Abstract

A method for plausibilization of an engine control function for an internal combustion engine includes: provision of injection parameters with which an injection of fuel into cylinders of the internal combustion engine is controlled on the basis of a torque that is to be realized; estimation of an actual torque of the internal combustion engine as a function of the injection parameters; and evaluation of the actual torque as a function of the torque that is to be realized, in order to plausibilize the engine control function.
