Problems solved by technology

[0008] However, conventional EMS mapping applied to diesel engines has the fundamental limitation that it cannot reflect RDE projects
The reason for this is that RDE cannot accurately reproduce driving conditions such as road type, outdoor temperature and pressure, traffic conditions, driving methods, etc., and the displacement should be kept at or below the specified value even under certain driving conditions

Abstract

The application relates to engine virtual test environment system and engine management system mapping method. An engine virtual test environment system may include at least one memory and at least one processor configured to perform a virtual engine test and generate a virtual engine to which a physics-based model and a data-driven model are applied to replace an engine. The at least one memory may be configured to store a physics-based model representing the actual structure of an engine by any one of simulation, phenomenological relationship expression, physical characteristic change of constituent elements, a combust model, an ECU model, and an engine model, and a data-driven model representing the actual operation of the engine by any one of a test model, a mathematical model, modeling, engine DoE techniques, mathematical and statistical techniques, a driving range.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2018-0100179 filed on August 27, 2018, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to EMS (Engine Management System) mapping of a vehicle engine, and more particularly, the present disclosure relates to a method capable of mapping virtual test results obtained in an engine virtual test environment system that can be evaluated like an actual engine virtual engine. Background technique [0004] Typically, exhaust regulations for vehicles require strict EM (emission substances) regulations for the engine. In particular, diesel engines are more stringent in terms of exhaust regulations. [0005] For this purpose, unlike gasoline engines, diesel engines apply EMS (Engine Management System) mapping. EMS mapping uses exhaust gas recirculation (EGR), boost, mul...
