Target-identical rapid control prototyping platform for model-based engine control

Abstract

Rapid control prototyping (RCP) is one of the most important technologies for speeding up the development process of the electronic control unit (ECU) used in the automotive control system. However, one big drawback of the conventional RCP platform is the transfer from RCP to target ECU implementation. In this study, a new RCP platform is proposed that provides a consistent environment for both the RCP development stage and the target ECU implementation stage. In order to make the rapid prototyping controller as similar to a production ECU as possible, the prototyping system follows the strictly layered architecture of the production ECU and separates the automatically generated code of software from the hand code. Finally, the feasibility of the developed target-identical RCP platform is evaluated through an air-to-fuel ratio (AFR) control application.
