Patent number: 9539997Abstract: A system and method are disclosed for controlling a power split in a hybrid powertrain having an engine and a motor. According to at least one aspect of the present disclosure, the method includes selecting a displaced fuel consumption value for the engine based on a quantity of available reclaimed energy in a battery, where the displaced fuel consumption value favors using the quantity of available reclaimed energy at relatively high load conditions, operating the engine at a condition based on the displaced fuel consumption value to generate engine power to meet at least a portion of a power demand, and operating the motor to generate motor power sufficient to supply a remaining power demand not met by the engine power. The system includes a controller configured to perform the operations of the method.Type: GrantFiled: July 29, 2014Date of Patent: January 10, 2017Assignee: Cummins Inc.Inventors: Zhen Sun, Morgan MacKenzie Andreae, Martin T.

Patent number: 9389145Abstract: Diesel electric hybrid powertrains and methods of operating and testing such powertrains are disclosed. Certain exemplary embodiments comprise test and certification methods in which a controller operates a diesel engine alone, an integrated motor/generator alone, or both the diesel engine and the motor/generator to provide brake torque at a common output shaft according to predetermined duty cycle criteria. Emissions are measured based upon criteria accounting for the effects of regenerative braking, engine shut off, and other operational modes unique to hybrid powertrains. Further exemplary embodiments comprise hybrid powertrain systems and methods of operating the same meeting performance and emissions requirements including respective limits on NOx, hydrocarbon, particulate matter, CO, and CO2 without reliance conventional emissions reduction devices or techniques.Type: GrantFiled: December 20, 2013Date of Patent: July 12, 2016Assignee: Cummins Inc.Inventor: Morgan MacKenzie Andreae

Patent number: 9243541Abstract: A method for controlling aftertreatment regeneration for a system having a hybrid powertrain is described. The method includes determining that an engine aftertreatment regeneration is indicated when a regeneration request index exceeds a first threshold. The method includes determining an acceptable battery usage amount based on a current battery state of charge (SOC) and a minimum battery SOC. The method further includes determining a battery usage amount for an engine aftertreatment regeneration operation. The method includes initiating an engine aftertreatment regeneration when the battery usage amount is less than or equal to the acceptable battery usage amount.Type: GrantFiled: August 21, 2013Date of Patent: January 26, 2016Assignee: Cummins Inc.Inventors: Vivek Anand Sujan, J. Stephen Wills, Morgan MacKenzie Andreae, Martin T. Books

Patent number: 9043060Abstract: A system includes a hybrid drive system having an internal combustion engine and a non-combustion motive power source. The system includes an energy storage system and a controller. The controller is structured to functionally execute operations to improve an efficiency of they hybrid drive system. The controller interprets duty cycle data, a boundary condition, and an optimization criterion. The controller further elects a load response operating condition in response to the duty cycle data, the boundary condition, and the optimization criterion. The controller adjusts the operation of the engine and/or the motive power source in response to the elected load response operating condition.Type: GrantFiled: January 3, 2012Date of Patent: May 26, 2015Assignee: Cummins Inc.Inventors: Vivek Anand Sujan, Morgan MacKenzie Andreae, Martin T. Books, Xi Wei, Terrence Shaw
