Publication number: 20200116100Abstract: The present disclosure relates to systems and methods for managing engine output. A method includes receiving at least one of a torque input and an acceleration input; generating a torque request for an engine; receiving the torque request; and determining an amount of the torque request that can be provided by a fast response actuator including a spark timing actuator based on a governed torque fraction value based on existing operating conditions of the spark timing actuator and a torque fraction value indicative of a total torque request value and an anticipated future torque demand value. The method includes managing the spark timing actuator to produce the amount of torque; determining a remaining amount of the torque request that cannot be provided the fast response actuator based on an existing operating condition of the engine; and commanding a slow response actuator to provide the remaining amount of the torque request.Type: ApplicationFiled: December 16, 2019Publication date: April 16, 2020Applicant: Cummins IP, Inc.Inventors: David J. Stroh, Zachary Schwab, Govindarajan Kothandaraman, Robert J. Thomas, Richard S. Fox, Craig M. Calmer, Rohit Zope

Patent number: 10508614Abstract: The present disclosure relates to a system for managing engine output that includes a machine manager module and a combustion module. In one embodiment, the combustion module includes a slow response pathway and a fast response pathway. The slow response pathway includes managing air and fuel actuators and the fast response pathway includes managing spark timing. According to one embodiment, managing spark timing comprises bringing a spark actuator to the middle of a spark timing range for bi-directional control and involves sacrificing engine efficiency for engine responsiveness. Further, the fast response pathway may be selectively enabled based upon an optimization index.Type: GrantFiled: June 5, 2013Date of Patent: December 17, 2019Assignee: Cummins IP, Inc.Inventors: David J. Stroh, Zachary Schwab, Govindarajan Kothandaraman, Robert J. Thomas, Richard S. Fox, Craig M. Calmer, Rohit Zope

Patent number: 8639403Abstract: A method includes manufacturing a first assembly having an application requirements module that interprets a contemporaneous performance specification, and an energy partitioning module that provides an electric motor torque target, a battery power flux target, and an internal combustion engine torque target. The method further includes manufacturing a second assembly having an engine control module that controls an internal combustion engine in response to the internal combustion engine torque target. The method includes integrating the first assembly and the second assembly with a third assembly to form a completed hybrid power train, where the third assembly includes a datalink that receives the internal combustion engine torque target from the first assembly and provides the internal combustion engine torque target to the second assembly.Type: GrantFiled: December 29, 2010Date of Patent: January 28, 2014Assignee: Cummins Inc.Inventors: Martin T.
