Problems solved by technology

If the flutter movement is too large, this can lead to undesirably large leaks or large energy consumption
Conversely, if said dithering movement is too small or the armature even stops, the hysteresis performance and the dynamics of the valve will be significantly worse

Embodiment Construction

[0036] figure 1 A schematic diagram of a solenoid valve 100 according to an exemplary embodiment is shown. The solenoid valve 100 includes a component 102 for opening or closing the solenoid valve 100 . Part 102 —also referred to as armature or spool—can be moved electromagnetically by means of coil 104 . To this end, the coil 104 is connected to a battery 106 . The component 102 is designed to be brought into a vibration movement by means of the coil 104 , by means of which the static friction of the component 102 can be reduced. In order to actuate the component 102, the solenoid valve 100 includes a device 108 with a sampling unit 110, which is designed to sample a coil raw signal 111 with a predetermined sampling rate—the coil raw signal represents, according to the exemplary embodiment, The current I(t) flowing through the coil 104 and / or also represents the voltage U(t) applied to the coil 104 and is transmitted as the coil signal 112 via the optional averaging unit 1...

Abstract

The invention relates to a method for actuating a component (102) that can be moved by means of a coil (104). In this case, the current flowing through the coil (104) and / or the voltage applied to the coil (104) are sampled for generating a coil signal (112). In a further step, at least one motion parameter ( 116 ) representing a vibration motion of the component ( 102 ) is ascertained using the coil signal ( 112 ). Finally, at least one signal parameter of the dithering signal (122) used to generate the dithering motion is optionally changed by comparing said motion parameter (116) with at least one target value (120) for making said dithering motion consistent with The target value (120) matches.

Description

technical field [0001] The invention relates to a device or a method of the type according to the independent claims. A computer program is also the subject of the invention. Background technique [0002] Electromagnetically actuated valves without displacement sensors are known, the spool or armature of which can perform a small periodic vibrating movement - also called dithering movement - in order to reduce the vibration caused by static friction or vibration during operation. Interference effects caused by hysteresis. If the dithering movement is too large, this can lead to undesirably large leaks or high energy consumption. Conversely, if the dithering movement is too small or the armature is even stationary, the hysteresis performance and the dynamics of the valve will be significantly worse. Typical examples for such valves are hydraulic pressure regulating valves or simple hydraulic continuous valves without displacement measurement. Contents of the invention ...
