Abstract

In a device for reducing engine torque between the beginning and end of a shift of a transmission in motor vehicles with a control device that detects the beginning of a shift as well as continuously determines the current engine rpm, and calculates in advance the engine rpm anticipated at the end of the shift, the amount of reduction of engine torque between the beginning and end of the shift is regulated in such a manner that a preset engine rpm curve is achieved.
