Abstract
The invention is directed to a method for controlling the input torque of a transmission mounted downstream of an internal combustion engine during a gear ratio changing operation of the transmission. The input torque is increased or decreased by pregiven measures beyond the value thereof present at the start of the shifting operation in dependence upon mode of shifting present. The method includes performing at least one of the following steps to realize at least one of the measures: actuating a device for changing the geometric characteristics of the exhaust-gas system of the engine; actuating the electromagnetic brake controlling the input torque of the transmission; switching in or switching out ancillary equipment driven by the engine; actuating the intake or exhaust valves of the engine to generate a negative combustion torque; and, if the engine is an engine having externally supplied ignition, advancing the ignition time point of the engine.
