www.chinabuses.org: BOSCH launched the Generation 9 ESP Premium, which, President of BOSCH Chassis Control System Department Gerhard Steiger said, was "the ideal basis for high-performance assistance and safety systems”.

While current brake control systems work with two pump elements, a total of six pistons are integrated into the ESP® 9 premium. They build up brake pressure especially fast, as well as very evenly, regardless of whether high or low brake pressure is required. On the one hand, this means that the brake control system can brake hard in an instant, and thus defuse critical situations. On the other hand, it can also provide the kind of gentle intervention needed for automatic dry braking or for an adaptive cruise control system with stop-and-go function. This pressure build-up is assisted by two additional pressure sensors integrated in the hydraulic modulator. Moreover, the smooth operation of the pump means that less vibration is transmitted to the bodywork, practically ruling out irksome noises and vibrations on the brake pedal.

Despite all these additional functions, ESP® 9 premium is smaller and 800 grams lighter than its predecessor. This supports automakers’ efforts to reduce the overall weight of new models. Service life has also been increased – for example, by using a modified return pump.
