摘要:
A method for controlling a motor of a vehicle fuel pump includes a duty calculation step of calculating, by a motor controller, a duty value of the motor to satisfy a hydraulic pressure of fuel required in accordance with a travel situation of the vehicle, receiving the duty value calculated by the motor controller at the duty calculation step, and determining, by the monitoring unit, whether or not the received duty value is lower than a critical value set in the monitoring unit, and a forced driving step of preventing, by the monitoring unit, a duty value signal from the motor controller from being sent to the motor and directly connecting the motor to a power source, thereby forcibly driving the motor to generate power at a predetermined level when the monitoring unit determines that the duty value calculated by the motor controller is lower than the critical value.
