Abstract

A control device for a fuel pump includes a power storage and a discharger. The fuel pump includes an electromagnetic valve. The power storage is configured to store surge current generated upon stopping supplying electric power to the electromagnetic valve. One end of the power storage is connected to a negative electrode terminal of the electromagnetic valve. Another end of the power storage is connected to a power supply. The discharger is configured to connect the power storage and a positive electrode terminal of the electromagnetic valve upon starting supplying electric power to the electromagnetic valve to discharge an electric charge stored in the power storage.
