Title:
制御装置、制御方法及びプログラム
Document Type and Number:
Japanese Patent JP7445564
Kind Code:
B2
Abstract:
A control device according to the present invention includes: a prediction unit for predicting a load variation amount; a first derivation unit for deriving a first energy loss amount in a first method for compensating the load variation amount by varying a fuel injection amount to a main engine so as to adjust a power generation amount; a second derivation unit for deriving a second energy loss amount in a second method for compensating the load variation amount by varying a charge amount to an accumulation unit or a discharge amount to a motor; a comparison unit for comparing the first energy loss amount with the second energy loss amount; and a control unit for varying the fuel injection amount to the main engine according to the first method when the first energy loss amount is less than the second energy loss amount, and varying the charge amount or the discharge amount of the accumulation unit according to the second method when the first energy loss amount is equal to or more than the second energy loss amount The present invention can improve energy efficiency of an electric hybrid propulsion system.
