Abstract
A method for the control of a bi-directional overrunning clutch assembly (10) disposed within a vehicle transmission, including the steps of initiating a drive function control routine (112) within an electronic control unit and sensing the commanded gear ratio within the transmission. The method steps further include determining whether a first gear function (132) should be initiated based on the commanded gear ratio and determining whether a second gear function (150) should be initiated based on the commanded gear ratio. The method also includes sensing whether the reverse engagement members (24B) and the forward engagement members (24A) of the bi-directional clutch (10) are engaged when neither the first gear function (132) nor the second gear function (150) are initiated.
