Case-based adaptation for automotive engine electronic control unit calibration

Neuro-Hybrid Models for Automotive System Identification

In automotive systems almost all steps concerning the calibration of several control systems, e.g., low idle governor or boost pressure governor, are made with the vehicle because the timeto-production and cost requirements on the projects do not allow for the vehicle analysis necessary to build reliable models. Here is presented a procedure using parametric and NN (neural network) models that ...

Concurrent WAVE/Matlab Simulink Simulation Applied to HSDI Diesel ECU Calibration

This paper describes an application of an engine cycle simulation code (WAVE) in co-simulation with a control and dynamics modelling package (Matlab Simulink) to provide total vehicle system modelling capability. The models presented form the basis of an Analytical Calibration CAE toolset allowing the definition of many electronic control unit (ECU) calibration parameters in the CAE environment...

Latest Trends In Automotive Electronic Systems - Highway Meets Off-Highway?

The rapid development of electronic systems in automotive vehicles has been driven for decades by constantly growing requirements of legislation for environmental protection, as well as rising demands of the end-user to improve fuel economy, safety, driving comfort and driving excitement. The manufacturers of mobile work machines also see themselves increasingly confronted with these requiremen...

Complementing an Interval Based Diagnosis Method With Sign Reasoning in the Automotive Domain

In the automotive field, the use of an ECU (Electronic Control Unit) to control several functions (such as engine injection or ABS) increases. To diagnose such systems, diagnosis trees are built. These trees allow the garage mechanics to find the faulty component(s) by performing a set of tests (measurements) which has the lowest global cost as possible. Two methods, interval based and sign con...
