Abstract

A method for controlling a gear-shifting process from an initial gear to a target gear in a manual transmission with active interlock. According to the method, the active interlock gear-shifting mechanism includes at least one shifting finger which co-operates with a selector fork, and has a layout geometry including a finger and a cam. The method contains the following steps: the selector fork of the initial gear is brought into a reliable shifting position by a method for compensating errors on the gear shifting mechanism, and/or the selector fork of the target gear is brought into a reliable shifting position a method for compensating errors on the gear shifting mechanism, before the target gear is engaged, when ever a temporarily non-critical gear-shift is to be carried out.
