Abstract
Systems and methods for detecting a plunger movement condition with respect to a solenoid coil are described. A method may include generating a first derivative signal waveform of a current flowing in the solenoid coil, identifying whether there is at least one zero crossing point in the first derivative signal waveform, and detecting the plunger movement condition according to an identification result indicating whether there is at least one zero crossing point in the first derivative signal waveform.
