Title: CONTROL DEVICE AND CONTROL METHOD FOR FUEL INJECTION VALVE
Abstract:
A control device for a fuel injection valve includes a drive circuit that controls open/close operation of the fuel injection valve by passing an exciting current through a solenoid of the fuel injection valve and an ECU that reduces a peak current value as a fuel pressure in a delivery pipe at timing of a start of energization of the fuel injection valve decreases. The ECU reduces the peak current value as an amount of fuel discharged from a high-pressure fuel pump to the delivery pipe reduces.
