Parameter Setting and Driver Acceptability Evaluation of Steering Assistance System Using Impedance Control by Damping Ratio

摘要

In this paper, we introduce an adaptation to steering assistance systems for providing impedance control. We also suggest using the damping ratio as a design guideline for the parameters of the impedance control. In our research, experiments were conducted with experimental participants using a driving simulator implementing the suggested steering assistance system. As a result of both subjective and objective evaluations, it was found that the suggested steering assistance system is better accepted by drivers than the conventional system. Moreover, the use of the damping ratio as an evaluation index facilitates the design of the impedance parameters. These results indicate the effectiveness of our suggested system.
