There is a need in the Motor Industry to reduce product development cycle time and drive down development costs by reducing the amount of testing required and reducing the reliance on expensive prototype vehicles. In order to achieve this goal new innovative processes must be developed with increased use of CAE and desktop calibration. Ford Motor Company with the Mathworks has developed a suite of tools to enable reduced testing, increased proportion of desktop calibration and a significant increase in test data reusability within the EOBD (European On-Board Diagnosis) calibration process. The new process makes use of Simulink strategy models with a user friendly front end GUI to enable easy desktop calibration and validation, a new data editor tool to enable fast batch processing of recorded calibration data, the use of the MBC toolset to develop accurate surface models of key EOBD control system characteristics and CAGE to populate calibration parameters from the MBC models. very flexible and can be linked to any Simulink model that is configured correctly. The data post processing tool can be used to evaluate data collected from any calibration process and being linked to the MBC toolset can perform a wide range of data manipulation and interrogation. Simulink simulation tools have also been used to develop and validate calibrations for exhaust gas temperature models as well as FMEM calibrations for coolant temperature, MAP and MAP sensors. This paper gives an overview of the process and tools giving some practical examples of their application.
