Abstract: An engine command override may occur when a diesel particulate filter (DPF) requires regeneration. The need for regeneration may be indicated by regeneration level. The engine may be operated in a normal mode when the DPF regeneration level is below a regeneration level threshold, wherein the engine command is based on the throttle input. Additionally, the engine may be operated in an override mode when the DPF regeneration level is above a regeneration level threshold and the engine is operating in the idle state, wherein the engine command is based on a predetermined throttle regeneration setting.

Abstract translation: 当柴油机微粒过滤器（DPF）需要再生时，可能会发生发动机指令超驰。 可以通过再生水平来指示再生的需要。 当DPF再生水平低于再生水平阈值时，发动机可以在正常模式下操作，其中发动机命令基于油门输入。 此外，当DPF再生水平高于再生水平阈值并且发动机正在空转状态下时，发动机可以在超控模式下操作，其中发动机指令基于预定的油门再生设定。
