The present invention relates to method and a device for controlling <strong>the</strong> drive unit <strong>of</strong> a vehicle are<br />

provided, setpoint variables and characteristic variables being received, which represent <strong>the</strong> way<br />

characteristic variables are coordinated independently from one ano<strong>the</strong>r and one <strong>of</strong> <strong>the</strong> variables is<br />

selected, on which <strong>the</strong> control <strong>of</strong> <strong>the</strong> drive unit is based. In a convertor, <strong>the</strong> selected setpoint<br />

selection variable and characteristic variable are converted into control signals, <strong>the</strong> control signals<br />

being selected on <strong>the</strong> basis <strong>of</strong> <strong>the</strong> setpoint selection variable and <strong>the</strong> characteristic variable,<br />

optionally considering fur<strong>the</strong>r operating variables, for example, <strong>the</strong> operating states <strong>of</strong> <strong>the</strong> drive<br />

unit.<br />
