oh pais.. pelo "lol" nem merecias os 5 segundos q demorei no google.. mas pronto..
Ao contrario dos sistemas normais de controlo de estabilidade, os novos, têm valvulas q permitem controlar com mais precisao a potencia de travagem q é aplicada em cada roda, ao faze-lo de forma analogica, ao inves de ser so ON-OFF, como nos tradicionais.

The next EBS generation is here: MK60E and MK25E
Brake, Electronic Brake Systems, EBS, ABS, ASR, ESP, ESC, MK60E, MK25E
Our concepts for further enhancements of the Electronic Stability Control (ESC)* systems, for the Euroclass and upper class vehicle categories, include a spectrum of additional functions; from a simple ESC system, to a high-end system with the comfort and performance features available on Brake-by-Wire Systems of the future.
Features and improvements
* New generation valve, analog controllable (A/D valves) for optimized wheel control
* Analog controllable cut-off valves (A/D TCS valves) for convenient control of ACC and OHB
* Improved ESC pressure dynamics (in cold by approximately 15%) achieved using a powerful pump and an optimized suction range
* Integrated pressure sensors
* Sensor cluster for yaw rate and longitudinal/lateral acceleration integrated into ECU
* New chip set ER03 for higher integration
* Hydraulic Brake Assist
* Hydraulic ACC
* Packaging and weight optimization
* Improvements in performance of the ABS function are possible through the potential for integrating the wheel pressure information
Possible function extensions
* Deflation Detection System
* Hill Start Assist
* Adaptive Cruise Control
* Cold Start Support
* Rain Brake Support
* Fading Brake Support
* Booster Failure Support
* and further functions

New analog valves for future ESP generations
In addition to these systems, Continental Teves is also supplying the new Astra with front axle calipers, brake booster - for 30 percent of new Astras - and the MK 60 and MK 70 brake systems, the MK 70 being one of the world's lightest ABS assemblies at just 1.7 kilos. The new Astra is the first model to feature innovative hydraulic valves with analog control which boost both the efficiency and ride-comfort levels afforded by the ASR, ABS and ESP control systems. In the past, the brake pressure at the wheels was adjusted by means of digitally controlled valves, which are always either fully open or closed. The new analog valves allow precision adjustment of the flow cross-section available between these two digital extremes, making for less pedal vibration and softer, quieter operation.
