Patent ID: 8744730

Claim:
A method for controlling an engine braking device ( 16 ) of an internal combustion engine ( 10 ) of a motor vehicle during an up-shift process of a transmission device ( 26 ) connected to the internal combustion engine ( 10 ), the engine having a first and a second cylinder bank ( 12 a , 12 b ), an engine braking device ( 16 ) acting selectively on the first and the second cylinder banks ( 12 a , 12 b ) for independently engaging or disengaging braking operation of the individual cylinder banks, the method comprising the steps of: a) sensing an up-shift process demand; b) blocking the fuel supply to the first cylinder bank ( 12 a ) of the internal combustion engine ( 10 ) and simultaneously c) putting the first cylinder bank ( 12 a ) into braking mode by means of an engine braking device ( 16 ) acting on the first cylinder banks ( 12 a ); d) and, at the same time, increasing the fuel supply to the second cylinder bank ( 12 b ), so as to compensate for the power loss of the first cylinder bank, e) disengaging a gear of the transmission device ( 26 ) and concurrently f) blocking the fuel supply to the second cylinder bank ( 12 b ) for a rapid slow down of the engine to a predetermined speed permitting upshifting, and re-powering all the cylinders.
