摘要： A closed loop shift control apparatus and method based on estimated torque in friction elements controls a torque transfer phase when shifting from a low gear configuration to a high gear configuration for an automatic transmission system. When pressure actuated friction elements are selectively engaged and released to establish torque flow paths in the transmission, estimates of torsional load exerted on the off-going friction element are used to predict the optimal off-going friction element release timing for achieving a consistent shift feel. The estimated torque is preferably calculated by using estimated torque signals generated as a function of speed measurements represented either the engine speed and turbine output speed or transmission output speed and wheel speed under dynamically changing conditions.

摘要： A method of operating a transmission with interlocking and friction shifting elements. In or to carry out a gearshift from a currently gear to a target gear, one shifting element is disengaged and another is engaged, and if to carry out a gearshift an interlocking shifting element has to be engaged, the interlocking shifting element is synchronized by partially closing a friction shifting element, with redundancy in the transmission, only if a current speed of the vehicle is lower than a limit value. To monitor for possible malfunction, actuation of the shifting elements and the driving speed are monitored and if, based on the actuation of the shifting elements, it is concluded that there is a redundancy in the transmission, a stored non-actual driving speed is compared with the limit value and if the stored driving speed is higher than the limit value, the redundancy in the transmission is eliminated.

摘要： A method of operating a transmission of a vehicle drive train with at least one drive machine. The transmission is formed with at least one interlocking shift element and a plurality of frictional shift elements in order to obtain various gear ratios. During an engaging process of the interlocking shift element, starting from a disengaged operating condition, in which halves of the interlocking shift element are out of engagement, to an engaged operating condition, in which the shift element halves are interlocked in a rotationally fixed manner, when interlock between the shift element halves is obstructed, a rotational speed difference is produced at least temporarily between the shift element halves, at which the interlock in the area of the interlocking shift element can be engaged. To produce the speed difference between the shift element halves, the transmission capacity of at least one frictional shift element is increased.
