved by introducing the sound effect 1 second before, and it was confirmed that the steering safety improves in the low damping ratio range.
