摘要: A method for controlling a driveline having a transmission clutch includes locking the clutch before a driveline lash crossing occurs; maintaining a locked clutch during the lash crossing; after the lash crossing occurs, increasing a clutch capacity at a slower rate than a driveline twist torque rate; and after the lash crossing occurs, producing clutch slip by controlling engine torque and clutch capacity such that engine torque exceeds clutch capacity.

摘要: A method for controlling speed of an input shaft to a hydraulically actuated clutch that includes a hydraulic balance dam volume includes determining a limit speed of the input shaft that varies as a function of time during a predetermined period after the clutch starts rotation and that causes a servo piston for actuating the clutch to move toward an engaged position, rotating the input shaft during the period, limiting a speed of the input shaft during said period to a determined limit speed corresponding to a current time after beginning the period, and allowing the speed of the input shaft to increase to a speed greater than the determined limit speed after expiration of the period.
