1. A brake control apparatus of a vehicle, comprising:
a front wheel braking unit implemented as an EMB (Electro Mechanical Brake) and configured to perform a friction braking;
a rear wheel braking unit implemented as a driving motor, and configured to perform a regenerative braking and a plugging braking; and
a control unit configured to:
determine that the vehicle slips at a location where the vehicle is stopped to a stopped state;
control the rear wheel braking unit to perform the plugging braking by switching the rear wheel braking unit to a location-based control to use the plugging braking when the vehicle is stopped to the stopped state by a brake operation; and
control the front wheel braking unit and the rear wheel braking unit by adjusting a braking distribution ratio of a front wheel to a rear wheel to maintain the location of the vehicle where the vehicle slips in the stopped state,
wherein the control unit adjusts the braking distribution ratio of the front wheel to the rear wheel by increasing an amount of the plugging braking of the rear wheel braking unit and decreasing an amount of the friction braking of the front wheel braking unit as much as the increased amount of the plugging braking of the rear wheel braking unit, to maintain the location where the vehicle slips in the stopped state.
