Abstract
Provided is an electric suspension device including an electromagnetic actuator that is provided between a body and wheel of a vehicle and generates a load for damping vibration of the body. It includes: a camera that detects preview image information of a road surface in front of the vehicle; a 3D gyro sensor that detects a sprung speed of the vehicle; a target load computation unit that computes a target load based on the preview image information and the sprung speed; and a load control unit that controls the load of the actuator by using the computed target load. When a detection result based on the preview image information indicates that the front road surface is even but a detection result based on the sprung speed indicates that the front road surface is uneven, the target load computation unit computes the target load based on the sprung speed.
