Abstract

PURPOSE: To effectively control the rotating speed of a fuel pump responsive to a load by detecting a supply current to a drive motor for the pump and controlling the feedback based on the detected value so that the supply current becomes the predetermined value.
CONSTITUTION: When a starter switch and a full throttle switch are closed at the engine starting time, an I/O device 13 produces an "H" level output via a CPU12, and a reference voltage determined by resistors R3, R4 is produced at a point A via the ON or OFF operations of the respective transistors Q1WQ8. This reference voltage is inputted to a control amplifier 16, which conducts a power transistor Q10 to start flowing a supply current IP to a motor for driving fuel pump, and the pump will operate. This supply current IP is produced as a voltage of a resistor R for detecting the current, is applied to the negative terminal of the amplifier 16 via a detecting amplifier 15, and the Q10 is so controlled that the supply current I becomes the predetermined value determined by the reference voltage.
