TRW Develops Advanced Braking Technologies

LIVONIA, Mich., Feb. 9 /PRNewswire-FirstCall/ -- TRW Automotive Holdings
Corp. (NYSE: TRW), through its subsidiaries, is developing advanced
regenerative braking technologies that integrate the enhanced safety of
electronic stability control systems for hybrid vehicle and similar
architectures.

The Company is developing two systems -- Slip Control Boost (SCB) and
Active Hydraulic Boost (AHB) -- which offer full braking functionality for
Hybrid Electric Vehicles while incorporating high performance Electronic
Stability Control and brake actuation within a 12-volt system architecture.
The systems can cover a range of vehicles from small passenger cars to Sport
Utility Vehicles.

Slip Control Boost offers a fully integrated TRW stability and brake
actuation system that replaces traditional boosters, master cylinders and
vacuum pumps with an electro-hydraulic control unit (EHCU), and brake pedal
simulator unit with a twin master cylinder to supply brake pressure. This
offers several advantages: (1) ease of installation with fewer components to
fit; (2) improved packaging in the front dash area versus traditional vacuum
boosters; (3) a decoupled brake pedal that is ideal for integration into
autonomous or emergency braking systems; and (4) best-in-class NVH
characteristics. The SCB system is targeted for production in the 2007
calendar year.
