Development of a New Hybrid Transmission for FWD Sports Utility Vehicles

A new hybrid transmission (P310) has been developed for FWD 3-liter engine class sports utility vehicles. The development of this transmission has been aimed at improving power performance and fuel economy, achieving the world's top-level weight reduction and compact size, while maintaining high torque capacity. In order to achieve these goals, the gear train and motor have been newly designed, and advanced technology has been applied. Moreover, this hybrid transmission achieves seamless acceleration and quiet performance. This paper describes the major features and performance of this transmission in detail.
