Brake pad wear monitoring system and method of controlling the same

A brake pad wear monitoring system comprising:

• a brake pedal sensor configured to detect a displacement of a brake pedal;
• a wheel speed sensor configured to detect each wheel speed of a vehicle;
• a pressure sensor configured to detect a braking pressure of the vehicle;
• and
• a controller electrically connected to the wheel speed sensor and the pressure sensor,
• wherein the controller is configured to:
• perform a brake pad wear determination only when the braking pressure detected through the pressure sensor exceeds a preset pressure during braking of the vehicle,
• in response to the braking pressure exceeding the preset pressure, calculate each of an expected stopping distance and an actual stopping distance of the vehicle based on the detected each wheel speed,
• compare the actual stopping distance with a sum of the expected stopping distance and a predetermined tolerance,
• when the actual stopping distance is greater than or equal to the sum, compare the displacement of the brake pedal with a preset displacement, and
• determine wear of a brake pad when the displacement of the brake pedal exceeds the preset displacement.
