본 발명은, 모터 구동 제어 장치 및 조향 시스템에 관한 것으로서, 더욱 상세하게는, 조향 어시스트를 위한 모터로 모터 구동 전원을 공급하는 인버터 회로와, 제어 전원의 입력 유무에 따라 인버터 회로의 동작을 제어하는 모터 제어 회로와, 제어 신호에 응답하여 모터 제어 회로로의 제어 전원의 입력 여부를 제어하는 스위치 회로를 포함하고, 조향 시스템의 내부 또는 외부에서 고장이 발생한 경우, 조향 어시스트를 위한 모터 구동이 즉각적으로 중단될 수 있도록 해주어 차량 사고를 미연에 방지해줄 수 있다.

    Provided are a motor driving control apparatus and a steering system. The motor driving control apparatus includes an inverter circuit configured to supply a motor driving power to a motor for steering assist, a motor control circuit configured to control operation of the inverter circuit according to whether a control power is input, and a switch circuit configured to control whether to input the control power to the motor control circuit in response to a control signal. When a failure occurs inside or outside the steering system, the apparatus and steering system can immediately stop motor driving for steering assist and thereby prevent a vehicle accident.
