Abstract

A method and an arrangement for operating a drive unit of a vehicle are suggested. Starting from a driver command torque which is converted into a resulting desired torque while considering additional torques, a correction of the resulting desired torque is undertaken in dependence upon the loss torques, which are not available for the drive. For realizing a negative torque command of the driver, the driver command torque is corrected with the loss torque weighted in dependence upon accelerator pedal position and rpm.
