SMALLER AND QUIETER
28 January 2006 - Bosch
Upgraded Bosch ABS goes into production
. Greater convenience due to greatly reduced noise emission · Less installation space required due to more efficient hydraulics · Optimized braking power on slippery surface Bosch has started production of an upgraded version of the antilock
braking system ABS. The hydraulics component of the new ABS 8.1 is some
20 percent smaller and more light weight than the previous version, the
developers moreover succeeded in reducing braking distances even further
especially on slippery surfaces. It is quieter during control actions and
the brake pedal produces less vibrations. ''This new version meets the
objectives of OEMs for a greater reduction of weight and installation
space of every single unit'', explains Klaus Meder, Vice President
Development of the Bosch Division Chassis Systems Control. The essence of the improvements is a more efficient control loop for the
motor of the return pump, the speed of which can now be adjusted to the
driving situation. This allowed engineers to use a smaller sized electric
motor, the decisive factor for achieving a downsizing of the unit. In
addition, pump and valve triggering have been optimized in the course of
the product development. In its most compact version, the box volume of
the hydraulic unit plus add-on ECU now stays below the 1-liter mark and
has a weight of merely 1.4 kilograms. The variable speed control of the
electric motor causes a further reduction of vibrations and the noise
produced in the process. The engineers also succeeded in noticeably
suppressing the intensity of the higher-frequency emitting signals in the
operating noise. This is generally perceived as more pleasant and greatly
contributes to the comfort of the vehicle passengers. On roads with a low
coefficient of friction, that is on wet, snow-covered or icy surfaces,
ABS 8.1 will reduce the stopping distance even further and the lower
power consumption of the compact pump motor will not drain the vehicle
electrical system. Antilock braking systems prevent the locking of wheels when executing an
emergency braking. The vehicle can still be steered - which allows the
driver to slam on the brakes and simultaneously avoid obstacles. Bosch
was the first supplier worldwide to offer an electronically controlled,
mass-produced antilock braking system. It was for the first time
installed in 1978 in the Mercedes-Benz S-Class and a short while later in
the BMW 7series. Ever since, Bosch delivered some 130 million brake
control systems with ABS function to OEMs all over the world. The Bosch Group is a leading global manufacturer of automotive and
industrial technology, consumer goods, and building technology. In fiscal
2004, some 242 000 associates generated sales of 40 billion euros. Set up
in Stuttgart in 1886 by Robert Bosch (1861-1942) as ''Workshop for
Precision Mechanics and Electrical Engineering,'' the Bosch Group today
comprises a manufacturing, sales, and after-sales service network of some
260 subsidiaries and more than 10 000 service centers in over 130
countries. The special ownership structure of the Bosch Group guarantees its
financial independence and entrepreneurial freedom. It makes it possible
for the company to undertake significant up-front investments in the
safeguarding of its future, as well as to do justice to its social
responsibility in a manner reflective of the spirit and will of its
founder. 92 % of the shares of Robert Bosch GmbH are held by the
charitable foundation Robert Bosch Stiftung. The entrepreneurial
ownership functions are carried out by Robert Bosch Industrietreuhand KG.
