Putting the Brakes on Separate Systems

Gary S. Vasilash

One of the issues related to implementing new technology in cars is that there is a tendency for things to be additive, which means that you have A, add B, then C. . .and before you know it, you have a whole lot of separate things, many of which have to work together, but are individual nonetheless.

TRW Automotive has made a change by developing an integrated system that combines an electric park brake (EPB) and an electronic stability control (ESC) so that there aren’t separate electronic control units (ECUs) for each. Rather, the EPB control functions are performed within the ESC electro-hydraulic control unit.


Done in one.

Explained Josef Pickenhahn, TRW vp of Engineering, Braking, “We can realize significant benefits when integrating the two technologies: reducing system complexity, weight and installation effort, in addition to offering vehicle manufacturers a potential cost reduction from the elimination of the ECU.”

That last benefit, no doubt, has played a role in the fact that European and Chinese OEMs are going to start deploying the integrated TRW system in C, D, E, and MPV vehicle segments in 2014. North American implementation is to occur later.
