Method for terminating a gearshift for an automatic transmission for a motor vehicle wherein at least one positive-locking shifting element is involved

摘要

A method for terminating a gearshift for an automatic transmission for a motor vehicle is provided, wherein a positive-locking shifting element is involved. After the initiation of the gearshift, there is an evaluation of the continuous signals of at least one control unit of the vehicle, which affect the engine torque and thus the turbine speed gradient. Based on the evaluation of the signals, an upcoming change to the turbine speed gradient that exceeds a first predetermined threshold value or falls short of a second predetermined threshold value is detected, and, upon such detection, the gearshift is terminated.

1. A method for terminating a gearshift in an automatic transmission of a motor vehicle, wherein the gearshift requires actuation of a positive-locking shifting element, comprising:
after initiation of the gearshift, evaluating a continuous signal of a control unit of the vehicle to determine changes in turbine speed gradient resulting from changes in engine torque; and based on the evaluation, terminating the gearshift when the continuous signal indicates that turbine speed gradient will exceed a first predetermined threshold value or fall short of a second predetermined threshold value.
