Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2016118138
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress the occurrence of an error in a calculation value resulting from a correlation with a drive condition parameter possessed by torque when calculating a torque variation.SOLUTION: An ECU of an internal combustion engine comprises torque acquisition means, torque variation calculation means, and error removal means. The torque acquisition means measures torque at each cycle on the basis of in-cylinder data within one cycle which is detected by an in-cylinder sensor, and acquires a plurality of torque measurement values. The torque variation calculation means calculates a torque variation rate at each drive condition on the basis of a relationship between a drive condition parameter of the internal combustion engine and an average value of the torque measurement values, and a relationship between the drive condition parameter and the standard deviation of the torque measurement values. The error removal means removes a variation amount of torque resulting from a correlation between the drive condition parameter and the torque measurement values, when calculating the torque variation rate.SELECTED DRAWING: Figure 3
