摘要： A system and method for providing TCC control and/or transmission gear shift control by considering the rate of change of the accelerator pedal or throttle position. The method determines whether the rate of change of the throttle position exceeds a predetermined positive rate of change or a predetermined negative rate of change and, if so, releases the TCC to provide TCC control. Alternatively, or additionally, the method can provide a transmission gear down-shift or up-shift depending on which direction the throttle position is changing. Once the TCC and/or gear shift control has been initiated, the method can start a timer and then return to normal TCC and/or gear shift control after the timer has expired. The TCC and/or gear shift control can also return to normal if the rate of change of the throttle position indicates that the throttle is being returned to its previous position.

摘要： A method is provided for controlling engagement of a clutch which carries torque before, during and after a shifting event in a transmission which is connected to a throttle-controlled engine. The method includes providing a feed forward input command which increases as the engine torque increases and decreases as the engine torque decreases. A feed-back input command is provided as a function of the error between measured clutch slip and a reference slip profile. The feed-forward input command and feed-back input command are summed to provide a clutch control command for controlling engagement of the clutch before, during and after the shifting event to allow a desired amount of clutch slip to damp excitation of the transmission.

摘要： A powertrain has an engine, torque converter, and planetary transmission that includes an input shaft, an output shaft, two simple planetary gear sets, rive rotating torque transmitting mechanisms (clutches) and one stationary torque transmitting mechanism (brake). The planetary gear sets are interconnected with both a permanent interconnection and a selective interconnection. A first member of a first of the planetary gear sets is continuously connected with the output shaft and a first member of the second planetary gear set is continuously connected with a stationary portion of the transmission. Two of the clutches are operable to selectively connect the input shaft with the second and third members of the first planetary gear set, respectively. A third of the clutches is connectable between the second member of the second planetary gear set and the output shaft. The brake is selectively connectable between the second member of the first planetary gear set and the stationary portion. The third members of the planetary gear sets are continuously interconnected for common rotation. The second members of the planetary gear sets are selectively interconnectable by a fourth of the clutches. The second and third members of the second planetary gear set are selectively interconnectable by a fifth of the clutches. The clutches and brakes are selectively engaged in pairs to provide five forward drive ratios and one reverse ratio and interchanged to provide single transition shifts between the lowest four of the forward drive ratios and a double transition shift between the highest two of the forward ratios.
