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 the vehicle's sprung speed, pitch rate, and roll rate; a bounce target value computation unit that computes a bounce target value for controlling the vehicle's bounce orientation based on the sprung speed; a pitch target value computation unit that computes a pitch target value for controlling the vehicle's pitch orientation based on the pitch rate; a roll target value computation unit that computes a roll target value for controlling the vehicle's roll orientation based on the roll rate; and a driving control unit that controls driving of the actuator with a control target load which is based on a sum of the bounce, pitch, and roll target values.
