Abstract:
A method for controlling a drive unit of a vehicle, the method comprising the steps of:forming a maximum permissible torque (mizul) for said drive unit in dependence upon one of the following: the position (wped) of an operator-controlled element actuable by the driver and a desired torque (miext) pregiven by at least one external function;forming a corrective value (mioff) considering tolerances in said maximum permissible torque (mizul) for correcting said maximum permissible torque (mizul) in dependence upon the engine rpm and said maximum permissible torque (mizul) and superposing said corrective value (mioff) as an offset value on said maximum permissible torque (mizul);comparing the corrected maximum permissible torque (mizul) to an actual torque (miact) of said drive unit; and,reducing the torque of said drive unit when the actual torque (miact) exceeds said corrected maximum permissible torque (mizul).
