To suppress the deterioration of ride comfort of passengers while improving safety of traffic.SOLUTION: An electric suspension control device 15 for an electric suspension 11 with an electric motor 31, gradually decreases a thrust command of the electric suspension under a predetermined operation condition, and short circuit controls the electric motor when the thrust command is a predetermined value or less. The operation conditions are the detection of a stop notice command of power supply to the electric suspension, the detection of a short circuit command in a measurement upon a collision and a predetermined velocity during deceleration, or the detection of road surface change equal to or more than a predetermined value of a preview sensor.SELECTED DRAWING: Figure 3

    【課題】交通の安全性を向上させながら、乗客の乗り心地の低下を抑制する。【解決手段】発明の電動サスペンション制御装置15は、電動モータ31を有する電動サスペンション11の制御装置であって、所定の動作条件において、電動サスペンションの推力指令を徐々に小さくし、推力指令が所定値以下の時に電動モータを短絡制御する。そして、動作条件は、電動サスペンションへの電力供給の停止予告の指令の検知、衝突時の対策における短絡指令、減速中の所定車速の検出、または、プレビューセンサの所定値以上の路面変化の検知とする。【選択図】図3
