1. An electronic brake pedal apparatus comprising:
a pedal arm rotatably coupled to a pedal housing;
a plurality of magnet portions connected to the pedal arm and configured to change magnetic flux when the pedal arm rotates;
a plurality of sensor portions configured to detect a change in the magnetic flux of the magnet portions;
a pedal controller fixed to the pedal housing to face the magnet portions and connected to the plurality of sensor portions, the pedal controller being configured to transmit a control signal to a vehicle controller and a braking controller by use of signals of the sensor portions; and
a detecting module disposed between the pedal arm and the pedal controller so that the magnet portions are positioned on the detecting module,
wherein the detecting module includes:
a rotation lever connected to one side of the pedal arm and configured to rotate together with the pedal arm; and
a lever casing fixed to the pedal housing and configured to cover the rotation lever, and
wherein the magnet portions include:
a first magnet coupled to one side of the pedal arm and spaced from a hinge pin coupled to the pedal arm at a predetermined distance, the first magnet being configured to move along an arc trajectory based on the hinge pin when the pedal arm rotates; and
a second magnet spaced from the hinge pin at a distance longer than a distance between the hinge pin and the first magnet, the second magnet being coupled to be rotatable in place at a position on the lever casing.
