Abstract

In a method for controlling a drive unit, a driver command value is formed while considering the current transmission ratio and the drive unit is controlled in dependence upon the driver command value. In addition, a predicted driver command value is determined in dependence upon transmission ratios other than the current transmission ratio. In addition, the minimum and maximum possible values are considered in the formation of the driver command value. A correction of the driver command value is undertaken in dependence upon the difference between minimum possible torque and minimum requested torque or between maximum possible torque and maximum requested torque.
