ENGINE CONTROL METHOD FOR A VEHICLE TO INCREASE COMPUTATIONAL EFFICIENCY

摘要

A method of engine control for a vehicle, comprising:generating a first torque request for a spark-ignition engine (102) based on driver input;translating the first torque request into a second torque request;determining a current set of setpoints based on the second torque request, a model of the engine, a tableau matrix and a base solution matrix using model predictive control;characterized in that the determining includes:initializing the base solution matrix to a given matrix that is dual permissible;optionally iteratively updating the base solution matrix and columns of the tableau matrix;determining changes for the target values, respectively based on base solution matrix entries resulting from the selective iterative updating; anddetermining the current set of target values by summing each change with a last set of target values; andcontrolling an engine actuator based on a first of the current set of setpoints.
