A predefined operating strategy permits a predefined operating mode of the motor vehicle. A first operating variable value of the operating mode and/or one additional variable value, which is independent of the operating mode are sensed and one estimated value is determined depending thereon, which is representative of one expected value of the one first operating variable of a second operating variable of the operating mode. One predicted value is determined depending on the sensed values of the one first operating variable, the one additional variable, and/or the one determined estimated value. The predicted value represents an expected operating state and is compared with one predefined comparison value, which is representative of one predefined operation state. The operating strategy is set as a function of the comparison and of the at least one estimated variable in such a way that the predefined operating state is as far as possible avoided.
