Abstract: A method for operating a motor vehicle includes providing route segments of a route ahead of the vehicle that is most likely to be traveled as well as route parameters associated with the route segments, dividing the route ahead of the vehicle that is most likely to be traveled into sub-segments, optimizing the setpoint speeds at the segment boundaries of the sub-segments with respect to a specified target function, interpolating the setpoint speeds obtained at the positions of the segment boundaries to obtain a characteristic curve of the setpoint speed, and operating the motor vehicle based on a specification of the characteristic curve of the setpoint speed.

Abstract: A method for identifying a driving resistance of a motor vehicle includes the steps of recording values of control and/or state variables of the vehicle during a driving state of the vehicle when a control route is covered, adapting parameters of a vehicle model and/or a model of the area surrounding the vehicle on the basis of the values of the recorded control and state variables, identifying the driving resistance on the basis of the adapted vehicle model and/or the surrounding area model, wherein the parameters of the vehicle model and/or the surrounding area model are adapted on the basis of a distinction between driving states, wherein these driving states include a driving state of a closed drive train with a positive driver demand torque, a driving state of a closed drive train without a positive driver demand torque, and/or and a driving state with an open drive train.
