Abstract
A method of controlling engine torque according to transmission hydraulic pressure is performed by an engine torque control system of a vehicle. The method includes connecting an engine torque converter to an engine and an automatic transmission of the vehicle, calculating a required turbine torque after confirming an engine torque control condition, deriving and storing a value of turbine torque factor learning through turbine torque factor learning according to shift type and shift time, converting the stored value of turbine torque factor learning into an engine torque control value, and requesting the engine torque control value to be applied to engine output, by an engine torque controller during shifting of the automatic transmission, so that a new turbine torque calculation is performed through a hydraulic pressure reference at the beginning of physical shifting, thereby preventing a shift shock and transmission damage caused by unreasonably excessive or insufficient engine torque.
