Brake-by-wire technology represents the replacement of traditional components such as pumps, hoses, fluids, vacuum servos and master cylinders with electronic sensors and actuators. It presently exists on commercial vehicles under the name Electronic Braking System (EBS), manufactured by a few companies. It provides electronic activation of all braking system components, including the retarder and engine braking. EBS still relies on compressed air for braking, only controlling it through valves. It enhances precision over conventional systems, which shortens the braking distance. The fallback of EBS is to switch to ordinary air brake control pressure, so even in the event of an electronic failure, the vehicle will still be able to make a safe stop.
