This paper discribes a investigation of the nonlinear filter which can change a high frequency gain and delaying phase independently. There have been a lot of the investigation of the driver-vehicle closed-loop system. But, even the optimal relationship between gain and phase are not yet found. For example, there is a proper value of the delaying phase in the vehicle dynamics. And when the delaying phase is too small, the driving easiness is reduced. However, generally in a linear system, a high frequency gain becomes larger as phase becomes smaller. It is impossible to define which is the main factor of driving difficulty, gain or phase. So, we tried to change a high frequency gain and delaying phase independently and experimented. Therefore, we applied the nonlinear filter to the driving simulator, and examined a change the subjectivity evaluation of the vehicle maneuverability and the experimental data.
