Zusammenfassung

The latest powertrain technologies such as downsizing turbo engines, continuously variable transmission (CVT) and hybrids are increasing in complexity and scale of required development effort. As a solution, Nissan has started to use a Systems Engineering focused approach the development methodology.

Because of increasing complexity, engineers from many domains are involved in systems engineering activities. Therefore, new capabilities are required for facilitating widespread understanding and discussion of the whole system. To achieve this, a unique Nissan Model Based Systems Engineering (MBSE) process was developed that uses processes, views and matrixes in a more practical and efficient way in systems engineering.

This paper describes Nissan’s MBSE approach and its application to the development of a new variable compression ratio turbo (VC-T) engine.
