This animation explains the brake-by-wire system of the Audi e-tron. The Audi E-tron was the first fully electric vehicle to include brake-by-wire technology. While true brake-by-wire systems would use electronically controlled brake calipers instead of hydraulic pressure, Audi’s system is electrohydraulic. There’s still no mechanical link between pedal and pad but the actuator on the business end of the brakes remain hydraulic; it's just controlled by the computer in response to the amount of pressure the driver puts on the pedal. #Audi #etron #electricvehicle #electriccar
