A method for carrying out a plausibility check of a first driver input sensor with regard to a second driver input sensor which is different from the first driver input sensor of a motor vehicle includes the first and the second driver input sensors each monitoring interventions of a driver in a brake pedal or an accelerator pedal, or a steering wheel, or a selector lever of the motor vehicle, the measuring signals of the first and the second driver input sensors being detected and redundantly evaluated independently of one another in a first functional module and a second functional module which is independent of the first functional module, and the two evaluations being compared to one another.
