Abstract: Provided is an electric suspension device including an electromagnetic actuator that is provided between a body and wheel of a vehicle and generates damping force for damping vibration of the body. It includes: an information acquisition unit that acquires information on a sprung speed and sprung acceleration of the vehicle; a bounce target value computation unit that computes a bounce target value for controlling the vehicle's bounce orientation based on the sprung speed; and a driving control unit that controls driving of the actuator with a control target load which is based on the bounce target value.

Abstract: Provided is an electric suspension device including an electromagnetic actuator that is provided between a body and wheel of a vehicle and generates damping force for damping vibration of the body. It includes: an information acquisition unit that acquires information on a wheel speed and a sprung speed of the vehicle; an estimation unit that estimates a stroke speed of the actuator based on the wheel speed; a determination unit that determines whether a wheel slip has occurred; and an orientation control unit that performs orientation control of the vehicle based on the sprung speed and the estimated stroke speed. When a wheel slip occurs, the orientation control unit performs orientation control of the vehicle based on a fixed stroke speed whose direction is the same as a direction of the sprung speed and whose magnitude is set at a predetermined fixed value, instead of the estimated stroke speed.

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.
