Patent number: 11939931Abstract: An internal combustion engine controller comprising a memory and a processor is provided. The memory is configured to store a plurality of control maps, each control map defining a hypersurface of actuator setpoints for controlling an actuator of the internal combustion engine based on a plurality of input variables to the internal combustion engine controller. The processor comprises an engine setpoint module and a map updating module. The engine setpoint module is configured to output a control signal to each actuator based on a location on the hypersurface of the respective control map defined by the plurality of input variables. The map updating module is configured to calculate an optimised hypersurface for at least one of the control maps. The optimised hypersurface is calculated based on a real-time performance model of the internal combustion engine comprising sensor data from the internal combustion engine and the plurality of input variables.Type: GrantFiled: April 20, 2020Date of Patent: March 26, 2024Assignee: Perkins Engines Company LimitedInventors: Gavin Williams, Peter Ladlow, Max Best, Mark Scaife

Patent number: 11898513Abstract: An internal combustion engine controller for an internal combustion engine comprising a memory and a processor. The memory is configured to store a plurality of control maps, each control map defining a hypersurface of actuator setpoints for controlling an actuator of the internal combustion engine based on a plurality of input variables to the internal combustion engine controller. The processor comprises a map updating module, a parameter updating module and an engine setpoint module. The map updating module is configured to calculate an optimised hypersurface for at least one of the control maps based on a performance objective function of the internal combustion engine, sensor data from the internal combustion engine, and the plurality of input variables, wherein the performance objective function includes parameters. The parameter updating module is configured to update a parameter of the performance objective function upon determining a change in an operating condition of the internal combustion engine.Type: GrantFiled: April 20, 2020Date of Patent: February 13, 2024Assignee: Perkins Engines Company LimitedInventors: Gavin Williams, Peter Ladlow, Ridwan Kureemun, Baoyang Deng

Publication number: 20160061128Abstract: To help meet exhaust gas emissions standards, an internal combustion engine may have an exhaust gas aftertreatment device located in its exhaust gas stream. However, the exhaust gas aftertreatment device may only operate effectively above a minimum threshold temperature. In the present disclosure there is provided a method and apparatus for warming the exhaust gas aftertreatment device and a method and apparatus for controlling when exhaust gas aftertreatment device warming should be initiated and stopped.Type: ApplicationFiled: April 16, 2014Publication date: March 3, 2016Applicant: Perkins Engines Company LimitedInventors: Matthew Nicholson, Sarah Rutledge, Daniel Cunliffe, Peter Ladlow
