To provide a damping force control device capable of inhibiting a vehicle structure from being complicated for controlling damping force of a shock absorber.SOLUTION: A damping force control device includes: a calculation unit which uses a trained model for inputting thereto a first physical quantity related to a movement of a vehicle other than vertical acceleration of the vehicle and outputting a second physical quantity related to a vertical movement of the vehicle, and thereby estimates the second physical quantity from a measured value of the first physical quantity, and which calculates a target damping coefficient of a shock absorber on the basis of the estimated second physical quantity; and a damping force control unit which controls damping force of the shock absorber on the basis of the calculated target damping coefficient.SELECTED DRAWING: Figure 3

    【課題】ショックアブソーバの減衰力を制御する上で車両の構造が複雑化するのを抑制することが可能な減衰力制御装置を得る。【解決手段】減衰力制御装置は、車両の上下方向の加速度以外の車両の運動に関する第1の物理量を入力して車両の上下方向の運動に関わる第2の物理量を出力する学習済みモデルを利用して、第1の物理量の実測値から第2の物理量を推定し、推定した第2の物理量に基づいて、ショックアブソーバの目標減衰係数を算出する算出部と、算出された目標減衰係数に基づいて、ショックアブソーバの減衰力を制御する減衰力制御部と、を備える。【選択図】図3
