Abstract
A method for optimizing vehicles and engines that are used for driving such vehicles includes the steps of taking measurements during real operation of the vehicle on the road or on a roller-type test stand, or the engine on an engine test stand; parameterizing a simulation model representing the vehicle or the engine so as to be able to arithmetically determine a prediction about the measured values obtained by means of the measurements; simulating the vehicle by using the simulation model, additionally calculating at least one drivability index (DR) which results from several measured values based on an empirically determined function and which indicates the drivability of a vehicle in a specific driving mode; and optimizing the settings of the vehicle during the simulation, at least one drivability index (DR) being input into the target function or the fringe conditions of the optimization process.
