Method for controlling powertrain of vehicle

Abstract

A method of controlling a powertrain of a vehicle includes determining, by a controller, whether or not a transmission is shifting and, if the transmission is shifting, the type of shifting, selecting a predetermined control matrix according to whether or not the transmission is shifting and the type of shifting, calculating a required torque of a transmission component to be controlled based on the selected control matrix, calculating a hydraulic control pressure to implement the required torque of the transmission component to be controlled, and controlling the transmission component to be controlled using the calculated hydraulic control pressure, wherein the control matrix is calculated using correlation equations of angular velocities, angular accelerations, moments of inertia, and torques of powertrain components, and boundary conditions according to the state of the transmission.
