Delphi Teams With State of Indiana To Advance Electric
Brake-By-Wire Development
TROY, Mich., March 13 /PRNewswire/ -- Delphi Automotive
Systems  announced today it is part of a team
headed by the state of Indiana that has been selected by the
U.S. Department of Energy to participate in a cooperative
agreement to research, develop and demonstrate switched
reluctance machine (SRM) technology.  The technology will be
applied to electric brake-by-wire systems for hybrid
electric, fuel cell and battery electric powered advanced
high efficiency vehicles.
[...]
These high efficiency vehicles require accessory systems,
such as brakes, to be redesigned to function independent of
engine operation.  The focus of this project is to design
and build a brake-by-wire electromechanical actuator that
outperforms today's systems and is independent of vacuum
produced by the engine.  The actuator is based on a SRM with
an integrated power converter and machine controller.  Once
developed, this system will ultimately replace the
vacuum-assisted hydraulic actuator found in today's
vehicles, enabling the required engine-independence.

"Delphi is pleased to be selected to participate in this
important agreement to develop advanced transportation
technologies," said Jean Botti, chief technologist,
Innovation Center, Delphi Dynamics & Propulsion Sector.
"While SRMs have been available in a number of applications
for several years, the integration of switched reluctance
machine technology and electronics, in a package that is
compact, robust and affordable, will offer a significant
advancement toward a brake-by-wire system that can be
manufactured and marketed."

The award, in excess of $850,000, supports the Bush
Administration's National Energy Plan and the recently
announced FreedomCAR program to develop the technical
ability to meet U.S. energy challenges.  The cost-share
program includes a contribution from the state of Indiana;
program administration support from Electricore, which is an
advanced technology consortium; brake- by-wire, motor design
and control expertise from Delphi Energy & Chassis Systems;
and simulation, analysis and algorithm development expertise
from Purdue University.

In addition to enabling the braking system to function with
power assist without the engine running, brake-by-wire
offers many improvements when compared to conventional
braking systems.  Brake-by-wire can provide improved brake
force control and integrates with other chassis systems,
such as steering and suspension, resulting in a higher level
of vehicle stability and performance.  Improvement can also
be achieved in fuel efficiency by reducing braking system
weight and eliminating brake drag, which also increases
brake pad life.

"SRMs offer technical advantages over other machine
technologies when applied to the brake-by-wire application,
including a much smaller package and reduced mass at the
wheel, compared to a brush-type motor," said R. Scott
Bailey, director of engineering, Delphi Energy & Chassis
Systems.  "These attributes have a significant impact on the
performance of the vehicle's braking systems and suspension,
as well as improving energy efficiency."
