Development of commercial hybrid vehicle automatic transmission system

Abstract

As demands for a reduction in CO2 emissions and higher vehicle fuel efficiency are escalating on a global scale, needs not only for passenger hybrid vehicles but also for commercial hybrid vehicles are arising accordingly. In 2008, we developed Automatic Transmission (AT) system with Hino Motors which was compatible with hybrid vehicle [1], therefore, this time, we developed a new hybrid front module containing a front clutch mechanism, which is intended to further optimize the hybrid AT system and capable of disconnecting the hybrid vehicle motor and the engine, to achieve better compatibility with the AT system. © 2013 Springer-Verlag.
