Abstract
Official abstract text for this publication.
A method of controlling a clutch for vehicle may include determining, by a controller, raised offset engine torque, when engine torque is raised to a reference torque or more in an engine idle state, and controlling, by the controller, the clutch based on the determined offset engine torque.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling a clutch for a vehicle, comprising: determining, by a controller, raised offset engine torque, when engine torque is raised to a reference torque or more in an engine idle state; and controlling, by the controller, the clutch based on the determined offset engine torque. 2. The method according to claim 1 , further comprising, prior to the determining of the raised offset engine torque: judging whether or not conditions for entry calculation are satisfied through the engine idle state, an engine cranking maintenance time, a clutch release state, and a cooling water temperature. 3. The method according to claim 1 , wherein, in the determining of the raised offset engine torque, the offset engine torque is determined by a function representing relations with engine torque, engine angular acceleration, engine rotary inertia and clutch torques. 4. The method according to claim 1 , further comprising, after the determining of the raised offset engine torque: judging whether or not at least one of an absolute value of an engine speed variation and an absolute value of an engine torque variation is less than a reference value. 5. The method according to claim 1 , further comprising, after the determining of the raised offset engine torque: judging whether or not an offset engine torque calculation time is maintained to a designated time or more, as the engine torque is raised to the reference torque or more. 6. The method according to claim 1 , wherein, in the controlling of the clutch, clutch torque is controlled based on a mean value of the determined offset engine torque during starting and shifting. 7. The method according to claim 1 , wherein, in the controlling of the clutch, clutch transmission torque characteristics are learned based on a mean value of the determined offset engine torque.
