Method for operating a vehicle and driver assistance system

The invention relates to a method for operating a vehicle, comprising the following steps: providing a multidimensional analytical vehicle operating cost function that defines a dependency of a consumption of vehicle drive energy on a driving distance or a driving time lying ahead of the vehicle as well as on multiple control variables, calculating a profile of one control variable of the multiple control variables, whereby the profile minimizes the vehicle operating cost function for the driving distance or for the driving time lying ahead, whereby the remaining control variables are held constant for the calculation of the profile, repeatedly calculating further respective profiles of the multiple control variables, whereby the respective profile of one control variable of the multiple control variables minimizes the vehicle operating cost function for the driving distance or for the driving time lying ahead, whereby for the calculation of the respective profile the control variables are specified according to the previously correspondingly calculated profiles and the remaining control variables are held constant, controlling the vehicle in dependence on the calculated respective profiles of the multiple control variables while the vehicle travels the driving distance or while the driving time elapses. The invention further relates to a computer program product as well as a driver assistance system.
