A Study of Evaluating the Real-time Property for Engine Control Software 2001-01-0058
Recently, the role of ECU(Electronic Control Unit) on vehicles has been becoming more important year by year in order to meet the requirements for safety and the environmental matters. Particularly, the ECU of Engine Management Systems has been becoming indispensable in order to realize high performance, low fuel consumption and low exhaust emission. Therefore, the size of software has also been increasing, and been becoming more complex and complicated.
As the ECU software size becomes large and complex, the verification and validation of the software by using the current development method has been becoming more difficult. Especially it has been becoming more difficult to validate the Real-time property of the software. The Real-time property means whether the execution of the software is in time for the deadline which is decided on the software design.
This paper describes the methods that make it possible to verify the Real-time situations of the Engine Control Software by applying the informational theory called RMA(Rate Monotonic Analysis) and experimental analysis in the early stage of the software design.
