Adjusting Clutch Slip Based on Sensed Parameter of Transmission Shaft to Control Vehicle NVH

摘要

A vehicle powertrain includes a transmission and a clutch. The slip of the clutch is adjusted to a predefined target where a sensed parameter of a shaft of the transmission corresponds to a specified noise, vibration, and harshness (NVH) level in the powertrain. The sensed parameter of the transmission shaft may be one of acceleration, speed, and torque of the transmission shaft. The transmission shaft may be one of the input shaft and output shaft of the transmission.
