1. An electronic control unit (ECU) assembly structure of a brake system, comprising:
a housing having spaces separated by a partition;
a first control unit and a second control unit which are independently disposed in the spaces separated by the partition;
a first microcontroller unit (MCU) and a second MCU respectively positioned in the first control unit and the second control unit;
a motor controlled by the first MCU or the second MCU to generate a driving force in a hydraulic piston; and
a motor position sensor (MPS) configured to detect a rotational position of the motor,
wherein the second control unit constitutes redundancy of the first control unit to perform the same function,
wherein the motor has a central axis positioned on an extension line of the partition at which the first control unit and the second control unit face each other;
a first MPS and a second MPS are respectively disposed on the first control unit and the second control unit corresponding thereto within a radius of a head of the motor,
the first MPS and the second MPS are positioned on a third printed circuit board (PCB); and
the third PCB is connected to the first control unit and the second control unit through a wire.
