发明名称 ERHÖHUNG DER SPONTANITÄT EINES AUTOMATGETRIEBES
摘要 A method for shifting gears of a transmission of a vehicle, which, during a shift, a first shift element opens and a second shift element closes. To increase the spontaneity and reduce the shifting frequency a downshift from a first gear to a second gear is interrupted without delay and the first gear returned to when an interruption criterion is recognized. The interruption criterion is established when the driver upshifts before a current transmission input speed deviates from a synchronous speed of the first gear or before a time interval, which begins when the speed deviates from the synchronous speed of the first gear, has exceeded a predefined, time-related limit value or before the current transmission input speed has deviated from a synchronous speed of the first gear by a predefined, speed-related limit value or before a pressure of the first shift element falls below a pressure-related limit value.
