  • Patent number: 8650862
    Abstract: An agricultural machine has an internal combustion engine, a particulate filter disposed in an exhaust-system branch of the internal combustion engine, and an engine control unit designed to control the internal combustion engine in a regeneration phase in such a manner that a temperature is reached in the particulate filter that is required for the regeneration thereof, and to abort an on-going regeneration if at least one operating parameter of the machine that influences the regeneration deviates from a setpoint value. A control device of the machine is provided to predict a time period in which it is likely possible to hold the operating parameter to the setpoint value thereof, and to start regeneration when this time period begins.
