The Hardwear-In-the-Loop Simulator (HILS) method has been discussed as a national and global technical regulation. However, the present Hybrid Electric Vehicle (HEV) model software used in the HILS method is copyrighted and cannot be disclosed. Therefore, we previously developed a rigid-body drivetrain model corresponding to a parallel HEV equipped with an automated manual transmission or manual transmission. In this study, we developed a rigid-body drivetrain model corresponding to a parallel HEV equipped with a fluid coupling/lock-up clutch and confirmed that the developed drivetrain model had sufficient accuracy for use in certification tests.

Ambient aerosols were measured simultaneously using three aerosol mass spectrometers in the Kanto area during the summer of 2011. Organic aerosol (OA) was detected as the major component in this sampling campaign. The organic aerosol mass spectra was divided into two OA components, oxygenated organic aerosol (OOA) and hydrocarbon-like organic aerosol (HOA), using positive matrix factorization (PMF). OOA was ubiquitous in various atmospheric environments, on average accounting for 44% of the total OA in Saitama (urban), 49% in Kazo (rural), and 55% in Maebashi (rural).
