1. An apparatus for controlling pressure of a braking system, comprising:
a pressure sensor configured to detect a pressure value within the braking system mounted in a vehicle, and collect the detected pressure value as an analog pressure signal; and
a control device configured to calibrate the analog pressure signal received from the pressure sensor, convert the calibrated analog pressure signal into a digital pressure signal, and output the digital pressure signal,
wherein the control device sorts the analog pressure signal into duty zones having different levels of precision, and increases the number of measurement points in one of the duty zones requiring high precision to be greater than in the other pressure zones.
