摘要： A method for controlling a clutch assembly includes controlling an actual clutch fill pressure using open-loop pressure controls when an active fill phase is detected, and using closed-loop pressure controls when the active fill phase is complete or when an overfill condition is detected. The method supplies the actual clutch pressure according to a second set of open-loop pressure controls when a step in commanded clutch pressure is detected. The method monitors a fill pressure and time during the step, and applies the clutch pressure according to the closed-loop pressure controls when either value equals a corresponding threshold value. A clutch assembly has a piston for compressing clutch disks to initiate a shift event, an algorithm for controlling the shift event, and a sensor for determining an actual clutch pressure during the shift phases. The algorithm switches between closed-loop and open-loop pressure controls in response to different shift phases.

摘要： A system and method for detecting vehicle movement based on the measurement of the torque value on a vehicle drivetrain is disclosed. The system includes a torque sensor for measuring the torque on a vehicle drivetrain. This measured torque is utilized by a control module, with various other measured vehicle parameters, to determine if the conditions are such that vehicle movement may occur or has already begun. Possible vehicle movement is indicated when either the measured torque value exceeds a threshold value and changes towards zero, or big noise spikes are present in the torque sensor output signal.

摘要： An adaptive shift learn control system for rapidly updating an adaptive shift system that regulates shifting of a transmission includes first and second clutches and a control module that cycles the first clutch between an ON state and an OFF state while the second clutch is in a full OFF state. The control module monitors a parameter of the transmission during the cycling, calculates a clutch characteristic based on the parameter and updates the adaptive shift control system based on the clutch characteristic.
