Bosch and Getrag to Work Together on Hybrid Systems
5 June 2006

Bosch and Getrag have agreed to work together on hybrid systems. The new partnership covers the development and marketing of parallel hybrid systems in conjunction with dual-clutch transmissions and electrical final-drive units. Getrag is a specialist in dual-clutch transmissions.
Key aspects of the collaboration include the integration of mechanical and electrical components and the development of appropriate software. The collaboration also involves the development of final-drive units with directly integrated electric motors.
In a parallel hybrid, the electric drive that provides drive assistance and regenerative braking is fitted directly into the power flow of the drivetrain. The dual-clutch transmission enables easy and energy-efficient automatic shifting.
Getrag offers a broad product portfolio covering the entire drivetrain and especially dual-clutch transmission technology. Bosch brings to the partnership its know-how in electrical machinery and the necessary power electronics.
Together we can offer automobile manufacturers a highly integrated and compact hybrid system that will enable low fuel consumption and excellent vehicle dynamics.—Dr. Bernd Bohr, member of the Bosch Board of Management
Bosch announced in 2005 that it was developing a full family of hybrid drive solutions, and plans initial production of the first member—a micro-hybrid electronic start/stop system—this year. (Earlier post.)
Getrag had shown several hybrid system prototypes at IAA 2005 in Frankfurt, including a single-motor parallel mild-hybrid system and a two-motor powersplit full-hybrid, both based on the same Flexible Modular Hybrid platform.
