1. A method for operating a motor vehicle, comprising:

  • predefining an operating strategy for the motor vehicle, wherein the operating strategy permits a predefined operating mode of the motor vehicle,detecting at least a first operating variable of the predefined operating mode and values of at least an additional variable which is independent of the predefined operating mode, including a value of a detected driving style of a driver of the motor vehicle,determining at least one estimated value of an energy requirement or energy availability as a function of the at least one first operating variable and the values of the at least one additional variable, including the value of the detected driving style of the driver,determining at least one prediction value, which is representative of an anticipated charge state of an energy store of the motor vehicle, as a function of at least one of the detected values of the at least one first operating variable, the detected values of the at least one additional variable, and the determined at least one estimated variable,comparing the at least one determined prediction value with at least one predefined comparison value, which is representative of at least one predefined charge state of the energy store,setting the operating strategy as a function of a result of the comparison and as a function of the at least one estimated value in such a way that the motor vehicle is operated in such a way as to avoid the at least one predefined charge state of the energy store.
