Title:
METHOD AND SYSTEM FOR ADAPTATION OF TRANSIENT ENGINE PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2005/028839
Kind Code:
A1
Abstract:
A method and a system for adaptation of transient engine performance capable of reducing a time for the transient test of an engine and also reducing a man-hour for preparing control software for the engine, wherein the test is performed by using the actual engine in a transient state in which the rotational speed and torque of the engine vary in time sequence. Output data as the results of the test is taken in, and the relation of the output data with the controlled values of the control factors given to the engine is taken to generate a transient engine model in which the relation of the output to the input of the engine is described. By using the prepared transient engine model, a simulation is performed to know the requirements of a target performance which can be satisfied by changing the controlled values of any of the controlled factors to provide control data meeting the requirements of the target performance. The control logic of an engine control circuit is prepared by using the control data.
