Development of a Brake-by-wire System at TRW Automotive

The concept of "x-by-wire" – originally used for aircraft only – has enormous potential for implementing new car design concepts. The "x" is a wildcard for automotive systems like gearshifting, steering, braking or damping. TRW is developing a new brake-by-wire system using one MicroAutoBox per wheel as an electronic control unit (wheel ECU) and an AutoBox as the main electronic control unit (main ECU).
