OHEV


Today we face two major crises: the problem of energy and emission.
The hybrid electric vehicle (HEV) concept is the best approach to
solve them, as it saves fuel energy by optimizing the vehicle power
and at the same time reduces pollution by controlling the emission.
Serial HEVs also simplify the mechanical transmission and makes it
possible for 'drive by wire'.

The proposal is to develop a serial hybrid electric vehicle platform
that demonstrates the key technologies for commercial use. It will
involve the following three major areas:

(1) Intelligent energy management and control technology based on
serial hybrid design for optimization of engine. We will develop an
intelligent HEV energy management and control system that harmonizes
the following key components:

Battery as power source

Engine/Electric generator as auxiliary power unit

Electric motor for wheels

Control area network for communication between components in the
vehicle

HEV control system for the coordination and control between the
components
Power management and control system that optimizes vehicle performance
based on output power, fuel consumption and emission.

(2) 4-independent-wheel-drive that can improve the efficiency through
electronic differential which substitute for mechanic differential;
wheel control system that can enable 4-wheel-steering with independent
suspension for omni-directional motion:

4-wheel drive
4-wheel steering
Antiskid control in multiple directions
Intelligent road condition estimation
(3) Intelligent electronic system for coordination of forward
collision warning and avoidance system stop&go and cruise system and
intelligent information platform:

An automatic navigational system for parking based on restricted
maneuvers that advantage of 4WS mechanism
Intelligent architectural-electronic-based information platform that
supports
Intelligent car safety system based on modeling of human dynamic
driving behaviors
The goal is to save 20% fuel consumption, and substantially reduce
pollution emission and improve safety. It is believable that the IOHEV
R&D will impact significantly impact car manufacturing, energy as well
as environment protection.
