Abstract: The present invention refers to a method for generating a control command to at least one actuator of an electrohydraulic machine, comprising a step of receiving and monitoring an input signal provided by a user interface, a step of determining if the monitored input signal is related to a user-induced input or a non-user-induced input, and a step of generating the control command upon processing the input signal in dependence on whether the input signal is a user-induced input or a non-user-induced input.

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.
