液压控制装置
摘要：
本发明提供一种液压控制装置，其在向控制对象部供给油的供给路和自上述控制对象部排出油的排出路这两条油路中的至少任一条油路中设有控制阀，该控制阀基于上述控制对象部的实际液压和上述控制对象部的目标液压之间的偏差被控制电流，从而向上述控制对象部供给与该电流相应的量的油或自上述控制对象部排出与该电流相应的量的油，其中，该液压控制装置构成为：基于上述偏差求出使上述实际液压与上述目标液压一致所需的必要油量，并基于上述控制阀的电流值和流量之间的关系求与上述必要油量对应的电流值。
摘要（英）：

A hydraulic control device in which a supply path for supplying oil to a control object and/or a discharge path for discharging oil from the control object is provided with a control valve, the electric current of which is controlled on the basis of the deviation of the actual oil pressure of the control object from the target oil pressure for the control object and which supplies oil to the control object or discharges oil from the control object in an amount corresponding to the electric current. The device is configured so that the oil volume necessary for matching the actual oil pressure to the target oil pressure is determined on the basis of the deviation and the electric current corresponding to the necessary oil volume is determined on the basis of the relationship between the control valve electric current and the flow rate.
