Abstract
An electrically powered suspension system includes: an electromagnetic actuator provided between a vehicle body and a wheel of a vehicle and configured to generate a damping force for damping vibration of the vehicle body; a wheel speed sensor that detects a wheel speed of the wheel; a wheel speed variation amount calculation part that calculates a wheel speed variation amount on the basis of wheel speed detection values detected by the wheel speed sensor; a 3D gyro sensor that detects sprung state amounts including a sprung pitching action of the vehicle; and a wheel speed variation amount correction part that estimates a variation component in the wheel speed variation amount on the basis of a sprung pitch amount and corrects the wheel speed variation amount so as to reduce the estimated variation component.
