Abstract
A controller performs a rotation angle deriving process that derives a value of the rotation angle of a crankshaft by each specified angle that is smaller than a predetermined angle by performing a Hilbert process on a detection signal from a crankshaft sensor, an angular velocity deriving process that derives an angular velocity of the crankshaft as an engine angular velocity from the value of the rotation angle of the crankshaft by each specified angle, an inertia torque calculation process that calculates an engine inertia torque from the engine angular velocity, a resonance effect torque calculation process that calculates a resonance effect torque, and an engine torque calculation process that calculates a sum of the resonance effect torque and the engine inertia torque as an engine torque that is an output torque of the engine.
