Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2023/199532
Kind Code:
A1
Abstract:
Provided is a control device for an internal combustion engine that can accurately correct an error in detecting a crank angle. A control device (50) for an internal combustion engine corrects an angle interval (Δθd) or a time interval (ΔTd) of an angle section with a correction value (Kc), estimates a shaft torque (Tcrke) of a crank shaft using a physical model formula of a crank mechanism on the basis of a detection value (Pind) and a detection angle (θd) of a gas pressure inside a suction pipe, calculates an ideal section angular speed (ωid) on the basis of the estimated value (Tcrke) of the shaft torque, and changes the correction value (Kc) so that a detection section angular speed after correction approximates the ideal section angular speed (ωid).
