Research on Establishing the Model Framework Method for Vehicle Electronic Information System Based on ICD

Abstract

In the vehicle electronic information system, there is a growing number of data interfaces between devices, and data types are more and more. In the process of device modeling, modifying an interface data involves not only modifying the model associated with it, but also the modification of many communication interfaces. The modification process is complex, resulting in an extension of the modeling cycle. In order to solve this problem, a method was presented in this paper to generate Simulink interface model framework based on ICD. If the ICD needs to be modified, just update the ICD and regenerate interface model framework to complete the modification of all relevant interface models. This method solves the problem of the interface mismatch caused by ICD modification, shortening the modeling period. It is proved that this method is feasible and effective, and can greatly accelerate the establishment of the model.
