車両のサスペンションに用いられ姿勢制御を行う油圧シリンダと、該油圧シリンダに供給する油液を蓄圧するアキュムレータと、前記油圧シリンダおよび前記アキュムレータに油液を供給するための油圧ポンプと、前記油圧シリンダに油液を給排するための給排手段と、前記油圧ポンプをアンロードするためのアンロード手段と、前記車両の走行状態に関する情報を検出する検出手段とを備え、前記検出手段の検出に基づいて、前記給排手段を制御して、前記車体の姿勢制御を行うサスペンション制御装置において、
前記アンロード手段は、前記アキュムレータの蓄圧圧力に基づいて、前記油圧ポンプをアンロードし、かつ、前記検出手段の検出に基づいて、前記車両の走行状態が前記油圧シリンダへの油液の供給量が多くなる所定の状態であるとき、前記油圧ポンプをオンロードすることを特徴とするサスペンション制御装置。
A hydraulic cylinder that is used in a vehicle suspension and performs posture control, an accumulator that accumulates hydraulic fluid supplied to the hydraulic cylinder, a hydraulic pump that supplies hydraulic fluid to the hydraulic cylinder and the accumulator, and a hydraulic cylinder Based on the detection of the detection means, comprising: supply / discharge means for supplying and discharging oil, unload means for unloading the hydraulic pump, and detection means for detecting information relating to the running state of the vehicle. In the suspension control device that controls the posture of the vehicle body by controlling the supply / discharge means,
The unloading means unloads the hydraulic pump based on the accumulated pressure of the accumulator, and based on the detection of the detecting means, the running state of the vehicle is the amount of oil supplied to the hydraulic cylinder. The suspension control device characterized in that the hydraulic pump is on-loaded when a predetermined state increases.

前記アンロード手段は、前記アキュムレータの蓄圧圧力が所定の設定圧力となるように前記油圧ポンプをアンロードし、前記検出手段の検出に基づいて、前記車両の走行状態が前記油圧シリンダに油液の供給量が多くなる所定の状態であるとき、前記アキュムレータの設定圧力を高くすることを特徴とするサスペンション制御装置。
A hydraulic cylinder that is used in a vehicle suspension and performs posture control, an accumulator that accumulates hydraulic fluid supplied to the hydraulic cylinder, a hydraulic pump that supplies hydraulic fluid to the hydraulic cylinder and the accumulator, and a hydraulic cylinder Based on the detection of the detection means, comprising: supply / discharge means for supplying and discharging oil, unload means for unloading the hydraulic pump, and detection means for detecting information relating to the running state of the vehicle. In the suspension control device that controls the posture of the vehicle body by controlling the supply / discharge means,
The unloading means unloads the hydraulic pump so that the accumulated pressure of the accumulator becomes a predetermined set pressure, and based on the detection of the detecting means, the running state of the vehicle determines whether oil pressure is applied to the hydraulic cylinder. A suspension control device characterized by increasing the set pressure of the accumulator when the supply amount is in a predetermined state.
