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.

In recent years, researchers have begun to focus on wearable computer
and sensor interfaces. One major benefit provided by wearable
intelligent devices is that they are in close proximity to the users
so that human data such as motion and physiological information can be
obtained and analyzed anywhere at anytime. One area for wearable
devices has, however, remained relatively unexplored-namely, the
design and implementation of sensor and computer-equipped intelligent
shoes. Therefore, we propose the development of just such a system.
The on-going miniaturization revolution in electronics, sensor and
battery technologies, driven largely by the cell phone and hand-held
device markets, has made possible an intelligent-shoe implementation.
Along with these hardware advances, progress in human data modeling
and machine learning algorithms have also made possible the analysis
and interpretation of complex, multi-channel sensor data. Our
intelligent shoe system will leverage progress in these areas. The
intelligent shoe system will consist of a microcontroller, sensor
suite for physiological, motion and force readings, and a wireless
transmitter to be attached or implanted in normal shoes as a compact
and light-weight attachment. Once prototyped, we will collect
experimental sensor data for a variety of activities and a cross
section of the population. These data will then be analyzed to meet
three primary goals: (1) real-time health and gait monitoring; (2)
real-time motion (activity) identification; and (3) real-time user
localization. We will propose various intelligent learning algorithms,
such as hidden Markov models and support vector machines, to achieve
the modeling of human motion and physiological data. The proposed
research opens up tremendous new human-computer interface
possibilities, resulting in rich academic research contents and
potential product lines in consumer electronics and multimedia
industries.
