PROBLEM TO BE SOLVED: To provide a control device of a fuel pump capable of preventing occurrence of a motor lock state.SOLUTION: When a fuel pump actuates, a driving current electrified to a brushless motor 10 for driving the fuel pump is detected. Then, on the basis of the detected driving current, whether the load of the fuel pump is larger than the load at the time of a normal operation is determined, when it is determined that the load of the fuel pump is larger, the rotation frequency of the brushless motor 10 is increased, a discharge amount of fuel due to the fuel pump is increased, and foreign matters resulted in load increase are discharged to the outside of the fuel pump. |
