摘要： A method of regulating an electromagnetic actuator is disclosed. The electromagnetic actuator has an electromagnet; an armature movable, in a switching step, by a controlled current supply to said magnet coil, from a first armature position to a second, pole face-engaging armature position against a force of a resetting spring. The method includes the following steps for regulating the current flow through the magnet coil to set a low velocity of the armature as it arrives at the pole face: during the switching step, detecting the energy amount in the electromagnetic actuator by detecting a changing armature position and/or a changing armature velocity; estimating by extrapolation the expected energy amount upon arrival of the armature on the pole face; and forming a coarse correcting value by comparing the estimation to be extrapolated with a predetermined target value selected with an aid of the total energy stored in the system in the second armature position.

摘要： A method for characterizing a fluid control solenoid with current compensation is described. A current command is sent to the fluid control solenoid. The current command indicates a desired current value related to a desired fluid output pressure to be applied to the solenoid. An actual fluid output pressure is measured at a valve associated with the fluid control solenoid for the desired current value applied to the solenoid. An actual current received value at the fluid control solenoid is also measured. Post processing is then applied. A compensated current value related to the actual fluid output pressure is determined based on a difference between the current command and the actual current received value. Methods for dynamic current compensation are also described.

摘要： An apparatus detects a position of an armature within a solenoid coil by superimposing a fixed frequency sensing signal onto the coil driver signal. The combined signal is applied to the solenoid coil and an alternating current component varies with changes in inductance of the solenoid coil that result from position changes of the armature. A current sensor produces an output signal indicating a level of current flowing through the solenoid coil and a filter extracts the alternating component of that output signal that results from the sensing signal. A position circuit determines the position of the armature from an output from the filter.

摘要： A method for detecting actuation of an armature associated with a solenoid includes providing a voltage potential to a solenoid coil associated with the solenoid. The method also includes measuring a current flowing through the solenoid coil. The method further includes switching the voltage potential off when the measured current reaches a predetermined maximum value. The method also includes switching the voltage potential on when the measured current reaches a predetermined minimum value. The method further includes measuring a time period between pulses associated with the switching on and off of the voltage potential. The method also includes comparing the measured time period between pulses with predetermined data indicative of an inductance growth level associated with the coil. The method further includes determining, based on the comparison, a pull-in time of an armature associated with the solenoid.
