A method and a device for controlling a drive unit are provided, which allow for a reproducible load reversal damping. For this purpose, a setpoint value for an output variable of the drive unit is limited so that an overrun fuel cutoff of the drive unit is prevented. A limiting value for the setpoint value for the output variable is formed as a function of a loss value of the drive unit.

Method and device for controlling a drive unit

A method and a device for controlling a drive unit which allow an improved transition between idle regulation and drive unit propulsion are provided. A setpoint value for an output variable of the drive unit is predefined, it being possible to modify the setpoint value as a function of at least one reducing request and as a function of at least one load to be compensated for. The ratio of a first priority request for the modification of the predefined setpoint value as a function of the at least one load to be compensated for to a second priority request for the modification of the predefined setpoint value as a function of the at least one reducing request may be varied for different drive unit operating states.

A method for controlling a drive unit of a vehicle which allows a comfortable compensation of the torque requirement of ancillary components. In this method, torque losses are compensated in a steady-state manner in an overrun and an acceleration operation. The steady-state compensation of the torque losses in overrun operation is weighted by a first weighting factor. The first weighting factor is raised in a linear manner when the drag torque decreases in amount, until acceleration operation is reached.

Method of controlling a drive unit of a motor vehicle

The method and apparatus () control a drive unit () with an internal combustion engine (), so that changes of an output variable of the drive unit () during load change are limited. The method includes formulating a desired behavior of the output variable for the load change; changing the desired behavior of the output variable by changing an air supply of the internal combustion engine and forming at least a first preliminary value for adjusting the output variable by filtering the desired behavior according to an inertia of an air system for the air supply of the internal combustion engine.
