Functional Design of a Motor Integrated CVT for a Parallel HEV 1999-01-0753

We succeeded in developing a parallel hybrid electric vehicle (HEV) with a fuel efficiency in the 10-15 mode more than double that of existing vehicles of the same class of driving performance. A prominent feature of this HEV system is the belt-drive continuously variable transmission (CVT) with built-in traction motor and powder clutch. Adopting a more efficient configuration proved effective in minimizing cost increases and loss of space utility and offered the same reliability provided by existing vehicles.
This paper discusses the functional design aspects of the parallel HEV system, which holds great promise for viable mass production.
