  "textContent": "To provide a controller for an internal combustion engine which can correct the detection error of the crank angle with good accuracy. A controller for an internal combustion engine corrects an angle interval or a time interval of an angle section by a correction value; estimates a shaft torque of a crankshaft using the physical model equation of a crank mechanism based on a detection value of a gas pressure in an intake pipe and a detected angle; calculates an ideal interval angular speed based on an estimation value of the shaft torque; and changes the correction value so that the detection section angular speed after correction approaches the ideal interval angular speed.",
