Method for executing a gearshift in an automatic transmission
Abstract:
A method is provided for executing a gearshift in an automatic transmission with several shifting elements. Upon the execution of the gearshift, a first frictional-locking shifting element is opened and a second positive-locking shifting element is closed. If, upon the execution of the gearshift, an input torque of the automatic transmission is less than a threshold value, after at least partially opening the frictional-locking shifting element and after releasing the positive-locking shifting element, there is a monitoring of whether the positive-locking shifting element is transferred into its end position. If it is then determined that the positive-locking shifting element is not in its end position, a torque transferred by the partially open frictional-locking shifting element initially increases. If, despite the increase in torque transferred by the frictional-locking shifting element, the positive-locking shifting element is not in its end position, the operating pressure of the positive-locking shifting element is then increased.
