    Abstract: A vehicle includes an engine, an engine control module (ECM), and a dual clutch transmission (DCT) assembly. The DCT assembly has first and second input clutches, first and second gear sets selectively connected to the engine via the respective first and second input clutches, and a transmission control module (TCM). In executing a launch control method, the TCM receives a launch request, receives an actual engine torque, and determines the inertia and acceleration of the engine. The TCM then calculates a clutch torque for the particular input clutch used for vehicle launch as a function of the actual engine torque and the product of the inertia and the acceleration, compares the calculated clutch torque to the commanded clutch torque, modifies a torque-to-position (TTP) table depending on the comparison result, and transmits a clutch position signal to the designated input clutch to command an apply position extracted from the TTP table.

    Abstract: A method of controlling the performance of a vehicle from a stationary condition includes operating a vehicle powertrain in a creep mode following the disengagement of a driver-operated braking device; and operating the vehicle powertrain in a launch mode following an engagement of a driver-operated acceleration device subsequent to the disengagement of the driver-operated braking device. Operating a vehicle powertrain in a creep mode includes: applying a friction clutch to couple an engine crankshaft of the vehicle powertrain with an input shaft of the transmission; determining a torque command to accelerate the vehicle powertrain at a predetermined rate; providing the torque command to an engine controller to controllably increase the input torque to the transmission; and operating a closed loop engine speed control module to prevent the crankshaft speed from slowing below a predetermined engine idle speed.

    Abstract: A vehicle includes an engine, transmission, engine control module (ECM), and transmission control module (TCM). The transmission includes an input member and an input clutch which selectively connects a crankshaft of the engine to the input member. The TCM identifies a target clutch torque of the input clutch during a creep maneuver of the vehicle, and communicates the identified target clutch torque to the ECM. The ECM maintains engine idle speed at a threshold level through the creep maneuver and a requested launch using the target clutch torque as a feed-forward term. A method includes identifying a target clutch torque of the input clutch during a creep maneuver, and communicating the identified target clutch torque to the ECM. The idle speed is maintained at a threshold level by the ECM through the creep maneuver and a detected launch using the target clutch torque as a feed-forward idle speed control term.

    Abstract: A vehicle includes an engine, a transmission having a position-controlled clutch with a synchronizer sleeve and a synchronizer fork, an input member with an input speed, and an output member with an output speed, and a controller. The controller is programmed to register a slip-away condition when the input speed falls within a calibrated speed band and the output speed remains below a calibrated threshold speed. In response to the registered slip-away condition, the controller records a diagnostic code indicative of the synchronizer sleeve being disengaged, changes an engaged position of the synchronizer sleeve by a calibrated amount to thereby adapt the engaged position, and commands the clutch to disengage and the fork to move to a neutral position after increasing the engaged position. The controller also moves the synchronizer sleeve toward the adapted engaged position and applies the clutch when the synchronizer sleeve attains the adapted engaged position.
