Honda Develops New Lightweight and Compact Hybrid System Named "SPORT HYBRID
Intelligent Dual Clutch Drive" 
Three Different Honda SPORT HYBRID Systems Accommodate Different Vehicle
Characteristics 
Tokyo, Nov 13, 2012 - (JCN Newswire) - Honda Motor Co., Ltd. developed the
SPORT HYBRID Intelligent Dual Clutch Drive system, a lightweight and compact
one-motor hybrid system optimized for small-sized vehicles. This new hybrid
system will be the latest addition to the Earth Dreams Technology series of new
generation powertrain technology that realizes both excellent driving
performance and fuel economy at a high level. 
Together with the SPORT HYBRID Intelligent Multi Mode Drive, the world's
most efficient(1) two-motor hybrid system optimized for mid-sized vehicles, and
the SPORT HYBRID SH-AWD(R) (SPORT HYBRID Super Handling - All Wheel Drive), the
three-motor hybrid system optimized for large-sized vehicles enabling
independent control of torque distribution to both right and left rear wheels,
the newly developed SPORT HYBRID Intelligent Dual Clutch Drive will constitute
the lineup of three different Honda SPORT HYBRID systems that accommodate
different vehicle characteristics. Honda will continue expanding the
application of these hybrid systems based on vehicle characteristics. 
The lineup of SPORT HYBRID systems 
1. One-motor SPORT HYBRID Intelligent Dual Clutch Drive: 
In addition to top level fuel economy in its class(2), the fun of driving is
realized with acceleration g-force more powerful than that of existing models
as well as a rhythmic and linear acceleration feeling. This drive unit combines
a newly developed inline 4-cylinder 1.5L Atkinson cycle engine with a 7-speed
DCT(3) system with a built-in high-output motor and a lithium-ion battery to
improve efficiency by more than 30% compared to a conventional one-motor hybrid
system. 
Outline of the system 
- The combination of the one-motor hybrid system and the engine realizes
sporty driving during acceleration and high-speed cruising by using the
clutches to engage the engine.
- Highly efficient electric vehicle (EV) driving is realized during startup
and low- to medium-speed cruising by using the clutches to disengage the
engine.
- This system contributes to the improvement of fuel economy by increasing
energy regeneration using the clutches to disengage the engine during
deceleration. 
2. Two-motor SPORT HYBRID Intelligent Multi Mode Drive / Plug-in: 
Through the adoption of high-efficiency / high-output motors, both brisk
acceleration with an EV-like driving feel and high fuel economy are realized at
the same time. This hybrid system realizes the world's highest
efficiency*1 by combining a newly-developed engine dedicated for hybrid
vehicles and an electric CVT coupled with two built-in motors and a lock-up
clutch, along with a lithium-ion battery, and by optimally switching the
driving mode among three different modes depending on the driving situation.
This hybrid system, which is also suitable as a plug-in hybrid system, will be
installed to the North American version of the Accord, scheduled to be
introduced to the market in January 2013. 
Outline of the system 
The system switches the operation among the following three driving modes
depending on driving conditions and the battery charge level: 
- "EV Drive" for driving by the electric motor using electricity
from the battery and regeneration during deceleration
- "Engine Drive" for medium- to high-speed cruising with the engine
and axle directly connected by a lock-up clutch and engine power is
mechanically transferred to the wheels
- "Hybrid Drive" for urban driving and powerful acceleration using
the motor with electricity generated by the engine 
3. Three-motor SPORT HYBRID SH-AWD(R) (SPORT HYBRID Super Handling - All Wheel
Drive): 
The combination of a V6 engine and this high-output three-motor system
realizes acceleration performance equivalent to that of a V8 engine with fuel
economy better than that of an inline 4-cylinder engine. A new V6 3.5L
direct-injection engine is installed in the front of the vehicle and combined
with a newly-developed 7-speed DCT system with a built-in motor. This unique
Honda technology uses two motors installed in the rear to control torque
distribution to the right and left rear wheels. 
Outline of the system 
- Using independent motors for the right and left rear wheels, positive torque
is applied to the outside wheel and negative torque is applied to the inside
wheel, making independent control of torque distribution to the rear wheels
possible without relying on engine output.
- Depending on the radius of the curve, the energy generated by the inside
wheel is recovered electrically and applied to the outside wheel to
self-generate torque necessary for the vehicle to make the turn.
