Abstract

When controlling an engine provided with Variable Turbine Geometry (VTG), the VTG is closed to a maximally acceptable closed position without endangering the VTG when performing an up-shift. The VTG is kept in such a position during the gear shift which, allows for a quick retardation of the engine speed.
