Model-Based Development Technologies to Support Increasingly Complex Power Train Systems

Article of Honda R&D Technical Review Vol.26 No.2


In order to support power train systems as they become increasingly complex, as well as to raise the efficiency and quality of development, it is useful to (1) clearly define requirements and verification items, (2) structure requirements and clearly define interfaces, and (3) assure the traceability of requirements.
The present research project used Systems Modeling Language, which is a semi-formal notation. By formulating the project’s own original guidelines, the above three items were achieved.
Requirement models written in Systems Modeling Language are also published to suppliers as requirement specifications for the platform area of the power train electronic control unit. Therefore the tasks involved in efficiently and accurately verifying not only the validity of the requirements, but also whether or not problems exist in how they are written as requirement specifications, were defined and applied in parts to the development of 2015 model year mass-production models.
