Method and Device for Operating a Motor Vehicle
First Claim
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 one of values of 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,determining at least one estimated value, which is representative of at least one anticipated value of the at least one first operating mode variable or at least one second operating variable of the predefined operating mode, as a function of at lest one of the values of the at least one first operating variable and the values of the at least one additional variable,determining at least one prediction value, which is representative of an anticipated operating state 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 operating state of the motor vehicle,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 operation state.

Abstract
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.
