Actor-Oriented Methodology for Automotive Engine Control System Design
Guojun Huang, Wenqing Huang, Youtong Zhang · 2010
Engine control systems, consisted of ECU hardware, software, sensors, and actuators, are the most significant part of automotive control, and can be considered as mixed-signal systems which interact with engine through sensors and actuators. In this article, we present a component-based modeling and simulation framework for automotive system design. This component framework is compatible with AUTOSAR basic software modules, based on actor meta-model, using a hierarchical approach to manage heterogeneity in modeling automotive control systems. Semantically different frameworks are composed hierarchically to manage heterogeneous models and achieve actor and framework reuse. A framework is also an environment that actors reside in and is also as a platform for engine control system design. The methodology was implemented in the Ptolemy II software environment. Examples were given to show the applications of this framework in a common-rail testbed control system we designed for Beijing Public Transport Service Co.
