エンジン制御装置
Document Type and Number:
Japanese Patent JP7207253
Kind Code:
B2
Abstract:
To provide highly accurate feed pressure control without installing a sensor for detecting a feed pressure.SOLUTION: An engine control device performs: estimation processing S300 of acquiring motor voltage V, a motor current I, a motor rotation number N, a tank temperature T and a fuel consumption amount Q and calculating a value of a feed pressure P satisfying a relation of a formula (1) for those acquired values as a value of an estimated feed pressure Pe; and an operation processing S400 of operating supply power of a motor in order to reduce deviation of the estimated feed pressure Pe relative to a target feed pressure Pt.SELECTED DRAWING: Figure 2
