Abstract

In powertrain development, in addition to performance design that maximizes the reduction of CO2 emissions, efficient development process with no rework and MBD (Model Based Development) are also necessary. Furthermore, fuel economy performance that assumes actual usage environment is required, EPA (U.S. Environmental Protection Agency) 5-cycle which evaluates various environments as fuel economy performance evaluation has been applied. The performance prediction considering engine temperature is essential in the EPA 5-cycle, and it is necessary to assume MBD from performance design stage to performance verification stage. This study summarizes migration from conceptual model described in previous report to detailed model and its utilization in vehicle development process.
