Abstract:
An item is a system or an array of systems used to implement a function at the vehicular level. However, owing to increasing demands for advanced functions and security features in an automobile, an item and the manner in which it is defined has become more complex. In this research, we propose using resource sharing as the basis for defining an item and its boundary. We use four simple categories for introducing an influencer that represents a shared resource and its management function. This makes the process of defining an item simple and straightforward. Further, by refining an influencer, complex interaction between systems in an item is better described. We applied this method to define an item for the sample systems.
