1. An integrated electronic brake apparatus comprising:
a main control unit mounted in a first area, and configured to receive one or more of an EPB (Electronic Parking Brake) signal, a value from a pedal sensor, a value from a cylinder pressure sensor, or a value from a wheel speed sensor, to perform EPB control, to drive a main brake valve and a brake motor for main braking of a vehicle according to an operation of a pedal, and to drive an additional brake valve for additional braking;
an auxiliary control unit mounted in a second area, and configured to receive one or more of the EPB signal, the value from the pedal sensor, or the value from the wheel speed sensor when a driving signal is inputted thereto, to perform EPB control, and to control an operation of an EPB to perform a pseudo ABS (Anti-lock Brake System) operation in connection with a peripheral control apparatus; and
a connection bus configured to connect the first and second areas mounted in one box to each other, and to transfer a signal transmitted/received between the main control unit and the auxiliary control unit,
wherein the main control unit comprises:
a first EPB driving unit configured to operate a parking brake;
a main brake valve driving unit configured to drive the main brake valve for the main braking of the vehicle;
an additional brake valve driving unit configured to drive the additional brake valve for the additional braking;
a motor driving unit configured to drive the brake motor; and
a first micro control unit (MCU) configured to control the main brake valve driving unit, the additional brake valve driving unit, the motor driving unit and the first EPB driving unit,
wherein the auxiliary control unit comprises:
a second EPB driving unit configured to operate a parking brake;
a second MCU configured to perform EPB control and control the second EPB driving unit to perform a pseudo ABS operation in connection with the peripheral control apparatus,
wherein the second MCU has a lower performance specification than the first MCU of the main control unit such that the first MCU performs the main braking and the additional braking while the second MCU performing the EPB control and not performing the main braking and the additional braking.
