Abstract:
The purpose of the present invention is to provide a fuel injection valve control device with which variability in the injection amount with respect to drive pulse width can be kept to a satisfactory level in each of a plurality of fuel injection devices. The present invention provides a fuel injection valve control device for controlling a plurality of fuel injection devices each equipped with a valve body and a solenoid for opening the valve body, characterized in that the device is configured such that, a prescribed time after voltage has been applied to the solenoid, a holding current is applied, the prescribed time and the holding current being corrected for each of the fuel injection devices, on the basis of the operating characteristics of the fuel injection device.
