CONTROL APPARATUS FOR FUEL INJECTION VALVE

摘要

The present invention suppresses wear on a valve body or valve seat, taking into account the force operating on the valve body, to increase the lifetime number of uses of a fuel injection valve. A control apparatus for controlling a drive current applied to a fuel injection valve having a solenoid, wherein a third pulse signal (421) for applying the drive current to the solenoid is outputted after a first injection pulse signal for injecting fuel has ended and before the start of a second injection pulse signal outputted following the first injection pulse signal for injecting fuel, and the drive current flowing to the solenoid is controlled by the third pulse (421) on the basis of the actual measurement value or the predicted value of the fuel pressure.
