TORQUE ESTIMATION METHOD FOR TRANSMISSION CLUTCH

摘要

A method of estimating a torque of a transmission clutch may include correcting an error by deducing an engine transient torque based on an engine angular velocity measured using a sensor, an engine static torque deduced using a data map, and a load torque depending on a driving load, deducing an engine angular velocity estimation value based on the engine static torque and the engine transient torque, and deducing a clutch torque estimation value depending on a slip in the transmission clutch from a difference between the engine angular velocity estimation value and the measured engine angular velocity.
