Application of Model-based Development to MICU

Article of Honda R&D Technical Review Vol.25 No.2

Summary

The introduction of model-based development is being promoted to increase specification quality in the development of software for body electrical parts. This introduction requires model-based development processes and development tools. Therefore, a model-based development process was constructed that covers from analysis of requirements in the early stages of development to definition of the methods for achieving those requirements. In addition, the tools needed to efficiently promote development were developed. The constructed process was applied to trial development of a Multiplex Integrated Control Unit, and resulted in a 35% reduction in incompleteness (undefined, conflicting or ambiguous specifications) compared to control specifications created using the previous development process.
