Research of Software Reliability Designing and Modeling of Electronic Control Unit of Engine

Abstract

Only the hardware system of EMS cannot guarantee the reliability of ECU because it is constrained by system cost and other factors. So it is necessary to lean upon the reliability of the software system to complement and improve the reliability of engine. In this paper, we described the structure of the software of ECU of engine and the methods and processes of the software reliability. And then, we test the reliability of the software using the white-box testing method. During the verification, to check the path of the verifying process is the same as the real path by designing four pair of different examinations. The results of the exams show that the designing method satisfying the need of verifying the software reliability.
