Title:
電磁駆動弁の制御装置
Document Type and Number:
Japanese Patent JP3743396
Kind Code:
B2
Abstract:
The electronic control unit (50) outputs, to a drive circuit (70), a command current value, which is a value of an attracting current that is desired to be supplied to an electromagnet (61) for driving a valve to be closed or an electromagnet (62) for driving a valve to be opened. In the drive circuit (70), feedback control is performed such that a current which is actually supplied to the electromagnet (61) for driving a valve to be closed or the electromagnet (62) for driving a valve to be opened becomes a command current. In this case, the drive circuit (7) takes in a detected value concerning a distance between the electromagnet (61) for driving a valve to be closed or the electromagnet (62) for driving a valve to be opened, and the armature (28). Then, the drive circuit (70) variably sets a feedback gain used in a feedback based on the distance between the electromagnet (61) for driving a valve to be closed or the electromagnet (62) for driving a valve to be opened, and the armature (28).
