Determining the Closing Point in Time of an Injection Valve on the Basis of an Analysis of the Actuation Voltage Using an Adapted Reference Voltage Signal
A method for determining a closing time of a valve having a coil drive may include switching off a current flow through a coil of the coil drive so that the coil is depowered, measuring a time curve of a voltage induced in the non-powered coil, wherein the induced voltage is generated at least parti...

| description | A method for determining a closing time of a valve having a coil drive may include switching off a current flow through a coil of the coil drive so that the coil is depowered, measuring a time curve of a voltage induced in the non-powered coil, wherein the induced voltage is generated at least partially by a motion of the armature relative to the coil, evaluating the measured time curve of the voltage induced in the coil, wherein the evaluation comprises comparing the measured time curve of the voltage induced in the depowered coil to a reference voltage curve stored in an engine controller, and determining the closing time based on the evaluated time curve. The reference voltage curve is thereby adapted to current operating conditions of the valve. A corresponding device and computer program for determining the closing time of a valve comprising a coil drive are also disclosed. |
