A New Approach for the Validation of Engine Management Strategies Specifications Through Simulation Algorithms

The increased complexity of the electronic control systems requires exhaustive debugging algorithms. In this paper a validation methodology for the engine management strategies specifications is described. It is based on mathematical simulation and testing using finite state machine (FSM) integrated in an engine model. Considering the strategies management built with states and transitions diagrams, a simulation environment has been developed where a two-ECU (Electronic Control Unit) system is clocked with parallelism. Advantage consists of debug time reduction in the validation and software testing. This paper presents an efficient and exhaustive method to create specifications in terms of FSM and tasks scheduling.
