摘要：
A method to control a clutch in a transmission includes monitoring a frequency response of the clutch including monitoring a response repeating one time per revolution of the clutch a response repeating more than one time per revolution of the clutch. A ratio of the response repeating more than one time per revolution of the clutch to the response repeating one time per revolution of the clutch is determined and compared to a first threshold ratio. A likely shudder condition is indicated based upon the comparing.
