The present invention relates to an oil pump driving device for a vehicle. The oil pump driving device for a vehicle includes: a motor driving unit driving a motor for driving an oil pump; a current detecting unit detecting a current of a driving power supply applied to the motor; and a control unit outputting a target RPM of the motor using a PWM signal in the motor driving unit based on an engine RPM and the target RPM of the vehicle received from a main control unit of the vehicle and controlling the driving of the motor by receiving an actual RPM of the motor from the motor driving unit. The motor is formed as a three phase BLAC motor, and the three phase BLAC motor is applied to the oil pump. The driving of the motor is controlled in a magnetic flux standard control method. Therefore, the oil pump driving device for a vehicle can reduce noise of the motor by minimizing torque ripple generated when the motor drives and can drive the motor in a high load area and a low RPM area.

    차량용 오일펌프 구동장치에 관한 것으로, 오일펌프 구동용 모터를 구동하는 모터 구동수단, 상기 모터에 인가되는 구동전원의 전류를 감지하는 전류감지부 및 차량의 메인 제어부로부터 수신된 차량의 엔진 RPM 및 목표 RPM에 기초해서 상기 모터 구동수단에 상기 모터의 목표 RPM을 PWM 신호로 출력하고, 상기 모터 구동수단으로부터 상기 모터의 실제 RPM을 전달받아 상기 모터의 구동을 제어하는 제어부를 포함하고, 상기 모터는 3상 BLAC 모터로 마련되는 구성을 마련하여, 오일펌프에 3상 BLAC 모터를 적용하고, 자속기준제어 방식으로 모터의 구동을 제어함으로써, 모터 구동시 발생하는 토크 리플을 최소화하여 모터의 소음을 저감하고, 고부하 및 저 RPM 영역에서도 모터를 구동할 수 있다는 효과가 얻어진다.
