Abstract: An electronic pedal apparatus may be operated by a driver with a small force. When the driver operates a pedal pad, the pedal pad is operated with a fine displacement, but a change in a pedal force is increased through compression of a return spring using a rotation lever and a spring guide, so that the driver is capable of easily recognizing an operation situation of a pedal. Furthermore, safety during operation of the pedal may be more enhanced by using a dual sensing structure in which first and second permanent magnets and first and second printed circuit boards (PCBs) are used.
