1. An apparatus for performing electrical braking with a fail-safe function, comprising:
a main brake pedal sensor configured to generate a first output signal proportional to a stroke of a brake pedal;
a main brake controller configured to brake a vehicle by controlling a brake according to a first braking signal based on the first output signal generated by the main brake pedal sensor;
a redundancy brake pedal sensor configured to generate a second output signal proportional to the stroke of the brake pedal, the second output signal having a magnitude within a preset error range from the first output signal; and
a redundancy brake controller configured to brake the vehicle by controlling the brake according to a second braking signal based on the second output signal generated by the redundancy brake pedal sensor,
wherein:
the redundancy brake controller is configured to brake the vehicle when the main brake controller fails, and
the main brake controller is configured to brake the vehicle when the redundancy brake controller fails.
