Siemens VDO has developed a vehicle braking concept consisting of about 30 percent hardware and 70 percent electronics. A 180 degree change from traditional hydraulic braking systems. Electronic Wedge Brake (EWB) System, a low power/low energy 12-volt by-wire braking technology that uses a car’s kinetic energy to stop itself, eliminating the need for hydraulic pipes, brake cylinders, brake boosters or traditional antilock braking control and braking fluid.
