That’s the opinion of German electronics specialist Siemens, which claims the high-tech stoppers, currently being tested for use on upcoming models by Europe’s leading carmakers, will revolutionize the safety standards of future generations of road cars by dramatically shortening stopping distances compared with more traditional hydraulic braking systems.
EWB Braking Technology
Particularly in the automobile sector, there is an increasing trend towards replacing existing hydraulic or pneumatic brake systems with 'drive-by-wire’ solutions.While mechatronics, i.e. intelligent, controllable electromechanical actuators, are already in use in many automotive and non-automotive areas, there are particularly strict requirements for purely electromechanical braking systems which require complex development processes. These are highly safety critical systems, which must provide both excellent control quality and sophisticated fail-safe behaviour. The challenge is to achieve a high power density in the wheel brake actuators.
In early 2005, Siemens VDO Automotive AG acquired the innovative company eStop to enter the automotive brake market with the electronic wedge brake technology. have shown that the EWB concept can produce the high dynamics and high braking torque which are required in modern braking systems by using the standard 12V power supply system. This was first proved by testing the first prototype on an automated dynamometer which simulated the inertia and braking energy of a passenger vehicle.
