Patent ID: 8628451

Claim:
Method for clutch control for a transmission, comprising: deactivating a first clutch associated with a target operating mode; activating an oncoming clutch associated with the target operating mode and deactivating an off-going clutch associated with an initial operating mode; and then reactivating the first clutch, comprising: monitoring rotational speeds of clutch elements of the first clutch, the clutch elements coupled to first and second torque actuators, wherein the first and second torque actuators are presently rotationally independent, commanding a control speed profile for the first torque actuator, generating a speed profile of the first clutch approaching zero speed, generating a control speed profile for the second torque actuator corresponding to a speed of the first torque actuator, the speed profile of the first clutch, and an output speed of the transmission, controlling a speed of the second torque actuator using the control speed profile for the second torque actuator and coincidently coordinating outputs of the second torque actuator and a third torque actuator to generate an output torque to the output member that is responsive to an output torque request, monitoring a speed of the first clutch, and activating the first clutch when the speed of the first clutch is zero.
