WIPO Patent Application WO/2022/137741
Kind Code:
A1
Abstract:
A control unit according to the present invention stores relationship information indicating a relationship between the rotational speed or the voltage of a motor corresponding to the discharge flow rate of fuel discharged from a fuel pump, and electric current, and a first change point at which a characteristic of the relationship information changes in accordance with a permitted discharge flow rate, and is capable of controlling the rotational speed of the motor, the voltage, or the electric current on the basis of the stored relationship information and first change point. If the temperature of the fuel is less than a predetermined reference temperature, the control unit controls the rotational speed of the motor, the voltage, or the current on the basis of the relationship information in a region less than the first change point.
