摘要： A system and method for controlling double transition shifts in an automatic transmission having multiple gear sections. During a double transition shift, the system performs simultaneous closed loop control of the primary oncoming clutch in the primary gear section and the secondary off-going clutch of the secondary gear section. Before the input shaft of the secondary gear section is fully pulled down or the secondary off-going clutch becomes overheated, the system switches closed loop control of the input shaft to the secondary on-coming clutch of the secondary gear section. The system utilizes model-based calculations to determine the initial clutch pressure settings when a clutch enters closed loop control.

摘要： A dynamic model is stored in memory that defines torque transmitted by the lockup clutch as a function of a plurality of torque converter operating parameters. A lockup clutch command is asserted to control engagement the lockup clutch, and thereafter a number of the plurality of torque converter operating parameters are monitored. A profile is selected of one of the plurality of torque converter operating parameters, and the profile is configured to result in an intersection of rotational speeds of the pump and the turbine over time when inserted into the model along with the monitored values of the number of torque converter operating parameters. The model is continually solved over time using the selected profile and the monitored operating parameters to produce transmitted torque values, and the lockup clutch command is modified based on the transmitted torque values.

摘要： In an automatic transmission, clutch-to-clutch closed throttle downshifting is controlled by filling the on-coming clutch at a maximum pressure command for a set period while commanding the off-going clutch pressure to a low value and exhausting the off-going clutch before the end of the fill period. At the end of the fill period the on-coming pressure is set to an initial value and then ramped up until turbine speed is pulled up due to off-going clutch slippage. Then a closed-loop profile control period starts wherein the slip of the on-coming clutch is measured and controlled to a slip profile. When synchronization of the on-coming clutch is detected, maximum pressure is commanded. Parameters for controlling the quality of a shift such as on-coming clutch initial pressure and on-coming clutch fill time are automatically adjustable during vehicle use to correct shift aberrations which degrade shift quality.

摘要： A method and system for managing accumulator effects during engagement of a lockup clutch of a torque converter includes selecting a pump speed profile that reduces a rotational speed of a pump of the torque converter from an initial value to a rotation speed of a turbine of the torque converter. A pump acceleration profile is determined based on the pump speed profile. Engagement of the lockup clutch is controlled as a function of an inertia of an engine associated with the torque converter, a torque applied by the engine to the pump, the rotational speed of the turbine, the pump speed profile, and the pump acceleration profile.
