The various kinds of the electric personal mobility, which is one or two-seater, are being developed all over the world. These mobilities are applied into the substantiative experiment held in the several cities in order to investigate the effectiveness and popularity. The main specification of the personal mobility is the small footprint to reduce the parking space and alleviate traffic jam. However, the small footprint causes the deterioration of the posture stabilization. The authors are developing the personal mobility, which has a lean actuator to tilt the upper body for keeping the posture stabilization not only during turning motion but also on the uneven road surface. In this paper, the motion model considering yaw motion around roll axis is derived. In addition, the posture control method based on the motion model is proposed to realize the desired roll angle, which ensures the required range of the zero moment point. The effectiveness of the proposed approach is verified by the experiments using a prototype.
