Abstract

In a method for controlling an engine braking device of an internal combustion engine of a motor vehicle during an up-shift process of a transmission device connected to the internal combustion engine which includes a first cylinder bank and a second cylinder bank, an engine braking device acting on individual cylinder banks, a fuel supply device acting on individual cylinder banks and a shiftable transmission device, which comprises shiftable gearwheels and an input shaft which can be coupled to a crankshaft of the internal combustion engine by means of a clutch are provided and used during up-shifting to manipulate braking and powering up the cylinder banks and disengaging and up-shifting the transmission for a fast and smooth gear change operations.
