  "textContent": "In an engine torque calculation method, basic engine torque TQb is calculated based on an engine rotational speed Ne and a fuel injection amount Q (step 120), and the basic engine torque TQb is corrected using a predetermined parameter (e.g., an intake air amount Q) which has an influence on engine torque, whereby engine torque TQact is calculated (step 170). A torque sensitivity coefficient K1 corresponding to an amount of change in the engine torque TQact when the parameter changes by a unit amount is calculated based on the engine rotational speed Ne and the fuel injection amount Q (step 130), and the engine torque TQb is corrected using the torque sensitivity coefficient K1 (step 160).",
