ENGINE STATE PARAMETER ESTIMATION COMPRISING THE MEASUREMENT OF THE INTERNAL PRESSURE OF A CYLINDER

摘要

The invention relates to a system for estimating the state parameters of an internal combustion engine (2), including: at least one cylinder (3), a moving piston (4) driven by means of a crankshaft (6), means (20, 21) for measuring temporal variations in the angle of the crankshaft and the internal pressure of the cylinder, at least one physical model (231) for calculating a plurality of intermediate temporal variables from said crankshaft angle and cylinder internal pressure measurements and from a measurement of at least one state parameter of the engine, a means (24) for creating tables of discretised temporal variables from the intermediate temporal variables, and a learning model (28) for estimating at least one state parameter of the engine (2) from said tables of discretised temporal variables.
