This paper presents the different type of simulation tools that are used at Renault during the engine calibration process from the first model-based assessment at the beginning of the project, to the final calibration on vehicle. The most profitable areas for the implementation of computer-aided calibration (CAC) methods are detailed for current engine technologies and performance requirements (emissions, drivability, etc). As a concrete example of CAC methods applied to Diesel engine, this paper will focus on model-based calibration of Diesel particulate filter regeneration. The prototype tool previously presented in 2008, has been successfully implemented within the industrial powertrain calibration process. It brings a significant reduction of the amount of vehicle tests in comparison to the previous practices. Besides, it provides to people in charge of calibration a direct link to the physical phenomena of soot combustion within the particulate filter. Finally, the next steps for the implementation of CAC methods within the calibration process will be discussed taking into account the new coming engine technologies and future demands regarding emissions and drivability.
