MODE MILEAGE CALCULATION DEVICE FOR VEHICLE MOUNTED WITH INTERNAL COMBUSTION ENGINE AS POWER SOURCE AND MODE MILEAGE CALCULATION METHOD

摘要

PROBLEM TO BE SOLVED: To accurately calculate a mode mileage of a vehicle mounted with an internal combustion engine as a power source.;SOLUTION: A mode mileage calculation device: converts an evaluation mode into time-series data which shows operation conditions (an engine rotation speed and generated torque) of an internal combustion engine; reads out a steady mileage from a steady mileage map according to the converted time-series data; corrects the steady mileage read out from the map on the basis of a torque change speed; and calculates a mode mileage using the corrected mileage. Thus, the mode mileage calculation device can incorporate effects of the operation conditions of the internal combustion engine which change from moment to moment on the mileage into a calculation of the mode mileage and thereby improving calculation accuracy thereof.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
