<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic suspension system with high practical utility. <P>SOLUTION: An actuator is structured so as to be connected with either one of a sprung portion and an unsprung portion through a supporting spring. When a deformation amount x<SB>4</SB>of the supporting spring is more than a set point (S4), for example, such a control (S15 to S16) as to generate an actuator force corresponding to a motor rotational angular speedωis executed, for example, so that the actuator force entirely may become a resistance force against a relative operation between a sprung portion unit and an unsprung portion unit in place of standard control (S9 to S12) for generating an actuator force of a magnitude in accordance with a predetermined control rule. Hence, for example, when wheels run over protrusion portions or recess portions, an approach/separation operation between the sprung portion and the unsprung portion can be prevented from stopping, or even if an approach/separation operation is stopped, an impact generated upon the stopping can be effectively relieved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
