Abstract
A method for controlling a drivetrain of a motor vehicle is provided. The drivetrain includes, as components, at least an internal combustion engine, an electric drive machine, a clutch and a transmission that can be connected to drive wheels. A control device initiates gear shifts at the transmission based on a wide variety of sensor signals by using a characteristic diagram. In order to ensure an excellent shift quality over long operating periods, a drive torque value Mof the internal combustion engine, which is determined by the control device, can be checked and if necessary corrected in dependence of given conditions by determining the drive torque value Mof the electric drive machine.
