Integrated electronic brake apparatus and control method thereof

A control method of an integrated electronic brake apparatus including a main control unit mounted in a first area, an auxiliary control unit mounted in a second area, 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, comprising:

• monitoring, by a micro control unit (MCU), whether a driving signal for driving the auxiliary control unit is inputted;
• receiving, by the MCU, one or more of a pedal stroke value from a pedal signal input unit of the auxiliary control unit, a wheel speed value from a wheel speed input unit of the auxiliary control unit, or an EPB (Electronic Parking Brake) signal from an EPB signal input unit of the auxiliary control unit, when the driving signal is determined to be inputted;
• receiving, by the MCU, a status of a vehicle in connection with a peripheral control apparatus within the vehicle through a communication unit of the auxiliary control unit;
• and
• performing, by the MCU, EPB control according to the EPB signal, and controlling an EPB driving unit of the auxiliary control unit to perform a pseudo ABS (Anti-lock Brake System) operation in connection with the peripheral control apparatus based on the pedal stroke value and the wheel speed value,
• 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 a main brake valve for main braking of the vehicle;
• an additional brake valve driving unit configured to drive an additional brake valve for additional braking;
• a motor driving unit configured to drive a brake motor;
• 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, which is the EPB driving unit, configured to operate a parking brake;
• and
• a second MCU, which is the MCU, configured to perform EPB control and control the second EPB driving unit to perform the 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.
