Claim Text:
1. A method of estimating a torque of a transmission clutch, comprising: correcting, by a controller, an error of the torque 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, by the controller, an engine angular velocity estimation value based on the engine static torque and the engine transient torque; deducing, by the controller, 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; and controlling, by the controller, the transmission clutch, using the clutch torque estimation value.
