Clutch slip identification systems and methods

摘要

A control system for a transmission of a vehicle includes a first angular rotation module, a second angular rotation module, and a slip module. The first angular rotation module determines a first angular rotation of a first component of the transmission during a predetermined period based on a first signal generated by a first sensor. The second angular rotation module determines a second angular rotation of a second component of the vehicle during the predetermined period based on a second signal generated by a second sensor. The slip module selectively indicates that a clutch of the transmission is slipping based on the first angular rotation and the second angular rotation.

1. A control system for a transmission of a vehicle, comprising:
a first angular rotation module that determines a first angular rotation of a first component of the transmission during a predetermined period based on a first signal generated by a first sensor; a second angular rotation module that determines a second angular rotation of a second component of the transmission during the predetermined period based on a second signal generated by a second sensor; a slip module that, while a gear shift is not occurring, selectively indicates that a clutch of the transmission is slipping based on the first angular rotation and the second angular rotation; and a pressure control module that:
while a gear shift is not occurring, decreases a pressure applied to the clutch in response to the slip module indicating that the clutch is not slipping; andwhile a gear shift is not occurring, increases the pressure applied to the clutch in response to the slip module indicating that the clutch is slipping.
