This paper describes an investigation on the nonlinear filter that can realize its gain and phase independently. In the driver-vehicle closed loop system， it is reported that there is an optimal value in vehicle phase delay. Therefore excessively large or small delay deteriorates vehicle maneuverability. However， there is a strict relationship between the gain and phase delay in linear system. It is difficult to evaluate the gain and phase delay of vehicle response independently. In this investigation， we tried to design a non-linear filter that can set the relationships between the gain and phase delay arbitrarily. We investigate effect of the gain and phase delay corresponding to the steering angle input on the ease of driving by using driving simulator，and evaluate the control performance on the lane change task. We verified the ease of driving by reducing a phase delay and decreasing a high frequency gain.
