A method for operating an internal combustion engine, in particular of a motor vehicle, in which fuel is injected either in a first operating mode during a compression phase, or in a second operating mode during an intake phase, directly into a combustion chamber. In both operating modes, the fuel mass injected into the combustion chamber is controlled and/or regulated as a function, among other things, of a calculated reference torque to be delivered by the internal combustion engine. A true torque delivered by the internal combustion engine and a permissible torque are determined; and the true torque is compared to the permissible torque.

[ What is claimed is:] [1.]1. A method for operating an internal combustion engine, comprising the steps of:in one of a first operating mode and a second operating mode, injecting a fuel mass directly into a combustion chamber, the first operating mode being during a compression phase, the second operating mode being during an intake phase;calculating a reference torque to be provided by the internal combustion engine;in the first and second operating modes, controlling the fuel mass injected into the combustion chamber as a function of the calculated reference torque;determining an actual torque provided by the internal combustion engine, wherein the actual torque is determined as a function of at least one of the fuel mass which is combusted and a combusted oxygen mass;determining a permissible torque; andcomparing the actual torque with the permissible torque.
