BRAKING CONTROL SYSTEM AND METHOD OF VEHICLE
A braking control system and method of a vehicle are configured to safely stop the vehicle by determining whether a brake line fails via detecting a change in braking pressure and compensating for braking force through an engaging operation of an electric parking brake (EPB) when determining that the brake line fails in association with driver manipulation of the brake pedal. The braking control system includes: a vehicle speed detector; a wheel lock detector; a brake pedal operation detector that determines whether a brake pedal is operated; a brake line failure detector that determines whether the brake line fails when the brake pedal is operated; and a controller configured to engage the EPB when a current vehicle speed is equal to or greater than a predetermined vehicle speed, a current state is a wheel-unlock state, and the brake line fails.

ELECTRIC BRAKE APPARATUS, ELECTRIC BRAKE CONTROL APPARATUS, AND BRAKE CONTROL APPARATUS
Wheel speed sensors detect wheel speeds of a plurality of wheels (i.e., a wheel speed of a front left wheel, a wheel speed of a front right wheel, a wheel speed of a rear left wheel, and a wheel speed of a rear right wheel), respectively. A braking control apparatus controls driving of an electric motor. The braking control apparatus drives the electric motor to increase a braking force when the wheel speed sensors detect wheel speed pulses from at least two wheels after a start to maintain the braking force.
