Abstract
An engine control system includes an engine that outputs a rotation of a crankshaft through a torsional damper; a calculation portion that calculates a value of engine torque based on an angular acceleration of the crankshaft and a moment of inertia of the crankshaft; and a correction portion that calculates a correction value based on a torsional angle of the torsional damper, and corrects the calculated value of the engine torque using the correction value.
