(54) Torque calculation method for engine


(57) A torque calculation method for an engine (100) connected to an automatic transmission (300), wherein when a predetermined first condition is satisfied, fuel supply to the engine (100) is stopped; and when a predetermined second condition relating to the automatic transmission (300) is satisfied, stop of the fuel supply is prohibited, the torque calculation method being characterized by comprising:
calculating first engine torque based on a rotational speed of the engine;
determining whether stop of the fuel supply is being prohibited; and
setting the first engine torque to torque for a case in which the fuel supply is stopped, and calculating second engine torque which is used for control of the automatic transmission, based on the first engine torque, in a case where stop of the fuel supply is being prohibited.
