Document Type and Number:
Japanese Patent JP6639434
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To properly calculate a suction air amount sucked into an internal combustion engine.SOLUTION: In an ECU 100 for controlling an internal combustion engine having an airflow sensor for detecting a suction air amount, and a fuel injection valve for injecting fuel, the ECU comprises: a sensor value acquisition part 301 for acquiring a sensor value of the airflow sensor at an acquisition time point at each prescribed acquisition cycle; a sensor information storage part 302 for storing a sensor value which is acquired by the sensor value acquisition part 301, and storing it in a storage part 303 by making it associated with an acquisition time of the sensor value; and an air amount calculation part 306 for calculating the suction air amount in a prescribed integration period corresponding to a calculation cycle and having the same time width as that of the calculation cycle on the basis of the sensor value and the acquisition time at a calculation time point at each prescribed calculation cycle which is longer than the acquisition cycle.SELECTED DRAWING: Figure 2
