, Closely networked systems and
components developed by Continental Automotive Systems help advance
Volkswagen's new Passat to the front of the class . It is as convenient as an
automatic but offers all the driving pleasure and fuel economy of a manual
gearbox.

CAN Gateway: keeping the data highway flowing
In the new Passat, the switches , sensors and motors for electronic
functions are networked.
(NYSE: ARM) and Meritor WABCO Vehicle Control Systems announced today their
new Premium Hydraulic Braking System for medium-duty truck and bus
applications. Drivers will appreciate pedal "feel"
similar to that of a passenger car , while fleets and owner-operators will
benefit from longer lining life, fewer aftermarket parts and single-source
shopping.
In addition to ATC, the system can accommodate the stability enhancement
capability which has never before been available to the medium-duty market.

Initiating emergency braking in the Passat takes very little effort. The
brake booster developed and supplied by Continental Teves has a two-stage
design. For additional information, visit our

The premium package is available immediately to North American original
equipment manufacturers' vehicles."
In addition to the design advantages, the brake caliper sizes can be used
inter-changeably by utilizing the same torque plates and rotors, reducing
aftermarket parts requirements.

They give a high-quality look to interior areas that
drivers and passengers touch and see every day, and retain their finish even
after many years of use. Proportional
to that signal, the accumulators provide pressure to the brake calipers. Customers include the world 's leading commercial
truck, trailer, bus and passenger car manufacturers.

This control unit recognizes which
signals are to be transmitted to each destination within the vehicle and can
also identify their priority. High-performance V-belts and V-ribbed
belts drive ancillaries, and ContiTech bearings and dampers minimize
unpleasant vibrations.
Combined, these two brake technologies offer unparalleled stopping and
performance capabilities."
"Our hydraulic disc brake has been proven in hundreds of thousands of
miles since it entered the market in 1997," said Pedro Ferro, vice president
and general manager of Worldwide Braking Systems and Commercial Vehicle
Emissions, ArvinMeritor. "Motor carriers appreciate its easy-
to-maintain design, fewer service parts, lower maintenance costs, added
durability, and superior stopping performance.

The power losses associated with a conventional automatic are
also a thing of the past.
The driver just accelerates and brakes -- everything else is handled by a
Continental Temic mechatronic control unit with smart electronics and sensors
integrated into the transmission housing.

Durable quality: rubber, plastic and hoses
Making quality visible -- ContiTech company Benecke-Kaliko has put this
principle into practice in the new Passat by developing very high-quality trim
components.
"The new HPB system offers significant advancements .
"The enhanced stopping performance delivered by the new HPB is
accomplished through faster reaction time when compared to other available
hydraulic braking systems," said Alan Korn, chief engineer, Meritor WABCO
Vehicle Control Systems.
The new HPB provides further advantages via its parking brake Auto-Apply
function. When a vehicle's automatic transmission is placed in Park position,
the park brake will automatically apply.
The enhanced robustness of this brake is complemented by simplified
maintenance.

This data is essential for the
ABS, the traction control system (ASR) and the electronic stability control
system (ESC)., ArvinMeritor, Inc. This results in
improved stopping performance and allows the vehicle to adjust for consistent
brake feel independent of the load. Reduced affects of external influences result
in longer lining life and reduced vehicle maintenance costs. Founded in the US 136
years ago as Westinghouse Air Brake Company, WABCO was acquired by American
Standard in 1968., ArvinMeritor employs approximately 31,000 people
at more than 120 manufacturing facilities in 25 countries.

These components are designed for long service lives and are extremely durable
even with little care. The
system provides three important functions:
* does not require the use of an external source to provide power assist
to achieve a low pedal effort as required in a conventional hydraulic braking
system;
* brake control functions, including ABS, automatic traction control
(ATC), and electronic brake force distribution (EBD); and
* optional auto-apply electronic parking brake control.

"Since its introduction several years ago, the Quadraulic disc brake has
gained wide acceptance as a standard brake, on various vocational vehicles,
providing premium results," said Prakash Jain , business unit director, Wheel
End and Hydraulic Brakes, ArvinMeritor. Reducing inventory requirements even further,
the two caliper sizes available with this brake (4 x 64 mm and 4 x 70 mm), use
common brake pads (no unique inner/outer or directional pads), torque plates,
hubs/rotors, and fasteners to attach the caliper to torque plate and rotor to
hub.

HPB System
The HPB is a braking and vehicle control system for vehicles in classes
four through seven, and buses that are equipped with hydraulic brakes. When the vehicle's ignition is
turned on, internal pumps are activated and fill both accumulators with
pressurized hydraulic brake fluid. "This improved reaction time is a direct result of
the stored energy in the accumulators, which are features distinct to this
system . When lining changes are required, only the lining retention bolt
needs to be removed and the new linings can be dropped into the caliper.

Networked Systems = Safety and Comfort; New Passat Relies on Continental Brake and Transmission Technologies

For example, if the commands "close sliding
roof " and "switch on brake light" meet on the data highway, the second signal
is given absolute priority because it is safety-relevant. Recognizing the
priorities at once, the CAN gateway makes sure that the signal from the brake
light switch on the brake booster reaches the brake lights as fast as
possible . Continental Teves
supplies both the wheel speed information software and the sensors.
When required , hydraulic pressure is supplied and released to the appropriate
foundation brake to achieve the desired functional effect. The Auto-Apply will also function
when the ignition key is switched off.
"HPB represents a breakthrough in braking control for hydraulically-braked
vehicles," commented Korn. The fixed caliper eliminates a
main concern often associated with rail slider or pin slider designs --
external environment factors.

It has the advantage
of better protection against damage and no mechanical wear compared to a

provide additional boost. "Together, the HPB and Quadraulic disc brakes
achieve unrivaled stopping performance, providing motor carriers' added safety
to vehicle operators. For ABS and ATC activation, pressure at the wheel is individually
modulated by ABS and ATC solenoid valves in the hydraulic modulator assembly. Website: http://www .

Double-clutch transmission: tough conditions for control functions
The double-clutch transmission in the new Passat sets a benchmark in
drivetrain technology, combining the comfort and convenience of an automatic
with the sporting performance and fuel economy of a manual gearbox. The key
advantage of this new transmission is its use of two clutches.
Like all other Volkswagen vehicles, the new Passat uses a CAN gateway from
Continental Temic for this purpose. The result is outstanding deceleration without any of the
disadvantages associated with large wheels such as higher cost and additional
unsprung weight. Precise information on wheel rotation direction and speed
allows these systems to keep wheel slip in the ideal range for optimal
traction under all conditions. Continental Automotive Systems' North
American operation is headquartered in Auburn Hills, Mich. and is a leading
global supplier of quality automotive systems that contribute to driver
safety, comfort and peace-of-mind.
(Logo: http://www. One collective advantage for the
industry is shorter stopping distances. Based on wheel slip observed by the
HPB system during braking, braking forces at the axles are automatically
adjusted to achieve a balanced, efficient use of the brakes .
