1. A method for continuous torque monitoring of a hybrid drive of an internal combustion engine having an engine control unit and an intrinsically safe electric drive having a control unit, the method comprising: comparing an admissible total torque with a sum of an actual torque of the electric drive and an actual torque of the internal combustion engine; subtracting the actual torque of the electric drive from the admissible total torque in a subtraction stage in the engine control unit of the internal combustion engine; and forming an admissible torque of the internal combustion engine.
