1. An electronic pedal apparatus comprising:
a pedal pad coupled to a pedal housing via a hinge pin such that the pedal pad is capable of being rotated, the pedal pad being configured to be operated by a driver;
a return spring disposed on the pedal housing such that the return spring extends along a longitudinal direction of the pedal pad, the return spring being configured to provide a return force to the pedal pad;
a connection unit connecting the pedal pad to the return spring, the connection unit being configured to be operated such that a rotational movement of the pedal pad is converted into a rectilinear movement, and the return spring is compressed;
a first permanent magnet coupled to the pedal pad; and
a first printed circuit board (PCB) coupled to the pedal housing facing the first permanent magnet;
wherein the first PCB is configured to recognize a change in magnetic flux of the first permanent magnet, and to generate a signal related to a pedal function when the pedal pad is rotated.
