Abstract

In a method for operating an internal combustion engine, in particular of a motor vehicle, the internal combustion engine is controlled by at least one drive variable, and an instantaneous torque output by the internal combustion engine is determined from a performance variable of the internal combustion engine that differs from the drive variable. To determine the instantaneous torque, an exhaust-gas temperature of the internal combustion engine is used as performance quantity that differs from the drive variable.
