Abstract
A method for operating a parallel hybrid drive train of a vehicle having an internal combustion engine, an electric engine and an output. The electric engine being located in the power drive between the output and the internal combustion engine. A second shifting element is located between the internal combustion engine and the electric engine and a first shifting element between the electric engine and the output. Output torque driving the output can be adjusted according to the transmitting capacities of the first and second shifting elements and according to the input torque of the electric engine and/or internal combustion engine. These adjustments are corrected according to standards derived from divergences found in parameters during operation of the drive train.
