<p>In automobile industry, ultra-compact mobility is proposed to streamline transportation. In recent years, ultra-compact mobility utilized for car sharing service in urban area and sightseeing spot. However, there is a possibility that ride comfort is exacerbated because ultra-compact mobility is simple equipment for miniaturization. To improve ride comfort against vertical vibration, we proposed an active seat suspension mounted on the seat section of the vehicle. The active seat suspension is possible to control vibration actively by means of using voice coil motor. On the contrary, the control considering velocity, acceleration and jerk of vertical vibration is required to make comfortable car for occupant. Therefore, it is necessary to grasp the thrust characteristics when the motor is greatly displaced. In addition, it is required to construct a control system that is robust against changes in the thrust constant due to displacement. Therefore, in this paper, the thrust characteristics of the voice coil motor which used in the active seat suspension will be clarified from the analysis. Moreover, we investigated control performance of voice coil motor based on simulation and experiment.</p>
