Abstract

In a method and a device for operating a drive unit, a first output variable of the drive unit is restricted; a setpoint value of a second output variable of the drive unit is specified; and an actual value of the second output variable of the drive unit is determined. The setpoint value is compared with the actual value, and if it is determined that the actual value does not exceed the setpoint value, then the first output variable is restricted to a first value. If it is determined that the actual value exceeds the setpoint value, then the first output variable is restricted to a second value smaller than the first value.
