SOLENOID CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/018513
Kind Code:
A1
Abstract:
Provided is a solenoid control apparatus capable of performing control where the generation of large noise from a solenoid is suppressed. A solenoid control apparatus (70) controls a solenoid (30) that has a coil (31), a movable magnetic pole unit (32), and an opposing unit (33). The movable magnetic pole unit (32) is displaced such that a prescribed portion of the movable magnetic pole unit (32) moves in a direction toward the opposing unit (33) or in a direction away from the opposing unit (33). The solenoid control apparatus (70) has a control unit (72) that controls the current that flows to the coil (31). During a portion of a movement period in which the movable magnetic pole unit (32) is moved toward the opposing unit (33), the control unit (72) adjusts the current flowing to the coil (31) such that the movement speed of the movable magnetic pole unit (32) decreases when at least the prescribed portion approaches the opposing unit (33).
