The invention relates to methods for optimizing vehicles and engines that are used for driving such vehicles, comprising the following steps: measurements are taken during real operation of the vehicle ( 10 ) on the road or on a roller-type test stand or the engine ( 21 ) on an engine test stand ( 19 ); a simulation model representing the vehicle ( 10 ) or the engine ( 19 ) is parameterized so as to be able to arithmetically determine a prediction about the measured values obtained by means of said measurements; the vehicle ( 10 ) is simulated by using the simulation model ( 11 ), at least one drivability index (DR) being additionally calculated which results from several measured values based on an empirically determined function and indicates the drivability of a vehicle ( 10 ) in a specific driving mode; the settings of the vehicle ( 10 ) are optimized during said simulation, at least one drivability index (DR) being input into the target function or the fringe conditions of the optimization process. |
