Patent ID: 11719181

Abstract:
An internal combustion engine controller for controlling an internal combustion engine is provided. The internal combustion engine controller comprises 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 an engine setpoint module and a map updating module. The map updating module is configured to optimise one or more of the hypersurfaces of the control maps at the location defined by the plurality of input variables. The map updating module comprises an optimiser module configured to search for an optimised group of actuator setpoints wherein the map updating module updates the one or more hypersurfaces at the location defined by the plurality of input variables based on the optimised group of actuator setpoints. A method of controlling an internal combustion engine is also provided.
