In the previous paper, the authors proposed new characteristics of damping force of an ER damper that are expressed as a function of road profile and horizontal position of the damper on the road by piecewise linear form, and minimized the maximum acceleration of the sprung mass of a vehicle model with the ER damper. In this paper, we propose a method of multiobjective optimization that two objective functions, namely the maximum acceleration and maximum displacement of the mass of the vehicle model with the ER damper having a damping force revised for the high frequency vibration shown in the previous paper are minimized. As the result of the optimization, Pareto optimal solution is obtained using the ε-constant method, and the trade-off for the objective functions is analyzed. In addition, the optimum ER damper is compared with the optimum existing damper which the damping force is expressed as a function of piston speed of the damper.
