Title: METHOD FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE HAVING AN ENGINE AND A TURBOCHARGER ASSEMBLY AND HAVING A TRANSMISSION; CONTROL DEVICE AND INTERNAL COMBUSTION ENGINE
Abstract:
The invention relates to a method for controlling an internal combustion engine (1000) having an engine, a turbocharger assembly comprising a main turbocharger and a shift turbocharger for the engine, a gear stage of the transmission being shifted as a function of a threshold value of a rotational speed parameter. According to the invention, a vitality signal indicating the vitality reserve of the internal combustion engine is signaled and a down-shift threshold value of a rotational speed parameter for a gear stage is maintained, depending on the vitality signal, or is reduced to a deceleration threshold value that is lower than the down-shift threshold value.
