Torque calculation method for engine

摘要

A torque calculation method for an engine (100) connected to an automatic transmission (300), wherein torque of the engine (100) is controlled based on first engine torque that is calculated based on a rotational speed of the engine (100); and the first engine torque is corrected so that the rotational speed during idling becomes equal to a predetermined rotational speed, the torque calculation method being characterized by comprising:
calculating second engine torque which is used for control of the automatic transmission (300), based on the first engine torque; and
correcting the second engine torque based on a correction amount of the first engine torque.
