Method for controlling gear definition in an automated stepped gearbox

摘要

A method for controlling the gear release in an automated multi-speed drive in a vehicle drive with a drive motor and a separating clutch positioned between the drive motor and the multi-speed drive that the events "application of a shifting power" and "opening of the separating clutch" are determined dependent on reaching certain vehicle accelerations (agear-release, aclutch-engage). The vehicle acceleration (aveh) decreases at the beginning of the shifting process due to the reduction of the fuel injection quantity (EM) supplied to the drive motor.
