Abstract

A regeneration disable control system (22) of a vehicle having a power take off device (10) that is run off a motor (12) which is powered by at least one battery (14), and an engine (16) for recharging the at least one battery and for regenerating a diesel particulate filter (20), includes a hybrid controller (18). The hybrid controller (18) sends a signal to an engine controller (21) to indicate whether hybrid-PTO mode is enabled. If the hybrid-PTO mode is enabled, the engine controller (21) determines whether regeneration of the diesel particulate filter (20) is required. If regeneration is required, the engine controller (21) sends a signal to a regeneration inhibitor (30) to disable the engine (16) from initiating a regeneration event.
