To obtain appropriate damping characteristics according to a traveling scene so as to allow for securing excellent riding comfort.SOLUTION: A damper control device (damper control ECU30) includes: a stroke speed calculation unit 312 configured to calculate a stroke speed of a damper; an unsprung mass acceleration calculation unit 314 configured to calculate an unsprung mass acceleration that is input to the damper; and a first control command value calculation part 321 configured to calculate a first control command value derived from a stroke calculated by using, as an input value, the stroke speed; a second control command value calculation part 322 configured to calculate a second control command value derived from an unsprung mass acceleration calculated by using, as an input value, the unsprung mass acceleration; and a damper control part 33 configured to control the damper by referring to the second control command value when the unsprung mass acceleration is a predetermined value or more, and configured to control the damper by referring to the first control command value when the unsprung mass acceleration is less than the predetermined value.SELECTED DRAWING: Figure 2

    【課題】 走行シーンに応じて適切な減衰特性を得ることにより良好な乗り心地を確保できるようにする。【解決手段】 ダンパ制御装置(ダンパ制御ECU30)は、ダンパのストローク速度を算出するストローク速度算出部312と、ダンパに入力されるばね下加速度を算出するばね下加速度算出部314と、ストローク速度を入力値として算出されるストロークに由来する第1の制御指令値を算出する第1の制御指令値算出部321と、ばね下加速度を入力値として算出されるばね下加速度に由来する第2の制御指令値を算出する第2の制御指令値算出部322と、ばね下加速度が所定値以上の場合、第2の制御指令値を参照してダンパを制御し、ばね下加速度が所定値未満の場合、第1の制御指令値を参照してダンパを制御するダンパ制御部33と、を有する。【選択図】 図2
