Publication number: 20100179026Abstract: A method of operating a friction plate clutch includes activating a clutch control mechanism to engage the friction plate clutch, and engaging a holding clutch. The clutch control mechanism is then deactivated, rendering it unable to maintain engagement of the friction plate clutch. The holding clutch is used to retain engagement of the friction plate clutch. One embodiment of the method uses a wedge clutch as the holding clutch, and another embodiment uses a one-way bearing clutch. The clutch control mechanism may be a hydraulic clutch control. A latching clutch assembly includes a friction plate clutch movable between an engaged and a disengaged position. A bearing clutch is operatively coupled to the friction plate clutch and has a locked and a released position. The locked position is configured to oppose movement of the friction plate clutch from the engaged position to the disengaged position.Type: ApplicationFiled: January 12, 2009Publication date: July 15, 2010Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Edwin T.
