使驱动单元运行的方法和装置
Abstract:
本发明涉及使驱动单元（2），尤其是内燃发动机运行的方法，它具有以下步骤：提供名义功率参数（trqDesEng），用于控制具有名义功率参数（trqDesEng）的驱动单元（2）；对于所提供的名义功率参数（trqDesEng）提供取决于运行点的功率范围的参数，在这些范围里允许驱动单元（2）稳定地运行，因此在取决于运行点的功率范围之间规定了稳态-非许可的功率范围；如果在过渡运行状态下驱动单元（2）的名义功率参数（trqDesEng）的变化要求穿越一种稳态-非许可的功率范围，那么根据一个有关受控制的名义功率（trqDesEngLtd）参数来控制驱动单元（2），其中受控制的名义功率参数（trqDesEngLtd）通过名义功率参数（trqDesEng）的控制来确定，最大持续时间限制于规定的最大持续时间之内，在这最大持续时间期间，控制驱动单元（2）用于在稳态-非许可的功率范围里，提供受控制的名义功率参数（trqDesEngLtd）。
Abstract(English):

The invention relates to a method for operating a drive unit (2), particularly an internal combustion engine, comprising the following steps: - providing a target output specification (trqDesEng) for controlling the drive unit (2) at a target output; - providing a specification of operating point-dependent output ranges for the provided target output specification (trqDesEng) in which a steady-state operation of the drive unit (2) is permissible, whereby an impermissible steady-state output range is defined between the operating point-dependent output ranges; - if in a transition operating mode a change of the target output specification (trqDesEng) for the drive unit (2) requires the impermissible steady-state output range to be crossed, controlling the drive unit (2) using a specification of a guided target output (trqDesEngLtd), wherein the guided target output specification (trqDesEngLtd) is determined by guiding the target output specification (trqDesEng) so that the maximum duration during which the drive unit (2) is controlled within the impermissible steady-state output range to provide the guided target output (trqDesEngLtd) is limited to a specified maximum duration.
