Abstract:
A set spring force is estimated with high precision and a drive waveform is corrected according to the results. A control device of a fuel injection device consists of an incorporation means of reading a drive voltage of a solenoid, an inflexion point extraction filter for filtering the drive voltage to highlight inflexion points, a means of selecting a later inflexion point or a means of calculating a temporal difference between a later inflexion point and an earlier inflexion point of the extracted inflexion points, and a drive current correction means of correcting a drive current parameter on the basis of timing of the selected, later inflexion point or a temporal difference between the inflexion points.

Claim (Index 2):
A control device of a fuel injection device, the control device controlling current/voltage applied to a solenoid of a fuel injection device on the basis of a drive current parameter to control opening and closing of a fuel injection valve, the control device consisting of:\n an inflexion point extraction filter configured to filter a drive voltage of the solenoid to extract inflexion points; and a drive current correction means configured to correct the drive current parameter on the basis of timing of a later inflexion point of inflexion points extracted by the inflexion point extraction filter or a temporal difference between inflexion points.
