Abstract
In general, several kinds of curve information are needed in the feedforward control of the tilting train. However it is preferable to simplify the control system. This paper deals with the possibility of optimal preview control for tilting vehicle to make simpler the control system of car body tilting. The control system uses only start and end points of transition curve as necessary information. Here it is assumed that the car body roll velocity is constant. As a result, it is shown that the proposed optimal preview control system can reduce the lateral acceleration on transition curve and variation of car body roll vibration than the natural tilting system.
