Abstract
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. The map updating module further is configured to update the hypersurface of the control map based on the optimised hypersurface. A method of controlling an internal combustion engine is also provided.
