Abstract:
1. An electric suspension control apparatus disposed between a body and a wheel of a vehicle, and configured to adjust a thrust force of an electric actuator according to a thrust force instruction value output by a control unit, wherein at least one movement detection unit is connected to the control unit, the movement detection unit being configured to detect a movement state of the vehicle, wherein the control unit includes a required thrust force calculation unit configured to calculate a required thrust force value from a detection value detected by the movement detection unit, a frequency band determination unit configured to distribute the calculated value of the required thrust force calculation unit to a plurality of frequency bands, a limiter provided for each of the frequency bands to which the calculated value is distributed by the frequency band determination unit, and a thrust force instruction value calculation unit configured to generate the thrust force instruction value by combining an output value by the limiter for each frequency band, and wherein a limit value of the limiter is set in such a manner that the a value in a low frequency band as one of the frequency bands is smaller than a value in a high frequency band as another of the frequency bands.
