Abstract:
1. A method for identifying a driving resistance of a motor vehicle having at least one drive train with a transmission, comprising the steps of: recording values of control and/or state variables of the motor vehicle during a driving state of the motor vehicle when a control route is covered, adapting, using a controller of the motor vehicle, parameters of a vehicle model and/or a model of an area surrounding the motor 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 model of the surrounding area, wherein the parameters of the vehicle model and/or the model of the surrounding area are adapted on the basis of a distinction between driving states of the motor vehicle, wherein the driving states comprise at least two of driving states of a closed drive train with a positive drive torque, a driving state of a closed drive train with engine overrun, and a driving state with an open drive train.
