Abstract

The invention relates to a method for selecting a gear position of an automatic vehicle transmission with at least one forward gear position and a reverse gear position, in the case of which, at defined operating conditions, a shifting operation from the forward gear position into the reverse gear position or vice versa is ignored. The object of avoiding faulty operations when operating an automatic transmission and increasing the driving comfort is achieved in that the shifting operation is carried out up to a defined first speed of the vehicle, in that, in a speed range of the vehicle between the first and a second speed, during the shifting operation, only a neutral gear position is engaged, and in that the shifting operation is ignored above the second speed.
