A procedure for controlling a drive unit of a vehicle has motor-adjusting parameters determined in accordance with at least one default value, whereby the motor-adjusting parameters serve to adjust the default value. With the determination of the motor-adjusting parameters, optimization criteria are considered which change during a travel cycle according to external and/or internal influences. The optimization criteria are a minimal consumption or maximum efficiency, least emission, greatest heat development, least noise development and/or greatest dynamics possible. A control unit is provided to control the drive train of the vehicle that controls the drive train in accordance with optimization criteria. Es werden ein Verfahren und eine Vorrichtung zur Steuerung einer Antriebseinheit eines Fahrzeugs vorgeschlagen, bei welcher zur Motoroptimierung Optimierungskriterien vorgegeben werden, die abhängig von internen und/oder externen Einflußgrößen während eines Fahrzyklusses verändert werden. Bei der Bildung von Motorstellgrößen auf der Basis eines Vorgabewertes werden diese sich verändernden Optimierungskriterien berücksichtigt.
