Market Successes
Against a background of general market recovery, Knorr-Bremse achieved notable successes in
2010: from Volvo the company received an order to supply compressors for its new mediumduty
engine platform; in Brazil it became the market leader for electronic braking systems; and
in Germany it was voted “Best Brand” in the “Brakes” category of the commercial vehicle sector
for the fifth year in succession.

Electronic brake control system 5.1 at Daimler
This was not the first time that Knorr-Bremse had received an order to supply electronic brake control
systems (EBS) to Daimler AG. But this latest contract nevertheless represented an important milestone,
as the company will now also be supplying the world’s leading commercial vehicle manufacturer with
an EBS system for heavy-duty trucks. The system will be used on the twin-axle semitrailer tractors belonging
to the new SFTP vehicle platform, which means Knorr-Bremse will be supplying about half of
the EBS systems for the platform. Last year the final preparations were made at the Aldersbach site for
series production of components in 2011.
The preparations for production kick-off had been preceded by almost four years’ intensive joint development
work on the system’s software and hardware, including many testing phases both at Knorr-
Bremse and at Daimler. During the year under review the machine tools for production were manufactured
and assembly lines modified so that series production could start on schedule in 2011.
The EBS5.1 brake control system was specifically designed for the requirements of the new vehicle
platform and its new electronic architecture and represents a variant of the EBS5. As a platform development,
EBS5 succeeds in integrating into a single brake control system a wide range of functions that
are now taken for granted in commercial vehicles. In addition to driver assistance systems like the ESP
electronic stability program or the ABS anti-lock system, these also include coupling force control,
wear control and retarder blending.
