EnvSim: A Novel Framework for Verifying Engine Management System Strategies under Simulink Environment

Abstract

Engine Management System (EMS) is one of the most important and complex control systems in motor vehicles. The complexity of EMS strategies has recently increased even more in order to satisfy the more strict emissions legislations and safety standards. In order to cope with this challenge, Model Based Design is adopted. In this paper a"EnvSima" is proposed and developed as a framework for simulating and verifying Engine Management Systems strategies using Model Based Design under Simulink environment. EnvSim addresses several challenges of simulating and verifying EMS strategies, namely, creating engine specific ECU events, verifying the control strategy using realistic test data and satisfying the recommendations of the safety standard ISO26262. The application of EnvSim on a case study is presented and results are discussed, showing the effectiveness of the proposed framework.
