PROBLEM TO BE SOLVED: To perform proper control even at anti-block brake control, in a suspension control device of a vehicle having a suspension which can variably set an attenuation force, and a control unit which calculates the acceleration of a vehicle in a fore-and-aft direction on the basis of brake fluid pressure detected by a fluid pressure sensor which detects brake fluid pressure, and can control the attenuation force of the suspension by a target attenuation force which is defined on the basis of the acceleration.SOLUTION: A control unit has acceleration calculation means 45 which calculates acceleration on the basis of a normal brake force 51 corresponding to a detection value of a fluid pressure sensor at a normal brake, however, at anti-block brake control, calculates the acceleration on the basis of a prescribed anti-block control brake force 52.SELECTED DRAWING: Figure 5 【課題】減衰力を可変設定可能なサスペンションと、ブレーキ液圧を検出する液圧センサで検出されるブレーキ液圧に基づいて、車両の前後方向の加速度を算出するとともに、その加速度に基づいて定めた目標減衰力で、サスペンションの減衰力を制御可能な制御ユニットとを、備える車両のサスペンション制御装置において、アンチロックブレーキ制御時にも適切な制御を可能とする。【解決手段】制御ユニットは、通常ブレーキ時には液圧センサの検出値に応じた通常ブレーキ力５１に基づいて速度を算出するものの、アンチロックブレーキ制御時には所定のアンチロックブレーキ制御時ブレーキ力５２に基づいて加速度を算出する加速度算出手段４５を有する。【選択図】図５
