Hybrid and Electric Vehicle Technologies Symposium

Shinichi Abe

Chief Professional Engineer, Electric Powertrain System Development, Toyota Motor Corporation

The combined contributions of Takehisa Yaegashi, Shoichi Sasaki and Shinichi Abe enabled the development and commercialization of hybrid electric vehicles (HEVs) that have revolutionized the automotive industry. They created the “Toyota Hybrid System” (THS), resulting in the 1997 Toyota Prius and impacting future versions of HEV technology. The world’s first mass-produced HEV, the Prius obtained revolutionary fuel efficiency using the THS. Dr. Yaegashi directed the establishment of the integrated vehicle energy management system. He then improved the first-generation technology to create THS II, featured in the 2004 Prius, which significantly improved fuel efficiency, performance and cost reduction. Professor Sasaki developed a unified control algorithm that achieved optimal fuel efficiency and control of the engine, motor and battery. His algorithm has been applied to all Toyota hybrid vehicles. Mr. Abe was responsible for ensuring low emissions and drivability of
