TRW Revamps its Regenerative Braking Package for Hybrids and EVs

TRW Automotive has come up with a new generation of regenerative braking system that has been specifically tailored to meet the requirements of Hybrid and electric vehicles. Dubbed Slip Control Boost 2, this Gen II iteration provides the same kind of stopping functionality as TRW's current Slip Control Boost system, but replaces the conventional boosters, master cylinders and vacuum pumps with a completely new electro-hydraulic control unit that's 25 percent smaller and lighter. Peter Lake, executive vice president, sales and business development of TRW Automotive, noted that beyond its advantages in fuel efficiency, packaging flexibility and weight reduction, this latest iteration of Slip Control Boost integrates just as seamlessly with firm's Electronic Stability Control with regenerative braking capability (ESC-R) circuitry to maintain pedal feel and linearity.

TRW is one of the world's largest suppliers of automotive components. Both the 2009 Chevrolet Tahoe and GMC Yukon Hybrids are fitted with its current generation of Slip Control Boost, which also is fully integrated into their sophisticated GM two-mode system on both the regenerative braking and ESC fronts. Beyond existing and future hybrid/EV applications, TRW sees its new SCB2 setup as an ideal match for any vehicle that has either a direct-injection gasoline engine or diesel, as well. Like the original SCB, this enhanced variant can maintain the high pressure levels required to compensate for the lack of sufficient internal vacuum power generated by either of those types of powerplants.
