Abstract
Provided is an electromagnetic suspension apparatus capable of achieving both of vibration isolation performance and road holding performance. The electromagnetic suspension apparatus includes an electromagnetic actuator, an information acquisition unit that acquires information on a stroke speed of the electromagnetic actuator and a state quantity of the vehicle, a plurality of filters in which individual gain characteristics are respectively set, a filter setting unit that selectively sets a filter having a gain characteristic suitable for the state quantity of the vehicle from among the plurality of filters, a filter processing unit that performs a filtering process on a stroke speed signal using the filter set by the filter setting unit, and a drive control unit that controls driving of the electromagnetic actuator based on relationship information between the stroke speed after the filtering process and a damping force corresponding to the stroke speed.
