Matoi Iizuka, Motoyasu Mochizuki and Yasuo Hirano Toshiba Corporation Copyright © 2005 SAE International ABSTRACT AISIN AW has developed a new full hybrid transmission, the HD-10 for front wheel drive vehicles. This HD-10 has been developed based on the concept for improving fuel economy and performance without sacrificing drivability and utility. To achieve this, the transmission adopts an integrated design, which consists of two electric motors, gears including a planetary gear set, two inverters, and an electronic control unit. In addition, new software has been developed to offer smooth operation in every drive condition. INTRODUCTION Since 1986, AISIN AW has been developing drive systems for the Earth-friendl y "Environmental Vehicle" by combining our know-how as an automatic transmission manufacturer and experience with advanced motor technology. In recent years, the market has been demanding gasoline – electric hybrid vehicles to reduce carbon dioxide and other emissions, without sacrificing vehicl e performance, drivability and utility. As an answer to this requirement, AISIN AW has developed the HD-10, a new full hybrid transmission for front wheel drive (FWD) platforms, optimized for compact sport utility vehicles in 2004. This newly developed HD-10 transmission consists of two electric motors, gear sets, and an integrated inverter and controller. This integrated design eliminates high voltage cables and signal wire harnesses from the transmission's exterior and realizes high reliability and ease of installation. The stru cture of the HD-10 is widely known as power-split [1], which makes it possible for the engine to be operated along the most efficient curve, while transmitting e
