发明名称 METHOD AND APPARATUS FOR ESTIMATING CLUTCH FRICTION COEFFICIENT
摘要 A method is provided for estimating a transmissibility of a clutch in a vehicle powertrain, which includes, but is not limited to cutting off fuel supply of an engine driving a first side of the clutch, setting a clutch pressure between first and second sides of the clutch to a positive value at which there is a non-zero difference between angular accelerations at the first and second sides of the clutch, and deriving the estimated transmissibility from a deviation between the angular acceleration difference and an angular acceleration caused by a drag torque of the engine.
