Power Train for a New Compact Sporty Hybrid Vehicle 2010-01-1095

This paper presents a power train developed for a 2011-model compact sporty hybrid vehicle. The power train, developed based on existing mass-produced car components such as an engine, transmission, and Integrated Motor Assist (IMA) system, takes advantage of the IMA system to strike a good balance of driving performance, fuel economy, and low exhaust gas emissions. The conventional concept behind a hybrid design was to use motor output to compensate for a power reduction caused by smaller engine displacement. For the development of this power train, a new approach was taken to utilize the motor output to create a better driving feel. Making full use of a good motor response and directness, the power train realized this sporty driving feel, unlike anything offered by conventional cars.
