摘要： According to a preferred embodiment of the present invention, a clutch is applied when the vehicle comes to a stop. The application of this clutch locks the output shaft with energy stored therein. When the shift selector is then moved to the park position, the clutch releases the stored energy in a controlled manner by slipping the clutch plates. The controlled slipping reduces the noise as the park pawl tooth contracts an output gear tooth.

摘要： In an automatic transmission, clutch-to-clutch powered downshifting is controlled by filling the on-coming clutch at a low pressure while ramping down the off-going clutch pressure until turbine speed is pulled up due to off-going clutch slippage, and then increasing the off-going pressure stepwise to compensate the change from static to dynamic coefficients of friction. Then the on-coming pressure is gradually ramped up and a closed-loop profile control period starts wherein the slip speed of the on-coming clutch is measured and controlled to a slip speed profile by controlling the off-going clutch pressure. When synchronization of the on-coming clutch is first detected, a closed-loop sync control period starts wherein the off-going pressure is controlled to minimize the slip and the on-coming pressure is ramped up at a steeper rate to begin clutch engagement during the sync control period. Adaptive control is accomplished for the initial on-coming pressure by an iterative process which decreases that pressure stepwise until flare occurs and then increases the pressure to stop the flare and repeating the changes in smaller steps to approach the flare condition. Initial off-going pressure is modified when early slip or late slip of the off-going pressure is detected. A modification of off-going pressure step value is effected when the final pressure in the closed-loop period is greater or smaller than the initial pressure. The modifications are targeted to fully correct the respective conditions.

摘要： A dynamic model that is configured to produce a lockup clutch command as a function of a plurality of torque converter operating parameters is continually solved and the lockup clutch command is asserted to control engagement of the lockup clutch. A profile of one of the plurality of torque converter operating parameters is selected and is configured, when inserted into the model in place of an actual value thereof, to result in an intersection of rotational speeds of the pump and the turbine over time. Deceleration of the pump is monitored after asserting the lockup clutch command and a maximum deceleration of the pump is determined therefrom. The selected profile is temporarily held constant if the monitored deceleration of the pump rises at least a threshold value above the maximum deceleration of the pump.

摘要： A clutch control system comprises a clutch torque determination module and a clutch pressure control module. The clutch torque determination module determines a desired torque value for a torque converter clutch (TCC) based on a torque output of an engine, a pump torque value for a pump integrated with a torque converter, a desired engine acceleration, and an inertia value of the engine. The clutch pressure control module selectively controls pressure applied to the TCC based on the desired torque value.

摘要： A process for learning the pressure and volume characteristics for a given torque-transmitting mechanism is established on the final assembly line wherein a powertrain incorporating the desired transmission learning is installed within a vehicle. During the test process, the vehicle speed is generally maintained at Idle and the vehicle shift mechanism is maintained in Park, thereby mechanically locking the transmission output shaft. The torque-transmitting mechanisms to be learned are then engaged and disengaged in a predetermined sequence and the volume of the torque-transmitting mechanisms and the pressure characteristics of the controlling solenoid are learned.
