Method and arrangement for controlling a drive unit

A method for controlling a drive unit for which at least one measurement signal quantity (U1) having at least one end value is detected with said drive unit being controlled in dependence upon said end value, the method comprising the steps of:

• presetting several signal quantity regions (I to V) for said end value of said measurement signal quantity (U1) with said signal quantity regions (I to V) being assigned respective calibration values (UPWGRES, UPWGUR, UPWGERS, UPWGNOT, UPWGO);
• determining the one of said signal quantity regions (I to V) which said end value of said measurement signal quantity (U1) has reached;
• selecting the calibration value assigned to said one signal quantity region;
• converting said measurement signal quantity (U1) into a relative measurement quantity (wped) on the basis of the selected calibration value;
• and,
• when in a new driving cycle, a measurement signal quantity region is reached in the area of the old calibration quantity, immediately resetting the calibration quantity to this calibration quantity.
