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. The bounce target value computation unit has a bounce target load map in which the bounce target value is associated with the sprung speed. The bounce target value computation unit adjusts a width of a dead zone set in the map based on the information on the sprung speed and sprung acceleration.
